Technical Field

[0001] The utility model relates to the technical field of tunnels, in particular to a tunnel and a water-blocking structure inside the tunnel. Background Technique

[0002] When a tunnel is constructed through a water-rich stratum, sudden water inrush accidents are likely to occur. When a large amount of water inrush begins to enter the tunnel, the time for construction workers to evacuate the site will enter the countdown. Without water-blocking facilities, the water inrush quickly fills the construction working face, which may cause construction workers to be unable to evacuate in time and result in casualties.

[0003] In the prior art, when encountering such problems, reinforced concrete straight walls are usually adopted inside the tunnel. The wall height is 2 - 3m, which are staggered on the left and right halves of the tunnel. The longitudinal spacing between two adjacent reinforced concrete straight walls is 50 - 100m, used to block the water inrush from the heading face, slow down the water flow velocity, and buy precious time for construction workers to evacuate the site. However, such a structure brings inconvenience to the construction processes such as the binding and installation of steel bars, the preparation and pouring of concrete, the erection and removal of formwork, and curing. Moreover, the reinforced concrete straight walls need to be demolished after construction, so the cost is relatively high, resulting in the inability to popularize this method.
