Hole type spillway anchoring structure
The invention provides a tunnel type spillway anchoring structure which comprises a tunnel body anchoring part and a spillway anchoring part, the tunnel body anchoring part comprises a tunnel body supporting frame arranged at the joint of a tunnel body and a soil body, a plurality of first anchor rods are inserted into the tunnel body supporting frame, one end of each first anchor rod penetrates through the tunnel body supporting frame, and the other end of each first anchor rod extends into the soil body; a plurality of first slurry outlet holes are formed in the first anchor rod, and anchoring slurry is arranged in the first anchor rod; the hole face anchoring part comprises a hole face supporting frame and a plurality of second anchor rods, the hole face supporting frame is arranged at the joint of the hole face and the soil body, the second anchor rods are distributed at intervals along the outer side edge of the hole face supporting frame, and the second anchor rods are inserted into the soil body in the hole entering direction; a plurality of second slurry outlet holes are formed in the second anchor rod, and anchoring slurry is arranged in the second anchor rod. The spillway side wall and the top arch are anchored in the tunnel body, and the cement mortar is injected, so that the anchor rod and the soil body at the tunnel body are connected into a whole, and the structural strength of the side wall and the top arch of the tunnel body is guaranteed; meanwhile, a supporting frame is erected at the hole face and matched with an anchor rod, and soil loosening is prevented.
本发明提供了一种洞式溢洪道锚固结构，包括：洞身锚固部，包括设置在洞身和土体连接处的洞身支撑架，洞身支撑架上插设有多根第一锚杆，第一锚杆的一端贯穿洞身支撑架，另一端延伸至土体中；第一锚杆上开有若干个第一出浆孔，内部设有锚固浆；洞脸锚固部，包括设置在洞脸和土体连接处的洞脸支撑架以及多根第二锚杆，多根第二锚杆沿洞脸支撑架的外侧边沿间隔分布，第二锚杆沿进洞方向插设在土体中；第二锚杆上开有若干个第二出浆孔，内部设有锚固浆。本发明通过在洞身中锚固溢洪道侧壁以及顶拱，注入水泥砂浆，从而将锚杆和洞身处土体连接形成一体，保证洞身侧壁以及顶拱的结构强度；同时，在洞脸处架设支撑架，配合锚杆，防止土体松动。
