Technical Field

The invention belongs to the technical field of landslide prevention and control, and particularly relates to a miniature slide-resistant pile combined structure and a construction method thereof.

Background

The anti-slide pile penetrates through a landslide body and goes deep into a pile column of a slide bed, is used for supporting and blocking the sliding force of the landslide body and playing a role in stabilizing a side slope, is suitable for the landslide of a shallow layer and a medium-thick layer, and is a main measure for anti-slide treatment. When the anti-slide pile is used, piles (such as wood piles, steel piles, concrete piles or reinforced concrete piles) of different types can be selected according to the thickness, the thrust, the waterproof requirement, the construction condition and the like of a slide mass, and the slide mass with a small and medium area generally adopts a miniature anti-slide steel column. When an existing micro anti-sliding steel column is installed, concrete is simply used for pouring and fixing the micro anti-sliding steel column, so that the anti-sliding capacity of the micro anti-sliding steel column is general, and the micro anti-sliding steel column is prone to inclination when meeting slight slope landslide.

The micro pile with high rigidity can reduce the displacement deformation of the accumulation body and plays a role in resisting sliding, and the micro pile with low rigidity allows soil around the pile to deform to a certain extent and plays a role in reinforcing the accumulation body. And three miniature pile combination modes are designed, so that pile soil forms a complex with higher rigidity, which is equivalent to a large-scale anti-slide pile and jointly forms a whole to bear external load. The combined structure fully exerts the capability of the coordinated combined action of pile-soil deformation, has small disturbance on the rock-soil layer, but has a complex connecting structure, and is not beneficial to wide application.
