Description

Technical Field

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

[0002] As the highway network extends to mountainous and hilly areas, highway tunnels are characterized by being long, large, and deeply buried. Tunnel ventilation shafts are also getting larger and deeper, and many new problems have emerged during the shaft construction process. In order to improve the mechanization level of highway tunnel ventilation shaft construction and improve the safety and quality of shaft construction, more and more ventilation shaft secondary linings are constructed using the slipform casting method. The slipform casting construction method is one of the templates used when pouring cement concrete. It can gradually slide along the horizontal direction, slope direction, or vertical direction, so that it can be demoulded while pouring. It is an economical and advanced method. Shaft slipform casting is a casting method that slides in the vertical direction.

During the casting process, the shaft at the circumferential position needs to adjust the overall position of the pump pipe according to different casting conditions. The pump pipes of the existing casting devices are mostly adjusted by manual pushing. Due to the limited thrust of humans, the overall casting position of the pump pipe cannot be effectively determined according to work requirements. Utility Model Content
