Construction method for high-rise building settlement reinforcement lifting deviation rectification
The invention relates to a construction method for high-rise building settlement reinforcement lifting deviation rectification. The construction method comprises the following steps that holes are vertically drilled downwards around a building bottom plate to form a plurality of curtain holes penetrating into foundation soil at intervals; grouting is conducted in the curtain holes, the grouting ranges are mutually meshed and overlapped to form a curtain wall, and the curtain wall encloses foundation soil below the bottom plate of the building foundation and isolates the foundation soil insideand outside the building range; a plurality of vertical reinforcing grouting holes are formed in the bottom plate, grouting is conducted, the soil body close to the bottom plate is completely reinforced, and a reinforcing body is formed; and downward drilling is conducted to form a lifting hole, the lifting hole goes deep into the bottom of the reinforcing body, pressure grouting is conducted on the bottom of the lifting hole, foundation soil is continuously filled and compacted along with continuous increase and rapid solidification of grout in the curtain wall, lifting force is formed, and the building is gradually lifted to the set lifting height. The construction method has the effects that the building can be effectively lifted, and secondary sedimentation can be prevented.
本发明涉及一种高层建筑沉降加固抬升纠偏的施工方法，其包括以下步骤：在建筑物底板周围竖直向下钻孔，形成多个间隔的深入地基土的帷幕孔；向帷幕孔内注浆，注浆范围相互咬合重叠，形成帷幕墙，所述帷幕墙将建筑物基础的底板以下的地基土进行围闭，并将建筑物范围内外的地基土隔离；在底板上开设多个竖向的加固注浆孔，并进行注浆，将靠近底板的土体全部加固，形成加固体；向下钻孔，形成抬升孔，抬升孔深入至加固体的底部，向抬升孔底部进行压力注浆，随着帷幕墙内浆液的不断增加并快速凝固，地基土不断被填充、挤密，并形成抬升力，建筑物逐渐抬升至设定的抬升高度。本发明具有能够有效地将建筑物进行抬升，并能够防止二次沉降产生的效果。
