Description

Technical Field

Among them, the secondary lining of the tunnel is an important part in the construction process of the tunnel project, and the quality of the secondary lining of the tunnel determines the safety of the tunnel. Since the arc-shaped steel bars and longitudinal steel bars are large in size and elastic, they are prone to swinging during the installation process. For example, as shown in a simple trolley for tunnel waterproofing and secondary lining steel bar construction with Chinese patent application number CN202222008687.6, it is welded by square steel, round steel pipe and stainless steel patterned anti-skid steel plate, with rollers arranged at the bottom for the trolley to travel, the top construction platform is used for waterproofing and secondary lining steel bar construction, and the walking platforms on both sides are used for workers to assist the personnel above to carry out waterproofing and secondary lining construction. The space under the trolley meets the space for the reverse transportation of the tunnel primary support construction materials, which can effectively reduce the time for setting up scaffolding, the overall structure is stable, the construction safety is guaranteed, the cost is low, the manufacturing materials are relatively conventional, and it has certain economic benefits. The promotion and use can produce better results.
