Description

Technical Field

[0001] This application relates to the field of sidewalk drainage technology, specifically a sidewalk drainage structure. Background Technology

[0002] A sidewalk is a section of a road that is separated by curbs, railings, or other similar facilities and is dedicated to pedestrian traffic. Sidewalks are very common in cities. In order to ensure that pedestrians can walk normally on sidewalks during rainy weather, the drainage function of sidewalks is also very important. Therefore, drainage structures are usually installed during the construction of sidewalks.

[0003] In existing technologies, when performing drainage operations on sidewalks, drainage ditches are usually set up on one side of the sidewalk, and a cover plate with water inlet holes is installed on the top of the drainage ditch. Then, rainwater on the sidewalk flows into the drainage ditch through the water inlet holes on the cover plate to perform drainage operations. However, most of the cover plates are directly embedded in the drainage ditch. When the water flow in the drainage ditch is large or the cover plate is subjected to external impact for a long time, the cover plate is prone to displacement, thus exposing the drainage ditch, affecting the normal walking of pedestrians and posing a low safety risk. Utility Model Content

[0004] To address the issue of insufficient safety in existing technologies, this utility model provides a sidewalk drainage structure.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows: This utility model provides a sidewalk drainage structure, including a roadbed, a base trench on the roadbed, a facing brick paved in the base trench, a drainage ditch on one side of the roadbed, a drainage channel in the drainage ditch, a guide hole at the bottom of the base trench communicating with the drainage channel, a cover plate on the top of the drainage ditch, filter holes on the cover plate, an adjusting rod rotatably mounted on the cover plate, a locking block fixedly mounted on one end of the adjusting rod at the bottom of the cover plate, a sliding groove aligned with the adjusting rod along the vertical direction on the side wall of the drainage channel, and a limiting groove at the bottom of the sliding groove matching the locking block.

[0006] Preferably, the drainage channel has a slot at the top of the drainage trough, a sliding groove at the bottom of the slot, and a cover plate embedded in the slot. When the cover plate is installed, the bottom of the locking block abuts against the bottom of the sliding groove during the lowering of the cover plate, and both sides of the cover plate are embedded in the slot respectively. The slot supports and further limits the cover plate to ensure its stability.

[0007] Preferably, the number of adjusting rods is multiple sets and they are spaced apart on both sides of the cover plate. By setting multiple sets of adjusting rods, the cover plate can be limited at multiple points. During the cover plate installation operation, the workers enhance the stability of the cover plate by engaging the locking blocks at the bottom of the multiple sets of adjusting rods with the limiting grooves. This prevents the locking blocks on some adjusting rods from accidentally disengaging from the limiting grooves, which would cause the cover plate to shift and fall out of the drainage channel.

[0008] Preferably, the trench is laid with geotextile, pebble layer and leveling layer from bottom to top, and facing bricks are laid on top of the leveling layer. The geotextile, pebble layer and leveling layer laid in the trench allow the facing bricks to be laid flat on the leveling layer, ensuring the stability of pedestrians. The pebble layer provides stable support for the leveling layer and facing bricks above, ensuring the strength and service life of the sidewalk. Rainwater that has permeated through the facing bricks will be filtered by the geotextile before flowing into the drainage hole, preventing impurities carried in the rainwater from entering the drainage ditch.

[0009] Preferably, the bottom of the trench is inclined, with the height of the side of the trench near the drainage ditch being lower than the height of the side away from the drainage ditch. By setting the bottom of the trench to an inclined state, rainwater that has seeped through the bricks will flow along the inclined bottom wall when it collects at the bottom of the trench, and then collect on the side of the guide hole to flow into the drainage ditch, ensuring that the rainwater in the trench is completely discharged, avoiding water accumulation in the trench, and improving drainage efficiency.

[0010] Preferably, the facing brick is provided with multiple sets of through holes at intervals around its perimeter. The multiple sets of through holes around the facing brick allow rainwater to flow down through the through holes and enter the bottom of the base trench, thereby improving the rainwater drainage efficiency and preventing water accumulation on the facing brick.

[0011] Preferably, the surface of the brick is provided with staggered grooves, the two ends of which are connected to the top of the through hole. By providing staggered grooves on the surface of the brick, the friction of pedestrians when walking is increased, ensuring the safety of pedestrians. In addition, the grooves on the brick can guide rainwater to flow into the through hole, thereby improving the rainwater drainage efficiency.

[0012] The advantages of adopting the above technical solution are: This invention includes a roadbed with a foundation trench on it, paved with facing bricks. A drainage ditch is located on one side of the roadbed, containing a drainage channel. A guide hole connecting the drainage channel is located at the bottom of the foundation trench. A cover plate with filter holes is located on the top of the drainage ditch. An adjusting rod is rotatably mounted on the cover plate, with a locking block fixed to one end of the adjusting rod at the bottom of the cover plate. A sliding groove aligned with the adjusting rod is located on the side wall of the drainage channel in the vertical direction. A limiting groove matching the locking block is located at the bottom of the sliding groove. When installing the cover plate, the operator rotates the adjusting rod on the cover plate to adjust the locking block at the bottom of the adjusting rod and the limiting groove at the bottom of the sliding groove, thereby achieving vertical limiting of the cover plate, ensuring its stability, and improving pedestrian safety.

