Pipe Reinforced Drainage (PDR) Method.

Landslides are a natural disaster that can cause serious damage to people and the environment.

- At the landslide and erosion locations of the positive slope: the cause is due to prolonged rain with large surface water flow, the construction area has underground water, the geology of the area is mainly strongly weathered basalt rock which is very susceptible to erosion, the geological and hydrological terrain conditions are complex and have not been fully discovered by the survey, the system of top ditches and longitudinal ditches reinforcing the slope is not complete, water runs directly on the surface of the excavated foundation slope leading to erosion.
