Forest type excavation construction method for subway station
The invention provides a forest type excavation construction method, and relates to the field of civil engineering, in particular to the field of subway station construction engineering. The forest type excavation construction method mainly comprises the following steps that a) a flat tree-shaped supporting structure is arranged in a long and narrow gap zone of an existing underground pipeline (2); b) the flat tree-shaped supporting structure is placed below the pipeline and then is mixed with cement and rotates; c) a soil body is jointly supported by the flat tree-shaped supporting structureand cement soil; d) the soil body is excavated, and a main body structure (6) of the underground station is constructed; and e) the main body structure (6) bears a load, and a tree-shaped force transmission structure (5) is cut off. According to the forest type excavation construction method, large-scale pipeline migration in urban subway station construction can be avoided, the construction period can be greatly shortened, and the influence of urban subway construction on urban traffic and environmental sanitation is greatly reduced.
本发明涉及土木工程领域地铁车站建造工程领域中的一种森林式开挖施工方法，主要包括以下步骤：a)在已有地下管线(2)狭长形空隙带中布设扁平树形支撑结构；b)将扁平树形支撑结构置入管线下方后掺拌水泥旋转；c)由扁平树形支撑结构与水泥土共同支撑土体；d)开挖土体，施工地下车站的主体结构(6)；e)由主体结构(6)承担荷载，切除树杆状传力结构(5)，本发明可避免城市地铁车站建设中大规模管线动迁，可大幅度缩短建设周期，大幅度减少城市地铁建设对城市交通与环境卫生的影响。
