摘要
The change of pile cross section can increase the lateral area of pile,and pile bearing capacity can be improved.Based on this,the piles with abnormal section were developed.Because the deformation resistance capability of these casings is weak,application of these casings on construction of long piles or super-long piles is limited.The casing for the cross shaped pile is the circular steel casing with bottom wings,and has strong resistance to deformation.So,it can be used in construction of big piles,long piles or super-long piles,concrete or reinforced concrete piles,soil-squeezing piles and soil-borrowing piles,which can be used for foundation treatment,and also for construction of the foundation piles.When the special soil-borrowing devices are used for non soil-squeezing piles,quick construction,high efficient pile-forming and low cost can be able to realize.
