107国道河南新乡段马村立交至黄河大堤段交通量大,交通事故频发,被河南省交警总队列为省内20大危险路段之一。交通管理部门调查分析后认为,国道上缺少中央隔离带以及各种交通安全设施、标志,是交通事故频发的重要原因。为了有效降低交通事故率,交管部门决定在该路段中央建造中央防撞隔离墙。传统的防撞墙建造方法主要是先预制混凝土结构物,然后再进行拼装。采用这种方法施工不仅需要采用大量的人力、卡车搬运混凝土结构物,还需要用起重设备进行预制混凝土结构物的摆放。由于单个混凝土结构物很重,每 107 State Road, Xinxiang, Henan Maocun overpass to the Yellow River embankment traffic, traffic accidents, Henan Province Traffic Police Corps ranks as one of the 20 dangerous sections in the province. According to the investigation and analysis of the traffic management department, the lack of a central separation belt as well as various traffic safety facilities and signs on state roads is an important reason for frequent traffic accidents. In order to effectively reduce the traffic accident rate, the traffic control department decided to build a central anti-collision barrier in the central section of the road. Traditional anti-collision wall construction method is mainly prefabricated concrete structures, and then assembled. This method of construction requires not only the use of a large amount of manpower, truck handling of concrete structures, but also the use of lifting equipment for precast concrete structures placed. Due to the heavy weight of a single concrete structure, each
