Lattice manage, thus are restricted.Long auger method efficiency of construction is higher, without mud emission problem, but is not suitable for space
Require strict indoor construction.
Anchor jacked pile, pit static pressed pile are suitable for the indoor construction that space requirement is strict, and equipment investment is little, cost of equipment
Low, without mud emission problem, but efficiency of construction is low, is not suitable for emergent management engineering.
Foundation strengthened grouting and reinforcing be cement mortar or resinae reinforcement material are injected by pipeline according to certain pressure or
Person is infused in existing construction foundation by churning method, to ground reinforcement reinforcement.Owing to slip casting strengthening material reaches one
Fixed intensity needs the longer time, thereby increases and it is possible to occurs that in work progress building foundation produces additional settlement because of slip casting, adds
Solid lack of homogeneity away from relatively big, thus some engineering is not suitable for being suitable for.
