Problems solved by technology

[0006] The purpose of the present invention is to overcome the existing problems in the prior art: large cross-section anti-slide piles are rigid structures, and are prone to large deformation, anti-slide piles shearing or displacement under the action of high-intensity earthquakes; the anti-slide pile structure cannot be effectively Eliminate the problem of groundwater in the sliding body, which may easily lead to increased sliding force, and provide an anti-sliding pile component with anti-seismic drainage function and its construction method, which can greatly reduce the deformation, shearing or displacement of the anti-sliding pile under the action of high-intensity earthquakes probability, as well as reducing the sliding force of the sliding body, greatly reducing the impact of groundwater in the sliding body against sliding piles or retaining walls

Embodiment 1

[0041] Such as Figure 1-3 As shown, an anti-slide pile assembly with anti-seismic drainage function, including anti-slide pile 4, retaining wall 5, buffer drainage layer 6, fixed anchor rod 7, water collection well 8, drainage pipe 9, drain hole 10, water-resisting layer 11;

[0042] The anti-sliding pile 4 is made of reinforced concrete, which passes through the sliding body, and the lower end is anchored in the stable sliding bed; the retaining wall 5 is located around the anti-sliding pile and is made of reinforced concrete for maintaining anti-sliding during excavation. The pile hole wall is stable to avoid collapse;

[0043] The buffer drainage layer 6 is located behind the retaining wall 5, and can deform under the action of an earthquake to absorb the inertial force generated by the earthquake, and at the same time drain the groundwater in the sliding body to the bottom of the buffer drainage layer 6; the buffer drainage layer 6 is made of geosynthetics The compositi...

Embodiment 2

[0051] Such as Figure 1-3 As shown, a construction method for forming the anti-slide pile assembly described in this embodiment, the construction steps are:

[0052] A1. Excavate 4 pile wells for anti-slide piles in sections, and the excavation depth of each section is 0.5-2m;

[0053] A2, the buffer drainage layer 6 consistent with the excavation depth of the anti-slide pile 4 pile wells is fixed on the pile well wall with the fixed anchor rod 7;

[0054] A3. Construction of reinforced concrete retaining wall 5;

[0055] A4. Repeat steps A1 to A3 until the excavation reaches 3 places on the sliding surface;

[0056] A5, lay the water-repelling layer 11 at the bottom of the buffer drainage layer 6, and install the drain hole 10;

[0057] A6. Excavate 4 pile wells for anti-slide piles in sections, and the excavation depth of each section is 0.5-2m;

[0058] A7. Construction of reinforced concrete retaining wall 5;

[0059] A8. Repeat steps A6 to A7 until the bottom of ant...

Abstract

The invention relates to the field of landslide prevention and control, in particular to an anti-sliding pile assembly with an anti-seismic drainage function and a construction method of the anti-sliding pile assembly. The anti-sliding pile assembly with the anti-seismic drainage function comprises an anti-sliding pile, a protective wall sleeves the anti-sliding pile, a buffer drainage layer is arranged on the water-facing side of the protective wall, and a drainage device is arranged at the bottom of the buffer drainage layer. According to the anti-sliding pile assembly with the anti-seismicdrainage function, the seismic inertia force directly assumed by the anti-sliding pile is reduced, a role in improving the seismic resistance of the anti-sliding pile is played, and the sliding forceof a sliding body is reduced, and the impact of groundwater in the sliding body on the anti-sliding pile or the protective wall is greatly reduced.

Description

technical field [0001] The invention relates to the field of landslide prevention and control, and specifically relates to an anti-slide pile component with an anti-seismic drainage function and a construction method thereof. Background technique [0002] In recent years, my country's infrastructure construction has developed rapidly, and a large number of railway and highway projects have been implemented in high-intensity earthquake areas, such as the Sichuan-Tibet Railway, which passes through a large number of eight-degree and nine-degree earthquake areas along the line. Secondary disasters such as landslides and rock piles occur frequently in high-intensity earthquake areas, causing great troubles to infrastructure construction. [0003] Anti-slide piles are the main measures for landslide prevention and control. Anti-slide piles pass through the landslide body and go deep into the slide bed to support the sliding force of the slide body and stabilize the slope. They ar...
