Waterproof roof suitable for fabricated transformer substation and construction method of waterproof roof

The invention provides a waterproof roof suitable for a fabricated transformer substation and a construction method of the waterproof roof. The waterproof roof of the fabricated transformer substation sequentially comprises a main net rack (1), a net rack supporting layer (2), a purline (3), a roof panel layer (4), an aerogel concrete layer (5) and a geopolymer concrete layer (6) from bottom to top. The waterproof roof and grid structure for the fabricated transformer substation has good applicability, attractiveness, reliability, safety and economical efficiency. The aerogel concrete is low-carbon, environment-friendly, sound-proof and heat-proof. The geopolymer concrete has high strength and large ductility, and can realize rigid waterproofing. The method has the advantages of being convenient to construct, good in anti-seismic performance, low in manufacturing cost, low in carbon and environmentally friendly, the net rack rod pieces and the nodes can be produced in batches, the efficiency is high, and the
