[0003] However, the existing water storage wells only have the basic water storage function, and do not have the function of regulating and filtering, which leads to problems such as waste of water resources and difficulty in regulation. By collecting rainwater, recycled water, surface water and other water resources and storing them in wells, additional equipment is required and manual control is required during the process of filtering them into the ground.

For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0022] Embodiment 1 Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the present embodiment provides a sponge city seepage regulation system, including a regulating well 10, a seepage well 20 and a water level monitor 30. The regulating well 10 is provided with a sewage pipeline system 101 for discharging sludge and sewage, a drainage pipeline system 102 for regulating water and an exhaust pipeline 103 for balancing air pressure from bottom to top, and one end of the exhaust pipeline 103 is arranged at the top of the regulating well 10; a filter connecting pipe 201 is arranged between the seepage well 20 and the regulating well 10, and multiple layers of filter materials 202 are arranged in the seepage well 20. The fineness of the filter material 202 near the water outlet along the water flow direction is greater than the fineness of the filter material 202 near the water inlet, that is, the filter material 202 is arranged from coarse to fine along the water flow direction, and the filter material particle size near the water outlet is smaller than the filter material particle size near the water inlet; the water level monitor 30 includes a first monitoring line 301 arranged in the regulating well 10 and a second monitoring line 302 arranged in the seepage well 20.

[0023] Specifically, the water level monitor 30 can be an ultrasonic level meter or a water level monitoring sensor or a water immersion sensor, such as the EM300-SLD / ZLD water immersion sensor, so that the water level height values ​​in the regulating well 10 and the seepage well 20 can be accurately obtained for corresponding control purposes.

[0024] When in use, rainwater or water dispatched from other water storage wells can be collected through the regulating storage well 10, that is, the regulating storage well 10 located at different positions can be connected through the water inlet pipe on the top of the regulating storage well 10, or the water in the accessory water tank can be introduced into the regulating storage well 10 through the water inlet pipe, thereby achieving the water storage purpose of the regulating storage well 10, that is, collecting the water resources in the accessories so as to perform corresponding management through the regulating storage well 10 and the seepage well 20.

[0025] When it is necessary to regulate and store water resources, operations will be performed according to the water level signal fed back by the water level monitor 30 to form water inlet and outlet in the regulating and storing well 10, and to transport water to the seepage well 20 or discharge sewage. For example, when the water level reaches the artificially set drainage level, drainage is performed or water is supplied to other regulating and storing wells 10 to ensure that the water resources in the regulating and storing well 10 meet the needs of regulation and storage. Similarly, when the water level in the regulating and storing well 10 reaches the artificially set seepage water level, the valve 1022 on the filter connecting pipe 201 will be opened (multiple valves 1022 can be set, such as gate valves and check valves, and the check valve is used to avoid backflow, while the gate valve is used to open or close the water inlet pipe), and the water in the regulating and storing well 10 will be introduced into the seepage well 20 for infiltration to supplement the groundwater source in the area where the regulating and storing well 10 is located. In order to ensure the water quality of the percolation water, the filter connecting pipe 201 will perform preliminary filtration and screening, and then filter again in the seepage well 20 through the filter material 202 designed layer by layer. The filter material 202 can be arranged from coarse to fine layer by layer to facilitate percolation and diffusion, such as a hierarchical structure or an annular hierarchical structure design, etc., to achieve multi-stage filtration. The filter material 202 can be one or more of quartz sand, gravel, anthracite, pebbles, manganese sand, magnetite filter material, fruit shell filter material, foam filter beads, porcelain sand filter material, ceramsite, garnet filter material, medical stone filter material, sponge iron filter material, activated alumina ball, zeolite filter material, volcanic rock filter material, granular activated carbon, fiber ball, fiber bundle filter material, comet fiber filter material, which can be used as needed.

[0026] In this way, multiple sponge city storage and infiltration systems are built in the city to achieve the transformation goal of sponge city construction in the city, promote the effect of green and sustainable development of the city, and achieve green infrastructure with the functions of "infiltration, retention, storage and purification". Combined with the comprehensive storage and drainage functions of the urban water system, it can reduce rainwater runoff, purify or infiltrate rainwater, and achieve the purpose of conserving groundwater or using it for municipal irrigation and ecological replenishment, so that rainwater resources can be effectively managed and utilized; at the same time, it can achieve the effects of "no water accumulation in light rain, no waterlogging in heavy rain, no black and smelly water, and relief of urban heat island", thereby increasing the elasticity and resilience of the city in responding to changes in the natural environment.

