| Abstract: | In view of the problems existing in 21～23 m span steel support to set up the column pile mostly used in the present construction of the foundation pit,the article puts forward the design scheme of using the non-upright column non-uniform steel pipe support.The calculation makes clearly that the safety of the support is reliable,the technical and economical effects are more obvious,and the construction is convenient. |
