Combined raft foundation of outdoor framework and GIS equipment in transformer substation

Abstract

The invention provides a combined raft foundation of an outdoor framework and GIS (geographic information system) equipment in a transformer substation. Framework foundations and a GIS raft foundation form a mat foundation, wherein the burial depth of each framework foundation is increased in consideration of the load difference of the GIS equipment and a framework rod, and meanwhile, the top of the framework foundation is slightly higher than a raft so as to facilitate connection between a foundation embedded bolt and each A-shaped rod framework column. According to the invention, the top of the GIS mat foundation is elevated to the position which is as high as minus 0.3 m, and the two framework foundations and the raft foundation of the GIS equipment are arranged in a combined manner to form the mat foundation. Through adoption of the combined raft foundation, the problem of foundation collision between the framework and the GIS equipment is solved, the land occupied by the transformer substation and the foundation capacity are reduced, and the project investment is saved.

Description

technical field [0001] The invention relates to a combined raft foundation of an outdoor frame foundation in a substation and GIS equipment, and belongs to the technical field of design layout forms of a substation. Background technique [0002] Since the design of the substation adopts a unified general module, the floor area inside the wall has become a hard target that cannot be broken through. However, the foundation layout forms and foundation floor sizes required by various geological conditions are different, and the fattest natural Freestanding foundations became a tricky issue. figure 1 As shown, the outgoing line frame of the substation generally adopts an A-shaped bent frame structure. In the past, independent foundations were set up for the two columns of the A-shaped frame column in the case of natural foundations, which bear pressure and tension respectively, and meet the requirements of compression and pullout resistance; GIS equipment is The vertical loa...

Problems solved by technology

Once the general design is broken, the substation enclosure line needs to be demonstrated repeatedly and submitted to the review unit for approval. The procedure is cumbersome and it is easy to delay the construction period of the substation.
