Construction method of ecological cutting system of cast-in-place pile

Abstract

The invention relates to a construction method of an ecological cutting system of a cast-in-place pile. The construction method comprises the following steps that 1) steel bar cages are arranged, andconcrete is poured; 2) a shearing plate is arranged; 3) a unit type expansion isolation system and a pressure sensor are arranged; 4) the concrete fills the tops of cast-in-place piles; 5) a crushingagent is injected; 6) the cast-in-place pile is cut off and constructed; and 7) the cutting section of the cast-in-place pile is hoisted. The construction method has the beneficial effects that the on-site prefabricated unit type expansion isolation system is adopted, not only can the accurate positioning of the pile cutting position of the cast-in-place pile be achieved, but also the steel bars and the concrete at the outer sides of the steel bars can be separated from the concrete at the inner sides of the steel bars simultaneously, and the difficulty of hoisting of the pile cutting construction and pile body section pile sections is lowered. According to the construction method, the shearing plate is preset at the cut-off position of the cast-in-place pile, so that shear force can be applied to the pile body; and the shearing plate acts together with the crushing agent, so that the efficiency of pile cutting construction is improved.

Description

technical field [0001] The present invention relates to a construction method for bored cast-in-situ pile cutting, in particular to an ecological pile-cutting system for bored piles that can reduce the difficulty of on-site pile cutting construction, improve the positioning accuracy of cut piles, and improve the efficiency of hoisting and construction of pile cut sections. The construction method belongs to the field of geotechnical engineering and is suitable for the construction engineering of bored piles. Background technique [0002] With the rapid development of engineering construction in my country, bored piles are widely used due to their high bearing capacity, strong applicability, and low engineering cost.

Problems solved by technology

This method presets the casing, which will affect the concrete pouring; at the same time, the post-grouting pipe is required, and the site construction efficiency is low; Effective constraint of the pile head

[0004] In summary, although the existing construction has achieved good construction results under suitable working conditions, there are still deficiencies in reducing the impact of construction on the environment, improving the effect of pile cutting, and improving the efficiency of on-site construction.
