Fastening method of post-treating pipe pile break with pre-stress pipe pile construction

Abstract

The invention relates to a reinforcing method for dealing with the rupture of a pipe pile after the construction of the prestressed pipe pile. The procedures are as following: (1) the position of the rupture of the prestressed pipe pile is detected first; (2) the laitance on the inner wall of the pipe pile is cleared; (3) a reinforced skeleton frame is put into the pipe pile and the reinforced skeleton extends to the position three meters under the pipe pile from the pile top; (4) concrete under pile level is poured into the pipe pile, and the strength grade is not smaller than C30; (5) after the condensation of the concrete, the reinforced skeleton frame is led to be fixed with the reinforced steel in a cushion cap, and further the reinforced technique of the rupture of the pipe pile is finished. The reinforcing method of the invention can ensure the safety of the structure and does not affect the construction of the next working procedure; besides, the invention has the advantages of convenient construction, short constructing period, low cost and good effect.

Description

Technical field [0001] The invention relates to a prestressed pipe pile construction method, in particular to a reinforcement method for treating the fracture of the prestressed pipe pile after construction. Background technique [0002] During the construction of the pile foundation, if there are broken pipe piles found on site, the original pile machine can be used to fill the piles. If the broken pipe pile is detected after the pile machine is removed, the pile machine will not be allowed to enter again after the excavation of the construction site For construction operations, only reinforcement and reinforcement measures can be taken. At present, the method of pile reinforcement is generally adopted. Manual digging is used to dig to the fracture of the pile body. The upper pile is manually cut out, and the steel cage is used for straightening. This is more troublesome and cumbersome, and the construction period is prolonged, which is not conducive to the smooth progress of th...

Problems solved by technology

[0002] During the construction of the pile foundation, if there is a broken pipe pile found on the site, the original pile machine can be used to repair the pile. If the pile machine is removed and the broken pipe pile is found through inspection, the pile machine will not be allowed to enter after the construction site is excavated. For construction work, only reinforcement measures can be taken in this way. At present, the method of pile connection is generally used for reinforcement, in the form of manual digging, digging to the fractured part of the pile body, and the upper section of the pile is manually chiseled out, and the reinforcement cage is used to straighten the pile. , which is more troublesome and cumbersome, and the construction period is prolonged, which is not conducive to the smooth progress of the project, and the compaction effect of the soil around the pile is weakened. The displacement of the soil around the pile to the hole will cause the original pile to deviate, and the retaining wall will be displaced or even collapsed. Obviously Does not meet the needs of today's construction industry
