More Information
Summary:A lining segment for water pressure control of a high-burial depth water-rich stratum TBM-method inclined shaft comprises a segment body, a grouting hole and an inverted arch road surface, wherein a water-draining pressure relief hole is formed on the segment body. According to the lining segment, when the pressure of water at the back of the segment reaches 0.3Pa, water draining and pressure relief can be conducted automatically, so that the impact of groundwater pressure on the lining segment can be controlled effectively during construction of the TBM-method inclined shaft, the load borne by the lining segment is reduced, the service life of the segment is prolonged, and the safety and the stability of the construction are improved.
