Description

Technical Field

[0001] The invention relates to a drainage device, in particular to an intelligent underground space geological body water level dynamic stability regulation system. Background Art

[0002] Because underground space is located below the surface and is affected by the long-term action of groundwater, there is often a problem of water seepage in the underground space. Because the underground space is jointly carried by the geological body and groundwater, the groundwater cannot be pumped out only through the vertical shaft, otherwise it will cause a large change in the structure of the underground geological body. When water seepage in the underground space is found, the groundwater is directly pumped out by digging wells in the underground space. The defects of this method are: first, at this time the groundwater level has risen too much, a large amount of water will be pumped out, and the groundwater level will be lowered. During the pumping process, the structure of the geological body will change, which is easy to cause a large deformation of the geological body. Second, due to the high groundwater level, the sudden large-scale extraction of groundwater will lead to drastic changes in the geological environment.

[0003] Therefore, the geological structure of the underground space is affected by the frequent fluctuations of the groundwater level, so the geological structure of the underground space should be kept in a relatively stable geological environment, including the groundwater level is not prone to drastic changes. However, due to global climate change and other reasons, heavy rainfall and prolonged rainfall will cause water seepage or even accumulation in the underground space, which will not only change the geological environment but also induce deformation of the underground structure. Therefore, there is an urgent need for a device that can adjust the groundwater level in the geological body where the structure is located. Summary of the invention

DETAILED DESCRIPTION

[0046] The following is combined with Figure 1-13 The specific implementation modes of the present invention are further described in detail.

[0047] When the embodiment is in use, various monitoring points that need to be monitored are first selected in the underground space, and then a vertical shaft is drilled downward at the location of each monitoring point. The vertical shaft is a water well 1, so that the vertical shaft at least passes downward through the average groundwater level (preferably, groundwater always infiltrates into the water well 1), so that the groundwater can infiltrate into the water well 1, and then each water well 1 is placed for a period of time to allow the groundwater to naturally penetrate into the vertical shaft.

[0048] Embodiment 1, as Figure 1 As shown, a groundwater level detection device 2 is arranged in the groundwater well 1. In this embodiment, the groundwater level detection device 2 is a water level sensor, and the specific water level sensor can be an ultrasonic water level sensor or a pressure water level sensor. The water level sensor detects the water level in the well 1. The water level sensor is connected to the electric control box.

[0049] A pump 11 connected to the electric control box is installed in each water well 1. The pump 11 can pump water out of the water well 1. One end of the drainage pipe of the pump 11 is connected to the underground waterway. When the water well 1 needs to be filled with water, the municipal water supply pipe 12 can be connected through the water supply pipe 12. At this time, the municipal water supply pipe 12 is the water source for water supply. A control water valve 15 is installed on the water supply pipe 12, and the control water valve 15 is connected in the electric control box. The control water valve 15 can be an electric valve, a solenoid valve or a pneumatic valve. Or it can be connected to a water supply tank through a water supply pump, and the water supply tank is connected to the municipal water supply pipe. The pump 11 and the recharging pipe 12 constitute a pumping and filling device. The water supply tank can play a buffering role, and some additives can be added to the water supply tank. For example, some additives can change the pH value of the water body to flush the pipeline and prevent the pipeline from being blocked. When rapid recharge is required, the water supply tank is sealed and a pressure pump is connected to the outside of the water supply tank. The pressure pump increases the pressure in the water supply tank, so that the water in the water supply tank can be quickly recharged into the well, allowing the water in the well to quickly penetrate into the underground soil.

[0050] like Fig.13 As shown, the present invention also includes an intelligent alarm and detection module, which includes:

[0051] A temperature sensor 22, wherein a plurality of temperature sensors 22 are arranged vertically and spaced apart in the soil outside the well;

[0052] A soil displacement meter 23 is buried in the soil layer outside the well to measure the displacement of the soil;

[0053] A wireless signal transmitting device 25, which is connected to the electric control box 24 and is used to transmit wireless signals;

[0054] A wireless signal receiving device 26, wherein the wireless signal receiving device 26 cooperates with the wireless signal transmitting device 25;

[0055] A monitoring host 27, wherein the wireless signal receiving device 26 is connected to the monitoring host 27;

[0056] The temperature sensor 22 and the soil displacement meter 23 are both connected to the electric control box 24 .

[0057] The present invention transmits the information of groundwater and soil layers inside and outside the well to the wireless signal receiving device 26 of the monitoring center through a wireless signal transmitting device, and monitors it through a monitoring host 27 in the monitoring center. It can also include a handheld terminal 28. The monitoring center transmits the signal to the handheld terminal, such as a mobile phone, which can be used to view the information anytime and anywhere.

[0058] The intelligent alarm and detection module of the present invention is provided with a temperature sensor 22, which is vertically spaced in the soil outside the water well to detect the temperature of different layers of soil. At the same time, some of the multiple temperature sensors 22 are placed in the groundwater and some are placed above the groundwater layer. The change in temperature can also reflect the change in the groundwater level. A soil displacement meter 23 is provided, which can detect the displacement of the soil and is used to detect the displacement change of the underground soil layer in the underground space.

