Abstract

PURPOSE:To make easier the production of a drip hole device by providing slit-like apertures in both sides of the basal part of a vertical water-guide plate and also in the upper and lower part of the basal part of a cross water-guide plate for a pipe molded by an integral extrusion molding machine. CONSTITUTION:By molding an elemental material 11 (e.g., vinyl chloride, etc.) by an integral extrusion molding method, a vertical water guide plate 13 is formed above the pipe 12 of a hexagonal cross section, inwardly inclined cross water-guide plates 14 are formed on left- and right-handed both sides, and a reinforcing protrusions 15 are formed below the cross water-guide plates 14. Then, over the lengthwise direction of the pipe 12, slit-shaped apertures 16, 17 and 18 are formed in both sides of the basal part of the vertical water-guide plate 13 and also in the upper and lower parts of the basal part of the cross water-guide plates 14. Then, a spacer 19 is inserted into a space 20 between the downsides of the cross water-guide plates 14 and the upsides of the reinforcing protrusions 15 to bear soil pressure applying to the upsides of the cross water-guide plates 14. When such a device is buried underground, water flows on the surfaces of the water-guide plates 13 and 14 and is discharged from the apertures 16-18 to the pipe 12.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for efficiently manufacturing a drainage device that is buried in the soil and drains water contained in the soil.

The present inventor previously invented a water drainage device that can efficiently drain water from the soil (Japanese Patent Laid-Open Publication No. 1983-20812-). That is, as shown in FIGS. 1 and 2, two flat water guide plates 2.3 are placed below the vertical water guide plate 1, which has a substantially inverted Y-shaped cross section, and are slightly tilted inwardly. Ribs 6. with slit-like gaps 4.5 interposed between the water guide plates 1.2.3.
6, and further below the two flat water guide plates 2.3, a water guide pipe 8 having a substantially rhombic cross section with a gap 7 at the -1 part is connected to both flat water guide plates 2.3. 3 is fixed by ribs 10.1o with a slit-like gap 9.9 interposed between it and the lower surface of 3.

When a drainage device constructed in this way is buried in the soil,
The water contained in the soil around this device is
．． 3, flows further along the surface of each water guide plate, flows through the gap 4.5.9.7 into the water guide pipe 8, and is discharged through the water guide pipe 8. Therefore, if this drainage device is buried, it is possible to efficiently drain the moisture from the soil by −f+1.

By the way, when manufacturing a water draining device constructed and operated as described in -I-, conventionally, a plurality of water guide plates 1.2.3 and water guide pipes 8, which were separately manufactured, are bonded together via ribs 6.10. agent,
Alternatively, since they are connected by means such as ultrasonic welding, the manufacturing process of a long water draining device up to several meters in length is troublesome, leading to an increase in the price of the product.

SUMMARY OF THE INVENTION The present invention aims to provide a method for manufacturing a water draining device that can eliminate such inconveniences, facilitate the manufacturing of the water draining device, and provide an inexpensive product.

The present invention will be explained below with reference to drawings showing examples.

FIG. 3 shows a material 1 produced in the first step in producing a water removal device by the method of the present invention. This raw material 11 is made by integral extrusion molding of vinyl chloride, nylon, synthetic resin, etc., and a vertical water guide plate 13 is placed above the pipe portion 12 with a hexagonal cross section (the cross section shape is not particularly limited).
, horizontal water guiding plates 14.1 inclined inwardly on both left and right sides.
4 are formed respectively, and reinforcing ridges 15, ]5 are formed below each horizontal water guiding plate 14, 14 with a slight interval.

Next, as shown in FIGS. 4 and 5, slit-shaped gaps 16, 17, and 18 are intermittently formed in the material II thus formed in the tube portion 2 along the length of the material 11. Form. That is, the first gap 1 is provided on both sides of the base of the vertical water guide plate 13.
6.16, a second gap 17.17 on the two sides of the base of the left and right horizontal water guide plates 14.14, and a second gap 17.17 between the left and right horizontal water guide plates 14.
A third gap 18.18 of λ1 is formed below the base of each water guiding plate 13.14, and the water that has arrived at each water guide plate 13.14 enters the pipe portion 12 through these gaps 16, 17, and 18. It can be so. To form a slit-like gap like this,
Various conventionally known methods can be adopted, but in Example (3), as shown in the first gap 16 in FIG. Alternatively, as shown in the third gap 18 in the same figure, the tube wall between the elliptical holes drilled at intervals is cut with a cutter to form a series of these multiple circular holes. It can be formed by In addition, the lower surfaces of the left and right horizontal water guiding plates 14.14 and the reinforcing ridges 15.15
A spacer 19 is inserted into the space 20 between the upper surface of the holder and the upper surface of the holder, as shown by chain lines in FIGS. This spacer 19 supports the earth pressure applied to the "-" surface of the horizontal water guide plate 14.14 to prevent deformation of the water guide plate 14.14, and is located between the third gap 18.18. However, if the width of the horizontal water guiding plate 14.14 is narrow and deformation due to ground pressure is not a problem, the reinforcing ridges 15.15 and the spacers 19.19 may be omitted.

(4) As shown in FIG. 6, the material 11 also has vertical water guide plates 13 at the ends, horizontal water guide plates 14, 14 on the left and right sides, and reinforcing ridges 15.
15 is slightly removed to complete the water draining device. This is because one end connects this draining device to a drain pipe, so that the other end 15 does not get in the way.

This cutting operation is not necessary if the end of the water draining device extends directly out of the ground.

The method for manufacturing a water draining device of the present invention is to manufacture the water draining device as described below, so it is easier and cheaper to provide the water removing device than conventional manufacturing methods.
