Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an upper surface closed side groove block provided on a road side at a boundary between a sidewalk and a permeable pavement road.
[0002]
[Prior art]
Conventionally, an upper surface closed side groove block is connected in the longitudinal direction to a boundary portion between a road and a sidewalk, and road surface water is taken into the block from gratings arranged at predetermined intervals.
[0003]
However, on a permeable pavement roadway, surface water permeates underground between the gratings and enters the perimeter block from the permeated water intake opening on the roadway side of the gutter block. Prevented.
[0004]
Then, in order to filter the earth and sand flowing in with the water flowing from the infiltration water inlet, the outer opening of the inlet is closed with a metal filter (wire mesh, mesh, expanded metal, etc.), and the above block is placed in the ground on the roadway. Was buried.
[0005]
However, the work of burying the gutter block in the roadway with the above-mentioned intake opening closed requires manpower and not only causes the overtaking work, but also if the intake opening is not blocked by the filter, Sand, gravel, pebbles, etc. flowed and accumulated in the gutter, causing clogging of the gutter and causing flood disaster.
[0006]
Therefore, a conventional method of nailing or bonding the outer peripheral surface of the metal filter to the outer peripheral surface of the inlet opening after molding the side groove block to block the inlet opening in advance has been adopted.However, the filter is nailed or bonded to the cement concrete gutter block. The construction is not easy, requires time and skill, and there is a defect that the filter is easily detached from the small inlet after the construction and cannot be used.
[0007]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION The present invention has been made in view of the above-described defect, and is only to cast ready-mixed concrete between a mold (outer frame) and a core. An object of the present invention is to bury the outer periphery and securely close the upper end opening of the water guide hole with the filter.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a gutter block in which the upper surface is closed and a space is provided therein, the upper ends of a plurality of water guide holes are opened at the upper side of the road side, and the lower ends of the water guide holes are connected to the block. The filter is formed integrally with the block in a state in which the outer periphery of the metal filter is embedded in the inner periphery of the upper end opening of the water guide hole, and the outer periphery of the filter is formed by a metal plate. The upper portion of the metal plate is bent in a direction perpendicular to the side of the road toward the inside of the block, and the bent portion is formed of a water-permeable hole and a water-permeable side groove block bent to reinforce the upper part of the upper end opening .
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
As shown in FIGS. 1 (a) and 1 (b), the side groove block 1 whose upper surface 1 "is closed has the side surfaces 1 'on both the sidewalk side and the road side, and the upper surface 1" is slightly upward horizontally or on the road side. Incline.
[0010]
A space s is provided inside the block 1, the bottom surface of which is an upward concave arc shape and a small curvature arc-shaped small groove 1a is formed at the center, and both side surfaces 1 'are shown in FIG. As shown in FIG. 5, a plurality of water guide holes 2 that are upright and communicate the upper part of the roadway side surface 1 ′ and the space s are formed to be inclined downward toward the space s.
[0011]
The block 1 supports a water guiding hole punching die shorter than the length of the water guiding hole 2 between the core for the space s and the outer frame toward the core from the core toward the outer frame. A metal filter 3 having an outer periphery larger than the outer periphery of the core is disposed, and a male mold for forming an upper end opening 2 ′ of the water guide hole 2 and a film for preventing filter clogging are provided between the filter 3 and the outer frame. Alternatively, a sponge sheet or the like is disposed, and a fresh concrete is poured between the core and the outer frame to form and harden the upper-side closed-side groove block 1, and the mold is removed to obtain a product.
[0012]
The male mold is removed together with the outer frame, and the water hole removing die is removed into the space s after the core is removed and removed. Further, the core can be extracted from the water guide hole as the core, which can be freely expanded and contracted, is reduced.
[0013]
The lower end opening of the water guide hole 2 opens on the upper inclined surface of the space s, and is inclined upward toward the roadway-side upright surface 1 ', and the upper end opening 2' is shown in FIGS. 1 (a) and 2 (a). 3) (a), (b) and (c), the outer periphery 3 'of the metal filter 3 is embedded in the inner periphery of the upper end opening 2'.
[0014]
A wire mesh, mesh, expanded metal, punched metal, or the like is used for the filter 3. An annular (round, square, etc.) metal plate 4 is arranged on the outer periphery 3 ′, and the plate 4 and the outer periphery 3 ′ of the filter 3 are arranged. The metal filter 3 is welded to form a single metal filter 3. However, only the central portion of one plate 4 may be formed of a punched metal (perforated plate) and the outer periphery may be formed of a non-perforated metal plate. The material is not limited to a material, such as rust-proof painting, plating, or the like, or stainless steel or other metal.
[0015]
Further, as shown in FIGS. 3 (a) and 3 (b), the upper part of the plate 4 is bent toward the inside of the block 1 in the direction perpendicular to the side surface 1 'on the road side, and the bent portion 4' The upper part of the upper end opening 2 'can be reinforced (FIGS. 3A and 3B).
[0016]
Reference numeral 5 in the figure denotes lower cutouts on both side surfaces 1 'and 1', and reference numeral 6 denotes a sidewalk curb block fitting step.
[0017]
【The invention's effect】
Since the present invention is configured as described above, in a water-permeable side groove block (inverted water-permeable side groove block) in which a plurality of water passage holes are opened on the road side surface of the upper surface closed side groove block, inflow of sediment from the water passage hole is prevented by a filter. Obviously, it is not necessary to separately perform a filter construction at the time of the gutter block construction, and the permeable gutter block provided with the filter can be simply and reliably constructed only by burying the gutter block. effective.
(1) By manufacturing a filter with a metal plate by attaching it to a mold in advance, it is not necessary to attach the filter later.
(2) Since the filter and the product are integrally formed, the filter does not fall off.
(3) By using a metal filter, it is possible to sufficiently withstand the temperature of the pavement asphalt, and there is no melting.
(4) Since the filter was made of metal, the filter became strong.
(5) Since the filter is made of metal, the wire diameter and opening of the mesh can be arbitrarily selected.
(6) The attachment of the metal plate provides reinforcement around the water collecting opening.
[0018]
or,
(1) By bending the upper part of the metal plate, the water collecting opening can sufficiently withstand the load from the upper part of the product.
(2) Since the water collecting opening can sufficiently withstand the load from the upper part of the product, it is possible to increase the diameter of the opening and improve the water collecting function.
(3) Since the water collecting opening can sufficiently withstand the load from the upper part of the product and also serves as a reinforcement around the water collecting opening, the water collecting opening is freely provided at any position up to the upper side surface. Can do things.
