[0004] But as green plants need to be exposed to the outside world, so in the use process, due to the influence of rainwater scouring and surface runoff, soil, household garbage and other sundries will accumulate in the drainage ditch, causing the drainage ditch to be blocked.

[0005] Therefore, a new scheme needs to be proposed to solve this problem. UTILITY MODEL CONTENT

[0006] In view of the deficiencies existing in the prior art, the purpose of the utility model is to provide an ecological drainage ditch, which can collect sundries and improve the drainage effect of the drainage ditch.

[0007] The above technical purpose of the utility model is realized by the following technical scheme: an ecological drainage ditch, comprising a base, two symmetrical slopes are arranged on the base, a soil retaining block is fixedly connected to the side wall of the slope, and a drainage channel is formed between the soil retaining blocks, a settlement groove is formed in the soil retaining block, and a plurality of water permeation holes are formed in the side wall of the settlement groove and communicated with the drainage channel.

[0008] By adopting the technical scheme, the slope is formed by planting soil, so that the constructors can plant vegetation on the slope, the root system of the vegetation can purify the suspended matters and impurities in the rainwater runoff, the rainwater and harmful substances in the air can be treated and absorbed, the retaining block can block the slope to ensure the stability of the slope, the problems such as soil loss and collapse of the slope caused by the erosion of the water flow in the drainage ditch in rainy days are avoided, the stability of the slope is improved, the rainwater can be stored in the slope by the cooperation of the retaining wall and the base, the rainwater can be used to nourish the vegetation, the energy-saving effect is achieved, in rainy days, the rainwater forms surface runoff on the slope and flows into the drainage ditch, so the fallen leaves, garbage, soil and other impurities on the slope are displaced along with the water flow, the impurities can be collected through the settling tank on the retaining block, so that the impurities are prevented from being accumulated in the drainage ditch to cause blockage, the drainage efficiency of the drainage ditch is improved, and the accumulated water in the settling tank can flow into the drainage ditch through the water seepage hole, so that the odor caused by the accumulation of the rainwater in the settling tank is avoided.

[0009] The utility model further sets up: the bottom surface of drainage ditch is inclined to one side.

[0010] By adopting the technical scheme, the water flow flows along the slope direction by the action of gravity, so that the speed and flow of the water flow are improved, and when the drainage ditch is installed, the height difference exists between the bottom surfaces of the adjacent two drainage ditches, so that the friction between the water flow and the drainage ditch is increased, the water flow flows more smoothly, and the drainage effect is improved.

[0011] The utility model further sets up: filter water layer is laid in the settling tank, and the height between the top of the filter water layer and the bottom of the settling tank is greater than the height between the water seepage hole and the bottom of the settling tank.

[0012] By adopting the technical scheme, the filter water layer is laid by sand and gravel, the liquid and impurities entering the settling tank are separated through the filter water layer, the solid-liquid separation effect is realized, the water filtering effect is achieved, and the accumulated water after filtration can be discharged into the drainage ditch through the water seepage hole, so that the accumulated water is prevented from being accumulated in the settling tank.

[0013] The utility model further sets up: the aperture of the water seepage hole close to the slope side is greater than the aperture of the water seepage hole close to the drainage ditch side.

[0014] By adopting the technical scheme, the water seepage hole has a large aperture on the side close to the slope, which can facilitate the drainage of accumulated water in the sedimentation tank and improve the drainage efficiency of the sedimentation tank, and the aperture on the side close to the drainage ditch is reduced, which can increase the pressure of water flow through the water seepage hole, thereby avoiding the accumulated water in the drainage ditch from seeping back into the sedimentation tank when the water flow in the drainage ditch is large, and affecting the solid-liquid separation of the sedimentation tank, and improving the practicability.

[0015] The utility model further sets up: the planting layer is paved on the side slope, and there are a plurality of planting cavities on the surface of the planting layer.

[0016] By adopting the technical scheme, since the side slope is formed by the accumulation of planting soil, when it rains, water droplets falling on the ground will gather on the ground, forming surface runoff, which will carry the dust and soil on the ground during the flow process, so planting vegetation on the side slope through the planting layer can block the erosion of water flow, avoid soil loss on the side slope due to the erosion of water flow, and improve the stability of the structure.

[0017] The utility model further sets up: the planting cavity is in honeycomb distribution.

[0018] By adopting the technical scheme, the honeycomb-shaped net structure can bear external forces from all directions, so that the resistance of the honeycomb structure to extrusion pressure is higher than that of any circular or square shape, which improves the stability of the overall structure of the drainage ditch, and the honeycomb structure can reduce the use of materials, thereby reducing the weight of the planting layer and avoiding settlement of the planting layer due to excessive pressure on the side slope, and improving the stability of the side slope structure.

[0019] The utility model further sets up: the planting layer is paved with lightweight bricks.

[0020] By adopting the technical scheme, the main components of lightweight bricks are lightweight aggregate and cement, etc., which have the advantages of light weight, etc., can reduce the working intensity of construction personnel, and can also reduce the pressure on the side slope during use, thereby avoiding settlement of the planting layer due to excessive weight of the planting layer, and improving the stability of the structure of the side slope.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. The side slope can be used for planting vegetation, and the root system of the vegetation can purify suspended solids and impurities in rainwater runoff, which plays a role in treating rainwater and absorbing harmful substances in the air.

[0023] 2. The soil retaining block can block the slope, ensure the stability of the slope, avoid soil loss and collapse of the slope due to the erosion of water flow in the drainage channel in rainy days, improve the stability of the slope, and accumulate rainwater in the slope through cooperation of the retaining wall and the base, so that the rainwater can be used to nourish vegetation, and the energy saving effect is achieved.

