Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of road drainage, in particular to a road drainage structure. Background Art
[0002] The current paving design of urban roads generally adopts a horizontal slope with a slightly convex center and gradually lower sides. This design is intended to optimize rainwater discharge and ensure that rainwater can flow smoothly along the road surface to both sides of the road and merge into the drainage system. However, in the case of heavy rain or a large amount of garbage and sand and gravel accumulation in specific areas of the road surface, rainwater not only accelerates the scouring of these debris, but also may carry them through the leaky grooves set on the road surface and eventually enter the entrance of the drainage pipe. These garbage, debris and sand and gravel carried by rainwater are often difficult to be discharged smoothly in the drainage pipe, and are easy to accumulate at the entrance of the drainage pipe, thereby reducing the drainage capacity of the area. In extreme cases, it may even cause partial blockage of the drainage pipe; since the drainage pipe is a fully connected network system, once a blockage occurs somewhere, its impact will quickly spread to the entire drainage pipe, resulting in a significant reduction in the overall drainage efficiency, a slowdown in drainage speed, and even possible waterlogging problems.
[0003] Therefore, in view of this, the inventor proposes a road drainage structure to solve the above technical problems. Utility Model Content
[0004] The utility model aims to provide a road drainage structure to solve the problem that the inlet of the existing drainage pipe is easily blocked, thereby causing waterlogging.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0006] A road drainage structure is used to be installed on both sides of a road, comprising drainage sections arranged at intervals along the length direction of the road and grooves arranged between the drainage sections;
[0007] Water inlets connected to the groove are provided at both ends of the drainage section, a main drainage outlet and secondary drainage outlets are provided at the bottom of the drainage section, and the two secondary drainage outlets are respectively located on both sides of the main drainage outlet;
[0008] Filters are arranged above the main drain outlet and the two secondary drain outlets; and drain pipes are connected below the main drain outlet and the two secondary drain outlets.
[0009] According to the above technical solution, when rainwater enters the ditch along the road, the rainwater flows through the ditch to the drainage node, and first enters through the water inlets at both ends of the drainage node. After entering the drainage node, the rainwater will first encounter the filter element arranged above the main drainage outlet and the secondary drainage outlets on both sides. The filter element can effectively intercept larger particles of debris carried in the rainwater, such as leaves, plastic bags, sand and stones, to prevent them from entering the drain pipe.
[0010] The rainwater that has been initially filtered then flows into the drain pipe below through the main drain outlet and the secondary drain outlets on both sides. This diversion design not only increases the drainage area and improves drainage efficiency, but also makes the water flow more evenly distributed in the pipe, reducing the risk of local blockage.
[0011] Furthermore, the filter element comprises a main filter tank and secondary filter plates, the main filter tank is arranged inside the drainage section, and the main filter tank is arranged above the main drainage port;
[0012] The secondary filter plate is fixed inside the drainage section, and the secondary filter plate covers the top of one of the secondary drainage ports.
[0013] According to the above technical solution, rainwater flows from the road groove into the drainage section, and first contacts the inclined secondary filter plate, which can initially intercept larger debris carried in the rainwater, such as leaves, plastic bags, etc., and the debris enters the main filter tank. The debris initially filtered and guided by the secondary filter plate will eventually fall into the main filter tank, which is located inside the drainage section and above the main drainage port, for receiving the debris guided by the secondary filter plate and further filtering the remaining tiny particles in the rainwater. The main filter tank can ensure that only clean rainwater can pass through and enter the drainage pipe below. At the same time, the main filter tank also plays the role of collecting and temporarily storing debris, waiting for subsequent cleaning and maintenance.
[0014] Furthermore, the main filter tank includes a bottom plate and four side plates, the four side plates are enclosed together to form a frame structure, and the bottom plate is fixedly arranged at the bottom of the frame structure;
[0015] The frame structure and the bottom plate are both provided with leakage holes.
[0016] The main filter tank is a frame structure formed by the bottom plate and four side plates, which provides a space for rainwater to settle and filter. There are holes on the bottom plate and the four side plates of the frame structure, and larger debris and particles are intercepted in the main filter tank. As the rainwater continues to flow in, these debris will gradually settle on the bottom plate or be washed to the corners of the filter tank.
[0017] Furthermore, the middle portion of the bottom plate bulges upward to form a raised portion, and the raised portion has a conical structure.
[0018] According to the above technical solution, the conical structure has a natural guiding property, which is beneficial to the anti-clogging effect. When rainwater enters the main filter tank, the conical protrusion can guide the water flow along its surface to form a certain water flow path. This guiding effect helps to reduce the retention time of water flow in the main filter tank and reduce the risk of debris deposition.
