[0059] The embodiment provides a recharge and dredging system for groundwater recharge engineering in civil engineering to eliminate adverse effects of surrounding geological environment caused by foundation pit dewatering and simultaneously plays a role of saving and protecting groundwater resources.

[0060] During the recharge process, groundwater needs to be supplemented to the underground confined aquifer, so a recharge well penetrating into the underground confined aquifer is punched, and recharge water is filled into the recharge well. Since the underground confined aquifer contains a large amount of silt, a large amount of oxide precipitate, fine silt and foam will appear at the well bottom after the recharge water is filled into the recharge well for a period of time, which will cause blockage of the recharge pipeline, and will not only affect the progress of the recharge project but also cause damage to the recharge equipment and other risks. Therefore, when the well bottom appears to block the recharge pipeline, dredging treatment needs to be performed on the well bottom in time to ensure normal operation of the recharge work.

[0061] The recharge well of the prior art is usually a columnar well punched at a predetermined site. In this way, during the punching process, the recharge well is subjected to longitudinal load and simultaneously expands and deforms laterally due to the pressure of the drilling machine, so that the size of the well bottom is greater than the size of the well mouth, which is not conducive to the progress of the dredging work.

[0062] To solve the above problems, as shown in Figure 1 The recharge well 100 of the embodiment includes two layers of inner and outer layers, wherein the inner layer 120 is located at the center of the outer layer 110, and recharge water penetrates into the inner layer 120 to supplement groundwater. The outer layer 110 not only can withstand the pressure of the surrounding soil layer to avoid damage of the inner layer 120 caused by excessive pressure of the surrounding soil layer, but also can form a hoop effect on the inner layer 120 to constrain the inner layer 120 from laterally deforming when subjected to longitudinal pressure, so that the diameter of the inner layer 120 is relatively uniform, and the structural stability of the inner layer 120 is ensured, thereby facilitating the progress of the dredging work.

[0063] Further, the interval between the inner layer 120 and the outer layer 110 is 1 m, and the distance of 1 m not only can meet the processing requirement of the inner layer 120, but also can better ensure the restraining force of the outer layer 110 on the inner layer 120, so that the structure of the recharge well 100 is more stable.

[0064] As an optional solution, as shown in Figures 2 to 4 The recharge well 100 further includes a well cover 130, and the well cover 130 can block or open the well mouth of the inner layer 120. When the recharge work or the dredging work is performed, the well cover 130 needs to be covered to the well mouth to block the well mouth to avoid solid pollutants from the outside into the inner layer 120, thereby avoiding affecting the recharge work or the dredging work.

[0065] In the prior art, when the recharge well is recharged, the groundwater level is usually observed manually, and the recharge is manually performed according to the groundwater level drop. The recharge water quantity cannot be accurately controlled, and the phenomena of untimely recharge and over-recharge are prone to occur.

[0066] To solve the above problems, as shown in Figure 2 The present embodiment provides a recharge device 200 which can inject recharge water into the inner layer 120 of the recharge well 100 and display the flow rate of the recharge water to avoid the occurrence of untimely recharge and over-recharge.

[0067] Specifically, as shown in Figure 2 The recharge device 200 includes a pressure tank 220, a recharge pipe 260, an electric switch 250, and a first electromagnetic flowmeter 240. The pressure tank 220 is internally provided with recharge water. One end of the recharge pipe 260 is connected to the pressure tank 220, and the other end extends into the inner layer 120 through the well lid 130. The electric switch 250 can block or open the recharge pipe 260. When the electric switch 250 is opened, the recharge water in the pressure tank 220 can flow into the inner layer 120 through the recharge pipe 260. When the electric switch 250 is closed, the electric switch 250 can block the recharge pipe 260 to prevent the recharge water from flowing out of the pressure tank 220 into the inner layer 120. The first electromagnetic flowmeter 240 is arranged on the recharge pipe 260. When the electric switch 250 is opened to inject recharge water into the recharge well 100, the flow rate of the recharge water flowing through the recharge pipe 260 can be displayed, so that the operator can well control the water quantity of the recharge water injected into the recharge well 100, and the occurrence of untimely recharge and over-recharge can be avoided.