[0027] Furthermore, the top surface of the wellhead of the regulating and storage well is provided with a sunken ground, and the sunken ground includes a planting soil layer, a permeable membrane layer and an aquifer. Through the design of the sunken ground structure (the lower structure can be artificially modified and designed), rainwater that penetrates into the planting soil layer can be effectively collected, and then filtered and collected through the permeable membrane layer, and then infiltrates into the aquifer, and then flows into the regulating and storage well, achieving the effect of collecting rainwater. Of course, the water in the regulating and storage well can also be regulated and transported through other regulating and storage wells, forming an effective regulation and collection purpose.

[0028] like Figure 1 and Figure 4As shown, in this embodiment, the sewage pipe system 101 includes a sewage pump 1011 arranged on the bottom surface of the regulating storage well 10 and a sewage pipe 1012 connected to the output end of the sewage pump 1011; the inner bottom surface of the regulating storage well 10 is provided with an annular slide 104. The structure of the annular slide 104 can concentrate the sludge in the middle, which is convenient for the sewage pump to pump and discharge, avoids the sludge from accumulating in the corner, and improves practicality.

[0029] In this embodiment, the drainage pipe system 102 is provided with multiple groups, and the drainage pipe system 102 includes a drainage pump 1021 and a drainage pipe 1023 arranged on the output end of the drainage pump 1021, and at least one valve 1022 is arranged on the drainage pipe 1023; a placement rack 105 for placing the drainage pump 1021 is arranged in the middle of the regulating well 10.

[0030] Specifically, the distance between the drainage pump 1021 and the bottom of the regulating and storing well 10 can be raised by placing the rack 105, so that the drainage pump 1021 will not pump muddy water with sludge at the bottom, so as to ensure the service life of the drainage pump 1021, and at the same time will not affect the water quality of the regulating and storing water, and can be clearly distinguished from the water level of the sewage pump 1011. The use of multiple groups of drainage pipeline systems 102 can form multiple externally connected drainage pipes 1023 to meet different output requirements, such as connecting with other regulating and storing wells 10, or forming ground water pipes for use by fire-fighting facilities, etc., to improve practicality.

[0031] Furthermore, if Figure 1 As shown, in this embodiment, a pressure device and a plurality of first expansion deformation joints 1024 are also provided on the drainage pipe 1023. The expansion deformation joint is used to absorb the deformation caused by uneven settlement to protect the pipe from rupture and increase the service life of the pipe.

[0032] like Figure 1 and Figure 5 As shown, the seepage well 20 in this embodiment includes a coarse material filtering section 203 in the upper section and a seepage section 204 with multiple filter media 202 in the lower section. The bottom of the seepage well 20 is opened to form a water outlet; the filter connecting pipe 201 is arranged at the top of the seepage well 20 and forms a water inlet. It forms multiple levels of filtration with different coarseness and fineness, ensuring that the water source enters the groundwater after being filtered layer by layer, thus effectively ensuring the quality of the discharged water.

[0033] Furthermore, if Figure 1 and Figure 5As shown, in this embodiment, the multi-channel filter material 202 is arranged in layers from the inside to the outside; and the central filter material 202 is arranged in the same manner as the filler in the coarse material filter section 203. The fineness of the filter material 202 near the water outlet along the water flow direction is greater than the fineness of the filter material 202 near the water inlet. For example, the coarse material can be large pieces of coarse stone or gravel, the coarse and fine materials can be small pieces of coarse stone, zeolite or ceramsite, etc., and the fine material can be quartz sand. In this way, a multi-level filtration purpose from coarse to fine is formed from the inside to the outside to ensure multi-stage filtration of water resources and ensure the safety of discharged water quality.

[0034] like Figure 1 and Figure 2 As shown, in this embodiment, a flow control valve 2011 and a second expansion deformation joint 2012 are provided on the filter connecting pipe 201, and a filter membrane 2013 is provided on the port of the filter connecting pipe 201. The filter membrane 2013 can be provided on the ports at both ends of the filter connecting pipe 201. The opening of the valve 1022 can be controlled by the flow control valve 2011, so as to control the flow of the regulating well 10 into the seepage well 20, so as to achieve the purpose of flexible regulation of the water volume in the regulating well 10. The design of the filter membrane 2013 can achieve the first filtering effect on the water flowing into the regulating well 10; and the pipe port where the filter membrane is located is chamfered, so that pollutants can be effectively prevented from adhering to the surface of the filter membrane, and the filtering area can be increased at the same time. Further, the second expansion deformation joint 2012 is also an expansion deformation joint, which is used to absorb the deformation caused by uneven settlement to protect the pipeline from rupture and improve the service life of the pipeline.

