Description
Technical Field
[0001] The present application relates to the field of urban drainage technology, and in particular to a prefabricated cover plate for an integrated ground drainage ditch. Background Art
[0002] With the acceleration of my country's urbanization process and the improvement of infrastructure construction, ground drainage systems are playing an increasingly important role in urban construction. Waterside ditches are mostly arranged on both sides of the road, and a small number are arranged on one side. Generally, road drainage ditches are mostly made of rectangular cross-section and cast-in-place concrete. In order to ensure the safety of vehicles or pedestrians, the drainage ditches are covered with reinforced concrete covers.
[0003] In the actual implementation process, the drainage ditch and the cover plate are both prefabricated with reinforced concrete. During installation, the prefabricated drainage ditch is first installed in a groove excavated on the ground, and then the cover plate is placed on the drainage ditch so that the cover plates are tightly pressed against each other.
[0004] However, as vehicles and other objects travel on the road, the road vibrates, and the vibration is transmitted to the gap between the two adjacent cover plates, causing the gap between the cover plates to become larger. The substances remaining in the drainage ditch may produce odor, and the odor will overflow through the gap between the two cover plates, affecting people on the road and causing discomfort to people, which is a shortcoming. Utility Model Content
[0005] In order to improve the emission of foreign matter in the drainage ditch, the present application provides a prefabricated cover plate of an integrated floor drainage ditch.
[0006] The present application provides a prefabricated cover plate for integrated floor drainage ditch using the following technical solution:
[0007] A prefabricated cover plate of an integrated floor drainage ditch comprises a plurality of prefabricated cover plates mounted on the drainage ditch, wherein the plurality of prefabricated cover plates are arranged along the length direction of the drainage ditch, a sealing member for sealing is provided between two adjacent prefabricated cover plates, a sealing strip is provided between the prefabricated cover plates and the drainage ditch, a drainage annular groove is circumferentially opened on the prefabricated cover plate, a drainage pipe is connected to the drainage annular groove, an end of the drainage pipe facing away from the drainage annular groove extends to the drainage ditch, and an overflow prevention member for sealing the drainage pipe is provided on the drainage pipe.
[0008] By adopting the above technical solution, workers press the sealing strip onto the drain ditch through the prefabricated cover plate, and then install the seal at the contact point of two adjacent prefabricated cover plates. When it rains, rainwater flows into the drainage ring groove on the prefabricated cover plate, the overflow prevention piece opens the drain pipe, and then flows into the drain ditch through the drain pipe; when odor is generated in the drain ditch, the overflow prevention piece blocks the drain pipe, thereby preventing the overflow of odor in the drain ditch, reducing the impact on people on the road, and helping to protect the surrounding environment.
[0009] Optionally, the sealing member includes a waterproof membrane and a drainage cover arranged between two adjacent prefabricated cover plates, the prefabricated cover plates are located between the waterproof membrane and the drainage cover, the drainage cover is located between the prefabricated cover plates and the drainage ditch, and the drainage cover is connected to a through pipe, which is connected to the drainage ditch.
[0010] By adopting the above technical solution, the waterproof roll can be made of elastic rubber material. When the road vibrates, the waterproof roll will deform accordingly to adapt to the vibration of the road and seal the gaps between the prefabricated cover plates.
[0011] Optionally, a protective plate is provided between two adjacent prefabricated cover plates, the protective plate is provided on the waterproof membrane, and patterned protrusions are provided on the protective plate.
[0012] By adopting the above technical solution, the protective plate protects the waterproof membrane, reducing the possibility of accidental damage to the waterproof membrane. At the same time, the raised pattern increases the friction on the surface of the protective plate, which is beneficial to improving the safety of people on rainy days. In addition, the raised pattern is beneficial to improving the aesthetics of the protective plate.
[0013] Optionally, the overflow prevention component includes a sealing plate rotatably arranged on the drain pipe, and a torsion spring is provided at the rotation center of the sealing plate and the drain pipe.
[0014] By adopting the above technical solution, under the action of the torsion spring, the sealing plate blocks the drain pipe. When it rains, as the rainwater in the drain pipe increases to a certain weight, the torsion spring deforms, the sealing plate is opened, and the rainwater in the drain pipe is discharged; when it is not raining, under the action of the torsion spring, the sealing plate seals the drain pipe again.
[0015] Optionally, a filter screen is provided in the drainage ring groove, a rocker is provided on the sealing plate, a collision rod is slidably provided on the drainage pipe, a connecting rod is hinged between the rocker and the collision rod, and the collision rod is used to impact the filter screen.
[0016] By adopting the above technical solution, the filter screen prevents external debris from entering the drainage ring groove. When the sealing plate rotates to open, the sealing plate drives the rocker to rotate, and the rocker pushes the impact rod through the connecting rod to hit the filter screen, causing the filter screen to vibrate, thereby opening the blocked mesh opening on the filter screen.
