Constant-flow grouting control method for cement-soil mixing pile
The invention discloses a constant-flow grouting control method for a cement-soil mixing pile, which comprises the following steps of: determining a design flow through calculation according to a design index; setting sampling period time, and calculating period design flow in a sampling period; setting permissible deviation of periodic design flow; setting sampling times in a sampling period; sampling and calculating period effective flow and period effective pressure in a sampling period through a sampling data filtering algorithm, and collecting period effective frequency of a grouting motor at the same time; the period effective flow is calibrated, the setting constant K is measured, and the setting effective flow is obtained through calculation; judging whether the set effective flow is within an allowable deviation range or not; if not, the frequency of a grouting motor is adjusted; if yes, the frequency operation of the grouting motor is kept; and the next sampling period is continued until grouting is finished. Feedback control can be automatically and rapidly carried out according to the change of the pipeline flow, and accurate output of the cement slurry pipeline flow is achieved.
本发明公开了一种水泥土搅拌桩恒流量注浆控制方法，根据设计指标，通过计算确定设计流量；设定采样周期时间，并计算采样周期内的周期设计流量；设定周期设计流量的允许偏差；设定采样周期内的采样次数；通过采样数据滤波算法，在一个采样周期内，采样并计算周期有效流量和周期有效压力，同时采集注浆电机的周期有效频率；校准周期有效流量，测定整定常数K，计算得到整定有效流量；判断整定有效流量是否处于允许偏差范围内；若否，则调整注浆电机的频率；若是，保持注浆电机频率运行；继续下一个采样周期，直至注浆结束。本发明能自动根据管道流量的变化自动、快速进行反馈控制，实现水泥浆管道流量的精准输出。