[0068] Further, the first electromagnetic flowmeter 240 is located upstream of the electric switch 250, and the recharge water quantity at the electric switch 250 is relatively sufficient, and the measurement is relatively accurate.

[0069] Further, when the recharge well 100 is recharged, the pressure in the pressure tank 220 needs to be measured to make the recharge water more smoothly and efficiently injected into the recharge well 100. To control the pressure in the pressure tank 220, as shown in Figure 2 The pressure tank 220 includes a tank body 226, a third pressure gauge 221, an exhaust valve 223, and a pressure pump 230. The third pressure gauge 221 and the exhaust valve 223 are arranged on the tank body 226, and the pressure pump 230 is arranged on the recharge pipe 260. The third pressure gauge 221 can measure the pressure in the tank body 226. When the pressure value in the tank body 226 is too large, the exhaust valve 223 is opened to release the pressure in the tank body 226. When the pressure value in the tank body 226 is too small, the pressure of the recharge water is small, and the recharge efficiency is affected. The pressure pump 230 can be used to pressurize the recharge water to improve the recharge efficiency.

[0070] Further, in order to ensure that there is enough recharge water in the pressure tank 220 to meet the replenishment of groundwater, as shown in Figure 2 The pressure tank 220 also includes a water level gauge 224 arranged on the tank body 226. Before the recharge device 200 is used to recharge the recharge well 100, the amount of recharge water in the tank body 226 can be known through the display of the water level gauge 224. When the amount of recharge water is insufficient, recharge water can be input into the tank body 226 in time. When the amount of recharge water is sufficient, the recharge device 200 can be directly used.

[0071] As an optional solution, as shown in Figure 2 The pressure tank 220 also includes a first roller 225 rotatably arranged on the tank body 226 and abutting against the workbench surface, so as to facilitate the movement of the recharge device 200 and save manpower, material resources and time cost.

[0072] When the recharge well bottom needs to be dredged during the recharge process, the prior art often uses a suction pipe 320 with one end extending into the recharge well bottom and the other end being communicated with a suction pump. The suction pump generates suction force on the mixture at the well bottom to suck out the mixture. However, the solid substances in the mixture often deposit at the bottom. Most of the substances sucked up by the suction pump are still groundwater. The dredging effect is poor.

[0073] To solve the above problems, as shown in Figure 3 The embodiment also provides a dredging device 300. The dredging device 300 includes an inflation pipe 301 and a suction pipe 320. The free ends of the inflation pipe 301 and the suction pipe 320 extend into the bottom of the inner layer 120 through the well cover 130. The dredging device 300 can provide blowing force for the inflation pipe 301 and suction force for the suction pipe 320. The inflation pipe 301 can inflate the well bottom to blow up the dirt at the well bottom to make the well water into sewage. The suction pipe 320 can suck out the sewage into the dredging device 300. Since the dirt at the well bottom can be blown up and mixed into the well water, when the suction pipe 320 sucks out the water in the recharge well 100, the dirt that can block the recharge device 200 can be fully sucked out. The dredging effect is good and the efficiency is high.

[0074] Specifically, as shown in Figure 3As shown, the dredging device 300 comprises a liquid storage tank 310, a suction pump 390 and an air pump 360. The liquid storage tank 310 comprises a tank body 317, which has an accommodating space. The end of the suction pipe 320 away from the recharge well 100 is in communication with the accommodating space, and the sewage can be pumped into the accommodating space. The suction pump 390 is arranged on the liquid storage tank 310 and is in communication with the suction pipe 320. The suction pump 390 is located on the path of the sewage entering the liquid storage tank 310 along the suction pipe 320, and the suction pump 390 can provide suction to the suction pipe 320 to suck out the sewage at the bottom of the well. The air pump 360 is arranged on the liquid storage tank 310, and the end of the air pipe 301 away from the recharge well 100 is in communication with the air pump 360. The air pump 360 can fill the air pipe 301 with gas, thereby inflating the recharge well 100. The structure is simple, the cost is low, and the operation is convenient.

