Description

Technical Field

[0001] This utility model belongs to the technical field of building construction, specifically, it relates to a tunnel lining trolley with adjustable brackets. Background Technology

[0002] Tunnel lining refers to the permanent structure that supports and maintains the long-term stability and durability of a tunnel. Its functions include: supporting and maintaining the stability of the tunnel; maintaining the space required for vehicle operation; preventing weathering of the surrounding rock; and mitigating the influence of groundwater. Currently, when a corbel structure for constructing flue slabs is installed inside the tunnel, the flue corbel is usually poured after the main arch lining has been constructed and formed.

[0003] Application No. CN202422662053.1 discloses a tunnel lining trolley with an adjustable corbel. By setting the pad block, a gap can be formed between the deformable part and the first template. When the deformable part is compressed, it can prevent it from contacting the first template. Alternatively, when the deformable part is compressed, the deformation generated can be transferred to the gap. This weakens the force of the deformable part pushing the first template upward, thereby effectively suppressing the deformation of the first template and improving the forming quality of the flue slab corbel. Although it has certain effectiveness, during the demolding operation, the construction workers first need to use a hammer to strike the template component 5 to create a gap between the template component 5 and the flue slab corbel concrete. Since the sealing block can only move horizontally under the action of the first hydraulic telescopic rod, and since the sealing block is in contact with the template component for support, the sealing block will limit the descent adjustment of the template component. When striking the template component, external force will be applied to the sealing block and the first hydraulic telescopic rod, causing the hydraulic telescopic rod to deform. In addition, the support components on the outside of the main frame are fixed to the bottom surface, and the repeated disassembly and assembly of the support components during the movement of the frame is inconvenient.

[0004] In view of this, this utility model is proposed. Utility Model Content
