Variable-width continuous beam structure and construction method thereof
The embodiment of the invention provides a variable-width continuous beam structure. The variable-width continuous beam structure comprises a middle hole beam, side hole beams and supporting pier columns. The middle hole beam is arranged above the existing line in a spanning mode, and the middle hole beam is an equal-width beam and is completed through suspension casting construction. The side hole beams are connected to the two ends of the middle hole beam, and the side hole beams are widened beams and are constructed in a cast-in-place mode. The supporting pier columns are connected to the lower portions of the ends of the middle hole beam and the side hole beams, extend in the vertical direction and are used for supporting the middle hole beam and the side hole beams. The invention further provides a construction method of the widening continuous beam structure, through the construction method combining suspended pouring and cast-in-place, the construction method can be suitable for the engineering condition that the local widening continuous beam crosses the existing line, the structural system is clear in stress, simple and reliable, and the operation safety requirement of the spanned existing line can be met under the existing construction condition.
本申请的实施例提供一种变宽连续梁结构，包括中孔梁、边孔梁及支撑墩柱；中孔梁跨设于既有线路上方，所述中孔梁为等宽梁，采用悬浇施工完成；边孔梁连接于中孔梁的两端，所述边孔梁为变宽梁，采用现浇施工完成；支撑墩柱，连接于中孔梁、边孔梁的端部下方，沿垂向延伸，用于支撑中孔梁、边孔梁。还提供变宽连续梁结构的施工方法，通过悬浇与现浇组合的施工方法，能够适用于局部变宽连续梁跨越既有线路的工程情况，结构体系受力明确，简洁可靠，且在现有施工条件下，能够满足所跨越的既有线路的运营安全要求。
