Advanced mixing pile inclined pile foundation pit supporting construction process
The invention provides an advanced mixing pile inclined pile foundation pit supporting construction process. The advanced mixing pile inclined pile foundation pit supporting construction process mainly comprises the following steps of S1, surveying and setting out, specifically, marking the positions of angular points of a mixing pile on site, setting out the position of a driving point of an inclined pile, and checking; S2, supporting pile construction; S21, construction of a three-axis mixing pile; S22, inclined pile construction, specifically, vibration pile sinking; S23, crown beam construction and inclined pile pouring joint, specifically, after inclined pile construction is finished, the crown beam starts construction, and meanwhile, inclined piles are poured into the crown beam; andS24, earth excavation and cushion layer construction are conducted, specifically, after the batter piles and the top beam are constructed and reach the designed strength of 80%, earth excavation is conducted. By means of the mode, the problems of parallel supporting, inclined throwing supporting, piled anchors and self-stabilization type foundation pit supporting defects in an existing safety level second-level area can be solved.
本发明提出了一种超前搅拌桩斜桩基坑支护施工工艺，主要包括如下步骤：S1、测量放线：在现场标注出搅拌桩的角点的位置，同时放样出斜桩打入点的位置，并进行校核；S2、支护桩施工；S21、三轴搅拌桩施工；S22、斜桩施工：振动沉桩；S23、冠梁施工及斜桩浇筑节点：在斜桩施工结束后，冠梁启动施工，同时将斜桩浇筑在冠梁中；S24、土方开挖及垫层施工：在斜桩及冠梁施工后，到达设计强度80％后，土方开挖。通过上述方式，本发明能够解决现有在安全等级二级区域平行支撑、斜抛撑、桩锚以及自稳式基坑支护的不足的问题。
