Construction device and construction method for existing expressway soft foundation treatment technology
The invention discloses a construction device and a construction method for an existing expressway soft foundation treatment technology, and relates to the technical field of road and bridge soft foundation treatment. A rib is arranged on the outer wall of a grouting pipe of the device, and a stabilizing assembly of the device comprises a base plate and a guide ring. The base plate is erected on arotary jet grouting assembly, a through hole is formed in the base plate, and the guide ring is rotatably installed in the through hole. The guide ring is provided with a matching notch, the inner wall of the guide ring is sunken in the radial direction to form the matching notch, and the matching notch extends in the axial direction of the through hole and penetrates through the two end walls ofthe guide ring. A first ball used for being attached to the wall face of the side, away from the grouting pipe, of the rib is rotationally embedded in the bottom wall of the matching notch, and second balls used for being attached to the wall faces of the two sides of the rib are rotationally installed on the side walls of the two sides of the matching notch. The second balls are movably connected with and provided with an elastic assembly used for pushing the second balls to be tightly attached to the rib in the direction perpendicular to the wall face of the side wall of the matching notch.The stability of the grouting pipe in the operation process is effectively improved.
一种用于既有高速公路软基处治技术的施工装置及施工方法，涉及路桥软基处治技术领域。装置的注浆管的外壁设有筋条，其稳定组件包括基板和导环。基板架设于旋喷注浆组件，基板开设有通孔，导环可转动地安装于通孔。导环具有配合缺口，配合缺口由导环的内壁沿其径向凹陷形成，配合缺口沿通孔的轴向延伸并贯穿导环的两端端壁。配合缺口的底壁可转动地嵌设有用于同筋条的远离注浆管的一侧壁面贴合的第一滚珠，配合缺口的两侧侧壁可转动地安装有用于同筋条的两侧壁面贴合的第二滚珠。沿垂直于配合缺口的侧壁壁面的方向，第二滚珠活动连接并配置有用于推动其贴紧筋条的弹性组件。其有效地提高了注浆管在运转过程中的稳定性。
