Method for reinforcing soft soil foundation through bagged sand wells
The invention discloses a method for reinforcing a soft soil foundation by using a bagged sand well, which comprises the following steps of: leveling an original ground to be constructed in a set area, and then paving a lower sand cushion layer; setting the hole position, depth, diameter and spacing of the sand well, sinking the well pipe into the ground, putting a cylindrical sand bag into the well pipe, then pulling up the well pipe, filling the sand bag into the hole to form the sand well, and then laying a sand cushion layer; observation sections are arranged every 200 m, and settlement observation plates and displacement observation side piles are arranged on the observation sections; filling of embankment earthwork is conducted on the upper sand cushion layer, and the filling rate of the embankment earthwork is controlled according to the horizontal displacement rate and the sedimentation rate; when the horizontal displacement rate and the settlement rate exceed set values, filling of the embankment earthwork is stopped, and filling is conducted after the horizontal displacement rate and the settlement rate are recovered to be below the set values; and then treating the embankment by adopting an overload pre-pressing method. The problems that in the prior art, the foundation strength is poor, the bearing capacity is poor, and the foundation is prone to sedimentation are solved, and reinforcement of the soft soil foundation is achieved.
本申请公开了一种利用袋装砂井加固软土地基的方法，包括以下步骤：整平设定区域待施工的原地面，然后铺设下砂垫层；设置砂井的孔位、深度、直径和间距，将井管沉入地下，在井管内放入圆柱形的砂袋，然后拔起井管，砂袋充填在孔中并形成砂井，然后铺设上砂垫层；每隔200m设置一个观测断面，在观测断面设置沉降观测板和位移观测边桩；在上砂垫层进行路堤土方的填筑，根据水平位移速率和沉降速率控制路堤土方的填筑速率；水平位移速率和沉降速率超出设定值时，停止路堤土方的填筑，待恢复到设定值以下再进行填筑；然后采用超载预压法处理路堤。本申请解决了现有技术中地基强度差、承载力差、以及地基容易沉降等问题，实现了软土地基的加固。
