Construction system and method for cast-in-place box girder support of soft foundation area urban railway
The invention discloses a construction system and method for a cast-in-place box girder support of a soft foundation area urban railway. The problems that in existing box girder construction, damage to a foundation is large, and sedimentation is prone to occurring are solved. The system comprises a bearing platform, a plurality of stand columns are arranged on the bearing platform, every two adjacent stand columns are connected through a diagonal bracing, each stand column is provided with a movable head and a lifting mechanism, the lifting mechanisms are connected with the movable heads and used for adjusting the horizontal height of the movable heads, the movable heads are provided with bailey beams, and the bailey beams are provided with steel molds facilitating cast-in-place of box girders. The construction method comprises the steps of constructing the cast-in-situ bored piles, constructing the bearing platform, arranging the bailey trusses and constructing the cast-in-situ box girder. The system also has the advantages of simple structure, convenience in assembly, long service life and the like.
一种软基地区市域铁路现浇箱梁支架的施工系统及施工方法。解决现有箱梁施工时对地基破坏大，容易沉降的问题。它包括承台，所述的承台上设有多根立柱，相邻的两根立柱之间通过剪刀撑相连接，每个立柱上均设有活络头和升降机构，所述的升降机构与活络头相连并用于调整活络头的水平高度，所述的活络头上设有贝雷梁，所述的贝雷梁上设有便于现浇箱梁的钢模。施工方法包括施工钻孔灌注桩、施工承台，设置贝雷桁架及现浇箱梁进行施工。本发明还具有结构简单，装配方便，使用寿命长等优点。
