Summary:The invention discloses a water pressure control method for use in TBM (Tunnel Boring Machine) method construction of a heavy-gradient high-burial-depth water-rich stratum inclined shaft. The method comprises the following steps of: 1, performing advanced geological forecast by using an advanced geological forecast system arranged on a TBM before TBM tunneling construction, and judging the position of a water-resisting layer in front of TBM construction; 2, performing underground water pre-discharge construction by drilling holes with an advanced detection/slip casting drilling machine; 3, performing slip casting behind a lining segment in a TBM tunneling construction process, and filling gaps caused by excavation construction behind the segment to initially prevent hydraulic communication; and 4, forming water drainage and pressure release holes on the lining segment, and automatically performing water drainage and pressure release construction when the water pressure behind the lining segment is up to 0.3MP
