Test device and simulation method of deepwater anchor mooring body construction process simulation

Abstract

The invention relates to a test device and a simulation method of deepwater anchor mooring body construction process simulation. The device comprises a test box, a seabed simulation system is arrangedinside the test box, and a water pressure control system used for applying a water pressure to the test box to simulate a deep sea water pressure environment is arranged outside the test box, and thetop of the test box is provided with an extension part which extends upwards to form a lower penetration space; and the top of the extension part is provided with a slurry inlet, a slurry passing channel and an anchor body of a slurry outlet, an anchor body releasing system used for releasing an anchor body is further arranged at the top of the extension part, and a grouting system connected withthe anchor body is further arranged outside the test box. The test device and the simulation method of the deepwater anchoring body construction process simulation has the advantages that the simulation test device is compact in structure, the problem that a novel deepwater anchor mooring body laboratory simulation cannot be realized can be effectively solved; and meanwhile, the simulation methodis simple and convenient.

Description

technical field [0001] The invention relates to a simulation test device and a simulation method for the construction process of a deep-water mooring body. Background technique [0002] In the process of developing offshore resources, it is necessary to build a large number of offshore platforms. These platforms need to be held in place by mooring devices during their service. Traditional mooring bodies have the problems of complicated construction process or small mooring force. For this reason, the inventor proposed a new type of mooring body. The grouting pipe is brought deep into the seabed through the modified dynamic penetration anchor. anchoring force. [0003] In order to study the construction effect of the new mooring body under different conditions, it is necessary to simulate the construction process in the laboratory to detect the depth of the anchor body penetrating into the seabed and the diffusion range of the grout. However, currently there is no device ...
