class="cpxq_txt">近十几年，随着大量的塑料管在排水行业得以运用，如u-pvc(聚氯乙烯)管、pe(聚乙烯)管和hdpe(高密度聚乙烯)管等塑料管虽然有耐酸碱抗腐蚀、安装运输方便和综合造价低的优势，但塑料管存在易发生变形和破裂等结构性缺陷，一旦管道发生变形和坍塌，则需要花费很大的代价处理塌陷部分，尤其是中小型塑料排水管，而目前现有的短管置换法、裂管法都采用静压裂管技术硬挤强拉的方式，未能切割破碎原管材并清理出管道，易造成钻头卡死，管道标高控制不准。<br /> 可见，现有技术中的通过施工弊端挤强拉的方式实现对旧管的替换的替换效果差，且现有技术中缺少能实现旧管的破碎和新管的替换同时进行的置换技术，存在无法对坍塌受损的旧管进行置换。本公司提供了一种管道置换系统及方法，以解决现有技术中存在无法对坍塌受损的旧管进行置换的问题。<br /> 管道置换系统，包括钻杆、环切钻头组件和顶进装置，所述钻杆的外径小于旧管，所述钻杆穿过旧管的一端，所述环切钻头组件的一端连接于所述钻杆的穿过旧管的一端，所述环切钻头组件的另一端与新管的一部可拆卸连接，所述环切钻头组件的用于连接新管的端部与新管之间可发生相对转动，所述顶进装置的端部与新管的另一部可拆卸连接，所述顶进装置的用于连接新管的端部与新管之间可发生相对转动，所述环切钻头组件的外径大于或等于旧管外径，所述钻杆通过拉动所述环切钻头组件朝旧管的另一端移动以使所述环切钻头组件对旧管进行破碎，所述顶进装置通过推动新管朝向所述环切钻头组件移动以带动新管占据旧管移动前的位置。<br /> 管道置换可以满足不开挖地面，井内操作直接更换新型PE材质各种管径管材，替换原有破损及塌陷部分。此操作工艺实施后达到正常排水需求，有用时少，成本低的特点。<br /> <br /></div> </div> </div> </div> </div> </div> </main>  <footer> <div class="footer"> <div class="container">
