Description

Technical Field

[0001] The utility model relates to the technical field of road engineering, in particular to a road filter ditch storage structure. Background Art

[0002] Road filter ditch storage is a common urban rainwater management method that aims to reduce the impact and load of rainwater runoff on the urban drainage system. It is usually used in drainage ditches on both sides or in the center of the road to collect and temporarily store rainwater generated during rainfall. Road filter ditch storage has the following main functions: water filtration, storage, purification, and groundwater recharge.

[0003] In actual use, the stored water in the regulating and storage ditch usually seeps naturally into the ground or remains inside the regulating and storage ditch. The speed of natural infiltration is relatively slow. When heavy rain occurs, the water accumulation in the city will be particularly serious in a short period of time, the pressure on the city’s internal drainage system will increase dramatically, and the regulating and storage ditch will also be full in a short period of time. If the water flow inside the regulating and storage ditch is not drained out in time, it will easily lead to urban flooding.

[0004] Therefore, it is necessary to invent a road filter ditch storage structure to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a road filter ditch storage structure to solve the problem that when heavy rain occurs, water accumulation in the city will be particularly serious in a short period of time, the pressure of the city's internal drainage system will increase dramatically, and the storage ditch will also be full in a short period of time. If the water flow in the storage ditch is not led out in time, it is easy to cause urban waterlogging.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a road filter ditch storage structure, comprising a base soil layer, a pavement structure is paved on the upper side of the base soil layer, a water storage ditch body is arranged on the upper side of the base soil layer and located on the side of the pavement structure, an adjustment mechanism is arranged on the side of the water storage ditch body, the adjustment mechanism includes an equipment box, a first drainage pipe, a first connecting pipe, a second drainage pipe, a second connecting pipe, a water reservoir and a first seepage pipe, a water supply pipe, the water reservoir is located on the lower side of the water storage ditch body, and the equipment box is fixed on the side of the water storage ditch body.

[0007] By adopting the above technical solution, rainwater on the surface of the pavement structure is collected into the interior of the water storage ditch, and the water storage ditch filters and stores the inflowing rainwater. When the amount of rainwater is too large, the rainwater filtered inside the water storage ditch is transported to the interior of the reservoir through the first connecting pipe for storage, and the water source stored in the water storage ditch is drained to allow it to accept more new rainwater. At the same time, the water source is transported to the interior of the first seepage pipe through the second drainage pipe, thereby increasing the speed of rainwater infiltration, thereby reducing the pressure on the municipal drainage system and further increasing the water capacity of the water storage ditch itself.

[0008] Optionally, the first drainage pipe is fixedly connected to the rear side of the bottom wall of the equipment box, the lower end of the first drainage pipe extends to the inside of the water reservoir, and a first valve is installed at the upper end of the first drainage pipe.

[0009] By adopting the above technical solution, the first valve opens and closes the first drainage pipe.

[0010] Optionally, the first connecting pipe is fixedly connected to the side of the first drainage pipe, and the end of the first connecting pipe away from the first drainage pipe extends to a position near the lower side inside the water storage ditch body.

[0011] By adopting the above technical solution, the water source stored in the water storage ditch body enters the first drainage pipe through the first connecting pipe and is collected in the water tank.

[0012] Optionally, the second drainage pipe is fixedly connected to the front side of the bottom wall of the equipment box, the lower end of the second drainage pipe is fixedly connected to the first seepage pipe, the first seepage pipe is arranged on the side of the water reservoir, and the bottom of the first seepage pipe is fixedly connected to multiple groups of second seepage pipes, and the second seepage pipe is inserted into the deep of the base soil layer.

[0013] By adopting the above technical solution, the water on the surface of the water storage ditch body enters the interior of the first seepage pipe through the second drainage pipe. The first seepage pipe disperses the water to the interiors of multiple groups of second seepage pipes. Multiple groups of seepage holes are opened on the surface of the first seepage pipe and the second seepage pipe, so that rainwater can seep in quickly.

