Foundation drilling synchronous grouting jacking implementation method for building deviation correction
The invention discloses a foundation drilling synchronous grouting jacking implementation method for building deviation rectification, which comprises the following steps of: measuring the settlement displacement of each point position of a masonry structure building to be rectified, and arranging an elevation observation point; designing a deviation rectifying scheme, calculating a building design jacking value of each point position, and determining foundation drilling plane positioning, elevation and drilling direction; excavating earth at the periphery of the building below a foundation drilling point, and drilling the foundation and taking soil at the lower part of the raft foundation according to the set drilling point position and direction; drilling equipment is taken out, a long steel pipe is selected to be sleeved with an expandable sealing fiber bag, and the long steel pipe is plugged into a drilled hole; pressure grouting is conducted on all the expandable sealing fiber bags; and grouting is stopped, the foundation hole in the side where the grouting opening is located is blocked, and the excavated earthwork is backfilled.
本发明公开了一种用于建筑物纠偏的地基钻孔同步注浆顶升实施工法，该方法为：测量待纠偏砌体结构建筑各点位沉降位移，设高程观测点；设计纠偏方案，计算各点位建筑设计顶升值，确定地基钻孔平面定位、标高及钻孔方向；建筑物外围土方开挖至地基钻孔点以下，在筏板基础下部按设定的钻孔点位置及方向进行地基钻孔并取土；取出钻孔设备，选用长钢管在外围套上可膨胀密封纤维袋并塞入已钻好的孔洞；对所有可膨胀密封纤维袋进行压力注浆；停止注浆，并封堵注浆口这一侧的地基孔洞，回填开挖的土方。
