Description

Technical Field

[0001] This utility model relates to the field of outdoor landscape trail technology, specifically to a drainage structure for outdoor landscape trails that prevents water accumulation. Background Technology

[0002] Outdoor landscape walkways, as core supporting facilities for urban parks, scenic spots, and residential areas, combine transportation connections, ecological landscapes, and leisure and recreation functions. By integrating natural elements and humanistic design, they provide people with comfortable spaces to get close to the outdoors and are an important carrier for improving environmental quality and the happiness of life. However, traditional walkways often suffer from water accumulation problems due to insufficient drainage design, which not only affects the safety and experience of passage but also accelerates the aging of the walkway structure, breeds mosquitoes, and damages the integrity of the landscape. To address this, water-proof drainage structures for outdoor landscape walkways have emerged. By optimizing the drainage path design and integrating core components such as permeable base layers, diversion channels, and collection wells, they achieve rapid infiltration and directional discharge of rainwater. This not only solves the water accumulation problem of traditional walkways but also protects the structural stability of the walkways, ensuring safe passage in all weather conditions. At the same time, it aligns with the concept of sponge city construction, enhancing the ecological adaptability and long-term use value of landscape walkways.

[0003] Chinese Utility Model Patent Publication No. CN221721282U discloses: a drainage structure for an ecological beach walkway. This drainage structure for an outdoor landscape walkway that prevents water accumulation includes a pedestrian walkway with a permeable pavement. Below the permeable pavement is a permeable concrete foundation, and below the permeable concrete foundation is a gravel water-stabilized layer. Below the gravel water-stabilized layer is a plain soil foundation. Drainage ditches are set on both sides of the pedestrian walkway. The top of the drainage ditches is equipped with a filter trough, the bottom of the filter trough is a grid plate, and pebbles or gravel are laid on top of the grid plate. A drainage pipe is connected to the bottom of the drainage ditch and is connected to a rainwater well. This utility model of a pedestrian walkway allows for infiltration and drainage during periods of light rainfall, preventing excessive mud and debris from being washed into the drainage ditch. It also meets the requirement for rapid drainage during periods of heavy rainfall. In special geographical environments, it can be used normally for a long time with low maintenance frequency, reducing maintenance costs. However, when the drainage pipe is damaged or aged, it cannot be partially disassembled and replaced; it must be replaced entirely, increasing maintenance costs. Furthermore, when repairing or replacing the drainage structure of this waterproof outdoor landscape walkway, the construction time is long, affecting user passage. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a drainage structure for outdoor landscape walkways that prevents water accumulation, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: an outdoor landscape walkway drainage structure for preventing water accumulation, including two drainage ditch sidewalls and a base layer disposed between the two drainage ditch sidewalls. A cushion layer is disposed on the top of the base layer. A stabilizing layer is disposed on the side of the cushion layer away from the base layer. A waterproof layer is disposed on the side of the stabilizing layer away from the cushion layer. An impermeable layer, a drainage pipe and a main drainage channel are disposed on the side of the waterproof layer away from the stabilizing layer. A permeable surface layer is disposed on the side of the impermeable layer, the drainage pipe and the main drainage channel away from the waterproof layer. A through groove is opened at the connection between the drainage pipe and the main drainage channel. A drainage groove is opened on the top of the opposite sides of the two drainage ditch sidewalls. Limiting blocks are provided on the top of both the drainage ditch sidewalls and the permeable surface layer. A drainage cover is disposed between the drainage ditch sidewalls and the top of the permeable surface layer.

[0006] Preferably, the number of the seepage-proof layers is four times the number of the base layers, the vertical cross-section of the seepage-proof layers has an outward convex structure, and the seepage-proof layers are symmetrically distributed about the transverse centerline of the embedded parts.

[0007] The above technical solution, with the number of the impermeable layers being four times the number of the base layers, the vertical cross-section of the impermeable layers having an outward convex structure, and the impermeable layers being symmetrically distributed about the transverse centerline of the embedded parts, prevents water seeping down from the permeable surface layer from entering the main drainage channel, thereby improving the drainage efficiency of the structure.

[0008] Preferably, the middle part of the sidewall of the drainage trough and the side of the permeable surface layer are both configured as an outward convex structure, and the top and bottom openings of the drainage trough are larger than the middle part.

[0009] The above technical solution uses an outwardly convex structure for the middle part of the drainage channel sidewall and the side of the permeable surface layer. The top and bottom openings of the drainage channel are larger than the middle design. This structure adopts the Venturi effect, which improves drainage efficiency. In rainy weather, the high-speed water flow can quickly drain the accumulated water, reducing the occurrence of water accumulation. Moreover, this structure does not require additional power and achieves the benefit of improved drainage efficiency through the structure alone, thus reducing costs.

[0010] Preferably, the number of drainage pipes is eight times the number of drainage ditch sidewalls, and the drainage pipes are symmetrically distributed about the vertical centerline of the main drainage channel.

[0011] The above technical solution, through the design of multiple sets of drainage pipes, improves the structure's ability to drain and divert water simultaneously under extreme weather conditions such as heavy rain and excessive drainage volume, reducing the occurrence of corrugated pipe breakage due to excessive water flow in a single drainage pipe.

