Research on the construction technology of tunnel-type underground reservoir in island areas

Abstract

The water consumption structure and water demand of remote islands with homestay tourism as the main industries were calculated and analysed. The result showed that there were obvious seasonal differences in the water demand of such islands. Based on the temporal and spatial characteristics of island water resources, it is recommended to build tunnel-type groundwater reservoir, to form the optimal allocation mode of water resources in the surface and underground, dry and rainy seasons and different geographical space. The construction process and technical points of tunnel-type underground reservoir were proposed, which was starting from the whole process including site selection, source determination, clean-up and disinfection, local impermeable, dam-blocking construction, ancillary facilities construction, water level and water quality monitoring and subsequent water purification.
