Problems solved by technology

Its disadvantages are: when constructing a chimney with a high height, the center cage shakes a lot along the flexible slideway during the lifting process, which is unsafe for construction personnel to go up and down and the vertical transportation of some construction materials, and the lifting speed of the center cage slow

Embodiment Construction

[0023] As shown in the figure, the fixed derrick steel plate embedment 32 is pre-buried on the chimney foundation of conventional inverted mold construction, and the fixed derrick 29 is erected. The fixed derrick 29 is made of angle steel sections, connected by high-strength bolts, and the lower end of the fixed derrick is welded and fixed on On the steel plate embedded part 32, the upper end of the fixed derrick extends into the rising derrick 8, and is higher than a certain height of the construction operation platform; the chimney wall 27 of a certain height is constructed by conventional inverted molding, and the support rod 10 is pre-buried in the derrick by 25%. In the chimney tube wall 27 that has been constructed, the support rods 10 are generally made of Φ48mm×3.5mm steel pipes, which are welded butt joints. The number of support rods 10 is determined in advance according to the design of the sliding form construction device; The number of supporting rods is matched; t...

Abstract

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.

Description

technical field [0001] The invention relates to a construction method for a circular reinforced concrete chimney wall and a hydraulic sliding form device. Background technique [0002] The sliding form construction technology of the circular reinforced concrete chimney wall has been used in my country since the 1970s. Up to now, the sliding form technology includes sliding frame inverting, external sliding and internal lifting, external sliding and internal laying and self-elevating platform turning. mold and derrickless hydraulic sliding form, etc. Vertical transportation adopts electric hoist to lift the hanging cage in the center of the chimney through the hoisting derrick or directly adopts the construction hoist. [0003] The vertical transportation of the hydraulic sliding form without a derrick adopts the electric winch to lift the hanging cage in the center of the chimney through the rising derrick. Generally, the height of the rising derrick is 7.5m to 10.5m. Its d...
