This time we process the acceptance variable construction units according to the project construction process to apply f

10、or 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 required. T

11、he above procedure can not enter into the next process construction. 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

12、 of construction, 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 tec

13、hnology 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

14、engineer 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 w

15、ater shall 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 meas

16、uring instrument 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 t

17、he highway 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,

18、 and when 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 eq

19、uipment.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 wan

20、t to take 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

21、 convenience 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

22、 alteration 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

23、island: 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 to

24、ll booth 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 s

25、teel pipe 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, sp

26、ecifications 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, monochrom

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

28、ddle of the driveway.The horizontal, vertical and vertical slope of the table 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 acc

29、ording to the slope, and the road smooth transition and weighing table, fight 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 le

30、ading to the side slope. Special attention should be paid to the horizontal drainage pipe center along the road and slope direction 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

31、 hand hole, the drain pipe can also be reached into the water tank). If the water in 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 weigh

32、ing screen was added before the end of the island, and connected with the steel pipe 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 equi

33、pmentFreight vehicle standard in our country is not greater than the total length of 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

34、 mesa, long distance, in general the speed will be relatively faster, or vehicles in 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 2

35、3 metres or so commonly, so also facilitate vehicle queue, ensure that say a car, to 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

36、weighing display shall include at least the model, the excess capacity, the amount and the standby two lines. The display screen 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 rang

37、e 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.
