Description
Technical Field
The utility model relates to the technical field of slope slide resistance, in particular to a novel reinforced concrete slide-resistant pile.
Background
Landslide is a geological disaster which is most widely distributed and seriously damaged in the form of slope damage, so that the problem of slope reinforcement is inevitably involved in civil and architectural engineering. The reinforced concrete slide-resistant pile in the existing slope reinforcement project has the advantages of strong slide resistance, small masonry quantity, flexible pile position, high concrete strength, strong bending resistance, crack resistance and corrosion resistance of a pile body and the like, and is widely applied to the project. In fact, the slide-resistant piles mainly resist the sliding of the soil body behind the upper sliding soil layer piles, and the soil body between the piles mainly shares the pressure to the soil body behind the piles by means of the soil arch effect and indirectly acts on the slide-resistant piles. The anti-slide pile transmits the pressure on the upper part to the lower stable soil layer. The soil arch effect is formed by reducing the compression deformation space of the soil body behind the circular pile, so that mutual 'wedging' action is generated among soil particles. The arc-shaped section of the anti-slide pile is beneficial to the generation of the soil arch effect, the pressure borne by the pile body is mainly transferred to the lower stable soil layer, and the soil body in front of the pile does not need to form the soil arch effect to transfer the pressure. However, the main cross-sectional form of the current slide-resistant pile is still round or square, and the problem to be improved exists. All the side surfaces of the anti-slide pile with the circular section adopt the arc surface shape, so that the waste of reinforced concrete resources is caused; the square section slide-resistant pile does not adopt an arc surface shape, so that the effect of the soil arch effect in the slide resistance of the pile body is weakened.
