1、传统砖砌暖沟岩棉保温的施工工艺:挖沟 2×2 ( m ) 打混凝土垫层 → 埋设暖气管 角钢支架 → 钢管除锈 → 刷漆防腐 → 加工固定 卡 → 钢管焊接 → 钢管固定 → 水压实验 → 岩棉保 温 → 缠玻璃布 → 刷沥青漆 → 盖沟盖板 → 回填土。
1. The traditional construction technology of rock wool insulation in brick warm trench is as follows: digging trench 2 x 2 (m) to lay concrete cushion, burying angle steel bracket of heating pipe, removing rust of steel pipe, painting and anticorrosion, processing and fixing clamp, welding of steel pipe, fixing of steel pipe, water pressure test, rock wool insulation, wrapping glass cloth, brushing asphalt paint, covering plate of trench, backfilling soil.
其中还有挖沟取土的运输与倾卸置放,砂 石 、 水泥 、 砖块 、 角钢 、 岩棉 、 沟盖板等的采购和 运输 。 施工触及面大,中间环节多;占领施工场 地大,施工工期长,而且岩棉在施工和运输过程 中损耗率达10%以上 。由于岩棉纤维对人体皮 肤和呼吸道有激烈的刺激性,必需采取必要的劳动维护措施 。
Among them are the transportation and dumping of digging trenches for soil, the purchase and transportation of sand, cement, bricks, angle steel, rock wool, trench cover, etc. The construction touches a large area with many intermediate links, occupies a large construction site and has a long construction period, and the loss rate of rock wool in the construction and transportation process is more than 10%. Because rock wool fibers have intense irritation to human skin and respiratory tract, it is necessary to take necessary labor maintenance measures.
2、聚氨酯直埋保温管的施工工艺:钢管试压 → 除锈 → 硬质聚氨酯直埋管制造(以上工作在工厂停止) → 现场挖沟 → 直埋管焊 接 → 水压实验 → 现场发泡 → 回填土。
2. Construction technology of polyurethane direct buried insulation pipe: steel tube pressure test rust removal rigid polyurethane direct buried pipe manufacturing (above work stopped in the factory) digging trench welding of direct buried pipe water pressure test foaming backfill soil.
直埋供热管道保温不需求砌筑庞大的地沟,只需将保温管埋人公开,因而大大减少了工程占地,减少土方开挖量约50%以上,减少土建砌筑和混凝土量90%。同时,保温管加工和现场挖沟平行停止,只需现场接头,能够缩短工期约50%以上。
Directly buried heat-supply pipelines do not need to build huge trenches for thermal insulation. They need only be buried in public, which greatly reduces the construction area, reduces the amount of earthwork excavation by more than 50%, and reduces the amount of civil masonry and concrete by 90%. At the same time, the processing of insulating pipes and digging ditches on site are stopped in parallel, and the construction period can be shortened by more than 50% with only on-site joints.

比其他过去常用的管道保温资料低得多,保温效果进步4~9倍。再有其吸水率很低,加上保温层和外面防水性能好的高密度聚乙烯或玻璃钢维护壳,改动了传统地沟敷设供热管道"穿湿棉袄"的情况,大大减少了供热管道的整体热损耗,热网热损失为2%,小于国际10%的规范请求。
Compared with other commonly used pipeline heat preservation data, the heat preservation effect is improved by 4 to 9 times. With its low water absorption, high density polyethylene (HDPE) or fiberglass reinforced plastics (FRP) maintenance shell with good insulation layer and external waterproof performance, the situation of traditional trench laying heating pipeline "wearing wet cotton jacket" has been changed, and the overall heat loss of heating pipeline has been greatly reduced. The heat loss of heating network is 2%, which is less than 10% of the international standard requirements.
聚氨酯直埋保温管的制造和施工完整能够平行停止,能够在施工现场挖沟是在厂家消费,运输到后直接停止焊接。大大缩短了施工时间。
The manufacture and construction of polyurethane direct-buried insulating pipe can stop in parallel, and digging ditches in the construction site is consumed by the manufacturer, and welding can stop directly after transportation. The construction time is greatly shortened.
这种办法在缩短施工时间的同时,还省去大量的人力物力,而且聚氨酯直埋保温管由于其外抗腐蚀层的良好特性,在运输中过程中根本没有损失。所以聚氨酯直埋管在管道运输行业遭到了人们的欢送。
This method not only shortens the construction time, but also saves a lot of manpower and material resources. Moreover, the polyurethane direct-buried insulation pipe has no loss in transportation because of its good external corrosion resistance. Therefore, polyurethane direct buried pipe in the pipeline transport industry has been welcomed by people.
总之,高温预制直埋保温管不只具有传统地沟和架空敷设管道难以比较的先进技术、适用性能,而且还具有显著的社会效益和经济效益,也是供热节能的有力措施。
In a word, the high temperature prefabricated directly buried insulation pipe not only has the advanced technology and applicability which is difficult to compare with the traditional trench and overhead pipeline laying, but also has remarkable social and economic benefits, and is also a powerful measure of heating and energy saving.
