Embodiment 1

[0037] see Figure 1-6 , in-situ cold regeneration drainage anti-cracking pavement structure, including a frame body 1 with an opening at the top arranged inside the pavement structure, a partition 5 is formed on the bottom inner wall of the frame body 1, and the partition plate 5 divides the frame body 1 into chambers One 101 and chamber two 102 are two chambers, the lower surface wall of chamber one 101 has a port 2, the top of chamber two 102 is equipped with a cover 10, and the cover 10 seals chamber two 102, and the cavity The inner wall of chamber one 101 is formed with a ring-shaped bearing platform 15 and the top of the bearing platform 15 is provided with a water filter plate 18, and a plurality of support rods 17 are fixed on the inner wall of the bearing platform 15. The lower table walls are attached to each other, which improves the bending resistance of the water filter plate 18. The first limit pin 14 and the second limit pin 16 run through the partition plate 5...

Embodiment 2

[0040] see figure 1 and Figure 4 The limiter includes a threaded rod 22 arranged in the horizontal direction between two guide rods one 7, the threaded rod 22 is connected to the inner wall of the chamber two 102 through bearings, and the outside of the threaded rod 22 is screwed with a drive block 8. During the rotation of the threaded rod 22, the drive block 8 moves in the horizontal direction, the drive block 8 runs through the guide rod 2 9, the guide rod 2 9 is fixedly connected with the inner wall of the chamber 2 102, and the guide rod 2 9 runs through Open the avoidance groove 21 on the slide block 11, the avoidance groove 21 is slidingly matched with the guide rod 2 9, and the end of the drive block 8 near the slide block 11 is equipped with a roller 2 27, and the roller 2 27 avoids the drive block 8 and the slide block 11. friction between.

[0041] The difference from Example 1 is that

Embodiment 3

[0043] see figure 1 and Figure 5 , the port 2 is provided with a pressure plate 3, and the bottom inner wall of the pressure chamber 101 is fixed with a column 4, and the column 4 runs through the through hole 24 provided on the pressure plate 3, and the ball 12 is installed on the inner wall of the through hole 24, under normal conditions , the pressure plate 3 is attached to the bottom cavity wall of the chamber one 101 and seals the port 2, which can avoid the overflow of the odor and play a deodorizing effect. When there is water in the chamber one 101, the pressure plate 3 Under the action of buoyancy, the upward movement can facilitate the discharge of accumulated water. At the same time, the top of the pressure plate 3 is set in a conical shape, which can prevent heavy objects from accumulating on the top of the pressure plate 3. The ball 12 avoids the gap between the column 4 and the wall of the through hole 24. The friction between them makes the movement of the pre...

Abstract

The invention discloses an anti-crack pavement structure with in-situ cold regeneration and drainage, which comprises a frame body with an opening at the top arranged inside the pavement structure. Chamber 1 and chamber 2 are two chambers, the lower surface wall of chamber 1 has an opening, and the top of chamber 2 is provided with a cover. In the present invention, the water filter plate is placed on the top of the bearing platform, and under the action of the second spring, the two sliders are given elastic force close to each other. Since the outer walls on both sides of the slider are all inclined, the rollers can be given a limit. The elastic force of position pin 1 and position limit pin 2 moving to the interior of chamber 1, position limit pin 1 engages with position limit hole 2, and position limit pin 2 engages with position limit hole 1, which plays a role in fixing the filter plate. The effect is improved, the stability of the water filter plate is improved, and the water filter plate is prevented from being moved by vehicles or stolen by criminals.

Description

technical field [0001] The invention relates to the technical field of pavements and roads, in particular to an in-situ cold regeneration drainage anti-cracking pavement structure and a cold regeneration pavement construction method. Background technique [0002] Road construction is one of the most important basic projects at present. The drainage system in the road structure is an important basic structure, and the road surface filter device in the drainage system is one of the important components. [0003] In the present water filter device, comprise the water filter plate that is arranged on the road surface, the accumulated water on the road surface flows into the underground drainage system through the water filter plate. Most of the water filter plates in the prior art are placed on the road, and their design is not reasonable enough. During use, they are easily driven by vehicles or stolen by criminals, which brings great safety hazards to road traffic. Contents ...