[0012] Preferably, the drainage pipe includes a corrugated pipe disposed between two impermeable layers. An embedded part is disposed between the two sides of the two impermeable layers. Both ends of the corrugated pipe are provided with an inner groove I. Both ends of the corrugated pipe are provided with a joint. A fastening bolt is disposed on the side of the joint away from the corrugated pipe. Both ends of the corrugated pipe are provided with an inner groove II at the top of the inner wall. A fixing rod is disposed in the inner groove II. A locking block is disposed on the side of the fixing rod. A rotating block is disposed at the end of the fixing rod near the inner wall of the corrugated pipe.

[0013] Preferably, the connector and the inner groove are adapted to each other, the inner groove is adapted to the fixing rod and the locking block, the number of fastening bolts is four times that of the connector, and they are distributed in a ring around the transverse center line of the connector.

[0014] Through the above technical solution, the connector and the inner groove are adapted to each other, the inner groove is adapted to the fixing rod and the locking block, the number of fastening bolts is four times that of the connector, and the design is a ring distribution about the transverse center line of the connector. The side of the corrugated pipe with the inner groove can be plugged into the connector. Then, the fixing rod and the locking block are placed in the inner groove, and the rotating block is rotated to lock the locking block into the inner groove. Finally, it is locked by fastening bolts. The corrugated pipe and the connector can be disassembled and installed. When a local component is damaged and needs to be repaired or replaced, only the local component needs to be repaired, which reduces the maintenance cost.

[0015] Preferably, the corrugated pipe is inclined at 2° towards the main drainage channel, the two ends of the corrugated pipe have large openings, and the middle part of the corrugated pipe is relatively narrow.

[0016] The above technical solution, by tilting the corrugated pipe 2° towards the main drainage channel, can improve drainage efficiency through gravity assistance. The design of large openings at both ends and a narrower middle section of the corrugated pipe utilizes the Venturi effect, which improves drainage efficiency and reduces water accumulation. Moreover, the structure does not require additional power and achieves the benefit of improved drainage efficiency through the structure itself, thus reducing costs.

[0017] Compared with the prior art, this utility model provides a drainage structure for outdoor landscape walkways that prevents water accumulation, and has the following beneficial effects:

[0018] 1. This waterproof outdoor landscape walkway drainage structure, through the design of multiple sets of drainage pipes, improves the structure's ability to drain and divert water simultaneously under extreme weather conditions such as heavy rain and excessive drainage volume. This reduces the possibility of a single drainage pipe breaking due to excessive water flow. The design of the corrugated pipes tilting towards the main drainage channel at a certain angle allows gravity to assist in improving drainage efficiency. The design of large openings at both ends of the corrugated pipes and a narrower middle section utilizes the Venturi effect, further enhancing drainage efficiency and reducing water accumulation. Moreover, this structure achieves the benefits of improved drainage efficiency solely through its structure, reducing costs, without requiring additional power.

[0019] 2. The drainage structure of this waterproof outdoor landscape walkway, through the matching of the joint and the inner groove, and the matching of the inner groove with the fixing rod and the locking block, realizes the detachable installation of the corrugated pipe and the joint. When a local component is damaged and needs to be repaired or replaced, only the local component needs to be repaired, thus reducing maintenance costs. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: As Figure 1-2 As shown, the present invention provides an outdoor landscape walkway drainage structure for preventing water accumulation, including two drainage ditch sidewalls 8 and a base layer 1 disposed between the two drainage ditch sidewalls 8. A cushion layer 2 is disposed on the top of the base layer 1. A stabilizing layer 3 is disposed on the side of the cushion layer 2 away from the base layer 1. A waterproof layer 4 is disposed on the side of the stabilizing layer 3 away from the cushion layer 2. An impermeable layer 5, a drainage pipe 6 and a main drainage channel 12 are disposed on the side of the waterproof layer 4 away from the stabilizing layer 3. A permeable surface layer 7 is disposed on the side of the impermeable layer 5, the drainage pipe 6 and the main drainage channel 12 away from the waterproof layer 4. A through groove 13 is provided at the connection between the drainage pipe 6 and the main drainage channel 12. A drainage groove 9 is provided on the top of the opposite surfaces of the two drainage ditch sidewalls 8. Limiting blocks 11 are provided on the top of both the drainage ditch sidewalls 8 and the permeable surface layer 7. A drainage cover 10 is provided between the top of the drainage ditch sidewalls 8 and the permeable surface layer 7.

[0028] Example 2: Figure 3-4 As shown, as an improvement to the previous embodiment, better drainage is achieved for the outdoor landscape walkway.

[0029] Specifically, the number of impermeable layers 5 is four times the number of base layers 1. The vertical cross-section of the impermeable layers 5 has an outward convex structure, and the impermeable layers 5 are symmetrically distributed about the transverse centerline of the embedded part 602. The advantage is that by making the number of impermeable layers 5 four times the number of base layers 1, the vertical cross-section of the impermeable layers 5 having an outward convex structure, and the transverse centerline of the impermeable layers 5 being symmetrically distributed about the transverse centerline of the embedded part 602, water seeping down from the permeable surface layer 7 is prevented from entering the main drainage channel 12, thus improving the drainage efficiency of the structure.

