Transportation characteristics of paste filling material in curved pipe-line

Aiming at the problem of long-distance transportation of paste filling materials in underground pipe-lines, combined with the physical characteristics of paste filling materials, the transportation characteristics of paste filling materials in curved pipe-lines were studied by numerical simulation. The relationship between the flow resistance of paste filling materials in curved pipe-lines and the geometric size of curved pipe-lines was obtained, and the location of pipe-line damage was predicted.
