Abstract
Hydraulic filling methods are widely applied to suppress the land subsidence recently. But the research on high-efficiency hydraulic filling to protect the land subsidence is rare. In this study, field experiments to improve the efficiency of the hydraulic filling method are performed by changing the property, specification of the filling material and injection pipe. The filling amounts using vertical injection pipe, reducing tee (${\phi}100mm$) pipe, reducing tee (${\phi}80mm$) pipe and reducing tee (${\phi}50mm$) pipe showed 28.84 ton, 42.62 ton, 53.33 ton, and 63.33 ton respectively. The filling rates using reducing tee (${\phi}100mm$) pipe, reducing tee (${\phi}80mm$) pipe and reducing tee (${\phi}50mm$) pipe showed 47.8%, 84.9% and 119.6% respectively. Filling efficiency can be incresed by using reducing tee. This study shows that simply changing the type of injection pipe is expected to increase the hydraulic filling rate.
