The utility model has the following advantages that：
(1) floor space is small：Existing 500kV individual layers outlet structure single span is generally 28m, and end support span is 6m, is returned back out with 6
As a example by line framework, occupation of land total length is 180m (containing two side ends support)；And use the utility model bilayer outlet structure total length for
Occupation of land length 73m can be reduced；
(2) earthwork evacuation amount is small：The utility model bilayer outlet structure can relative to existing 500kV individual layers outlet structure
Earthwork evacuation amount is reduced, by taking 6 times outlet structures as an example, basic earthwork evacuation amount about 85m can be reduced3；
(3) body steel construction consumption is few：The utility model bilayer outlet structure is relative to existing 500kV individual layers outlet structure
Body steel construction consumption can be reduced, by taking 6 times outlet structures as an example, steel construction about 15.0t can be reduced；
