| PURPOSE: To prevent a collapse of an overall shape of a formed net by providing notches of the same number in a structure that coincides with the notches of a fixed die at a mold attaching unit for forming the net. CONSTITUTION: A plurality of peripheral notches 4 each having a substantially rectangular section for forming the net are formed at fixed die elements 1. A layer G of the net, at the time of being formed between the elements 1, is passed over a die attaching unit 5. A plurality of notches 7 coincident in number, shape and dispositions to those of the notches 4 of the elements 1 are formed on a surface 6 of the unit 5 for passing the layer G. The notches 7 have a function of supporting and guiding the state coincident in the shape to longitudinal strands of the net to prevent deformation and collapse of the net. The net having a large width and thickness can be formed. COPYRIGHT: (C)1990,JPO | ||||||

| PURPOSE:To exactly fix a filter to the inside of a water hole by a method in which a fitting portion directed toward the passing direction of water is erectly provided near one end portion of a plate filter with plural filter holes in an annular form. CONSTITUTION:In a drain filter 1 consisting of a synthetic resin plate filter 2 and a cylindrical fitting part 3, many filter holes 4 are formed in the whole face of the filter 2, a rib 5 is formed on the periphery of the filter 2, and paired coupling springs 8 are formed at the center of both sides. The filter 1 is attached to a water hole 9 by fitting the filter 2 into the water collecting portion 10 of the U-shaped groove block and also by fitting the fitting part 3 into the water conveyance portion 11. Since the portion 3 is pressingly coupled with the inner surface of the water conveyance portion 11 and the coupling spring 8 is pressingly coupled with the inner surface of the water collecting portion 10, the filter 1 can be strongly fixed to the inner surface of the water hole 9. | ||||||

| PURPOSE:To simplify mounting of a filter, by a method wherein a skirt-shaped firm adhering part is formed in a protruding manner to the outer preiphery of a cover part having a number of filter holes provided therein, and the firm adhering part is cut from the skirt side to form slits. CONSTITUTION:Before a drainage canal 1 is constructed, a cover part 6 of a filter 5 is inserted through a drainage hole 3 in a U-shaped ditch 2 from the outer surface side of a side wall 2a toward the interior of the U-shaped ditch 2 until the cover part 6 is positioned flush with the inner surface of the side wall 2a. This, when the drainage canal 1 is constructed, prevents earth flowing in the drainage hole 3 through a gravel layer 4 together with the water, from flowing to the interior of the drainage canal 1, and enables only water to flow to the interior of the drainage canal 1. Even when drainage water flows reversely through the drainage hole 3, since a firm adhering part 7 is firmly secured to the peripheral wall of the drainage hole 3, the firm adhering part is protected against separation from the drainage hole 3. | ||||||

| PURPOSE:To make construction work of an underdrainage easier by a method in which crushed stones are charged into a trench while running a crushed stone carrying car with a chute through which crushed stones are charged along the trench for drainage in which a shute is provided. CONSTITUTION:A water-permeable chute 3 is provided along the inner wall 2 of a trench 1 for drainage, formed by excavating the ground. Crushed stones 8 in the hopper 5 of the carrier base 4 of a crushed stone carrying car 9 are charged into the trench 1 through a chute 7 from a belt conveyer 6. | ||||||

| PURPOSE:To dry up wet farming land with good draining efficiency at low cost by a method in which the rich soil layer of a wet farming land is removed, a trench is excavated in the water-impermeable layer, excavated soil is mixed with a hardening agent and granulated, and the granules are packed into the trench and embedded with the rich soil layer. CONSTITUTION:The rich soil layer 1 of a paddy field is removed to expose a water-impermeable layer 2, and a trench 4 is excavated in the water-impermeable layer 2. The excavated soil of the trench 4 is put into a granulator, mixed with a hardening agent, and granulated to form granules 5. The granules 5 are put into the trench 4, and the trench 4 is embedded with the rich soil layer 1. Therefore, water in the rich soil layer 1 is separated through the apertures in the spherical granules 5 and drained with good draining efficiency without causing blocking even when used for long periods of time. | ||||||

| PURPOSE:To uniformly dry the soil for vegetation by ensuring the draining of even ground having bad draining efficiency by a method in which subtrenches are branched from the main trench of culvert type, and a water-collecting part is set in the sub-trenches connectedly to water collecting tubes in the main trench. CONSTITUTION:The main trench 2 is excavated from a high land to a low land by a trencher in the ground 1, and in the same way, subtrenches 3 are branched to form a housing trench 4 of a planar rib form. Vertical holes 5 are drilled in the crossing places between the main trench 2 and the subtrenches 3, and a water-collecting part 6 is inserted into the vertical holes 5. A perforated water- collecting tube 9 is set in the main trench 2 of the housing trench 4, and water- collecting tubes 10 as water-collecting parts are also set in the subtrenhes 3. Excessive water in the ground 1 is collected in the tubes 10 in the subtrenches 3 and also in the tubes 9 in the main trench 2 and then discharged from high land to low land. Water remaining on the surface of the soil 11 for vegetation is further collected in the water-collecting part 6 in the vertical holes 5 and drained. | ||||||

| PURPOSE:To prevent the drying of the surrounding ground of a water drain device by a method in which a space is formed below a trench on which a water drain device is to be placed, the openings at both ends of the space are closed with a cover with a through hole to form a supporting base, and water is stored in the space and oozing into the ground during a dry season. CONSTITUTION:A long supporting base body 16 of a nearly M-shaped cross section is integrally molded with a synthetic resin, and paired left and right spaces 20 are formed inside lower plates 24 constituting the inclined walls 18, left and right-handed side walls 19, and the bottom of the body 16. Then, the openings at both ends of the spaces 20 are closed with a cover 26 with a small through hole 30. In setting a water drain device, the supporting base is set, a drain pipe 8 is set in a trench 40, and the trench 17 is embedded with soil. Thus, water under the ground is discharged through a conduit 8 but part of the water flows into the spaces 20 through the through holes 30 and is stored. When the surrounding ground is dried, the water stored oozes the ground through the through holes 30 to prevent the overdrying of the surface layer of the ground. | ||||||

| PURPOSE:To exactly perform drainage work neither more or less by an automated drainage operation in which the interrupting plate of a drain port is opened or closed with a fixed period interval by the output signal of a photo sensor which varies at daytime and night. CONSTITUTION:A flexible cylinder 2 is provided in the hard cylindrical tube of drainage canal, an interrupting plate 3 is vertically moved inside the through hole 14 of the hard cylindrical tube 1, and the drainage canal is opened or closed. At night, output of a photosensor 17 becomes 1-signal, and thereby a motor M is turned, the interrrupting plate 3 is brought down, the hard cylindrical tube 1 is closed, and drainage is stopped. When the lowering of the interrupting plate 3 is ended, a limit switch 12 is operated by a cam 9, and the motor M is stopped. At daytime, the output of the photosensor 17 becomes 0-signal, and thereby the motor M starts its operation, the interrupting plate 3 is raised, the hard cylindrical tube 1 is opened, and drainage is started. When the rise of the interrupting plate 3 is ended, the limit switch 12 is operated by the cam 9 to stop the motor M. | ||||||
