Study on Reasonable Installation of Sewers in Steep Gradient
Abstract:The percentage of the Japanese population served with sewers reached 73.7% as of the end of FY2009. Sites of sewer construction are gradually moving from flat areas to mountain areas. For this reason, together with recent economic circumstances, high cost performance in sewer construction are being requested. Mountain areas comprise distinctive topography including steep gradients and areas of repeated S-curved road. As such, it is expected that using conventional sewer design practices would increase economic burdens concerning construction thereof and construction periods due to requirements such as increased depth of buried main sewer lines and number of manholes. This study examines pipe installation methods under such field conditions, aiming to reduce installation costs by taking the latest technological trends into consideration.
