摘　　要：推进绿色环保理念的实践是各行各业的目标,基坑工程作为临时性工程,特别是城市中心地带,混凝土桩+混凝土支撑大量使用,占用地下空间等遗留问题复杂,更加需要朝着绿色环保节约的方向发展。等厚水泥土墙内插型钢的支护结构施工进度快,完工后型钢可回收利用,节省成本且后期无遗留不占用地下空间,是践行绿色环保节约理念的典型;该支护结构与传统混凝土桩一样与支撑、锚相结合,可形成多种组合形式的支护结构,在复杂的城市中心地带也可因地制宜采用,具有一定的推广意义。The practice of promoting the concept of green environmental protection is the goal of all walks of life.As a temporary project,the deep excavation engineering has considerable amount of waste of resources,especially in the urban center,the large use of concrete pile+concrete support beam,the occupation of the underground space and other leftover problems are complex,so it is more necessary to forge ahead in the direction of green environmental protection and conservation.The supporting structure of the uniform thickness soil-cement mixing wall with the insertion of hot-rolled steel beams has the advantages of the fast construction progress,the recyclable hot-rolled steel beams after the completion,cost saving and minimal leftover in the later stage,and no occupation of the underground space.It is a typical example of practicing the concept of green environmental protection and conservation;Like the traditional concrete pile,the supporting structure can be combined with the support and the ground anchor to form a variety of combined support structures,which can also be adopted according to local conditions in complex urban centers,and has certain popularization significance.
