1、收费岛施工方案（Construction scheme for toll island）The construction organization design scheme (2007-01-24 17:03:06) has been reproduced in the highway toll collection stationHighway plan recharging renovation worksConstruction organization design1. Quality control before constructionIs mainly refers to th2、e construction preparation stage before construction, we mainly grasp the following several aspects: open clarificaiton will design units, supervision units, construction units, mechanical and electrical contractor, weighing equipment suppliers to attend the meeting, interpretation of the meter weig3、ht principle, make construction personnel understand weight charge equipment on the island of lane toll plaza, charge, charge.The construction unit to evaluate compound Examining construction units of recent performance, engineering command system, engineering quality level, the number of the worker4、s and technicians, check whether the key type of work has the mount guard qualification certificate, instrument and meter is national metrology inspection certificate of quality supervision department, understand the state of machinery, vehicles, equipment equipped with can meet the construction req5、uirements, etc.To review and inspect the quality assurance system, quality site management measures, project schedule and safety protection measures for the construction organization.Audit equipment and order the construction unit of the specifications of the equipment procurement contract, model, t6、echnical indicators should be carefully checked whether conform to the requirements of the provisions of the contract, the main material before entering the construction site for information about the test and certificate of quality inspection.The construction site investigation of communication pip7、elines have been completed, power line, people (hand) hole based, transformer room, computer room, and so on carries on the detailed investigation, review construction design drawings is complete and correct.2. Quality control of construction process2-1 in the construction supervision project, the s8、upervision office will start from the organizational leadership, scientific management, update supervision philosophy and bold innovation, so that the quality, safety and environmental protection of the project will be strictly controlled.The inspection and inspection of strict procedures shall be c9、arried out in accordance with the design standards and process requirements, and the quality acceptance standards of the construction procedure shall be prepared for the critical process. This time we process the acceptance variable construction units according to the project construction process to10、 apply for inspection to active inspection, in accordance with the construction process quality inspection earnestly, to meet the requirements of the quality of the scene to sign to recognize, is not in conformity with the quality requirements in a timely manner, construction units rectification req11、uired. Failure to enter the next procedure is not acceptable. Great extent eliminates the active supervision engineering quality hidden danger and accident, and also a one-time qualified for completed process inspection and sign recognition in time, make the project smoothly under the process of con12、struction, control the quality and speed up the construction schedule.Build system of model project key disciplines engineering or process, to select a heavy toll lane, a toll station as a model project for demonstration, through summarizing, construction unit put forward the construction technology13、 standard of specification, with the approval of the owner, supervision after all. Each process of this project was first conducted in ninglian high-speed huaian mainline toll booth, and summarized the experience. It was a good result to organize the visit and study.Adhere to the supervision enginee14、r of the sidelines, according to the work order of the construction unit, the general procedure will not leak the prison,Key position key supervision. If the weight equipment foundation pit size is strictly according to the manufacturers drawings, the concrete marking and curing time of the water sh15、all be satisfied.2-2-2 this project should improve the precision of weighing equipment and the stability of the charging system, and form the following points in the process of quality supervision.2-2-1 control the speedSpeed is directly related to the precision of weighing equipment. By measuring i16、nstrument for testing, to test the vehicle static weighing equipment accuracy is above 99%, and the speed of 5 km/h when weighing equipment precision reaches 95%, and when the speed is greater than 5 km/h when weighing equipment precision would be badly affected. Measures are as follows: in the high17、way exit, before weighing about 500 meters, set up the logo vehicle deceleration within 5 km/h, not to accelerate, decelerate and slamming on the brakes, to ensure the accuracy of weighing system measurement, reducing the possibility of dispute; Set the deceleration line and decelerate block, and wh18、en installing the deceleration block, it should be noted that when the vehicle passes the deceleration block, it will also hit the brake symmetric platform to impact the precision (variable speed) when passing the weighing platform. Normally not less than 18 meters in front of the weighing equipment19、.It is recommended to display the speed on the lane control display (according to the current interface provided by the weighing device). In this way, the toll collector can report the speed of the vehicle on the basis of the actual situation, and it is very convincing to some drivers who want to ta20、ke advantage of it.2 2-2-2 civil engineering requirementsTo ensure that the test is completed before the vehicles arrive at the toll booths, the length of the charging island should be extended appropriately, and the speed control of the driver through the platform shall be considered for the conven21、ience of the pilot. Rebuilt charging island: demolition reconstruction island head tail (island), within the scope of cutting