JP7237704B2 - U-groove panel - Google Patents

Description

TECHNICAL FIELD The present invention relates to a U-shaped gutter panel installed in a gutter for controlling the flow of rainwater in mountainous areas or for channeling business water in flat areas.

Recently, large amounts of rain have fallen in mountainous areas, causing many landslides and frequent large-scale floods. In addition, there have been cases where roads cannot be used due to the lack of roadside gutters, or crops cannot be expected to grow sufficiently due to the lack of agricultural irrigation canals. In these cases, using a concrete U-shaped ditch for waterways on slopes of mountainous areas, side ditches for roads, and agricultural irrigation canals is heavy and requires large-scale construction work. Since it tends to collapse easily, a foldable or assembled U-shaped groove panel made of plastic, which is light, convenient to transport, and easily assembled on site, has been devised.

Japanese Utility Model Publication No. 63-6298 JP-A-9-328806

Both the U-shaped structure in Patent Document 1 and the resin groove in Patent Document 2 are made of resin, and Patent Document 1 is of a folding type, and Patent Document 2 is of an assembly type. The one disclosed in Patent Document 1 has a plurality of V-shaped bent grooves 5 in its length direction, and the bent grooves 5 are bent to form a U-shape to enhance reinforcement and bending rigidity. For this reason, grooves 8 are formed in the width direction of the structure. This U-shaped structure is easy to assemble, but it is made of a single plate and is not strong enough. There is In addition, in Patent Document 2, a plurality of parts such as the bottom plate 31, the side plate 35, the lower side portion 11, and the upper side portion 21 must be assembled to form a structure. is also annoying.

The foldable U-shaped groove panel of the present invention consists of a bottom plate and two left and right side plates. The bottom plate and the side plates are composed of double walls. Occasionally, slanted walls facing each other and contacting each other are provided, one of the slanted walls is formed with a ridge, and the other of the slanted walls is formed with a recessed groove that engages with the ridge. preferably.

It is preferable that the ridges and the grooves extend to face each other in the direction of water flow.

Reinforcing grooves extending in the vertical direction of the side plate when the side plate is folded are formed in the inner wall and the outer wall forming the double wall of the side plate, and the reinforcing grooves formed in the inner walls of the left and right side plates face each other. It is preferable that a barrier plate for controlling the flow of water in the U-shaped groove can be detachably attached to the facing reinforcement groove, which is formed open at the upper end of the side plate at a position.

Moreover, it is preferable that the inner wall of the bottom plate is flat.

Also, the panel is preferably made of polyethylene.

The U-shaped groove panel of the present invention consists of a bottom plate and its left and right side plates, and since it is composed of double walls, it has sufficient strength, and since it is foldable, it can be flattened and transported. A ridge is provided on one of the slanted walls of the connecting portion between the bottom plate and the side plate, and a recessed groove that engages with the ridge is formed on the other slanted wall opposite to the slanted wall. The strength is also sufficient, and if the ribs and grooves are joined together, the side plates are held vertically, facilitating the installation work at the site.

In addition, since reinforcing grooves are formed in the outer and inner walls of the side plates, the strength of the panel is increased and the reinforcing grooves in the inner walls can also serve as detachable support grooves for the barrier plate for adjusting the flow rate of water. In addition, when the earth and sand along the side plates collapse and the flow of earth and sand along the left and right side plates deviates, the reinforcing grooves formed in the outer wall have less resistance to the flow of earth and sand than the convex body. Damage to the grooved panel can be prevented. Furthermore, since the bottom plate is formed flat, even if the panel is installed on flat ground for agricultural use, it does not interfere with the flow of water, and water does not remain in the grooves.

Furthermore, since the panel is made of polyethylene, it can be reused and the environmental load can be reduced.

Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, the U-shaped groove panel P of the present invention has a bottom plate 1 in its central portion, and two side plates 2, 2 on the left and right sides of the bottom plate 1 are foldable through connecting portions 3, 3. Concatenated.

The bottom plate 1, as shown in FIG. 7, consists of a flat inner wall 1a (in contact with water) and an outer wall 1b (in contact with earth and sand), and the side plate 2, as shown in FIG. This double wall is strong and has a space between the walls, so that the side plate can form a protrusion on the inner side of each wall and a protrusion on the earth and sand side. No need to stick out. That is, the inner wall 2a of the side plate 2 is provided with reinforcing grooves 4 at predetermined intervals in the direction of water flow. It also serves as an indicator groove for detachably supporting the barrier plate 5 for adjustment (Fig. 9). The outer wall 2b is provided with reinforcing grooves 6, 6 extending vertically when the side plate is folded up at predetermined intervals in the direction of water flow. When the earth and sand collapse and move in the direction of water flow, the resistance is small compared to the protruding projections, and even when the earth and sand flow in contact with the left and right side walls is deviated, the U-shaped groove panel will not break due to blocking. can be avoided.

In addition, the inner wall 1a of the bottom plate 1 is formed flat (no reinforcing grooves), so that even when the U-shaped groove panel P is installed on a flat ground, the flow of water is not hindered and water does not stay therein. can avoid. The bottom plate 1 and the side plates 2 are integrally molded by pouring polyethylene into a mold to form an integrally molded body having a predetermined thickness. .

As shown in FIGS. 3 and 4, the connection portion 3 is thin, flush with the outer walls 1b and 2b of the bottom plate 1 and the side plates 2, and has flexibility. a slanted wall 3b (bottom plate side) and a slanted wall 3c (side plate side) that widen at an angle of about 45 degrees; and a recessed groove 3e formed in the slanted wall 3c with which the body 3d is engaged. It is fixed to the bottom plate 1 and the side plate does not fall outward even if the side plate 2 is not pressed at the time of assembling, which not only facilitates assembly but also increases the strength of the connecting part. 10, the upper ends of the side plates 2 are fixed by a fixing plate 10 so that they do not open. The fixing plate 10 has engaging portions 11, 11 on both sides thereof, and each of the engaging portions 11 engages with the upper end surface of the side plate 2, and a holding plate 12 contacts the outer wall 2b and the inner wall 2a thereof; has 13.

Instead of the ridges 3d and grooves 3e of the connecting portion 3, as shown in FIG. 5, ridges 3f formed at intervals may be used. It may be something like a ridge 3g extending in the direction of inclination of the slanted wall 3b. Although not shown, grooves are formed in the slanted wall 3c facing the slanted wall 3b so as to correspond to the ridges 3f and 3g.

It can be used as mountain slopes, roadside ditches on level ground or agricultural waterways.
