Gas-liquid two-phase flow jetting pile shoe

Abstract

The invention relates to a gas-liquid two-phase flow jetting pile shoe and belongs to the technical field of ocean platforms. The gas-liquid two-phase flow jetting pile shoe comprises a pile, a high-pressure water inlet pipe, a high-pressure air inlet pipe, a fixed block, a rotary block, a spiral pipe, a flow mixing pipe, a nozzle and a pile shoe, wherein the high-pressure water inlet pipe and the high-pressure air inlet pipe are symmetrically arranged in the fixed block; the rotary block is arranged below the fixed block; the rotary block and the fixed block are arranged on the upper side inthe flow mixing pipe; the spiral pipe is arranged in the rotary block; the rotary block is in clearance fit with the flow mixing pipe; the flow mixing pipe below the rotary block is a conical body; the fixed block, the rotary block and the flow mixing pipe are made of stainless steel materials; the high-pressure water inlet pipe, the high-pressure air inlet pipe, the fixed block, the rotary blockand the flow mixing pipe are arranged in the pile; two water and air outlet pipes are formed through divergence below the flow mixing pipe; and the two water and air outlet pipes pass through the pile shoe upwards to form the nozzle. The pile shoe jets a rotary gas-liquid two-phase body, and sludge on the upper part of the pile shoe can be easily and quickly removed through cavitation.

Description

technical field [0001] The invention relates to a jetting spud shoe, in particular to a gas-liquid two-phase flow jetting spud shoe, and belongs to the technical field of offshore platforms. Background technique [0002] During the development of marine resources, mobile offshore platforms are used more and more widely. Some offshore platforms equipped with spud cans are difficult to pull out due to the mud on the upper part of the spud cans when the offshore platforms need to be moved. , an existing method is to use high-pressure water flow to spray from the inside of the spud can, but sometimes the spray effect is not good, so there is an urgent need for a new method that can quickly and effectively remove the upper silt. Contents of the invention [0003] The object of the present invention is to provide a gas-liquid two-phase flow spouting spud can which can improve the spouting effect. [0004] The problem to be solved by the present invention is the deficiency that ...
