Underwater soil coagulator

Abstract

A best prevention and control method is unavailable for offshore wind power flourishing and upset and wind power pile foundation erosion prevention all the time, and under the guidance of colleges ofall parties, the inventor accidentally finds that a underwater soil coagulator is good in wind power pile foundation erosion prevention and control effect through multiple tests on site. The underwater soil coagulator comprises silty sand, cement and a soil cementing agent (developed and synthesized from various materials), an underwater soil coagulator mixture is input into the root of a fillingpile through a high-strength pressure pump, rapid initial setting is conducted within a short time, the strength reaches C15 or above after one week, soil around a pile foundation is solidified and bears scouring of two tides every day without being affected, and the anti-scouring problem of the offshore wind power pile foundation is effectively solved.

Description

technical field [0001] The invention relates to the technical field of anti-scouring of offshore wind power pile foundations, and more particularly relates to an underwater soil coagulant. Background technique [0002] After the foundation construction of offshore wind turbines, the pile foundation changes the original hydrodynamic conditions such as waves and currents in this area, breaking the established sediment transport balance, and causing the seabed around the pile foundation to scour. When the sea current encounters the obstruction of the pile foundation, it will flow around, and the flow velocity around the pile foundation will increase. The horseshoe-shaped vortex formed around the pile foundation and the denudation vortex behind the pile foundation are the main driving forces for the erosion of the pile foundation. According to the principle of scour, it can be known that scour pits around the foundation piles are formed by the joint action of wave current scour ...

AI Technical Summary

Problems solved by technology

[0004] At present, offshore wind power has taken some protective measures, such as throwing down the protective piles. Since the rocks are thrown into the pile foundation pit, the gaps between the stones still cannot prevent the tidal pumping and take away the sand below, causing the rocks to sink. After the edges and corners sank to the cable, the cable was evacuated by the tide, causing the cable to be damaged. After a year of scanning, it was found that the rocks had sunk and the foundation pit was still growing, and the anti-scour effect was not good.
