Technical field
The utility model relates to a kind of construction pile foundations, and in particular to skirt piles are gone along with sb. to guard him in a kind of buried subway station PBA.
Background technique
The principle of cavern-pile method (" PBA ", i.e. stake Pile, beam Beam, arch Arc) is exactly by traditional ground frame structure construction
Method and subsurface excavation method are organically combined, i.e., when not having construction foundation pit building enclosure condition on the ground, change into underground and shift to an earlier date
It is applied in the good pilot tunnel of tunneling and goes along with sb. to guard him skirt piles, center pillar, bottom beam and top beam, crown, collectively form stake, beam, arch brace frame system,
The external loads for bearing work progress successively excavate downwards the soil body then under the protection of crown and skirt piles, internal junction of constructing
Structure ultimately forms the permanent carrying system being composed of outer layer skirt piles and crown preliminary bracing and two lining cutting of internal layer.
Existing PBA (i.e. Underground Subway Station cavern-pile method) skirt piles construction method are as follows: the setting-out of stake position is first carried out, according to setting-out position
It sets and carries out first segment earth excavation, first segment excavation height can be determined according to stake diameter and geological condition, according to design drawing size
After the completion of earth excavation, the binding of retaining wall reinforcing bar is carried out, then carries out formwork erection, and pour breast wall concrete；First segment retaining wall coagulation
After soil pours, installed artificial digging pile vertical hoisting system (generally using electric block, hoist engine or winch) at hole hole, the
Two section earth excavations are until stake bottom earth excavation is completed the artificial digging pile waste that earth excavation is formed by vertical hoisting system
Transport, and the binding of retaining wall reinforcing bar and applying of pouring of breast wall concrete are carried out according to design requirement according to the progress of earth excavation
Work is until stake bottom；Pore-forming examination is finally carried out, pile body steel reinforcement cage is bound after acceptance(check) and pours pile body concrete.
By above-mentioned construction method skirt piles obtained, structural strength is poor, to influence whether subsequent construction.
