Grouting method for simultaneously recovering tunnel settlement and horizontal deformation
The invention discloses a grouting method for simultaneously recovering tunnel settlement and horizontal deformation, which comprises the following steps of: calculating positions and grouting amounts of vertical grouting and inclined multi-point grouting through numerical simulation software, and respectively forming a vertical grouting hole and a plurality of inclined grouting holes in corresponding positions of each ring segment; preparing a first grouting device and a second grouting device; second grouting devices are inserted into the vertical grouting holes, and first grouting devices are inserted into the inclined grouting holes correspondingly; a foundation pit is excavated on the inner side of the underground diaphragm wall, monitoring equipment in a tunnel is observed, and if a certain annular pipe piece generates displacement and deformation, grouting is conducted in the grouting pipes in the vertical grouting holes and the inclined grouting holes in the positions corresponding to the annular pipe piece; after the grout is solidified, vertical grouting bodies and multiple point grouting bodies are formed, monitoring equipment is continuously observed in the grouting process, and grouting is stopped when the horizontal displacement, the vertical displacement and the ovality of the tunnel are restored to set values. By adopting the method, the tunnel vertical rigid body displacement recovery rate is close to 1.
本发明公开了一种同时恢复隧道沉降及水平变形的注浆方法，步骤为：通过数值模拟软件计算竖向注浆和斜向多点注浆的位置及注浆量，每一环管片相对应位置处分别设置一个竖向注浆孔和多个斜向注浆孔；准备第一注浆装置和第二注浆装置；在竖向注浆孔中插入第二注浆装置，在斜向注浆孔中分别插入第一注浆装置；在地连墙内侧开挖基坑，观察隧道内监测设备，若某一环管片产生位移和形变，则向与该环环管片对应位置处的竖向注浆孔和斜向注浆孔内的注浆管内注浆；浆液凝固后形成竖向注浆体与多个点注浆体，注浆过程中持续观察监测设备，待隧道水平位移、竖向位移、椭圆度恢复到设定值时，停止注浆。采用本方法隧道竖向刚体位移恢复率接近1。
