Application and design of wood stave pipelines

In the context of a research project studies for the application of wood stave pipelines as inlet pipe for hydroelectric power stations were performed. The wood stave pipelines shall be used in mattock caves in Java, Indonesia in order to use underground water resources for the local population (Fig. 1). The access to the caves is very cramped; therefore pipelines of steel or concrete can not be transported in the caves. By contrast single wood staves may be transported separately into the caves and put together to a pipeline in situ. Because of the low dead weight of the single wood staves and the adaptation to the cave gradient, wood is an adequate building material for pipelines in caves. Fig. 1: Mattock cave in Java, Indonesia
