Non-slideway multi-module construction measuring method

Abstract

The invention discloses a non-slideway multi-module construction measuring method which comprises the steps of: 1, establishing construction site reference coordinates of an integral structure construction module; 2, determining reference coordinates of all submodules; 3, determining relative coordinates in the construction site reference coordinates according to positions of all submodules in reference coordinates of the submodules to obtain coordinate position information of parts in the submodules in the construction site reference coordinates; and 4, determining error requirements on the parts in accordance with the integral structure design size and error requirement according to the information of the part coordinate positions of the submodules. By adopting the method, construction allowance errors of the modules are obtained in the reference coordinates of the submodules, and integral assembly precision requirements are achieved after the submodules are integrally assembled.

Description

Technical field

[0001] The invention relates to a measurement method, in particular to a non-slide multi-module construction measurement method. Background technique

[0002] In offshore oil development projects, various platforms such as oil production platforms, living platforms, and central processing platforms need to be built offshore. The platform generally mainly includes: marine engineering blocks, underwater supporting structures-jackets, single points and other marine structures. Ocean engineering blocks, jackets, single points, etc. are commonly referred to as ocean structures. Marine structures are generally bulky and heavy, and modular design and construction methods are usually adopted in the construction process. Under this premise, the construction of structures needs to be divided, layered, and constructed at the same time to achieve the purpose of shortening the construction period and improving efficiency. Due to the continuous expansion of the weight and si...

[0016] In the process of decomposing an overall structure into multiple modules, the following steps are used:

[0017] (1) Establish the reference coordinates of the construction site for the construction module of the overall structure; (2) Determine the reference coordinates of each sub-module; (3) Determine the location of each sub-module in the reference coordinates of each sub-module The relative coordinates in the site reference coordinates are used to obtain the coordinate position information of the components in each sub-module in the construction site reference coordinates; (4) According to the overall structure design size and error requirements, according to the information of the coordinate position of the components in each sub-module, determine The error requirements of each component.

[0018] After testing: in the reference coordinates of each sub-module, the allowable error of the module is obtained, and after the overall installation, the overall assembly accura...
