摘要
在区域集中供水向山区延伸背景下,钢丝网骨架塑料复合管因性能优良被广泛应用,但山区高差大、场地狭小、温度波动显著等特点,导致传统熔焊工艺存在接口质量不稳定、效率低等问题。文章结合工程实践,提出优化技术:用手持旋转刮刀均匀去氧化层,可调节木制托架校准同轴度,建立三段式温度分段熔接机制,形成“小、灵、快、省”方案。该技术实现了管道接口零渗漏,显著缩短了施工周期,有效降低了综合成本,为山区复杂环境管道熔接提供了高效解决方案。
With the extension of regional centralized water supply systems into mountainous areas,steel mesh reinforced plastic composite pipes have been widely adopted due to their excellent performance.However,the large elevation differences,narrow working spaces,and significant temperature fluctuations in mountainous terrains lead to problems in traditional fusion welding processes,such as unstable joint quality and low efficiency.Based on engineering practice,this paper proposes several optimized techniques:using a handheld rotary scraper to evenly remove the oxide layer,employing adjustable wooden brackets to ensure coaxial alignment,and establishing a three-stage temperature-controlled fusion mechanism.Together,these measures form a“small,flexible,fast,and cost-effective”solution.The proposed method achieved zero leakage at pipe joints,significantly reduced construction periods,and effectively lowered overall costs,thereby providing an efficient solution for pipeline welding in complex mountainous environments.
