Offshore wind power high-piled cap foundation berthing system and construction method

Abstract

The invention discloses an offshore wind power high-piled cap foundation berthing system and a construction method. The system comprises a concrete cap and a berthing component; a plurality of cap embedded parts are embedded in the upper portion and the lower portion of the concrete cap; and the berthing component comprises a plurality of vertical berthing steel pipes and horizontal bollards fixedly connected with the berthing steel pipes. The berthing component and the concrete cap are connected through steel welding instead of bolt connection of impingement plates and are formed by welding impingement steel pipes with the diameter being 406 mm instead of the impingement plates, the overall stability is good, and the long-term requirements for adjusting, operation and maintenance work offan equipment can be met. A lower cantilever section is additionally provided with a hoop connected with an adjacent steel pipe pile and is connected with the impingement steel pipes, mutual connection and fixation of the whole system are achieved, the impingement steel pipes are prevented from swinging, and the lateral stress performance of the berthing system is enhanced. The two sides of the berthing system are each provided with the three bollards from top to bottom, and the line mooring and berthing requirements of ships under different water levels can be met.

Description

technical field [0001] The invention relates to the technical field of offshore berthing cap technology and equipment, in particular to a berthing system and construction method for offshore wind power high pile cap foundations. Background technique [0002] With the rapid development of wind power technology, there are fewer and fewer onshore wind farms that can be developed and utilized, while offshore wind power development is getting more and more attention. As the basic facility for offshore wind power development, the foundation of offshore wind turbines will inevitably encounter ship collision problems during the early construction and later operation and maintenance processes. Aiming at the problem of ship collision, certain protective measures can be taken to reduce the force on the basic support structure, thereby reducing the damage of the ship to the support structure. At present, the commonly used method is to set up berthing parts on the foundation support str...

Problems solved by technology

However, this system has many disadvantages. For example, the vertical load of the entire rubber fender berthing device is mainly borne by the shaft of the impact plate, the displacement space of the fender on the axis of the impact plate is relatively large, and the fender has a long gap below the foundation cap. The cantilever section (6.4m) has poor lateral force performance, and there are problems such as lateral tensile damage to the fender due to the mooring of the berthing ship

If there is a problem with the selection of steel bars for ladders, problems such as deformation and fracture of steel bars are prone to occur
