Slope protection drainage structure and construction method of renewable asphalt road

Abstract

The invention discloses a slope protection drainage structure of a renewable asphalt road. The slope protection drainage structure comprises a concrete layer poured on the surface of a slope and a drainage assembly arranged on the concrete layer; the drainage assembly comprises prefabricated steel bars, prefabricated steel strips and Z-shaped drainage tiles, wherein one ends of the prefabricated steel bars are arranged in the concrete layer and fixed to the concrete layer in a condensed mode, one ends of the prefabricated steel strips are arranged in the concrete layer and fixed to the concrete layer in a condensed mode, and the drainage tiles sleeve the prefabricated steel bars; the prefabricated steel bars are distributed on the surface of the concrete layer in a rectangular array, the prefabricated steel strips are distributed on the surface of the concrete layer in a rectangular array, and the prefabricated steel strips and the prefabricated steel bars are alternately arranged in the extending direction of the slope; the drainage tiles are laid on the concrete layer and alternately connected end to end, and the prefabricated steel bars are fixed to the drainage tiles connected end to end. The slope protection drainage structure has the advantages that the slope protection drainage structure and a construction method thereof are beneficial to preventing the concrete layer on the slope from falling off, and safety is high.

Description

technical field [0001] The invention relates to the field of slope construction, in particular to a slope protection and drainage structure of a renewable asphalt road and a construction method thereof. Background technique [0002] Today, with the rapid development of my country's infrastructure construction, renewable asphalt roads have become an important part of mountain roads. Compared with cement roads, the pavement hardness of renewable asphalt roads is lower. If the rocks on the slope fall onto the road along the side slope, it will affect the driving of vehicles on the road, and the rocks will cause certain damage to the asphalt pavement under the rolling of the vehicles. Therefore, a certain amount of protection is usually carried out on the side slope of the renewable asphalt road to fix the rock on the side slope and prevent the side slope from landslides. However, the existing method is usually to pour concrete directly on the side slope. A concrete layer is for...

[0003] However, in the rainy season, a large amount of rainwater is often accumulated on the slope of the mountainous area, and a large amount of rainwater flows down the surface of the concrete layer on the slope, causing local damage to the concrete layer on the slope under the long-term impact of rainwater, causing rainwater to seep into the concrete On the slope under the layer, it will cause the concrete layer and the slope surface to loosen, and even cause the concrete layer on the slope to fall off in a large area in severe cases, affecting the safety of vehicles driving on the renewable asphalt road
