Construction method of circular reinforced concrete chimney cylinder wall and hydraulic sliding mould device

The invention discloses a construction method of a circular reinforced concrete chimney cylinder wall, and a hydraulic sliding mould device, wherein a hydraulic sliding mould construction method is a rapid construction method of dynamically and continuously molding concrete; loads such as an operation platform and a template are completely supported on a support rod which is stabilized by low-age concrete and has small rigidity; the operation platform and the template are driven to climb along the cylinder wall by a hydraulic jack; and the hydraulic jack climbs on the support rod by an oil path system. The hydraulic sliding mould construction employing the sliding mould as an external cylinder wall and building a lining adopts an ''outside sliding and inside building'' construction process featured by synchronously constructing the external cylinder wall and the lining. The hydraulic sliding mould construction is featured by dynamic continuous construction, having fast construction speed in comparison with mould reverse, symmetrically distributing the hydraulic jack on the circumference of the chimney cylinder wall, forming the template by combining a fixed template with a moveable plate and a contracting and separating template, convenient to assemble and dismount as well as regulate the diameter and the circumference of the combined template structure, capable of gradually decreasing the diameter and the circumference of the combined template structure along with the diameter change of the chimney diameter. The hydraulic sliding mould construction is advantaged in few invested construction operators and convenient management.
