Description
Technical Field
[0001] This technical solution relates to the field of road construction technology, and in particular to a road drainage structure. Background Technology
[0002] As is well known, drainage structures on both sides of roads can quickly drain surface water, preventing puddles or waterlogged areas from forming and preventing asphalt or concrete from loosening, cracking, or sinking due to rainwater soaking, thus reducing the road's service life. Currently, existing technologies mainly fall into two categories. The first type, as shown in the attached... Figure 1 As shown, a curb is installed along the side of the road, and a drainage ditch is laid behind the curb using cement or curved stones. Drainage holes are made in the curb so that water from the road surface can enter the drainage ditch through the drainage holes. Another method, as shown in the attached diagram... Figure 2 As shown, the middle of the curbstone is hollowed out to form a drainage ditch, and drainage holes are made on the curbstone. The drainage effect is achieved by connecting the curbstones one by one to form a continuous drainage ditch.
[0003] However, these existing technologies have the following shortcomings: 1. Lack of overall integrity: Each curbstone is arranged independently, making it prone to loosening and displacement under vehicle loads and pedestrian activity. This increases the gaps between the curbstones, allowing water from the drainage ditches to seep into the ground, which over time erodes the soil structure and affects foundation stability. Furthermore, the frequent earthquakes in our province further exacerbate the loosening and displacement of the curbstones. 2. Construction is inconvenient, mainly in two aspects: First, the existing technology requires multiple steps to install the drainage system, including laying curbstones, constructing cement ditches, and allowing the cement to dry, extending the construction period; second, material transportation is inefficient and has a high damage rate. Since this technical solution is intended for use in prisons, long-term construction and repeated transportation will increase the risk of prison breaks. 3. Prisons have extremely high requirements for hygiene and environment; existing technologies are not aesthetically pleasing and are difficult to prevent rodents. Therefore, a technical solution that can simultaneously solve the above problems is needed. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a road drainage structure that is structurally stable, quick and convenient to construct, neat and aesthetically pleasing, and provides good environmental control. The specific solution is as follows.
[0005] A road drainage structure is characterized by having multiple curbstone drainage structures arranged between the road and the green belt, with water collection pools at their ends or in the middle.
[0006] The aforementioned curbstone drainage structure includes a curbstone with drainage holes extending from front to back. A back plate is provided on the back side of the curbstone, forming a U-shaped drainage ditch between the curbstone and the back plate. A step is provided above the drainage ditch, with the height of the step being lower than the height of the back plate. Positioning holes are provided on the step.
[0007] A partition with drainage holes is fastened onto the step, and positioning posts are provided at the four corners of the partition, which are then fixed in place through the positioning holes.
[0008] The partition is covered with pebbles.
[0009] The aforementioned curbstone drainage structure has a U-shaped drainage ditch with one end protruding outward to form a U-shaped convex edge, and the other end concave inward to form a U-shaped groove, with the convex edge and groove cooperating with each other.
[0010] The aforementioned curbstone drainage structure has rounded corners at the top of the curbstone.
[0011] The aforementioned curbstone drainage structure has positioning holes located in the middle of the steps, allowing adjacent curbstone drainage structures to be connected after the partitions are fastened together.
[0012] The spaces between the curbstone drainage structures are filled with waterproof sealant.
[0013] The drainage structure of the curbstone has its drainage holes set at an angle, with the front hole position higher than the back hole position.
[0014] The aforementioned curbstone drainage structure has drainage holes located on the back of the drainage ditch or above the drainage ditch.
[0015] The curbstone drainage structure has a curbstone width that matches the width of the drainage ditch, and the top shape of the curbstone matches the bottom shape of the drainage ditch.
[0016] The aforementioned water collection tank is sealed with tempered glass or a grating.
