Embodiment Construction

[0028] Below in conjunction with accompanying drawing and embodiment the patent of the present invention will be further described.

[0029] A kind of suspension support method of underwater pipeline, it comprises the following steps: firstly arrange the empty bag body that is the smaller shrinkage state of volume with a middle space layer, fill reinforcing material in the middle space layer, as various long and short fibers ( Such as glass fiber, quartz fiber or Kevlar fiber, carbon fiber), filler, braid or sandwich material, and mix the reinforcement material with the resin;

[0030] Place the bag body at the position where it needs to be supported under the suspension span of the underwater pipeline, and fill the middle space layer with curing material such as adhesive;

[0031] Then fill the bag with seawater to expand, and the solidified material will form a stable underwater pipeline support shape and structure.

[0032] In the above-mentioned embodiment, the process of...

Abstract

The invention discloses a suspended span supporting method for an underwater pipeline. The suspended span supporting method for the underwater pipeline is characterized in that the stable underwater pipeline supporting shape and structure are formed by firstly arranging an empty bag body which is provided with a middle air interlayer and is in a relatively small-sized shrunk state, placing the bag body on a position required to be supported below the suspended span of the underwater pipeline, filling the middle air interlayer with a solidifying material, then, filling the bag body with a liquid or gas to expand the bag body, and then, solidifying the solidifying material. The invention also discloses a suspended span supporting device for an underwater pipeline by using the method. The suspended span supporting method and device have the advantages of low cost, convenience and simplicity in construction and short construction period.

Description

technical field [0001] The invention relates to the technical field of underwater pipeline fixed support at the bottom, in particular to the technical field of support for suspension spans of underwater pipelines, such as the suspension support technology for submarine pipelines. Background technique [0002] The needs of communication and oil transportation often require the laying of communication and oil transportation pipelines on the bottom of the water, especially on the bottom of the sea. Due to various factors such as the unevenness of the bottom surface, it is also necessary to set up supporting devices at the spans of the pipelines. Cause greater economic loss and social impact, the suspension support of underwater pipelines in the prior art, such as the suspension support technology of submarine pipelines, generally adopts the following methods: 1. Pile sandbags under the suspension span of the pipeline. Although this method is relatively simple, but Cannot form a...
