Description

  The present invention relates to a rainwater lid that is installed on a side of a road in order to guide rainwater on a road surface to the rainwater tank.

  A general road consisting of a roadway and a sidewalk has a gentle downward slope from the center to the sidewalk so that rainwater, etc., can be quickly drained from the roadway. . As shown in FIG. 10, a boundary block 82 with a step including a curb is installed at the boundary between the roadway portion 80 and the sidewalk portion 81, and rain water on the road surface is drained below the boundary block 82. A side ditch is provided, and in this side ditch, rainwater troughs such as persimmons for depositing earth and sand, pebbles and the like flowing from the road surface and permeation persimmons for infiltrating rainwater into the ground are arranged at predetermined intervals.

  Above these rainwater traps, a rainwater lid 83 for allowing rainwater on the road to flow in is installed. As such a rainwater lid 83, a rectangular outer periphery as shown in FIG. A metal grid-like lid (grating) having a structure in which a plurality of through-holes 84 are entirely arranged by dividing the inside of 83a vertically and horizontally by a plurality of grid members 83b is known.

  FIG. 11 is a plan view explanatory view showing an inflow state of rainwater when the rainwater hull lid 83 is installed on a road inclined downward in the direction of the arrow 85. As shown in FIG. 11, rainwater flowing near the sidewalk part 81 flows along the boundary block 82 in the direction of the arrow 86 from the higher side to the lower side due to the influence of the downward slope of the roadway part 80, and the sidewalk part 81 The rainwater flowing in a place near the roadway portion 80 away from the roadway is caused by the influence of the combined gradient of the downward slope in the direction of arrow 85 of the roadway portion 80 and the downward slope from the center of the roadway portion 80 toward the sidewalk portion 81. It flows in the direction of an arrow 87 that obliquely intersects the traveling direction of the portion 80 and flows into the through-hole 84 of the rainwater hull lid 83.

  However, the rainwater hull lid 83 shown in FIGS. 10 and 11 is simply a structure in which the orthogonal lattice members 83b are arranged on the entire surface in the vertical and horizontal directions, taking into consideration the flow direction of rainwater, the ease of inflow of rainwater, and the like. However, when it is placed on an actual road, there is a problem that the rainwater that is going to flow into the rainwater basket collides with the lattice member 83b, so that it is difficult for rainwater to flow in and the rainwater collecting ability is low. .

  In order to solve the above-described problem, Patent Document 1 discloses a rainwater lid having excellent rainwater inflow properties.

  This rainwater cover covers a region partitioned by the outer periphery of the rainwater cover into a first region located on the sidewalk portion side and a second region located on the roadway side. A plurality of first grid members are arranged in parallel to each other with a plurality of first inflow ports, and a plurality of second grid members are arranged in the second region in a direction obliquely intersecting the road. Thus, a plurality of second inlets are provided.

  However, even in the rainwater jar lid of Patent Document 1, when a large amount of fallen leaves flow along with the rainwater, the rainwater intensively flows in from the inlet near the outer periphery of the rainwater jar lid. The fallen leaves, etc. that have lost water accumulate in the vicinity of the outer peripheral edge, and it becomes a weir, and the inflow of rainwater to the rainwater lid is obstructed. As a result, there is a possibility that rainwater accumulates and overflows or floods. There was a problem.

  Embodiments of the present invention will be described below based on examples shown in the drawings.

Example 1
FIG. 1 is a top perspective view showing an installation state of a rainwater jar according to an embodiment of the present invention.

  The rainwater gutter lid 10 of the present embodiment is installed at predetermined intervals along the boundary block 20 arranged at the boundary between the roadway portion A and the sidewalk portion B. In this embodiment, the boundary block 20 has a rainwater inlet 21 on the side surface on the side of the roadway section A. The installation method of the rainwater jar cover 10 is well-known, For example, it installs in the receiving frame with a rectangular planar shape fixed to the ground with an anchor bolt so that attachment or detachment is possible. Below the rainwater lid 10 is a rainwater tank such as a tank for depositing earth and sand, pebbles, etc.

  As shown in FIG. 1, the rainwater fence 10 is divided into a first area 11 located on the sidewalk B side and a second area 12 located on the roadway A side at the time of installation. The first region 11 is provided with a long first inlet 13 that opens along the road traveling direction (arrow C direction) on the outer peripheral edge located on the side of the sidewalk B. A second inlet 14 is provided on the side of the roadway A from the inlet 13. The second inflow port 14 is provided only in the central region of the first region 11 so as to cover substantially the entire length in the width direction orthogonal to the traveling direction of the road (the direction of arrow C) in the first region 11. In the present embodiment, two lines are provided so as to be line symmetric with respect to the center line L in the direction orthogonal to the traveling direction of the road (direction of arrow C). Here, “substantially full length” means “substantially” because there is a portion where it is difficult to provide the second inlet due to the structure and function of the rainwater jar lid 10, and therefore the second inlet is provided over the entire length. It has the meaning to include the case where it can be identified as the case where it is completely provided over the entire length due to the action of the second inlet, which will be described later, and the range is naturally determined from the common general technical knowledge .