[0075] In order to ensure the effect of dredging, as shown in Figure 3 The dredging device 300 further comprises a first pressure gauge 370, a second electromagnetic flowmeter 380 and a second pressure gauge 350. The second pressure gauge 350 is arranged on the air pipe 301 and located between the air pipe 301 and the air pump 360, and is used to detect the pressure of the gas in the air pipe 301. The first pressure gauge 370 is arranged on the suction pipe 320 and located between the suction pipe 320 and the suction pump 390, and is used to detect the pressure in the suction pipe 320. The pressure on the first pressure gauge 370 and the pressure value on the second pressure gauge 350 need to be consistent, so that the pressure in the recharge well 100 is balanced, and the danger caused by excessive pressure is avoided. The second electromagnetic flowmeter 380 is arranged on the suction pipe 320 and located between the suction pipe 320 and the suction pump 390, and can display the water volume of the pumped sewage, so as to control the pumping amount of the sewage, avoid the loss of underground water caused by excessive pumping amount of water, and avoid the influence of the dredging effect caused by too little pumping amount of sewage.

[0076] As an optional solution, in order to treat and recycle the sewage in the accommodating space, as shown in Figure 3 The accommodating space comprises a separation space 311 and a water storage space 312. The separation space 311 is arranged above the water storage space 312 and located on one side of the tank body 317. The liquid storage tank 310 comprises a filter screen 313. The bottom of the separation space 311 is in communication with the water storage space 312 through the filter screen 313, and the end of the suction pipe 320 is in communication with the separation space 311. After the sewage enters the separation space 311, it will flow downward due to the action of gravity. After being filtered by the filter screen 313, the solid impurities are left in the separation space 311, and the separated water enters the water storage space 312, thereby realizing solid-liquid separation. The structure is simple and the operation is convenient.

[0077] Further, as shown in Figure 3As shown, the liquid storage tank 310 further comprises a sewage valve 315 and a solid valve 314, which are arranged on the tank body 317, wherein the sewage valve 315 and the solid valve 314 are arranged on the side wall of the tank body 317, the sewage valve 315 is communicated with the water storage space 312, and the solid valve 314 is communicated with the separation space 311 and abuts against the filter screen 313, so as to facilitate the cleaning of solid substances. Opening the sewage valve 315 can discharge the filtered water without solid substances to a designated position, so as to facilitate the recycling of water and protect water resources. Opening the solid valve 314 can clean the solid substances left on the filter screen 313, so as to avoid clogging the filter screen 313.

[0078] As an optional solution, as shown in Figure 3 As shown, the liquid storage tank 310 further comprises a second roller 316, which is rotatably arranged below the tank body 317 and abuts against the workbench, so as to facilitate the movement of the liquid storage tank 310, thereby saving manpower, material resources and time cost.

[0079] As an optional solution, as shown in Figure 3 As shown, the dredging device 300 further comprises a pipe mouth disc 330 and a moving device 340, wherein the end of the inflation pipe 301 and the suction pipe 320 away from the recharge well 100 is fixedly arranged on the pipe mouth disc 330 and communicated with the corresponding inflation pump 360 or suction pump 390 through the pipe mouth disc 330. One end of the moving device 340 is connected with the pipe mouth disc 330, and the other end is rotatably connected with the liquid storage tank 310, and the rotation or movement of the moving device 340 relative to the liquid storage tank 310 can adjust the position of the pipe mouth disc 330, so as to facilitate the connection of the other end of the inflation pipe 301 and the suction pipe 320 with the pipe mouth disc 330 after the one end of the inflation pipe 301 and the suction pipe 320 penetrates through the well cover 130 and extends to the well bottom.

