Concrete simply-supported small box girder road butt joint construction process
The invention belongs to the technical field of road construction, and particularly relates to a concrete simply-supported small box girder road butt joint construction process which comprises the following steps: S1, manufacturing a bottom die: transversely paving No.16 channel steel with the same width as a box bottom on the basis of an original foundation concrete surface layer (the surface layer adopts a steel plate with the thickness of 1cm) in a site, longitudinally laying a gear of No.16 channel steel on the No.16 channel steel with the same width as the bottom of the box at an interval of 30 cm to form a bottom die; s2, manufacturing steel bars: keeping the surfaces of the steel bars clean and straight, and arranging a shaping jig frame in a precast beam field. according to the concrete simply-supported small box girder road butt joint construction process, the concrete simply-supported small box girders are arranged for butt joint of the roads, the problem that a railway and an expressway transversely penetrate through the whole Songjiang main urban area and obstruct axial road traffic transportation of the main urban area is effectively solved, outward development of a city is fused with space of surrounding areas, and the collecting and distributing functions of the road network are fully exerted.
本发明属于道路施工技术领域，尤其是一种混凝土简支小箱梁道路对接施工工艺，包括以下步骤：S1、底模制作，在场地内原有基础混凝土面层(面层采用1cm厚钢板)的基础上横向铺设与箱底同宽的16号槽钢，在横向铺设与箱底同宽的16号槽钢的上面纵向每间隔30cm铺设一档16号槽钢，形成底模；S2、钢筋制作，保持钢筋表面洁净、平直，预制梁场内配置定型胎架。该混凝土简支小箱梁道路对接施工工艺，通过设置混凝土简支小箱梁对道路进行对接，有效解决了由铁路和高速公路横穿整个松江主城区，对主城区轴向道路交通运输的阻碍，使得城市的对外发展与周边区域的空间融合，充分发挥路网的集散功能。
