Problems solved by technology

When the prestressed anchor cable is installed on the pile body, due to the high cost of the anchor cable and the cumbersome construction process, the prestress of the anchor cable will easily cause relaxation loss with the increase of time, and the material used is mainly steel bars, which often fail due to steel bar corrosion. The reliability of landslide or slope treatment engineering is obviously insufficient

Abstract

The invention discloses an anti-slide pile with supporting rods and a construction method thereof. The invention discloses an anti-slide pile with a supporting rod, the anti-slide pile comprises a circular upright pile body and a circular inclined supporting rod, the circular inclined supporting rod is connected to one side of the circular upright pile body, and the included angle between the circular upright pile body and the circular inclined supporting rod is 30-45 degrees. The anti-slide pile has the beneficial effects that the anti-pressure capability of a stable stratum and the load-bearing and anti-slide functions of the inclined supporting rods are fully exerted in combination with a stress mode of the anti-slide pile, and the bending resistance and the shear resistance of the anti-slide pile are improved; the construction method adopting the rotary drilling machine for dry-method hole forming has the advantages of being low in noise, low in vibration, high in hole forming speed, free of slurry circulation and the like. The structure has the advantages of high construction speed, small structural size, high bearing capacity, good anti-seismic property and the like.

Description

technical field [0001] The invention relates to an anti-sliding structure design aimed at the sliding surface or potential sliding surface of a landslide, in particular to an anti-sliding pile with support rods and a construction method thereof. Background technique [0002] In geotechnical engineering, rock and soil mass will produce sliding deformation under the action of various factors such as additional load, self-weight, water, earthquake and so on. In order to reduce these deformations, some anti-slip structures will be adopted. Among them, anti-slide pile support measures are widely used in landslide treatment and slope protection engineering because of their advantages such as high rigidity, good self-stabilization performance, convenient construction, and obvious reinforcement effect. [0003] In the current single pile design of anti-slide piles, the pile body is usually a straight pile structure, and the comprehensive utilization of the rock and soil mass before...
