Prefabricate type nautical fixed platform and installing method

Abstract

The invention discloses a prefabricate type nautical fixed platform and an installing method. The prefabricate type nautical fixed platform and the installing method comprises following steps: 1) a temporary locating step: atoll bulging rocks can be used as a fulcrum, and a winding machine can be used for dragging a platform main body to a construction preinstallion position in a high tide level. A low tide level and a method of injecting water into a ballasting cabin can be used for contacting the bottom of the main body to a surface of a foundation, and locating piles are used for temporarily fixing the main body on the foundation. 2) A sinking leveling step: length that each locating pile extends out of the bottom of the main body can be controlled, and positions and levelness of the bottom of the main body can be adjusted. 3) A sinking fixing step: gravels which are in a gravel cabin can be discharged through a gravel channel to fill gaps between the surface of foundation and the bottom of the main body. Fixing of the prefabricate type nautical fixed platform can be completed. The prefabricate type nautical fixed platform and the installing method has the advantages of being stable in main body structure and low in manufacture cost. The function is easy to level. The prefabricate type nautical fixed platform and the installing method is high in planeness, accurate in fixing location and capable of being installed on the atolls or submerged rocks or sandy beaches. The prefabricate type nautical fixed platform is easy to construct and stable in fixing.

Description

technical field [0001] The invention relates to an offshore platform technology, in particular to a fixed offshore platform that can be quickly deployed on islands, reefs, and sandy beaches and an installation method thereof. Background technique [0002] With the continuous development and utilization of the ocean, operators and equipment need to stay in the open sea or near islands and reefs for a long time, so it is necessary to build a fixed operating platform or supply platform. There are two common construction methods. The first is to pre-install the floating island platform or caisson platform with steel structure, which is towed to the operation site by tugboat. The floating island platform is fixed at sea by anchor mooring or piling. The way of diving and sitting at the bottom sinks to the bottom of the water, and then builds the required superstructure for operation or supply on the platform exposed to the water. This kind of steel structure floating island platf...
