Reinforcing and lifting method for karst foundation high-rise building
The invention discloses a reinforcing and lifting method for a karst foundation high-rise building, and relates to the technical field of building lifting. The reinforcing and lifting method comprises the following steps of shallow layer reinforcing and strengthening: firstly, performing reinforcing and strengthening treatment in rubble concrete under a building bottom plate to form a strengthening layer, and improving the compactness and rigidity of a foundation soil layer; deep-layer karst cave filling and reinforcing: after shallow-layer reinforcing and strengthening are completed, continuing downwards drilling to penetrate through a karst cave, filling and reinforcing the karst cave and a broken stone crushing zone, and forming an integral stone body; and middle-layer stable lifting: after reinforcement bodies of the upper layer and the lower layer are completed, performing pressure grouting in the stone body on the settlement side and a foundation layer between strengthening layers, continuously filling and compacting the foundation soil layer through grout, and forming lifting force on the foundation soil layer along with the increase of the pressure and the increase of the compactness, so that the building is lifted. According to the method, the building can be efficiently lifted, the process is controllable, secondary sedimentation can be effectively prevented, and the method is economical and convenient in construction.
本发明公开了一种岩溶地基高层建筑物的加固抬升方法，涉及建筑物抬升的技术领域，包括以下步骤：浅层加固补强：首先在建筑底板下毛石混凝土中进行加固补强处理，形成补强层，提高地基土层的密实度和刚度；深层溶洞填充加固：浅层加固补强完成后，继续向下施钻，穿过溶洞，对溶洞和碎石破碎带进行填充加固，形成整体的结石体；中间层稳定抬升：上下两层加固体完成后，在沉降侧的所述结石体和补强层中间地基层内进行压力注浆，通过浆液对地基土层不断的填充、挤密，地基土层随着压力的升高和密实度的增加，形成抬升力，使建筑抬升。本发明能够将建筑物高效抬升，过程可控，且能够有效防止二次沉降，经济节约，施工方便。