[0017] Compared with existing technologies, this technical solution achieves the following technical effects: (1) Enhances the integrity and sealing of the drainage structure, avoiding loosening, displacement, and increased gaps caused by vehicle loads, pedestrian activities, or earthquakes; (2) Efficient and convenient construction reduces the construction cycle and transportation frequency, thereby reducing the risk of escape; (3) Effectively isolates rats, optimizes the environment, and achieves a clean and beautiful appearance.

Detailed Implementation
[0027] Example 1, see appendix Figure 1-8 A road drainage structure, characterized in that multiple curbstone drainage structures 3 are arranged between the road 1 and the green belt 2, and a water collection pool 5 is provided at the end or middle of each structure.
[0028] The curbstone drainage structure 3 includes a curbstone 3-1 with drainage holes running through the front and back. A back plate 3-3 is provided on the back side of the curbstone, and a U-shaped drainage ditch 3-2 is formed between the curbstone and the back plate. A step 3-4 is provided above the drainage ditch, and the height of the step is lower than the height of the back plate. A positioning hole 3-5 is provided on the step.
[0029] A partition 4 with a drain hole 4-1 is fastened onto the step. Positioning posts 4-2 are provided under the four feet of the partition and are fixed through the positioning holes.
[0030] The partition is covered with pebbles.
[0031] The aforementioned curbstone drainage structure has a U-shaped drainage ditch with one end protruding outward to form a U-shaped convex edge 3-6, and the other end concave inward to form a U-shaped groove, with the convex edge and groove cooperating with each other.
[0032] The aforementioned curbstone drainage structure has rounded corners at the top of the curbstone.
[0033] The aforementioned curbstone drainage structure has positioning holes located in the middle of the steps, allowing adjacent curbstone drainage structures to be connected after the partitions are fastened together.
[0034] The spaces between the curbstone drainage structures are filled with waterproof sealant.
[0035] The drainage structure of the curbstone has its drainage holes set at an angle, with the front hole position higher than the back hole position.
[0036] The aforementioned curbstone drainage structure has its drainage holes located on the back side within the drainage ditch.
[0037] The curbstone drainage structure has a curbstone width that matches the width of the drainage ditch, and the top shape of the curbstone matches the bottom shape of the drainage ditch.
[0038] The aforementioned water collection tank is sealed with tempered glass or a grating.
[0039] The principle behind this technical solution is:
[0040] During construction, firstly, excavate a roadbed of the corresponding width according to the width of the curbstone drainage structure, and then lay the curbstone drainage structure in a linear arrangement. When laying, use partitions to connect adjacent curbstone drainage structures, and fill the gaps between adjacent curbstones with waterproof sealant. Then, set up a water collection pool in a suitable location. Finally, lay pebbles on the partitions.
[0041] Further explanation of the effects of this technical solution:
[0042] 1. The drainage structure formed by this technical solution has strong integrity: By connecting adjacent curbstone drainage structures together through staggered partitions, the integrity is improved, and loosening, displacement, and increased gaps are avoided due to vehicle load, pedestrian activity or earthquake activity.
[0043] 2. This technical solution has strong sealing performance: Because there are interlocking convex edges and grooves at both ends of the drainage ditch, the convex edges are fastened to the adjacent grooves, which improves the tightness. In addition, the waterproof sealant is filled and the partitions are staggered and fastened. Under their combined action, a tight connection is formed and the waterproof effect is excellent, which prevents water in the drainage ditch from seeping into the ground through the gaps and eroding the soil structure and affecting the stability of the foundation.