[0080] As an optional solution, as shown in Figure 3 and Figure 4 As shown, the well cover 130 is provided with an inflation through hole 131, a suction through hole 132 and a recharge hole 133, wherein the recharge pipe 260 penetrates into the recharge well 100 through the recharge hole 133, the inflation pipe 301 penetrates into the recharge well 100 through the inflation through hole 131, and the suction pipe 320 penetrates into the recharge well 100 through the suction through hole 132. As a preferred solution, the recharge hole 133 is arranged at the center of the well cover 130, the plurality of suction through holes 132 and the plurality of inflation through holes 131 are arranged adjacent to and spaced apart from each other around the recharge hole 133, each suction through hole 132 corresponds to one suction pipe 320, each inflation through hole 131 corresponds to one inflation pipe 301, and the plurality of suction pipes 320 and the plurality of inflation pipes 301 cooperate with each other, so as to make the dredging work more efficient.

[0081] Further, in order to simplify the structure and reduce the cost, the pipe orifice disc 330 is provided with suction channel and inflation channel (not shown in the figure), the upper end of the pipe orifice disc 330 is provided with suction power port and inflation power port (not shown in the figure), the lower end of the pipe orifice disc 330 is provided with multiple suction connection ports and multiple inflation connection ports, each suction connection port corresponds to a suction pipe 320, and each inflation connection port corresponds to an inflation pipe 301. The multiple suction connection ports are communicated with the suction power port through the suction channel, and the multiple inflation connection ports are communicated with the inflation power port through the inflation channel. The suction power port is communicated with the containing space through a suction power pipe, and the suction pump 390, the first pressure gauge 370 and the second electromagnetic flowmeter 380 are arranged on the suction power pipe. The inflation power port is communicated with the inflation pump 360 through an inflation power pipe, and the second pressure gauge 350 is arranged on the inflation power pipe. In this way, the dredging effect can be improved, and each suction pipe 320 corresponds to a suction pump 390, a first pressure gauge 370 and a second electromagnetic flowmeter 380, and each inflation pipe 301 corresponds to a second pressure gauge 350 and an inflation pump 360, so that the structure is simpler, the assembly is easier, and the cost is lower.

[0082] Specifically, as shown in Figure 3 The mobile device 340 includes a first mechanical arm 341, a second mechanical arm 344, a rotating shaft 343 and a connecting rod 342. The second mechanical arm 344 is rotatably arranged on the liquid storage tank 310, the first mechanical arm 341 and the second mechanical arm 344 are connected by the rotating shaft 343, one end of the connecting rod 342 is connected with the first mechanical arm 341, and the other end of the connecting rod 342 is connected with the second mechanical arm 344. The first mechanical arm 341 can rotate relative to the second mechanical arm 344 through the rotating shaft 343, and the connecting rod 342 is telescopic. The length of the connecting rod 342 can avoid that the angle of the first mechanical arm 341 relative to the second mechanical arm 344 is too large, so that the adjustment of the pipe orifice disc 330 is difficult. Specifically, the connecting rod 342 includes a first telescopic rod and a second telescopic rod (not shown in the figure), the first telescopic rod is connected with the first mechanical arm 341, the second telescopic rod is connected with the second mechanical arm 344, one of the first telescopic rod and the second telescopic rod is sleeved on the other and can slide relative to each other, and the end portions of the first telescopic rod and the second telescopic rod are provided with matched limiting convex blocks and limiting concave blocks respectively, so as to avoid that the first telescopic rod and the second telescopic rod are separated from each other when sliding relative to each other.

[0085] The operation method of the recharge and dredging system provided by the embodiment will be specifically described below.

[0086] Step S10, selecting a suitable well drilling position, and using a triaxial mixing pile to excavate and build the inner layer 120 and the outer layer 110 of the recharge well 100;

