随着我国能源战略的不断调整,长输管道作为最经济的运输方式,最近来在我国得到飞跃式发展,由于长输管道的空间跨越性大,而管道沿线各地的地质、水文、气候条件复杂多变,地震、地壳变动、山体滑坡、泥石流、山洪、河流湖泊及农田水网冲刷等均能导致管道裸露损坏,本文主要就长输管道穿越河流湖泊及农田水网时造成的水害现象进行分析,找出主要原因,探讨工程上常采用的水工保护措施,并因地制宜的加以采用,以达到最佳保护管道的目的。
With the continuous adjustment of China’s energy strategy, the long-distance pipeline, as the most economical mode of transport, has recently gained leaps and bounds in our country. Due to the large space span of long-distance pipelines and the complicated geological, hydrological and climatic conditions all over the pipeline Volatile, earthquakes, crustal changes, landslides, debris flow, flash floods, rivers and lakes and farmland water scouring can all lead to pipeline damage. This paper mainly analyzes the water damage caused by the long-distance pipeline crossing rivers, lakes and farmland water networks , Find out the main reason, discuss the hydraulic protection measures often used in engineering, and adopt it according to local conditions in order to achieve the best protection of the pipeline.