excavation toll plaza concrete pavement, the construction of the island itself lengthening period and the new island head tail (island), and adjust the affected by the altera22、tion of equipment is designed according to the new arrangement and set up new equipment foundation; New entrance unidirectional charge island: the entrance unidirectional charge island has fog lamps, manual railings, lane cameras, traffic lights, automatic railings; New export one-way charge island:23、 export fog lamps on the island of one-way charge hand hole, hand railings, heavy equipment, control box, raster vehicle lane separator, weighing display, traffic signal, camera, the traffic signal lamp, automatic rail; The toll island and toll booth foundation: the charging island and the toll boot24、h foundation are horizontal in the cross-section direction, and the longitudinal section is the same as the longitudinal slope of the road, the lowest side of the top surface is 25cm from the surface of the road. Charge island protection: ahead of the toll booths set up 2 root 219 * 10.0 mm steel pi25、pe anticollision column, on both sides of toll booths set up cold bending square steel crash barriers, to ensure that the toll collector, charge craft and equipment safety; The paving of the toll island: the paving of the toll island shall be made of colored cement squares, and the colors, specifica26、tions and old islands shall be unified or determined by the construction unit; Charge island facade sign: island facade tag should be used by GB5768-1999 ordinary paint yellow black or red and white alternate with, line 15 cm intervals, charging island head aluminum reflective film, monochromatic 1527、 cm width, to increase the reflective effect of the night.The location of the platform will not span the cement plate, so as to prevent the cooling of the heat, the platform will be safe. The platform is installed in the middle of the driveway.The horizontal, vertical and vertical slope of the table28、 should be consistent, but the slope should not be greater than 2%. If said before and after the road slope is greater than 2% should be broken cement road surface, large heavy pouring cement pavement, leveling, control according to the slope, and the road smooth transition and weighing table, fight29、 said passing vehicles of vehicle, the turbulence.An additional control box, a weighing screen foundation and a hand hole are added on all the export side charging island, with a horizontal drainage pipe in the hand hole leading to the side slope. Special attention should be paid to the horizontal d30、rainage pipe center along the road and slope direction must have Angle, Angle to 15 to facilitate drainage. The bottom elevation of the hand hole is based on the base of the platform (if the water tank is set at the bottom of the hand hole, it can also be reached into the water tank). If the water i31、n the table can affect the precision of weighing equipment.From the base of toll booth to the front hand hole of the island, the steel tube was installed in the front hand hole of the island, and the base of the weighing screen was added before the end of the island, and connected with the steel pip32、e on the basis of the toll booth. If the distance between the traffic signal and the toll booth is not long enough, the weighing screen and the traffic signal will be fitted to the same post.2-2-3 installation of equipmentFreight vehicle standard in our country is not greater than the total length o33、f 18 meters, so weighing equipment installed in 18 meters distance charge window location, short distance will lead to some super long car arrived in charge the window to the rear of the vehicle is not all by weighing mesa, long distance, in general the speed will be relatively faster, or vehicles i34、n the variable state probability is bigger, affect the weighing precision. Because of the irregularity of individual vehicles, so weighing installation mesa is apart from the toll booths window than 18 meters, 18 to 23 metres or so commonly, so also facilitate vehicle queue, ensure that say a car, t35、o pay the cost of a car. The glass surface of the infrared vehicle separator is easy to frost in winter. It is recommended that the windshield of the car should be used to heat the windshield to remove the frost. The weighing display shall include at least the model, the excess capacity, the amount 36、and the standby two lines. The screen should work all the time, with dust, rain and sun protection. The brightness should be guaranteed to be clearly visible to the division crew within a range of 20 metres under various lighting and natural environment conditions; Now displays are generally LED, so37、 best can turn 15 , when installation is this display of the passenger, is easy to see.3. Equipment installation3-1 person (hand) hole and square cameraTo increase the charge fee of lane toll plaza, the corresponding increase toll booths under the manhole, set new shoulder outside the shoulder in th38、e expansion of the manhole, affected the expansion of the early to dismantle the toll plaza of hand hole and based on the new toll plaza cameras3-2 equipment foundation and pipeline3-3 toll booths4. Quality control after completion of the projectTo conduct the delivery, completion inspection and acc39、eptance according to the contract. Verify that the completed data and the completed drawings are in conformity with the actual construction and complete and accurate. Check the work load and defects, supervise the construction unit to complete the period until the issuance of the certificate of resp40、onsibility for the defect.The measurement accuracy of the rechargeable equipment needs to be improved.Domestic optional manufacturer is not many, and the price of foreign equipment is higher, maintenance is not very convenient. To fully embody the thought of people-oriented, let the driver has the right to appeal, it is recommended to increase export square side outline a set of low speed/static portable review equipment, set up the simple overloading enforcement pavilion, pavilion with management computer, printer and other equipment.
