Embodiment 1

[0029] see Figure 1 ~ Figure 2 , this embodiment discloses a drainage curbstone, the drainage curbstone 100 is provided with a cavity 110 extending along the length direction of the drainage curbstone 100, and the cavity 110 runs through the drainage curbstone 100 for Drainage: the drainage curbstone 100 is also provided with a water inlet chamber 120 perpendicular to the length direction of the drainage curbstone 100, the lowest surface of the entrance of the water inlet chamber 120 is not higher than the road surface 10, and the outlet of the water inlet chamber 120 communicate with the groove cavity 110, and are used to introduce accumulated water on the road surface 10 into the groove cavity 110, and the water flow direction on the road surface 10 is as follows: figure 1 indicated by the middle arrow.

[0030] The present invention is applicable to various types of curbstones, that is, for various types of curbstones, it can be realized by setting the groove cavity 110 a...

Embodiment 2

[0036] see image 3 , this embodiment also discloses a drainage curbstone, the drainage curbstone in this embodiment is a further improvement on the basis of the first embodiment, the technical solution disclosed in the first embodiment also belongs to this embodiment, and the first embodiment has The disclosed technical solutions will not be described repeatedly.

[0037]Specifically, this embodiment improves the cavity 110 in the first embodiment, that is, further improves the cavity shape of the cavity 110 . The elliptical shape in Embodiment 1 has a relatively better drainage effect, but the casting mold of the narrow and deep elliptical cavity 110 is relatively complicated, and the water depth in the cavity 110 is generally less than half of the groove depth during specific operations. Based on this, this embodiment improves the cavity shape of the upper half of the groove cavity 110, and sets the cavity shape of the upper half part as a wide and shallow semi-ellipse, so...

Embodiment 3

[0040] see Figure 4 , this embodiment also discloses a drainage curb, the drainage curb of this embodiment is a further improvement on the basis of the second embodiment, the technical solution disclosed in the second embodiment also belongs to this embodiment, and the second embodiment has The disclosed technical solutions will not be described repeatedly.

[0041] Specifically, this embodiment is a further improvement on the cavity shape of the cavity 110 in the second embodiment. The cavity 110 in the second embodiment has a better drainage effect and low casting cost. On the basis of this embodiment, the upper semi-ellipse in the second embodiment is further improved to increase its Load capacity.

[0042] see Figure 4 , the cavity shape of the groove cavity 110 is formed by smoothly connecting two sections of arcs, the arc located at the bottom is a semi-ellipse with an upward opening, the arc located at the top is conical, and the expansion mouth of the taper is dow...

Abstract

The invention discloses a drainage curbstone. A groove chamber extending in the length direction of the curbstone is arranged in the curbstone; the groove chamber penetrates through the curbstone and is used for drainage; the curbstone is also provided with a water inlet cylinder chamber which is perpendicular to the length direction of the curbstone; the lowest surface of the inlet of the water inlet cylinder chamber is not higher than the road surface; the outlet of the water inlet cylinder chamber is communicated with the groove chamber; and the water inlet cylinder chamber is used for introducing water accumulated on the road surface into the groove chamber. The drainage curbstone increases the water collection area and water collection quantity, can supplement the water collection quantity of the existing gutter inlet, conforms to the latest national drainage standard in which the drainage reoccurrence period is converted from 1 year to 3-5 years, and improves the following technical problems in the existing drainage method simply dependent on the road surface gutter inlets: the gutter inlets can be easily blocked, the grates can be easily pilfered, the road surface can be easily destroyed and the like.

Description

technical field [0001] The invention relates to the field of road infrastructure, in particular to a road curb with drainage function. Background technique [0002] Road drainage is closely related to everyone, and it is another notable feature of an international metropolis. If drainage is not timely or the drainage method is chosen incorrectly, it will bring unnecessary troubles to the society and the people. Such as wet trouser legs when walking, mud splashed by a car, etc. [0003] The existing drainage method is to divert the runoff water from the road radially along the curb and collect it at the rainwater outlet, and lead it into the sewer through the rainwater outlet to achieve the purpose of drainage. The radial direction refers to the direction perpendicular to the length of the road. Existing drainage methods have at least the following defects: [0004] First, in order to ensure the flatness and strength of the road surface as much as possible, the number of gu...
