Abstract
PURPOSE: To heighten the effect of drainage by opening a vertical shaft leading to a culvert on the surface of the ground, providing, by cutting, drainage-guiding ditches on both sides of the opening of the vertical shaft on the surface of the ground and thereby draining off the water on the ground surfade into the culvert through the drainage-guiding ditches.
CONSTITUTION: The vertical shaft 4 and the culvert 3 are formed in the ground by advancing a device fitted with a projectile-shaped ditch-digging body 2 under a blade body 13 in the ground. At the back of the above device a gauge wheel 18 is arranged. On the surface of the outer periphery of this gauge wheel 18 many ditch- digging blades 18b are provided, by cutting, in such a manner that, when the gauge wheel 18 is rolled, the guide projection 18a of the wheel 18 being put in the vertical shaft 4, the surrounding ground of the opening of the ditch 4 is pressed and guide ditches for drainage are cut on both right and left sides of the opening. Thus, through these drainage-guiding ditches formed on both sides of the opening of the verticla shaft 4, the rainwater and the like on the surface of the ground are let to flow through the ditch 4 into the culvert 3, thereby the effect of drinage being heightened.
