Description

Technical Field

[0001] This utility model relates to the field of highway engineering technology, specifically to an ecological roadside ditch with sponge city drainage facilities. Background Technology

[0002] Side ditches refer to the water ditches set up on both sides of the roadbed in highway engineering to collect and drain water from the road surface, shoulders and slopes. Side ditches are set up in excavated sections and embankment sections where the fill height is less than the depth of the side ditch. They can be divided into L-shaped, trapezoidal, saucer-shaped, triangular, rectangular or U-shaped side ditches, and can also be divided into open ditches and covered ditches. They are mostly made of stone blocks and can be combined with the curb stones to form a whole.

[0003] Currently, the application of sponge city in road engineering is mainly concentrated in pedestrian walkways in parks and green spaces, using permeable pavement structures. Its application in municipal roads is relatively rare. During road operation, a lot of garbage is generated on the road surface. When it rains, the garbage will flow into the ecological ditches on both sides of the road with the rainwater, causing water pollution. At the same time, the water resources cannot be recycled and reused, resulting in the waste of water resources. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an ecological roadside ditch with sponge city drainage facilities, which has advantages such as water purification and recycling. It solves the problem that during road operation, a lot of garbage is generated on the road surface, and during rainfall, the garbage flows into the ecological roadside ditch with the rainwater, causing water pollution. At the same time, the water resources cannot be recycled and reused, resulting in water waste.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ecological ditch for urban roads with sponge city drainage facilities, including a foundation, a slope on the left side of the foundation, a ditch body located inside the foundation on the right side of the slope, and an ecological mechanism inside the ditch body.

[0006] The ecological structure includes a top cover, a second screen located inside the ditch body at the bottom of the top cover, a pebble layer at the bottom of the second screen, a fine sand layer at the bottom of the pebble layer, a water level sensor on the left inner wall of the ditch body, a water collection tank at the bottom of the ditch body, a central pipe connecting the top of the water collection tank to the bottom of the ditch body, a solenoid valve on the outer surface of the central pipe, a water pump on the right side of the slope, and an outlet pipe connecting the water pump to the water collection tank.

[0007] Furthermore, a soil planting layer is provided on the outer surface of the slope, and a first screen is provided on both the front and back sides of the soil planting layer at the top of the foundation. A baffle is provided between the opposite side of the two first screens and the soil planting layer.

[0008] Furthermore, each of the first screens has a receiving cavity at its bottom, and a drainage pipe located at the top of the second screen is connected to the right side of the receiving cavity. The receiving cavity is configured to be higher on the left and lower on the right.

[0009] Furthermore, the top cover is adapted to the side ditch body, and the outer surface of the top cover is uniformly provided with flow holes. A conduit is provided on the right side of the side ditch body, and a solenoid valve is provided on the outer surface of the conduit.

[0010] Furthermore, both the left and right sides of the top cover are provided with edge flat layers located at the top of the foundation, and the water pump is fixedly installed on the left edge flat layer.

[0011] Furthermore, the output terminal of the water level sensor is electrically connected to the input terminals of the solenoid valve and the water pump.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] This urban roadside ecological ditch, equipped with sponge city drainage facilities, features a soil planting layer on the slope, facilitating planting and greening. A first screen intercepts residual debris on the foundation during the rainy season, allowing rainwater to flow into a receiving chamber. A baffle between the soil planting layer and the first screen prevents soil from falling onto the screen. Rainwater then flows into the ditch body through a drainage pipe. Inside, it undergoes secondary filtration through a second screen, followed by purification through a pebble and fine sand layer before flowing into the ditch itself. When the water level reaches a certain depth, a water level sensor sends a signal to a solenoid valve, which opens, allowing water to flow into a collection tank through a central pipe. Inside, when water needs to be extracted from the collection tank for reuse, the water is drawn up through the outlet pipe by the water pump. When the foundation is dry and needs moisturizing, the solenoid valve is opened, and the water in the ditch body is discharged through the conduit. By setting up a first screen and a receiving cavity, the amount of rainwater collected is increased to a greater extent, reducing water waste. By setting up a top cover, pedestrians are prevented from falling in, avoiding danger, and garbage in the rainwater is intercepted. By setting up an ecological mechanism, the rainwater is filtered and purified before being pumped up for reuse. This solves the problem that during road operation, a lot of garbage is generated on the road surface, and when it rains, the garbage flows into the ecological ditches on both sides of the road with the rainwater, causing water pollution and the inability to recycle water resources, resulting in water waste.

