Deviation rectifying method for existing building
The invention relates to the field of uneven settlement and lateral displacement treatment of structures, in particular to a deviation rectifying method for an existing building. The method comprises the following steps: excavating a plurality of test pits in an empty ground near the existing building, and obtaining a relationship between different mass ratios n and single-side deformation delta L; investigating and measuring lateral deformation of the existing building, and determining recovery deformation required by different depths of the existing building according to design requirements; determining the mass ratio of the expansion cement paste required by different depths in the cutting groove according to the recovery deformation required by different depths of the existing building; cutting grooves are formed; according to the mass ratio of the expansion cement paste required by different depths in the cutting groove, the expansion cement paste is poured in the cutting groove in a layered mode; and sealing the top of the cutting groove at a first height from the ground, and finishing deviation correction after the expansion cement paste is hardened. The embodiment of the invention provides a deviation rectifying method for an existing building. The deviation rectifying method is used for solving the problem that in the related technology, grouting jacking cannot avoid damage to soil near the building.
本申请涉及构筑物不均匀沉降及侧移处理领域，特别涉及一种既有建筑的纠偏方法。该方法包括以下步骤：在既有建筑附近空地处开挖多个试验坑，获取不同质量比n与单侧变形量ΔL的关系；调查量取既有建筑的侧向变形量，按照设计要求确定既有建筑不同深度所需的恢复变形量；根据既有建筑不同深度所需的恢复变形量，确定切槽内不同深度所需的膨胀水泥浆的质量比；开设切槽；根据切槽内不同深度所需的膨胀水泥浆的质量比，在切槽内分层浇筑膨胀水泥浆；在切槽距地面第一高度处进行封顶，待膨胀水泥浆硬化完成后结束纠偏。本申请实施例提供了一种既有建筑的纠偏方法，以解决相关技术中注浆顶升不能避免对构筑物附近土壤造成损坏的问题。
