CONSTRUCTION TECHNOLOGY OF NEW FLUID FILLING MATERIAL FOR ULTRA-LONG NARROW DEEP FOUNDATION PIT
In the construction of fertilizer tank backfill,the traditional plain soil backfill technology has several"problems":the working surface of fertilizer tank is narrow,and the construction of ramming is difficult;dust problem in backfill construction;the influence of construction rain on the construction period of backfill during rainy season;after the backfill construction,the sinking phenomenon of rainwater"tamping"occurs,and the construction quality is difficult to control,and there are great security risks.A new type of backfill material is developed for the above situation,which is convenient for construction,and the material itself has the same strength and excellent stability,without obvious shrinkage,and can avoid the intangible cost increase caused by the poor quality of ordinary backfill soil,and the comprehensive benefit is significant.
