13、o select a heavy toll lane, a toll station as a model project for demonstration, through summarizing, construction unit put forward the construction technology standard of specification, with the approval of the owner, supervision after all. Each process of this project was first conducted in ningli

14、an 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 engineer of the sidelines, according to the work order of the construction unit, the general procedure will not leak the prison,Key position key sup

15、ervision. If the weight equipment foundation pit size is strictly according to the manufacturer's drawings, the concrete marking and curing time of the water shall be satisfied.2-2-2 this project should improve the precision of weighing equipment and the stability of the charging system, and for

16、m 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 instrument for testing, to test the vehicle static weighing equipment accuracy is above 99%, and the speed of 5 km/h when weighing equipm

17、ent 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 highway exit, before weighing about 500 meters, set up the logo "vehicle deceleration within 5 km/h, not to accelerate, decelerate and

18、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 when installing the deceleration block, it should be noted that when the vehicle passes the deceleration block, it will also h

19、it 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 equipment.It is recommended to display the speed on the lane control display (according to the current interface provided by the weig

20、hing 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 take advantage of it.2 2-2-2 civil engineering requirementsTo ensure that the test is completed before the vehicles arrive at

21、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 convenience of the pilot. Rebuilt charging island: demolition reconstruction island head tail (island), within the scope of cuttin

22、g 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 alteration of equipment is designed according to the new arrangement and set up new equipment foundation; New entrance unidirectio

23、nal charge island: the entrance unidirectional charge island has fog lamps, manual railings, lane cameras, traffic lights, automatic railings; New export one-way charge island: export fog lamps on the island of one-way charge hand hole, hand railings, heavy equipment, control box, raster vehicle lan

24、e 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 booth foundation are horizontal in the cross-section direction, and the longitudinal section is the same as the longitudinal slo

25、pe 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 pipe anticollision column, on both sides of toll booths set up cold bending square steel crash barriers, to ensure that the to

26、ll 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, specifications and old islands shall be unified or determined by the construction unit; Charge island facade sign: island facade tag

27、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 15 cm width, to increase the reflective effect of the night.The position of the installation platform cannot span the expansio

28、n joint of the cement plate, in case the hot and cold shrink will be called the decca death, guaranteeing the safety of the platform. The platform is installed in the middle of the driveway.The horizontal, vertical and vertical slope of the table should be consistent, but the slope should not be gre

29、ater 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, fight said passing vehicles of vehicle, the turbulence.An a

30、dditional 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 drainage pipe center along the road and slope direction

31、 must have Angle, Angle to 15 ° to facilitate drainage. The bottom elevation of the hand hole should be base on the platform (if the water tank is set at the bottom of the hand hole, the drain pipe can also be reached into the water tank). If the water in the table can affect the precision of w

32、eighing 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 pipe on the basis of the toll booth. If the

33、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 of 18 meters, so weighing equipment instal

34、led 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 in the variable state probability is bigge

35、r, 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, to pay the cost of a car. The glass surfac

36、e 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 and the standby two lines. The display sc

37、reen should work all day long, with dust proof, rain protection 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, so best can turn 15 °, when installation is this display of the passenger, is easy to see.3.
