Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a drainage ditch installed at the boundary between a sidewalk and a roadway or as a side ditch of a road.

(Conventional technology) An L-shaped groove is usually installed at the boundary between the sidewalk and the roadway.
Drainage is conducted through a catch basin into a U-shaped ditch installed below. However, in snowy areas, the surface layer of curbstones is often scraped away by snow removal equipment, which seriously impairs the aesthetic appearance, and when it rains, mud accumulates in the corners of the L-shaped groove, and when it dries, it repeatedly scatters, which is extremely harmful to the environment. be damaged. If grating is used as a cover for the U-shaped groove, the problem of poor water drainage will be solved, but the equipment will be expensive, and it will cause problems such as high heels getting stuck in, corrosion, and theft.

(Technical issue) Therefore, the present invention uses a slit type to take in water, mud, etc. from anywhere on the road and keep costs low, and also prevents heels and wheels from falling into the slits. This provides a drainage ditch that combines the following.

(Technical means) That is, the present invention has a groove main body 3 in which a slit 2 communicating with an internal water passage 1 is opened on the upper surface along the longitudinal direction.
and a curb 4 installed on the upper surface of the groove body 3. The front edge 5 of the curb 4 is fixed at the same position as the front edge 6 of the slit 2 or at a position further forward, and a part or all of the curb 4 is fixed. This drainage channel is characterized by having a water guide notch 7 leading to the slit 2 on the front lower edge of the drain channel.

(Example) The following will be explained using illustrated examples. The example includes a groove main body 3 having a passageway 1 with an arcuate bottom surface 8 inside, and three types: a standard type, a cut-down type, and a joint type of both types.
The groove main body 3 has a longitudinally extending slit 2 on the upper surface thereof, thereby introducing water etc. into the water passage 1. 9
10 is a slope for introduction formed on the upper surface of the main body in front of the slit 2, and 10 is a joint groove formed on the end face of the groove main body 1 so as to surround the water passage 1, into which a rubber joint material is fitted. Reference numeral 11 indicates a bolt hole provided on the inner upper side surface of the groove body 1, and reference numeral 12 indicates a recessed hole into which a bolt is inserted. The three types of curb stones 4A, 4B,
4C, the upper surface outside the slit 2 is the inclined surface 9.
It is installed as a lower mounting surface 13, and when installed, the curb stones 4A to 4C are placed at the joints of the groove main body 1 (FIG. 1), and are fixed to the main body 1 with a concrete adhesive 14. In addition, each curb 4A to 4C and the groove body 1 may be tightened using bolts, and in that case, bolt holes are formed in each of the curbs 4A to 4C and bolt holes are formed at important points on the groove body mounting surface 13. (not shown).

The slit 2 has a tapered cross-sectional shape that is narrow at the upper end (outer end) and widened at the lower end (inner end). A standard curb 4A is installed so as to cover it from above, and in the embodiment, the curb 4 has dimensions and an external shape such that its front edge 5 hits the front edge 6 of the slit 2 and closes the slit 2, but the standard curb 4A is Since the lower edge has a hook-shaped introduction notch 7 (a diagonal chamfered notch may be used) leading to the slit 2, a gap G is formed between the notch 7 and the inclined surface 9. This gap G is standard curb 4A
It connects and opens at the location, but not at the location of the connecting curb 4B and the cut-down curb 4C for vehicle entry (see FIGS. 4 and 5). The slit 2 may be formed over the entire length of the groove body 3, but in the example, joints 16 are provided at required parts such as both ends, so that the slit 2 has sufficient strength to withstand earth pressure after construction. ing. The gap G is narrower than the narrowest part of the slit 2, and is set to such a size that even if a high heel or a bicycle wheel tries to enter at an angle, it will not fit therein. Therefore, there is no risk of mud etc. clogging the middle. Further, in the embodiment, only the case where the front edges 5 and 6 of the curb 4 and the slit 2 coincide with each other has been described, but the front edge 6 of the curb may be made to protrude further forward.

(Operation of the invention) Therefore, in the proposed drainage ditch, the ditch main body 3 is installed on the ground where foundation work has been performed, while being tightened with bolts, and the necessary curb stones 4A or 4B are attached to the mounting surface 13 using adhesive 14. , 4C as described above, a gap G is opened on the road side through the slope 9 at the location where the standard curb 4A is installed on the main body, and a gap G is opened between the other curbs 4B and 4C. Since the slit 2 is closed, there is no problem with the entry of automobiles, etc., and rainwater, dirt, etc. are not allowed to enter more than necessary.

(Effects of the invention) Since the present invention is constructed and operates as described above, rainwater and mud on the road can be flowed into the water passage 1 through the slit 2 without accumulating as in the conventional L-shaped groove. As a result, there is no more dust on the road when it dries, and since each curbstone 4 is fixed to the groove body 3, it can be removed and replaced.
You can easily create a new entry point for cars or replace or repair a damaged curb.Furthermore, since the slit 2 does not open upward, unlike grating, high heels etc. do not fit into it. Moreover, the construction cost is lower than that of the grating type, which has a significant practical effect.