[0017] Optionally, the sealing plate is arranged on the drain pipe at an angle, the highest inclined point of the sealing plate is rotatably arranged on the drain pipe, and the rocker is arranged at the highest point of the sealing plate.
[0018] By adopting the above technical solution, the inclined sealing plate, on the one hand, facilitates the sealing plate to open the drain pipe; on the other hand, when the impact rod is reset, under the action of the weight of the impact rod, the impact rod pushes the rocker to rotate through the connecting rod, and the rotation of the rocker presses the sealing plate tightly against the drain pipe.
[0019] Optionally, a support plate is provided above the drainage ring groove on the prefabricated cover plate, and there is a gap between the circumferential edge of the support plate and the circumferential edge of the drainage ring groove. A leveling plate is provided on the support plate, and the upper surface of the leveling plate is flush with the upper surface of the protective plate.
[0020] By adopting the above technical solution, the gap between the support plate and the circumferential edge of the drainage ring groove reduces the possibility of large objects entering the drainage ring groove. The support plate here can be made of stainless steel plate, which reduces the possibility of accidents caused by people accidentally stepping into the drainage ring groove.
[0021] Optionally, the prefabricated cover plate includes an outer base layer, a support layer is provided on the outer base layer, a buffer layer is provided between the outer base layer and the support layer, the drainage ring groove is opened on the buffer layer, and the support plate is provided on the support layer.
[0022] By adopting the above technical solution, when the supporting layer is squeezed or exposed to a high temperature environment, under the restrictive action of the outer base layer, the supporting layer laterally squeezes the buffer layer, and the buffer layer deforms, thereby reducing the possibility of the outer base layer being damaged by lateral squeezing, which is beneficial to improving the service life of the outer base layer, thereby extending the service life of the prefabricated cover plate.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. Workers press the sealing strip against the gutter through the prefabricated cover plate, and then install the seal at the contact point of two adjacent prefabricated cover plates. When it rains, rainwater flows into the drainage ring groove on the prefabricated cover plate, and the overflow prevention piece opens the drain pipe, and then flows into the gutter through the drain pipe. When odor is generated in the gutter, the overflow prevention piece blocks the drain pipe, thereby preventing the odor from overflowing from the gutter, reducing the impact on people on the road and helping to protect the surrounding environment.
[0025] 2. Under the action of the torsion spring, the sealing plate blocks the drain pipe. When it rains, as the rainwater in the drain pipe increases to a certain weight, the torsion spring deforms, the sealing plate is opened, and the rainwater in the drain pipe is discharged. When it is not raining, the sealing plate is re-sealed under the action of the torsion spring;
[0026] 3. The inclined sealing plate makes it easier to open the drain pipe. On the other hand, when the impact rod is reset, under the action of the weight of the impact rod, the impact rod pushes the rocker to rotate through the connecting rod, and the rotation of the rocker presses the sealing plate tightly against the drain pipe.

[0031] The following is combined with Figure 1-3 This application is described in further detail.
[0032] The embodiment of the present application discloses a prefabricated cover plate of an integrated floor drainage ditch plate.
[0033] Reference Figure 1 A prefabricated cover plate of an integrated ground drainage ditch includes multiple prefabricated cover plates 2 mounted on a drainage ditch 1. The multiple prefabricated cover plates 2 are arranged along the length direction of the drainage ditch 1. A sealing member 3 for sealing is arranged between two adjacent prefabricated cover plates 2, and a sealing strip 4 is arranged between the prefabricated cover plates 2 and the drainage ditch 1.
[0034] Reference Figure 1 、 Figure 2 and Figure 3 The sealing member 3 includes a waterproof membrane 31 and a drainage cover 32 arranged between two adjacent prefabricated cover plates 2. The waterproof membrane 31 is made of an elastically deformable material. The waterproof membrane 31 is bonded to the top of the prefabricated cover plate 2 by an epoxy resin adhesive. The prefabricated cover plate 2 is located between the waterproof membrane 31 and the drainage cover 32. The drainage cover 32 is located between the prefabricated cover plate 2 and the drainage ditch 1. A through pipe 33 is connected to the drainage cover 32, and the through pipe 33 is connected to the drainage ditch 1.
[0035] Reference Figure 1 、 Figure 2 and Figure 3 The prefabricated cover plate 2 includes an outer base layer 21, on which a support layer 22 is prefabricated through a steel cage. A buffer layer 23 is filled between the outer base layer 21 and the support layer 22. A drainage ring groove 5 is opened circumferentially on the buffer layer 23, and a drainage pipe 6 is connected to the drainage ring groove 5. The end of the drainage pipe 6 facing away from the drainage ring groove 5 extends to the drainage ditch 1. The drainage pipe 6 passes through the buffer layer 23. A protective plate 8 is bonded between two adjacent prefabricated cover plates 2. The protective plate 8 is located above the waterproof membrane 31, and a patterned protrusion 9 is integrally formed on the protective plate 8.
