Claim 4:
5. The method for filling deformable karst cave according to claim 4, wherein filling steps of the filling material are as follows:
(1) dividing the silicate resin into two groups: A and B, wherein in group A, a viscosity is 300 cp, and a density is 1500 g/cm3, and in group B, a viscosity is 135 cp, and a density is 1200 g/cm3, and injecting groups A and B into the elastic silicone tube after being mixed at a volume ratio of 1:1; and
(2) mixing the steel fiber and the grout in a 1:10 mass ratio to obtain a mixture, then uniformly stirring and injecting the mixture into the elastic silicone tube to complete the filling.
