Abstract

<P>PROBLEM TO BE SOLVED: To provide a simple sluice for a field which is buried in a ridge between an irrigation/drainage channel and a rice field surface, which prevents leakage of water of the ridge on the periphery of an installed sluice, and which is fixed in the location where it is installed. <P>SOLUTION: A flange 2 is provided on the outer periphery of one end part of a flume body 1 of needed lengths in the longitudinal direction, and the flume body 1 has a U-shaped vertical cross sectional view. Then two pairs of inner grooves 5 are vertically provided reverse to each other on the inner surfaces of both of the side walls 4 at needed intervals. Then a flume 7 formed by vertically providing an outer groove 6 on the outer surface stops and drains water by engaging a water-stopping plate 8 with the inner groove 5 with flexible removability. Then the outer water-stopping plate 9 engaged with the outer groove 6 performs positioning of the flume body 1 in the ridge 14 in collaboration with the flange 2. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a sluice buried in a field fence.

An example of a sluice that takes water from the drainage channel and stops the water in the field across the field fence is disclosed in Japanese Patent Laid-Open No. 2001-348850 (Patent Document 1). In the sluice of Patent Document 1, one side surface of a bench flume having a U-shaped longitudinal section is cut off to form a side surface portion, and a water stop plate is attached to a recess formed facing the inner side surface of the side surface portion. A cylindrical water pipe is welded to a through hole provided in the plate, and the through hole can be freely opened and closed by a lid member provided in front of the through hole.
Since the sluice gate is integrated with the irrigation drainage channel, there is a problem that a large construction is required to use it as a sluice gate between a general intake channel and the rice field and between the rice field and the irrigation channel.
JP 2001-348850 A

  The present invention seeks to provide a simple sluice for a farm that is buried in a ridge between a drainage channel and a paddy surface, prevents leakage of ridges around the installation, and is fixed at an installation position.

The simple sluice gate for a farm according to claim 1 is U-shaped in a longitudinal sectional view, and a flange is provided around one end in the longitudinal direction of a flume body having a required length, and inner grooves are opposed to inner surfaces of both side walls. The outer surface includes a flume having an outer groove provided vertically, a water stop plate that is detachably fitted to the inner groove, and an outer water stop plate that is fitted to the outer groove.
The invention described in claim 2 is a simple sluice for a farm described in claim 1,
A connecting flume having the same vertical cross-sectional shape as the flume main body and a required length is connected to the other end surface in the longitudinal direction of the flume main body through mutual connecting means.
According to a third aspect of the present invention, in the simple sluice for a farm field according to the second aspect, a slope having a downward slope is formed on the upper surfaces of both side walls of the outer end portion of the connection flume.

  According to the simple sluice gate for a farm of the present invention, the flange 2 of the flume body is easily positioned and fixed by the outer water stop plate fitted into the flange and the outer groove and driven into the soil. The water stop plate 9 prevents leakage from the side and bottom of the main body of the flume and prevents the slope from collapsing. If the ridge width is long, it can be handled by connecting the connecting flume to the flume. The water-stop plate to be fitted is water-tight with the inner groove due to the expansion of the wood, and can be stopped, and the outer end of the connecting flume protrudes from the inclined block on the side surface of the ridge. Is formed on the inclined surface, there is an effect that the appearance is harmonized with the inclination of the inclined block.

  The inner and outer grooves, which are vertically installed on the inner and outer surfaces of the side walls of the precast concrete flume body, each have a wide outer end (20 mm), a required depth (10 mm), and a required bottom width (15 mm) taper. The connecting portion of the flume body and the connecting flume is formed by fitting a convex line continuously provided on the inner end face of the connecting flume into a concave groove provided continuously on the other end face of the flume main body. The length of the connecting flume in the longitudinal direction ranges from a short one to a long one, and there is one in which a cover plate is covered on the upper surface opening of the flume and the connecting flume.

  An embodiment of a simple sluice A for farms according to the present invention will be described. As shown in FIG. 1, a flange 2 is provided around one end portion of a flume body 1 having a U-shape in a longitudinal sectional view and a required length, and the other end surface. The groove 3 of the connecting means is recessed in the U shape on the inner peripheral surface, and the tapered inner grooves 5 are vertically opposed to the inner surfaces of the side walls 4 at two required intervals, and the outer surface is also tapered. Each of a flume 7 in which an outer groove 6 is vertically opposed to a substantially middle position between the inner grooves 5, a water stop plate 8 that is detachably fitted to both ends of the inner groove 5 and water is stopped. It consists of an outer water stop plate 9 that is fitted in the outer groove 6 and positioned in the longitudinal direction in cooperation with the flange 2.

  As shown in FIG. 2, the connecting flume 10 connected to the other end surface of the flume main body 1 is U-shaped in the same longitudinal section as the flume main body 1 and has a groove 3 of the flume main body 1 at one end surface (inward end). Convex part 11 as a connection means fitted in is provided in U shape.

As shown in FIG. 3, the long connecting flume 12 is U-shaped in the same longitudinal section as the flume main body 1 and is longer than the connecting flume 10, and the upper surfaces of both side walls 4 at the outer end thereof are inclined downwardly. It forms as a surface 13 and is provided with a convex portion 11 fitted in the groove portion 3 of the flume body 1 in a U shape on one end surface thereof.
In the case where the width of the ridge is short, a simple sluice for a farm composed of a flume 7 in which the groove 3 is not formed on the other end face of the flume body 1 shown in FIG. 1, a water stop plate 8, and an outer water stop plate 9 ( (Not shown) is provided.

As shown in FIGS. 4 and 5, the farm sluice A constructed as described above has the flume 7 embedded in the recess 15 in which the ridge 14 is dug in the width direction and the flange 2 faces the rice field 16. The outer water stop plate 9 having one end fitted in each of the outer grooves 6 on the outer surfaces of the side walls 4 is also embedded, so that the flange 14 can be positioned in the width direction in cooperation with the flange 2. Both ends of each water stop plate 8 are fitted into the two inner grooves 5 to stop the water on the surface 16. When pulled up, the water on the surface 16 is guided to the guide groove 18 of the inclined block 17 provided on the outer slope of the ridge 14 and drained to the drainage channel 19.
As shown by the phantom lines in FIG. 5, the use of the connection flume 12 having the inclined surfaces 13 formed on the upper surfaces of the side walls 4 on the projecting end side of the connection flume 10 makes it possible to adapt to the inclination of the inclined block 17 and to harmonize the appearance. A lid plate (not shown) is covered with the openings on the upper surfaces of the flume 7 and the connecting flumes 10 and 12.

  The simple sluice gate for agricultural fields of the present invention can be easily constructed without being limited to the drainage channel in the fence between the existing drainage channel and the paddy field or the paddy in the newly established farm field, and therefore, wide demand can be expected.
