最近中瑞環?？萍脊こ坦局袠斯谚F路，當前東北地區進入高寒環境，那么如何確保<strong><u><a href="http://www.majubuanatravel.com" target="_blank">隧道防水板</a></u></strong>在高寒環境中鋪設質量，中瑞環保根據多年高寒環境施工經驗提供一下幾點建議：</span> </p> <p style="text-align:center;"> <span style="font-family:'Microsoft YaHei';font-size:18px;"> <img onload="resize(this,700)" src="/upload/image/20161115/20161115130850_14180.png" alt="" /></span> </p> <span style="font-family:'Microsoft YaHei';font-size:18px;"> （1）首先保證隧道防水板的質量，必須嚴格按著鐵路2008科技級的標準生產，一定保證隧道防水板的質量。 </span><br /> <span style="font-family:'Microsoft YaHei';font-size:18px;"> （2）隧道防水板鋪設前，噴混凝土表面處的鋼筋頭和錨桿頭先切除，再用手持砂輪機磨平，對凹凸不平部位應修鑿噴補，使混凝土表面平順，有局部滲水處，應進行處理。</span><br /> <span style="font-family:'Microsoft YaHei';font-size:18px;"> （3）隧道防水板按環向鋪設，焊接工序與固定工序應緊密配合，一般先焊接，后固定。</span><br /> <span style="font-family:'Microsoft YaHei';font-size:18px;"> （4）隧道防水板鋪設的搭接寬度為10厘米，焊接寬不小于2厘米，漏焊、假焊處應補焊，若有烤焦、焊穿處，應用同樣的防水板焊貼覆蓋或按監理工程師指示辦理。</span><br /> <span style="font-family:'Microsoft YaHei';font-size:18px;"> （5）固定隧道防水板采用膠熱焊接，膠墊與膠墊之間防水層不得繃緊，要保證板面與噴射混凝土密貼。</span><br /> <span style="font-family:'Microsoft YaHei';font-size:18px;">

<span style="font-family:'Microsoft YaHei';font-size:18px;"> （1）首先保證隧道防水板的質量，必須嚴格按著鐵路2008科技級的標準生產，一定保證隧道防水板的質量。 </span><br /> <span style="font-family:'Microsoft YaHei';font-size:18px;"> （2）隧道防水板鋪設前，噴混凝土表面處的鋼筋頭和錨桿頭先切除，再用手持砂輪機磨平，對凹凸不平部位應修鑿噴補，使混凝土表面平順，有局部滲水處，應進行處理。</span><br /> <span style="font-family:'Microsoft YaHei';font-size:18px;"> （3）隧道防水板按環向鋪設，焊接工序與固定工序應緊密配合，一般先焊接，后固定。</span><br
