Bidirectional slurry supply hole internal circulation type contact grouting system and using method thereof
The invention discloses a bidirectional slurry supply hole internal circulation type contact grouting system, and relates to the field of water conservancy and hydropower engineering foundation treatment. The system comprises slurry inlet main pipes and a slurry return main pipe; slurry outlet boxes are arranged on each horizontal slurry inlet pipe at intervals; the horizontal slurry inlet pipes and horizontal slurry return pipes are connected through the slurry outlet boxes; and a horizontal slurry inlet pipe is led out of each slurry inlet main pipe in the elevation direction. According to the bidirectional slurry supply hole internal circulation type contact grouting system, slurry is fed from the upstream side and the downstream side, and the grouting guarantee rate is greatly increased; the slurry inlet main pipes are arranged on the upstream side and the downstream side, the slurry inlet main pipes and the slurry return main pipe in the middle form two loops, the whole contact grouting system is in a parallel network shape, it can be effectively guaranteed that a grouting pipeline can still normally operate under the condition that local blockage occurs, and the grouting guarantee rate is greatly increased. The invention further relates to a using method of the bidirectional slurry supply hole internal circulation type contact grouting system.
本发明公开了一种双向供浆孔内循环式接触灌浆系统，涉及水利水电工程基础处理领域。它包括进浆主管和回浆主管；水平进浆管上间隔布置有出浆盒；水平进浆管和水平回浆管之间通过出浆盒连接；进浆主管在高程方向上引出水平进浆管；本发明从上下游两侧分别进浆，极大地提高了灌浆保证率；本发明在上下游两侧均布置进浆主管，与中部的回浆主管构成两个回路，接触灌浆系统整体呈并联网络状，可有效保证灌浆管路在出现局部堵塞的情况下仍能正常运行，极大地提高了灌浆保证率。本发明还涉及这种双向供浆孔内循环式接触灌浆系统的使用方法。
