Abstract

The invention provides a manufacturing method for a sectional main chord tube of a truss type pile leg. The manufacturing method comprises the following steps of manufacturing a rack board: in the length direction, sequentially butt-jointing multiple rack board sections, welding and fixing adjacent two rack board sections to obtain the rack board with a set length, wherein the set length is the set length of pile leg sections; and performing half-chord tube welding: separately welding and fixing a half-chord tube on two side planes of the rack board, thereby forming a main chord tube. According to the manufacturing method for the sectional main chord tube of the truss type pile leg, the rack board is manufactured firstly, and the rack board as long as the pile leg sections is obtained; then, the main chord tube is welded to the rack board, so that the main chord tube is obtained. In the whole process, a window board does not need to use, so that manufacturing and mounting processes ofthe window board are reduced, the processing cost is reduced by 10% or above, and processing efficiency of the main chord tube is effectively improved.

Description

technical field [0001] The invention relates to the field of offshore engineering platform construction, in particular to a method for manufacturing a truss-type leg segmented main chord. Background technique [0002] The legs of the jack-up platform are the basis for the platform to lift. When the platform is operating, it bears the gravity and operating load from the platform itself, and also bears the wind load. Therefore, the strength of the pile legs is related to the safety of the platform and is one of the guarantee factors for the safety of the platform. Usually, the legs of the jack-up platform with an operating water depth of more than 200 feet adopt a truss structure, in which the main chord of the truss leg is the core component of the entire leg. The slats are welded. [0003] In actual construction, due to the weight limit, the length of the rack steel does not exceed 9 meters. In order to further reduce high-altitude operations, the length of the leg segmen...
