A start-up construction method for a large-span cylindrical reticulated shell structure gable in a coal storage yard

Abstract

The invention relates to a construction method of a net rack, in particular to a starting construction method for a large-span gable wall of a cylindrical latticed shell structure for a coal storage yard. The gable wall is manufactured by small spliced unit grounds, and is overhung to expand splicing, so that the construction speed is high. The coal delivery work of the coal storage yard is not affected, so that a purpose of construction while working is achieved. The large-span cylindrical latticed shell structure is constructed in a special working condition environment of the coal storage yard by adopting a method of using the small spliced units, starting the gable wall, decreasing progressively layer by layer, constructing row by row upward and overhanging to expand splicing. By combining gable wall starting by way of splicing, the method divides construction sections reasonably. Started from two ends of the gable wall, the gable wall is mounted upward lattice by lattice, cylindrical shell net racks on two sides are mounted at the same time, the cylindrical shell net racks on the two sides in starting are decreased progressively row by row along the mounting height, supportingpoints are arranged in a spaced manner in a starting internal chord of the gable wall, and hawsers are pulled in different heights on two sides, so that the integral stability is ensured. The gable wall is manufactured by small spliced unit grounds, and is overhung to expand splicing, so that the construction speed is high.

Description

technical field [0001] The invention relates to a construction method of a network frame, in particular to a starting construction method of a large-span cylindrical reticulated shell structure gable in a coal storage yard. Background technique [0002] In order to meet the requirements of environmental protection, there are more and more projects for the closure of new coal storage yards (stockyards) and the renovation and closure of existing coal storage yards (stockyards). Cylindrical reticulated shells include cylindrical reticulated shells and three-core cylindrical reticulated shells. , is the most widely used coal storage structure. It has beautiful appearance, reasonable shape, high structural rigidity, and is widely used in line with the shape of coal pile and the force requirements of large-span structures. The gables at both ends can be closed or semi-closed. According to the coal storage in the coal yard, the height of the coal pile and the working radius of the ...

Problems solved by technology

However, for the specific environment of the coal storage yard, during the construction period, the coal stacking and stacking and reclaiming equipment on the site must be in normal operation to meet the production needs. The construction site and the coal stacking site are used alternately, the site is complex, there are many cross operations, and the lifting equipment is displaced It is difficult, and the application of the traditional method of directly building the cylindrical reticulated shell in the coal storage yard will affect the specific coal stacking operation. In view of this contradiction, it is urgent to improve the existing cylindrical reticulated shell structure method
