摘要
水平定向钻(HDD)指采用水平定向钻机成孔并敷设管道的一种管道施工方法。进行热力管网设计及施工时,会经常遇到需要下穿河道、公路以及沟渠物等情况无法正常开挖施,宜采用水平定向钻施工。基于此,对热力管网水平定向钻设计及施工重点进行探究。
Horizontal directional drilling(HDD),refers to a pipeline construction method using horizontal directional drilling rig to form holes and lay pipelines. In the design and construction of heating pipe,it is often encountered that it is necessary to go through rivers,roads and ditches and other conditions that cannot be excavated normally. Based on this,the paper discusses the key points of horizontal directional drilling design and construction of heating pipe.
