Vertical shaft construction stepping-type template based on hydraulic drive and working method thereof

Abstract

The invention relates to a vertical shaft construction stepping-type template based on hydraulic drive and a working method thereof. The vertical shaft construction stepping-type template comprises two parts, one is an upper expandable shoe part, expanding a concrete well wall or separating from the concrete well wall of upper expandable shoes is realized through extending or retracting a piston rod of a expandable shoe oil cylinder; and the other is a template body part, template bodies can move downward or upward through extending or retracting the piston rod of a step oil cylinder, at the same time, the expansion of a template body expanding oil cylinder can press the template bodies and release the template bodies when well wall concrete is poured, and the combination of alternate actions of the expandable shoe oil cylinder, the step oil cylinder and the expanding oil cylinder can realize the automatic circulation of the vertical shaft construction process. According to the vertical shaft construction stepping-type template based on hydraulic drive and the working method thereof, the harsh operation environment of a deep well can be well adapted, and the vertical shaft construction efficiency and safety reliability are improved.

Description

Technical field [0001] The invention relates to the technical field of mine construction, in particular to a stepping template for vertical shaft construction based on hydraulic drive and a working method thereof. Background technique [0002] At present, in the process of mine shaft excavation, most of the formwork supporting reinforced concrete is moved manually, and the frame is moved manually every time the concrete is poured for a certain distance. This operation method takes a long time and greatly restricts the speed of shaft excavation. At the same time, the labor intensity of workers is high, and because the working environment in deep wells is very bad, the lives of the workers are threatened. There are still some shortcomings in the current related solutions: the hydraulic stepping shaft formwork support device (CN102305076A) has low system integration, inconvenient installation and debugging, and the overall efficiency is not high, and it cannot form a working cycle; ...

Problems solved by technology

[0002] At present, during the mine shaft excavation process, the formwork supporting the reinforced concrete is mostly moved manually, and the frame is manually moved every time a certain distance of concrete pouring is completed. This operation method takes a long time and greatly restricts the speed of shaft excavation.

At the same time, the labor intensity of the workers is high, and because the working environment in the deep well is very bad, the life safety of the staff is threatened

There are still some deficiencies in the current related schemes: the hydraulic stepping shaft formwork support device (CN102305076A) has low system integration, inconvenient installation and debugging, the overall efficiency is not high, and the work cycle cannot be formed; the stepping hydraulically operated integral metal formwork (CN101660421A ) adopts the stepping ring structure to make the operation complicated and low in efficiency; the shaft has no suspension and the step-down integral metal formwork (CN107083976A) can only realize the movement through the longitudinal support and guidance, and cannot avoid the circumferential movement of the upper and lower formwork during the movement