[0044] 3. This technical solution is efficient and convenient to construct: (1) The curbstone drainage structure can be integrally formed by pouring cement into the curbstone mold 6, as shown in the attached figure. Figure 7 As shown, insert rod 6-1 into the mold. After the cement hardens, the position of the rod is the drainage hole. The initial curbstone drainage structure is manufactured outside the prison. During the later construction inside the prison, it can be laid quickly, which greatly improves the construction efficiency; (2) The two curbstone drainage structures are rotated and interlocked, and tightly overlapped together (as shown in the attached figure). Figure 8-B), which can save space, allowing more materials to be transported in a single trip and reducing the number of transport trips; (3) Since the width of the curbstone is the same as the width of the drainage ditch, and the shape of the top of the curbstone is the same as the shape of the bottom of the drainage ditch, the top of the curbstone can be tightly embedded in the drainage ditch when it is rotated and buckled, avoiding damage to the top of the curbstone or the drainage ditch due to bumps and collisions during transport. In summary, it speeds up the construction efficiency in the prison, reduces the construction cycle, and reduces the frequency of transport, thereby reducing the risk of prison break;
[0045] 4. After installation, this technical solution conceals the drainage ditch with pebbles on the partition, achieving a neat and aesthetically pleasing appearance. Furthermore, compared to existing technologies, the reduced size of the drainage holes creates a relatively isolated space inside and outside the drainage ditch, preventing rats from crossing and enhancing rodent control, thus meeting prison-level environmental requirements. It should be noted that the reduced drainage hole size can be compensated for by increasing the number of drainage holes, thereby balancing the drainage effect.
[0046] 5. The drainage ditch directs water to the sump, which can be used for irrigation of green belts. The top of the sump is sealed with tempered glass for easy observation of the water level, or the top of the sump is sealed with a grating to further improve drainage.
[0047] In summary, compared with the existing technology, this technical solution has the following advantages: (1) Enhanced overall drainage structure and sealing performance, preventing loosening, displacement, and increased gaps caused by vehicle loads, pedestrian activities, or earthquakes; (2) Efficient and convenient construction, reducing construction cycle and transportation frequency, thereby reducing the risk of escape; (3) Effective isolation of rats, optimization of the environment, and achieving a clean and beautiful appearance.
[0048] Example 2, see appendix Figure 8 A road drainage structure characterized by having multiple curbstone drainage structures arranged between the road and the green belt, with water collection pools at their ends or in the middle.
[0049] The aforementioned curbstone drainage structure includes a curbstone with drainage holes extending from front to back. A back plate is provided on the back side of the curbstone, forming a U-shaped drainage ditch between the curbstone and the back plate. A step is provided above the drainage ditch, with the height of the step being lower than the height of the back plate. Positioning holes are provided on the step.
[0050] A partition with drainage holes is fastened onto the step, and positioning posts are provided at the four corners of the partition, which are then fixed in place through the positioning holes.
[0051] The partition is covered with pebbles.
[0052] The aforementioned curbstone drainage structure has a U-shaped drainage ditch with one end protruding outward to form a U-shaped convex edge, and the other end concave inward to form a U-shaped groove, with the convex edge and groove cooperating with each other.
[0053] The aforementioned curbstone drainage structure has rounded corners at the top of the curbstone.
[0054] The aforementioned curbstone drainage structure has positioning holes located in the middle of the steps, allowing adjacent curbstone drainage structures to be connected after the partitions are fastened together.
[0055] The spaces between the curbstone drainage structures are filled with waterproof sealant.
[0056] The drainage structure of the curbstone has its drainage holes set at an angle, with the front hole position higher than the back hole position.
[0057] The aforementioned curbstone drainage structure has its drainage holes located on the back side above the drainage ditch.
[0058] The curbstone drainage structure has a curbstone width that matches the width of the drainage ditch, and the top shape of the curbstone matches the bottom shape of the drainage ditch.
[0059] The aforementioned water collection tank is sealed with tempered glass or a grating.
[0060] Further explanation of the technical effects of this embodiment:
[0061] In this technical solution, the drainage hole on the back is located above the drainage ditch, while in Embodiment 1, the drainage hole on the back is located inside the drainage ditch. The differences between the two are shown in the attached figure. Figure 8 As shown, when the drainage hole is located above the drainage ditch on the back, during transportation, the two curbstone drainage structures are rotated and interlocked. Inserting the rod into the two drainage holes further secures the structures (as shown in the attached diagram). Figure 8 -D).