[0014] Optionally, the second connecting pipe is fixedly connected to the side of the second drainage pipe, and the second drainage pipe extends from one end of the second connecting pipe to a position near the upper side inside the water storage ditch body, and a second valve is installed at the upper end of the second connecting pipe.

[0015] By adopting the above technical solution, the second valve is used to open and close the second drainage pipe.

[0016] Optionally, a water pump is fixedly installed in the middle of the equipment box, the water inlet of the water pump is fixedly connected to the water inlet pipe, the lower end of the water inlet pipe extends to the interior of the water reservoir, the water outlet of the water pump is fixedly connected to the water outlet pipe, the left end of the water outlet pipe is fixedly connected to the water supply pipe, and the water supply pipe is laid on the upper side of the first seepage pipe.

[0017] By adopting the above technical solution, the water inside the reservoir is pumped into the water pipeline by a water pump for daily use in the city.

[0018] Optionally, the interior of the water storage ditch body is sequentially paved with a coarse sand water storage layer, a fine sand filtration layer, and a planting soil layer from bottom to top.

[0019] By adopting the above technical solution, the rainwater collected in the water storage ditch body is initially filtered through the surface vegetation, and then filtered through the planting soil layer and fine sand filter layer to improve the purity of the water.

[0020] Optionally, curbstones are fixedly connected between the pavement structure and the water storage ditch body, concrete water grates are laid between the curbstones, and drainage grooves are opened on the surface of the water storage ditch body at positions on the sides of the concrete water grates.

[0021] By adopting the above technical solution, rainwater on the surface of the road surface flows into the interior of the water storage ditch body after passing through the concrete grate, and at the same time the concrete grate blocks garbage on the road surface.

[0022] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0023] 1. The utility model opens the first valve and the second valve, so that the filtered water is transported to the interior of the water reservoir through the first drainage pipe for storage, and the water inside the water storage ditch body is quickly discharged, so that the water storage ditch body can accept more rainwater. At the same time, in the process of accepting rainwater, the surface water is transported to the interior of the first seepage pipe and the second seepage pipe through the second drainage pipe, so that the water quickly seeps into the groundwater layer, thereby reducing the drainage pressure of the drainage network, and quickly accepting rainwater on the road surface to avoid rainwater backflow and causing waterlogging. It solves the problem that when heavy rain occurs, the water accumulation in the city will be particularly serious in a short period of time, the pressure of the urban drainage system will increase dramatically, and the regulating ditch will also be full in a short time. If the water flow in the regulating ditch is not led out in time, it is easy to cause waterlogging in the city.

[0024] 2. The utility model collects filtered rainwater into an underground reservoir, thereby reducing water evaporation, allowing the water to remain for a longer time, retaining more water for daily use, and further improving the utilization efficiency of water resources.

[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] The utility model provides Figures 1 to 3 A road filter ditch storage structure shown includes a base soil layer 1, a pavement structure 11 is laid on the upper side of the base soil layer 1, a water storage ditch body 2 is arranged on the upper side of the base soil layer 1 and located on the side of the pavement structure 11, the interior of the water storage ditch body 2 is laid with a coarse sand water storage layer 24, a fine sand filter layer 23, and a planting soil layer 22 from bottom to top, a curbstone 12 is fixedly connected between the pavement structure 11 and the water storage ditch body 2, a concrete water grate 13 is laid between the curbstones 12, a drainage groove 21 is opened on the surface of the water storage ditch body 2 at a position on the side of the concrete water grate 13, and an adjustment mechanism is arranged on the side of the water storage ditch body 2, the adjustment mechanism includes an equipment box 3, a first drainage pipe 31, a first connecting pipe 32, a second drainage pipe 34, a second connecting pipe 35, a water reservoir 4 and a first seepage pipe 5, a water supply pipe 6, the water reservoir 4 is located on the lower side of the water storage ditch body 2, and the equipment box 3 is fixed on the side of the water storage ditch body 2.

