Pile tooth type anchorage and construction method thereof
The invention relates to a pile tooth type anchorage and a construction method thereof. The pile tooth type anchorage comprises a front anchorage chamber; an anchor plug body which is arranged behindthe front anchor chamber, and a steel strand used for being connected with a main cable is arranged in the anchor plug body; and a plurality of pile teeth which are used for being stressed together with the anchor plug body and are integrally arranged at the periphery of the anchor plug body. According to the pile tooth type anchorage and the construction method thereof, on the premise that the scale of the anchor plug body is not increased, the bearing capacity of the anchor plug body can be improved, the construction difficulty and risk are reduced, the anchorage engineering scale is reduced, the structural safety, stability and durability are all remarkably improved, and meanwhile, due to the arrangement of the pile teeth, under the condition that main cable tension is the same, the anchor plug body can be shortened, the section size can be reduced, and the manufacturing cost is reduced by 25% compared with a conventional tunnel anchor.
本发明涉及一种桩齿式锚碇及其施工方法，其包括：前锚室；及设于所述前锚室后方的锚塞体，所述锚塞体内设有用于与主缆连接的钢绞线；用于与所述锚塞体一同受力的多个桩齿，一体设置于所述锚塞体的四周。本发明涉及的一种桩齿式锚碇及其施工方法，可以在不增大锚塞体规模的前提下，提高锚塞体的承载能力，降低施工难度及风险，减小锚碇工程规模，结构安全性、稳定性、耐久性均显著提高，同时，由于设置了桩齿，在主缆拉力相同的条件下，锚塞体长度可缩短，断面尺寸可减小，造价较常规隧道锚降低25％。
