Drainage pipe and method used for dealing with side slope sliding by using drainage pipe

Abstract

Provided are a drainage pipe and a method used for dealing with side slope sliding by using the drainage pipe. The drainage pipe comprises an outer pipe, an inner pipe is arranged in the outer pipe, the inner pipe is movably connected with the outer pipe and can be drawn out of the outer pipe, and a shovel is arranged at the end of the inner pipe and fixedly connected with the inner pipe. The invention further comprises the method used for dealing with side slope sliding by using the drainage pipe. The drainage pipe can drain underground seeping water of soil layers such as water-containing sandy oil and completely weathered granite on a revetment and a retaining wall, and can also drain concentrated spring water which is on the revetment and the retaining wall and inconvenient to drain off, thereby effectively lowering underground water levels of the soil layers such as the water-containing sandy oil and the completely weathered granite on the revetment and the retaining wall, strengthening mechanical properties of side slope soil and reaching the purposes of stabilizing a side slope, dealing with side slope sliding, facilitating construction of the revetment and the retaining wall, improving the construction quality of the revetment and the retaining wall, effectively using the site, saving cost, guaranteeing smooth implementation of a construction project and ensuring the personal safety of constructors.

Description

technical field [0001] The invention relates to lowering the underground water level of the sandy soil layer of a slope, in particular to a drainage pipe and a method for using the drainage pipe to deal with the sliding of a slope. Background technique [0002] At the slope with a large height difference, slope protection 9 and retaining wall 10 are usually built. In soil layers such as sandy soil and fully weathered granite with rich groundwater, especially in the southern rainy season, when the slope protection 9 and retaining wall 10 are constructed, the groundwater level of the sandy soil and fully weathered granite and other soil layers above the slope protection retaining wall is often high, resulting in slope Instability, forming a landslide 3. refer to figure 1 , the existing treatment method is to drive steel anti-slide piles 4 into the landslide 3, but the treatment effect is often not good.

Problems solved by technology

refer to figure 1 , the existing treatment method is to drive steel anti-slide piles 4 into the landslide 3, but the treatment effect is often not good. In an environment with many groundwater flows, the mechanical properties of the project are extremely poor. In this way, not only the construction quality of the slope protection and retaining wall cannot be guaranteed, the construction of the project cannot be carried out, but also the land used for the planned construction project will be occupied, which wastes resources and seriously endangers the implementation and construction of the construction project. personal safety of personnel
