Grouting repair method for soluble gypsum rock stratum foundation settlement
The invention relates to a grouting repair method for soluble gypsum rock stratum foundation settlement. The grouting repair method comprises the steps that S1, the jacking treatment range of a stratum foundation is determined; s2, designing a first sequence of grouting holes and a second sequence of grouting holes, selecting survey holes, and performing drilling exploration to obtain geological information data; s3, dividing different treatment sections for the stratum depth; determining a grouting scheme of the grouting hole based on the geological information data and the processing section; s4, according to the grouting scheme, first drilling and first grouting are conducted on the positions of the first sequence of grouting holes and the second sequence of grouting holes; s5, second drilling and second grouting are conducted on the first sequence of grouting holes; s6, third drilling and third grouting are conducted on the second sequence of grouting holes; and S7, fourth grouting is conducted on the first sequence of grouting holes and the second sequence of grouting holes in sequence. Grouting lifting repair of foundation settlement is achieved through grouting hole division, treatment section division and combination of geological information data by adopting near-foundation-layer grouting protection treatment and regional and batch jacking area grouting treatment.
本发明涉及一种可溶性膏岩地层基础沉降的注浆修复方法，包括：S1、确定地层基础需顶升处理范围；S2、设计第一序列注浆孔和第二序列注浆孔，选取调查孔，钻孔勘探得到地质信息数据；S3、对地层深度划定不同处理段；基于地质信息数据和处理段确定注浆孔的注浆方案；S4、根据注浆方案，对第一序列注浆孔和第二序列注浆孔位置进行第一钻孔、第一注浆；S5、对第一序列注浆孔进行第二钻孔、第二注浆；S6、对第二序列注浆孔进行第三钻孔、第三注浆；S7、依次对第一序列注浆孔、第二序列注浆孔进行第四注浆。通过注浆孔划分，处理段划分，并结合地质信息数据，采用近基础层注浆保护处理、分区域、分批次顶升区注浆处理，实现基础沉降的注浆抬升修复。
