Pile foundation sediment cleaning device and method
The invention provides a pile foundation sediment cleaning device and method. The pile foundation sediment cleaning device comprises a high-pressure jet grouting pile foundation device, a gas-liftingreverse circulation device and an air compressor. A high-pressure jet grouting pile machine performs continuous punching by the aid of high-pressure gas to separate mud from sediment, and relatively small particles of the sediment are returned through holes; then holes are cleaned through gas-lifting reverse circulation, gas-lifting reverse circulation means that compressed air is supplied into aduct via an air pipe to form a negative-pressure area, relatively-thick particles of the sediment are returned through a pouring duct, and a circulation system is formed. According to the device, thesediment is dispersed by the aid of the impact force produced by the high-pressure gas, the ideal effect can be achieved in the short time, the mud can be separated from the sediment, the working efficiency can be substantially improved, the construction quality can be guaranteed, the construction cost can be saved, and the construction operation surface can be accurate, so that other soil bodiesare not disturbed, the hole collapse probability is reduced, the hole forming construction scientificity and reasonability are guaranteed, and the disturbance to the nearby pile foundation soil body is considered as much as possible.
本发明提供一种桩基沉渣清理装置及其方法，该桩基沉渣清理装置包括高压旋喷桩基装置、气举反循环装置和空压机。高压旋喷桩机利用高压气体连续冲切，使泥与沉渣分离，通过孔口返送颗粒较小沉渣；再通过气举反循环进行清孔，气举反循环是压缩空气经风管向导管内送风，形成负压区，通过浇筑导管返送颗粒较粗沉淀物，并形成循环系统。该装置通过高压气体所产生的冲击力将沉渣冲散，能在短时间内达到理想效果，使泥与沉渣分离开，工作效率得以大幅提升，保证施工质量与节约施工成本，能精确的施工作业面，从而不对其它土体的扰动，降低塌孔概率，确保成孔施工的科学性及合理性，最大化的考虑对附近桩基土体的扰动。