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0017] like Figure 1-4 As shown in the figure, this utility model embodiment discloses a sidewalk drainage structure, including a roadbed 1, a base trench on the roadbed 1, a facing brick 2 laid in the base trench, a drainage ditch 3 on one side of the roadbed 1, a drainage channel 3 in the drainage channel 3, a drainage trough 301 in the drainage channel 3, a guide hole 305 at the bottom of the base trench communicating with the drainage trough 301, a cover plate 4 on the top of the drainage channel 3, a filter hole 401 on the cover plate 4, an adjusting rod 5 rotatably mounted on the cover plate 4, a locking block 501 fixedly mounted on one end of the adjusting rod 5 at the bottom of the cover plate 4, a sliding groove 303 aligned with the adjusting rod 5 along the vertical direction on the side wall of the drainage trough 301, and a limiting groove 304 fitted with the locking block 501 at the bottom of the sliding groove 303.

[0018] In at least one embodiment, the drainage channel 3 is provided with a slot 302 at the top of the drainage trough 301, and a slide 303 is located at the bottom of the slot 302. The cover plate 4 is embedded in the slot 302. When the cover plate 4 is installed, when the worker lowers the cover plate 4, the bottom of the locking block 501 abuts against the bottom of the slide 303, and the two sides of the cover plate 4 are respectively embedded in the slot 302. The slot 302 supports and further limits the cover plate 4 to ensure the stability of the cover plate 4.

[0019] In at least one embodiment, the number of adjusting rods 5 is multiple sets and they are spaced apart on both sides of the cover plate 4. By setting multiple sets of adjusting rods 5, the cover plate 4 can be limited at multiple points. When the cover plate 4 is installed, the workers enhance the stability of the cover plate 4 by engaging the locking blocks 501 at the bottom of the multiple sets of adjusting rods 5 with the limiting grooves 304. This prevents the locking blocks 501 on some adjusting rods 5 from accidentally disengaging from the limiting grooves 304, which would cause the cover plate 4 to shift and detach from the drainage groove 301.

[0020] In at least one embodiment, geotextile 8, pebble layer 6, and leveling layer 7 are laid from bottom to top in the foundation trench. Facing brick 2 is laid on top of leveling layer 7. Through the geotextile 8, pebble layer 6, and leveling layer 7 laid in the foundation trench, facing brick 2 can be laid flat on leveling layer 7, ensuring the stability of pedestrians. The pebble layer 6 provides stable support for the leveling layer 7 and facing brick 2 above, ensuring the strength and service life of the sidewalk. Rainwater that has permeated through facing brick 2 will be filtered by geotextile 8 before flowing into the drainage hole 305, preventing impurities carried in the rainwater from entering the drainage ditch 3.

[0021] In at least one embodiment, the bottom of the trench is arranged at an inclination, and the height of the side of the bottom of the trench near the drainage ditch 3 is lower than the height of the side away from the drainage ditch 3. By setting the bottom of the trench at an inclination, the rainwater that has seeped through the bricks 2 will flow along the inclination bottom wall when it collects at the bottom of the trench, and then collect on the side of the guide hole 305 and flow into the drainage ditch 3, ensuring that the rainwater in the trench is completely discharged, avoiding water accumulation in the trench, and improving drainage efficiency.

[0022] In at least one embodiment, multiple sets of through holes 201 are provided around the perimeter of the brick 2. By providing multiple sets of through holes 201 around the perimeter of the brick 2, rainwater can also flow down along the through holes 201 and enter the bottom of the base trench, thereby improving the drainage efficiency of rainwater and preventing water accumulation on the brick 2.

[0023] In at least one embodiment, the surface of the brick 2 is provided with staggered grooves 202, the two ends of which are connected to the top of the through hole 201. By providing staggered grooves 202 on the surface of the brick 2, the friction of pedestrians when walking is increased, ensuring the safety of pedestrians. In addition, the grooves 202 on the brick 2 can guide rainwater to flow into the through hole 201, thereby improving the rainwater drainage efficiency.

[0024] During the drainage operation of the sidewalk, the sidewalk base 1 is paved with permeable bricks 2. After rainwater flows into the surface of the bricks 2, it seeps downwards and flows into the bottom of the base trench. Then, the rainwater in the base trench flows into the drainage ditch 3 on one side through the guide hole 305. The drainage channel 301 in the drainage ditch 3 collects and discharges the rainwater. When the rain is heavy, the rainwater can flow along the surface of the bricks 2 to the cover plate 4 on top of the drainage ditch 3, and then enter the drainage channel 301 through the filter hole 401 on the cover plate 4, preventing water accumulation on the sidewalk and ensuring normal pedestrian walking. When the workers install the cover plate 4 on the drainage channel 3, they rotate the adjusting rod 5 on the cover plate 4, so that the locking block 501 at the bottom of the adjusting rod 5 is rotated to the side closer to the middle of the drainage channel 301. Then, the workers lower the cover plate along the drainage channel 301. 4. During the descent of the cover plate 4, the adjusting rod 5 is aligned with the sliding groove 303 on the side wall of the drainage channel 301. This allows the adjusting rod 5 and the locking block 501 to slide down the slider as the cover plate 4 descends. When the bottom of the locking block 501 abuts against the bottom of the sliding groove 303, the cover plate 4 stops descending. At this point, the top of the cover plate 4 is flush with the top of the drainage channel 3. Then, the operator rotates the adjusting rod 5, causing the locking block 501 to rotate and rotate into the limiting groove 304 at the bottom of the sliding groove 303. This engages the locking block 501 with the limiting groove 304, thus limiting the vertical position of the cover plate 4. The operation is convenient, making it easy for operators to load and unload the cover plate 4. This prevents the cover plate 4 from shifting and detaching from the drainage channel 301 when subjected to external collisions or water flow impacts, ensuring normal pedestrian passage and greatly improving safety.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
