[0002] In the process of urban development, a large number of hard pavement changes the original ecological background and hydrological characteristics, rainfall cannot be infiltrated in time, forming surface runoff, and the traditional urban drainage system is difficult to adapt to the runoff peak formed by heavy rain, eventually resulting in urban waterlogging. Therefore, it is necessary to strengthen the natural permeation of urban surface, and the permeation needs to be placed in the first place to alleviate the problem of urban waterlogging. Solving the problem of permeation can help reduce the surface runoff of cement ground and pavement into the pipe network, on the other hand, it can conserve groundwater, supplement the deficiency of groundwater, and also purify water quality through soil and improve urban microclimate.
[0003] In the construction of sponge city, drainage members such as infiltration wells are often used to enhance the water permeability of the ground. The existing infiltration well core column body is mostly made of concrete pouring and gravel, and its permeation mechanism mainly relies on the flow path formed by the gap of the filler. Its permeation to the surrounding soil completely depends on the permeability of the soil, and after a long time of use, soil particles may enter the gap due to seepage, causing the core column body to be blocked, eventually reducing its permeability. This is more obvious in areas with frequent rain and poor soil permeability. SUMMARY

[0008] Further, the distance between the bottom end of the anode electrode rod and the bottom end of the coarse aggregate filter core is 0-10 cm, and the distance between the top end of the anode electrode rod and the top end of the coarse aggregate filter core is 0-20 cm.
[0009] Further, the distance between the top end of the anode electrode rod and the top end of the coarse aggregate filter core is 15-20 cm.
[0010] Further, the diameter of the anode electrode rod is 2-4 cm.

[0028] To further understand the content, features, and effects of this invention, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:
[0029] like Figures 1 to 4 As shown, this embodiment discloses an electroosmosis enhanced permeation core column, including a coarse aggregate filter element 1, an electrode rod 2, a sealing cap 3, and a wire 4.
[0030] The coarse aggregate filter element 1 is a cylindrical structure made of permeable concrete, typically with a diameter of 8–10 cm and a length of 100–140 cm. The permeable concrete is made primarily of aggregates with a single particle size distribution of 15–30 mm.
[0031] The anode electrode stick 2 is arranged at the central axis of the coarse aggregate filter core 1, the distance between the bottom end of the anode electrode stick 2 and the bottom end of the coarse aggregate filter core 1 is 0-10 cm, and the distance between the top end of the anode electrode stick 2 and the top end of the coarse aggregate filter core 1 is 0-20 cm. Preferably, the distance between the top end of the anode electrode stick 2 and the top end of the coarse aggregate filter core 1 is 15-20 cm, because the upper soil has a large permeation area and is affected by water pressure, and the saturation of the soil after water storage is higher than that of the lower soil, so that the anode electrode stick 2 is arranged in the middle and lower parts of the coarse aggregate filter core 1, which can reduce resource waste.
[0032] The diameter of the anode electrode stick 2 is 2-4 cm, and a too small diameter may not be able to achieve a good electro-osmotic effect, and a too large diameter may not meet the required material hardness and may also cause resource waste.
[0033] The material of the anode electrode stick 2 can be selected from graphite electrodes, conductive plastics, and corrosion-resistant alloy materials, and has the characteristics of good conductivity and corrosion resistance.
[0034] The sealing cap 3 is made of an insulating material and is used to seal the connection between the anode electrode stick 2 and the wire 4 to prevent the anode electrode stick 2 from being corroded.
[0035] The sealing cap 3 is a cylindrical structure with an open lower part and is composed of a top plate and a cylinder wall. A circular through hole is formed in the center of the top plate of the sealing cap 3, and a rubber ring 31 is fixed in the circular through hole. The inner diameter of the rubber ring 31 matches the diameter of the wire 4, so that the wire 4 can pass through the rubber ring 31 and be sealed, preventing water from entering the gap between the sealing cap 3 and the wire 4, thereby protecting the effective connection between the wire 4 and the anode electrode stick 2. Four hollow elastic pieces 32 are arranged on the inner side of the cylinder wall of the sealing cap 3, which can tightly fix the sealing cap 3 and the anode electrode stick 2, and ensure that the connection between the wire 4 and the anode electrode stick 2 is not damaged.
