Combined-type simple ocean platform and construction method thereof

Abstract

The invention discloses a combined-type simple ocean platform and a construction method thereof. The combined-type simple ocean platform comprises square steel frameworks, steel plates, steel piles and an upper operation platform. The upper operation platform is formed by welding of four hollow vertical columns and a platform plate. Transverse and slanting staypoles are welded among the four vertical columns to form a space net rack system. Sleeves are symmetrically welded to the side faces of the bottoms of the four vertical columns through steel pipes. When construction is conducted, the four steel piles are driven, the four steel piles are sleeved with the first square steel framework based on the sleeves; then the steel piles are sleeved the steel plates based on strip-shaped holes; the four steel piles are sleeved with the second square steel framework; the upper operation platform is hoisted on the basis that the four steel piles are sleeved with the four sleeves and fixed through bolts; and a foundation is pressed to the stable state through the seawater weight, and accordingly the simple ocean platform is constituted. The ocean platform is simple in structure, small in member weight and large in foundation base area. The foundation is subjected to preloading consolidation through the seawater weight. The ocean platform is suitable for the construction environment with sludge and an intertidal zone and has economy and practicability properties.

Description

[0001] Technical field: [0002] The invention relates to an offshore platform structure, in particular to a combined simple offshore platform and a construction method thereof. [0003] Background technique: [0004] my country's marine tidal flats and intertidal zone are rich in land resources, which are characterized by large area, concentrated distribution, good location conditions, and great potential for comprehensive development of agriculture, animal husbandry and fishery. The intertidal zone is an important base for aquaculture and the development of agricultural production, and a valuable asset for developing the ocean and marine industry. [0005] Generally, simple offshore platforms need to be built in tidal flats and intertidal zones for marine operations. The soil layer in tidal flats and intertidal zones is soft and the bearing capacity is low, and the intertidal zone is affected by tidal fluctuations, the duration of high water levels in a day is short, and the...

Problems solved by technology

However, if the length and weight of the pile foundation are large, large-scale lifting and piling equipment are required, but the water level in the intertidal zone cannot accommodate large construction ships; if a barrel foundation is used, due to the limited high water level in the intertidal zone, the It is difficult for the barrel foundation to penetrate the seabed to the design depth under the action of pressure difference
