Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a concrete gutter with a U-shaped cross section, which aims to accurately collect water from the road surface and to provide a concrete gutter that is easy to manufacture and stable in strength.

[0002]

[Prior art]

 Water collecting gutters for collecting and discharging rainwater and snowmelt water on roads have been widely used in the past.In recent years, concrete blocks have been used to create accurate and highly durable gutters. It is common to set. That is, a so-called U-shaped groove block or a gate-shaped groove block is used to form a gutter, and a lid made of concrete or the like is applied to the open top surface of the gutter. Water from the road surface is generally received in the groove by using the handle hole for removal as a water collection hole.

In a part of the U-shaped groove side groove block as described above, the above-mentioned lid width is provided on both sides of the concrete lid in parallel with the above-mentioned handle hole portion for the lid attaching / detaching operation. It is also practiced to introduce road surface water into the groove by using the handle holes on both sides in the direction as water collection holes.

[0004]

[Problems to be solved by the device]

 In the case where water is collected by using a claw hole formed at the end in the longitudinal direction of the lid provided at the top surface opening of the concrete gutter, there is a disadvantage that the water collecting action from the road surface cannot be sufficiently obtained. is there. That is, the above-mentioned hand-held hole at the end in the longitudinal direction has a small hole width in the longitudinal direction of the gutter, and the direction in which rainwater and the like flowing into the gutter due to the road surface gradient is greater than that in the gutter length direction. Since it is in a right angle direction, the catchment width must be small, that is, in the gutter cover, which is generally about 50 cm in length, it becomes a catchment hole 2 cm before and after the catchment width. It is difficult to drop or collect drainage.

In contrast to the conventional ones described above, in the case of collecting water by using the hook holes formed on both sides of the gutter lid in the length direction, the length direction of the hook hole is the road surface. Since it is orthogonal to the flow direction of the water flowing in due to the gradient, it is possible to take a water collection width of about 15 to 20 cm, which can enhance the water collection effect, but the concrete lid is on both sides of the cue hole. The concrete lid, which is inferior in bending strength (or tensile strength), runs on the gutter because it is locked on the gutter only by the locking portion of 10 to 15 cm (7 to 7 per concrete lid). When it receives 12 tons), a stress concentration part is generated in the center of the lid, and the possibility of breakage increases rapidly. In particular, the handle hole that also serves as a water collecting hole has to form a through hole that allows water to drop into the side groove, so that it is a recessed hole that is completely deeper than the locking step of the block main body. Since it is not locked to the stop, the total weight of the traveling vehicle acts and there is a high possibility of loss.

Further, since the joint setting between the block main body and the concrete lid forms the above-mentioned relationship, there is a large amount of rattling when the vehicle is traveling, noise is generated significantly, and the setting relationship is not stable.

Further, with the recent development and spread of cargo handling equipment, it is general that the length of the block body is about 2 m, while the length of the concrete lid to be operated by the labor of the worker is limited to about 50 cm. Therefore, when the number of concrete lids applied to each block body reaches many, such as four, some clear clearance is indispensable between those concrete lids, and such gaps are accumulated, so the block book There is an unavoidable error due to misalignment between the body's through hole and the concrete cover's hooking hole, which is disadvantageous because it is difficult to obtain the desired water collection capacity.

In order to avoid these disadvantages, it has also been proposed to embed a slit-shaped rectangular frame made of steel or synthetic resin partially rust-proofed in a concrete lid to reinforce and collect water. However, since the connection between the slit-shaped rectangular frame and the concrete lid cannot be accurately obtained, it is similar to the above that there is a high possibility of stress concentration and loss in the slit-shaped rectangular frame portion. Since the manufacturing of concrete lids requires extraordinary man-hours and requires expensive materials, cost increase is inevitable.

On the other hand, it is clear that the water collecting capacity can be sufficiently enhanced by adopting the steel lid grating, but this is 5 to 6 times as expensive as the concrete lid, and the gutter itself. Abnormally increase the cost. Moreover, since such steel grating is different from the concrete gutter body, special work is required for the concrete gutter body, such as its supporting step, in order to adopt it. Therefore, even if this grating is adopted, it is common that there is only one in a gutter of 20 to 50 m in case of heavy rainfall, and it cannot be used in general. Not only will it change, but there will be disadvantages that it will not be able to cope with heavy rainfall.