[0019] Furthermore, the two secondary filter plates are both arranged at an incline.
[0020] According to the above technical solution, the secondary filter plate is set at an angle, and the intercepted debris will slide along the secondary filter plate to the main filter tank under the action of gravity and water flow, which is convenient for subsequent cleaning.
[0021] Furthermore, the drainage pipe includes a first pipe and two second pipes, the first pipe is connected to the main drainage outlet, and the other end of the first pipe is used to connect to the municipal water pipe; one end of the second pipe is connected to one of the secondary drainage outlets, and the other end of the second pipe is connected to the first pipe.
[0022] Furthermore, the main filter tank is detachable.
[0023] According to the above technical solution, the detachable design makes the replacement of the main filter tank simple and quick. When the debris in the filter tank accumulates to a certain extent and affects the filtering effect, the main filter tank can be easily taken out for cleaning or replacement without complicated operations or professional tools.
[0024] Furthermore, the groove includes a plurality of bases connected end to end, and the cross section of the base is a concave structure.
[0025] Furthermore, a sealing tape is provided between two adjacent bases and between a base and the drainage joint.
[0026] According to the above technical solution, by tightly fitting the gaps between two adjacent bases and between the base and the drainage node, the sealing tape can effectively prevent rainwater, sewage or other liquids from leaking through these gaps, thereby helping to maintain the integrity and stability of the drainage system.
[0027] Furthermore, a floor drain cover is detachably provided on the top of the drainage joint and the base.
[0028] Beneficial effects of the utility model:
[0029] The utility model forms an efficient drainage network by setting a plurality of end-to-end connected bases and drainage nodes arranged at intervals along the length of the road. Rainwater can quickly flow into the drainage node through the groove, and enter the drainage pipe through the main drainage port and the secondary drainage ports on both sides. This diversion design not only increases the drainage area, but also makes the water flow more evenly distributed in the pipe, thereby significantly improving the drainage efficiency; at the same time, a filter element (including a main filter tank and a secondary filter plate) is set inside the drainage node to effectively intercept larger particles of debris carried in the rainwater, such as leaves, plastic bags, sand and stones, to prevent them from entering the drainage pipe and causing blockage. The inclined setting of the filter element and the design of the conical protrusion further promote the accumulation and cleaning of debris and reduce the risk of blockage.
[0030] The drainage structure adopts a detachable floor drain cover, main filter tank and other designs, making the maintenance and cleaning of the system simple and quick. When the debris in the floor drain cover or main filter tank accumulates to a certain extent, it can be easily removed, cleaned or replaced, which not only reduces maintenance costs, but also improves maintenance efficiency, ensuring the long-term stable operation of the drainage system.

DETAILED DESCRIPTION
[0039] The following will describe the implementation of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.
[0040] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.
[0041] This embodiment provides a road drainage structure for installation on both sides of the road. Figures 1 to 6 As shown, it includes drainage nodes 2 arranged at intervals along the length direction of the road 1 and grooves 3 arranged between the drainage nodes 2; the groove 3 includes a plurality of bases 31 connected end to end, and the cross section of the base 31 is a concave structure. In this embodiment, five bases 31 are arranged between adjacent drainage nodes 2, and the tops of the drainage nodes 2 and the bases 31 are detachably provided with floor drain covers 7.
[0042] Water inlets 23 connected to the groove 3 are provided at both ends of the drainage section 2. A main drainage outlet 21 and secondary drainage outlets 22 are provided at the bottom of the drainage section 2. The secondary drainage outlets 22 are respectively located on both sides of the main drainage outlet 21. Filters 4 are arranged above the main drainage outlet 21 and the secondary drainage outlets 22. Drain pipes 5 are connected below the main drainage outlet 21 and the secondary drainage outlets 22. When rainwater enters the groove 3 along the road 1, it flows from the water inlet 23 to the drainage section 2 through the groove 3, and first enters through the water inlets 23 at both ends of the drainage section 2. After entering the drainage section 2, the rainwater first encounters the filters 4 arranged above the main drainage outlet 21 and the secondary drainage outlets 22 on both sides. The filters 4 can effectively intercept larger particles of debris carried in the rainwater, such as leaves, plastic bags, sand and stones, to prevent them from entering the drainage pipe 5. The filtered rainwater then flows into the drain pipe 5 below through the main drain outlet 21 and the secondary drain outlets 22 on both sides. This diversion design not only increases the drainage area and improves the drainage efficiency, but also makes the water flow more evenly distributed in the pipe, reducing the risk of local blockage.
