Integrated double-layer frame type high-speed rail station widening structure and construction method thereof
The invention provides an integrated double-layer frame type high-speed railway station widening structure and a construction method thereof. The high-speed railway station widening structure comprises a plurality of non-soil-squeezing threaded piles, two top beams, a plurality of tubular pile sets, a double-layer frame structure, a filler structure, an existing roadbed and a newly-built roadbed. According to the station widening structure, the pre-stressed pipe piles and the non-soil-squeezing threaded piles are adopted for reinforcing the newly-built foundation, a passenger channel and platform integrated double-layer frame structure is used for replacing a conventional filler roadbed, and therefore the load of the newly-built roadbed can be reduced, and it can be guaranteed that an existing high-speed rail can operate safely and normally in the construction process.
本发明提供了一种一体双层框架式高铁车站拓宽结构及其施工方法，高铁车站拓宽结构包括：多根非挤土螺纹桩、两根冠梁、多组管桩组、双层框架结构、填料结构、既有路基和新建路基。在本发明中的车站拓宽结构中，通过采用预应力管桩和非挤土螺纹桩对新建地基进行加固，用旅客通道与站台一体式双层框架结构取代常规填料路基，从而既可以减小新建路基荷载，又可在施工过程中保证既有高铁安全可以正常运营。
