Hanging and Top-down Construction of a Ventilation Shaft in Soft Soils

Abstract:

“Hanging and Top-Down” (HTD) Method of ventilation shaft construction Technology will be described in this paper. Using this method, the shield pass a more shallow ventilation shaft pit quickly just close beneath it, the tuyeres between the tunnel structure and the base slab of ventilation shaft pit are constructed later using a technology similar to “top-down method”, and the tuyeres hang at the base slab of the pit, no dewatering adopted during the construction. This paper will also address efforts at solving the problems the technology encountered, especially the method to control the deformation of tunnel structure.
