Title:
SLOPE GROUND DRAINAGE STRUCTURE AND METHOD FOR CONSTRUCTING SAME
Document Type and Number:
WIPO Patent Application WO/2013/133179
Kind Code:
A1
Abstract:
On a slope (1), a midrib drainage (2) is installed in a vertical direction of the slope. A lateral vein pipe (3), part of which is exposed from the ground surface, is connected to the midrib drainage in a descending slope from a horizontal direction of the slope. A water collection pipe (4) that has a water collecting hole (4a) is inserted into the ground, and an end portion is connected to the lateral vein pipe. A surface water collection port (8a) that is capable of collecting water flowing down from an upper side of the slope is installed in the lateral vein pipe. Rainwater flows from the surface water collection port of the lateral vein pipe into the lateral vein pipe. Osmosis water inside the ground flows through the water collection pipe into the lateral vein pipe. Both the surface water and the osmosis water are excluded from the slope ground after flowing into the midrib drainage and flowing downward, and can be excluded effectively. Drainage of the osmosis water is performed by the midrib drainage and lateral vein pipe which is common to surface water collection means. Therefore, efficiency can be high and manufacturing costs can be reduced.
