Rotary spraying body pressure control method
The invention provides a jet grouting body pressure control method which comprises the steps that the top elevation H and the pressure control height L of a jet grouting pile are determined, a slurry outlet pipe of a stop-grouting plug is introduced into a temporary slurry storage container with the elevation larger than L + H, and the outlet elevation of the slurry outlet pipe is L + H; a waste slurry discharge pipe is arranged at the lower part of the temporary slurry storage container, and waste slurry is discharged into a waste slurry container; and the pressure control height L is adjusted, so that effective slurry in the consolidation range does not flow out when the jet grouting pile is implemented. The problem that slurry flows out during upward inclined jet grouting is ingeniously solved, the jet grouting technology can be applied to the field of horizontal and upward jet grouting operation and is particularly important for consolidation of broken rock masses and soil layers under tunnels and other special conditions, the application range of the jet grouting technology is greatly expanded, and the application range of the jet grouting technology is widened. More importantly, the pressure of the rotary spraying body can be stably and accurately controlled and adjusted; the method is high in controllability, small in risk, convenient to implement and low in implementation cost, and the quality of the implemented rotary spraying structure is good.
本发明提供了一种旋喷体压力控制方法，步骤包括：确定旋喷桩顶部标高H和压力控制高度L，将止浆塞的出浆管引入标高大于L+H的临时储浆容器中，出浆管的出口标高为L+H；在临时储浆容器下部设置废浆排放管，将废浆排放到废浆容器中；调整压力控制高度L，使旋喷桩实施时固结范围内的有效浆体不流出。本发明巧妙地解决了向上仰斜旋喷时浆体外流的问题，使旋喷技术可以应用到水平和向上旋喷作业的领域，对于隧道和其它特殊情况的破碎岩体和土层固结尤其重要，大大拓展了旋喷技术的应用范围，更关键的是能够稳定、准确地控制和调节旋喷体压力；本发明可控性强、风险小、便于实施，实施成本低，实施后的旋喷结构质量好。