[0010]

[Means for Solving the Problems]

 The present invention has been studied to solve the above-mentioned problems in the prior art, and for the purpose of collecting water, which effectively solves the above-mentioned disadvantages by only a slight processing on the concrete block body forming the water collecting gutter. It succeeded in obtaining a road gutter gutter in a gutter block or a road, and is as follows.

(1) A pair of locking steps for mounting and supporting a lid are provided inside the tops of both side walls formed in a U-shaped cross section, and below the locking step in the height direction of the side wall. A road gutter gutter characterized in that a water collection groove having a bottom surface inclined in the thickness direction of the side wall is formed so as to reach the inner surface of the side wall along the width range of the locking step.

(2) Locking steps for mounting and supporting the lids are respectively provided inside the tops of both side walls formed to have a U-shaped cross section, and the side edges of the lids are received outside the locking steps. The road gutter trough described in the above item (1), wherein a vertical groove connected to the water collecting groove is formed at the formed rising portion.

(3) The road gutter gutter according to the above item (2), characterized in that an inclined edge for guiding water collection to the vertical groove is formed at the top edge of the partition wall between the vertical grooves formed on the side wall.

(4) An obtuse angle portion for guiding water collection in a water collecting groove direction is formed at a top edge portion of a lid placed and supported between opposing support steps. ~ Road gutters described in (3).

(5) A gap is formed between the upper edge of the rising portion formed outside the opposed locking step and the side edge of the lid supported by the locking step to collect water. The road gutter gutter according to (1) to (4) above, wherein an inclined surface for dropping is formed.

[0016]

[Action]

It is dropped from the side edge of the lid into the gutter trough through the water collection groove.

Locking steps for mounting and supporting the lids are respectively provided inside the tops of both side walls formed to have a U-shaped cross section, and the side edges of the lid are formed outside the locking steps. By forming the vertical groove connected to the water collecting groove at the rising portion, the water on the gutter is guided to the water collecting groove through the vertical groove and smoothly flows down into the gutter trough.

By forming an inclined edge for guiding water collection to the vertical groove on the top edge of the partition wall between the vertical grooves formed on the side wall, the water is collected not only in the vertical groove portion but also in the partition wall portion between the vertical grooves. It can be guided into the gutter, and a continuous catchment action can be obtained in the entire length direction of the gutter.

The obtuse angle portion for guiding the water collection in the direction of the water collecting groove is formed at the top edge portion of the lid placed and supported between the opposing support steps, and the top edge portion of the lid is gently curved. To collect or drop the collected water.

Inside the upper end of the rising portion formed on the outside of the opposite locking step, a gap is formed between the side edge of the lid supported by the locking step to drop the water collection. By forming an inclined surface for the drainage gutter, a water storage part for collecting water is formed along the side edge of the lid to efficiently guide the water on the gutter gutter into the gutter and drop it. Can be crowded.

In addition to the U-shaped groove for passing water through the locking step 3 and the gutter body 1, the bottom surface 12, the rising portion 13 and the vertical groove 15 are of course used. , The water collecting groove 14, the recessed hole 18 or the through hole 18a, the distinguishing wall 25 having the inclined top edge 25a, the bent portion 27 or the inclined portion 28 are all of a vertical shape with no expansion on the upper surface side. This kind of structure is used for molding concrete products of this kind in which concrete is filled and molded in a relationship in which the usage state as a water channel is reversed. Understand that filling and molding can be done easily by forming a protrusion.

In other words, even if it looks like a complicated structure with unevenness, the actual filling molding only needs to be performed by pouring and filling concrete between the inner and outer molds, and the simplicity and ease of its manufacture are It is clear that the water is sufficiently secured, and it is clear that the preferred water collection or the strength relation with the applied lid 4 is maintained. In addition, since the above-mentioned action can be exhibited without requiring any special member or material, a gutter trough having a special function can be obtained with a sufficiently low cost.

According to the present invention as described above, in an area where it is necessary to consider only a relatively small amount of rainfall, even if it is used in place of a general lid, water can be collected from the conventional handle. In comparison, it is possible to obtain a water collecting effect of 2 to 3 times.
