LANDSLIDE PREVENTING AND DRAINING PROCESS FOR SLANT SURFACE

摘要

PURPOSE:To effectively drain the water contained in a slant surface to the outside, to prevent the landslide liable to occur after rain, and to prevent the framework from being lifted by frost in winter. CONSTITUTION:Cheeses 14 provided with a receptacle portion 14a and an inset pipe portion 14b are connected to the upper surface of a water collection pipe 16 burried in a slant surface, and flat water guide plates 3-5 are radially fixed on both sides of the sheese 14 with ribs 10 and 11, with small gaps 6 and 8 therebetween. The groove portion 9a of a water collection plate 9 substantially y-shaped in cross section is fixed below the gaps 6 and 8 with ribs 12 and 13, with a small gap 8 between the top edge of the plate 9 and the lower surfaces of the plates 4 and 5. The main frame units 2 thus formed are connected together by fitting the groove portions 9a to water conduit holes 14d, and the units 2 are coupled together by auxiliary frame members 15 to form a framework, which is then covered with soil.