  Further, a water guide groove 16 that guides rainwater to the second inlet 14 is provided in the upstream area of the second inlet 14. In this embodiment, the inflow direction of rainwater flowing near the sidewalk part B into the rainwater lid 10 is the direction of arrow D in FIG. 1, and both end portions of the first region 11 are upstream regions. The water guide groove 16 is a bottomed groove having a depth d with reference to the upper surface of the rainwater jar lid 10 as shown in FIG. 2 representing the XX end surface of FIG. 1, and the depth d is constant. .

  A plurality of third inflow ports 15 are provided in the second region 12 in a direction that obliquely intersects the traveling direction of the road. The third inlet 15 is provided in a trapezoidal region near the central region of the second region 12. In FIG. 1, the second inlet 14 and the third inlet 15 are hatched to facilitate distinction from portions other than these inlets. As can be seen from FIG. 1, the second inlet 14 and the third inlet 15 are provided so as to be symmetrical with respect to a center line L in a direction orthogonal to the traveling direction of the road (the direction of arrow C). .

  In the upstream area of the third inlet 15, a water guide groove 17 that guides rainwater to the third inlet 15 is provided. In the present embodiment, rainwater flows into the second region 12 in the direction of arrow E that obliquely intersects the traveling direction of the road. Accordingly, both corner portions of the second region 12 on the roadway portion A side are upstream regions. Similarly to the water guide groove 16, the water guide groove 17 is also a bottomed groove having a certain depth d.

  Although not shown in the drawing, illustration is omitted on the upper surface of the rainwater jar cover 10 other than the areas where the inflow ports and the water guide grooves are provided, and a plurality of slip prevention protrusions are provided substantially uniformly.

  In the above configuration, the rainwater flowing in the direction of the arrow D along the road near the sidewalk B is the first inlet 13 and the second inlet 14 in the first region 11, and further the rainwater inlet 21 in the boundary block 20. It flows in order. Further, rainwater flowing in the direction of arrow E from the roadway portion A side flows into the third inlet 15 of the second region 12 in an orderly manner.

  And when fallen leaves etc. flow in with the rain water in the place near the sidewalk part B, the fallen leaves etc. flow into the second inlet 14 provided in the central area of the first area 11 by the flow of the rain water. When a large amount of fallen leaves flows, the fallen leaves accumulate on the second inlet 14, but in that case, the accumulated fallen leaves etc. lead to the first inlet 13 (the rainwater inlet 21 of the boundary block 20). Rainwater inflow channels are formed. On the other hand, when fallen leaves and the like flow along with rainwater from the side of the roadway A, the fallen leaves and the like accumulate on the third inlet 15 of the second region 12 by the flow of rainwater. In the present embodiment, since the third inlet 15 is provided in a trapezoidal region near the central region of the second region 12, rainwater from the second region 12 to the first inlet 13 and the boundary block 20 due to accumulated fallen leaves or the like. A flow path toward the inflow port 21 is formed.

  As described above, in the rainwater lid 10 of the present embodiment, no fallen leaves or the like are accumulated in the vicinity of the outer peripheral edge on the upstream side, and the rainwater inflow path to the rainwater inlet 21 of the first inlet 13 and the boundary block 20. Therefore, rain water on the road surface can be drained efficiently.

  In this embodiment, the rainwater gutter lid 10 is installed on the roadway section A side of the boundary block 20 having the rainwater inflow port 21. Thus, when installing in the roadway part A side of the boundary block 20 which has the rainwater inflow port 21, the 1st inflow port 13 does not necessarily need to be provided. This is because the rainwater inlet 21 of the boundary block 20 can also function as the first inlet 13. However, in order to drain rainwater efficiently, it is preferable to provide both the first inlet 13 and the rainwater inlet 21 of the boundary block 20.

  Moreover, when installing in the roadway part A side of the boundary block 20 which has the rainwater inflow port 21, when the 1st inflow port 13 is abbreviate | omitted, the rainwater flow of the boundary block 20 in the sidewalk part B side edge part of the 1st area | region 11 is carried out. It is preferable to provide a water guiding portion that guides rainwater to the inlet 21.

  A configuration example of the water guide portion is shown in FIG. 3 (a) is an example in which the water guide portion is an inclined surface 18a, FIG. 3 (b) is an example in which the water guide portion is an inclined groove 18b, FIG. 3 (c) is an example in which the water guide portion is an inclined ridge 18c, 3 (d) is an example in which the water guide portion is a notched step portion 18d. In short, the water guide section only needs to guide rainwater from the first region 11 to the rainwater inlet 21 of the boundary block 20, and various configurations other than the examples of FIGS. 3 (a) to 3 (d) can be adopted. FIG. 3 shows an example in which, when the first inflow port 13 is omitted, a water guide unit that guides rainwater to the rainwater inflow port 21 of the boundary block 20 is provided at the side of the sidewalk B of the first region 11. In the case where the first inflow port 13 is provided, a water guide portion can be provided in the same manner. In this case, the water guide section has a function of guiding rainwater to the first inlet 13.
