The method of chiseling and taking out the pile body of the cast-in-situ pile

Abstract

The invention relates to the technical field of cast-in-place piles, and discloses a gouging-out and removing method of a pile body of a cast-in-place pile. The gouging-out and removing method comprises the following steps that (1), construction is carried out between a middle portion pile and an outer ring pile to form a vertically-arranged outer ring groove around the middle portion pile, the middle portion pile and the outer ring pile are separated by the outer ring groove, the middle portion pile is provided with a plurality of crossed grooves, the crossed grooves communicate with the outer ring groove, the middle portion pile is divided into middle portion pile blocks by the crossed grooves and the middle portion pile blocks are gouged out and transported to the outside; (2), partition seams are constructed in the outer ring pile, the outer ring pile is divided into a plurality of outer ring pile blocks by the partition seams, and stirrups and stiffeners are cut off; (3), dividingseams are constructed at the bottom of the outer ring pile, exposed main reinforcements are cut off, and the outer ring pile blocks are transported to the outside; and (4) the steps (1)-(4) are repeated, the pile body is downwards broken down layer by layer until the defects of the pile body are gouged out and transported to the outside, the middle portion pile and the outer ring pile are gougedout and transported to the outside very conveniently, the pile body is removed section by section, the construction efficiency is high and the construction cost is low.

Description

technical field [0001] The invention relates to the technical field of cast-in-situ piles, in particular to a method for chiseling and removing pile bodies of cast-in-place piles. Background technique [0002] During the construction of cast-in-situ piles, due to improper operation of the process, common quality problems such as pile concrete separation and pile breakage are prone to occur. Re-construction, filling piles and other methods to deal with. [0003] At present, when the defect position of the pile body is deeply buried or the section is large, the grouting method is difficult to effectively guarantee the treatment quality, and the secondary inspection and maintenance time is long; the rework construction is carried out on the original pile position, because the concrete strength of the pile body is high and the reinforcement If the content is large, percussion drilling takes a long time and costs high, and the impact is carried out with mud, and the construction...
