Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction devices, in particular to a curved surface finishing device for the secondary slab concrete of a shaped water diversion tunnel. Background Art

[0002] Tunnel construction is a complex undertaking involving many aspects. First, a geological survey is required to determine the tunnel's route, depth, and structure. This process utilizes specialized equipment such as drilling rigs and rangefinders. This on-site exploration provides information about the strata, providing a basis for subsequent design. Next, the tunnel design phase is required. Based on the geological conditions and transportation requirements, a suitable tunneling solution is designed, including excavation methods, support structures, and drainage systems.

[0003] During the secondary lining construction of small-section water diversion tunnels, the traditional process of finishing the curved surface of the bottom plate is usually done manually using an iron trowel to level it. The finishing effect depends on the workers' technical level and is often not ideal. Specifically, it is manifested in large errors in the curvature of the finishing surface and poor surface finish and flatness of the concrete surface. At the same time, the cost of manual finishing is high. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] This utility model facilitates manual advancement of the device by providing a curved trowel and handrails, thereby enabling the concrete surface to be formed in one go. Compared to traditional manual curved finishing using an iron trowel, this significantly reduces the workload of workers, achieves better forming results, and precisely controls the curvature. Three attached vibrators are positioned equidistantly above the curved trowel. Buffer springs are provided to ensure close contact between the curved trowel and the concrete surface. Vibration is controlled by a manual switch, resulting in a dense bond between the concrete and the surface, eliminating honeycombing and roughness on the finished concrete surface, resulting in a mirror-like finish.
