Grouting device and method for repairing subsidence section of frozen soil road
The invention discloses a grouting device and method for repairing a subsidence section of a frozen soil highway, and belongs to the technical field of roadbed repairing. The grouting device comprises a hole inlet pipe installed in a grouting hole and a fixing base detachably connected with the hole inlet pipe and installed at an orifice of the grouting hole, and the hole inlet pipe is provided with an input hole connected with a grouting mechanism; the device is characterized in that a rubber pipe is installed at the position, close to the fixing base, of the hole inlet pipe, an expansion space communicated with the interior of the hole inlet pipe is formed in the rubber pipe, an elastic piece capable of extending into the hole inlet pipe is installed on the fixing base, and the end, located on the inner side of the hole inlet pipe, of the elastic piece is fixedly connected with an extrusion plate; a plugging plate is slidably mounted in the hole inlet pipe in a limited mode, and during grouting, slurry drives the plugging plate to slide towards the side close to the extrusion plate so that the elastic piece can be compressed. In the grouting process, the density of the slurry is guaranteed, and the permeation effect of the slurry on the hole side base layer is improved.
本发明公开了一种用于冻土公路沉陷段修复的注浆装置及方法，属于路基修复技术领域，包括安装在注浆孔内的入孔管以及与入孔管可拆卸连接且安装在注浆孔的孔口处的固定座，所述入孔管设有与注浆机构连接的输入孔，其特征在于：所述入孔管靠近固定座处安装有橡胶管，所述橡胶管内设有与入孔管内部连通的膨胀空间，所述固定座上安装有能够延伸至入孔管内的弹性件，所述弹性件位于入孔管内侧的一端固定连接有挤压板，所述入孔管内限位滑动安装有封堵板，注浆时，浆料带动封堵板往靠近挤压板侧滑动以使弹性件压缩。本发明在注浆过程中，保证了浆料的密度，提高了浆料对孔侧基层的渗透效果。
