Description

Technical Field

[0001] The present application relates to the technical field of tunnel secondary lining casting, and in particular to a concrete casting window gate structure. Background Art

[0002] Tunnels are engineering structures buried in the ground and are a form of human use of underground space. Formwork casting trolleys are used to cast concrete in tunnels according to the different contours of the tunnel during tunnel construction. They are widely used in the construction of railways, highways, water conservancy and hydropower projects. The use of formwork casting trolleys can not only avoid construction interference and improve construction efficiency, but more importantly, it greatly improves the quality of lining construction in tunnels, while also improving the degree of mechanization of tunnel construction.

[0003] However, after the pouring is completed, the existing pouring structure needs to close the gate to seal the formwork working surface. Since the gate is located on the side of the formwork away from the tunnel wall, when the concrete solidifies, a bulge with the same thickness as the formwork will be formed on the tunnel wall; therefore, the above problem needs to be solved urgently.
