Mine dangerous rock mass grouting reinforcement device
Compared with the prior art, the mine dangerous rock mass grouting reinforcement device has the advantages that the vertical grouting grooves are formed in the tops of the child dangerous rock and the mother rock, the inclined grouting grooves are formed in the bottoms of the child dangerous rock, the vertical insertion pipes are inserted into the vertical grouting grooves, and the inclined insertion pipes are inserted into the inclined grouting grooves; the stud at the bottom of the vertical insertion pipe can be locked with the screw hole of the inclined insertion pipe, so that the three insertion pipes are locked between the sub dangerous rock and the mother rock, secondary locking connection is carried out through the internal insertion column and the inclined rod, and the stability after connection is enhanced to cope with the prestress of the sub dangerous rock; concrete grout is added into the vertical grouting grooves and the inclined grouting grooves through grouting holes in the surfaces of the vertical insertion pipes and the inclined insertion pipes, after solidification, the outer ends of the sub-dangerous rock and the mother rock are locked through peripheral fixing pieces, anchor ropes wind around fixing rings at the tops of the vertical insertion pipes and the inclined insertion pipes, and the prestress of the sub-dangerous rock is further reinforced from the periphery.
本发明提供一种矿山危岩体注浆加固装置，相对于现有技术，在子危岩和母岩顶部均开设有竖向注浆槽，子危岩底部在开设斜向注浆槽，并且在竖向注浆槽和斜向注浆槽内部分别插入竖向插管和斜向插管，竖向插管底部螺柱可以与斜向插管的螺孔锁定，从而三个插管在子危岩和母岩锁定，在通过内部的插柱和斜杆进行二次锁定连接，加强连接后的稳定性，来应对子危岩的预应力，通过竖向插管和斜向插管表面上的注浆孔向竖向注浆槽和斜向注浆槽内部加入混凝土浆液，待凝固后，子危岩和母岩外端通过外围固定件锁定，锚绳绕过竖向插管和斜向插管顶部的固定环，从外围进一步对子危岩的预应力进行加强。
