摘要
为了对甘肃省科学院15.3 hm2绿化基地实施水利配套,安装108 m3成品玻璃钢蓄水池一座,并敷设管道设施进行喷灌配套。从两山后五泉供水管道接水,沿皋兰山北坡公路敷设DN100镀锌钢管道至绿化基地上方,再垂直山坡布设输水管道至玻璃钢蓄水池。灌溉系统全部采用固定式,通过管道利用自然水头自压喷灌。通过对工程场地的地形地貌、地质构造和管床工程地质条件等岩土性质参数的前期勘察,为蓄水池的建设提供了基础设计依据。根据工程规划,设计确定了灌溉制度、喷洒组合方式和轮灌方案,对比选择了配水管道的管材,计算得出了附属建筑物的建设方案。该工程不仅解决了甘肃省科学院绿化基地的灌溉问题,也为兰州市生态环境的建设起到推进作用。
In order to implement water conservancy facilities supporting in the 15.3 hm2 greening base of Gansu Academy of Sciences,a 108 m3 finished glass fiber reinforced plastics reservoir was installed,and the pipeline facilities were laid for sprinkling irrigation.From the water supply system of the Five Springs Mountain behind The South and the North mountains,DN100 galvanized steel pipes were placed along the Gaolan mountain highway north slope to the top of the greening base.Then water supply pipeline vertical to the slope was set up to the glass fiber reinforced plastics reservoir.All irrigation systems are fixed,using natural water head to spray through the pipelines.The preliminary investigation of the topographical and geomorphic features,geological structure and geological conditions of the pipe bed provide basis for the construction of the reservoir.According to the project plan,the irrigation system,spraying combination method and rotation irrigation scheme are designed and determined.The pipes of water distribution are selected and the construction scheme of ancillary buildings is calculated.The project not only solved the irrigation problem of the greening base of Gansu Academy of Sciences,but also promoted the construction of the ecological environment of Lanzhou city.
