Karst geological cast-in-place pile quality defect repairing grouting assembly and construction method

Abstract

The invention discloses a karst geological cast-in-place pile quality defect repairing grouting assembly and a construction method. The karst geological cast-in-place pile quality defect repairing grouting assembly comprises a grouting pump, and further comprises a grouting pipe (1), a grouting plug (2) and a grouting hose (3), wherein one end of the grouting plug (2) is detachably connected with the grouting pipe (1), lifting lugs (4) are symmetrically arranged on the outer wall of the inlet end of the grouting pipe (1), and the end part of the outlet end of the grouting pipe (1) extends to be provided with a slurry outlet nozzle (5); and the other end of the grouting plug (2) is detachably connected with the grouting hose (3), and the grouting hose (3) is connected with the grouting pump. The method is simple and easy to implement, the construction period of repairing the quality defect of the cast-in-place pile is short, the influence on the construction period of the whole project is not large, the influence on the construction period can be reduced to the minimum through reasonable construction arrangement, and the repairing construction cost is low; and compared with a conventional treatment method, the process is simple in equipment and simple and easy to implement.

Description

technical field [0001] The invention relates to a grouting component and a construction method, in particular to a grouting component and a construction method for repairing quality defects of karst geological cast-in-place piles, which are mainly used to improve the quality of pouring piles in karst areas, and belong to underground engineering plugging , Reinforcement technology field. Background technique [0002] Generally speaking, with the acceleration of urban development and construction and the gradual development and utilization of underground space, the amount of construction waste is increasing year by year. According to estimates, in recent years, the annual output of construction waste in my country has reached hundreds of millions to billions of m 3 , Zhengzhou alone produced 100 million m of muck in 2015 3 , the annual output of muck in Shenzhen is 50 million m 3 above. At present, the phenomenon of illegal dumping and discharge of muck is very prominent; ...

AI Technical Summary

Problems solved by technology

[0008] Aiming at the many defects and deficiencies in the above-mentioned background technology, a karst geological cast-in-place pile quality defect repairing grouting component and construction method of the present invention have been improved and innovated, and the purpose is to provide a simple structure, flexible installation, and improved efficiency. To ensure the quality, it can not only reduce the construction cost, but also reduce the quality and safety hazards. At the same time, it can also effectively prevent the quality problems such as segregation of concrete due to excessive drop when pouring piles, so as to ensure the construction quality and reduce economic losses. Complete pouring of cast-in-situ piles under the premise of ensuring the quality of concrete
