粉细砂地层真空注浆模拟试验研究
An Experimental Study of Vacuum Grouting in Fine Sand Layer
摘要
Abstract
A model experiment is carried out to simulate the effects of acid waterglass slurry injecting into sand under different vacuum degrees. Based on the data collected from the experiment, an analysis is made on the relations between the grouting amount and time, the grouting amount and vacuum degree, as well as grouting rate and vacuum degree. The diffusion law of acid waterglass slurry under different vacuum degrees is then summed up according to research on the grouting soil generated under conditions of-5kPa,-10kPa and-15kPa.关键词
