Underwater automatic construction system for negative-pressure barrel type structure

Abstract

The invention discloses an underwater automatic construction system for a negative-pressure barrel type structure. The underwater automatic construction system for the negative-pressure barrel type structure comprises a mounting frame, a hydraulic pump unit, a third pipeline and an automatic disassembling mechanism, wherein the mounting frame is detachably connected with a barrel type structure; the hydraulic pump unit is arranged on the mounting frame and is connected with a hydraulic and control unit through a cable; a first interface and a second interface are formed in the hydraulic pump unit; the first interface communicates with a first pipeline; the second interface communicates with a second pipeline; the third pipeline is fixedly arranged on the mounting frame; the third pipelinecommunicates with the first pipeline and the second pipeline separately; the automatic disassembling mechanism is arranged on the third pipeline; fixation and separation of the third pipeline and a fourth pipeline can be realized through the automatic disassembling mechanism; and the fourth pipeline is arranged on the barrel type structure. Fully-automatic sinking or floating of the barrel type structure can be realized, so that the underwater automatic construction system for the negative-pressure barrel type structure can adapt to underwater construction environments such as China's offshorewaters on which a large amount of soft clay is distributed; and in the process of assisting in completing pile sinking, the underwater construction time can be greatly reduced.

Description

technical field [0001] The application belongs to the technical field of underwater automatic construction, and in particular relates to an underwater automatic construction system for a negative pressure barrel structure. Background technique [0002] With the increasing number of offshore construction, a large amount of soft clay is distributed in my country's offshore waters. These soils have the characteristics of high water content, low permeability, high compressibility, and low strength, and the distribution layer is very thick. If pile foundations are used, the The load level is relatively high, and the size of the pile foundation often needs to be designed very large to penetrate the soft soil layer and enter the bearing layer with a deep buried depth. The investment is huge and the construction time is long. The traditional pile sinking process has gradually revealed its singleness and limitations. This application proposes an underwater automatic construction syste...
