        資料簡介

        第一卷 水泥砼路面機械攤鋪
            1特點
            1.1本工法采用螺旋布料器布料、多根振動棒振動密實、振搗器上下振搗壓入粗骨料、成型模板擠壓成型和抹光等工序,確保了水泥混凝土路面密度,特別是路面的平整度有了明顯的提高,能滿足高等級道路、機場飛行區等工程的高標準質量要求。
            1.2攤鋪施工過程全部自動化,采用電動液壓控制系統、傳感器控制轉向和升降,它集水泥混凝土的布料、攤鋪、密實、成型和抹光等功能,使水泥混凝土路面一次成型。并且還能適應不同寬度(3.66~9.75m)和不同厚度(最大厚度可達48.3cm)的水泥混凝土路面施工要求,攤鋪速度根據混凝土的供料速度而定。
            1.3在攤鋪過程中,輔以人工配合,能按設計要求在水泥混凝土路面中間或兩側邊自動打入鋼筋傳力桿。
            2適用范圍
            適用于水泥混凝土類的高等級公路、城市道路、機場飛行區、集裝箱堆場和廣場地坪等工程。
            3工藝原理
            水泥混凝土路面滑模式攤鋪機工藝原理如下圖所示:
         
        通過螺旋布料器(包括二次布料器)均勻布料,振動棒和振搗器的振實,經滑模板滑出成型,最后由抹光板搓柔整修表面。
            4施工工藝
        在驗收合格的基層或對基層進行整修合格后,進行攤鋪基準
        Volume of cement concrete pavement paving
            1 Features
            1.1 The Public Law spiral cloth fabric devices, and more dense root vibration vibrator, vibrators vibrating pressure down into the coarse aggregate, forming the template and the trowel and other extrusion processes, to ensure that the cement concrete pavement density, especially the smoothness of the road has increased significantly, to meet the high-grade roads, airport flight zone and other projects of high standards of quality requirements.
            1.2 Paving the process fully automated, using electro-hydraulic control systems, sensors, steering and lift control, it set the fabric of cement concrete, paving, compacting, forming and trowel etc, to make a molding of cement concrete pavement. And can adapt to different widths (3.66 ~ 9.75m) and different thickness (maximum thickness of up to 48.3cm) of cement concrete pavement construction requirements for concrete paver speed based material speed.
            1.3 in the paving process, supplemented with artificial, can according to design requirements in the cement concrete pavement into the middle or side edge of reinforced dowel bar automatically.
            2 Scope
            Applicable to the cement concrete highway class, urban roads, airport flight zone, container yard and plaza floor works.
            3 Process principle
            Cement concrete pavement slippery principle of spreading machines process as shown below:
         
        Device through the spiral fabrics (including secondary fabric devices) Uniform fabrics, vibrator and vibrators tap, slide out by sliding the template shape, and finally by the trowel plate rubbing the surface of soft refurbishment.
            Construction Technology 4
        In the acceptance of primary or basic refurbishment after passing paving benchmark
