The invention discloses an orifice pipe sealing device, a grouting device and a grouting method, and belongs to the technical field of water conservancy and hydropower construction. The orifice pipe sealing device comprises an orifice pipe, an upper supporting plate, a lower supporting plate and a stress transmission structure, and the stress transmission structure connects the upper supporting plate with the lower supporting plate; and the grouting device comprises the orifice pipe sealing device and further comprises a sleeve and an anti-drawing structure, and the anti-drawing structure comprises a barrel, two ejector rods, a clamping base, a jacking spring and a limiting rod. According to the orifice pipe sealing device, the grouting device and the grouting method, the lower supportingplate is connected with the upper supporting plate through the stress transmission structure, and the lower supporting plate is limited by the upper supporting plate and cannot move, so that downwardconstraint force is applied to a soil layer, and ground upheaval and pipeline deformation are prevented; and meanwhile, the grouting pressure can be improved and the grouting amount can be increased advantageously, the diffusion and reinforcement range of grout is expanded, the number of drilled holes is decreased, and the reinforcement effect is improved.
本发明公开了一种孔口管封固装置、注浆装置及注浆方法，属于水利水电施工技术领域。其中，孔口管封固装置，包括孔口管、上支撑板、下支撑板和受力传递结构，所述受力传递结构连接上支撑板和下支撑板；注浆装置包括所述的孔口管封固装置，还包括套管和抗拉拔结构，抗拉拔结构包括筒体、两根顶杆、卡座、顶紧弹簧和限位杆。本发明公开的孔口管封固装置、注浆装置及注浆方法中，下支撑板通过受力传递结构与上支撑板连接，并且下支撑板受到上支撑板的限制其位置不会移动，从而对土层施加向下的约束力，防止地面隆起以及管道变形，同时可有利于提高注浆压力和注浆量，扩大浆液的扩散和加固范围，节省钻孔数量，提高加固效果。
