Foundation pit supporting system and construction method thereof
The invention discloses two foundation pit supporting systems, the first foundation pit supporting system comprises a top beam and a steel pile, the steel pile is sunk to the ground through a reserved beam penetrating hole in the top beam by adopting a static pile pressing machine, when the steel pile is sunk, the static pile pressing machine is detachably mounted on the top beam, and the steel pile which is sunk later is sunk to the ground by taking the steel pile which is sunk firstly as a counter-force mechanism; the second type comprises a top beam, a cast-in-place pile and a steel pile, wherein the cast-in-place pile is connected to the top beam; sinking the steel pile to the underground through the reserved beam penetrating hole in the top beam by adopting a static pressure pile machine; the steel piles are sunk through a static pressure pile machine, and when the steel piles are sunk, the cast-in-place piles serve as counter-force mechanisms to sink the steel piles to the ground; or the steel pile which sinks later sinks to the underground by taking the cast-in-place pile and the steel pile which sinks firstly as a counter-force mechanism together. The invention further discloses two construction methods of the foundation pit supporting system. The steel pile sinking in advance can serve as a counter-force mechanism, or the steel pile sinking in advance and the cast-in-place pile jointly serve as the counter-force mechanism to continue to sink the steel pile, and construction of other counter-force mechanisms on the ground is avoided.
本申请公开了两种基坑支护系统，第一种包括冠梁和钢桩，采用静压桩机将钢桩经冠梁上的预留穿梁孔被下沉到地下，下沉钢桩时，静压桩机可拆卸地安装在冠梁上，在后下沉的钢桩以在先下沉的钢桩作为反力机构下沉到地下；第二种包括冠梁、灌注桩和钢桩，灌注桩连接在冠梁上；采用静压桩机将钢桩经冠梁上的预留穿梁孔被下沉到地下；钢桩采用静压桩机下沉，下沉钢桩时，以灌注桩作为反力机构将钢桩下沉到地下；或在后下沉的钢桩以灌注桩和在先下沉的钢桩共同作为反力机构下沉到地下。本申请还公开了基坑支护系统的两种施工方法。本申请能够以在先下沉的钢桩作为反力机构、或和灌注桩共同作为反力机构继续下沉钢桩，避免在地面施工其他反力机构。
