CHINT Leak monitoring for subway

A remedy scheme of water leakage in the deep foundation pit of a subway station is introduced. The deformation and axial forces of the supporting structure as well as the underground water level were monitored during the leaking prevention process. At the same time, a plane model was developed to simulate the construction process of foundation pit by FEM.

    Feb 07, 2007Manual ventilation without minute-ventilation monitoring seems to provide the least ventilatory stability. The use of a transport ventilator provides the best ventilatory consistency, but blood-gas changes have been reported when transport ventilators without monitoring of minute ventilation and exhaled tidal volume are used. 2,4,5,12,13

  • Geotechnical influence on existing subway tunnels

    Mar 01, 2014The manual monitoring points are distributed at the bottom of the up-line and down-line track beds. Measurement nails with smooth convex spherical tops are buried after drilling by an electric impact drill or nail gun, which produces distinct marks at the measurement points. The electronic level bar is employed in automated monitoring.
