[0013] (III) Beneficial Effects
[0014] Compared with the prior art, this utility model provides a water interception ditch with a water-sewage separation structure, which has the following beneficial effects:
[0015] High-efficiency water and wastewater separation: Through the separation mechanism, the separation holes on the separation plate can intercept larger debris such as leaves and mud carried in rainwater, so that rainwater and pollutants are initially separated, preventing debris from being directly discharged into natural water bodies, reducing environmental pollution, reducing the risk of drainage pipe blockage, and improving the drainage efficiency of intercepting ditches.
[0016] Stable and durable structure:
[0017] The stabilizing plate is embedded in the intercepting ditch body and is cast into one piece with the concrete, which enhances the structural strength of the intercepting ditch body, improves its resistance to deformation, and extends its service life.
[0018] The reinforcing ribs between the support plate and the inner wall of the intercepting ditch further strengthen the stability of the separation mechanism, ensuring that the separation plate maintains a reliable position during long-term use and preserves the effectiveness of the water-sewage separation function.
[0019] Excellent sealing and shock absorption performance: A 5 mm thick rubber block is installed under the cover plate to make it fit tightly against the main body of the drainage ditch. This not only provides a good seal to prevent rainwater leakage, but also provides shock absorption when vehicles run over it, reducing collision and wear between the cover plate and the main body of the drainage ditch and reducing noise.
[0020] Easy to clean and maintain: The separation plate is designed in a trapezoidal shape (narrow at the bottom and wide at the top), which makes it easy for the intercepted debris to accumulate on the top of the separation plate. The staff can open the cover regularly to clean the debris on the separation plate. The operation is convenient and the maintenance cost is low.
[0021] High load-bearing capacity: The cover plate is made of 50 mm thick Q235 steel plate, which has high strength and rigidity and can withstand the crushing of heavy vehicles. It is suitable for heavy-load driving environments such as highways and ensures driving safety. Attached Figure Description

[0027] 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.
[0028] Please see Figure 1-4 A water interception ditch with a water and sewage separation structure includes a water interception ditch body 1 and a cover plate 2. The water interception ditch body 1 is configured as a groove shape, and the cover plate 2 is disposed above the water interception ditch body 1. The water interception ditch body 1 is made of concrete and is provided with a separation mechanism.
[0029] The separation mechanism also includes a separation plate 3 and a support plate 4. The top of the cover plate 2 is provided with multiple sets of drainage holes 5. The inner walls of the separation plate 3 are provided with multiple sets of separation through holes 6. The left and right ends of the inner wall of the intercepting ditch body 1 are fixedly installed with support plates 4. The two sets of support plates 4 are used to support the two sides of the separation plate 3. The bottom of the cover plate 2 is placed tightly against the intercepting ditch body 1.
[0030] When this device is in use
[0031] Rainwater inflow: When rainwater falls onto the road surface, it flows into the intercepting ditch body 1 through multiple sets of drainage holes 5 at the top of the cover plate 2. The design of the drainage holes 5 can initially filter out some larger debris, such as large leaves.
[0032] Preliminary separation: After rainwater enters the intercepting ditch body 1, it flows through the separation plate 3 of the separation mechanism. The separation through holes 6 on the separation plate 3 allow rainwater to pass through, while intercepting larger debris such as leaves and mud carried in the rainwater above the separation plate 3, thus achieving preliminary separation of water and sewage.
[0033] Rainwater discharge: After initial separation, the rainwater enters the space of the intercepting ditch body 1 below the separation plate 3 through the separation through hole 6, and then flows along the slope of the intercepting ditch body 1 to the outlet, and is finally discharged into the designated drainage system or natural water body.
[0034] Debris accumulation: Debris intercepted by the separation plate 3 accumulates on top of the separation plate 3. Since the separation plate 3 has a trapezoidal structure (narrow at the bottom and wide at the top), the debris will naturally accumulate inside the separation plate 3 and will not affect the filtration of the water, making it easy to clean up later.
[0035] Maintenance and cleaning: Regularly open cover 2 (cover 2 is sealed to the intercepting ditch body 1 by rubber block 8; the clamping force of rubber block 8 must be removed before opening) to clean the debris accumulated on the separation plate 3, ensuring the smooth flow of the separation mechanism and the effectiveness of water and sewage separation. After cleaning, reinstall cover 2, ensuring that rubber block 8 fits tightly against the intercepting ditch body 1, restoring the intercepting ditch to its normal working condition.
[0036] In actual use, it was found that it was not convenient to improve the overall installation strength. In order to solve the above problem, this embodiment also includes a stabilizing plate 7. The stabilizing plate 7 fits the inner wall of the intercepting ditch body 1 and is embedded in the intercepting ditch body 1. The stabilizing plate 7 and the intercepting ditch body 1 are integrated by concrete pouring.
[0037] In actual use, it was found that it was not convenient to perform shock absorption. In order to solve the above problem, this embodiment also includes a rubber block 8, which is provided below the cover plate 2.
[0038] In actual use, it was found that it was not convenient to improve the support strength. In order to solve the above problem, this embodiment also includes reinforcing ribs 9. Multiple sets of reinforcing ribs 9 are provided between the support plate 4 and the inner wall of the intercepting ditch body 1.
[0039] In actual use, it was found that it was not convenient to intercept and place debris and to clean it regularly. In order to solve the above problems, in this embodiment, the separation plate 3 is set as a trapezoid, which is narrow at the bottom and wide at the top.
[0040] As a preferred embodiment of the above, the thickness of the rubber block 8 is set to five millimeters, and the cover plate 2 is made of a 50-millimeter-thick Q235 steel plate.
