Grouting, inclination rectifying and lifting method for raft foundation building
The invention discloses a grouting, inclination rectifying and lifting method for a raft foundation building, which is characterized in that settlement monitoring points are arranged in a star shape along corresponding axes in different directions by taking a center point of the building as an original point, so that the displacement settlement condition of each point on the edge and inside of the building can be clearly reflected; the situation that the interior of the building is ignored during lifting, and consequently the raft cracks or deforms due to lifting is avoided; according to the settlement inclination condition of the building, inclined row type hole distribution is conducted, each row of lifting holes are parallel to the boundary of the main lifting area and the auxiliary lifting area, positioning of the lifting holes is more convenient, the construction progress is accelerated, and the construction efficiency is improved; according to the method, the building is subjected to regional grouting lifting, the change of the displacement value of the lifting monitoring point is observed while the building is lifted, so that the overall lifting condition and effect can be more intuitively and conveniently observed when the building is lifted, the grouting lifting process is easier to control, structural damage and slurry waste caused by excessive lifting are avoided, the construction progress is accelerated, and the construction quality is improved.
本发明公开了一种筏板基础建筑物的注浆纠倾抬升方法，本发明中沉降监测点以建筑物中心点为原点，沿着不同方向所对应的轴线进行米字型布置，能清楚反映建筑物边缘及内部各点的位移沉降情况，避免了抬升时建筑物内部被忽略而导致筏板抬裂或变形的情况；根据建筑物的沉降倾斜情况进行斜向排式布孔，每排抬升孔平行于主、次抬升区域的分界线，使抬升孔的定位更加方便，加快了施工进度，提高了施工效率；对建筑物进行分区域注浆抬升，边抬、边观察抬升监测点位移数值的变化，使得建筑物抬升时能更直观方便地观察整体抬升情况和效果，注浆抬升过程更容易控制，避免了抬升过量造成结构破坏和浆液浪费，加快了施工进度，提升了施工质量。
