Underwater fixing structure and fixing method for net bodies

Abstract

The embodiment of the invention discloses an underwater fixing structure and fixing method for net bodies. The underwater fixing structure comprises the net bodies, pile bodies and hooks, wherein thepile bodies are fixed underwater, and the plurality of hooks are arranged on the pile bodies; the hooks comprise inner-layer hook bodies and outer-layer hook bodies, the inner-layer hook bodies are fixed to one sides of the pile bodies, and the outer-layer hook bodies are fixed to the outer sides of the inner-layer hook bodies; and each pile body is at least provided with two hooks which are distributed in parallel, one side of each net body is arranged on the inner-layer hook bodies of the two hooks of one pile body, the other side of each net body is arranged on the outer-layer hook bodies of the two hooks of the other adjacent pile body, and the two inner-layer hook bodies and the two outer-layer hook bodies of one pile body are all provided with the net bodies. According to the underwater fixing structure and fixing method for the net bodies, the fixed pile bodies are fully covered with the net bodies, and the adjacent net bodies mutually cover gaps generated by connecting the netbodies with the pile bodies, so that the problem that invaded objects invade through the gaps at the connecting positions between the net bodies and the pile bodies is solved; and the double-layer blocking net structure is arranged at the connecting positions of the pile bodies, so that the protection performance at the pile bodies is improved.

Description

technical field [0001] The invention relates to the technical field of underwater blocking, which is used for separating and isolating underwater areas, blocking and surrounding underwater objects, and in particular relates to an underwater fixing structure and fixing method of a net body. Background technique [0002] my country has a large number of important sea and port facilities, such as offshore oil drilling platforms, artificial islands, ports, docks, etc. Their protection involves two aspects: water surface and underwater. Among them, underwater protection mainly adopts the form of net body to separate the protected target from the external waters. In this way, the normal flow of seawater is not affected, and objects in the external waters can also be prevented from invading important facilities. [0003] At present, the way of laying out water or underwater nets is usually to use floating balls or buoys to connect the upper part of the net to make it float on the ...

AI Technical Summary

Problems solved by technology

[0006] In view of this, the present invention provides an underwater fixing structure and fixing method of the net body, which can solve the problem that the existing underwater blocking net and the underwater pile body are easily connected with gaps, reduce the leakage rate of the blocking net, and improve the overall Security performance of blocking net
