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...

Problems solved by technology

After the construction of a single module is completed, there is no unified plan for the dimensional accuracy of the entire structure, which often results in deviations in the accuracy of the overall structure

Moreover, since the accuracy of a single module interacts with other modules, in the absence of a unified measurement benchmark, there may be deviations in the combination and installation of each module, and in severe cases, it may even affect the combined installation of each module
