Abstract：
In the column construction of ZTE Nanjing Research and Development Center No.1 Building, high-density polyethylene double-wall corrugated tubes with same diameter are used for formwork, which has smooth inner wall, high strength, light weight and annular corrugated outer wall. The pipe rigidity is increased obviously to avoid deformation; two semicircles are connected together to reduce the number of joint and to improve the forming quality of concrete after the formwork is removed. Compared with same type of typified steel formwork, the corrugated tube formwork has lower cost, more convenient construction and better economic benefit.
