Concrete is leaked in lower floor's solution cavity area cavity when stake is cast-in-place.
The steel reinforcement cage of F lifting deposited reinforced concrete piles enters stake holes, and placing concrete forms cast-in-place concrete pile, and makes to mix
Solidifying soil pours into hypomere stake hollow section and carries out filling out core, while by joint steel reserved at the top of the concrete tubular pile as hypomere stake
Muscle, concrete tubular pile and deposited reinforced concrete pile is set to be combined into an overall common stress of pile body.
As an improvement, the gas-flow closure circle replaces with flexible rubber seal.
Preferably, hypomere stake hollow section carries out filling out core and epimere stake is poured while carried out.
The present invention has following advantages and effect compared with prior art:The steel reinforcement cage and concrete of epimere stake stretch into down
Section pile tube suitable length, makes epimere stake and hypomere stake be combined into an overall common stress of pile body, easy for construction, quick.Hypomere
Pile body is concrete precast pipe pile, construction when without again in solution cavity throwing slabstone formed retaining wall or use steel pile casting retaining wall, saving
Solution cavity area steel pile casting expense or throwing slabstone long construction period shortcoming in current conventional method, have speed of application fast, make
The advantages such as valency is low.The present invention conventional stake in solution cavity area is replaced with concrete tubular pile, while the concrete tubular pile and can with below
The bored concrete pile of construction is combined into the common stress of permanent structure, therefore is a kind of economical and practical piling strtucture, and economic benefit will be non-
Chang Mingxian.
