Continuous wall rock-socketed wall forming system and method

Abstract

The invention discloses a continuous wall rock-socketed wall forming system and method. The continuous wall rock-socketed wall forming system comprises a pile frame, a power assembly, a drill rod anda drilling tool, and the power assembly drives the drilling tool through the drill rod; the drilling tool is a bundled down-the-hole hammer and comprises a carrier and a plurality of down-the-hole hammer bodies arranged on the carrier, the projection area of the carrier is rectangular, the width of the projection area is the same as the width of a continuous wall trench, and the down-the-hole hammer bodies are distributed in a matrix mode; when a hard rock stratum construction section is encountered, the bundled down-the-hole hammer is used for drilling, the rock stratum can be smashed, a square groove can be formed in each time of operation, and the bundled down-the-hole hammer continuously operates and can rapidly form a groove. Each down-the-hole hammer is one of common tools for rock stratums, the advantages of the down-the-hole hammer bodies for excavating the rock stratums are utilized, the down-the-hole hammer bodies are bundled and then applied to a grooving system of a continuous wall, the price cost is effectively reduced, and the operation efficiency is high.

Description

technical field [0001] The invention relates to a continuous wall, in particular to a continuous wall rock-socketed wall-forming system which utilizes a down-hole hammer to form grooves. Background technique [0002] In the urban subway construction, the underground diaphragm wall technology is widely used in the foundation pit support system. Traditionally, the underground diaphragm wall construction technology is suitable for softer geology by using pile punching machine to assist groove forming machine to construct underground diaphragm wall. In the construction of underground diaphragm walls under the geological conditions of moderately weathered and slightly weathered rocks, such as hard rocks and thick rock formations, problems such as partial holes and slow punching will inevitably occur during construction, resulting in low construction efficiency, delays in construction period, and diaphragm wall bulges and steel cages. Card cage and other quality problems. At pres...

Problems solved by technology

In the construction of underground diaphragm walls under the geological conditions of moderately weathered and slightly weathered rocks, such as hard rocks and thick rock formations, problems such as partial holes and slow punching will inevitably occur during construction, resulting in low construction efficiency, delays in construction period, and diaphragm wall bulges and steel cages. Card cage and other quality problems

At present, if the rock is hard and the rock layer is thick, the underground continuous wall is usually constructed by using a double-wheel milling machine, but the disadvantage of the double-wheel milling machine is that it is expensive
