Construction method of supporting structure suitable for stretching across foundation pit pipeline group and supporting structure suitable for stretching across foundation pit pipeline group
The invention discloses a construction method of a supporting structure suitable for stretching across a foundation pit pipeline group. The construction method comprises the following steps of constructing an enclosure structure around the foundation pit; constructing two first reinforced concrete supports and temporary stand columns nearby an underground pipeline group to be migrated; conductingslope excavation of earthwork nearby the underground pipeline group to be migrated in the foundation pit; when excavation reaches the position 0.5 m lower than the elevation of the bottom of the underground pipeline, manually clearing the base and using plain concrete for leveling; clearing muck around the temporary stand columns; laying reinforcing meshes on a plain concrete cushion layer, pouring concrete and maintaining the concrete to a designed strength; migrating the underground pipeline group to a reinforced concrete structure board; excavating the foundation pit; constructing an underground structure; and conducting backfilling on the foundation pit on the periphery of the underground pipeline group. The construction method has the advantages that operation is easy and convenient,and the structure is firm. The invention further discloses the supporting structure used for stretching across the foundation pit pipeline group and constructed by the adoption of the construction method of the supporting structure suitable for stretching across the foundation pipe pipeline group.
本发明公开了一种适用于横跨基坑管线群的支撑结构的施工方法。它包括如下步骤，施工基坑四周的围护结构；施工拟改迁地下管线群附近的两根第一道钢筋混凝土支撑和临时立柱；放坡开挖基坑内拟改迁地下管线群附近的土石方；开挖至地下管线群底部标高以下0.5m时，人工清理基底，并采用素混凝土找平；清理临时立柱周边的渣土；在素混凝土垫层上铺设钢筋网片，浇筑混凝土并养护到设计强度；将地下管线群改移到钢筋混凝土结构板上；开挖基坑；地下结构施工；回填地下管线群周边基坑。本发明具有操作简便，结构稳固的优点。本发明还公开了采用适用于横跨基坑管线群的支撑结构的施工方法施工的用于横跨基坑管线群的支撑结构。
