Problems solved by technology

[0005] Single-column rock-socketed construction is difficult, long-term, high-cost, and requires high requirements for rock-socketed equipment. At the same time, there are problems such as large equipment, less equipment, and high cost.
Therefore, a new type of fan foundation structure is currently designed: a single column-composite cylinder is combined to form a composite foundation, but there are still technical difficulties in the connection between the single column and the composite cylinder

Abstract

The invention relates to a connecting tooling used for a single column and composite cylinder combined foundation. A single column is inserted into a composite cylinder. The top end of the composite cylinder is provided with a fixed top cover plate. The connecting tooling comprises a connecting main plate and a plurality of stiffening webs fixedly connected to the lower plate surface of the connecting main plate. A connecting through hole adapting to the single column is arranged on the plate surface of the connecting main plate. The multiple stiffening webs are arranged around the connectingthrough hole, and the upper lateral sides of the stiffening webs are fixedly connected to the lower plate surface of the connecting main plate. The connecting main plate is connected to the single column in a sleeving mode, and the inner wall of the connecting through hole is welded to the single column. The inner lateral sides, facing the connecting through hole, of the stiffening webs are attached and welded to the columnar surface of the single column, and the lower lateral sides of the stiffening webs are attached and welded to the top cover plate. The connecting tooling related by the invention is simple in structure and convenient to mount and operate, the single column and the composite cylinder are stably connected and form an integrated structure, and big bending moment transmitted from the single column is transmitted to the whole composite cylindrical surface.

Description

technical field [0001] The invention relates to the field of offshore foundation construction, in particular to a connection tool for a combined foundation of a single column and a composite cylinder. Background technique [0002] As the renewable energy with the most exploitable value, wind energy has attracted worldwide attention. Offshore wind farms have good prospects for development because of their advantages such as high wind speed, long effective power generation time, no land occupation, and close distance to load centers. my country has a vast territory, long coastline, and abundant offshore wind energy resources. [0003] Offshore wind turbines must be supported on the offshore wind turbine foundation. Due to the complexity of the marine environment, the foundation cost of offshore wind turbines accounts for more than 20% of the cost of offshore wind farms. How to reduce the cost of wind turbine foundation, reduce the construction period of offshore wind turbin...
