Description

Technical Field

[0001] This invention relates to the field of auxiliary processing equipment for road construction, specifically to a rapid leveling device for road construction and its construction method. Background Technology

[0002] Road surface smoothness is one of the main technical indicators for evaluating road surface quality. It relates to driving safety, comfort, the magnitude of impact forces on the road surface, and its service life. Uneven road surfaces increase driving resistance and cause additional vibrations to vehicles. In areas with a network of waterways, uneven roads can also trap rainwater, accelerating water damage to the road surface. Therefore, in order to reduce vibration and impact forces, improve driving speed, and enhance driving comfort and safety, road surfaces should maintain a certain degree of smoothness.

[0003] In existing technologies, road leveling relies on a single laser signal or manual calibration, which is prone to errors when the base layer has large undulations or changes in material slump (such as concrete segregation). In addition, laser equipment has poor adaptability to the construction environment (such as strong light and dust), and the sensor is easily interfered with, resulting in a decrease in accuracy. At the same time, existing laser leveling equipment cannot make relevant judgments on the condition of the roadbed. Summary of the Invention

[0004] The purpose of this invention is to provide a rapid leveling device and its construction method for road construction, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a rapid leveling device for road construction, comprising: an anti-settlement base disposed on the road base, a connecting seat for connecting the anti-settlement base, an anti-pressure signal terminal for generating a reflected signal, and a vehicle-mounted measuring mechanism for detecting spacing. The anti-settlement base is disposed in the roadbed and is a precast concrete pyramidal base. The anti-settlement base is placed and filled after the roadbed is compacted. The connecting seat is inserted during the prefabrication of the anti-settlement base and is an integral structure with the anti-settlement base. The anti-pressure signal terminal is fixed to the top of the connecting seat. Multiple anti-pressure signal terminals are evenly distributed at the bottom of the road. The height of the anti-pressure signal terminals is adjusted during installation. Multiple vehicle-mounted measuring mechanisms are mounted on the inspection vehicle.

[0006] Furthermore, the vehicle-mounted measuring mechanism includes a connecting base plate, a telescopic column, a mounting base plate, a traveling wheel, a detection plate, a guide column, and a compression spring. The connecting base plate is horizontally fixed to the testing vehicle. The telescopic column is slidably connected to the connecting base plate via a sliding sleeve. The mounting base plate is fixed to the bottom of the telescopic column. The traveling wheel is fixed to the bottom of the mounting base plate. The detection plate is annular and fixed to the mounting base plate. The detection plate emits a sensing signal and receives a reflected signal, and detects the spacing of the signal source according to the time difference. The guide column is fixed to the mounting base plate, and the guide column and the connecting base plate are slidably connected via a guide ring. The compression spring is sleeved on the telescopic column, and both ends of the compression spring respectively press against the connecting base plate and the mounting base plate.

[0007] Furthermore, the internal part of the pressure-resistant signal terminal is a metal block for reflecting signals, while the external part is a corrosion-resistant and pressure-resistant engineering plastic that wraps around the metal block.

[0008] A rapid leveling construction method for road surface construction, the specific steps of which are as follows: The first step is to lay and compact the roadbed to ensure that it does not collapse or deform. Then, install the anti-settlement base by drilling installation holes and use laser equipment to adjust the horizontal height of the anti-pressure signal terminal before filling it. The second step is to lay the top layer of road material normally and construct the road surface according to the procedure. During the leveling and compaction stage, the gap between the road surface and the anti-pressure signal terminal is continuously detected by the inspection vehicle. Combined with the material replenishment and compaction process, the gap is adjusted to within the range. The third step is to use a testing vehicle to check the distance between the road surface and the anti-pressure signal terminal after the road is repaired. In the same way, the distance is adjusted to within the range by combining the filling and compaction process.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: The rapid leveling device and construction method for road construction of the present invention sets an anti-settlement base on a hard roadbed, and an anti-pressure signal terminal is set on the upper end of the anti-settlement base. Then, using an on-board measuring mechanism set on a detection vehicle, the distance between the anti-pressure signal terminal and the road surface is continuously detected as the vehicle travels on the road surface. Since the anti-pressure signal terminal has been adjusted to a horizontal height, as long as the detected distance is controlled within the error range, it is sufficient. During construction, the distance can be adjusted to within the error range in combination with the filling and compaction processes, thus ensuring that the final road has a high level. When the road needs to be repaired, after the repair is completed, the distance between the road surface and the anti-pressure signal terminal is detected using the detection vehicle. Similarly, the distance can be adjusted to within the error range in combination with the filling and compaction processes. At the same time, changes in the roadbed can also be detected.

[0010] This invention has the advantages of simple structure, safety and effectiveness, and good performance. Attached Figure Description
