Description

Technical Field

[0001] This utility model relates to the field of concrete drainage ditch cover technology, and in particular to a concrete drainage ditch cover with water permeability. Background Technology

[0002] Concrete drainage ditch covers are drainage facility covers made of cement as the base material and reinforced with steel bars and other reinforcing materials through a specific process. With their excellent compressive strength and wear resistance, they can easily withstand vehicle traffic and long-term pedestrian foot traffic, effectively ensuring road safety.

[0003] The existing concrete drainage ditch covers lack a bottom water backflow prevention structure, and their functionality and practicality need to be improved. Utility Model Content

[0004] The purpose of this utility model is to provide a concrete drainage ditch cover with water permeability that can facilitate smooth drainage while preventing backflow of water, and has high surface permeability, making it highly functional and practical.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A permeable concrete ditch cover includes a concrete casting body, a receiving groove is provided on the lower surface of the concrete casting body, a floating plate is movably installed inside the receiving groove, a plurality of second drainage channels are provided on the outer surface of the floating plate, and a plurality of first drainage channels are provided on the outer surface of the concrete casting body, with the plurality of first drainage channels and the plurality of second drainage channels alternately distributed.

[0007] By adopting the above technical solution, smooth drainage operation can be carried out, while avoiding backflow of water. It is highly practical and functional.

[0008] Furthermore, the interior of the concrete casting body is provided with a steel reinforcement frame.

[0009] By adopting the above technical solutions, the overall structural strength of the drainage ditch cover can be effectively improved.

[0010] Furthermore, two connecting strips are fixedly connected to the outer surface of the steel keel, and multiple limiting rods are fixedly connected to the lower surface of the connecting strips, with one end of the limiting rods extending into the interior of the receiving groove.

[0011] By adopting the above technical solution, it is easier to install the subsequent anti-backflow structure.

[0012] Furthermore, multiple limiting sliding holes are provided at the edge of the float plate, and the limiting rod passes through the interior of the limiting sliding holes of the float plate. A limiting nut is installed on the external thread of one end of the limiting rod.

[0013] By adopting the above technical solution, the floating plate can be limited.

[0014] Furthermore, a limit connection groove is provided on the upper surface of the concrete casting.

[0015] By adopting the above technical solutions, an effective connection structure can be provided for permeable structures.

[0016] Furthermore, a permeable gravel layer is laid on the upper surface of the concrete casting body, and the permeable gravel layer fits into the interior of the limiting connection groove.

[0017] By adopting the above technical solutions, the permeability and anti-slip performance of the drainage ditch cover surface can be effectively improved.

[0018] In summary, the beneficial technical effects of this utility model are as follows:

[0019] 1. In use, the drainage ditch cover can be laid at a designated location. When water accumulates, it flows through the interior of the first and second drainage channels in sequence and is then discharged. If backflow occurs in a low-lying area, the float plate inside the collection trough can adhere to the inner end face of the collection trough under the action of buoyancy. Since the first and second drainage channels are alternately distributed, when the float plate adheres to the inner end face of the collection trough, it can effectively block the first drainage channel, thereby preventing backflow of water. The functionality and practicality are both effectively improved.

[0020] 2. This utility model sets a limiting connection groove on the upper surface of the concrete casting body, and lays a permeable gravel layer on the upper surface of the concrete casting body. The permeable gravel layer fits into the inside of the limiting connection groove. At this time, the permeable gravel layer can firmly adhere to the upper surface of the concrete casting body. The permeable gravel layer can be used to improve the water permeability of the entire ditch cover surface, and at the same time improve the anti-slip performance of the ditch cover surface, thereby improving the practicality and functionality of the entire ditch cover.

[0024] The method of this utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Reference Figure 1 , Figure 2 A permeable concrete ditch cover includes a concrete casting body 4, a receiving groove 10 on the lower surface of the concrete casting body 4, a floating plate 12 movably installed inside the receiving groove 10, multiple second drainage channels 9 on the outer surface of the floating plate 12, and multiple first drainage channels 8 on the outer surface of the concrete casting body 4, with the multiple first drainage channels 8 and multiple second drainage channels 9 alternately distributed. A steel reinforcement keel 1 is installed inside the concrete casting body 4, and two connecting strips 2 are fixedly connected to the outer surface of the steel reinforcement keel 1. Multiple limiting rods 3 are fixedly connected to the lower surface of the connecting strips 2, with one end of the limiting rod 3 extending into the receiving groove 10. Multiple limiting sliding holes are provided at the edge of the floating plate 12. The positioning rod 3 passes through the limiting sliding hole of the float plate 12. A limiting nut 7 is installed on the external thread of one end of the positioning rod 3. When in use, the drainage ditch cover can be laid at a designated location. When water accumulates, the water flows through the interior of the first drainage channel 8 and the second drainage channel 9 in sequence and is then discharged. If water backflows in a low-lying area, the float plate 12 set inside the collection trough 10 can adhere to the inner end face of the collection trough 10 under the action of buoyancy. Since the first drainage channel 8 and the second drainage channel 9 are alternately distributed, when the float plate 12 adheres to the inner end face of the collection trough 10, the float plate 12 can effectively block the first drainage channel 8, thereby preventing water backflow. The functionality and practicality are effectively improved.

[0026] Reference Figure 1 , Figure 2 A limiting connection groove 5 is provided on the upper surface of the concrete pouring body 4, and a permeable gravel layer 6 is laid on the upper surface of the concrete pouring body 4. The permeable gravel layer 6 fits into the interior of the limiting connection groove 5. By providing a limiting connection groove 5 on the upper surface of the concrete pouring body 4 and laying a permeable gravel layer 6 on the upper surface of the concrete pouring body 4, the permeable gravel layer 6 can be firmly attached to the upper surface of the concrete pouring body 4. The permeable gravel layer 6 can be used to improve the water permeability of the entire ditch cover surface, and at the same time improve the anti-slip performance of the ditch cover surface, thereby improving the practicality and functionality of the entire ditch cover.

[0027] Working principle: In use, the drainage ditch cover is laid in the designated location. When water accumulates, it flows through the interior of the first drainage channel 8 and the second drainage channel 9 before being discharged. If backflow occurs in low-lying areas, the float plate 12, located inside the collection trough 10, adheres to the inner end face of the collection trough 10 under the action of buoyancy. Because the first drainage channel 8 and the second drainage channel 9 are alternately distributed, when the float plate 12 adheres to the inner end face of the collection trough 10, the float plate 12 can effectively seal the drainage ditch. Blocking the first drainage channel 8 can prevent water backflow. During the entire use process, by setting a limiting connection groove 5 on the upper surface of the concrete pouring body 4, a permeable gravel layer 6 is laid on the upper surface of the concrete pouring body 4. The permeable gravel layer 6 fits into the inside of the limiting connection groove 5. At this time, the permeable gravel layer 6 can firmly adhere to the upper surface of the concrete pouring body 4. The permeable gravel layer 6 can be used to improve the water permeability of the entire ditch cover surface, and at the same time improve the anti-slip performance of the ditch cover surface.
