Technical Field
The utility model relates to a temporary blocking wall structure for a tunnel constructed by an open cut method.
Background
Along with the large number of construction of underground open cut tunnels, the crossing situation is more and more unavoidable, so that the construction time sequence difference between different tunnels can be generated, and interfaces are required to be reserved at the end parts of the tunnels and the positions of intersections; in addition, due to the requirements of construction conditions and construction progress, the tunnel can be subjected to sectional construction, so that temporary plugging is needed to be performed at the end part of the tunnel, at a reserved interface or at a sectional part, the safety and the integrity of a tunnel structure are ensured, and temporary plugging is removed when the tunnel is constructed to the position in the later stage, so that the whole tunnel is penetrated.
In order to facilitate connection on a later newly-built tunnel structure, temporary plugging of the tunnel is usually arranged at the deformation joint. At present, a temporary plugging structure for an underground open cut tunnel is mainly filled with flexible materials at the position of a buried water stop belt in the end part of the tunnel, the water stop belt is protected, and then a steel plate or cast concrete is used for plugging at the outer side of the plugging structure.
The disadvantage of this form of construction is that: a. the shutoff wall in tunnel tip outside can not effectually be connected with tunnel main part structure, and overall stability is poor. b. The flexible material filled in the water stop is easy to be extruded and deformed, so that the performance of the water stop is affected.
Therefore, in the existing temporary plugging structure, when plugging is performed, the integrity of the main structure is protected, but the sealing effect of the plugging structure is poor, and the waterproof effect is poor.
