Construction plant for repairing and strengthening tunnel lining structures

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 that can automatically drive in a tunnel, and at the same time paste carbon fiber cloth in a circular direction on the tunnel lining structure and coat epoxy resin impregnated glue on the surface. Background technique [0002] Different degrees of cracks will appear in the tunnel lining structure during use, which will lead to various hazards such as lining leakage and erosion, 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 partially repair and reinforce the tunnel lining to restrain the crack expansion and ensure the safe operation of the tunnel. At present, methods such as spraying steel fiber concrete, supplementing concrete lining, and pasting steel plates are often used to treat tunnel l...

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...
