Embodiment Construction

[0042] Such as Figure 1-12 As shown, the omni-directional water-tight structure of the submerged underground station in the confined water stratum is set in the area below the confined water surface 2; 4. The end surface 5 and the bottom surface 6; the all-round water-stop structure encloses the underground station 1 to be built in the space inside the box; two adjacent surfaces are connected to each other.

[0043] In this embodiment, auxiliary channels are respectively provided at both ends of the omnidirectional water-stop structure, and the auxiliary channels include vertical shafts 11 arranged at the front and rear ends of the underground station 1 to be built, and arranged above the front end and the rear end of the underground station 1 to be built. The transverse channel 12 and the construction channel 7 arranged below the transverse channel 12; wherein, the transverse channel 12 is located at the bottom side of the vertical shaft 11, and the horizontal channel 12 is ...

Abstract

The invention discloses an all-dimensional water stop structure for an underground station underground excavated in a confined water stratum and a construction method of the all-dimensional water stopstructure. The all-dimensional water stop structure for the underground station underground excavated in the confined water stratum is arranged in the area below the confined water surface; the overall all-dimensional water stop structure is in a box shape, and comprises a top face, longitudinal side faces, an end face and a bottom face; a to-be-built underground station is enclosed in a space ofthe box-shaped interior by the all-dimensional water stop structure; and every two adjacent faces are connected to each other. According to the all-dimensional water stop structure for the underground station underground excavated in the confined water stratum and the construction method of the all-dimensional water stop structure, the technical problem that traditional construction methods cannot completely satisfy the construction of large underground space in deep-buried water-rich stratums is solved.

Description

technical field [0001] The invention relates to the field of underground space construction, in particular to an all-round water-stop structure and a construction method for underground stations excavated in pressurized water strata. Background technique [0002] In the construction of traditional underground excavation stations, tube well precipitation and grouting are often used to treat groundwater. However, large amounts of precipitation can easily cause settlement deformation of the surface and surrounding structures and excessive exploitation of groundwater resources. With the improvement of environmental awareness, various regulations began to impose strict restrictions on groundwater exploitation. At the same time, subject to the effect of grouting and water-stopping and the strength requirements of underground large space construction, the existing technology cannot fully meet the needs of underground large space construction in deep water-rich strata. Therefore, a ...
