Problems solved by technology

This umbrella-type submarine suction anchor can be well used in the technical field of marine wind power foundations. However, this umbrella-type submarine suction anchor foundation is the same as the traditional suction foundation, and it may be damaged due to improper negative pressure control during construction and installation. The formation of soil plugs leads to the problem of low actual bearing capacity. In addition, it is also prone to inclination during the subsidence process, requiring frequent corrections

Abstract

The invention provides an installation device and installation method for an umbrella-type seabed suction anchor foundation, including an umbrella-type seabed suction anchor foundation. The upper part of the submersible pump is connected, and the reversing valve and valve are set in the injection pipe. The submersible pump is adjacent to a pressure-resistant container. The pressure-resistant container contains an inclinometer and a gyro compass. On the branches, a frame is set around the pressure-resistant container and the submersible pump, and the signal optical cable is connected to the upper end of the frame. The installation method includes wharf loading, navigation positioning, docking of penetration equipment, foundation launching, penetration of umbrella-type seabed suction anchor, and recovery of penetration equipment. Utilizing the installation equipment of the umbrella-type submarine suction anchor foundation makes the installation method of the submarine umbrella-type submarine suction anchor simple, and is convenient for dealing with problems such as soil plugs and inclinations that occur during the installation process of the umbrella-type submarine suction anchor foundation, and has a high reuse rate.

Description

technical field [0001] The invention belongs to the technical field of marine engineering, and relates to an installation device and an installation method for an umbrella-type seabed suction anchor foundation used in an offshore wind farm. Background technique [0002] With the rapid development of offshore wind farm construction in recent years, the foundation design and installation of offshore wind turbines has become an important topic in this field. At present, the main foundations used in offshore wind turbines are in the form of single pile foundation, gravity foundation, pile group foundation, suction foundation and so on. [0003] The single pile foundation is the simplest foundation structure, and its diameter is determined by the magnitude of the load, generally around 3-5m. The monopile foundation is suitable for waters where the water depth is less than 30m and the seabed is relatively hard. It does not require pretreatment of the seabed and is easy to manufac...
