Construction method for lifting and deviation rectification building in sludge geology
The invention discloses a construction method for lifting and deviation rectification a building in sludge geology. According to the technical scheme, the construction method comprises the following construction steps that 1, a curtain wall is formed, specifically, holes are vertically and downwards drilled in the periphery of a bottom plate of the building, and a plurality of curtain holes are formed; grouting is conducted in the curtain holes, the grouting ranges are mutually engaged and overlapped, a curtain wall is formed, and silt soil below the range of a bottom plate of a building foundation is enclosed; a water outlet is formed in the curtain wall, and the forming process of the water outlet comprises the steps that when a grout outlet of a grouting pipe moves to the position of the set water outlet, grouting is stopped; 2, lifting grouting is conducted, specifically, drilling is conducted downwards, a lifting hole is formed, pressure grouting is conducted on the bottom of the lifting hole, injected grout is rapidly solidified and continuously fills and compacts sludge in the curtain wall, and water in the sludge is discharged out of the curtain wall from the water outlet; and the compactness of the sludge in the curtain wall is increased, and lifting force is formed to lift the building. The construction method has the advantages that the building can be lifted, and secondary sedimentation can be prevented.
本发明公开了一种淤泥地质上的建构筑物抬升纠偏的施工方法，其技术方案包括以下施工步骤：步骤1、形成帷幕墙：在建构筑物底板四周竖直向下钻孔，形成多个帷幕孔；向帷幕孔内注浆，注浆范围相互咬合重叠，形成帷幕墙，将建筑物基础的底板范围以下的淤泥土进行围闭；帷幕墙上设置排水口，排水口形成过程为：注浆管的出浆口移动至设定排水口的位置时，停止注浆；步骤2、抬升注浆：向下钻孔，形成抬升孔，向抬升孔底部进行压力注浆，注入的浆液快速凝固并对帷幕墙内淤泥不断的填充、挤密，淤泥内的水分从排水口排出至帷幕墙外；帷幕墙内的淤泥密实度增加，并形成抬升力，将建构筑物抬升。本发明的优点是能将建构筑物抬升，且能防止二次沉降。
