Embodiment 1

[0054] Such as figure 1 , figure 2 , image 3 , Figure 4As shown, a pavement structure with a load cell includes a concrete road base 42, a load cell 1 and a concrete pavement layer 4, the concrete pavement layer 4 is laid above the concrete road base 42, and the load cell 1 is arranged on the sensor bracket 2 Above, the sensor bracket 2 is fixedly connected to the concrete subgrade 42, and the fixing method of the load cell 1 and the sensor bracket 2 can be bolt fixing, bayonet fixing and other fixing methods. The sensor bracket 2 is fixedly connected with the concrete road base 42 through the socket, and the concrete road base 42 is marked and positioned, and then drilled. The drilling depth is 8CM-15CM, which is to match the insertion length of the sensor bracket 2 legs. , Inserting the legs into 8CM-15CM can make the sensor bracket relatively stable and fix the load cell 1 at the same time. The depth of the foundation pit 41 is 20CM-50CM, and the depth can be determi...

Embodiment 2

[0056] Such as Figure 5 A pavement structure construction method with a load cell is shown, comprising the following steps:

[0057] S1: Positioning and laying out the original road surface 5;

[0058] S2: cutting the original road surface 5;

[0059] S3: Grinding the reference plane 51 on the surface of the original road surface 5;

[0060] S4: Excavating the foundation pit 41 in the area surrounded by cutting the original road surface 5;

[0061] S5: Concrete road base 42 is poured in foundation pit 41;

[0062] S6: Drill holes on the surface of the concrete subgrade 42, install the sensor bracket 2 in the hole, and fix the load cell 1 on the sensor bracket 2;

[0063] S7: pouring the concrete pavement layer 4 in the foundation pit 41;

[0064] S8: Fixedly installing the ground induction coil 6 on the surface of the concrete pavement layer 4 .

Embodiment 3

[0066] Position and set out the original road surface 5, use a tape measure to measure at the pre-selected position on the original road surface 5, measure according to the size requirements of the construction drawings, and use a marker pen to mark each measurement point, and then use an ink fountain to measure each measurement point. During the work of setting out and drawing lines, use the road cutting machine to cut on the original road according to the drawn line. Generally, the depth of the cutting seam is between 5cm and 15cm.

[0067] Use a water mill to grind the original road surface 5 surface within the scope of each 50cm on the left and right sides of the cut seam, and use a 3m long ruler and feeler gauge to measure while grinding. The gap formed by the polished surface of the original road surface 5 cannot be filled with a 3 mm thick feeler gauge, and the polished surface meets the flatness requirement of the reference plane.

[0068] The original road surface 5 i...

Abstract

The invention relates to the field of intelligent transportation, and a construction and installation method of road traffic detection equipment. A pavement structure with a weighing sensor is disclosed, which includes a concrete road base, a load sensor, a load sensor support and a concrete pavement layer, and the load sensor is arranged on the sensor support. This pavement structure can greatly improve the smoothness of the concrete pavement and the service life of the load cell, and the pavement is not prone to cracks and high and low staggered platforms, making the equipment run more stably. In addition, a road surface structure construction method with a load cell is also disclosed, which mainly includes the following steps: pouring a concrete subgrade in the foundation pit; drilling a hole on the surface of the concrete subgrade, installing a sensor bracket in the hole, and fixing it on the sensor bracket Install the load cell; pour the concrete pavement layer in the foundation pit. The construction method of this pavement structure can effectively reduce the construction cost and construction difficulty, shorten the construction period, and facilitate the maintenance of equipment and pavement in the later stage.

Description

technical field [0001] The invention relates to the field of intelligent transportation, and a construction and installation method of road traffic detection equipment, in particular to a road surface structure with load cells and a construction method thereof. Background technique [0002] The off-site law enforcement system is a product of the development of modern intelligent transportation technology. It is used to detect relevant parameters such as vehicle speed and vehicle weight in high-speed driving, which can greatly reduce the work intensity of traffic law enforcement personnel, reduce the interference of human factors, and promote fairness. , Fair law enforcement plays a vital role in controlling vehicle speeding, overrunning and overloading. [0003] At present, the general road construction method of the load cell in the off-site law enforcement system is to harden the road surface with concrete, then place the load cell in the cut groove by setting out wires an...
