Abstract

The invention discloses a water collecting well, a counter-slope tunnel and a counter-slope tunnel drainage method. The water collecting well is applied to the counter-slope tunnel, the water collecting well comprises a pump station cavern, a drainage pump is installed in the pump station cavern, and the drainage pump is used for lifting water in the water collecting well to another water collecting well; the pump station cavern is arranged in a comprehensive cavern of the counter-slope tunnel and / or a side wall cavern of an auxiliary pilot tunnel of the counter-slope tunnel; and the side wallcavern is formed by excavating the side wall of the auxiliary pilot tunnel of the counter-slope tunnel in the direction perpendicular to the axis of the counter-slope tunnel. According to the technical scheme, the technical problem that in the prior art, the safety is low in the water collecting well construction process is solved.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to a water collection well, a reverse slope tunnel and a drainage method for the reverse slope tunnel. Background technique [0002] When the tunnel is being constructed in a water-rich area, the amount of groundwater will be large after the tunnel is excavated, and the construction of the tunnel with drainage along the slope is relatively less difficult, but the construction difficulty will be greatly increased in the tunnel construction where long-distance reverse slope drainage construction is required. [0003] In the past long-distance reverse slope drainage construction, it is usually adopted to set up fixed relay pumping stations, pump water step by step, and finally discharge it to the outside of the tunnel. The pumping station is adopted to relay step by step, and then the wastewater in the tunnel is discharged to the outside of the tunnel. In the existing rever...
