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...
