Guide pipe frame closing process, supporting frame and supporting assembly

Abstract

The embodiment of the invention discloses a guide pipe frame closing process, a supporting frame and a supporting assembly. The process comprises the following steps of constructing the supporting assembly; positioning and placing the lower section of the guide pipe frame; and integrally closing the guide pipe frame. The supporting frame comprises at least one placing plate placed on an operatingplatform, a sliding rail arranged on each placing plate, and a plurality of carrying workpieces slidably arranged on the sliding rail, and the plurality of carrying workpieces are provided with box beam tools used for placing main supporting tubes. The supporting assembly comprises the supporting frame, and a power supply unit for pulling the carrying workpieces to slip along the slip rails. According to the process, the supporting frame and the supporting assembly, a common wharf can also be operated in the field, the problem that the cost is increased due to the fact that an independent machining area is divided is avoided, meanwhile, the carrying difficulty in the adjusting process is further reduced, and the carrying efficiency is improved.

Description

technical field [0001] The embodiment of the present invention relates to the field of jacket installation and closing, and in particular to a jacket closing process, a support frame and a support assembly. Background technique [0002] The jacket is mainly a basic frame structure used in the fields of offshore oil platforms, offshore lighthouse construction and offshore wind power. Due to its large volume, the overall weight is relatively heavy. During the construction process, its bottom is generally in direct contact with the wharf ground through the main support pipe. However, under the premise of its heavy weight, the bearing capacity of the wharf ground It is often difficult to meet the demand. Therefore, it is often necessary to process it in a fixed processing area during the closing operation and then transport it to the dock. It further adjusts the position, and the hoisting after the overall closing also greatly increases the difficulty of the entire hoisting pro...

Problems solved by technology

Due to its large volume, the overall weight is relatively heavy. During the construction process, its bottom is generally in direct contact with the wharf ground through the main support pipe. However, under the premise of its heavy weight, the bearing capacity of the wharf ground It is often difficult to meet the demand. Therefore, it is often necessary to process it in a fixed processing area during the closing operation and then transport it to the dock. It further adjusts the position, and the hoisting after the overall closing also greatly increases the difficulty of the entire hoisting process, which will cause the problem of high handling costs in the entire process

[0003] In the prior art, for example, CN105019419A discloses a jacket, a jacket foundation platform and a jacket construction method, but it itself is only a simple construction of the jacket structure, and it is difficult for ordinary wharves to meet its construction requirements during the construction process. The demand for conditions and the high cost of handling have not given any relevant explanations

Obviously, in the prior art, construction improvements are often made from the entire structure of the jacket, and even in some cases, by setting transition sections, etc., and these methods are more complex to some extent It makes the whole construction process more complicated
