Embodiment Construction

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0019] see figure 1 , the present invention provides a waterproof structure for civil engineering expansion joints, the construction process is as follows: (A) using a hole-forming machine to form holes in the ground; The water-stop filling material is driven into the ground to form a water-stop pile; (C) Repeat steps (A) and (B) as required to make the water-stop piles overlap each other or the water-stop pile overlap with other water-proof boun...

Abstract

The invention discloses a waterproof structure for civil engineering expansion joints, and belongs to the technical field of water stop in civil engineering. The waterproof structure is characterizedby comprising the following steps: (A) forming a hole in a stratum by using a pore-forming machine according to geological conditions; (B) sequentially loading water-stopping fillers into the hole, and hammering or pressing the water-stopping fillers into the stratum by a hammer, and squeezing the water-stopping fillers into gaps of the stratum or replacing a water seepage stratum to form a water-stopping pile around the hole; and (C) repeating the operation of steps (A) and (B) as needed to make the adjacent water-stopping piles be in overlap butt with each other or make the water-stopping piles be in overlap butt with other water-resisting edges to form a continuously closed water-stopping belt, so that the purpose of preventing groundwater seepage is achieved. The method disclosed by the invention has the advantages of simple construction, reliable water stop and low construction cost, is suitable for various strata, and has remarkable effects in water stopping construction especially in a gravel layer, a rubble layer and a pebble layer.

Description

technical field [0001] The invention relates to a water-stopping method for a civil engineering foundation, more specifically, it relates to a waterproof structure for expansion joints in civil engineering mainly used in the water-stopping construction of the side wall of the foundation pit of the civil engineering or the construction of groundwater leakage plugging. Background technique [0002] 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. [0003] 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 suitable for soft soil and loose or ...
