Problems solved by technology

Although this structure can realize the basic transportation function, but in the sea, due to the strong wind and waves, the extended support beam is prone to sloshing, which will cause damage to the transportation pipeline at the swaying position

Embodiment Construction

[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0039] A method for building a temporary trestle on an offshore platform, comprising the steps of:

[0040] Step 1: On-site inspection and confirmation: personnel go to the offshore platform 1 to measure and take pictures, survey the site environment, and predict weather information in advance to ensure a good construction environment during construction, including wind, tide and other meteorological data, and record and analyze them , to ensure that the construction can be carried out normally, safely and efficiently, and select the adjacent passage positions of the two offshore platforms 1 for detailed survey and survey, record and analyze the layout of peripheral equipment, and provide data analysis and support for the later construction of temporary trestles.

[0041] Step 2: Pre-preparation: Prepare construction tools and workpieces, including scaffoldin...

Abstract

The invention discloses an erecting method of a temporary trestle for ocean platforms and belongs to the technical field of channel erecting. The erecting method has the advantage that a temporary channel with the good wobbling bearing effect can be conveniently erected between the two ocean platforms. According to the technical scheme, the erecting method is characterized in that the following steps that on-site inspection and confirming, early-stage preparation, erecting of supporting scaffolds, erecting of inclined supports, arrangement of a door-type steel structural frames, connecting ofsteel wire ropes, paving of step plates, erecting of the intermediate channel and erecting of guardrails are conducted sequentially.

Description

technical field [0001] The invention relates to the technical field of channel building, in particular to a method for building a temporary trestle bridge on an ocean platform. Background technique [0002] Ocean platform is the most important equipment for developing ocean energy. [0003] In the process of offshore energy development, multiple offshore platforms may be required to cooperate with each other, and the offshore platforms between each other basically need to build trestles to connect, for personnel to move around, oil, gas, water, electricity and other material transportation. [0004] The Chinese patent with the notification number 101565929 discloses a trestle connection method and a special device between offshore platforms. It forms a space truss structure by adding support beams and triangular or trapezoidal bridge decks. Although this structure can realize the basic transportation function, in the sea, due to the strong wind and waves, the extended suppo...
