Abstract

The invention provides a power head device for high-pressure spraying and grouting and a working method of the power head device. The device comprises a speed changing box, two motors, a multi-pipe drilling spraying rod, a flow divider, a multifunctional nozzle, a drill bit, a rotary spraying and swinging spraying device and a control system, wherein the rotary spraying and swinging spraying device comprises a chuck, an induction sheet, a probe bearing disc, an induction probe and a rotary spraying and swinging spraying main body part; the speed changing box and the motors have combined action through bolt connection and inner gear or belt connection. The working method comprises the following steps: putting equipment in position and setting parameters, starting rotary spraying or swinging spraying, pulling out the multi-pipe drilling spraying rod and the like. According the device and the working method, provided by the invention, all technical parameters can be accurately controlled, the rotary spraying and the swinging spraying can be simply and conveniently switched and the swinging spraying at any angle can be realized.

Description

technical field [0001] The invention relates to a power head device and a construction method for high-pressure jet grouting, which belong to the field of construction engineering. Background technique [0002] In recent years, with the acceleration of China's urbanization process, more and more underground spaces have been developed in first-tier cities. The existing underground structures are becoming more and more dense, the underground structures are complex, and there are more and more special projects. The foundation pit engineering has brought great challenges. The existing power heads for high-pressure grouting have the following disadvantages: one is that the power is too small; Technical parameters cannot be precisely controlled. Contents of the invention [0003] The invention provides a power head device for high-pressure jet grouting and its construction method. Two motors are used to provide power in synergy, and a computer control system is added to accura...
