Method for releasing deepwater net cage anchorage system

Abstract

The invention discloses a method for releasing a deepwater net cage anchorage system. The method includes the steps of firstly, inserting a vibrator in a split anchor inner cavity, and fixing a split anchor at the head of the vibrator; secondly, connecting a mooring rope with a pull rod; thirdly, starting a winch to allow the vibrator and the split anchor to enter water fast; fourthly, starting a high-pressure water pump to allow a high-pressure water outlet to spray high-pressure water, and starting the vibrator at the same time; fifthly, when the split anchor reach the set depth, using the winch to hoist the vibrator to allow the split anchor to be separated from the vibrator; sixthly, continuously hoisting the vibrator to construction rack special for water surface; seventhly, connecting the mooring rope with a floating carrier on the water surface. The method has the advantages that the method is simple to operate, fast in operation, safe and reliable and low in construction cost, various complex geological conditions can be overcome to allow the anchor to reach the set depth, the released anchor is large in holding power to weight ratio and high in wind and wave resistance, and the like.

Description

technical field [0001] The invention relates to a construction method for placing deep-water cage anchorage systems in rivers, rivers, lakes, oceans and port operations. Background technique [0002] In rivers, rivers, lakes, oceans and ports, fixed floating platforms, deep-water net cages, floating trestles, piers and other floating carriers all need a reliable anchorage system to ensure that they have very good anti-wind and wave performance. There are mainly four types of anchoring systems used on water platforms such as net cages: one is iron anchors. Light iron anchors have low grip and are prone to anchor slipping; heavy iron anchors are costly and difficult to transport and release. The second is the pile anchor. Due to the use of the pile machine, it can only be operated in shallow water, and the power of the pile machine is small, the wood pile anchor is shallow, the anchor grip is small, and the wind and wave resistance is weak. The third is the cement block ancho...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the anchorage system in the prior art is difficult to put into construction, the operation period is long, and the construction cost is high, and the anchorage system has low anchor holding force, easy drift, and wind and wave resistance after being put into place. Weaknesses such as the above defects, provide a simple operation, fast operation speed, safe and reliable, low construction cost, and can overcome various complex geological conditions to release the anchor body to the set depth, and the anchor weight ratio after the anchor body is put in place The construction method of the deep water net cage anchorage system with large and strong wind and wave resistance
