Pebble bed grouting reinforcement device and method
The invention discloses a pebble bed grouting reinforcement device and method, and belongs to the technical field of grouting reinforcement. The grouting head structure comprises a grouting outer pipe, an upper end plate and a lower end plate are arranged at the upper end and the lower end of the grouting outer pipe respectively, a through hole is formed in the middle of the upper end plate, a connecting sleeve is arranged in the middle of the inner side face of the lower end plate, a grouting inner pipe is arranged in the connecting sleeve, one end of the grouting inner pipe is connected into the connecting sleeve, and the other end of the grouting inner pipe is connected into the connecting sleeve. The other end of the grouting inner pipe penetrates out of the through hole of the upper end plate, a plurality of grout outlet holes are formed in the end, located in the grouting outer pipe, of the grouting inner pipe, an upper annular groove and a lower annular groove are formed in the outer side face of the lower end of the grouting outer pipe, and a mounting distance is formed between the upper annular groove and the lower annular groove. An upper annular sealing air bag and a lower annular sealing air bag are arranged in the upper annular groove and the lower annular groove respectively. The technical scheme is used for improving the grouting reinforcement effect of the pebble bed.
本发明公开了一种卵石层注浆加固装置及方法，属于注浆加固技术领域。所述注浆头结构包括注浆外管，所述注浆外管的上端和下端分别设有上端板和下端板，所述上端板的中部设有通孔，所述下端板的内侧面中部设有连接套筒，所述连接套筒内设有注浆内管，所述注浆内管的一端连接于连接套筒内，所述注浆内管的另一端穿出上端板的通孔设置，所述注浆内管位于注浆外管内部的一端上设有若干出浆孔，所述注浆外管的下端部外侧面上设有上部环形凹槽和下部环形凹槽，所述上部环形凹槽和下部环形凹槽之间设有安装间距，所述上部环形凹槽和下部环形凹槽的内部分别设有上部环形密封气囊和下部环形密封气囊。本技术方案用以提升卵石层的注浆加固效果。
