Antiskid pile with outer isosceles trapezoid cross section and in unequal interval arrangement

Abstract

The invention relates to an antiskid pile with an outer isosceles trapezoid cross section and in unequal interval arrangement. The antiskid pile is formed by pouring reinforced concrete, the cross section of the antiskid file is an outer isosceles trapezoid, rebar cages are mounted in the antiskid pile, dense rebars are arranged in the rebar cage on one side at the rear end of the pile, and few rebars are arranged on one side at the front end of the pile. The antiskid pile adopts an unequal interval arrangement method to form a pile interval arrangement layout with a dense middle and two sparse sides, namely the antiskid piles arranged close to a main slide section with large landslide thrust are small in pile interval, and the pile interval at sections on two sides of a landslide is gradually increased according to progressive decrease of the landslide thrust. The antiskid pile can bear bigger landslide thrust and has excellent anti-bending performance, and the size of the cross section of the antiskid pile is evidently smaller than that of an antiskid pile with a rectangular cross section, so that cubic amount of concrete pouring and rebar using amount can be greatly reduced, and cost is lowered. The antiskid pile with the outer isosceles trapezoid cross section and in unequal interval arrangement is small in construction section, convenient for mechanical construction, safe and simple in construction and wide in popularization and application prospect.

Description

technical field [0001] The invention relates to a construction method of reinforced concrete anti-slide piles used in side slope engineering and landslide control engineering, in particular to a construction method of outer isosceles trapezoidal cross-section anti-slide piles arranged at unequal intervals, belonging to the side Stabilization technical field for slopes or slopes. Background technique [0002] Setting anti-slide piles is a very widely used method for controlling slopes or landslides. The effect of anti-slide piles on landslides is to use the resistance (anchor force) of anti-slide piles inserted into the stable stratum below the sliding surface to balance the slide. The thrust of the body increases its stability. When the landslide body slides down, it is resisted by the anti-slide pile, so that the slide body in front of the pile reaches a stable state. In landslide and slope treatment projects, only when the anti-slide piles are arranged in a certain numbe...