[0036] Workers press the sealing strip 4 onto the drainage ditch 1 through the prefabricated cover plate 2, then install the waterproof membrane 31 and the drainage cover 32 at the contact point of the two adjacent prefabricated cover plates 2, and then install the protective plate 8 on the two prefabricated cover plates 2. When it rains, rainwater flows into the drainage ring groove 5 on the buffer layer 23. The rainwater flowing into the drainage ring groove 5 then flows into the drainage ditch 1 through the drain pipe 6.
[0037] Reference Figure 1 、 Figure 2 and Figure 3 , an overflow prevention part 7 for sealing the drain pipe 6 is arranged on the drain pipe 6, the overflow prevention part 7 includes a sealing plate 71 which is tilted and rotatably connected to the drain pipe 6, the highest point of the tilted sealing plate 71 is rotatably connected to the drain pipe 6, a torsion spring 72 is arranged at the rotation center of the sealing plate 71 and the drain pipe 6, a filter screen 10 is bolted in the drainage ring groove 5, a rocker 11 is welded at the highest point of the sealing plate 71, and a vertical impact rod 12 is slidably arranged on the drain pipe 6, a connecting rod 13 is hinged between the end of the rocker 11 away from the sealing plate 71 and the impact rod 12, and the impact rod 12 is used to impact the filter screen 10.
[0038] Reference Figure 1 、 Figure 2 and Figure 3 A support plate 14 is arranged above the drainage ring groove 5 on the prefabricated cover plate 2. The support plate 14 is fixedly installed on the upper surface of the support layer 22. The support plate 14 can be made of stainless steel material in the existing technology. There is a gap between the circumferential edge of the support plate 14 and the circumferential edge of the drainage ring groove 5. A leveling plate 15 is bonded to the support plate 14, and the upper surface of the leveling plate 15 is flush with the upper surface of the protective plate 8.
[0039] As the rainwater drives the debris to the prefabricated cover plate 2 , the gap between the support plate 14 and the circumferential edge of the drainage ring groove 5 prevents larger objects from entering the drainage ring groove 5 , and then the filter net 10 filters the rainwater flowing into the drainage ring groove 5 .
[0040] When rainwater accumulates to a certain amount in the drainage ring groove 5, the sealing plate 71 on the drainage pipe 6 can no longer block the drainage pipe 6. Under the action of the gravity of the water in the drainage pipe 6, the sealing plate 71 rotates, and the torsion spring 72 deforms. The rotation of the sealing plate 71 drives the rocker 11 to rotate synchronously. The rocker 11 pushes the impact rod 12 to rise through the connecting rod 13, and the impact rod 12 hits the filter screen 10.
[0041] The mesh opening on the filter screen 10 is shaken open, and the rainwater on the filter screen 10 continues to flow into the drain pipe 6. The above process is repeated until the rainwater in the drain pipe 6 is insufficient to push the sealing plate 71 to rotate. Under the action of its own gravity, the impact rod 12 pushes the rocker 11 through the connecting rod 13, and the rocker 11 drives the sealing plate 71 to re-block the drain pipe 6.
[0042] The implementation principle of the prefabricated cover plate of an integrated ground drainage ditch in an embodiment of the present application is as follows: workers press the sealing strip 4 onto the drainage ditch 1 through the prefabricated cover plate 2, and then install the waterproof membrane 31 and the drainage cover 32 at the contact point of the two adjacent prefabricated cover plates 2, and then install the protective plate 8 on the two prefabricated cover plates 2 themselves. When it rains, rainwater flows into the drainage ring groove 5 on the buffer layer 23, and the rainwater flowing into the drainage ring groove 5 then flows into the drainage ditch 1 through the drainage pipe 6.
[0043] As the rainwater drives the debris to the prefabricated cover plate 2 , the gap between the support plate 14 and the circumferential edge of the drainage ring groove 5 prevents larger objects from entering the drainage ring groove 5 , and then the filter net 10 filters the rainwater flowing into the drainage ring groove 5 .
[0044] When rainwater accumulates to a certain amount in the drainage ring groove 5, the sealing plate 71 on the drainage pipe 6 can no longer block the drainage pipe 6. Under the action of the gravity of the water in the drainage pipe 6, the sealing plate 71 rotates, and the torsion spring 72 deforms. The rotation of the sealing plate 71 drives the rocker 11 to rotate synchronously. The rocker 11 pushes the impact rod 12 to rise through the connecting rod 13, and the impact rod 12 hits the filter screen 10.
[0045] The mesh opening on the filter screen 10 is shaken open, and the rainwater on the filter screen 10 continues to flow into the drain pipe 6. The above process is repeated until the rainwater in the drain pipe 6 is insufficient to push the sealing plate 71 to rotate. Under the action of its own gravity, the impact rod 12 pushes the rocker 11 through the connecting rod 13, and the rocker 11 drives the sealing plate 71 to re-block the drain pipe 6. At the same time, the restoring deformation force of the torsion spring 72 presses the sealing plate 71 tightly against the drain pipe 6.
[0046] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
