Preferably, the steel-concrete layer comprises steel bars, concrete and broken stones.

Preferably, the original soil layer is C15 plain concrete.

Has the advantages that:

firstly, a plurality of steel casing drums are dug down to the ground, accumulated water and soft soil in the steel casing drums are pumped out, so that a cylindrical cavity is formed in the steel casing drums, then an original soil layer and a reinforced concrete layer are sequentially injected into the steel casing drums, and when the reinforced concrete layer is poured, embedded steel pieces are embedded into the reinforced concrete layer, so that the embedded steel pieces and the reinforced concrete layer form a whole; at the moment, a stable bottom framework can be obtained, and then a stable lake gallery road structure is built through the I-shaped steel, the purlins, the pineapple lattice anti-corrosion wood transverse plates and the pineapple lattice anti-corrosion wood upright posts.

Compared with the traditional mode of evacuating lakes or constructing temporary cofferdams, the method has the advantages of short construction time, low damage to ecology and suitability for development and construction of plateau lake scenic spots. And through the mode of building former soil layer and steel-concrete layer matched with in the inside of steel protects a section of thick bamboo, compare with directly building former soil layer and steel-concrete layer, the degree of depth that its ground founded is darker, and holistic structural stability is better.
