WANG LUNXIANG / SU SHENGWEI / QIAO WEILI / LYU KEPENG

The invention belongs to the technical field of pumped storage power stations, and particularly relates to a dam slope reinforcing device for a pumped storage power station. The device is reasonable in structural design and mainly comprises a reinforcing pad, an anchoring nail, a heat pipe protection pipe, a conical head, an anti-falling component and a heat pipe component, the heat pipe protection pipe, the conical head, the anti-falling component and the heat pipe component jointly form a reinforcing assembly, and the heat pipe protection pipe is conveniently and smoothly driven into a foundation of a dam slope of a pumped storage power station through the design of the conical head; due to the design of the anti-disengaging component, the heat pipe protection pipe is not prone to disengaging after being driven into a foundation, the heat pipe protection pipe can lock the position of the reinforcing pad, meanwhile, the heat pipe protection pipe can provide protection for the inserted heat pipe component, and the heat pipe component is not prone to damage in the using process; due to the design of the heat pipe components, soil is frozen in winter at the same time, a freezing area with stable freezing strength is formed below the grating area, a water rising channel is cut off, and the destructive influence of soil frost heaving on a dam slope foundation is eliminated.

本发明属于抽水蓄能电站技术领域，具体涉及一种抽水蓄能电站坝坡加固装置。本发明结构设计合理，其主要由加固垫、锚固钉、热管防护管、锥头、防脱构件和热管构件构成，其中热管防护管、锥头、防脱构件和热管构件共同构成加固组件，锥头的设计便于顺利将热管防护管打入抽水蓄能电站坝坡的地基，防脱构件的设计使得在热管防护管打入地基后不易脱离，热管防护管可以将加固垫的位置锁定，同时热管防护管可以为插入的热管构件提供防护，使得热管构件在使用过程中不易出现损坏；热管构件的设计使得土壤在冬季同时冻结，于格栅区的下方形成一个具有稳定冻结强度的冻结区，切断水分上升的通道，消除土壤冻胀对坝坡地基的破坏性影响。
