Threaded tube within a water wall, deterioration of heat transfer does not occur. X turbine cold starts, heat transfer of steam to the cylinder wall is based on condensation heat tran20、sfer and convective heat transfer in two ways at the same time. (X) the furnace higher excess air coefficient, smaller chemical heat loss due to incomplete combustion. () Boiler of soda expansion is inevitable. Start-up incorporations, boiler-DC operation, adjustment of main steam temperature contro21、l in a coal-water ratio between points. A single swirl burner burning adjacent burners are not required to support. Swirl burners with different rotation direction will affect the boiler steam temperature and load parameters. X boiler steam flow is divided with double built-in startup separator desi22、gned for community process. During combustion of pulverized coal in boiler, oxygen content, the lower the NOx is produced more. When the gas-water ratio imbalances, once-through boiler steam temperature at each point in the trip will change, and closer to the pop tour entrance, inertia and hysteresi23、s temperature change is smaller. In disguise near the heat transfer coefficient of steam increases to a maximum at first and then quickly lower. Control of start-up separator outlet steam temperature, that controls the boiler heating and evaporation, thermal heat distribution. (X) as the direct curr24、ent requirements for operation of the boiler feedwater quality was much higher than that of drum boiler, in once-through boiler start-up process, therefore there is no need for furnace washing of Silicon.

(4) with the personnel concer34、ned to carry out the measurement of quality and safety checks, and technical information. (5) according to the data, to the conservation section chiefs will report on the situation. Four job agencies, conservation management to achieve good conservation, achieve a standard, we must establish a sound35、 management system, to ensure smooth progress. Under the unified leadership and management at different levels, to ensure that the concentration of decision-making power and unity of command, and a chain of authority, management at different levels; Division of labor and cooperation, so that the wor36、king groups towards the direction of professional development to ensure corporate goals and conservationComponent objectives of coordination, collaboration on the various functions of the body in action, coordination between the functional departments and managers, the entire management organization37、s to ensure that capable, efficient, multi-functional. Under the Chongqing Municipal landscaping management standards and the technical specifications of urban landscaping projects adopt the following approach working mechanism. Will this unit dedicated to the conservation section is divided into fo38、ur groups: the trees and shrubs to the conservation group (responsible for measures such as the shading); full-time mechanical maintenance group (responsible for watering, cooling, spray during the day), lawn maintenance groups and plant groups. Section with garden plant professional engineer 1, eac39、h equipped with the professional technician 1, 2 technicians, carry out their duties. By the Resident Engineer of the conservation section chiefs and marketing grasp work and coordination. After five, lawn maintenance and management of plant construction, often with a 1-2 lawn maintenance can grow i40、nto the fullness of the week. After the lawn grow, but also to carry out regular maintenance and management, to ensure the lawn landscape continues for a long time. Lawn maintenance management including: irrigation, fertilization, pruning, weeding and other links. 1, irrigate irrigation lawn fertili41、ty environments can be improved, adding water plant the lawn, is a guarantee of normal lawn. In view of the lawn during the growth season, lawn and the environment is in a State of flux, coordination of water and soil and improving the microclimate of the Center, water cannot be implemented accordin42、g to a fixed pattern, following a number of technical points for reference. (1) the irrigation time growing season, according to the different periods of precipitation is extremely important and timely irrigation of different grass species. Can generally be divided into three periods: turned green b43、efore the rainy season. High temperatures during this period, transpiration, water requirements, and is one of the most crucial irrigation under soil water retention properties of strength and rainy periods during which Bush 2-4. largely ceased during the rainy season irrigation. Air humidity during44、 this period, grass transpiration decreased soil moisture content has increased to a level sufficient to meet the needs of lawn growth. to yellowing of the leaf after this period before the rainy season precipitation, evaporation is greater, while the lawn is still in a great stage of life activitie45、s, compared with the previous two periods, lawn water requirements increase at this stage, if not timely irrigation, not only affect the growth of grass, also causes yellow. At this stage, according to 4-5 of irrigation. In short, grass types, water requirements are different, you mustAccording to t46、he climate conditions and plant species to determine irrigation of the lawn. About a day, when irrigation is better depends on irrigation. In theory, the same period as long as the amount of irrigation water is less than the infiltration capacity of the soil, irrigation all the time in a day. Then d47、epends on the irrigation way. If intermittent intermittent spray or spray irrigation (high degree of atomization), irrigation is best with the Sun. Not only can add moisture, but also significantly improve the microclimate and photosynthesis and transpiration and gas exchange, facilitated the coordi48、nation of water, air, fertilizer and soil thermal and vegetative organs of root and root expansion, and could lead the entire transit storage of the plant material, breathing, lawns and lush. If using water, irrigation, and so on, should be watching season, early spring, late autumn around the heel 49、as well and the rest take twilight as much. (2) irrigation irrigation quantity should be based on the soil, growing, grass and other factors to determine. General lawn growing season drought period, takes about a week to pay 20-40mm; vigorously growing lawn in the heat and severe drought situations,50、 need to pay 50-60mm per week or more. In General, regardless of the method, should be irrigated more than once, each time less water, maximum surface runoff that just occurred. 