Embodiment Construction

[0053] See attached picture:

[0054] A combined simple offshore platform, including a square steel frame 1, steel plates 3, steel piles 9 and an upper operating platform, the upper operating platform is welded by four hollow columns 5 and a platform plate 6, and the four columns 5 are welded with Horizontal and oblique struts form a space grid system. The bottom sides of the four columns 5 pass through the symmetrical welded sleeves 7 of steel pipes. During construction, four steel piles 9 are first laid, and the first square steel The frame 1 is set on the four steel piles 9, and then the steel plate 3 is put on the four steel piles 9 based on the strip hole 4 and pressed on the first square steel frame 1, and then the second square steel is put on the second square steel frame based on the sleeve 2 The frame 1 is set on four steel piles 9 and pressed on the steel plate 3, and then the upper work platform is lifted based on the four casings 7 to cover the four steel piles 9,...

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...