[0035] like Figure 1 As shown, the present embodiment also includes a power control device 40 for providing electric energy, and the power control device 40 includes a photovoltaic panel 401, a battery 402 electrically connected to the photovoltaic panel 401, and a frame 403 for placing the photovoltaic panel 401 and the battery 402; the battery 402 is electrically connected with a circuit connector 404. Through the design of the photovoltaic panel 401 and the battery 402, solar energy can be used to generate electricity and store it for use in the electric energy of the sponge city's regulation and storage seepage system, thereby improving environmental protection performance. In order to facilitate electrical connection with a water pump or a detector, the circuit connector 404 (the circuit connector 404 can be an ATX24-pin interface, an ATX12V4-pin interface, an EPS12V4+4 / 8-pin interface, a PCI-E6-pin / 6+2-pin interface, a SATA power interface, or a D-type large 4-pin interface, etc., or a waterproof power universal connector) is used for connection to improve the convenience of operation.

[0036] Embodiment 2 like Figure 6As shown, this embodiment provides a method for regulating seepage in a sponge city. The regulating seepage system of a sponge city as recorded in the embodiment is used to perform the method for regulating seepage in a sponge city, including the following steps: S101. Power on.

[0037] S102. The warning water level, the regulating water level, the minimum seepage water level, the minimum drainage level and the sewage level are manually set in sequence from top to bottom according to the depth of the regulating well, and stored.

[0038] The system stores corresponding water level information according to the depth of the regulating and storage well, including warning water level, regulating and storage water level, minimum seepage water level, minimum drainage level and sewage level, so as to facilitate subsequent comparison and determine whether the corresponding operation can be performed, thereby improving practicality.

[0039] S103, obtain the water level information in the regulating well, compare the water level information with the water level in the set water level in turn, if it is higher than the sewage discharge level, it is qualified to discharge sewage and operate independently; if it is higher than the minimum drainage level, it is qualified to regulate the water source and operate independently; if it is higher than the minimum seepage water level, it is qualified to divert water to the seepage well for seepage and operate independently; if it is higher than the warning water level, send an early warning message to the external terminal.

[0040] Furthermore, during the settlement process through the seepage well, there is a settlement monitoring point (set at the top of the seepage well). Please refer to the following for specific settlement monitoring methods.

[0041] S104, obtaining water resource regulation information, and when conditions for regulating water sources are met, opening corresponding drainage pumps and valves to regulate water, and closing them after regulation is completed.

[0042] Only when the water level reaches or exceeds the corresponding set water level position, the required operations are available. For example, when the water level is higher than the minimum seepage water level, the sewage discharge, drainage and infiltration drainage operations can be performed independently; similarly, if it is higher than the storage water level, the storage operation can be performed; if it is between the sewage discharge level and the drainage level, only the sewage discharge operation can be performed to achieve the corresponding control. At the corresponding two minimum drainage levels and the minimum seepage water level, operations can be performed after adding a certain storage threshold to ensure the stable operation of storage, and the minimum drainage level and the minimum seepage water level form a warning water level warning effect, which is explained in detail below.

[0043] S105. When there is no regulation and storage information and the conditions for regulating and storing water sources are met, control the valve opening on the connecting pipe between the regulation and storage well and the seepage well to perform seepage.

[0044] When there is sufficient water in the regulating well and there is no regulation task, under the condition of infiltration, infiltration can be carried out through the infiltration well to replenish groundwater, and at the same time the amount of water in the regulating well can be regulated to form a flexible pipeline.

[0045] S106. If the water level reaches the warning level and there is no storage information, drainage and / or sewage discharge is carried out to control the water level in the storage well.

[0046] By draining and discharging sewage, the water level in the regulating well is lowered and properly discharged to ensure the safety of the water level in the regulating well and avoid excessive water level and water overflow. This creates a unique prevention effect. Of course, artificial regulation can also be used to solve the problem of water level being higher than the warning level, thus creating an artificial dispatching effect.

[0047] Furthermore, the steps of the method also include presetting a storage threshold and a preset infiltration threshold, and storing and retrieving them; obtaining water level information, and determining whether the water level in the water level information is higher than the water level of the sum of the preset storage threshold and the minimum drainage level; if so, water is adjusted until the water level in the storage well is lower than the minimum drainage level, and storage is stopped; obtaining infiltration information, and determining whether the water level of the infiltration information is higher than the water level of the sum of the preset infiltration threshold and the minimum seepage water level; if so, opening the valve for infiltration until the water level in the storage well is lower than the minimum seepage water level, and the infiltration is stopped.

[0048] According to the size of the regulating and storing well, preset regulating and storing thresholds and preset infiltration thresholds are set to ensure that the regulating and storing amount and infiltration amount are sufficient to avoid high frequency of equipment start and stop, which affects the service life. At the same time, the lowest drainage level and the lowest seepage water level are designed as warning water levels, and then the water level early warning function is used, so that when it is lower than the corresponding water level, the corresponding water pump is stopped. For example, if it is lower than the lowest drainage level, the drainage is stopped; if it is lower than the lowest seepage water level, the seepage is stopped. The purpose of having sufficient water sources for corresponding regulation and storage is achieved, and practicality is improved.

