施工概念

<p><span lang="ZH-TW"><b>施工项目：</b>路基土石方、涵洞、挡土墙、路肩、边坡、排水管线</span><span lang="EN-US"><o:p></o:p></span></p>
<p><span lang="ZH-TW"><b>施工流程：</b>交通导行一一技术安全交底（<b>项目技术负责人</b>依据施工方案向作业人员就工程难点、技术要点、安全措施交底）一测量放线</span><span lang="EN-US"><o:p></o:p></span></p>
<p><span lang="ZH-TW"><b>附属构筑物：</b>先地下后地上，先深后浅；管线拆改加固保护，修筑排水设施</span><span lang="EN-US"><o:p></o:p></span></p>
<p><span lang="ZH-TW"><b>路基土石方施工：</b>开挖路堑/填筑路基一整平路基一压实路基一修整路床一修剪防护工程</span><span lang="EN-US"><o:p></o:p></span></p>
施工技术
<span lang="ZH-TW">排除积水、清理树根杂草淤泥、处理坟坑井穴、分层填筑压实，湿土翻拌晾晒，干土加水，达到最佳含水量</span>
三种路基施工
<span lang="ZH-TW">挖土路基一一分层、严禁掏洞、管道边</span><span lang="EN-US">1</span><span><span lang="EN-US">m</span></span><span lang="ZH-TW">及缆线</span><span lang="EN-US">2</span><span><span lang="EN-US">m</span></span><span lang="ZH-TW">范围人工开挖、留压实量，雨水支管及检查井周围用石灰土或二灰砂砾填实</span>
<span lang="ZH-TW">填土路基一先找平、坡度陡于1:5修成台阶（高</span><span lang="EN-US">30</span><span><span lang="EN-US">cm</span></span><span lang="ZH-TW">宽</span><span lang="EN-US">1</span><span><span lang="EN-US">m</span></span><span lang="EN-US">)，</span><span lang="ZH-TW">分层填筑，下层合格上层填筑，填筑宽度比设计每侧宽</span><span lang="EN-US">50</span><span><span lang="EN-US">cm </span></span>
<span lang="ZH-TW">石方路基一先码砌边部后填筑中部，管线及构筑物四周土料回填基设整平层，采用未筛分碎石和石屑或低剂量水泥稳定粒料（厚 10</span><span lang="ZH-TW">〜</span><span lang="EN-US">15</span><span lang="EN-US">cm</span><span lang="EN-US">)</span>

<span lang="ZH-TW">路基压实：方式一重力压实（静压</span><span lang="EN-US">）</span><span lang="ZH-TW">和振动压实，原则一轻静低慢叠4,轮外缘与路基边保持安全距离小型夯击防止漏夯，夯击面积重叠 </span><span><span lang="ZH-TW">1/4</span></span><span><span lang="ZH-TW">〜</span></span><span><span lang="ZH-TW">1/3 </span></span>
特殊季节施工
<p><span lang="ZH-TW">雨期施工：避开、分段集中施工、罩棚、留横坡、截水沟、当天挖完、填完、压完、不留后患 </span></p>
<span lang="ZH-TW">冬季施工：避开、覆盖、挡风、加热、保温，挖到设计标高立即碾压（下班后刨送覆盖），高等路不得含有土块，次高级路面冻土快不得大于<br></span><span lang="EN-US">10</span><span lang="EN-US">cm</span><span lang="ZH-TW">且含量小于15%</span>
