Abstract
Description
Technical Field
[0001] This application relates to the field of drainage system technology, and in particular to an environmentally friendly road drainage system. Background Technology
[0002] In urban road construction, roads typically include carriageways and sidewalks, with drainage channels on both sides of the carriageway. During rainy weather, rainwater from the sidewalks flows into the carriageway and then into the drainage channels. In existing technology, during the construction of sidewalks, a layer of permeable bricks is usually laid on the roadbed where the sidewalk is located. When it rains, rainwater can seep through the permeable bricks into the roadbed and then flow through the roadbed to the carriageway.
[0003] Regarding the aforementioned technologies, the inventors believe that when the rainfall is heavy, the rainwater does not have enough time to seep from the permeable bricks into the roadbed and flows towards the carriageway, making the sidewalk prone to water accumulation. Utility Model Content
[0004] To reduce the probability of water accumulation on sidewalks, this application provides an environmentally friendly road drainage system.
[0005] The environmentally friendly road drainage system provided in this application adopts the following technical solution:
[0006] An environmentally friendly road drainage system includes a roadbed; it also includes drainage base bricks laid on the roadbed and permeable bricks laid on the drainage base bricks; the top surface of the drainage base bricks has an arrangement groove for arranging the permeable bricks, and the bottom of the permeable bricks has an abutment protrusion for engaging with the arrangement groove; the permeable bricks and the drainage base bricks are connected by an adhesive structure; the adhesive structure includes a cement groove on the bottom surface of the arrangement groove, an adhesive protrusion on the abutment protrusion, and cement filling the space between the adhesive protrusion and the cement groove; the drainage base bricks have drainage channels along the length direction on the bottom surface of the arrangement groove.
[0007] By adopting the above technical solution, a groove is created on the top surface of the drainage base brick, allowing the abutment protrusion at the bottom of the permeable brick to engage within the groove, ensuring the permeable brick remains in the designated position when placed on the drainage base brick. The combination of the cement groove, the adhesive protrusion, and the cement results in ideal adhesion between the permeable brick and the drainage base brick. A drainage channel is created on the bottom surface of the groove, allowing rainwater seeping through the permeable brick to flow along the drainage channel towards the roadway, thereby reducing the probability of water accumulation on the sidewalk.
[0008] Optionally, the arrangement groove is an inverted isosceles trapezoidal groove with a horizontal bottom surface and an inclined surface connecting the two sides of the horizontal bottom surface; the drainage channel is opened on the horizontal bottom surface.
[0009] By adopting the above technical solution, the specific structure of the drainage channel is disclosed. The horizontal bottom surface and the inclined surface allow rainwater to flow into the drainage channel after seeping through the permeable bricks and onto the drainage bottom bricks, which helps to reduce the probability of rainwater stagnating on the drainage bottom bricks and causing water accumulation.
[0010] Optionally, the cement trough is formed on the inclined surface, and the drainage bottom brick is provided with the cement trough on both sides of the inclined surface of the arrangement trough. Both sides of the abutting protrusion have adhesive protrusions that correspond one-to-one with the cement trough.
[0011] By adopting the above technical solution, and by setting cement troughs on both sides of the arrangement groove and adhesive protrusions on both sides of the abutment protrusion, it is helpful to improve the bonding strength between the permeable brick and the drainage bottom brick.
[0012] Optionally, the drainage bottom brick is provided with overflow grooves and connecting grooves on both sides of the cement trough, and the depth of the overflow grooves is less than the depth of the cement trough.
[0013] By adopting the above technical solution, the overflow trough and the connecting trough are designed so that when the permeable brick is placed on the drainage bottom brick, the excess cement in the cement trough can flow into the overflow trough along the connecting trough, which helps to reduce the probability of cement accumulating on the inclined surface, thereby helping to keep the top surface of the permeable brick level.
[0014] Optionally, the top of both ends of the drainage bottom brick is provided with a horizontal section, and both ends of the permeable brick have abutting sections for abutting and cooperating with the horizontal sections.
[0015] By adopting the above technical solution, by setting horizontal sections at the top of both sides of the drainage bottom brick, the horizontal sections can support the abutment sections at both ends of the permeable brick, which helps to reduce the probability of damage to both sides of the drainage bottom brick and the permeable brick.
[0016] Optionally, the permeable brick has notches and grooves on both sides that extend through the upper and lower surfaces.
[0017] By adopting the above technical solution, the notch groove allows rainwater to flow into the drainage bottom bricks through the notch grooves when there is heavy rainfall, which helps to reduce the probability of water accumulation on the permeable bricks.
[0018] Optionally, the drainage base brick is provided with a filter screen for covering the opening of the drainage channel.
[0019] By adopting the above technical solution, the filter screen helps reduce the probability of impurities from the roadway entering the drainage channel and clogging it.
[0020] Optionally, a limiting strip is installed on the drainage bottom brick at the drainage channel, and the top surface of the limiting strip is in contact with the bottom surface of the permeable brick.
[0021] By adopting the above technical solution, placing the limiting strip in the drainage channel before placing the permeable brick on the drainage bottom brick helps reduce the probability of cement residue remaining in the drainage channel during construction, thus affecting the drainage effect.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. An environmentally friendly road drainage system, wherein a groove is opened in the drainage bottom brick so that the abutting protrusion of the permeable brick can be arranged in the groove, and a drainage channel is opened on the bottom surface of the groove so that water seeping from the permeable brick can flow through the groove into the drainage channel and then be discharged, which helps to reduce the probability of water accumulation on the sidewalk.
