Pile tooth type tunnel anchorage
The invention relates to the technical field of tunnel anchorage, and discloses a pile tooth type tunnel anchorage which comprises a mountain body and an upper anchor chamber, the bottom face of the upper anchor chamber is fixedly connected with a lower anchor chamber, when the pile tooth type tunnel anchorage is used, the interior of the mountain body is excavated before the tunnel anchorage is built, the space of the anchorage and pile teeth is reserved, and the anchor body and the pile teeth are arranged in the pile tooth type tunnel anchorage. When the lower anchor chamber is constructed, if a mountain body is loosened, when a main steel cable pulls a secondary steel cable through a cable saddle, the secondary steel cable pulls a connecting cable, then the connecting cable pulls a pulling fixing seat and drives a pulling column to move towards the lower anchor chamber at the same time, and meanwhile the pulling column pulls a pulling plate to contract towards the lower anchor chamber; and then the first supporting rod and the second supporting rod expand outwards at the same time, so that the stress area of the whole reinforcing device is increased, meanwhile, the loose mountain can be compacted, and the situation that when the mountain is loosened too much, the main steel cable pulls the lower anchor chamber through the secondary steel cable, and consequently the whole lower anchor chamber deforms and breaks down is prevented.
本发明涉及隧道锚碇技术领域，且公开了一种桩齿式隧道锚碇，包括山体、上锚室，所述上锚室的底面固定连接有下锚室，该桩齿式隧道锚碇在使用时，在隧道锚碇修筑前对山体的内部进行挖掘，预留出锚碇以及桩齿的空间，当下锚室修筑完毕时，如果发生山体松动的情况，当主钢索通过散索鞍拉动次钢索时，次钢索被拉动时会拉动连接索，进而使连接索拉动拉动固定座同时带动拉动柱向下锚室内移动，同时拉动柱会拉动拉动板向下锚室的方向收缩，进而使支杆一与支杆二同时向外扩张，从而增加整个加固装置的受力面积，同时会对松动的山体进行压实，防止山体松动过大时，主钢索通过次钢索拉动下锚室而导致整个下锚室变形崩坏。
