Abstract
Recently, as buildings have become taller, base structures on construction sites have to be excavated[中村 1] wider and deeper. Generally, excavated soil is transported vertically using clamshells. However, clamshells are large construction machines, and their operation is subject to physical and time limitations. In this study, we focused on the intestinal tract. We used a peristaltic conveyance system that simulates a peristaltic movement pump to vertically transfer excavated soil. In a previous study, we successfully lifted low-water content sediments using a watering system that increases the water content ratio of the transported sediment. From the experiments, the lifting conditions were determined according to the type of sediment. However, the relationship between the driving conditions of the device and vertical transport is not known. For practical use, the rate of lifted soil should show an improvement. In this study, we investigated the driving conditions. The lifting rate was compared for various patterns under different conditions.
