Construction method for reserving bridge expansion joint
The invention relates to the technical field of bridge engineering, in particular to a construction method for reserving a bridge expansion joint, which comprises the following steps of: filling a gap between a first box girder and a second box girder with a rubber foaming plate, performing a bridge floor reinforced concrete construction process, and forming a reserved notch above the first box girder and the second box girder; then laying isolation layers on the bottom and the side wall of the reserved notch, after a sand cushion layer is formed in the reserved notch, carrying out paving and rolling of an asphalt surface layer according to requirements, then cutting along the reserved notch through a concrete cutting machine, cleaning the reserved notch after cutting, and therefore creating conditions for bridge expansion joint installation. The construction method is simple, high in efficiency, low in construction cost and capable of meeting the operation requirements of continuously paving asphalt and ensuring the rolling compaction degree.
本发明涉及桥梁工程技术领域，具体为一种预留桥梁伸缩缝的施工方法，通过在采用橡胶发泡板填充第一箱梁和第二箱梁之间的缝隙后，进行桥面钢筋混凝土的施工工艺，并于第一箱梁和第二箱梁之上形成预留槽口，然后在预留槽口底部及侧壁铺设隔离层，并在于预留槽口内形成砂垫层之后，按要求进行沥青面层的摊铺和碾压，之后采用混凝土切割机沿预留槽口缝进行切割，完成后进行预留槽口清理，从而为桥梁伸缩缝安装创造条件。该施工方法简单，效率高，施工成本低，能够满足沥青连续摊铺并保证碾压压实度的作业需求。
