CONSTITUTION: The incline drainage structure comprises an upper plate(10) provided with latticed ribs(12) formed in an outer frame(11) and a drainage net(13) formed in each latticed rib(12), and projections(22) formed on both sides to make a plate-shaped body form a drainage passage(21), wherein stopping nails(14) and a bearing pin are projected on the upper and lower sides of the upper plate(10), a stopping nail is projected on the lower side of the lower plate(20), a fitting projection(24) and a fitting joint are formed on the front and rear of the lower plate(20), and fastening holes(16,26) are formed on both sides of the bodies of the upper plate(10) and the lower plate(20) to fix the upper, lower plates(10,20) and to connect with an adjacent drainage structure.
