High-pressure jet grouting device for civil engineering
The invention discloses a high-pressure jet grouting device for civil engineering. The high-pressure jet grouting device comprises a drill rod, wherein the lower end of the drill rod is rotatably connected with the top side of a coaxial round box through a sealed bearing; the top side of the round box is open; first jet holes are separately formed in the left side and the right side of the inner wall of the round box; the inner wall of the lower end of the drill rod is fixedly connected with the periphery of a coaxial first inner tube; a coaxial vertical shaft is arranged in the first inner tube; the lower end of the vertical shaft is fixedly connected with the bottom of the round box; first spiral blades are fixedly mounted on the upper part of the periphery of the vertical shaft; and theperiphery of each first spiral blade is in sliding contact fit to the inner periphery of the first inner tube. The high-pressure jet grouting device is simple in structure and skillful in concept, and a spray head is driven to rotate or swing by kinetic energy generated by spraying flow, so that energy consumption generated by rotation or swing of the drill rod along with the spray head is avoided, and therefore, energy consumption can be reduced; and moreover, different jet modes can be freely exchanged, so that market needs can be met, and the high-pressure jet grouting device is suitable for being popularized.
土木工程用高压喷射注浆装置，包括钻杆，钻杆的下端通过密封轴承转动连接同轴的圆盒的顶侧，圆盒的顶侧开口，圆盒内壁的左侧与右侧分别开设第一喷射孔，钻杆下端的内壁固定连接同轴的第一内管的外周，第一内管内设有同轴的竖轴，竖轴的下端与圆盒的底部固定连接，竖轴外周的上部固定安装第一螺旋叶片，第一螺旋叶片的外周与第一内管的内周滑动接触配合。本发明结构简单，构思巧妙，利用喷浆流动产生的动能带动喷头转动或摆动，从而避免钻杆随喷头转动或摆动产生的能耗，能够节省能耗，并能够自由调换不同的喷射方式，能够满足市场需求，适合推广。
