A marine deepwater pipe pile foundation with anti-seepage and force transmission connection

Abstract

This application relates to a marine deep-water pipe pile foundation with anti-seepage and force transmission connection, which belongs to the technical field of marine deep-water foundation, including: pipe pile foundation, the inner wall of the pipe pile foundation is provided with an inner steel pipe, and the bottom of the inner steel pipe is provided with a bottom inside section; force transmission key, the force transmission key includes vertical ribs and horizontal ring ribs, which are integrated with the bottom cover section. There are round holes on the ribs, and the horizontal ring ribs are arranged in the round holes of multiple vertical ribs; the anti-seepage ring, the anti-seepage ring is located under the force transmission key, and is fixedly connected to the inner wall of the inner steel pipe, and embedded with the bottom cover section. Solidify. The marine deep-water pipe pile foundation of this application can meet the force transmission requirements of the inner steel pipe and the bottom cover section, and can effectively prevent seawater from infiltrating into the cavity of the marine deep-water pipe pile foundation from the base, ensuring the vertical bearing capacity of the marine deep-water pipe pile foundation and durability.

Description

technical field [0001] The application relates to the technical field of marine deep-water foundations, in particular to a marine deep-water pipe pile foundation with anti-seepage and force transmission connections. Background technique [0002] The ultra-large-diameter pipe pile foundation has the advantages of light weight, high horizontal stiffness, high bearing capacity, and low construction risk. It is a very good choice for deep-water foundations in marine engineering with harsh construction conditions. [0003] The inside of the pipe pile foundation is a hollow structure. In order to take advantage of the hollow structure, the buoyancy of the hollow part can be effectively used by increasing the area of ​​the pile end and pumping water inside the pipe pile to reduce the stress of the base and increase the vertical bearing capacity of the foundation. A bottom cover section is set at the bottom of the foundation, and at the same time, the water in the cavity of the pipe...
