Ultra-large self-propelled tunnel multifunctional operation platform and construction method of tunnel steel bar waterproof plate

Abstract

The invention discloses an ultra-large self-propelled tunnel multifunctional operation platform. The operation platform is characterized in that a chassis is arranged below a disc buckle type support,the chassis is divided into a left chassis body and a right chassis body and is disconnected at the position of a vehicle passing door opening, a middle temporary lap joint frame is arranged below the vehicle passing door opening and used for lap joint of the left chassis body and the right chassis body to form an integral rigid frame, a travelling driving system is arranged below the chassis, anadjustable base can penetrate through the chassis to stretch to the ground to be supported, when the tunnel multifunctional operation platform moves, the adjustable base retracts and then is separated from the ground, a cantilever crane, winches and rollers are installed at the positions, at the top of the disc buckle type support, of the operation platform, the winch on the left side is combinedwith the rollers to lift lining steel bars on the right side, and the winch on the right side is combined with the rollers to lift lining steel bars on the left side. Meanwhile, the invention furtherdiscloses a construction method of a tunnel steel bar waterproof plate. According to the ultra-large self-propelled tunnel multifunctional operation platform, self-moving and reutilization can be achieved, stability and reliability are achieved in the using process, and the construction efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of engineering construction, and in particular relates to a self-propelled tunnel multifunctional work platform suitable for super-long-span tunnels, and a construction method for installing lining waterproof boards and steel bars using the self-propelled tunnel multifunctional work platform. Background technique [0002] Conventional tunnel reinforcement and waterproof board work benches are processed with section steel, which is costly, slow to install, has no power device, and requires other mechanical cooperation to walk. Manually dragging the reinforcement from the ground upwards is labor-intensive. If conventional methods are used for the super-large cross-section tunnel reinforced waterproof board work platform, it will be time-consuming, labor-intensive, costly, and inconvenient to walk. [0003] Currently known tunnels that require lining have a span of no more than 40 meters, and general road and r...

AI Technical Summary

Problems solved by technology

The super-long-span tunnel reinforced waterproof board work platform is generally constructed with full-wall brackets or Bailey beam brackets. After each bracket is erected and poured, it cannot be moved. It can only be dismantled and re-installed in a transferred position, which is time-consuming and labor-intensive. Manufacturing costs are high; especially For tunnels with tight construction schedules, a large number of platforms need to be invested, and the cost is very high. In addition, it is difficult to assemble in the tunnel