[0024] 3. The settlement groove formed in the soil retaining block can collect sundries, so as to avoid blockage of the drainage channel due to accumulation of sundries in the drainage channel, and improve the drainage efficiency of the drainage channel. BRIEF DESCRIPTION OF DRAWINGS

[0030] The utility model will be described in detail in combination with the drawings and examples.

[0031] An ecological drainage ditch, such as Figure 1As shown, including the base 1, the base 1 is laid with two symmetrical side slope 2, side slope 2 is formed by planting soil accumulation, so the construction personnel can plant vegetation on the side slope 2, through the root system of the vegetation can play a purifying effect on the suspended solids in the rainwater runoff, impurities, played a role in the treatment of rainwater and absorption of harmful substances in the air, the side wall of the side slope 2 is fixedly connected with the retaining block 3 and the retaining block 3 forms a drainage channel 4, through the retaining block 3 can play a blocking effect on the side slope 2, to ensure the stability of the side slope 2, avoid in rainy days, due to the scouring of the water flow in the drainage channel 4 leads to the soil loss of the side slope 2 collapse and other problems, improve the stability of the side slope 2, and through the retaining wall and the base 1 can also cooperate with the rainwater accumulation in the side slope 2, so it can use rainwater to nourish vegetation, played a role in energy saving, the retaining block 3 is provided with a settling tank 5, one side wall of the settling tank 5 is provided with a plurality of water permeable holes 6 communicated with the drainage channel 4, in rainy days, rainwater will be located on the side slope 2 to form surface runoff and flow into the drainage channel 4, so the fallen leaves, garbage, soil and other impurities located on the side slope 2 will be displaced with the flow of water, therefore, through the settling tank 5 provided on the retaining block 3 can collect the impurities, so as to avoid the impurities accumulated in the drainage channel 4 leads to blockage, played a role in improving the drainage efficiency of the drainage channel 4, and through the water permeable hole 6 can make the accumulated water in the settling tank 5 flow into the drainage channel 4, avoid the rainwater accumulation in the settling tank 5 leads to produce odor.

[0032] As shown in Figure 2 , the bottom of the drainage channel 4 is inclined to one side, by means of gravity, so that the water flow flows along the slope direction, thereby improving the speed and flow of the water flow, and when the drainage ditch is installed, there is a height difference between the bottoms of the two adjacent drainage channels 4, thereby increasing the friction between the water flow and the drainage channel 4, so that the water flow flows more smoothly, playing a role in improving the drainage effect.

[0033] As shown in Figure 3 , the settling tank 5 is provided with a filter layer 7, the height of the top end of the filter layer 7 from the bottom of the settling tank 5 is greater than the height of the water permeable hole 6 from the bottom of the settling tank 5, the filter layer 7 is made of sand, which can separate the liquid and impurities entering the settling tank 5, realizing the effect of solid-liquid separation, and playing a role in filtering water, and the filtered water can be discharged into the drainage channel 4 through the water permeable hole 6, avoiding the accumulation of water in the settling tank 5.

[0034] As shown in Figure 3 and Figure 4As shown, the aperture of the water seepage hole 6 near the side slope 2 is larger than the aperture near the drainage ditch 4, and the larger aperture near the side slope 2 can facilitate the drainage of accumulated water in the settlement tank 5, thereby improving the drainage efficiency of the settlement tank 5. Reducing the aperture of the water seepage hole 6 near the drainage ditch 4 can increase the pressure of the water flow through the water seepage hole 6, thereby preventing the accumulated water in the drainage ditch 4 from seeping back into the settlement tank 5 when the water flow in the drainage ditch 4 is large, which can affect the solid-liquid separation of the settlement tank 5. This design improves the practicality.

[0035] As shown in the Figure 3 The side slope 2 is covered with a planting layer 8, and the surface of the planting layer 8 has a plurality of planting cavities 9. Since the side slope 2 is formed by piling up planting soil, water droplets falling on the ground during rainy days will gather on the ground, forming surface runoff. The surface runoff will move with the dust and soil on the ground, so planting vegetation on the side slope 2 through the planting layer 8 can block the erosion of the water flow, preventing soil loss due to water erosion on the side slope 2, and improving the stability of the structure.

[0036] As shown in the Figure 3 The planting cavities 9 are arranged in a honeycomb pattern. The honeycomb pattern can withstand external forces from all directions, making the honeycomb structure more resistant to pressure than any circular or square shape. This design improves the stability of the overall structure of the drainage ditch and reduces the use of materials, thereby reducing the weight of the planting layer 8 and preventing the planting layer 8 from settling due to excessive pressure on the side slope 2, thereby improving the stability of the structure of the side slope 2.

[0037] As shown in the Figure 3 The planting layer 8 is made of lightweight bricks, which are mainly composed of lightweight aggregate and cement. Lightweight bricks have the advantages of light weight, which can reduce the work intensity of construction personnel and reduce the pressure on the side slope 2 during use, thereby preventing the planting layer 8 from settling due to excessive weight and improving the stability of the structure of the side slope 2.

[0039] When laying the drainage ditch, the base 1 is fixed in the pre-determined pit, and then the soil retaining blocks 3 are fixed on the base. At this time, the drainage ditch 4 for collecting rainwater is formed between the two soil retaining blocks 3. Then, the soil is laid between the soil retaining blocks 3 and the base 1 to form the side slope 2, and the planting layer 8 is laid on the surface of the side slope 2. The planting cavities 9 on the planting layer 8 are planted with vegetation. Finally, repeat the above operation and lay the sand and gravel in the settlement tank 5 to complete the laying of the drainage ditch.
