Embodiment Construction

[0022] An embodiment of the present invention is as follows: figure 1 with figure 2 The shown cylindrical foundation seawall structure spanning and protecting the submarine pipeline is composed of a cylindrical foundation inserted into the seabed soil and an upright cylindrical superstructure sitting on it and connected to it as a whole. The four cylindrical foundations Bottomless and top-covered cylinders 1 are arranged in a rectangle, and through-holes 5 are provided on the top cover 2 of each cylinder. The installed cylinders are located on both sides of the submarine pipeline 6, and the submarine pipeline is the same The two cylinders on the side are connected through the connecting plate 7 between the side walls of the cylinder, and also connected through the top cover plate 2, and the cylinders on both sides of the submarine pipeline are connected through the arched connection structure at the top of the cylinder. 3 are connected, and above the cylinder top cover plate...

Abstract

This invention discloses a lie across submarine line protective barrel shape foundation coastal dike structure and installation method. It consists of seabed inserted barrel shape foundation and wave or soil stop wall on it, wherein the barrel shape foundation consisting of four integrated barrel units, each side of submarine line has two barrel unit connected by connection board and top cover board, four barrel units are connected by arc shape board. Said structure is fabricated on land, then conveyed to site for positioning by air floating, lying across submarine line, pumping out air and water in barrel units, inserting it to sea bed, putting upper structure on foundation and making joint. Said invention is easy installation, small settlement deformation, fine protection to submarine line, strong wave and soil stop effect and low cost.

Description

technical field [0001] The invention relates to a cylindrical foundation seawall structure spanning and protecting a submarine pipeline. It belongs to the building structure in the field of port, coastal engineering and petroleum engineering. Background technique [0002] With the extensive exploitation of my country's offshore oil and natural gas, a large number of offshore submarine pipelines have been laid, and some pipelines cross port breakwaters or dikes for land reclamation. Traditional breakwaters and embankment dikes have a heavy weight. On soft ground, when a large ballast is applied locally to the submarine pipeline, the submarine pipeline will be bent and the pipe wall will be broken due to excessive tensile stress. Therefore, special treatment needs to be done to structures such as breakwaters and dikes across submarine pipelines or submarine pipelines, such as building breakwaters and dikes after strengthening soft soil foundations, or...
