The corresponding protruding steel bars 7 are fixedly welded to each other by butt welding.

[0046] There is a connection gap between the strip foundation beam 2 and the connection node 3 due to the mutually welded protruding steel bars 7. Secondary pouring of concrete is carried out later on the connection gap to form a post-cast strip 19, and the connection node 3 is completely connected to the strip foundation beam 2 through the post-cast strip 19.

Ensure that the protruding steel bars 7 on the outer end face of the connection node 3 correspond one by one to the protruding steel bars 7 on the two end faces of the strip foundation beam 2.

[0053] Then, the corresponding protruding steel bars 7 are welded by butt welding.

The precast holes 20 on the floor slab 1 are respectively sleeved on the protruding steel bars 7 on the upper end face of the strip foundation beam 2, and the lower end face of the floor slab 1 is in contact with the upper end face of the strip foundation beam 2. After the floor slab 1 is spliced, concrete is poured in the precast holes 20 in the later stage to ensure that the protruding steel bars 7 are completely connected with the precast holes 20 of the floor slab 1.

[0055] After the above process, the assembly foundation of the substation GIS equipment is completely assembled.
