Cast-in-situ bored pile deep foundation pit supporting structure and construction method thereof
The invention discloses a cast-in-situ bored pile deep foundation pit supporting structure and a construction method thereof, and relates to the field of deep foundation pit supporting, the cast-in-situ bored pile deep foundation pit supporting structure comprises a foundation pit to-be-excavated area defined by a plurality of cast-in-situ bored piles, the peripheries of the cast-in-situ bored piles are sleeved with buffer layers, and the buffer layers are used for reducing extrusion force of cast-in-situ bored pile construction; a plurality of supporting piles are arranged between the buffer layer and the cast-in-situ bored pile, are distributed in an array mode in the circumferential direction of the center of the cast-in-situ bored pile and are used for supporting the buffer layer; the elastic cloth is located between the buffer layer and the multiple cast-in-situ bored piles, the multiple supporting piles are located in the elastic cloth, and the elastic cloth wraps the cast-in-situ bored piles and is used for transmitting extrusion force of the cast-in-situ bored piles to the buffer layer; the cross beams are arranged at the pile tops of the multiple cast-in-situ bored piles; and the waterproof curtain piles are arranged on the peripheries of the cast-in-situ bored piles. By the adoption of the technical scheme, the effect of effectively reducing extrusion force generated by concrete pouring is achieved.
本申请公开了一种钻孔灌注桩深基坑支护结构及其施工方法，涉及深基坑支护领域，包括多个钻孔灌注桩合围成的基坑待挖区域，所述钻孔灌注桩外围套设有缓冲层，用于减少所述钻孔灌注桩施工的挤压力，所述缓冲层与钻孔灌注桩之间设置有多个支撑桩，多个所述支撑桩沿所述钻孔灌注桩的中心周向阵列分布，用于支撑所述缓冲层；弹性布，位于所述缓冲层与多个所述钻孔灌注桩之间，多个支撑桩位于弹性布内，弹性布包裹在所述钻孔灌注桩外，用于传递钻孔灌注桩的挤压力到缓冲层；横梁，设置在多个所述钻孔灌注桩的桩顶；止水帷幕桩围设在钻孔灌注桩外围。通过采用上述技术方案，进而实现了有效降低混凝土灌注产生的挤压力的效果。
