Post-grouting miniature steel pipe pile building or structure deviation rectifying and reinforcing construction method
The invention discloses a post-grouting miniature steel pipe pile building or structure deviation rectifying and reinforcing construction method. The post-grouting miniature steel pipe pile building or structure deviation rectifying and reinforcing construction method is technically characterized in that a drainage sinking promoting and reinforcing jacking method is combined for use, an electromagnetic field method or an electromagnetic field and thermal consolidation combined method is adopted for performing drainage sinking promoting on the side, with small settlement, of a building or a structure, and a post-grouting screw pile method is adopted for reinforcing and jacking the side, with large settlement, of the building or the structure. Water drainage and settlement promotion of a soil body are accelerated through the electromagnetic field method or the electromagnetic field and thermal consolidation combined method, and the construction period is shortened; and grouting jacking and drainage settlement promotion are combined, and deviation rectification and reinforcement can be effectively carried out on soft soil foundation buildings or structures. The construction cost is low, the period is short, the construction process is simpler, and the application range is wider.
本发明公开一种后注浆微型钢管桩建筑物或构筑物纠偏与加固施工方法，其技术特征在于，联合运用排水促沉和加固顶升的方法，采用电磁场法或电磁场联合热固结法对建筑物或构筑物沉降较小一侧进行排水促沉，采用后注浆螺旋桩法对建筑物或构筑物沉降较大一侧进行加固和顶升。本发明通过电磁场法或电磁场联合热固结法加速土体排水促沉，缩短工期；注浆顶升与排水促沉相结合，可以有效地对软土地基建筑物或构筑物进行纠偏与加固。本发明施工成本较低、周期较短、施工工序更加简易、应用范围更广。
