Waist support type slide-resistant pile structure construction method
The invention provides a waist support type slide-resistant pile structure construction method which comprises the following steps: (1) excavating pile holes to design positions at intervals in a to-be-supported rock-soil body behind a pile, and installing vertical piles for supporting the rock-soil body behind the pile in the pile holes; (2) a sliding body in front of the vertical piles is excavated to a stable stratum in front of the piles, and a soil retaining structure is arranged between every two adjacent vertical piles; and (3) when the sliding body in front of the vertical piles is excavated to the stable stratum in front of the piles, a plurality of supporting structures are arranged on the stable stratum in front of the piles at intervals, the supporting structures are connected with the vertical piles in a one-to-one correspondence mode, then the soil body is backfilled on the stable stratum in front of the piles to cover the supporting structures to the designed height, and the backfilled soil layer is compacted. A step-by-step construction method is adopted, the working procedures are reasonable, the construction technology is simple, operability is high, and large-scale landslide treatment, high slope reinforcement or deep foundation pit supporting can be completed within a relatively short construction period. Therefore, the structure has high practical engineering applicability.
本发明提供了一种腰撑式抗滑桩结构施工方法，包括以下步骤：(1)在需要支撑的桩后岩土体中间隔开挖桩孔至设计位置，在桩孔内安装用于支撑桩后岩土体的竖桩；(2)开挖竖桩前的滑体至桩前稳定地层，并在相邻竖桩之间搭置挡土结构；(3)当开挖竖桩前的滑体至桩前稳定地层时，在桩前稳定地层上间隔布设若干个支撑结构，各支撑结构分别与各竖桩一一对应连接，之后在桩前稳定地层上回填土体覆盖支撑结构至设计高度，并压实回填土层。本发明采用分步施工法，其工序合理，施工工艺简单，可操作性强，可在相对较短的工期内完成大型滑坡治理、高边坡加固或深基坑支护。因此，该结构具有较强的实际工程可应用性。
