| Abstract: | There are harmful engineering phenomena of earth caves and karst caves widespread in foundation of the New Baiyun International Airport,Guangzhou,so the foundation condition is very complex.For the sake of structures' safety,in treatment of earth and karst caves a combination method of high pressure grouting and sleeved injection tube grouting is used.Through summing-up of construction method and technical demand,the main points of quality control are induced;problems likely to arise during construction are summarized and put forward treatment countermeasures as well.By the use of the com-bination method of high pressure grouting and sleeved injection tube grouting quicken the pace of engineering,re duce the en-gineering costs,but also obtain the anticipated results. |
