In this case, both end parts 12, 13 of the elastic sheet part 11 are overlapped to each other via a double-sided adhesive tape part 10, and an excessive part 20 in the double- sided adhesive tape 10 is stuck to the double-sided adhesive taper part 10 in front of the other end part 13. An armor cover 5 is wound around so that its standing piece 16 and its bent piece 17 are directed outward and the base parts of the both pieces 16, 17 are matched with the pressing plate. In addition, the standing piece 16 and the bent piece 17 are fastened by means of a bolt 16 and a nut 19 serving as fastening means, and consequently, a joint structure 1 for both corrugated double layers 2, 3 is constructed.

摘要： PURPOSE:To facilitate the conveyance of drain material for soil improvement by connecting a plurality of openings to the approximately central part between rid plates of both upper and lower plates in the direction of extrusion in succession and, at the same time, rolling and surrounding the outsides of both upper and lower plates by a filter material in a state of non-adhesion. CONSTITUTION:In a drain material consisting of a plurality of a pair of upper and lower plates 11a and 11b having opposite broad surfaces and a plurality of rib plates 11C formed together with the upper and lower plates 11a and 11b as a unit and arranged at approximate right angles to the plates 11a and 11b, openings 11d with a diameter almost equal to the distance between the rib plates are formed in plates among the rib plates 11C arranged in parallel at specific intervals in a row in the direction of extrusion. Opening rows are non-symmetrically arranged each other in the both upper and lower plates 11a and 11b, and a longer molding 11 is easily rolled and is conveniently conveyed. After that, the outsides of both upper and lower plates 11a and 11b are rolled and surrounded by a filter material in a state of non-adhesion, and when the longer molding is rolled and is conveyed, the rolling resistance is decreased and is not bulky.
