Problems solved by technology

Due to irregular construction, soil deposition, etc., the drainage holes of the slope retaining structure and the filter layer behind the structure are prone to clogging, resulting in the failure of the drainage function of the filter drainage system of the slope retaining project
If any reinforcement measures do not solve the problem of reverse filter drainage system repair, it will not achieve lasting and stable results, and currently widely used reinforcement components such as anchor rods, anchor cables, etc. do not have drainage functions

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] refer to figure 1 , The drainage anchor rod of the present invention includes a drainage pipe 10 and an anchoring pipe 20 formed through a connecting member 30 to form an axially detachable butt joint. refer to figure 2 , On the pipe wall of the drain pipe 10, small drainage holes 11 are scattered, and the outer end of the drain pipe 10 is connected with an outer anchor steel plate 12. The drain pipe 10 and the anchor pipe 20 are generally made of hollow threaded steel pipes of φ50˜φ60 mm. The small drainage holes 11 are arranged in such a way that, on the cross section of the drainage pipe 10, the small drainage holes 11 are circumferentially spaced on the pipe wall except the 60-degree fan-shaped surface at the bottom.

[0015] refer to image 3 , the outer wall of the connecting member 30 has a radially outwardly extending annular shoulde...

Abstract

The invention discloses a drainage anchor rod, a side slope protection engineering repairing and reinforcing structure and a construction method; the side slope protection engineering repairing and reinforcing structure can reinforce the side slope protection engineering, also can effectively repair an inverted filtration system of the side slope protection engineering, obtains lasting and stable effect, has a simple structure and is easy to construct. The drainage anchor rod comprises a drain pipe (10) and an anchoring pipe (20), wherein the drain pipe (10) and the anchoring pipe can be axially detached or butted by a connecting member (30); small drain holes (11) are dispersedly arranged on the wall pipe of the drain pipe (10); and the external end part of the drain pipe (10) is connected with an external anchoring steel plate (12).

Description

technical field [0001] The invention relates to a slope retaining project, in particular to a drainage anchor with drainage performance, the repair and reinforcement structure of the existing slope retaining project formed by using the drainage anchor, and the repair and reinforcement of the existing slope retaining project Construction method of construction. Background technique [0002] After the slope retaining project is completed and used for a certain period of time, there will be defects such as cracking of the retaining wall and partial collapse, which need to be rectified through measures such as reinforcement. Due to irregular construction, soil deposition, etc., the drainage holes of the slope retaining structure and the filter layer behind the structure are prone to clogging, resulting in the failure of the drainage function of the filter drainage system of the slope retaining project. If any reinforcement measures do not solve the problem of filter drainage sy...