[0049] When performing seepage regulation, there are also seepage preconditions, namely, monitoring whether the settlement in the area where the regulating well is located is normal, and judging whether the pressure value in the regulating well is normal.

[0050] Specifically, settlement refers to the ground settlement of the soil layer around the sponge city's seepage system. For example, excessive groundwater extraction causes the water level to drop, and in the distribution area of ​​under-consolidated or semi-consolidated soil layers, the consolidation of the soil layer causes a large area of ​​ground subsidence. The process of water seepage will cause a certain disturbance to the underground. If the disturbance is too large, it will cause geological changes. That is, the infiltration process will cause the water content of the underground soil layer to increase. With the increase in water volume, the friction coefficient will decrease, which is easy to cause settlement. Therefore, it is necessary to monitor the settlement to ensure that the geology of the corresponding place is not damaged, to avoid damage to the geology or the occurrence of corresponding geological disasters.

[0051] In the case of detecting settlement, it can be monitored by a settlement meter, such as a magnetic settlement meter, model CJ-1B, to monitor the settlement of the seepage well area. Alternatively, a piezoresistive static level is used for monitoring, and a reference tank is installed at a relatively fixed point. When in use, the sensors are connected to the reference tank through a high-strength air pressure pipe. Each level is equipped with a high-precision silicon pressure sensor. The liquid medium is filled between the reference tank and the sensor. The pressure sensor in the level senses the pressure from the point to the liquid surface of the reference tank, and the pressure has a certain linear relationship with the wave surface height. If the pressure sensor senses a change in pressure, it means that the height difference between the point and the reference liquid surface has changed. According to the calibration linear table of the pressure change and the liquid surface height difference before leaving the factory, the microcontroller inside the static level can calculate the height difference change value. The root H=P / ρ*ɡ, ρ is the liquid density, H is the depth, P is the liquid pressure, and g is the gravity coefficient. The height from the measuring point to the reference point liquid surface to the sensor is calculated.

[0052] For the judgment of pressure value, a pressure detector, such as the SIN-PM800 wireless pressure sensor, can be used to monitor the pressure change during the underground disturbance (if there is no pressure change, the pressure change value is zero). The gas in the air will also be discharged during the infiltration process to obtain the exhaust volume value. Specifically, the pressure change value and the settlement change value can be preset. During the implementation process, the real-time settlement and pressure change can be measured by the instrument. When the real-time monitored value is less than the artificially set value (the artificially set value can be set according to the local situation, for example, it can be set to increase 20% as the interval value based on the monitored pressure value. When the interval value is met, infiltration can be performed), the infiltration condition is met; when it exceeds the set value, the precondition is not met, and the infiltration operation cannot be performed.

[0053] When the conditions for infiltration are met, the infiltration speed can be controlled by controlling the infiltration speed and / or controlling the valve opening to achieve the purpose of controlling the infiltration.

[0054] Furthermore, the design of the filter material in this embodiment, the layered design from inside to outside, and the corresponding increase in fineness, have good support and can prevent sedimentation.

[0055] In the above, the change in water volume can be calculated by the water level change and the known specifications of the well; that is, the time t is calculated by the cross-section S of the well through the water level change △h, so as to obtain the water volume, that is, the flow rate.

[0056] When the inflow rate is 0, only the flow control valve of the seepage is opened. Under the change of water level within a certain period of time, the seepage rate under different openings can be obtained. In the initial state, the seepage rate under the flow control valve with different openings can be determined in this way as Vs, and the seepage time is t S .

[0057] Displacement Qp = Vs × t S .

[0058] When the water inflow is 0 and only the drainage pump is turned on, the drainage volume can be obtained by changing the water level within a certain period of time, and the drainage speed can be obtained as Vp; the seepage time is t p .

[0059] Displacement Qp=Vp×t p .

[0060] When the water inlet flow is 0 and only the sewage pump is turned on, the sewage discharge volume can be obtained by the change of water level within a certain period of time, and the sewage discharge speed can be obtained as Vw; the seepage time is t w .

[0061] Discharge volume Qw=Vw×t w .

[0062] The water flow rate in the time period t is Qj: the water level change in the time period t is △h, the cross-sectional area of ​​the well is S, and the operation time of the storage seepage system in the time period t is t S , the operation time of the sewage pipeline system in the time period t is t w , the operation time of the drainage pipeline system in the time period t is t p .

[0063] Water inflow Qj=△h×S+Vs×t S +Vw×t w +Vp×t p .

[0064] Through periodic parameter calibration, Vs, Vp, and Vw are calibrated to calculate the amount of water stored, the amount of water seeping underground, and the amount of sewage discharged. The groundwater level is monitored through the monitoring line in the seepage well. The time parameters are automatically counted when the system is running, and used as a reference for the storage and regulation plan. The trend and trend of water volume are judged through the way of data collection and change, forming an accurate storage and regulation effect.
