Construction method of deep miscellaneous fill support pile
The invention discloses a construction method of a deep miscellaneous fill support pile. The method comprises the following steps: 1, preparation before construction; 2, first-time pore-forming replacement filling is conducted on the jth front pile position in the miscellaneous fill area; thirdly, secondary hole forming is conducted on the jth front pile position in the miscellaneous fill area; fourthly, wall protection and pile forming are conducted on the jth front pile position in the miscellaneous fill area; fifthly, the next supporting pile is constructed at the (j + 2) th front pile position till construction of the front pile positions with the odd numbers in the first row of pile positions is completed; sixthly, construction of the front pile positions with the even numbers in the first row of pile positions is completed in sequence; seventhly, support pile construction is conducted from the first rear pile position to the J'th rear pile position in sequence till construction of the second row of pile positions is completed; and 8, constructing a supporting structure of the miscellaneous fill side wall. The method is simple in step, reasonable in design and convenient to construct, reinforcement of the miscellaneous fill layer is achieved, cost is saved, safety is improved, the construction speed is increased, and miscellaneous fill supporting can be easily, conveniently and rapidly completed.
本发明公开了一种深杂填土支护桩施工方法，该方法包括以下步骤：一、施工前准备；二、杂填土区域第j个前桩位的第一次成孔换填；三、杂填土区域第j个前桩位的第二次成孔；四、杂填土区域第j个前桩位的护壁及成桩；五、在第j+2个前桩位进行下一个支护桩施工，直至完成第一排桩位中编号为奇数的前桩位的施工；六、依次完成第一排桩位中编号为偶数的前桩位的施工；七、在第1个后桩位至第J′个后桩位依次进行支护桩施工，直至完成第二排桩位的施工；八、杂填土侧壁的支护结构施工。本发明方法步骤简单，设计合理且施工便捷，以实现杂填土层的加固，节约了成本，且提高了安全性和施工速度，能简便、快速完成杂填土支护。
