Description

Technical Field

[0001] The invention relates to a drainage technology for urban vehicle roads, and in particular to a filtering and anti-clogging system for drainage ditches on urban vehicle roads. Background Art

[0002] The conventional method to improve the drainage capacity of sewers is mainly to expand the diameter of sewers. The transformation requires digging up the ground above all sewers, taking out the original pipes and burying or building pipes with larger diameters. The transformation cost is high, and the ground and underground facilities in the construction area need to be destroyed during the transformation process. It will also have a serious impact on nearby traffic during the construction period. The residual soil and machine noise generated during the construction process will also cause environmental pollution. Conventional transformation methods will cause comprehensive and serious damage and interference to the urban environment, transportation, and residents' lives. The long-term operation of drainage pipes in most cities in China has caused the pipes to age and there is no regular cleaning of the pipes. This leads to waterlogging on the road. Most cities have crude supporting drainage pump stations in each low-lying road and bridge to discharge the accumulated water. However, due to various reasons such as excessive water volume, debris blocking the pipes, or drainage pump failure maintenance, it takes a certain amount of time for the accumulated water to recede. In areas with serious waterlogging, the time for the water to recede is as short as 2 to 3 hours and as long as 1 to 2 days.

[0003] With the advancement of urbanization, the number of roads and buildings has increased rapidly, the surface has hardened over a large area, and the rainwater surface runoff coefficient has increased. In case of heavy rain, water will accumulate, and even waterlogging will occur, affecting urban traffic. In addition, with the increasing age of the road drainage network, the impact of human activities has intensified, such as paper scraps, fruit peels, glass, plastic, and fallen leaves constantly blocking the drainage ditch and causing water accumulation, which in turn breeds mosquitoes and even rots to form a foul odor, all of which have worsened the urban environmental sanitation. Summary of the invention

[0004] In view of this, the present invention provides an urban roadway drainage ditch filtering and anti-clogging system, which innovatively arranges an anti-clogging device at the bend of the drainage ditch, which can effectively solve the problem that the drainage ditch is easily blocked by garbage. At the same time, a basket is arranged in the debris storage box, which can facilitate the cleaning of garbage in the debris storage box and improve the cleaning efficiency.

[0005] To this end, the present invention provides an urban roadway drainage ditch filtering and anti-clogging system, which comprises: a roadway, a sidewalk and a drainage ditch, wherein the drainage ditch is arranged between the roadway and the sidewalk, and the roadway, the sidewalk and the drainage ditch are arranged side by side and in parallel, and an anti-clogging device is arranged at the bend of the drainage ditch, the anti-clogging device comprises a filtering component and a debris storage box, the opening of the debris storage box is arranged at the tangent of the drainage ditch bend, the filtering component is fixedly connected in the drainage ditch, and the filtering component is located on one side of the top of the debris storage box, the water in the drainage ditch carries part of the solid debris and flows into the bend, the filtering component blocks the solid debris outside the filtering component, and the debris will be carried by the water body into the debris storage box under the action of gravity and inertia.

[0006] Furthermore, the above feature is that a mounting groove is provided on the drainage ditch, and the filter component is installed in the mounting groove.

[0007] Furthermore, the above-mentioned filter component includes a fixing frame and a filter screen, the fixing frame is installed in the installation groove, and the filter screen is fixedly or detachably connected to the fixing frame.

[0008] Furthermore, an inclined angle is formed between the debris storage box and the drainage ditch.

[0009] Furthermore, a basket is provided in the debris storage box, and the basket is used to take out the solid debris in the debris storage box.

[0010] Furthermore, the debris storage box is provided with a plurality of drainage openings, and the plurality of drainage openings are evenly distributed on the debris storage box.

[0011] Furthermore, a gravel layer is provided at the bottom of the drainage ditch.

[0012] Furthermore, a plurality of seepage holes are arranged at the bottom of the drainage ditch, and the plurality of seepage holes are arranged equidistantly along the length direction of the drainage ditch, and the seepage holes extend into the gravel layer.

[0013] Furthermore, the diameter of the water seepage hole gradually increases downwards.

[0014] Furthermore, the height of the sidewalk is higher than that of the roadway.

[0015] In a filtering and anti-clogging system for urban roadway drainage ditch provided by the present invention, an anti-clogging device is arranged at the bend of the drainage ditch, which can effectively solve the problem that the drainage ditch is easily blocked by garbage. At the same time, a basket is arranged in the debris storage box, which can facilitate the cleaning of garbage in the debris storage box and improve the cleaning efficiency. Specifically, an anti-clogging device is arranged at the bend of the drainage ditch, and the anti-clogging device includes a filter net and a debris storage box. When the water body ( Figure 2 The solid arrow in the middle) carries some solid debris into the bend, and the filter mesh removes the solid debris ( Figure 2The debris (arrow in the middle dashed line) is blocked outside the mesh. Under the action of gravity and inertia, the debris will be carried by the water body and flow into the anti-blocking device in the same direction as the previous water body. When solids accumulate somewhere in the drainage ditch, they are cleaned by cleaning the solid debris in the storage box, thereby reducing the probability of drainage ditch blockage due to solid debris.

[0016] Secondly, in the urban roadway drainage ditch filtering and anti-clogging system provided by the present invention, a basket is innovatively arranged in the storage box, and the solid debris in the storage box can be cleaned through the basket, so there is no need to take out the debris storage box, which can reduce the cleaning difficulty and improve the cleaning efficiency.

[0028] In the urban roadway drainage ditch filtering and anti-clogging system provided by the present invention, an anti-clogging device is arranged at the bend of the drainage ditch, which can effectively solve the problem that the drainage ditch is easily blocked by garbage. At the same time, a basket is arranged in the debris storage box, which can facilitate the cleaning of the garbage in the debris storage box and improve the cleaning efficiency. Specifically, an anti-clogging device is arranged at the bend of the drainage ditch, and the anti-clogging device includes a filter screen and a debris storage box.
