PURPOSE:To prevent collapse of a slope, by a method wherein a tubular object, in which pores are formed over the overall length is inserted into soil slope, and underground contained in a soil slope is caused to flow through the pores into the tubular object. CONSTITUTION:Plural tubular objects 1, in which pores 4 are formed throughout the overall length, are inserted in a soil slope 2, and a portion 5, exposed from a ground surface of each tubular object 1 is connected to a drain pipe 6. Water in the underground of the soil slope 2 is guided into the tubular object 1 through the pores 4, and is drained through the drain pipes 6 to a side groove 7. This causes an underground water level in the soil slope 2 to be lowered and prevents collapse of the soil slope 2. |
