Construction equipment for repair and reinforcement of tunnel lining structure

Abstract

The invention relates to a construction plant for repairing and strengthening tunnel lining structures. The construction plant is characterized by comprising a running gear, any ring construction device (1 to 8) required in the invention, a lifting device with a lifting platform, a control device for controlling the construction plant to work and a driving device for driving a supporting arm to rotate. The lifting device is installed on the running gear; the ring construction device and the driving device are both installed on the lifting platform; and the control device is installed on the running gear. The construction plant has the beneficial effects that the construction flow is mastered through the plant, the automatic degree is high, a person does not need to enter a tunnel for construction, and the labor cost is saved; the mechanized construction quality is higher than the manual construction quality, coating of epoxy resin glue is even, a carbon fiber sheet is tightly and smoothly bonded, and the repairing and strengthening effect and the construction efficiency are guaranteed; and the construction plant is suitable for repairing and strengthening construction of the tunnel lining structures in different sizes, suitable for construction under various weather conditions and engineering environments and good in engineering adaptability.

Description

technical field [0001] The invention belongs to the technical equipment field of tunnel lining construction, and in particular relates to a walking construction equipment which can automatically drive in a tunnel, and simultaneously paste carbon fiber cloth circumferentially on the tunnel lining structure and coat the surface with epoxy resin impregnating glue. Background technique [0002] The tunnel lining structure will have different degrees of cracks during use, which will lead to various hazards such as water leakage and erosion of the lining, weaken the bearing capacity and durability of the tunnel lining structure, and affect the normal use of the tunnel. In view of these situations, it is necessary to locally repair and reinforce the tunnel lining to restrain the crack propagation and ensure the safe operation of the tunnel. At present, the treatment of tunnel lining cracks often adopts methods such as spraying steel fiber reinforced concrete, making up concrete lin...

AI Technical Summary

Problems solved by technology

[0004] At present, the reinforcement construction of carbon fiber composite materials mostly adopts the method of manual pasting. For the reinforcement construction of the inner wall of the tunnel, due to the small construction space, the construction is difficult for workers, and the construction quality and construction efficiency cannot be guaranteed; There is a threat to safety; because the inner contour of the tunnel lining structure is circular, it is not conducive to the paste of carbon fiber cloth

The repair and reinforcement project of the tunnel lining structure not only has a long construction period, but also has poor construction effect

There is no mature solution for the reinforcement of carbon fiber composite materials for cracks in the lining structure of small and medium diameter tunnels