[0087] Step S20, the mobile recharge device 200 is moved to the recharge well 100, and the free end of the recharge pipe 260 is inserted into the inner layer 120 of the recharge well 100 through the recharge hole 133 of the well cover 130. The operator sends a start-up instruction through the remote processing platform, and the recharge processor 210 receives the detection data of the water level meter 224 and the third pressure gauge 221, and transmits them back to the remote processing platform. The operator can know the water amount and pressure in the pressure tank 220 through the data displayed on the remote processing platform. When the water amount is insufficient, the operator sends a water supplement instruction to the recharge processor 210 through the remote processing platform. If the water amount is sufficient but the pressure is too high, the operator sends a pressure relief instruction to the recharge processor 210 through the remote processing platform. The recharge processor 210 controls the exhaust valve 223 to open for exhaust after receiving the pressure relief instruction, until the third pressure gauge 221 detects that the pressure in the pressure tank 220 meets the requirements. The operator sets the recharge water amount through the remote processing platform and sends a valve opening instruction to the recharge processor 210. The recharge processor 210 controls the electric switch 250 to open for recharge into the recharge well 100 after receiving the valve opening instruction. If the water amount in the pressure tank 220 is sufficient but the pressure is too low, the operator sets the recharge water amount through the remote processing platform and sends a valve opening and pressure increasing instruction to the recharge processor 210. The recharge processor 210 controls the electric switch 250 to open and starts the pressure pump 230 for recharge into the recharge well 100 after receiving the valve opening and pressure increasing instruction. The recharge processor 210 can feed back the data measured by the first electromagnetic flowmeter 240, the third pressure gauge 221 and the water level meter 224 to the remote processing platform in real time during the recharge process, so that the operator can know the situation of the recharge process in real time. When the value measured by the first electromagnetic flowmeter 240 fed back to the remote processing platform by the recharge processor 210 is equal to the recharge water amount set by the operator in advance, the remote processing platform sends a valve closing instruction to the recharge processor 210. The recharge processor 210 controls the electric switch 250 to close after receiving the valve closing instruction, thereby completing the recharge process.

[0088] Step S30, when the first electromagnetic flowmeter 240, the third pressure gauge 221 and the water level gauge 224 displayed on the remote processing platform have differences with the data measured in the normal situation, the difference value shows that the recharge water flow is not smooth, then the operator needs to feedback the valve closing and shutdown instruction to the recharge processor 210, and the recharge processor 210 controls the electric switch 250 to close and shut down after receiving the instruction. The operator on site withdraws the recharge pipe 260 from the recharge well 100 and moves the recharge device 200 away from the recharge well 100, and at the same time moves the dredging device 300 to the side of the recharge well 100. In order to facilitate the movement of the dredging device 300 and the installation of the suction pipe 320 and the inflation pipe 301, first, one end of the suction pipe 320 is inserted into the bottom of the recharge well 100 through the suction through hole 132, and one end of the inflation pipe 301 is inserted into the bottom of the recharge well 100 through the inflation through hole 131. Then, by moving the device 340, the position of the pipe orifice plate 330 relative to the liquid storage tank 310 is moved, so that the pipe orifice plate 330 is moved to the top of the recharge well 100, and the other end of the suction pipe 320 and the inflation pipe 301 is connected with the corresponding hole below the pipe orifice plate 330.

[0089] Step 40, the operator sends the dredging device start-up instruction by using the remote processing platform, and the dredging controller controls the inflation pump 360 and the suction pump 390 to start at the same time after receiving the instruction. The bottom of the well is inflated through the inflation pipe 301 to make the solid substances float in the well water, so that the well water becomes sewage and is sucked out to the liquid storage tank 310 through the suction pipe 320. The dredging processor can transmit the values measured by the first pressure gauge 370, the second pressure gauge 350 and the second electromagnetic flowmeter 380 to the remote processing platform in real time, and the operator can monitor the suction process in real time according to the remote processing platform. When the water storage space 312 is full, the sewage valve 315 can be opened to discharge the filtered water in the water storage space 312 to the designated position, and when the filter screen 313 needs to be cleaned, the solid valve 314 can be opened to clean the filter screen 313.

[0090] Step S50, when the dredging work is completed, the operator sends the shutdown instruction to the dredging controller through the remote processing platform, and the dredging controller controls the inflation pump 360 and the suction pump 390 to stop after receiving the instruction. The operator on site dismounts the suction pipe 320 and the inflation pipe 301 from the pipe orifice plate 330. Move the dredging device 300 away from the recharge well 100, and repeat the steps of S20 to continue recharging the recharge well 100 until the recharging work is completed.
