Side slope protection drainage structure of asphalt road and construction method thereof

Abstract

The invention discloses a side slope protection drainage structure of an asphalt road. The side slope protection drainage structure comprises frame assemblies laid on the slope surface of the side slope, a plain soil layer, a concrete layer and a gravel layer are sequentially laid in the frame assemblies from bottom to top, and the each frame assembly comprises two symmetrically-arranged anti-collapse frames; the anti-collapse frames comprise side plates perpendicular to the slope surface of the side slope, protruding parts formed on the side plate and protruding towards one side of the side plates, upper edge sections formed between one end of the protruding parts and the side plates, and lower edge sections formed between the other end of the protruding parts and the side plates; and thetwo protruding parts in each frame assembly are opposite in protruding direction, the multiple sets of frame assemblies are arranged, the protruding parts in every two adjacent frame assemblies abutagainst each other, the length direction of each side plate is consistent with the inclination direction of the slope surface of the side slope, and first drainage holes are formed in the upper edge section and the lower edge section. According to the side slope protection drainage structure of the asphalt road and the construction method thereof, water and soil loss of the side slope can be reduced, and safety of vehicles on the asphalt road is guaranteed.

Description

technical field [0001] The application relates to the field of municipal engineering, in particular to a slope protection and drainage structure for asphalt roads and a construction method thereof. Background technique [0002] With the rapid development of my country's infrastructure construction, asphalt roads have become an important part of roads. Compared with cement roads, the hardness of asphalt roads is lower. If the rock on the side slope of the road along the edge If the slope of the slope falls onto the road, it will affect the driving of vehicles on the road, and the rock will have certain damage to the asphalt pavement under the rolling of the vehicle. Therefore, a certain protection is usually carried out on the side slope of the asphalt road to prevent landslides on the side slope, while the existing method is usually to pour concrete directly on the side slope to form a concrete layer on the slope surface of the side slope, so as to prevent side slopes from fa...

AI Technical Summary

Problems solved by technology

[0003] In view of the above-mentioned related technologies, the inventor believes that: during the rainy season, a large amount of rainwater is often accumulated on the slope, and a large amount of rainwater flows down the surface of the concrete layer on the slope, causing the concrete layer on the slope to be damaged under the long-term impact of rainwater. Partial damage causes rainwater to seep into the slope under the concrete layer, and in severe cases, even causes a large area of ​​concrete layer to fall off on the slope, affecting the safety of vehicles driving on the asphalt road