[0030] Specifically, the middle section of the sidewall of the drainage trough 9 and the side surface of the permeable surface layer 7 are both designed with an outward convex structure, and the top and bottom openings of the drainage trough 9 are larger than the middle section. The advantage is that by designing the middle section of the sidewall of the drainage trough 9 and the side surface of the permeable surface layer 7 with an outward convex structure, and the top and bottom openings of the drainage trough 9 being larger than the middle section, this structure utilizes the Venturi effect. This structure improves drainage efficiency; in heavy rain, the high-speed water flow can quickly drain accumulated water, reducing water accumulation. Furthermore, this structure requires no additional power; the improved drainage efficiency is achieved solely through the structure itself, thus reducing costs.

[0031] Specifically, the number of drainage pipes 6 is eight times the number of drainage ditch sidewalls 8, and the drainage pipes 6 are symmetrically distributed about the vertical centerline of the main drainage channel 12. The advantage is that by designing multiple sets of drainage pipes 6, the structure is better able to withstand extreme weather conditions such as heavy rain and excessive drainage volume. Multiple sets of drainage pipes 6 can simultaneously drain and divert water, reducing the likelihood of a single drainage pipe 6 breaking due to excessive water flow, which could cause the corrugated pipe 601 to break.

[0032] Specifically, the corrugated pipe 601 is inclined at 2° towards the main drainage channel 12, with large openings at both ends and a narrower middle section. The advantages are that the 2° inclination of the corrugated pipe 601 towards the main drainage channel 12 allows for gravity-assisted drainage, improving efficiency. The large openings at both ends and the narrower middle section utilize the Venturi effect, further enhancing drainage efficiency and reducing water accumulation. Moreover, this structure requires no additional power, achieving improved drainage efficiency solely through its design, thus reducing costs.

[0033] Example 3: Figure 3-4 As shown, as an improvement to the previous embodiment, in order to achieve detachable installation of the bellows 601 and the connector 603.

[0034] Specifically, the drainage pipe 6 includes a corrugated pipe 601, which is disposed between two impermeable layers 5. An embedded part 602 is disposed between the two sides of the two impermeable layers 5. Both ends of the corrugated pipe 601 are provided with an inner groove 604. Both ends of the corrugated pipe 601 are provided with a joint 603. The side of the joint 603 away from the corrugated pipe 601 is provided with a fastening bolt 605. The top of the inner wall of both ends of the corrugated pipe 601 is provided with an inner groove 606. A fixing rod 607 is disposed in the inner groove 606. A locking block 609 is disposed on the side of the fixing rod 607. A rotating block 608 is disposed at the end of the fixing rod 607 near the inner wall of the corrugated pipe 601.

[0035] Specifically, the connector 603 is adapted to the inner groove 604, the inner groove 606 is adapted to the fixing rod 607 and the locking block 609, and the number of fastening bolts 605 is four times that of the connector 603, and they are distributed in a ring around the transverse center line of the connector 603. The advantages are that the corrugated pipe 601 and the connector 603 are compatible with the inner groove 604, the inner groove 606 is compatible with the fixing rod 607 and the locking block 609, the number of fastening bolts 605 is four times that of the connector 603, and the design of the design of the connector 603 being distributed in a ring around the transverse center line is achieved. The side of the corrugated pipe 601 with the inner groove 604 can be inserted and connected to the connector 603. Then, the fixing rod 607 and the locking block 609 are placed in the inner groove 606, and the rotating block 608 is rotated to lock the locking block 609 into the inner groove 606. Finally, the fastening bolts 605 are used to lock it. The corrugated pipe 601 and the connector 603 can be disassembled and installed. When a local component is damaged and needs to be repaired or replaced, only the local component needs to be repaired, which reduces maintenance costs.

[0036] Working principle: In use, first connect one end of the corrugated pipe 601 to the main drainage channel 12. After connection, place the fixing rod 607 and locking block 609 into the inner groove 606. Then rotate the rotating block 608 to engage the locking block 609 in the inner groove 606. Finally, tighten the bolts 605. After tightening, the installation of one end of the corrugated pipe 601 to the main drainage channel 12 is complete. Repeat the above operation to install the other end of the corrugated pipe 601 to the embedded part 602 located between the two seepage-proof layers 5. After the entire corrugated pipe 601 is installed, Next, place the four corner alignment limit blocks 11 of the drain cover 10 to limit the drain cover 10, so that the drain cover 10 will not be displaced laterally even in extreme weather such as heavy rain. First, remove the drain cover 10. When the corrugated pipe 601 or some components are damaged and need repair, you can first loosen the fastening bolts 605, then rotate the rotating block 608, and remove the fixing rod 607, rotating block 608 and locking block 609 downwards. Finally, separate the corrugated pipe 601 from the embedded part 602 and the main drainage channel 12. This completes the disassembly of the structure, and the local components can be repaired or replaced.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
