Water sealing method for civil engineering groundwork

Abstract

The present invention discloses a water sealing method for a civil engineering groundwork, belonging to a water sealing technology field of the civil engineering, including the following steps: (A) according to a geology condition, forming pores in the stratum using a pore-forming machinery; (B) filling water sealing filler into the pore in sequence, attaching or pressing the filler into the stratum by a hammer, thus the water sealing filler is piled into the gap of the stratum or replaces the water seepage stratum, to form a water sealing pile around the pore; (C) redoing the steps (A) and (B) according to requirements, such that the neighboring water sealing piles are overlapped with each other or the water sealing pile is overlapped with other water sealing boundary to form a continuousenclosed water sealing belt to stop the groundwater from penetrating. The method of the invention has advantages of a simple construction, a reliable water sealing, and a low fabrication cost; it issuitable for various stratums, especially for a gravel layer, a fragmental stone layer and a pebble layer and has an obvious effect.

Description

Water-stopping method for civil engineering foundation technical field The invention relates to a water-stopping method for a civil engineering foundation, more specifically, it relates to a water-stopping method for a civil engineering foundation which is mainly used in the water-stopping construction of the side wall of the foundation pit or the construction of groundwater leakage plugging in the civil engineering. Background technique The current water-stopping methods for the side wall of the foundation pit in civil engineering mainly include the deep mixing pile method, the high-pressure jet method, the grouting method, the underground diaphragm wall method, and the steel sheet pile method. The deep mixing pile method is to mix and inject cement slurry or cement powder and soil to form piles while stirring, and to achieve the purpose of water stop by lapping piles. This method is simple in construction, widely used, and relatively expensive. But this method is only ...

AI Technical Summary

Problems solved by technology

It can be seen from the above that the conventional water-stopping methods have their own advantages and disadvantages. Except for the underground diaphragm wall method, none of them can solve the water-stopping problem of the gravel layer, crushed stone layer, and pebble layer. The water permeability of the gravel layer, crushed stone layer, and pebble layer Very large, often determines the success or failure of the project, and also has a great impact on the project cost

Although the underground diaphragm wall method can solve the problem, the cost of the underground diaphragm wall method is too high, and general construction units cannot accept it at all.
