A super-large-diameter overall mobile metal formwork for shafts

Abstract

The invention discloses a super-large-diameter overall movable metal formwork for a shaft, which includes a standard formwork, a lifting drive device, a deformation-preventing pre-embedded pressing mechanism and a demoulding mechanism. The anti-deformation pre-embedded pressing mechanism is installed on the standard formwork and the anti-deformation pre-embedded pressing mechanism is used to press the suspension ear plate of the formwork, and the demoulding mechanism is installed between two adjacent standard formworks. And the two adjacent standard formworks are demoulded or supported to open the mold under the action of the demoulding mechanism. This application can realize the synchronous lifting and lowering of the formwork by the lifting drive device or multiple ground stabilizer (winch) steel wire rope lifting points, and enhance the overall rigidity of the formwork and the ability to resist local deformation through the anti-deformation pressing device. It becomes smaller or larger within the elastic range, and can quickly complete the demoulding, lowering (or raising), vertical formwork pouring and other processes, saving the time for masonry well walls.

Description

technical field [0001] The invention relates to the technical fields of vertical shaft construction in municipal, mining, hydropower and the like. Specifically, it is a large-diameter integral mobile metal formwork for a shaft. Background technique [0002] With the continuous advancement of global climate change and urbanization, problems such as insufficient capacity of urban water diversion and drainage systems and low drainage standards have become increasingly prominent. Events such as urban rainstorms, waterlogging and overflow pollution occur frequently, which not only cause serious damage to road traffic and residents' travel. Difficulties have also caused disasters such as black and odorous downstream water bodies, which seriously threaten the development of the city and the safety of people's lives and properties. The urban deep water diversion and drainage tunnel, as a large pipeline drainage system buried deep underground, has a large discharge capacity and stor...
