Abstract
In order to solve a series of problems arising from the installation of tunnel core pump house in the main tunnel of shield tunnel section,the current built-in pump house of tunnel core pump in existing lines in Tianjin was taken as an example.The overall layout of drainage pump was optimized.The depth of sump was increased by open-ing holes at the bottom of the pipe segment to meet the related requirements of drainage.The technology scheme of installing sumps sinking outside the pump house by mechanical method in the tunnel section was proposed to meet the demand of the effective volume of the sump.The longitudinal length of the sump was shortened to reduce the ad-verse effects on the ballast structure.The construction form,structure scheme and implementation steps of the spe-cial lining segment related to the implementation of the technology were put forward.The whole construction process of the technology was analyzed by numerical simulation.The results show that the overall construction risk of the technology is controllable and the structural scheme is reasonable.In view of the current demand of underground en-gineering construction,the technology scheme above researched has important exploration value and popularization significance.关键词
