Sleeve valve pipe grouting structure and grouting replacement method thereof
The invention relates to the technical field of underground engineering and hydraulic engineering, and discloses a sleeve valve pipe grouting structure which comprises a sleeve valve pipe and a grouting pipe, the grouting pipe is located in the sleeve valve pipe, the head of the grouting pipe is provided with a front-end grout stop ring and a rear-end grout stop ring, and the front-end grout stop ring and the rear-end grout stop ring are arranged at intervals. A grout outlet is formed between the front end grout stop ring and the rear end grout stop ring, a sleeve valve grout outlet is formed in the sleeve valve pipe, and a sleeve valve is arranged on the sleeve valve grout outlet. The grouting replacement method of the sleeve valve pipe grouting structure mainly comprises the following steps that 1, the distance between the front end grout stop ring and the rear end grout stop ring on the grouting pipe is adjusted; 2, displacement slurry is injected from the grouting pipe at high pressure, and grouting is stopped when the displacement slurry appears; 3, a stop-grouting plug is placed in a hole opening of the grouting hole; and 4, the grouting pipe is moved, and segmented high-pressure grouting is conducted. The method is suitable for high-pressure grouting in an unstable soil body, and the overall strength of a solid and the plugging capacity of a water body are improved.
本发明涉及地下工程及水利工程技术领域，公开了一种袖阀管注浆结构，包括袖阀管和注浆管，所述注浆管位于袖阀管内，注浆管的头部设有前端止浆圈和后端止浆圈，前端止浆圈和后端止浆圈间隔布置，前端止浆圈和后端止浆圈之间设有浆体出口，袖阀管上设有袖阀出浆孔，袖阀出浆孔上设有袖阀。袖阀管注浆结构的注浆置换方法，主要包括以下步骤，1、调整注浆管上的前端止浆圈和后端止浆圈的距离；2、从注浆管中高压注入置换浆体，见置换浆体出现时，停止注浆；3、在注浆孔的孔口放入止浆塞；步骤4、移动注浆管，进行分段高压注浆。适用于不稳定的土体中高压注浆，加固体整体强度和水体的封堵能力。