2, fertilizing to maintain lawn dark green leaves, grows, portions must be fertilized. Lawn plants for leaf growth and blo51、ssom-free requirements, so nitrogen is more important, response to nitrogen fertilizer is the most obvious. Should be basic application in building lawn, lawn built in growing season required after applying fertilizer. Cold season grass dressing time is best in early spring and fall. After the first52、 green, can play a role in facilitating the growth of second in spring, after the weather turned hot, you should stop dressing. Fertilization in autumn on 9, October. Applies fertilizer the time is late spring of warm-season grasses. In a month or 2 months of growing season to be caught up with fert53、ilizer. Increasing the density of foliage, improve resistance to stepping on. Fertilizing should not be late for the last time in mid-September. 3, trim Pruning is the focus of lawn maintenance, but is the most intensive work. Trim control lawn height of the tillers, increasing the density of leaves54、, weeds and lawn neat and beauty. General lawn trimmed at least 4-5 times a year, prune and trim the number of height is related to two factors. Lower the cutting height requirements, pruning more times. Leaves of grass density and coverage also increases with the number of trim and more. It should 55、be noted that in accordance with regular mowing the grass cutting height, when up to 1.5 times the height of the grass, trim twice times the maximum shall not exceed the specified height. 4, weed weed invasion will seriously affect the quality of the lawn, turf lost uniform and neat appearance and p56、urpose weed and grass competition for water, fertilizer, race the Sun, so that objective grass growth decline, so weed is an essential part of lawn maintenance and management. The fundamental methods of weed prevention and removal is the rational management of water and fertilizer, grass growth prom57、otion purposes, increase competitiveness with weeds, and multiple trim, suppress weeds. Case against weeds, in addition to using artificial rejects, I also use chemical herbicides, such as killing dicotyledonous weeds with 2.4-d class; using ximajin, prometryn, Diuron, closed soil inhibited germinat58、ion of weed germination or kill weeds; sterilant herbicide, Diuron, and other lawn or lawn weed control of updates. Herbicide use is complicated, effect change over a number of factors, improper use can cause great losses and therefore should be carefully tested before use and preparation, concentra59、tion, tools used should be responsible. 5, the pierced holes on the lawn of ventilation holes, aims to improve the ventilation of roots, soil moisture content, to improve the effect of fertilization. The work to improve the quality of turf plays an important role. General requirements for 50 points/60、m2, 15cmx5cm hole spacing and hole diameter 1.5-3.5cm, cave deep 8cm hollow Iron Rod man-tie hole available, we can use lawn punching machine (restore root aeration machine) purposes. Root cutting comb comb the grass on the lawn, remove excess grass, improve the quality of grass growth. Lawn with ha61、d larger load or often by load of role, soil harden, can used lawn vertical trim machine, with milling knife dug wide 1.5-2.0CM, and spacing for 25cm, and deep about 18cm of ditch, in ditch within fill into more hole material (as sponge soil), put dug of soil turned came, and put remaining soil ship62、ped go, application efficient fertilizer, and fill broadcast grass seed, strengthening fertilizer management, lawn can soon growth complex strong. Six, green cultivation and management of the emergency remedy 1, strengthen of the seedlings increased planting more trees in drought resistance. In the 63、right amount at the right time in growing with compost, irrigation, promoting tree growth, tree sugar accumulation of nutrients in the body and can enhance the trees resistance. Autumn fertilization must be stopped as soon as possible, so as to avoid long, shoot too late lignification, anti-freeze. 64、2, protected crowns and roots. Filling pile of dirt at the root Crown after cold winter water is very effective, usually 20-30 cm tall pile of dirt and solid. 3, package. Before the winter with straw or rope . The following points: to select agents, prevent plants from harm. II in the valid range sh65、ould use low concentrations of pesticides. Should pay attention to using different medicaments to prevent pest resistance. may use high pollution, high residues of drugs and interfere with each other, improve control. plant protection practice must be performed to ensure that human and animal safety66、. Seven, plant maintenance and management standards (a), pruning standards: 1, hedge trimmer, plastic plants: plants with plastic requirements should be carried out in a shoot out 15cm trim, hedgerow should ensure the smooth, clear, distinct. After the summer, we finally look forward to short term b67、ridge engineering practice. This practice is an essential part of the learning process. While, we will in internship of process in the on reality in the of bridge has more directly of contact and study, such on we of courses of learning certainly is favourable of, on the, through this internship eve68、ryone on yihou of work environment, and work content also has has deeper of understand, this on is careers employment of we for, undoubtedly will produced is big effect, we then of select will more of rational carefully. After the internship is over, I am very satisfied. This internship I learned as69、 a peoples pride of place in road and bridge in the future. It is under the efforts of generations of people in road and bridge, bridge construction in China has been developing by leaps and bounds. Construction of road and bridge engineering in China with large scale, high speed, technical level ha70、s been greatly improved, and in some areas they have leading positions in the world. For example the practice seen in Hangzhou Bay Cross-Sea Bridge and Sutong bridge and other heavy-weight works all reflect the strength of bridge engineering. But in spite of this, we would like to see my level of so71、me shortcomings, such