Reserve embedded postposition construction method of switch gear room of transformer substation

A reserve embedded postposition construction method of a switch gear room of a transformer substation mainly comprises the following steps of construction preparation of a base layer, levelling, floor maintenance and placement of embedded pieces. By the reserve embedded postposition construction method of the switch gear room of the transformer substation, a construction technology, which is synchronous to main construction, of traditional reserve embedded construction of the switch gear room of the transformer substation and a cable interlayer is modified into reserve embedded postposition hole and groove forming. The technology of embedded iron pieces constructed by a postposition method is simple, construction positioning is accurate, elevation is controlled in place, any objects projected out of a plate surface do not exist, operation is easy in a construction process, elevation of the plate surface is also easy to control, and time and labor cost are saved. During mounting of reserved holes, form boards for forming the holes are not required, labor and time are saved, errors are not easy to cause during positioning, and a plane view size cannot deform easily. The whole technology is attractive, the time is saved, the cost is reduced, later hole blocking workload is reduced, and the number of hole cover plates is reduced.
