摘　　要：昆明春之眼商业中心副塔楼筏板基础浇筑量达1.4万m^3混凝土,为保证连续有效高效地浇筑混凝土,在基坑狭窄空间内采用可移动式分支溜槽.可移动式分支溜槽施工效率高,适用范围广,节约了固定式溜槽分支搭设的成本,又避免了混凝土浇筑不连续带来的质量问题.The annex tower building of Kunming Chunzhiyan (Eye of Spring) Commercial Center has a raft foundation with 14000 m^3 concrete placing volume. To guarantee continuous and effective concrete placing, removable bypass chute was used for narrow spaces in the foundation pit. The removable bypass chute has high construction efficiency and wide application scope, not only saving the construction cost of fixed bypass chute installation, but also avoiding quality problems due to discontinuous concrete placement.
