Description

High-pressure triple-pipe rotary spraying grouting equipment

Technical Field

The application relates to the field of engineering construction equipment, in particular to high-pressure triple-pipe rotary spraying grouting equipment.

Background

At present, in modern construction, a high-pressure jet grouting technology is generally adopted in engineering projects such as seepage prevention, reinforcement and the like. The high pressure jet grouting technology is mainly applied to soft soil layers, and is characterized by adopting drilling, extending a grouting pipe provided with a special alloy nozzle into a preset position, then using a high pressure water pump or a high pressure mud pump to jet water or slurry out through the nozzle to impact and destroy soil bodies, enabling soil particles to be stirred and mixed with the slurry and rearranged according to a certain rule under the comprehensive actions of the impact force, the centrifugal force, the gravity and the like of a jet flow beam, and forming a solidification body with a certain shape in the soil after the slurry is solidified.

The high-pressure jet grouting is divided into three types, namely single-pipe rotary spraying, double-pipe rotary spraying and triple-pipe rotary spraying, and different equipment is selected according to different processes. The device adopted in the triple-pipe rotary spraying method can refer to Chinese patent with publication number CN205171496U, and discloses a high-pressure rotary spraying grouting device for foundation reinforcement, which comprises a machine body, wherein a triple-pipe body is connected to the machine body in a sliding manner, the top end of the triple-pipe body is connected with a driving mechanism fixedly connected with the machine body, the bottom end of the triple-pipe body is connected with a drill bit, high-pressure cement paste, an air mixed liquid nozzle and a high-pressure water and air mixed liquid nozzle are distributed on the side wall of the bottom of the triple-pipe body, the high-pressure water and air mixed liquid nozzle is positioned above the high-pressure cement paste and air mixed liquid nozzle, and a high-pressure water, air and high-pressure water cement paste storage tank is connected with the top end of the triple-pipe body through a conveying pipeline. When the device is used, the driving mechanism drives the triple pipe body to descend, the drill bit drills holes, the triple pipe body extends into a preset position, then high-pressure water, air and high-pressure cement paste in the storage tank are conveyed to the nozzle through the triple pipe body, the driving mechanism drives the triple pipe body to rotate, the high-pressure cement paste, air mixed liquid, the high-pressure water and air mixed liquid are sprayed out from the nozzle in a rotating mode, and soil bodies are damaged. The resistance that receives when the rotation of triple pipe body and drill bit trompil all can make triple pipe body take place to rock thereby lead to the position of punching to take place the skew, consequently can connect a horizontally deflector on the organism usually, has seted up the through-hole on the deflector, and triple pipe body passes the through-hole, and the deflector not with triple pipe body butt to play the guide effect to triple pipe body.

The inventor considers that: the triple pipe body of the in-process that punches and destroy the soil body takes place to rock, can make to take place the rigidity contact between triple pipe body and the deflector, causes the pit to bump triple pipe body, and long-term use can make triple pipe body take place to damage, has reduced the life of triple pipe body.

SUMMERY OF THE UTILITY MODEL

In order to reduce the possibility that triple pipe body collided with to improve the life of triple pipe body, this application provides a high pressure triple pipe rotary spray grout equipment.
