Mineshaft-type underground garage deep foundation pit supporting structure
The invention discloses a mineshaft-type underground garage deep foundation pit supporting structure which is characterized in that the periphery of a foundation pit is provided with an underground cement soil continuous wall waterproof curtain; the inner side of the underground cement soil continuous wall waterproof curtain is provided with a row of rotary bored piles; the rotary bored piles are sequentially provided with a first concrete support, a second H-shaped steel combined support, a third H-shaped steel combined support, a fourth H-shaped steel combined support, a fifth concrete support, a sixth dual-spliced H-shaped steel combined support, a seventh concrete support and an eighth dual-spliced H-shaped steel combined support from top to bottom; the foundation pit is internally provided with a structural steel circuit purlin; the structural steel circuit purlin is connected with the rotary bored piles by virtue of T-shaped force transfer pieces; the periphery of the foundation pit is provided with a drainage ditch. The mineshaft-type underground garage deep foundation pit supporting structure is applicable to an ultra-deep buried underground garage deep foundation pit supporting structure, and is beneficial to excavation and rear-stage structure construction of an earthwork under the condition that the field condition is limited, and the engineering cost is saved.
