Embodiment 1

[0027] refer to figure 2 , image 3 , Figure 4 , the drainage pipe of the present embodiment comprises an outer pipe 1, the front portion of the outer pipe 1 has a water hole 2, the outer pipe 1 is provided with an inner pipe 13, the inner pipe 13 is flexibly connected with the outer pipe 1, and the inner pipe 13 can be moved from Outer tube 1 is drawn out, and the end of inner tube 13 is provided with shovel 14, and shovel 14 is fixedly connected with inner tube 13, and the cross section of outer tube 1 and inner tube 13 is circular.

[0028] The method of using drainage pipes in this embodiment to reduce the groundwater level of the slope sand layer is applicable to the situation where there are no springs or there are springs but the water volume of the springs is small. The specific method is as follows:

[0029] (1) Refer to Figure 5 , put the end of the drainpipe with the shovel 14 forward, push the drainpipe into the landslide 3;

[0030] (2) Pull out the inner p...

Embodiment 2

[0037] The drainage pipe structure of this embodiment is the same as that of Embodiment 1.

[0038] The method of using drainage pipes in this embodiment to reduce the groundwater level of the slope sand layer is applicable to the situation where there are springs and the water volume of the springs is relatively large. The specific method is as follows:

[0039] (1) Excavate the water collecting well 5 near the spring hole 15 on the upper part of the slope protection 9;

[0040] (2) Refer to Figure 5 , put the end of the drainpipe with the shovel 14 forward, push the drainpipe into the landslide 3;

[0041] (3) Pull out the inner pipe 13 of the drain pipe, and take out the sandy groundwater in the shovel 14 at the end of the inner pipe 13 and discharge it along the drain pipe 1;

[0042] (4) Put the inner pipe 13 into the outer pipe 1, and continue to push the drain pipe into the landslide 3;

[0043] (5) Take out the inner pipe 13 of the drain pipe, take out the sand and...

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. In an environment with many groundwater flows, the mechanical propertie...
