长输成品油管道沙区护坡保护实践
Attempts to Protect the Bank Protection for Products Pipeline in Desert Area
-
摘要: 由于青藏公路二次改建, 格拉管道沿线的植被被破坏而导致沙化, 这给管道的保护带来了困难。通过沙化区管道护坡保护工作多年来的实践, 总结出三点经验: 第一, 原地取沙掩埋构筑护坡不能承受狂风袭击和洪水冲刷; 第二, 草袋或编织袋装沙垒护坡寿命较短; 第三, 采用毛石浆砌护坡并适当预留泄洪洞, 既抵御了狂风的袭击, 又免除了洪水的冲刷, 使长输管道得到了有效的保护, 消除了事故隐患。Abstract: Due to the secondary reconstruction of the Qinghai-Tibet Highway, the vegetation along Golmud-Lhasa Products Pipeline was destroyed and the covering earth began to desertify, making the pipeline protection more difficult. Based on the practices on bank protection for pipelines in desert, the following statements are given: ① Bank protection built by using local sandy soil can withstand neither windstorms nor floods; ② Bank protection built with straw bags or cloth bags suffers from short service life; ③ The bank protection built with rubble concrete and provided with sluiceways can survive from windstorms and floods, offer effective pipeline protection and remove the hidden perils.
