根1976年6月“Facts about Danish District Heating”报导,丹麦奥尔湖斯区域供热厂与其它机构合作,研制出一种施工速度快、造价相当于普通混凝土热力管沟的新工艺,克服了原来用瓦接法制作管沟接头多和接缝不严的缺点,解决了沟邦与沟底分别施工时要破坏其结构强度的毛病以及因设
In June 1976, “Facts about Danish District Heating” reported that the Danish Al Husse district heating plant cooperated with other institutions to develop a new process with a fast construction speed and a cost equivalent to that of ordinary concrete thermal pipe trenches. The original method used tile joint method to make pipe joints with many joints and lax joints, which solved the problems of destroying the structural strength of the ditch and ditch when they were separately constructed and their design.
