The utility model discloses an outdoor anti freezing water pipe, which comprises a water pipe and a waterproof anti-corrosion layer, a heating layer and a heat preservation protective layer which are successively sleeved outside the water pipe. A temperature detection unit is arranged between the waterproof anti-corrosion layer and the heating layer, the temperature detection unit includes a thermometer and a display, the heating layer is an electric heating belt, the electric heating belt is evenly wound on the waterproof anti-corrosion layer, and the electric heating belt passes through The wire is connected to a power junction box. Through the thermometer and display, the utility model can intuitively understand the temperature of the stratum where the water delivery pipe and the water delivery pipe are located. When the stratum temperature is low, it can be considered that the electric heating belt is started to heat the water delivery pipe and the heat preservation protective layer wrapped on the water delivery pipe, so as to maintain the temperature of the water delivery pipe, the heat preservation protective layer and part of the soil above 0 \u2103, so as to ensure that the water delivery pipe is not frozen and the water delivery pipe is not frozen The internal water body can flow freely to maintain the normal operation of the whole waterway and meet the needs of production and life.
【技术实现步骤摘要】
一种室外防冻水管
本技术涉及寒冷地区的排水施工领域,尤其涉及一种室外防冻水管。
技术介绍
在我国东北和西北部分高寒地区,冬季气温低,极端温度可达-40度以下,对室外供水和排水管线造成冰冻灾害,影响供水管线正常运行。传统的的防冻措施是在施工时加深管沟开挖深度,将管沟开挖深度增加至极限冻土层,这样会增加开挖工程量和管道安装难度,同时不便于检查维护,一些特殊检查部位为便于检查需设置离地面较近,为了防止这些检查部位冻结需要刻意采取堆土和覆膜等措施进行防冻,而且如果在某一时段出现创历史记录的极寒天气,管道安装地层因极端低温变成冻土达到结冰条件,则整个管道系统将被冻结,使整个水管回路冻结瘫痪,丧失输水功能。
技术实现思路
本技术要解决的技术问题是克服现有技术的不足,提供一种在极端天气时人工控制开关实现水管加热,预防管道内水体冻结,确保供水排水管线回路正常运行的室外防冻水管。为解决上述技术问题,本技术采用以下技术方案:一种室外防冻水管,包括输水管和依次套于输水管外的防水防腐层、加热层和保温防护层,所述防水防腐层与加热层之间设有温度检测单元,所述温度检测单元包括温度计和显示器,所述加热层为电加热带,所述电加热带均匀的缠绕在防水防腐层上,所述电加热带通过导线连接一电源接线盒。作为上述技术方案的进一步改进,所述防水防腐层为阻水胶带,所述阻水胶带均匀密实的缠绕在输水管上。作为上述技术方案的进一步改进,所述保温防护层为聚酯乙烯层或发泡氯乙烯层。作为上述技术方案的进一步改进,所述输水管为 ...
