Combined foundation of framework compressed column and enclosure in transformer substation

Abstract

The invention provides a combined foundation of a framework compressed column and an enclosure in a transformer substation. A framework foundation and the lower part of a lower barricade foundation of the enclosure are arranged in a combined manner and are integrally cast to form the combined foundation. In order to avoid affecting respective use functions, an A-shaped rod framework column is reliability connected with the combined foundation through an embedded bolt on one side of the combined foundation, and in consideration of the overall vertical face effect outside the enclosure and the smooth water drainage inside and outside the substation, the appearance of the part, exposed out of the ground, of a barricade and other barricades are processed uniformly on the other side of the combined foundation, and construction column expansion joints are arranged at two ends of the combined foundation to enable the two ends of the combined foundation to be separated from other enclosures to avoid cracking of a wall body; the integrally cast foundation bears the loads of a compressed framework and the enclosures at the same time, so that safety and reliability are achieved, the size between the framework and each enclosure is reduced, the effective stress of an enclosure foundation is reduced, the project investment is saved, and the construction is convenient.

Description

technical field [0001] The invention relates to a combined foundation of a frame pressure column and a surrounding wall in a substation, and belongs to the technical field of substation infrastructure construction. 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 upper part of the outgoing line frame in the substation generally adopts an A-shaped bent frame structure. In the past, an independent foundation was set up for the two columns of the A-shaped pole when the natural foundation was used. The compression is the most unfavorable, and the side column foundation close to the equipment in the station is the most unfavorable fo...

Problems solved by technology

Once the wall of the general design substation is broken through, repeated demonstrations and explanations are required and approval by review units at all levels is required. The procedure is cumbersome and affects the progress of the project