[0035] Among them, rainwater is collected into the interior of the water storage ditch body 2 through the concrete water grate 13, and the rainwater is initially filtered by the vegetation on the surface of the planting soil layer 22, and then filtered step by step through the planting soil layer 22, the fine sand filter layer 23 and the coarse sand water storage layer 24, and stored in the interior of the water storage ditch body 2.

[0036] In addition, when heavy rain occurs, all the water inside the water storage ditch body 2 is discharged into the water storage tank 4 for storage in advance, and the inside of the water storage ditch body 2 is emptied to allow it to receive more rainwater. During the rain, rainwater gathers into the inside of the water storage ditch body 2, and after being filtered, it continues to gather into the inside of the water storage tank 4. At the same time, rainwater will flow into the inside of the first infiltration pipe 5, accelerating the infiltration speed of rainwater and avoiding the overflow of water inside the water storage ditch body 2, causing rainwater backflow and waterlogging.

[0037] See Figure 4 and Figure 5 The first drainage pipe 31 is fixedly connected to the rear side of the bottom wall of the equipment box 3, the lower end of the first drainage pipe 31 extends to the inside of the water reservoir 4, and a first valve 33 is installed at the upper end of the first drainage pipe 31. The first connecting pipe 32 is fixedly connected to the side of the first drainage pipe 31, and the end of the first connecting pipe 32 away from the first drainage pipe 31 extends to a position near the lower side of the water storage ditch body 2. The second drainage pipe 34 is fixedly connected to the front side of the bottom wall of the equipment box 3, and the lower end of the second drainage pipe 34 is fixedly connected to the first seepage pipe 5. The first seepage pipe 5 is arranged on the side of the water reservoir 4, and multiple groups of second seepage pipes 51 are fixedly connected to the bottom of the first seepage pipe 5. The second seepage pipe 51 is inserted into the deep of the base soil layer 1. The second connecting pipe 35 is fixedly connected to the side of the second drainage pipe 34, and the end of the second drainage pipe 34 away from the second connecting pipe 35 extends to a position near the upper side of the water storage ditch body 2. A second valve 36 is installed at the upper end of the second connecting pipe 35.

[0038] Specifically, the first valve 33 and the second valve 36 are opened in advance before the arrival of rain. At this time, the water inside the water storage ditch body 2 is collected into the water tank 4 through the first drainage pipe 31, and then the water inside the water storage ditch body 2 is drained. During the rain, the rainwater is filtered and continuously collected into the water tank 4. The surface rainwater will be collected into the first seepage pipe 5 through the second drainage pipe 34. The first seepage pipe 5 will then divert the water to the interior of multiple groups of second seepage pipes 51, so that the rainwater can quickly seep into the ground, thereby effectively preventing the water storage ditch body 2 from being full in a short time, so that the water storage ditch body 2 can continue to collect rainwater to avoid waterlogging.

[0039] See Figure 6A water pump 37 is fixedly installed in the middle of the equipment box 3, and the water inlet of the water pump 37 is fixedly connected to the water inlet pipe 38. The lower end of the water inlet pipe 38 extends to the inside of the water reservoir 4, and the water outlet of the water pump 37 is fixedly connected to the water outlet pipe 39. The left end of the water outlet pipe 39 is fixedly connected to the water pipe 6, and the water pipe 6 is laid on the upper side of the first seepage pipe 5.

[0040] At the same time, after the rain, the first valve 33 and the second valve 36 are closed to preserve a certain amount of water inside the water storage ditch body 2 for vegetation growth. During daily use, the rainwater collected in the water storage tank 4 is pumped into the water pipe 6 by the water pump 37 for daily use in the city, thereby improving the efficiency of water resource utilization.

[0041] Working principle of the present invention: In order to reduce the drainage pressure of the urban drainage network and avoid waterlogging, the rainwater is filtered and collected into the interior of the water storage tank 4, and the infiltration speed of the water body is increased through the first seepage pipe 5 and the second seepage pipe 51, so that the water body inside the water storage ditch body 2 is quickly emptied, so that it can accept more rainwater, thereby reducing the drainage pressure of the drainage network and avoiding waterlogging caused by road surface waterlogging.
