Problems solved by technology
However, because the cohesion of the soil below the water level is greatly reduced, it cannot provide sufficient anchoring force for the pile foundation, and the reinforcement capacity of traditional anti-slide piles in the water level fluctuation zone is significantly reduced.
Tests have proved that the reinforcement effect of traditional anti-slide piles is significantly weakened under the condition of water level fluctuations, and it is prone to instability

Embodiment Construction
[0023] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.
[0024] Such as figure 1 and figure 2 As shown, the present invention is an L-shaped anti-slide pile used for water level fluctuations to strengthen soil slopes, including a number of L-shaped piles 4 formed by connecting a section of vertical piles and a section of horizontal piles, and the vertical piles are located above the horizontal piles .
[0025] In one form of the present invention, the vertical pile includes a vertical section reinforcement cage 41 filled with concrete, the horizontal pile includes a horizontal section reinforcement cage 42 filled with concrete, and the vertical section reinforcement cage 41 and the horizontal section reinforcement cage 42 outer surroundings are poured with retaining wall concrete 43.
[0026] According to the test analysis of soil slope reinforced by traditional anti-slide piles under the conditio...

The invention discloses an L-shaped anti-sliding pile used for reinforcing a soil slope under water level fluctuation. The pile comprises multiple L-shaped pile bodies formed through connection of a segment of vertical pile and a segment of horizontal pile, wherein the horizontal pile is poured into a base body of a landslide in the direction perpendicular to a side slope, and the lower end of thevertical pile is connected with the outer end of the horizontal pile, sequentially penetrates through the base body and a slip crack face from bottom to top and goes deep into a sliding body. The invention further provides a construction method of the L-shaped anti-sliding pile used for reinforcing the soil slope under water level fluctuation. According to the stress characteristics of the L-shaped anti-sliding pile used for reinforcing the soil slope under water level fluctuation, a traditional anti-sliding pile is improved, and the reinforcing effect and stability of the anti-sliding pile under the water level fluctuation condition can be improved.
Description
technical field [0001] The invention belongs to the technical field of water conservancy construction, and relates to soil slope reinforcement under the condition of water level fluctuations, in particular to an L-shaped anti-slide pile used for reinforcing soil slopes in water level fluctuations and a construction method thereof. Background technique [0002] Water level fluctuations are very likely to affect the stability of slopes and are an important cause of landslides. For example, after the Three Gorges Reservoir was impounded in 2003, the water level changed significantly, which significantly changed the hydrogeological environment of the slope in the reservoir area. Landslides will often occur, and the water level change of the reservoir is the main factor leading to landslides. In order to prevent landslide disasters, tools such as anti-slide piles, retaining walls and geotextiles were used to reinforce the slope. Among them, the anti-slide pile is a commonly used...
