外文翻譯---淺談水泥混凝土路面縱向裂縫的防治(存儲(chǔ)版)
【正文】 ad bed is located directly on the natural soil。 Vertical cracks in cement concrete pavement may be the deal with all of local processing and handling methods. Before processing, the cracks must be generated to investigate the cause analysis, to determine what causes and then determine what approach to use. All processing This approach is to crack the concrete slab has been cleared of all to retain the horizontal connecting bars. If there is damage to the grassroots level appropriate to deal with, and then repoured with the original surface of the concrete slab, such as strength. If that is the basis of cracking due to the road surface caused by cracking, it should be in the new fullcast concrete slab added to a wide range of singlelayer or doublereinforced, reinforced the general specifications of the steel used Φ10 made to 20 * 20cm spacing . This method is suitable for a variety of reasons arising from the road surface cracking. The use of this approach, the cost of the larger. Partial treatment Local processing is in the cracks on both sides of the range of not less than 50cm cutting a groove, deep groove thickness of ~ times the slot on both sides must be neat, should be cut cutting machine. Clean bottom, laying in the bottom Φ10mm reinforced with banding of 10 * 10cm steel net, and then poured with the same intensity of the original concrete pavement pebbles concrete, moisture transport and opening up health after 28 days. This method is relatively simple to deal with the economy, but only applies to the road as a result of their own strength and have a crack.。Cement Concrete Pavement On The Prevention Of Vertical Cracks 1 Preface Cement concrete pavement cracks a variety of forms. There is prima facie net crack, horizontal cracks, vertical cracks and so on. Life on the road most affected among the longitudinal cracks. Such cracks are usually the central line of the lane, in the event that a few or dozens of pieces of concrete slab for cracking, and cracks throughout the thickness。這種處理方法是將已開裂的混凝土板全部清除，保留橫向連接鋼筋。，保證混凝土質(zhì)量加強(qiáng)施工管理是確?；炷临|(zhì)量的重要途徑之一。(2)零填及挖方路段在零填及挖方路段的基礎(chǔ)處理時(shí)，如果路槽范圍及路槽以下是普通土或松土?xí)r，處理深度不應(yīng)僅限于上路槽，對(duì)于下路槽（路槽頂面以下30~80cm范圍）也必須處理，其壓實(shí)度應(yīng)與上路槽相同。眾所周知，混凝土的密實(shí)程度 直接影響其強(qiáng)度。一是原材料質(zhì)量不合格。(3)零填及挖方路基這類路基如果出現(xiàn)縱向開裂 主要是基礎(chǔ)處理不當(dāng)或不徹底，基礎(chǔ)強(qiáng)度達(dá)不到應(yīng)有的承開能力。路床承受著路面所產(chǎn)生的恒載,同時(shí)還承受著由路面?zhèn)鱽淼男熊嚭奢d。淺談水泥混凝土路面縱向裂縫的防治1前言水泥混凝土路面的裂縫形式是多種多樣的。路面的基礎(chǔ)是路床。尤其是挖 方側(cè)是硬土或是巖石，出現(xiàn)縱向裂縫的機(jī)率更大。(1)混凝土強(qiáng)度達(dá)不到設(shè)計(jì)要求導(dǎo)致混凝土自身的強(qiáng)度不足有兩個(gè)方面的因素。這樣，水泥混凝土板就不可能過到均勻密實(shí)。另外在路基填筑時(shí)必須全幅填筑，不應(yīng)分幅施工，人為地造成縱向工作縫而形成薄弱面。所以攤鋪的混凝土板均勻、密實(shí)，無薄弱點(diǎn)或薄弱面。在處理之前，必須對(duì)裂縫產(chǎn)生的原因進(jìn)行調(diào)查分析，確定是什么原因引起的，然后再確定用什么方法處理。這種處理方法比較簡(jiǎn)單經(jīng)濟(jì)，但僅