[0036] The wire 4 is connected to the top of the anode electrode stick 2 and is led out from above the coarse aggregate filter core 1, and is used to be connected to the anode of the power supply.
[0037] The preparation process of the electro-osmotic reinforced permeation core column is as follows:
[0038] 1) First, use the mold of the coarse aggregate filter core 1 to pour and reserve the installation position of the anode electrode stick 2 in the middle;
[0039] 2) After the coarse aggregate permeation filter core 1 is initially cured, the electrode stick 2, the sealing cap 3 and the wire 4 are assembled, then poured and fixed, and then cured;
[0040] 3) After the curing is completed, the mold is removed to obtain the electro-osmotic reinforced permeation core column 5.
[0041] According to the above description, the electro-osmotic reinforced permeation core column of the application is convenient to operate, durable, effectively strengthens the permeation speed of the core column, shortens the water seepage time of the core column, and can increase or decrease the voltage according to the water storage condition, thereby reducing energy waste.
[0042] The electro-osmotic reinforced permeation core column 5 is used to form an electro-osmotic reinforced permeation and drainage structure, which comprises a plurality of electro-osmotic reinforced permeation core columns 5 and a plurality of cathode electrode rods 6. The electro-osmotic reinforced permeation core columns 5 and the cathode electrode rods 6 are arranged in an array and are embedded in the soil of the sponge construction area, and the electro-osmotic reinforced permeation core columns 5 and the cathode electrode rods 6 are arranged in an alternating and spaced manner. The electro-osmotic reinforced permeation core column 5 is connected to the anode of the power supply through the wire 4, and the cathode electrode rod 6 is connected to the cathode of the power supply. After rainfall and water storage, the power supply is turned on, and the appropriate voltage can be selected according to the size of the rainwater and the water storage condition.
[0043] As a preferred embodiment, the cathode electrode rods 6 are arranged around the electro-osmotic reinforced permeation core columns 5 according to the vertices of a polygon. For example, as shown in Figure 6 , the first arrangement mode can be that the electro-osmotic reinforced permeation core columns 5 are located at the center of a square, and the cathode electrode rods 6 are respectively located at the vertices of the square around the electro-osmotic reinforced permeation core columns 5. As shown in Figure 7 , the second arrangement mode can be that the electro-osmotic reinforced permeation core columns 5 are located at the center of a rhombus, and the cathode electrode rods 6 are respectively located at the vertices of the rhombus around the electro-osmotic reinforced permeation core columns 5. As shown in Figure 8 , the third arrangement mode can be that the electro-osmotic reinforced permeation core columns 5 are located at the center of a regular hexagon, and the cathode electrode rods 6 are respectively located at the vertices of the regular hexagon around the electro-osmotic reinforced permeation core columns 5.
[0044] The electro-osmotic reinforced permeation and drainage structure of the application makes full use of the cathode electrode rods 6 through the interaction between the plurality of cathode electrode rods 6 and the plurality of electro-osmotic reinforced permeation core columns 5. In theory, the more the number of sides of the polygon formed by the permeation and drainage structure, the better the electro-osmotic effect, and the better the diffusion effect of water to the surrounding area by electro-osmosis. However, the specific arrangement mode needs to be determined according to the average water storage amount that can be caused by the local conditions and the permeability of the construction area soil, so as to avoid poor permeation effect or resource waste.
[0045] Although the preferred embodiments of the application are described above in combination with the drawings, the application is not limited to the specific embodiments described above, which are only illustrative and not restrictive. Those skilled in the art can make many specific changes to the embodiments under the inspiration of the application without departing from the purpose of the application and the scope protected by the claims, and these all belong to the protection scope of the application.
