18、属设备进行巡回检查，及时做好维护和保养工作，提高工作效率。（4）当孔钻到要求深度后，应对孔反复进行通孔，为下换热管创造顺利条件。4、试压下换热管之前应按设计要求进行水压试验。试验压力为2.5MPa，稳压至少 30min,稳压后压力降不应大于3%，且无泄漏现象。将其管口热熔密封，准备下管。5、下换热管（1）为保证换热效果，防止支管间发生热回流现象，两根换热支管之间应保持距离，下管前应采用分离定位管卡将两根换热管进行分离定位，分离定位管卡的间距为3 米。文档编码:CG8C5N2B6X5 HT4Q4X6V6V6 ZH6B5B8U3P7文档编码:CG8C5N2B6X5 HT4Q4X6V6V6 ZH6B

25、5B8U3P7文档编码:CG8C5N2B6X5 HT4Q4X6V6V6 ZH6B5B8U3P75（2）根据井的实际情况，下管应采用下管机下管，下管速度要均匀，防止下管过程中损坏管道，如果遇有障碍和不顺畅现象，应及时查明原因，待做好处理后才能继续下管。（3）下管机下管时应将HDPE 管头与下管器连接固定，在将塑料绳捆绑在管头上。（4）应将下管器连同 HDPE 管插入井孔，一旁用人工将 HDPE 管抬起，进行下管。（5）应从管头没入钻孔时根据钻杆测量，至有效深度后停止下管，并用尼龙绳牵引防止下沉。（6）如果采用下管机下管，换热管道到位后，应提起下管钻杆，提杆过程中为防止换热器上浮，在提杆前应少许灌

26、浆或灌入少量黄沙。6、回填（1）回填方式：应采用从地下返浆回填的方法灌回填料。采用专用回填泵，由孔底部位注入填料向上反填，逐步排除空气，确保无回填空隙，保证了传热效果。（2）回填料：回填材料的导热能力对地下管路的换热能力有着重要的影响，回填料在施工完成后与地下换热器接触最紧密，回填料的配比与选择，决定了其传热性能，传热特性直接影响换热效果。除考虑传热外，还要考虑其凝固强度等级，因地质结构不同、膨胀能力不同，产生的挤压力也差别很大。选择合适的回填料还可以防止挤压破坏地下换热管。因此，依据地质报告，配比选择回填料，也是保证地热泵成功应用的重要一环。文档编码:CG8C5N2B6X5 HT4Q4X6V