[0024] 2. By setting the drainage channel as an inverted isosceles trapezoidal structure, water seeping down from the permeable brick can flow along the inclined surface and the horizontal bottom surface into the drainage channel;
[0025] 3. By opening cement grooves on both inclined surfaces of the drainage base brick and setting adhesive protrusions on the abutting protrusions that correspond one-to-one with the two cement grooves, it is helpful to improve the bonding strength of the permeable brick to the drainage base brick.

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0032] This application discloses an environmentally friendly road drainage system.
[0033] Reference Figure 1 An environmentally friendly road drainage system includes a roadbed 1, drainage base bricks 2 laid on the roadbed 1, permeable bricks 3 laid on the drainage base bricks 2, and an adhesive structure for bonding the permeable bricks 3 to the drainage base bricks 2.
[0034] Reference Figure 1 and Figure 2 The drainage base bricks 2 are arranged side by side on the roadbed 1 along the length of the sidewalk. In this embodiment, the drainage base bricks 2 are formed by concrete casting, and multiple drainage base bricks 2 are cast integrally. The top surface of the drainage base bricks 2 has a groove 21 that runs through both the front and rear sides. The groove 21 is a through groove structure with an inverted isosceles trapezoidal cross-section. The groove 21 has a horizontal bottom surface 211 at the bottom and an inclined surface 212 that connects the two sides of the horizontal bottom surface 211 and is arranged upwardly. The drainage base bricks 2 have a drainage channel 213 for drainage along the length of the horizontal bottom surface 211. The bottom surface of the drainage channel 213 is arranged downwardly on the side facing the roadway. In order to reduce the probability of impurities entering the drainage channel 213 from the roadway, a filter screen 4 is provided on the side of the drainage channel 213 facing the roadway to cover the opening.
[0035] Reference Figure 2 The drainage bottom brick 2 has a horizontal section 22 formed on the top of both sides of the arrangement groove 21 for supporting the permeable brick 3. The horizontal section 22 has a support surface 221 that fits into the permeable brick 3.
[0036] Reference Figure 1 and Figure 2 The permeable bricks 3 are arranged side by side along the length of the drainage bottom bricks 2. Each permeable brick 3 includes a brick body 31 and an abutting protrusion 32 located below the brick body 31 and engaging with the arrangement groove 21. The brick body 31 has a square overall structure and is integrally formed with the abutting protrusion 32. An abutting section 311 is formed between the brick body 31 and the abutting protrusion 32, abutting against the support surface 221 of the horizontal section 22. The abutting section 311 has an abutting surface 3111 that fits against the support surface 221. The brick body 31 has notches 312 extending through its upper and lower surfaces on both sides along its length. Permeable holes 313 are formed in the notches 312 of adjacent brick bodies 31. The abutting protrusion 32 has a first contact surface 321 for contacting the horizontal bottom surface 211 of the arrangement groove 21 and a second contact surface 322 for contacting the inclined surface 212.
[0037] Reference Figure 2 and Figure 3 The adhesive structure includes a cement groove 23 vertically downwardly formed on the inclined surface 212, an adhesive protrusion 323 provided on the second bonding surface 322 and extending downward, and cement 5 filling the space between the cement groove 23 and the adhesive protrusion 323. In this embodiment, the drainage bottom brick 2 has cement grooves 23 on both sides of the inclined surface 212 of the arrangement groove 21, and the abutment protrusion 32 has an adhesive protrusion 323 on the second bonding surface 322 and is arranged corresponding to the two cement grooves 23. The cement groove 23 is a through groove structure that runs through the length of the drainage bottom brick 2. In order to reduce the probability that the adhesive protrusion 323 will squeeze the cement 5 to the inclined surface 212 when the abutment protrusion 32 is arranged in the arrangement groove 21, thereby affecting the levelness of the permeable brick 3, the drainage bottom brick 2 has an overflow groove 24 vertically downwardly formed on both sides of the cement groove 23 and a connecting groove 25 connecting the overflow groove 24 and the cement groove 23. The overflow groove 24 and the connecting groove 25 are both through groove structures that run through both the front and rear sides. When there is a lot of cement 5 in the cement tank 23, the adhesive protrusion 323 squeezes the cement 5, causing the cement 5 to flow from the connecting tank 25 into the overflow tank 24, thereby reducing the probability of cement 5 remaining on the inclined surface 212.
[0038] Reference Figure 2 and Figure 4 Before placing the permeable brick 3 on the drainage base brick 2, a limiting strip 6 is installed on the drainage base brick 2 at the drainage channel 213. The limiting strip 6 is a square wooden strip structure, and its cross-section is adapted to the cross-section of the drainage channel 213. The length of the limiting strip 6 is greater than the length of the drainage channel 213. The limiting strip 6 is installed in the drainage channel 213, and then cement 5 is filled into the cement groove 23. The permeable brick 3 is then placed on the drainage base brick 2. After the permeable brick 3 and the drainage base brick 2 are bonded, the limiting strip 6 is removed from the drainage channel 213, making it less likely for cement 5 to remain in the drainage channel 213, thus reducing the probability of the drainage channel 213 becoming clogged.
[0039] Combination Figures 1 to 4 The implementation principle of an environmentally friendly road drainage system according to an embodiment of this application is as follows: multiple drainage base bricks 2 are poured in parallel along the length of the sidewalk, and a layer of permeable bricks 3 is laid on the drainage base bricks 2. The drainage base bricks 2 have arrangement grooves 21 and drainage channels 213 are formed on the bottom surface of the arrangement grooves 21. When it rains, rainwater seeps into the arrangement grooves 21 through the permeable bricks 3, and flows into the drainage channels 213 through the inclined surface 212 and the horizontal bottom surface 211 of the arrangement grooves 21. Then, the rainwater flows from the drainage channels 213 to the roadway, thereby helping to reduce the probability of water accumulation on the sidewalk.
[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
