Application
It is used for multi-pipe rotojet construction within the diameter of 142 of drill pipe. It can realize the operating requirements of self-rotation, high and low speed, traveling, rotojet and swing jet.
Introduction
HFDG-150 walking all rotary spray rig is on the basis of the traditional technology of high-pressure rotary jet grouting and adopted a unique porous pipe and the front pressure monitoring devices, realize the hole force in slurry and ground pressure monitoring, and by adjusting the forced pulp quantity to control internal pressure, significantly reduce the disturbance of the surrounding foundation;Its technological characteristics are horizontal, inclined, vertical and arbitrary Angle construction, large pile diameter and good pile quality.
Features
Suitable for multi-pipe rotojet construction within the diameter of 142 drill pipe;It can display mud volume, air volume, ground pressure, rotary speed, lifting speed, lifting distance, stepping distance, swing spray Angle, etc.Printing part: it can print instantaneous mud amount, accumulated mud amount, instantaneous grouting pressure, lifting speed, pressure inside the hole bottom, air pressure, air flow, water pressure of cutting hole and water flow of cutting hole.
