Novel seabed low skirt type suction pile

Abstract

Disclosed is a novel seabed low skirt type suction pile. A pile body comprises a main barrel, a loading rod, a pile top, a skirt top and a skirt edge. The pile top is arranged in the main barrel. The loading rod is installed at the pile top. The skirt edge is connected with the skirt top perpendicularly, and the skirt top is connected and attached to the main barrel. The loading rod is provided with a guide rod threaded hole and a loading hawser hole. A guide rod is inserted into the guide rod threaded hole. The pile top is provided with a pile top water pumping hole and a negative pressure monitoring hole. The skirt top is provided with a water drain and water pumping multipurpose hole. Through the novel seabed low skirt type suction pile, the vertical bearing capacity, horizontal bearing capacity, flexural rigidity and shearing resistant rigidity of the pile body can be improved, the service life of the pile body can be prolonged, and flexural deflection is reduced.

Description

technical field [0001] The invention belongs to the technical field of marine engineering design and construction, in particular to a novel low-skirt suction pile on the seabed, which is suitable for foundations in marine soft clay foundations. Background technique [0002] With the development of society, people's demand for green new energy and renewable energy is becoming more and more obvious. The development of marine resources is getting more and more attention due to its unique advantages. Therefore, a solid foundation on the seabed is a necessary condition for the development of marine resources. . [0003] The existing suction piles have made great contributions to the development of marine resources, but there are still the following deficiencies: [0004] (1) It is difficult to control the verticality and pile top elevation of traditional suction piles during penetration; [0005] (2) The erosion of ocean currents around the pile body will cause the bearing capa...

AI Technical Summary

Problems solved by technology

[0004] (1) It is difficult to control the verticality and pile top elevation of traditional suction piles during penetration;

[0005] (2) The erosion of ocean currents around the pile body will cause the bearing capacity of the pile body to decrease;

[0006] (3) The horizontal and vertical bearing capacity is relatively weak;

This makes the ordinary skirt-type suction pile with the same height as the skirt top, and the effect of the skirt cannot be fully and effectively exerted due to the cavity under the skirt top.
