Embodiment Construction
[0017] refer to Figure 1-Figure 6 , an application of a hydraulic settlement system in a platform deck reconstruction process, including cutting support columns 3 and cutting anti-skid columns 4, and installing hydraulic jacks. Cutting support columns 3 and anti-skid columns 4 is a total of 36 columns in 4 horizontal rows and 9 vertical rows that support the overall weight of deck 1 on the platform, and 15 support columns 3 and 6 anti-skid columns 4 of hydraulic jacks 7 need to be installed , cut off 0.9-1.0 meters from the cushion box 2, and cut the support column 3 and anti-skid column 4 without hydraulic jack 7 by 0.45-0.55 meters, so that the upper deck 1 is lowered to the upper deck 1 side and the baseline is 4.5m Re-weld and fix at the height of the upper deck; to install the hydraulic jack 7, all the piping systems on the upper part of the support column 3 and the anti-skid column 4 of the upper deck 1 are cut off first, and then using the triangular stability characte...

The invention discloses application of a hydraulic settlement system in the deck floor refitting process. The application includes the steps of cutting supporting stand columns, cutting antiskid stand columns and installing hydraulic jacks. In the steps of cutting the supporting stand columns and cutting the antiskid stand columns, parts 0.9 m to 1.0 m long are cut away from the fifteen supporting stand columns and the six antiskid stand columns where the hydraulic jacks need to be installed in the upward direction from a settlement box, and parts 0.45 m to 0.55 m long are cut away from the supporting columns and the antiskid stand columns where the hydraulic jacks are not installed, and a whole upper deck falls to the 4.5 m height position of the edge distance base line of the upper deck to be welded and fixed again; in the step of installing the hydraulic cylinders, all pipe systems of the upper portions of the supporting stand columns and the antiskid stand columns on the upper deck are cut off, then the hydraulic jacks are installed according to the triangle stability characteristic and through the crisscross and interval matrix distribution method, and the hydraulic jacks are controlled through a control cabinet. The hydraulic settlement system has the advantages of being reasonable in design, convenient, reliable and safe to operate, low in cost and good in economical efficiency, being little influenced by sea conditions and weather, and being beneficial to large-span deck falling construction and the like, and is widely applied in an offshore petroleum production project.
Description
Technical field: [0001] The invention relates to a platform deck reconstruction process in oil offshore oil exploitation, in particular to an application of a hydraulic subsidence system in the platform deck reconstruction process. Background technique: [0002] The existing offshore oil exploitation platform component lowering process is generally a floating crane hoisting and coordinating construction. This construction technology has played a role in the landing of offshore platform components, but it also has the following shortcomings or deficiencies: ① high cost and low efficiency; ② poor safety and high risk; ③ greatly affected by sea conditions and weather; ④ large span The object hoisting construction is difficult. Invention content: [0003] The purpose of the present invention is to provide an application of a hydraulic settlement system in the platform deck renovation process, using cutting columns, and according to the triangular stability characteristics, hy...
