Pile-slab roadbed structure of underneath passing railway bridge highway and construction method thereof
The invention provides a pile-slab roadbed structure of an underneath passing railway bridge highway and a construction method thereof, a group of cast-in-place concrete piles are arranged below a railway bridge and on two sides of the railway bridge at certain intervals along the longitudinal direction of the highway, and each group of cast-in-place concrete piles is a certain distance away from a railway bridge foundation; continuous concrete beams and slabs are longitudinally arranged at the tops of the concrete cast-in-place piles along the highway, the beams and the tops of the concrete cast-in-place piles are poured into a whole, and a certain height exists between the bottom faces of the two sides of the beams and the top face of the railway bridge foundation. A pile plate type continuous rigid frame structure is adopted, a certain distance is formed between the pile plate type continuous rigid frame structure and a railway pier foundation, pressure is not increased on the railway pier foundation, the influence on settlement deformation of an existing structure is almost zero, and the operation safety of a railway bridge can be guaranteed; the roadbed structure is low in height, and it can be guaranteed that the effective clearance from the pavement to the bottom of the railway bridge meets the operation requirement.
本发明提供一种下穿铁路桥公路的桩板路基结构及其施工方法，沿公路纵向在铁路桥下方及铁路桥两侧每隔一定间距设有一组混凝土灌注桩，每组混凝土灌注桩距铁路桥基础有一定距离，各组混凝土灌注桩顶部沿公路纵向设有连续的混凝土梁板，梁板与混凝土灌注桩顶部浇筑为一体，梁板的两侧底面距铁路桥基础顶面有一定高度。本发明采用桩板式连续刚架结构，与铁路桥墩基础有一定距离，对铁路桥墩基础不增加压力，对既有结构沉降变形影响几乎为零，能保证铁路桥运营安全；路基结构高度较低，可有保证路面至铁路桥梁底的有效净空符合运营要求。
