Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] This utility model provides a technical solution: such as Figure 1 and Figure 2 As shown in this embodiment, an anti-rutting asphalt pavement for heavy traffic includes an asphalt layer 7. By adding an anti-rutting agent, the asphalt layer 7 can significantly improve the anti-rutting ability of the asphalt pavement, improve the viscosity and elasticity of the asphalt, and reduce the formation of ruts. A waterproof mortar layer 2 6 is provided on the bottom side of the asphalt layer 7, and a concrete layer 5 is provided on the bottom side of the waterproof mortar layer 2 6. A drainage well 8 is provided between the concrete layer 5, the waterproof mortar layer 2 6, and the asphalt layer 7. An impurity collection structure 9 is installed inside the drainage well 8. A compressive strength layer 4 is provided on the bottom side of the concrete layer 5, a crushed stone layer 3 is provided on the bottom side of the compressive strength layer 4, a waterproof mortar layer 1 2 is provided on the bottom side of the crushed stone layer 3, and a roadbed 1 is provided on the bottom side of the waterproof mortar layer 1 2. By setting up a multi-layer asphalt pavement structure, the strength of the asphalt pavement can be strengthened.

[0029] like Figure 2 and Figure 3 As shown, the compressive layer 4 includes a frame 41, with slots 42 arranged on the inner side of the frame 41. Inserts 43 are inserted into the inner walls of the slots 42, and partitions 44 are fixedly connected to the outer side of the inserts 43. The frame 41 is composed of several partitions 44 spliced ​​together, with two adjacent partitions 44 inserted together. Cross-shaped compressive plates 45 are fixedly connected inside each partition 44. The gaps between the partitions 44 and the cross-shaped compressive plates 45 are filled with mortar filler. By setting the compressive layer 4 on the bottom side of the concrete layer 5, the strength of the asphalt pavement is further improved, which can delay and reduce cracks caused by repeated rolling of heavy-duty vehicles in heavy-duty traffic sections.

[0030] like Figure 4 and Figure 5As shown, the impurity collection structure 9 includes a water collection hopper 91, a collection filter cylinder 92 bolted to the bottom of the water collection hopper 91, a support plate 93 on the upper inner wall of the water collection hopper 91, a screw 94 between the middle of the support plate 93 and the bottom of the inside of the collection filter cylinder 92, a sleeve 96 threaded to the outer wall of the screw 94, a knob 95 on the top side of the screw 94, a collection filter plate 97 bolted to the outer surface of the sleeve 96, a support groove 81 on the upper inner side of the drainage well 8, a well cover 82 embedded in the top side of the drainage well 8, a water leakage groove on the well cover 82, and an annular support plate 911 fixedly connected to the upper part of the outer surface of the water collection hopper 91, the annular support plate 911 supporting the support groove 81. The ring support plate 911 is bolted together with handles 912 at both ends. The outer surface of the collection filter plate 97 is slidably connected to the inner side of the collection filter cylinder 92. By setting the impurity collection structure 9 in the drainage well 8, impurities can enter the collection filter cylinder 92 along with the rainwater. The impurities are filtered through the mesh and collected on the collection filter plate 97, thereby preventing the sewer from being blocked by the entry of impurities. When cleaning the impurities, simply open the well cover 82 and turn the knob 95 to raise the collection filter plate 97, which makes it easy to clean the stored impurities. In addition, the collection filter cylinder 92 is designed to be deep, which can store a lot of impurities and only needs to be cleaned once in a long while.

[0031] This utility model provides an anti-rutting asphalt pavement for heavy traffic. The specific working principle is as follows: the strength of the asphalt pavement is improved by laying multiple layers. At the same time, the partition frame 44 and the cross-shaped anti-compression plate 45 are set in the frame 41 by splicing. The gaps between the partition frame 44 and the cross-shaped anti-compression plate 45 are filled with mortar filler. In rainy weather, rainwater and impurities enter the drainage well 8 through the manhole cover 82. The set collection filter cylinder 92 stores the impurities and collects them in the collection filter plate 97. On a sunny day after a period of time, the collection filter cylinder 82 is opened and the knob 95 is turned to make the screw 94 rotate, thereby pushing out the collection filter plate 97 along with the collected impurities for easy cleaning.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
