Novel steel pipe crossed core-inserting pile

Abstract

The invention discloses a novel steel pipe crossed core-inserting pile, which comprises a steel tube body. A crossed steel support is vertically inserted to the center of the steel tube body. A hollowsteel reinforcement cage is fixed at the outside of the crossed steel support in a welding mode. The void between the steel reinforcement cage and the inner wall of the steel tube body is filled withconcrete. The void between the steel reinforcement cage and the crossed steel support is also filled with concrete. The novel steel pipe crossed core-inserting pile is simple and reliable in overallstructure, ingenious in design and convenient to manufacture and construct, and has a long service life. The ability of anti-overturning and anti-sliding in the process of towing, sinking or using ofan ocean platform can be greatly improved. The large-scale promotion and use in the ocean platform engineering field is facilitated.

Description

technical field [0001] The invention relates to a bottom supporting device of an ocean platform, especially a new type of steel pipe cross with simple and reliable structure and ingenious design, which can greatly improve the ability of the ocean platform to resist overturning and anti-slip during towing, sinking or use. Mortise pile. Background technique [0002] An offshore platform is a structure that provides production and living facilities for activities such as drilling, oil extraction, consolidation, observation, navigation, and construction at sea. The structure of the offshore platform is complex, bulky and expensive, especially compared with land oil production equipment, the marine environment it is in is very complex and harsh, typhoons, waves, currents, sea ice and tides, and submarine earthquakes have a great impact on the safety of the platform. security poses a serious threat. At the same time, due to factors such as environmental corrosion, marine organis...

Problems solved by technology

The structure of the offshore platform is complex, bulky and expensive, especially compared with land oil production equipment, the marine environment it is in is very complex and harsh, typhoons, waves, currents, sea ice and tides, and submarine earthquakes have a great impact on the safety of the platform. poses a serious threat to the security of

At the same time, due to factors such as environmental corrosion, marine organism adhesion, foundation soil erosion and foundation dynamic softening, component material aging, defect damage expansion, and fatigue damage accumulation, etc., the platform structural components and overall resistance will gradually decay, affecting the service safety of the platform structure. and durability
