Novel replaceable hard and rigid combined double-layer curved-grain net-shaped pervious pipe for slope

Abstract

The invention discloses a novel replaceable hard and rigid combined double-layer curved-grain net-shaped pervious pipe for a slope. The novel replaceable hard and rigid combined double-layer curved-grain net-shaped pervious pipe comprises an outer pipe, an inner pipe, a top cover and a bottom cover. The outer pipe is a semi-pervious type curved-grain net-shaped pervious pipe body, and the outer wall face of the outer pipe is provided with first curved-grain ribs and first pervious holes. The inner pipe is a full-pervious type curved-grain net-shaped tough pervious pipe body, and the outer wall face of the inner pipe is provided with second curved-grain ribs and second pervious holes. The inner pipe is detachably sleeved with the outer pipe. According to the novel replaceable hard and rigid combined double-layer curved-grain net-shaped pervious pipe for the slope, the construction cost can be indirectly reduced; and the good long-term use performance is achieved, so that the maintenance cost can be greatly reduced. Due to the technical advantages of replaceability of a new material and a new technology in the process of maintaining and governing sludge plugging of backwards-slanting drain holes, corrosion resistance, admissible hardness, circular rigidity, flexibility, durability of pipes and other aspects, application and popularization intensity can be enlarged so that the technology can serve for engineering construction as soon as possible, and more economic and social benefits are created.

Description

technical field [0001] The invention relates to the technology in the field of row number engineering, in particular to a new type of replaceable hard-tough combination double-layer curved mesh permeable pipe for slopes. Background technique [0002] In the slope treatment projects of highway, water conservancy, geotechnical engineering, etc., laying horizontal and inclined drainage holes is a frequently used drainage treatment method. For a long period of time, the original inclined drainage holes installed during the slope construction period used the traditional design method of materials such as PVC plastic pipes wrapped in geotextiles or soft permeable pipes. After the operation period, the drainage function gradually attenuates, or even fails, so that the long-term effect of the slope treatment project cannot be guaranteed, endangering the stability of the project and the safety of road traffic. In addition, traditional materials such as PVC or flexible permeable pipe...
