Abstract

PURPOSE:To effectively perform draining work for ground by a method in which water conveyance plates are radially set and connected in a trench, a water drawer fixed with an upside-opened tube is set below the water conveyance plates, the trench is embedded with soil to the water conveyance plates, a flat plate is bonded with the upside of the water drawer, and then the water drawer is buried in soil by embedment. CONSTITUTION:Plural water conveyance plates 1-3 are radially connected with small apertures 4 among their inside edges as a water drawer on the bottom of a trench 15. An upside-opened tube 6 is fixed to the lower part of the plates 1- 3 in such a way as to form small apertures 5 between the tube 6 and the plates 2 and 3, and the end of the tube 6 is connected to a drain pipe 8 connected to the drain dich. Broken stones 16 are charged to the plates 2 and 3 to bury the trench 15, and the downside of the inside corners of flat plates 18 is bonded with the outside corners of the upside of the water conveyance plates 2 and 3 buried. Broken stones 16 are further charged into the trench 15 to bury the water drawer 7 and covered with the same soil as the ground's surface. Water exuding into the underground can be effectively collected and drained.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a drainage construction method for baseball fields, track and field stadiums, tennis courts, and other grounds to improve water drainage.

(Background Art) The present inventor has previously invented a water drainage device that can efficiently drain underground water (Japanese Patent Application Laid-open No. 55-20812). The plates 1.2.3 are connected radially and with slit-like gaps 4.4 between their inner edges by integral ribs 14 as shown in FIG. A water guide @6 which is open at the top is fixed with a narrow gap 5.5 provided below the water guide plate 2.301. As shown in FIG. 3, the draining device 7, which is constructed in a relatively small size, connects the end of the water conduit 6 to the side surface of a drainage pipe 8, which is larger than the water conduit 6 of the draining device 7, as shown in FIG. The water collected by the water draining device 7 is collected in a drainage pipe 8 and is sent to a drainage ditch or the like.The drainage pipe 8 consists of a pair of flat plate parts 10.with a gap 9 between them. Outward inclined walls 1], 11 each having a flat outer surface are connected to the lower surface of 1.0, and the inclined walls 1], 1 are connected to each other.
A vertical wall 12.12 hangs from the lower end of each of the vertical walls 12.12, and an inwardly inclined wall 13 extends from the lower end of the vertical wall 12.12.
．． 13 are continuously formed, and the inwardly inclined wall 13.1
The lower ends of 3 are continuous with each other, and the water draining device 7
Upper sloped wall with a flat outer surface] 1. Drill a hole in the moon,
A water guide pipe 6 is directly inserted into the through hole and connected to the drain pipe 8. However, the vertical wall 12 in the middle of the drain pipe 8 may be omitted, and the upper end of the lower inclined wall may be directly connected to the lower end of the upper inclined wall 11.

Furthermore, as shown in FIG. 4, at the -L portion of one drainage pipe 8, an integral rib 14a is provided with a slit-like gap provided between the inner edges of the water guide plates 1a-s, 2as, and 3a.
By fixing through K, a large-sized water draining device 7a having the drain pipe 8 as a component is constructed.

As shown in Fig. 5, such a drainage device 7 (or ?a) is placed at the bottom of a trench 15.15 dug in the ground, etc., and the surrounding area is first filled with crushed stones 16, and then the trench is opened. 15
．． It is used by filling the upper part of 15 with ±17, which is the same as the surface of the ground etc. Moisture that seeps into the soil due to rainfall, etc.
The water flows through the surface of the water guide plate 1.2.30 of the water draining device 7, flows into the water guide pipe 6 through the slit 4.5, and is discharged, so water drainage from the ground etc. is good and the water can be drained until it can be reused after rain. Time is reduced.

By the way, in order to be able to perform the water extraction by the water draining device 7 even better, each water draining device N7.7
In aK, water guide plate installed in the horizontal direction 2.3.2a%
It is effective to widen the width of 3a. However, if you simply widen the width of these water guide plates 2.3.2a and 3a, the water draining device 7.7a will become bulky, so it may be difficult to store it in a warehouse or pack it. Handling becomes troublesome when transporting the product.

(Objective of the present invention) The present invention solves the above-mentioned disadvantages, and
-Water plate 2.3.2a of normal width as shown in Figure 4
It is an object of the present invention to provide a drainage construction method for grounds, etc., which makes it possible to more effectively collect moisture seeped into the soil by using a water draining device 7.7a having a water draining capacity of 7.7a.

(Structure of the present invention) The drainage construction method for grounds etc. of the present invention first places the water drainage device according to the previous invention at the bottom of a trench dug in the grounds etc.
Next, fill this groove with sand or crushed stone in the horizontal direction at the position of the water guide plate, and after gluing the inner twill part of the flat plate to the top surface of this water guide plate to extend the substantial width of the water guide plate, crush the entire flat plate. The drainage device is filled with the same soil as the -hK ground surface, and the groove is filled with the same soil as the -hK ground surface.

(Embodiments of the present invention) Next, the present invention will be explained in more detail by explaining the illustrated embodiments. Fig. 6 shows a first embodiment of the present invention.

First, the water draining device 7 according to the earlier invention described above is placed at the bottom of a groove 15 dug in the ground, etc., and crushed stones 16 are placed in the groove 15 up to the position of the horizontal water guiding plate 2.3 of the water draining device 7. Fill the lower part of the groove 15 and prevent the draining device 7 from falling down. Next, each of the above water guide plates 2.3
A flat plate 18 made of synthetic resin or the like is placed on the outer corner of the upper surface of the .
1. Glue the lower surface of the inner corner of 8 with instant adhesive. Next, crushed stones are again put into the groove 15 until the draining device 7 is filled, and the crushed stones are further covered with the same soil as the ground surface.

For this reason, of the water that seeped into the soil, water guide plate 2.3
Moisture that is not directly collected on the upper surface is also collected on the upper surface of the flat plate 18.
3, flows into the water conduit 6 through the slit 4.4, and is discharged.

Next, FIG. 7 shows a second embodiment in which the drainage method of the present invention is applied to the large water draining device 7aK shown in FIG. 4. This second embodiment is also constructed in the same manner as the first embodiment described above, but the rib 14a is provided over the entire width of the water guide plate 2as3a, and the water guide plates 2a, 3a and the flat plate 18.
Since the contact area with 8 cannot be secured sufficiently, each flat plate 18
As shown in FIG.
Notches 19 and 19 into which the ribs 14a are fitted are provided in accordance with the pitch of the ribs 14a, and the flat plate 18 is connected to the ribs 14a.
It is designed so that it can be inserted even inside a.

Other configurations and operations are the same as in the first embodiment described above.

(Effects of the present invention) In this way, by gluing a flat plate to the upper surface of the water guide plate during the burying work, the width of the water guide plate in the horizontal direction that constitutes the water drainage device is increased, so that the water drainage device itself does not become bulky. This makes it possible to more effectively collect moisture that has seeped into the soil.
