Backfill grouting pipe for geotechnical engineering construction
A plurality of grouting holes b are formed in the outer surface of an inner pipe, a connecting piece is arranged at the upper end of the inner pipe, the lower end of the inner pipe is closed and connected with a threaded connecting block, a limiting baffle is arranged at the upper end of the outer portion of the inner pipe in a sleeving mode, and two blocking connecting rings are arranged in the middle and the lower end of the outer surface of the inner pipe in a sleeving mode correspondingly. A groove is formed in the outer part of the plugging connecting ring; the outer pipe is located below the limiting baffle and slidably arranged outside the inner pipe in a sleeving mode, a plurality of grouting holes b are formed in the surface of the outer pipe, supporting blocks and limiting rings are arranged on the two end faces of the grouting holes b correspondingly, guide blocks are arranged on the inner sides of the supporting blocks, clamping grooves are formed in the inner sides of the guide blocks, one end of the connecting rod is located in the clamping grooves, and springs are arranged between the end of the connecting rod and the bottom faces of the clamping grooves. A plugging block is concentrically and fixedly connected to the other end of the limiting ring and is in contact with the limiting ring; the conical limiting block is detachably connected with the threaded connecting block through a screw groove in the upper surface of the conical limiting block. The device has the advantages of being reasonable in structure and convenient to disassemble and clean.
本发明涉及一种岩土工程施工用回填土注浆管，其中内管外表面设有多个注浆孔b，且内管的上端设有连接件，下端封闭并连有螺纹连接块，限位挡板套设于内管外部的上端，两个封堵连接环分别套设于内管外表面的中部和下端，且封堵连接环的外部设有凹槽；外管位于限位挡板下方，并滑动套设于内管的外部，且外管的表面设有多个注浆孔b，注浆孔b的两端面分别设有支撑块和限位环，支撑块的内侧设有导向块，且导向块的内侧设有卡槽，连接杆一端位于卡槽内，并与卡槽的槽底面之间设有弹簧，另一端同心固定连有封堵块，且封堵块与限位环接触；锥形限位块通过其上表面的螺槽与螺纹连接块可拆卸连接；本发明具有结构合理且拆卸及清理操作便捷的优点。
