JP6327675B2 - U-shaped side gutter for lid for precast concrete street asphalt paving on apron - Google Patents

Description

  The present invention relates to a street-covering lid U-shaped side groove which is used for a roadway side belt of a paved road and forms a lid upper surface L-shaped drainage apron for traveling on an asphalt pavement.

  In conventional precast concrete side grooves, the upper surface of the lid is exposed on the shoulder of the road, making it difficult to draw the lane markings. The concrete surface remains along the asphalt pavement of the roadway and extends in a strip shape parallel to the road shoulder. Safety is a problem for roadside bicycle traveling across the upper surface and the shoulder pavement surface.

The kamaboko-shaped section of the roadway is in contact with the street with a cross slope of approximately 2%.
Recently, there is a growing need to use sideways on the roadway for bicycle driving. However, the “Guidelines for Creating a Safe and Comfortable Bicycle Use Environment” shown by the Japanese government specifies that the crossing slope of the apron with the side gutter is 2%. Asphalt pavement as a whole is required along with alleviating sudden changes from the roadway.

Problems to be solved by the invention

In the conventional gutter cover, the entire upper surface is exposed and occupies a part of the roadside belt, and the road edge is a different road surface from the asphalt pavement on the shoulder of the roadway. In the invention, the exposure is reduced to increase safety.
In the street block structure with L-shaped blocks, while maintaining the basic structure with the asphalt main pavement stop at the side edge of the roadway, it is possible to cycle by changing the crossing slope in combination with the asphalt top pavement including the apron surface. To fit.

Means for solving the problem

In order to solve the above-mentioned problem, the side groove of the present invention uses a lid with a curbstone, and a lid U-shaped side groove also serving as an asphalt main pavement stop or an upper lid U-shaped side groove on the lid plate serving as the asphalt main pavement stop is formed on an L-shaped apron street. The top apron of the cover plate is cut down to have a step, the cut down surface is covered with asphalt apron pavement, and the top pavement stopper is made of apron bottom.
In the construction of the road side belt for bicycle driving, the top surface that continues from the roadway to the pavement stop near the bottom of the apron is made asphalt pavement.

The apron pavement extends the upper pavement of the roadway as it is, covers the side groove upper surface, and continuously forms an apron street L-shaped slope to the pavement stop of the step.
When the crossing slope is 2%, which is equivalent to the roadway, it meets the safety guidelines for bicycle roads, and the road shoulder is a high safety road.

The upper surface of the step is the apron street bottom, and the curb is installed along the boundary of the walking road to become the apron street for paved roads.
In the case of drainage pavement with permeable asphalt on the upper surface of the roadway, the top pavement stop of the apron becomes the permeable asphalt edge and drains the permeated water along the street bottom to the U-shaped side gutter.

Effect of the invention

  The apron surface, excluding the bottom of the heel, is continuous with the apron pavement that is an extension of the pavement upper surface pavement. A roadside belt is formed.

  The apron crossing gradient is formed at 2%, which does not change suddenly from the roadway, and the roadside pavement surface spreads evenly, increasing the safety of cycling.

  When the upper pavement is made water permeable, the permeated water is discharged from the joint gap of each lid plate or the drop opening along the upper pavement stop that becomes the terminal of the apron pavement, thereby improving the effect of the water permeable pavement.

  The U-shaped side gutter main body according to the present invention is suitable for measures against deterioration in cold regions by being buried underground, and contributes to the maintenance of roads and the improvement of the service life.

  It is a notch slope view which shows the Example of the lid-hanging U-shaped side groove which uses the drop cover with a curb and makes the upper surface L-shaped apron street.   It is a notch slope view which shows the Example of the lid-hanging U-shaped side groove which uses a top cover with a curb and makes it an upper surface L-shaped apron street.   It is sectional drawing along the AA line of FIG.   It is sectional drawing along the BB line of FIG.   It is a slope view of the falling lid with a curb in the embodiment of FIG.   It is a slope view of the top cover with a curb in the example of FIG.   It is a perspective view which shows the other Example corresponding to the bearing surface with the gutter body of the drop lid with a curbstone.

The U-shaped side groove is supplied by precast concrete whose water cross section is generally 30cm to 40cm in the upper part of the inner width, 30 to 120cm in the inner height increment of 10cm, 1m and 2m in length, etc. The pavement thickness descending from the road surface is set to the top end height, and the upper cover side groove is laid from the road surface to the top plate thickness descending as the top end height.
The top cover plate is supplied with precast concrete with curb with a thickness of 9 cm to 12 cm and a length of 0.5 m, 0.6 m, 1 m, 2 m, etc., and is dropped on the gutter body and installed as a lid or top cover.

As a side ditch for a roadway side belt on a paved road, a cover with curb is used along the boundary between the roadway and the sidewalk, and the apron street is on the cover plate.
The top of the top apron is formed to match the conditions of a bicycle road with a 5cm step and a 2% crossing gradient with the apron slope as the apron slope and the asphalt pavement thickness as the apron slope. The bottom surface has a width of 5 cm to 10 cm.

  The level difference between the bottom of the lid and the cut-down apron is an asphalt top pavement stop. When the top pavement is made permeable, the permeated water is drained along the top pave stop serving as a terminal of the apron pavement.

  The curbstones are 15cm, 20cm, and 25cm in height from the bottom of the basin, and are installed on the sidewalk side of the cover plate with the sidewalk surface and mound-up or flat or semi-flat formation.
