Intelligent grouting control method for limestone geology
The invention relates to the technical field of formation grouting control, and particularly discloses an intelligent grouting control method for limestone geology, which is specially used for grouting anti-seepage treatment of easy-to-split limestone geology, and comprises the following steps of: determining an open grouting liquid ratio, determining a grouting control stage, and determining a slurry pressure PN and a flow span QnNm of a single control stage; and grouting step by step and ending grouting. The grouting control process method is more accurate, more stable and small in fluctuation, and a corresponding accurate pressure value and an accurate flow control target value are determined for each section of control step of grouting control. When special conditions are encountered in the grouting process, for example, stratum splitting is encountered in the grouting process, the newly developed grouting control process method can quickly make adjustment, detect that grouting is in a large-flow and low-pressure state, adjust the control steps in time, and return to the previous control stage or restart to control grouting from the initial stage.
本申请设计地层灌浆控制技术领域，具体公开了一种用于灰岩地质的智能灌浆控制方法，专用于易劈裂灰岩地质灌浆防渗处理，包括下述步骤：确定开灌浆液比,确定灌浆控制阶段，确定单一控制阶段的浆液压力PN及流量跨度QnNm；逐级灌浆和结束灌浆的步骤。该灌浆控制过程方法更加精准、更加平稳、波动小，为灌浆控制的每一段控制步骤确定了对应的一个准确压力值和准确的流量控制目标值。灌浆过程中遇到特殊情况时，如在灌浆过程中遇到地层劈裂，新研发的灌浆控制过程方法可以迅速作出调整，检测到灌浆处于大流量低压力的状态，及时调整控制步骤，重新回到上一个控制阶段或者从起始阶段重新开始控制灌浆。
