Grouting equipment for fault fracture rock mass in geotechnical engineering
The invention belongs to the technical field of fractured rock mass reinforcement, and provides geotechnical engineering fault fractured rock mass grouting equipment which comprises a grouting pipe and a pressing plate arranged at the front end of the grouting pipe, the pressing plate is elastically connected with the grouting pipe, a flexible surface layer is connected to the pressing plate, and the flexible surface layer is matched with the pressing plate to block a gap between the grouting pipe and the inner wall of a rock hole; an adjusting ring is slidably connected to the outer wall, away from the pressing plate, of the grouting pipe, a first flexible part is arranged on the adjusting ring, the first flexible part has a first state and a second state which can be switched, when the first flexible part is in the first state, the adjusting ring slides relative to the grouting pipe, and when the first flexible part is in the second state, the adjusting ring is fixed to the inner wall of the rock hole; a plurality of grouting holes are formed in the grouting pipe, and the grouting holes are selectively plugged by the plugging piece through the adjusting ring; and the second flexible part is arranged in the grouting hole, the second flexible part is provided with an output end, the output end is of a valve body structure, and the output end is used for improving the grouting pressure. The grouting effect can be improved.
本发明属于裂隙岩体加固技术领域，提出一种岩土工程断层裂隙岩体注浆设备，包括注浆管，设置在注浆管前端的压板，压板与注浆管弹性连接，压板上连接有柔性面层，柔性面层与压板配合以封堵注浆管与岩孔内壁之间存在的间隙；注浆管远离压板的外壁上滑动连接有调节环，调节环上设置有第一柔性件，第一柔性件具有可切换的第一状态和第二状态，当第一柔性件为第一状态时，调节环相对于注浆管滑动，当第一柔性件为第二状态时，调节环与岩孔内壁固定；注浆管上开设有若干注浆孔，封堵件通过调节环有选择的将注浆孔封堵；第二柔性件，设置在注浆孔内，第二柔性件具有一输出端，输出端为阀体结构，输出端用于提高注浆压力。本发明能够提高注浆效果。
