Reinforcement cage seepage drainage pipe for quickly lowering seepage line in side slope body

Abstract

The invention discloses a reinforcement cage seepage drainage pipe for quickly lowering a seepage line in a side slope body. The reinforcement cage seepage drainage pipe is formed in a way that geotechnical cloth (2) wraps a reinforcement cage pipe, wherein the reinforcement cage pipe is of an integrated structure formed by combining four longitudinal supporting steel bars (3) with the same length, two longitudinal reinforcing ribs (4), transverse supporting wire rods (5) which are arranged at equal intervals and transverse reinforcing ribs (1) which are arranged at equal intervals, and the four longitudinal supporting steel bars (3) with the same length are respectively welded on the upper, lower, left and right parts of the inner sides of the transverse supporting wire rods (5) which are arranged at equal intervals so as to form the reinforcement cage pipe. The reinforcement cage seepage drainage pipe has the characteristics of easiness and convenience in construction, high reliability and high water permeability, the seepage drainage and precipitation functions in the side slope body can be preferably achieved, the seepage line in the slope body is effectively lowered, the number of drill holes is reduced, the slope treatment scheme is optimized, the investment cost is saved, the drainage pipe is not easy to clog in the slope body, the reliability is high, the service cycle is long, and the seepage drainage requirement of the side slope can be preferably met.

Description

technical field [0001] The invention belongs to the technical field of slope body drainage, and in particular relates to a seepage drainage pipe for reducing the infiltration line in the slope body, which is suitable for different rock mass / soil mass slopes, especially for soils with low permeability coefficient and poor water permeability The seepage drainage of the slope can realize the rapid reduction of the infiltration line in the slope body to ensure the safety and stability of the slope body. Background technique [0002] There are two factors affecting slope stability: intrinsic and extrinsic. The internal factors include the physical and mechanical properties, internal structure, structural surface, and ground stress of the slope rock and soil mass, and these factors often play an important role in controlling; the external factors are mainly the effect of water, that is, there are mainly two types: The role of surface water and groundwater. Surface water and grou...

Problems solved by technology

[0005] (1) Due to the structural influence of the drainage pipe, the opening is small and easy to block, and its drainage effect is limited in the vertical and horizontal directions, the drainage effect is reduced, and it is easy to fail for a long time;

[0006] (2) Due to the stiffness of the material, the number of openings on the pipe wall is limited, and the openings can only be made on the upper half wall of the pipe. The water permeability is not good. In order to achieve the drainage effect, it is necessary to increase the distance between the drainage pipes and increase the cost.

[0007] (3) After practice tests, due to the low water permeability of plastic drainage pipes and they are very prone to clogging, and the water in the slope cannot be discharged in time, the soil will be soaked in water for a long time, the soil will soften, and the strength will decrease, which significantly reduces the slope. The security and stability of the system requires additional reinforcement and governance measures, which increases the investment cost

However, compared with the prior art, the drainage efficiency of the seepage pipe has not been fundamentally improved
