Embodiment 1

[0044] figure 1 It is a side view of the anti-slide pile of this embodiment. figure 2 It is the sectional view of the anti-slide pile of the present embodiment (along figure 1 Middle A-A direction).

[0045] Figure 1-2 The anti-slide pile shown includes a load-bearing section 100, an embedded section 200 and an enlarged section 300, wherein the loaded section 100 is located between the sliding surface 500 and the slope surface 400, and the embedded section 200 is located on the sliding surface 500, the enlarged section 300 is located between the loaded section 100 and the embedding section 200 and is located below the sliding surface 500; the anti-sliding pile is formed by integral casting of reinforced concrete.

[0046] The total length of the anti-slide pile is 18m, of which, the length of the loaded section 100 is 9m, the length of the embedded section 200 is 6.3m, and the length of the expansion section 300 is 2.7m.

Embodiment 2

[0054] Figure 4 It is the sectional view of the anti-slide pile of the present embodiment (along figure 1 Middle A-A direction).

[0055] Compared with embodiment 1, the difference that the anti-slide pile of the present embodiment has is: as Figure 4 As shown, the cross-section of the anti-slide pile is circular, and the cross-sectional diameter of the enlarged section 300 is equal to 1.5-3 times the cross-sectional diameter of the embedding section 200; the cross-sectional diameter of the embedding section 200 is 1-2m.

Embodiment 3

[0057] Such as Figure 5 The slope reinforcement device shown is a single row of anti-slide piles obtained by arranging the anti-slide piles in Example 1 at a distance of 2 to 3 times the length of the extended side.

Abstract

The invention discloses an anti-slide pile, a slope reinforcing device and a slope reinforcing method. The anti-slide pile comprises a load bearing section, an embedding section and an expanding section, wherein the load bearing section is located between a sliding surface and a slope surface; the embedding section is located below the sliding surface; the expanding section is arranged between theload bearing section and the embedding section and located below the sliding surface; and the cross sectional area of the expanding section is larger than the cross sectional area of the load bearingsection and the cross sectional area of the embedding section. Thus, by arranging the expanding section, on the one hand, the action area of the top of the embedding section on extrusion of a slidingbed can be increased, the stratum resistance within the local range of the top of the embedding section is effectively reduced, and the requirement for the horizontal bearing capacity of a foundationat the position is easily met; and on the other hand, the depth of the embedding section can be reduced, the pile length is shortened, the anti-slide pile is more economical and reasonable, and construction operation is easy. Thus, the anti-slide pile is simple in structure and ingenious in conception, and the overall stability of a slope body can be improved.

Description

technical field [0001] The present invention relates to the technical field of landslide control or side slope reinforcement, in particular to the technical field of anti-slide piles, in particular, to anti-slide piles, a side slope reinforcement device and a side slope reinforcement method. Background technique [0002] The anti-slide pile is a beam member that penetrates the landslide body and is deeply embedded in the slide bed. Through the pile body, the thrust of the landslide on the upper part is transmitted to the soil or rock mass of the slide bed below the pile, and the pile is embedded in the slide bed rock. The lateral resistance of the soil balances the thrust of the sliding mass in the load-bearing section of the pile to achieve the effect that the reinforced slope is in a stable state. The main advantages of anti-slide piles are: strong anti-slide ability, clear force effect; flexible pile position, can be located in the most favorable part of the landslide bod...
