Underground water control method during construction of water-sealed cave depot

The invention provides an underground water control method during water-sealed cave depot construction, and relates to the technical field of water-sealed cave depot construction. According to the control method, advanced water detection work serves as a guide, the underground water state of a to-be-excavated section is analyzed and judged, then an excavation grouting scheme is determined on the basis, the scheme comprises the steps of selecting grouting time and materials, monitoring underground water of a cave depot site and tracking leakage points at the same time in the whole excavation process, and the underground water state of the to-be-excavated section is determined through the thought of a system theory. The technical result and the construction effect are closely associated, overall arrangement is conducted on excavation work on the whole, it is guaranteed that underground water is not lost in the construction period, and finally the water seal pressure during cave depot operation is guaranteed. 本发
