Description

Technical Field

[0001] This utility model relates to the field of road drainage technology, specifically to a prefabricated drainage curb and drainage system. Background Technology

[0002] Currently, road stormwater drainage mainly relies on two methods: point drainage and linear drainage ditches. Point drainage requires the installation of individual stormwater wells every 20-30 meters along the roadside. Stormwater must collect over long distances along the road's cross and longitudinal slopes or zigzag ditches, resulting in low water collection efficiency and the potential for flooding even with minor blockages. While linear drainage ditches employ a continuous trench design and have a water collection efficiency 3-5 times higher than point systems, vehicle traffic can cause vibrations and noise to the ditch covers, leading to loosening or damage. Furthermore, linear drainage ditches are difficult to install in areas with dense municipal pipelines due to space constraints. Utility Model Content

[0003] The purpose of this utility model is to provide a prefabricated drainage curbstone and drainage system. It can drain water by opening a hollow drainage cavity in the curbstone body and opening drainage holes on the side of the curbstone body, while cooperating with rigid permeable pipes. This not only saves the installation space and avoids the space restrictions of municipal pipeline installation, but also effectively improves the efficiency of rainwater collection and drainage, reduces road runoff, and the curbstone is economical, easy to construct, and not easily damaged. At the same time, it will not be run over by vehicles and will not affect the driving experience and driving safety.

[0004] To achieve the above objectives, according to a first aspect of this utility model, a prefabricated drainage curbstone is provided, comprising:

[0005] The side stone body has a hollow drainage cavity defined within it, and a plurality of drainage holes communicating with the hollow drainage cavity are spaced apart along the length of the side stone body on the side facing the road.

[0007] Optionally, the hollow drainage cavity is provided with a filter screen along its inner circumference to intercept large-volume debris in rainwater.

[0008] Optionally, the rigid permeable pipe is covered with a permeable geotextile to filter impurities in rainwater.

[0009] Optionally, the rigid permeable pipe is provided with multiple permeable holes along its length, and the multiple permeable holes cooperate to perform multi-point drainage.

[0011] The precast drainage curb stones are installed on both sides of the road;

[0012] Rainwater wells are installed on both sides of the road and connected to the rigid permeable pipes inside the precast drainage curbs;

[0013] Rainwater branch pipes are installed between the rainwater wells on both sides of the road and are connected to the corresponding rainwater wells;

[0014] The municipal drainage network is connected to the aforementioned rainwater branch pipe;

[0015] The precast drainage curbstone, the rainwater well, and the rainwater branch pipe work together to collect rainwater and discharge it into the municipal drainage network.

[0016] The beneficial effects of this utility model are as follows: by opening a hollow drainage cavity in the main body of the curbstone and opening drainage holes on the side of the main body of the curbstone, and cooperating with a rigid permeable pipe for drainage, it not only saves the layout space and avoids the space restriction of municipal pipeline layout, but also effectively improves the efficiency of rainwater collection and drainage, reduces road runoff, and the curbstone is economical in cost, easy to construct, not easy to be damaged, and will not be run over by vehicles, so as not to affect the driving experience and driving safety.

[0022] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] Please see Figure 1 and Figure 2 A preferred embodiment of this application shows a prefabricated drainage curbstone including a curbstone body 1 and a rigid permeable pipe 2. A hollow drainage cavity 3 is defined within the curbstone body 1, and a plurality of drainage holes 4 communicating with the hollow drainage cavity 3 are spaced apart along the length of the curbstone body 1 on the side facing the road. The rigid permeable pipe 2 is disposed within the hollow drainage cavity 3 and is used to cooperate with the curbstone body 1 for drainage.

[0026] According to the embodiment of this utility model, by opening a hollow drainage cavity 3 in the side stone body 1 and opening a drainage hole 4 on the side of the side stone body 1, and cooperating with a rigid permeable pipe 2 for drainage, not only is the layout space saved and the space restriction of municipal pipeline layout avoided, but the rainwater collection and drainage efficiency is also effectively improved, the road runoff is reduced, and the side stone is economical, easy to construct, and not easily damaged. At the same time, it will not be run over by vehicles and will not affect the driving experience and driving safety.

[0027] The following detailed description uses specific examples:

[0028] Further, please see Figure 1 and Figure 2 The hollow drainage cavity 3 is equipped with a filter screen 5 along its inner circumference to intercept large-volume debris in rainwater. This design intercepts and collects large-volume debris and contaminants before rainwater enters the rigid permeable pipe 2, effectively preventing foreign objects such as fallen leaves and plastic bags from clogging the pipe and reducing the frequency of routine maintenance. Specifically, in this embodiment, the side stone body 1 is precast using C35 cement concrete, with dimensions of 100*20*35cm. The longitudinal cross-sectional dimensions of the hollow drainage cavity 3 are 15*25cm. The rigid permeable pipe 2 is... 2. PE rigid permeable pipe.

[0029] Further, please see Figure 1 The rigid permeable pipe 2 is covered with a permeable geotextile 6 on the outside to filter impurities in rainwater. The permeable geotextile 6 further filters fine impurities in rainwater, prevents fine sand and silt from entering the rigid permeable pipe 2, keeps the pipe network unobstructed, and extends the service life of the system.

[0030] Specifically, the rigid permeable pipe 2 has multiple permeable holes along its length, which work together to provide multi-point drainage. The multiple permeable holes are distributed at different locations on the rigid permeable pipe 2, which can more evenly distribute rainwater flow, thereby avoiding localized water accumulation or excessive pipe pressure caused by concentrated water flow. At the same time, the multiple permeable holes also increase the flow rate of rainwater, preventing siltation and blockage problems caused by prolonged water accumulation.

[0031] Please see Figure 3 This utility model embodiment also provides a drainage system, including prefabricated drainage curb stones 10, rainwater wells 20, rainwater branch pipes 30, and a municipal drainage network 40. The prefabricated drainage curb stones 10 are installed on both sides of the road, and the rainwater wells 20 are installed on both sides of the road and connected to the rigid permeable pipes 2 within the prefabricated drainage curb stones 10. The rainwater branch pipes 30 are installed between the rainwater wells 20 on both sides of the road and connected to the corresponding rainwater wells 20. The municipal drainage network 40 is connected to the rainwater branch pipes 30. The prefabricated drainage curb stones 10, rainwater wells 20, and rainwater branch pipes 30 cooperate to collect rainwater and discharge it into the municipal drainage network 40.

[0032] During drainage, rainwater first flows along the road cross slope into the drainage holes 4 on the side of the curbstone body 1, enters the hollow drainage cavity 3 inside the curbstone body 1, and after being intercepted by the internal filter screen 5, large-volume garbage is filtered through the permeable geotextile 6 covering the rigid permeable pipe for secondary filtration of fine impurities. Then, it is collected along the longitudinal slope through the rigid permeable pipe to the rainwater well 20, and then discharged into the municipal drainage network 40 through the transverse rainwater branch pipe 30. The whole process does not require excavation of trenches or installation of covers, which improves drainage efficiency and reduces maintenance costs and traffic interference.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
