桥梁防撞墙作为桥梁的附属结构,是一种重要的安全防护物,现有技术中的桥梁防撞墙通常是采用现浇法施工,由于桥梁防撞墙通常是在梁体施工完成后现场浇筑,采用现场施工的桥梁防撞墙通常需要安装内侧模板和外侧模板,并在两者之间浇筑混凝土以形成防撞墙,然而模板安装工艺较复杂,需要辅助安装设备,工期长、工效低,易发生跑模现象,从而导致防撞墙凹凸不平,影响桥梁外观。
As an auxiliary structure of the bridge, the bridge anti-collision wall is an important safety protection. In the prior art, the bridge anti-collision wall is usually constructed by cast-in-situ method. Since the bridge anti-collision wall is usually cast on site after the beam construction is completed, the bridge anti-collision wall constructed on site usually needs to be installed with inner formwork and outer formwork, Concrete is poured between the two to form the anti-collision wall. However, the formwork installation process is complex, auxiliary installation equipment is required, the construction period is long, the work efficiency is low, and it is easy to run the formwork, resulting in the unevenness of the anti-collision wall and affecting the appearance of the bridge.
结合城市建设的快速化、节约型发展的需求,装配式防撞墙的研究和应用成为一项新的课题。目前对于防撞墙的预制结构的研究应用主要包括防撞墙与梁体结构在预制厂内整体预制、采用螺栓连接安装方式的预制防撞墙型式,以及目前正在研究的后浇带连接方式的预制结构型式。
Combined with the rapid and economical development of urban construction, the research and application of prefabricated anti-collision wall has become a new topic. At present, the research and application of the prefabricated structure of the anti-collision wall mainly includes the overall prefabrication of the anti-collision wall and the beam structure in the prefabrication plant, the prefabricated anti-collision wall type with bolt connection installation, and the prefabricated structure type with post cast strip connection under research.
