Self-service wall protecting device and wall protecting method for cast-in-situ bored pile
The invention provides a self-service wall protecting device and method for a cast-in-situ bored pile, and belongs to the technical field of cast-in-situ piles. The self-service wall protection device of the cast-in-situ bored pile comprises a guniting assembly and a cleaning assembly. The guniting assembly comprises an energy supply part, an anti-blocking part and a hole inlet part, and the anti-blocking part and the hole inlet part are both arranged on the energy supply part. During use, secondary slurry spraying is performed on the retaining wall, the drill bit and the drill rod are taken out of the hole, the drill bit and the hole are staggered, then the third valve and the first valve are closed, the second valve is opened, the water pump works, the water pump injects clean water into the mud guide hose through the first water guide pipe and the second water guide pipe, and the clean water flushes out slurry in the mud guide hose and the drill bit. According to the self-service wall protecting device and method for the cast-in-situ bored pile, the situation that the mud guide hole is blocked by large impurities in mud is effectively prevented, the hole opening efficiency is improved, and better use experience is brought to a user.
本发明提供了钻孔灌注桩的自助护壁装置及护壁方法，属于灌注桩技术领域。该钻孔灌注桩的自助护壁装置包括喷浆组件和清洗组件。所述喷浆组件包括供能部、防堵部和进孔部，所述防堵部和所述进孔部均设置在所述供能部上。使用时，对护壁进行二次喷泥浆，把钻头和钻杆从孔洞取出后，把钻头与孔洞错开，然后关闭第三阀门和第一阀门，打开第二阀门，水泵工作，水泵通过第一导水管和第二导水管把清水注入到导泥软管内，清水把导泥软管和钻头内的泥浆冲出，该钻孔灌注桩的自助护壁装置及护壁方法有效的防止泥浆内的大杂质堵塞住导泥孔的情况出现，提高了开孔洞的效率，给使用者带来更好的使用体验。
