In order to assemble the lid 2 at the factory or at the construction site when necessary, the site conditions such as the size of the site for laying the road D, the terrain, the hardness of the ground and the amount of rainfall, etc., the traffic volume of the vehicle, etc. In consideration of the above, a lid component plate suitable for the use described below is selected and assembled. The details of this assembling will be described below. For example, as shown in FIGS. 1 and 3, lids 4 and 4 each having a substantially rectangular cross section and a substantially rectangular plane and having the same thickness t are selected and arranged in parallel. A common grating member 5 is fitted into the slit 3 formed between the component plates 4 and 4 from below. In this case, provided the support portions 6a which overhanging the left and right support rods 6 which is integrally fixed to the lower surface of the horizontal plate 12 of the grating member 5 for each desired interval K _1, and 6a in the corresponding location of the bottom surface of the cover structure plate 4,4 The lid 2 is assembled by fitting into the groove formed.

The lid 2 assembled in this manner is stored in a warehouse and stacked or transported to a construction site.
Since the grating member 5 is integrated by assembling the two lid constituting plates 4 and 4, the grating member 5 is not accidentally detached due to vibration or external force from the vehicle during transportation. . Grating member 5
Are a plurality of, in the figure, three horizontal plate members 12 made of steel materials provided in parallel in the longitudinal direction X at intervals, and the horizontal plate members 1
A plurality for interval keeping made of steel which is provided for each desired interval K ₁ by the intersection in the longitudinal direction X with respect to 2, since it is formed in a planar grid pattern by, for example, seven vertical plate 13, the structure robust Thus, the lid constituting plates 4 and 4 can be strongly supported against tension, compression and torsion in any of the longitudinal direction X, the width direction Y and the height direction.

The lid 2 thus assembled in a factory or the like
In order to cover the side groove block main body 1 with the cover, the locking cylinder 1 embedded in the shoulders 1b ₁ , 1b ₁ facing above the side groove block main body 1 as shown in FIG.
9 is provided in the mounting hole 17 provided in the upper portion 15B
When the locking pin body 20 is hit with a hammer by inserting the leading end of the locking pin body 20, the small diameter portion 20 A provided at the leading end of the locking pin body 20 becomes a large-diameter mounting hole provided in the locking cylinder 19. 17
Is press-fitted into the small-diameter mounting hole 16 through the communication hole 18 communicating with the mounting hole 16. At this time, the lid 2 has not yet been covered by the gutter block main body 1.

Thereafter, when the locking pin body 20 is further hit with a hammer or the lid 2 is put on the gutter block main body 1 without hitting the locking pin body 20, the locking pin is caused by the impact force of the hammer or by the load of the lid 2 being applied. The large-diameter portion 20B of the body 20 is press-fitted into a large-diameter mounting hole 17 provided in the upper portion 15B of the locking cylinder 19, so that the locking pin body 20 is coupled to the locking cylinder 19.

The lid 2 is fitted into the side groove a and is fixed to the side groove block main body 1. In addition, although not shown, the cover 2 can be detachably fixed to the side groove block main body 1 by using an embedding bolt and a nut, and attached.

In this way, as shown in FIG. 3, when the gutter block main body 1 is continuously laid along the road D, and the cover 2 is covered and fixed, the rainwater falling on the road surface flows down to the road shoulder E. It is introduced into the side groove block main body 1 via the gray tag member 5 from the slit 3 formed entirely in the longitudinal direction X substantially at the center in the width direction Y of the lid 2. Therefore, it is possible to drain the water efficiently through the drainage channel 1a provided in the gutter block main body 1 without collecting rainwater or the like that falls on the road surface such as the road D. Therefore, even if the amount of rainfall is large, the drainage is performed without flooding the road D or overflowing the shoulder E with rainwater.

Further, the lid 2 having a substantially rectangular cross section and having the same thickness t, t is covered and attached to the side groove block main body 1 as described above, so that even if a load is applied by the running of the automobile, it is applied. There is no collision sound that the lid 2 collides with the gutter block main body 1.

In addition, the lid 2 is formed on a road laying ground having a limited area because the lid constituting plates 4 and 4 are formed in a substantially rectangular cross section with the same thickness t and t, and the upper surface is formed as a flat surface. When the road is formed or the road D is renovated, the width of the road D can be sufficiently secured, and the vehicle can be driven safely. Moreover, since the slit 3 formed between the lid constituting plates 4 and 4 of the lid 2 and into which the grating member 5 is fitted is provided continuously to the lid 2 along the road D, it becomes obstructive when the vehicle travels. Without this, the visibility ahead is ensured, which can contribute to safe driving.

FIGS. 10 and 11 show that the upper part of the grating member 5 is slightly projected at the time of assembling by forming _one lid constituting plate 4 having a substantially rectangular cross section with the same thickness t ₁ which is smaller than that described above. At the same time, the other lid constituting plate 4 'is formed in a substantially trapezoidal cross-section having an inclined surface 7 facing the slit 3 provided on the upper surface, so that the lid constituting plates 4 and 4' differ in width and width Y intersecting with the longitudinal direction X. width W _1, to form a flat, substantially rectangular W ₂ slits 3 lidding plate 4, 4 'in addition be formed by displacement than a substantially central over the longitudinal direction X of the two lidding plate 4, 4' Among them, the curb block 30 was provided in the longitudinal direction X on the upper surface of the lid constituting plate 4 provided on the sidewalk J side. The modified example is that the gutter block main body 1 is laid along the road D, and the road D and the sidewalk J can be laid separately by the curb block 30 by effectively utilizing the limited road laying site. This is a different configuration from that described above, and has an operation and an effect.

FIG. 12 shows a third modified example of the lid 2 in which different kinds and irregularly shaped lid constituting plates are assembled by using a common grating member 5. That is, the lid component plate 4 provided on the side far from the road D is formed in a plane substantially rectangular shape having the same thickness t with a substantially rectangular cross section as shown in FIG. slit plane substantially rectangular lidding plate 4A of the different shape with respect to the cover structure plate 4 forming a trapezoidal cross section having a slope portion 7 of the downward slope theta ₁ facing the slit 3 on the upper surface on the side close to the road D 3 are arranged in parallel with each other, and the shared grating member 5 fitted in the slit 3 has a desired spacing K _1.

[00 43]

As described above, according to the present invention, the lid covered by the drainage block main body can be provided with a lid member having the same or different cross-section through a slit extending in the longitudinal direction. As a result, it is possible to selectively assemble in a factory or the like so as to be suitable for the application in consideration of the situation on the site. In addition, since a slit is formed between the lid component plates, rainwater or the like that has rained on the road flows down from the road surface to the shoulder according to the cross slope, is introduced into the drain groove block through the slit, and is efficiently drained. . In addition, since the slit is formed continuously with the lid laid along the road, the driver is obstructed by the discontinuity of the handle hole like a conventional gutter cover with a handle hole, and it is visually obstructed forward. It can contribute to the safe driving of the vehicle without impairing the performance.
In addition, since the lid is mounted so as to be covered by the drain groove block, noise due to collision with the drain groove block does not need to be generated, and inconvenience such as generation of chips at the end of the lid constituting plate does not occur. Further, the shape of the molding die of the lid constituting plate is simplified as compared with the conventional one, and one lid is formed at a length corresponding to some of the conventional gutter lids, so that it can be manufactured at low cost. In addition, since the grating member has a different shape, the lid is assembled for the lid component plate of a different shape, and the lid is assembled.
Material and equipment costs are reduced, and product manufacturing costs are reduced.
