style="font-family:Microsoft YaHei;font-size:14px;"> </span><br /> <span style="font-family:Microsoft YaHei;font-size:14px;"> 當采用土工布作反濾層時，應先在底部及兩側鋪好，并預留頂部覆蓋所需的土工布，拉直平順緊貼下墊層，所有縱向或橫向的搭接縫應交替錯開，搭接長度均不得小于30厘米。</span><br /> <span style="font-family:Microsoft YaHei;font-size:14px;"> 盲溝的埋置深度，應滿足滲水材料的頂部（封閉層以下）不得低于原有地下水位的要求。當排除層間水時，盲溝底部應埋于最下面的不透水層上。在冰凍地區，盲溝埋深不得小于當地最小凍結深度</span><br /> <span style="font-family:Microsoft YaHei;font-size:14px;"> </span><span style="font-family:Microsoft YaHei;font-size:14px;">除盲溝之外，其他形式的滲溝施工方法應嚴格按《公路路基施工技術規范》，<strong><u><a href="http://www.370255.com" target="_blank">盲溝</a></u></strong>只宜用于滲流不長的地段，且縱坡不應小于1%,出水口底面標高，應高出溝外最高水位0.2M。</span> </p> <p>
