Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, in particular to a vault casting device for tunnel lining. Background Art

[0002] The arch pouring device for tunnel lining is usually used to pour concrete on the arch during tunnel construction. This device can help construction workers pour concrete at a high altitude inside the tunnel to ensure the integrity and stability of the arch structure.

[0003] However, in the prior art, in the existing arch pouring device for some tunnel linings, when workers are pouring, due to the different tunnel heights, they need to select a suitable length of the top pipe to adapt to the construction needs. After the selection, they are generally connected and fixed by components such as flanges and bolts during installation. This method can indeed stably install the pouring pipe and the top pipe, but due to shaking during use, a certain gap will be generated at the connection. The presence of the gap during pouring may cause concrete to leak into the connection, increasing the safety risks at the construction site. For example, concrete dripping may cause injuries to workers or equipment. Utility Model Content
