Embodiment Construction

[0029] like figure 1 and figure 2 As shown, a large-diameter integral mobile metal formwork for a shaft includes a standard formwork 100, a lift drive device 200, an anti-deformation pre-embedded pressing mechanism 300 and a demolding mechanism 600. The lift drive device 200 is connected to all the The standard formwork 100 is drivingly connected, and the adjacent standard formwork 100 is detachably connected. The anti-deformation pre-embedded pressing mechanism 300 is installed on the standard formwork 100 and is pressed by the anti-deformation pre-embedded pressing mechanism 300. the suspension lugs 106 of the standard formwork 100, the demolding mechanism 600 is installed between two adjacent standard formwork 100, and the two adjacent standard formwork 100 are Under the action of the demolding mechanism 600, the die is demolded or supported. The large-diameter integral moving metal template is connected by a plurality of arc-shaped standard templates 100 to form a doubl...

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...
