In-hole pressure balancer for high-pressure jet grouting pile construction
The invention discloses an in-hole pressure balancer for high-pressure jet grouting pile construction, and aims to provide an in-hole pressure balancer for high-pressure jet grouting pile construction, which can effectively solve the problems that in the high-pressure jet grouting pile construction process, underground cement soil slurry emerges into a tunnel, the tunnel is polluted, the pressure of underground cement soil cannot be controlled, and the construction efficiency is improved. The in-hole pressure balancer for the high-pressure jet grouting pile construction solves the problem that the construction quality of a high-pressure jet grouting pile is affected due to the fact that the pressure is low. The slurry returning device comprises a slurry returning container, a closed inner cavity is formed in the slurry returning container, a rotary spraying pipe upper via hole is formed in the top of the slurry returning container, a slurry returning container mounting base is arranged at the bottom of the slurry returning container, a rotary spraying pipe lower via hole is formed in the slurry returning container mounting base, and a slurry discharging connector is further arranged on the side wall of the slurry returning container. The pressure detector is used for detecting the pressure in the closed inner cavity of the return pulp container; and one end of the slurry discharging pipe is connected with the slurry discharging connector in a sealing manner.
本发明公开了一种高压旋喷桩施工用洞内压力平衡器，旨在提供一种能够在不影响高压旋喷桩施工的情况下，有效解决在高压旋喷桩施工过程中，地下的水泥土浆液会冒出至隧道内，污染隧道的问题以及无法控制地下水泥土的压力，存在因压力偏低，而影响高压旋喷桩的施工质量的问题的高压旋喷桩施工用洞内压力平衡器。它包括回浆容器，回浆容器内具有密闭内腔，回浆容器的顶部设有旋喷管上过孔，回浆容器的底部设有回浆容器安装座，回浆容器安装座内设有旋喷管下过孔，回浆容器侧壁上还设有排浆接口；压力检测器，压力检测器用于检测回浆容器的密闭内腔内的压力；排浆管，排浆管的一端与排浆接口密封连接。