[0043] Furthermore, the filter element 4 includes a main filter tank 41 and secondary filter plates 42. The main filter tank 41 is arranged inside the drainage section 2, and the main filter tank 41 is arranged above the main drainage port 21; the secondary filter plate 42 is fixed inside the drainage section 2, and the secondary filter plate 42 covers the secondary drainage port 22, and the two filter plates 42 are both arranged at an angle.
[0044] Rainwater flows from the groove 3 of the road 1 into the drainage node 2, and first contacts the inclined secondary filter plate 42. The secondary filter plate 42 is inclined, and the intercepted debris will slide along the secondary filter plate 42 to the main filter tank 41 under the action of gravity and water flow, which is convenient for subsequent cleaning. The main filter tank 41 also plays the role of collecting and temporarily storing debris, waiting for subsequent cleaning and maintenance.
[0045] As a preferred embodiment, the main filter tank 41 includes a bottom plate 411 and four side plates 412. The four side plates 412 are enclosed together to form a frame structure. The bottom plate 411 is fixedly arranged at the bottom of the frame structure. The frame structure and the bottom plate 411 are both provided with leakage holes. The main filter tank 41 is enclosed by the bottom plate 411 and the four side plates 412 to form a frame structure, which provides a storage space for rainwater and allows rainwater to be initially precipitated and filtered therein. Leakage holes are provided on the bottom plate 411 and the four side plates 412 of the frame structure, and larger debris and particles are intercepted in the main filter tank 41. As the rainwater continues to flow in, these debris will gradually settle on the bottom plate 411 or be washed to the corners of the main filter tank 41.
[0046] As a preferred embodiment, the middle of the bottom plate 411 bulges upward to form a raised portion 413, and the raised portion 413 is a conical structure; the conical structure has a natural guiding property, which is conducive to anti-clogging. When rainwater enters the main filter tank 41, the conical raised portion 413 can guide the water flow along its surface to form a certain water flow path. This guiding effect helps to reduce the retention time of the water flow in the main filter tank 41 and reduce the risk of debris deposition.
[0047] Furthermore, the drainage pipe 5 includes a first pipe 51 and two second pipes 52. The first pipe 51 is connected to the main drainage port 21, and the other end of the first pipe 51 is used to connect to the municipal water pipe; one end of the second pipe 52 is connected to one of the secondary drainage ports 22, and the other end of the second pipe 52 is connected to the first pipe 51. The design of the first pipe 51 and the second pipe 52 enables the system to improve the drainage path and flow distribution to avoid waterlogging.
[0048] Furthermore, the main filter tank 41 is detachable. The detachable design makes the replacement of the main filter tank 41 simple and quick. When the debris in the main filter tank 41 accumulates to a certain extent or affects the filtering effect, the main filter tank 41 can be easily taken out for cleaning or replacement without complicated operations or professional tools.
[0049] Furthermore, a sealing tape 6 is provided between two adjacent bases 31 and between the base 31 and the drainage node 2. According to the above technical solution, by closely fitting the gap between the two adjacent bases 31 and between the base 31 and the drainage node 2, the sealing tape 6 can effectively prevent rainwater from leaking from these gaps, which helps to maintain the integrity and stability of the drainage system.
[0050] The utility model forms an efficient drainage network by setting a plurality of end-to-end bases 31 and drainage nodes 2 arranged at intervals along the length direction of the road 1. Rainwater can quickly flow into the drainage node 2 through the groove 3, and enter the drainage pipe 5 through the main drainage port 21 and the secondary drainage ports 22 on both sides. This diversion design not only increases the drainage area, but also makes the water flow more evenly distributed in the pipeline, thereby significantly improving the drainage efficiency; at the same time, a filter 4 (including a main filter tank 41 and a secondary filter plate 42) is set inside the drainage node 2 to effectively intercept larger particles of debris carried in the rainwater, such as leaves, plastic bags, sand and stones, etc., to prevent them from entering the drainage pipe 5 and causing blockage. The inclined setting of the filter 4 and the design of the conical protrusion 413 further promote the accumulation and cleaning of debris and reduce the risk of blockage.
[0051] The drainage structure adopts a detachable floor drain cover 7, main filter tank 41 and other designs, making the maintenance and cleaning of the system simple and quick. When the debris in the floor drain cover 7 or the main filter tank 41 accumulates to a certain extent, it can be easily disassembled, cleaned or replaced, which not only reduces the maintenance cost but also improves the maintenance efficiency, ensures the long-term stable operation of the drainage system, and solves the problem that the entrance of the existing drainage pipe is easily blocked, thereby causing waterlogging.
[0052] The above embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Any equivalent substitution or modification made by a person skilled in the art based on the present invention is within the protection scope of the present invention.
