Abstract

The invention relates to a water-gas mixing jet flow device used for sinking a pile, which comprises a pile body, a high pressure water pipe and a high pressure gas pipe. The water-gas mixing jet flow device is characterized in that the high pressure water pipe and the high pressure gas pipe extend into a high pressure jet flow mixing pipe at the bottom of the inner cavity of the pile body in parallel. The device is favorable for fully utilizing the kinetic energy of high pressure water and high pressure gas to flush the stratum layer so that sand pulp is formed and discharged, thereby the work efficiency for sinking the pile is improved.

Description

technical field [0001] The invention relates to a pile sinking water-air mixed jet equipment. Background technique [0002] The traditional water flushing and air lift assisted pile sinking method injects high-pressure water and high-pressure gas into the bottom stratum of the pile through water and air pipes. The existing problems are that the scour force is weak and the work efficiency is low. Contents of the invention [0003] The object of the present invention is to provide a water-air mixed jet equipment for pile sinking, which is beneficial to make full use of the kinetic energy of high-pressure water and high-pressure gas to scour the strata to form mortar discharge, thereby improving the work efficiency of pile sinking. [0004] The invention includes a pile body, a high-pressure water pipe and a high-pressure air pipe, and is characterized in that: the high-pressure water pipe and the high-pressure air pipe are merged into a high-pressure jet mixing pipe extendin...