Detailed Implementation

[0018] 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.

[0019] Please see Figure 1-3 This embodiment of an ecological roadside ditch with sponge city drainage facilities includes a foundation 1, a slope 2 on the left side of the foundation 1, a soil planting layer 3 on the outer surface of the slope 2 to facilitate plant planting, a first screen 4 on the top of the foundation 1 on both the front and back sides of the soil planting layer 3 to facilitate the filtration of garbage in rainwater, a receiving cavity 6 at the bottom of the first screen 4, rainwater enters the receiving cavity 6 after passing through the first screen 4, a drainage pipe 8 on the top of the second screen 702 is connected to the right side of the receiving cavity 6, water in the receiving cavity 6 enters the interior of the ditch body 5 through the drainage pipe 8, the ditch body 5 is located inside the foundation 1 on the right side of the slope 2, and an ecological mechanism 7 is installed inside the ditch body 5.

[0020] The ecological structure 7 includes a top cover 701, with evenly spaced flow holes inside. The top cover 701 serves two purposes: firstly, it prevents pedestrians from falling in, avoiding danger; secondly, it intercepts debris in rainwater. At the bottom of the top cover 701 is a second screen 702 located inside the ditch body 5. Below the second screen 702 is a pebble layer 703, and below the pebble layer 703 is a fine sand layer 704. The inclusion of the second screen 702, pebble layer 703, and fine sand layer 704 facilitates the filtration and purification of rainwater for reuse. A conduit is located on the right side of the ditch body 5, with a solenoid valve on its outer surface. When the foundation 1 is dry and requires irrigation, the solenoid valve opens, allowing water in the ditch body 5 to flow out through the conduit. A water level sensor 705 is installed on the left inner wall of the body 5. The water level sensor 705 is electrically connected to an external controller. A water collection tank 706 is installed at the bottom of the body 5. A central pipe 707 is connected between the top of the water collection tank 706 and the bottom of the body 5. A solenoid valve 708 is installed on the outer surface of the central pipe 707. When the water in the body 5 reaches a certain height, the water level sensor 705 transmits a signal to the solenoid valve 708. Then the water in the body 5 flows into the water collection tank 706 through the central pipe 707. A water pump 709 is installed on the right side of the slope 2. A water outlet pipe 710 is connected between the water pump 709 and the water collection tank 706. When it is necessary to extract the water in the water collection tank 706 for secondary use, the water pump 709 extracts the water in the water collection tank 706 through the water outlet pipe 710.

[0021] In summary, this urban road ecological ditch with sponge city drainage facilities facilitates planting and greening by setting a soil planting layer 3 on the slope 2. During the rainy season, rainwater is intercepted by a first screen 4, which traps residual garbage on the foundation 1. The rainwater then flows into the receiving cavity 6. A baffle between the soil planting layer 3 and the first screen 4 prevents soil from falling onto the first screen 4. Rainwater in the receiving cavity 6 enters the ditch body 5 through the diversion pipe 8. Upon entering the ditch body 5, it undergoes secondary filtration by a second screen 702, and then purification by a pebble layer 703 and a fine sand layer 704 before flowing into the interior of the ditch body 5. When the water in the ditch body 5 accumulates to a certain depth, a water level sensor 705 transmits a signal to a solenoid valve 708, which opens, allowing the water in the ditch body 5 to flow through a centralized... Water flows into the collection tank 706 through pipe 707. When water needs to be extracted from the collection tank 706 for reuse, the water is drawn up through the outlet pipe 710 by the water pump 709. When the foundation 1 is dry and needs moisturizing, the water in the side ditch body 5 is discharged through the conduit when the solenoid valve is opened. By setting the first screen 4 and the receiving cavity 6, the amount of rainwater collected is increased to a greater extent, reducing the waste of water resources. By setting the top cover 701, on the one hand, pedestrians are prevented from falling in, avoiding danger, and on the other hand, garbage in the rainwater can be intercepted. By setting the ecological mechanism 7, the rainwater is filtered and purified, and then pumped up by the water pump 709 for reuse. This solves the problem that during road operation, a lot of garbage is generated on the road surface, and when it rains, the garbage will flow into the ecological side ditches on both sides of the road with the rainwater, causing water pollution and the inability to recycle water resources, resulting in the waste of water resources.