as innovation in bridge design, as in project organization and management, in architecture, for example on the use of new materials, which are in the construction of bridge engineering gap with advanced countries. After this internship, we are national 985 University students a72、s outstanding reserve force of national highway and bridge specialty, our responsibility is great. You cant deny that bridge, Southeast University student component in the national counterparts are significant. So we are on the countrys future has a great influence on the development of road and bri73、dge construction, which requires that we now learn professional knowledge, with better expertise at a later time. I cant say this bridge we are failing, that our nations roads and bridges is a failure, it is frog in the idea! but we dont succeed, say is failure to bridge education in Southeast Unive74、rsity. This internship I learned a lot, and practice experience is difficult to explain with just two or three sentences. In order to describe well, I order writing my practice report by practice date.8.20 is the first day of practice, rode through Hangzhou Bay Cross-Sea Bridge，Much world attention.75、 Beginning of the construction of Ningbo Municipal Government explicitly proposed bridge project in accordance with the three top objectives standard to implement. Facing a complex build environment, challenging projects, organize and manage the bridge is placed in front of the headquarters of the g76、reat challenges. Many construction jobs, long front, existing synchronization job, cross process, the construction organization， After you come down from the Cross-Sea Bridge, and then we went to Shi Tang Heng Jiang bridge construction site. Ten Tang Heng Jiang bridge as a significant landscape brid77、ge in Ningbo Hangzhou Bay new zone, very beautiful for the design. Questions: 1, twin rectangular structure to ensure a concrete casting in dense, according to General Manager of field projects, rectangular structure the concrete pouring is not guaranteed in full density, can only be detected later.78、 He referred to the detection of three things: one is the use of ultrasonic testing, the other is the pouring of the concrete volume compared with the volume of rectangular components. In late testing, structure evaluation of housing a grade. Only the lower level again when pouring but in order to a79、chieve a better effect of pouring, a self-compacting concrete was used by the project. 2, twin tower structure in balance. To this end they expert with Tongji University Tower design with a balanced system.Later in the course of the project PPT presentation, we also understand the characteristics an80、d difficulties of the project, cause Im more interested in is the construction of steel structure of main tower. The perimeter of the main tower made of welded steel plate, after steel plate welded into the rectangle and then pouring concrete. During construction of the main tower, construction unit81、 went out on loan from 31 heavy industry group for hoisting two large-tonnage crane machines. Construction of steel structure of main tower is by sections, each segment the weight shown in the table below, we can see the difficulty of construction. Large sections of the Tower weightIn ten Tang Heng 82、bridge watch during our first so directly contact with the bridge in construction State. This allows us to have a deeper feeling. First, as a bridge with the landscape, its design was more brilliant, two tilt Bridge viewed from the distance and rely on each other when the main tower structure, turne83、d out to appear in the scene, we will issue voice of praise. We walked to the nearby looking at more than 80 metres from the main tower, its tall and stands in contrast to our small and. I was for the first time this kind of bridge-building technology, both design and the construction of tracks! 8.284、1: the first task of the day is to go to Hangzhou subway tunnel excavation site. We walked about a kilometer from the tunnel into the distance to the under construction section. Because only a temporary erection of the access tunnel is a narrow way, so we are basically does not go without interrupti85、on all the way. We never made much. Todays second task is to watch the new intersection of Tang Lu Jingfang road connection of underground space engineering. Underground space connection project of xintang Lu Jingfang road intersection in new pond road intersects with Fengqi road junction road, Feng86、qi road along the new road direction setting. Construction of engineering structures using open-cut method. Works for the underground two-layer double-or two-story three-Bay rectangular frame structure, retaining structure with diaphragm wall, wall thickness 800mm. Support standard first line of con87、crete support + 4 steel support, first concrete support the shield section + 4 steel support (the 5th double steel backing for support). Main standard pit depth 16m depth of end well in Foundation pit of 17.5M. Subsidiary structure in total 9 entrance and 3 Wind Pavilion. According to this there is 88、a project of urban underground space engineering features and difficulties. I are as follows: 1 the pipeline: the works surrounding the main gas, electricity, light current, water supply and other important pipelines, pipeline Manager Basic and parallel to the pit, part of a pipeline crossing the pi89、t needs to be protected. 2, pit monitoring: this works on both sides of the Community traffic, and many surrounding buildings, five farmers markets in particular distance near pit, strictly controlling deformation of Foundation pit by the Department for this project, the monitoring of Foundation pit90、. 3, unearthed in the pit: as the project is located in the city center, excavation of large earth-moving required when shipping, this is subject to reasonable arrangements planned and coordinated work on the outskirts of unearthed. 4, traffic: the project covering 7 traffic organization during cons91、truction, the project has been completed the main structure of a traffic organization and Fengqi road traffic organization work. Transport organizations directly related to the projects construction progress.8.21: the first task of the day is to go to Hangzhou subway tunnel excavation site. We walke92、d about a kilometer from the tunnel into the distance to the under construction section.
