Abstract
PURPOSE: To heighten the effect of drainage by opening a vertical shaft leading to a culvert on the surface of the ground, forming a water-collecting ditch around the opening of the vertical shaft on the ground surface and thereby letting the rainwater and the like on the ground surface flow from the water-collecting ditch through the vertical shaft into the curlvert.
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 under a blade body in the ground. At the back of the above device a tiller 29 and a grooving tool 36 are arranged. By the rotation of the tiller 29 shallow ditches 37 are formed on the right and left sides of the vertical shaft 4, and further, the guide part 36a of the grooving tool 36 getting in the vetical shaft 4, a horizontal part 36c touches slidably the surface of the ditches 37, while the ditch-opening part 36b scrapes off the ground around the opening of the vertical shaft 4, thus forming a V-shaped ditch 38. Thus, through a water-collecting ditch formed around the opening of the ditch 4 on the ground surface, the rainwater and the like on the surface of the ground are to be let easily to flow into the culvert 3, thereby the effect of drainage being heightened.
