Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a structure of a transverse groove block, and when a road itself has a slope (longitudinal slope), the block forming the transverse groove while maintaining a continuous flat slope matching the slope. Regarding the structure.
[0002]
[Prior art]
Roads are equipped with various facilities to encourage drainage of rainwater. The crossing groove is one of them, and it can be said that a structure equivalent to a normal U-shaped gutter (a gutter arranged in parallel with the road) is laid in such a manner as to cross the road. A grating may be placed to cover the upper opening, but is often only partially loaded for cost and other reasons.
[0003]
4 (a) and 4 (b) are schematic cross-sectional views showing one example of such a conventional crossing groove (cross-sectional view in a direction traversing a road), in which leveling concrete B is cast on a foundation crushed stone layer A. After that, in the example of FIG. 7A, a U-shaped block D is placed on the mortar layer C via the mortar layer C, and in the example of FIG. The bottom plate F is formed by flowing concrete. In each case, a grating G is fitted into the top end.
[0004]
[Problems to be solved by the invention]
In the case where the road is horizontal as shown in FIG. 4, there is no problem with the illustrated crossing groove, but in reality, and especially in the case of a forest road, an agricultural road, etc., a crossing groove is laid on a slope (a road having a vertical slope). Not a few.
[0005]
In such a case, the transverse groove is laid as shown in FIG. That is, the top end portion of the crossing groove is installed horizontally, and road slopes x and y are formed from both ends thereof.
[0006]
Therefore, the slope changes between the top horizontal part of the product section and the pavement surface constructed along the road slope, and when the vehicle passes through it, there is a bounce shock and it is uncomfortable and sometimes dangerous. It is.
[0007]
Also, as is clear from FIG. 5, the road slope x and the road slope y are displaced from each other by a distance d because a horizontal portion exists on the slope where the transverse groove is provided. Therefore, it is not easy to cut off a part of the road surface and lay the crossing groove as an additional work after the pavement, and the cost tends to be high.
[0008]
[Means for Solving the Problems]
In view of these points, the present inventor has finally made the present invention as a result of earnest research, and the features of the present invention are a U-shaped block that opens upward, a lid block with a through hole that covers this opening, and Wherein the upper surface of the lid block is inclined at a certain angle with respect to the top surface of the U-shaped block when installed on the U-shaped block.
[0009]
Here, the “U-shaped block” is a concrete block having a “U” -shaped cross section, and its basic structure is a U-shaped block employed in a conventional transverse groove [for example, the U-shaped block D in FIG. ]. However, in the case of the conventional U-shaped block, the top end forms a part of the road surface, and when the grating is provided, the top end is fitted into the top end portion, whereas in the U-shaped block of the present invention, the top end is formed. Since the lid block is covered, there is a difference in structure and construction time due to this. For example, a coupling structure with the lid block is provided at the top end of the U-shaped block so that the vehicle does not shift even when passing over the lid block, and furthermore, the vibration noise is reduced. Will do. The details are not limited in the present invention.
[0010]
As described above, the “lid block” is a concrete block placed on the U-shaped block, and this structure is the most important feature of the present invention. That is, when the upper surface of the lid block is installed on the U-shaped block, the upper surface is inclined at a constant longitudinal gradient with respect to the top end surface of the U-shaped block. The U-shaped block itself is constructed so that the bottom plate is horizontal and the side plates are vertical as much as possible, so that the top end surface is also horizontal. Therefore, in the present invention, this lid block corresponds to the vertical gradient of the road.
[0011]
Since the surface of the lid block has an inclined surface that matches the vertical gradient of the road, the thickness of the front and rear ends is different, and thus the vertical cross-sectional shape is generally substantially trapezoidal. However, the structure is not limited to the “trapezoidal shape” because it may be a structure that cannot be said to be a trapezoidal shape, for example, by adopting a rib structure to reduce the weight.
A through hole for collecting water is provided on the surface. This through-hole may be one in which a hole or a slit is provided in the block itself, or may be formed by fitting a separate grating. Since the vertical gradient of the road is naturally not one kind, a plurality of kinds of inclination angles of the upper surface of the lid block are set.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in more detail with reference to the drawings. The drawings are all examples, and the present invention is not limited only to the illustrated structures, shapes, sizes, and the like.
[0013]
FIG. 1 shows an example of a sloping transverse groove block 1 (hereinafter referred to as “the present invention block 1”) according to the present invention. As is clear from the drawing, the present invention block 1 comprises a U-shaped block 2 and a lid block. 3 is a concrete block. The size of each of the U-shaped block 2 and the lid block 3 is 2,000 mm in length and 500 mm in width. The height of the U-shaped block 2 is 400 mm. Further, the lid block 3 has a trapezoidal cross section and different heights at both ends. The lower one is 110 mm and the higher one is 160 mm. This size is for a road with a vertical gradient of 10%, but by preparing several types of differences in height, it is possible to cope with various gradients. It is also convenient to arrange several types of vertical and horizontal lengths.
[0014]
The lid block 3 also has a single groove 31 on the upper surface thereof, and a plurality (four in the illustrated example) of upper and lower through holes 32 at the bottom of the groove 31. The metal grating 4 is fitted into the concave groove 31. Although it also has a grating fixing insert and a bolt hole for attaching a hanging bracket, it is not shown.
[0015]
FIG. 2 is a vertical sectional view of a main part of a road constructed using the block 1 of the present invention. The road is a slope having a vertical gradient of 10% as described above, and the upper surface of the lid block 3 and the road slope completely match. Further, in this example, the connection and integration of the U-shaped block 2 and the lid block 3 are performed by filling the filler 5 (for example, non-shrink mortar) into the connection holes 21 provided at various places at the top end of the U-shaped block 2 and then closing the lid. When the block 3 is put on, the embedded bolt 33 provided on the back surface of the lid block 3 is fitted into the connection hole 21 and solidified and integrated. With this method, there is no displacement of the lid and no noise is generated due to backlash.
[0016]
Next, FIG. 3 shows an example of a lid block 3 'with a management hole provided with a management hole 34 for inspection and the like in the transverse groove. The management hole 34 is sufficiently larger than the upper and lower through holes 32 for collecting water, and has a length of 400 × 500 mm in this example. The management hole 34 is covered with the grating 41. The lid block 3 'with a management hole is to be installed in some places of the block continuously provided in the cross direction of the road.
