Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a drainage basin for, for example, a bridge or a viaduct.

[0002]

2. Description of the Related Art FIG. 6 is a sectional view showing a conventional bridge drainage basin. This bridge drainage basin is composed of a basin body 61 made of, for example, FRP and a grating 62. The FRP basin main body 61 is a box body having an upper opening and a bottom, and a drainage tube 63 is integrally protruded from a bottom portion on one end side. A support portion 64 is provided on the periphery of the upper opening side of the box body 61, and the fitting grating 62 is supported by the support portion 64.

The upper surface A of a pavement such as a bridge or viaduct has a slight slope. For this reason, in the conventional drainage basin, the upper opening (supporting portion 64) itself of the basin main body 61 is specified and formed at a predetermined slope, and the fitting grating 62 is formed on the pavement upper surface A.
Is set to correspond to the gradient of.

[0004]

The slope of the upper surface of a pavement road of a bridge or viaduct varies depending on the pavement road (for example, the gradient ranges from 2% to 6%). On the other hand, in the conventional drainage basin, the gradient of the basin itself is specified, and it cannot cope with various unspecified road surface gradients. For this reason, conventionally, there was a disadvantage that a plurality of types of drainage basins had to be manufactured and stocked.

The conventional grating has a structure in which the grating is simply fitted into the upper opening of the main body of the box. That is, the structure is only supported by the support portion. For this reason, when the vehicle passes over the grating, there is a disadvantage that an accident occurs in which the grating blows outward from the box body, which is dangerous.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, makes it possible to easily adjust and cope with various inclinations of the upper surface of a pavement road, and eliminates the danger of a blow-off accident of grating and the like. I will provide a.

[0007]

In order to achieve this object, a drainage basin according to the present invention has the following configuration. The drainage basin is composed of a basin body with an upper opening having a drainage tube at an appropriate place at the bottom, and a grating fitted and fitted to the basin body. It is characterized in that the height adjustment means are arranged at regular intervals and each height adjustment means is adjusted in height so that the grating corresponds to the gradient of the upper surface of the pavement road.

In the drainage basin having such a configuration, the height adjusting means includes, for example, a bolt (adjustment shaft), a double nut (support portion), and a fixed nut (stopper portion).
For example, assuming that the slope of the upper surface of the pavement is 4% inclined with respect to the horizontal (a 4% gradient from one end to the other end in the longitudinal direction of the drainage basin), the double nut position of the bolt at one end is set high. , Set the double nut position of the bolt on the other end side low.

That is, by moving the adjustment shaft (bolt) up and down, one end of the grating (supported plate portion of the fitting frame) is supported high on the upper surface of the double nut at one end, and the other end of the grating is held at the other end. Support it low on the upper surface of the double nut at the other end. By performing this height adjustment, the grating (fitting frame) is set so as to have the same gradient as 4% of the upper surface of the pavement road as a whole.

Thus, by performing height adjustment of the height adjusting means in accordance with the gradient of the pavement road surface, the grating can be made to correspond to various gradients of the pavement road surface. Further, in this state, for example, the tip portions of the four bolts (upper portions above the double nut mounting position) are set to the same protruding length in advance. It penetrates through holes that communicate with the superposed plate part. Therefore, by fastening a nut (fastening member) to this penetrating tip, the grating is moved via the height adjusting means to the main body (fitting frame).
To be fixed.
