Step J：When steel jacket box (14) is transferred to design height, steel jacket box (14) surrounding bottom is surrounded with sandbag, prevents sand
Stone and sundries are flowed into when pouring bottom concrete on the inside of casing；
Step K：Concrete (13) is poured down by concrete pouring hole (5), reaches back cover by steel jacket box (14) back cover
Purpose；
Step L：It is excavated to levels junction using digging machine, the channel steel of levels reinforcing is cut off, bolt (16) is laid down, to casing
Mouth under inside drawing water to second layer waling (9) removes second layer inner support and waling (9), steel jacket box is hung out using crane piecemeal
(14)。
