激光摊铺技术在京沪高速公路桥面铺装中的应用

Application of laser paving technology in bridge deck paving of Beijing-Shanghai expressway

全自动桁架式辊轴激光摊铺机,由光发射和接收设备、辊轴桁架、液压行走设备组成,用于高速公路大桥的混凝土整幅铺装以及混凝土地面、路面的施工,使混凝土摊铺的振捣、提浆、整平的效果更好,相比以往人工找平、抹面施工和传统混凝土摊铺机施工自动化程度提高,从而节约劳动力,降低施工成本。以京沪高速改扩建工程邳苍分洪道特大桥为例,对该技术进行了介绍。

The full-automatic trussed roller laser paver is composed of light transmitting and receiving equipment,roller trusses and hydraulic walking equipment,which is used for the whole concrete paving of expressway bridge and the construction of concrete floor and pavement.Compared with manual leveling,plastering and traditional concrete paver construction,the full-automatic trussed roller laser paver helps improving the effect of vibration,slurry lifting and leveling of concrete with higher degree of automation construction,which also plays an important role in cost controling.The paper takes the reconstruction and expansion project of Beijing-Shanghai expressway Picang Fenhong road bridge as an example,introduces the application of automatic paving technology.
