DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0026] First embodiment:

[0027] like Figure 1-6 As shown, the road anti-blocking drainage device provided by the utility model includes: a filter mechanism 100 and a drainage mechanism 200. The filter mechanism 100 is located at the upper end of the drainage mechanism 200. The function of the filter mechanism 100 is to block impurities in the rainwater flowing into the drainage mechanism 200 to prevent the impurities in the rainwater from clogging the drainage mechanism 200. Specifically, the filter mechanism 100 includes a curb 101, and a cover plate 102 is fixedly provided on one side of the curb 101. The cover plate 102 is U-shaped. This part can be molded by using a model and concrete as a whole, such as Figure 2 As shown in , the curbstone 101 and the drainage ditch 203 are made into a unified whole. During construction, the curbstone 101 is installed and the road surface drainage channel is excavated simultaneously. A drainage ditch 203 is provided just below the cover plate 102. The drainage ditch 203 is also U-shaped and prefabricated with concrete. A plurality of holes 103 are provided on one side of the drainage ditch 203. The holes 103 can be made into a circle for drainage. It should be noted that the lower end of the hole 103 is kept tangent to the road surface 300 during burial. A detachable filter assembly is provided in the hole 103. The filter assembly is installed in the hole 103 and can be drawn out. The filter assembly includes a fixing ring 106, which is made of a stainless steel pipe. The first filter screen 105 is installed on the fixing ring 106. The fixing ring 106 is provided with a handle 107, through which the filter assembly can be easily taken out from the hole 103. A retaining net 111 can also be movably provided at the opening of the hole 103 of the curb 101. During construction, a ditch for drainage of the road surface 300 is first excavated according to the size of the drainage ditch 203, and then the drainage ditch 203 and other related components are installed in the ditch, and the cover plate 102 is covered, and finally multiple device units are connected.

[0028] The drainage effect of the road surface 300 is achieved by setting the drainage groove 203. Compared with the method of setting the drainage holes horizontally on the road surface 300 in the prior art, the holes 103 for drainage of the road surface 300 are set on the side wall of the curb 101, which is a vertical arrangement. Impurities such as fallen leaves on the road surface 300 float on the water surface under the buoyancy of water. When the fallen leaves gather at the hole 103 with the water flow, the lower end of the hole 103 can still pass water, so the possibility of being blocked is relatively small.

[0029] In addition, the curbstone 101 and the drainage trough 203 are integrated into a unified device and spliced ​​in a prefabricated manner to speed up the construction progress.

[0030] Second embodiment:

[0031] like Figure 4 , Figure 6 As shown, a first protrusion 104 is provided at the lower end of the cover plate 102, and a first groove 201 is provided at the upper end of the drainage groove 203. The first protrusion 104 fits with the first groove 201, and a rubber pad 205 is provided between the first protrusion 104 and the first groove 201. The first protrusion 104 and the first groove 201 can be made using a template during prefabrication, and a model shape having the same shape as the first protrusion 104 and the first groove 201 is set at the relative position of the cast-in-place template device, and the first protrusion 104 and the first groove 201 are generated after casting and demolding.

[0032] By providing the first protrusion 104 and the first groove 201 that fit each other, the connection stability between the cover plate 102 and the drainage groove 203 is made higher. At the same time, the connection sealing performance between the cover plate 102 and the drainage groove 203 can be improved by the rubber pad 205 to prevent water from seeping out from the connection seam between the two.

[0033] Third embodiment:

[0034] like Figure 2-3 As shown, an opening is provided at the upper end of the cover plate 102, and a filter plate 108 can be detachably installed at the opening. A plurality of small circular holes are provided on the surface of the filter plate 108, and the circular holes are used for drainage. A second filter screen 109 is provided at the lower end of the filter plate 108. When the rainfall is heavy, water overflows the upper edge of the curb 101 and enters the filter plate 108 at the upper end of the cover plate 102, and then enters the drainage trough 203 through the small circular holes.

[0035] The filter plate 108 can be provided as a second line of defense for drainage. That is, when the rainfall is large and exceeds the drainage capacity of the holes 103 on the surface of the curb 101, the water can be intercepted by the cover plate 102, and the second filter screen 109 can retain impurities that enter the second filter screen 109 through the circular holes. After the rain, the second filter screen 109 can be taken out and cleaned.

[0036] Fourth embodiment:

[0037] like Figure 2 As shown, a lace 110 is provided on the upper end of the curb 101. The lace 110 is composed of a number of arc-shaped block units. When the rainfall is heavy, the water overflows the upper surface of the curb 101, which may cause pedestrians or vehicles to lose their judgment of the roadside position, which may easily cause danger. The lace 110 is higher than the upper surface of the curb 101. When the curb 101 is submerged in water, the lace 110 can be used as a warning sign to indicate the roadside position of pedestrians or vehicles, thereby improving safety.

[0038] Fifth embodiment:

[0039] like Figure 5-6 As shown, a second protrusion 204 is provided at one end of the drainage groove 203, and a second groove 202 is provided at the other end. The device is prefabricated and assembled. A gap will be generated at the connection between two adjacent drainage grooves 203. The function of the drainage groove 203 is to drain water, and water seeps into the ground from the gap. The connection sealing of the two adjacent drainage grooves 203 can be improved by setting the second protrusion 204 and the groove 202. In order to further improve the waterproof performance, waterproof membrane is laid at the connection seam during construction.

[0040] Working principle: The curbstone 101 and the drainage ditch 203 are made into a unified whole by integrally pouring concrete. During construction, the curbstone 101 and the excavated road surface 300 are drained simultaneously. During construction, first, a ditch for drainage of the road surface 300 is excavated according to the size of the drainage ditch 203, and then the drainage ditch 203 and other related components are installed in the ditch, covered with a cover plate 102, and finally multiple device units are connected. The holes 103 for drainage of the road surface 300 are set on the side wall of the curbstone 101, which is a vertical arrangement. Impurities such as fallen leaves on the road surface 300 float on the water surface under the buoyancy of water. When the fallen leaves gather at the mouth of the hole 103 with the water flow, the lower end of the hole 103 can still pass water, so the possibility of being blocked is small.

[0041] The above embodiment is only one of the preferred implementation modes of the present utility model and should not be used to limit the protection scope of the present utility model. Any changes or modifications that are made to the main design concept and spirit of the present utility model without any substantive significance, as long as the technical problems solved are still consistent with the present utility model, should be included in the protection scope of the present utility model.
