Problems solved by technology

[0002] At present, the floating inspection door is usually constructed by the method of overall assembly and overall anticorrosion. With the country's vigorous construction of the Yangtze River Basin, there are more and more large-scale hydropower stations, and the floating inspection door is getting bigger and bigger. The large floating inspection door The gate length is greater than 35m; the maximum gate width is greater than 5m. The lifting equipment of the existing Yangtze River Basin manufacturing plant cannot meet the requirements, and the existing overall anti-corrosion construction method greatly increases the difficulty of anti-corrosion construction

Abstract

The invention discloses a construction method of a large floating maintenance door. The method comprises the following steps: (1) a first beam body, a second beam body, a third beam body, a fourth beam body, a fifth beam body and a sixth beam body are assembled; (2) a truss is assembled; (3) edge columns are assembled; (4) a maintenance door lower half body is manufactured; (5) a fender is assembled on the truss to manufacture a maintenance door middle body; (6) a maintenance door upper half body is manufactured; (7) a whole maintenance door is manufactured; (8) the edge columns are mounted onthe whole maintenance door; (9) the corrosion-resistance treatment is performed on the whole maintenance door; and (10) the construction of the large floating maintenance door is finished through assembly and welding. The construction method of the large floating maintenance door can solve the problems of assembly and corrosion resistance of the large floating maintenance door, is simple, feasible and convenient for corrosion-resistance construction, and greatly reduces the tonnage requirements on lifting equipment.

Description

technical field [0001] The invention relates to the field of construction of hydraulic gates, in particular to a construction method of a large floating inspection gate. Background technique [0002] At present, the floating inspection door is usually constructed by the method of overall assembly and overall anticorrosion. With the country's vigorous construction of the Yangtze River Basin, there are more and more large-scale hydropower stations, and the floating inspection door is getting bigger and bigger. The large floating inspection door The gate length is greater than 35m; the maximum gate width is greater than 5m. The lifting equipment of the existing Yangtze River Basin manufacturing plant cannot meet the requirements, and the existing overall anti-corrosion construction method greatly increases the difficulty of anti-corrosion construction. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a construction m...
