Method for constructing hyperbolic curve funnel wall of tamping coke coaling tower

Abstract

The invention relates to a method for constructing a hyperbolic curve funnel wall of a tamping coke coaling tower, which comprises the following steps: (1) manufacturing and pre-installing a template for forming the hyperbolic curve funnel wall; (2) calculating a reinforcing steel bar support frame of a template of an external wall of the hyperbolic curve funnel wall, wherein the distance X between the external wall of the hyperbolic curve funnel wall and the coal tower vertical wall is equal to (d / 2)*e<kcy / 2> when the highness is increased by 500mm each time; (3) manufacturing the reinforcing steel bar support frame, wherein the reinforcing steel bar support frame is made of phi 25 twisted steel, and the gradient of the reinforcing steel bar support frame is the same as the gradient of the external wall of the hyperbolic curve funnel wall when the highness is increased by 500mm each time; (4) installing and fixing a template of an internal wall and the template of the external wall; (5) pouring and casting concrete; and (6) removing the templates and maintaining. The method provided by the invention is simple and easy, the curvature of the external wall of the hyperbolic curve funnel wall can be effectively ensured, the construction speed is improved, the construction quality is guaranteed, and the invention provides the safe and reliable method for constructing the hyperbolic curve funnel wall of the tamping coke coaling tower.

Description

technical field [0001] The invention belongs to the field of coal towers, in particular to a construction method for tamping a hyperbolic funnel wall of a coking coal tower. Background technique [0002] With the rapid development of the market economy and all walks of life, it is imperative to eliminate backward production capacity. The coking plant gradually eliminates small carbonization chambers and replaces them with large carbonization chambers. With the increase of the furnace type, the coal tower is also increasing, and the construction difficulty is also increasing. The tamping coking coal tower is composed of a long-span beam, a funnel mouth at the bottom of the warehouse, vertical walls around, a hyperbolic funnel wall, and a coal bunker roof. Among them, the hyperbolic funnel wall is the difficulty in the construction of the coal tower. If the curvature of the hyperbolic funnel wall of the coal tower cannot be guaranteed, it will not only affect the installation ...

Problems solved by technology

Among them, the hyperbolic funnel wall is the difficulty in the construction of the coal tower. If the curvature of the hyperbolic funnel wall of the coal tower cannot be guaranteed, it will not only affect the installation of the next equipment, but also seriously affect the use effect after commissioning. The hyperbolic funnel in the prior art The inner and outer walls of the wall are supported by steel formwork, scaffolding tubes or wooden formwork, square wood and scaffolding tubes. Because the scaffolding tubes are straight tubes, it is difficult to ensure the curvature of the hyperbolic curve of the outer wall of the hyperbolic funnel wall, and it is easy to produce when pouring concrete. Die expansion phenomenon, high labor intensity and slow construction progress
