Description
技术领域technical field
本实用新型涉及预制保温管技术领域，具体为一种防止冷桥热损失的预制直埋保温管。The utility model relates to the technical field of prefabricated thermal insulation pipes, in particular to a prefabricated direct-buried thermal insulation pipe for preventing cold bridge heat loss.
背景技术Background technique
预制直埋保温管道较之架空和地沟敷没具有不占地、不影响城市观瞻、热损失小、防水、防腐性能好、节约投资、缩短施工周期、维修费用低等诸多优点。而目前使用的预制直埋管由钢管、防腐层、支架、保护层五部分组成，是整体式的保温管道，在供热过程中因钢管内热水或蒸汽的温度很高，钢管必然受热膨胀，而钢管、保温层、支架三种物质的膨胀系数不同，这三者之间将无法同步位移，必将导致保温层、钢管、支架之间产生一定的开裂现象，即保温层与钢管之间、保温层与支架之间、支架与钢管之间产生一定的间隙，这种间隙用肉眼可能观察不到，但通过间隙中的气体热传导而造成的热能损失却不可估量。Compared with overhead and trench laying, prefabricated direct-buried thermal insulation pipelines have many advantages such as not occupying land, not affecting city views, small heat loss, waterproof, good anti-corrosion performance, saving investment, shortening construction period, and low maintenance costs. At present, the prefabricated direct-buried pipe is composed of five parts: steel pipe, anti-corrosion layer, bracket, and protective layer. It is an integral heat preservation pipe. During the heating process, due to the high temperature of hot water or steam in the steel pipe, the steel pipe will inevitably expand due to heat. , but the expansion coefficients of the steel pipe, the insulation layer, and the bracket are different, and the three materials will not be able to move synchronously, which will inevitably lead to a certain cracking phenomenon between the insulation layer, the steel pipe, and the bracket, that is, between the insulation layer and the steel pipe. 1. There is a certain gap between the insulation layer and the bracket, and between the bracket and the steel pipe. This gap may not be observed with the naked eye, but the heat loss caused by the heat conduction of the gas in the gap is immeasurable.