[0059] This wireless transceiver can not only transmit temperature and displacement to the detection host, but also transmit the water level information of the water level sensor, as well as the status of equipment installed in the electric control box such as the water pump and the control water valve to the detection host for real-time viewing by the monitoring center.

[0060] The monitoring center is equipped with an alarm function, which can be a pop-up window on the monitoring display or a text message reminder, so that when the water level rises and triggers the upper limit value or the water level drops and triggers the lower limit value, an alarm can be issued to remind the management personnel.

[0061] Because the groundwater level changes during the dry season or rainy season, or after the rainy season, the underground geology will change. The repeated changes in the underground geology will affect the geological stability.

[0062] The purpose of the present invention is to keep the groundwater level in the basement or underground space stable within a certain range, thereby stabilizing the humidity of the underground soil, ensuring the stability of the geological state, and ensuring its stability.

[0063] When the groundwater level rises due to rain, since well 1 is connected to the groundwater, the water level sensor can detect the rising water level in well 1. We set a water level interval, that is, the water level height interval in well 1. When the water level is within this water level interval, our pumping and irrigation device does not work. When the groundwater level rises and the water level in well 1 is higher than the upper limit of the water level interval, the water level sensor in well 1 detects that the water level has risen and is higher than the upper limit of the set water level interval, then the electric control box controls the pump 11 to pump water from well 1 until the water level in well 1 is lowered to the water level interval, and the pump 11 stops pumping. In the process of pumping, when the water level in well 1 drops, the groundwater continues to seep into well 1 to replenish the water in well 1. Therefore, when the water pump pumps the water in well 1 to the water level interval and the water in well 1 remains stable, pumping stops. Of course, the pump 11 can also stop pumping water at the middle value of the water level interval when the water level is reduced to the middle value. The purpose is to keep the groundwater level in a constant interval, maintain the stability of the groundwater level, and then maintain geological stability. We keep the groundwater level within the set water level interval to prevent geological instability or basement seepage caused by rising groundwater levels in the rainy season. The pumped water can be introduced into the reclaimed water system.

[0064] In the dry season, the groundwater level will drop. When the water level sensor detects that the water level in the well 1 drops to the lowest value of the water level interval, the recharging pipe 12 is started. Specifically, the water level sensor transmits the water level information to the electric control box, and sends a signal to the control valve 15 through the electric control box, so that the control valve 15 opens, and the recharging pipe 12 is connected to the municipal water supply pipe. At this time, the recharging pipe 12 supplies water to the well 1. After the water level in the well 1 rises, the water in the well 1 will seep into the groundwater to replenish the groundwater until the water level in the well 1 returns to the water level interval, and then the water supply to the well 1 is stopped. Of course, it is also possible to take another value within the water level interval to stop the water supply, such as the middle value of the water level interval, so that the water supply is stopped when the water level reaches the middle value of the water level interval. After the water supply is stopped, the water level can be allowed to change to a certain extent within the water level interval to avoid frequent pumping and irrigation. It ensures that the groundwater level under the underground space drops, causing the geological structure to change.

[0065] Example 2, in this example, we introduce a detection tube 3 into the water well 1, such as Figure 3As shown, the detection tube 3 is composed of a tube body and an annular sheet 20 at the upper end, and the annular sheet can conveniently place the detection tube 3 on the upper platform of the well 1. The lower end of the detection tube 3 is connected to the water seepage tube 4, and the water seepage tube 4 makes the space inside and outside the tube body communicate with each other through the hydrophobic channel 13 on the side. In order to prevent external soil particles or debris from entering the water seepage tube 4, the hydrophobic channel 13 on the water seepage tube 4 is an arched structure with bottoms at both ends and a high middle, so that water can be immersed while preventing soil particles and other debris from being immersed as much as possible. The hydrophobic channel 13 is a structure arranged in an array along the axial direction of the water seepage tube 4, which can make as many immersion channels as possible, prevent individual channels from being blocked and causing deviations in the results, and enable the inside and outside of the water seepage tube 4 to be connected in time.

[0066] like Figure 5 and Figure 6As shown, a tray 5 is connected to the lower end of the water seepage cylinder 4, and the tray 5 plays the role of supporting the hollow cylinder 7 (the tray 5 is a columnar structure with an upper opening, and the hollow cylinder 7 is fixed on the vertical side wall of the tray 5 through a plurality of connecting rods 19). One function of the hollow cylinder 7 is to support the groundwater level detection device 2 in this embodiment, so that the groundwater level detection device 2 remains vertically slidably connected to the hollow cylinder 7, and at the same time, the tray 5 at the lower end of the hollow cylinder 7 plays the role of collecting sediment. The tray 5 and the water seepage cylinder 4 can be connected by threads to form a structure in which the two can be disassembled. When there is too much sediment, the detection cylinder 3 can be pulled out, and then the tray 5 can be disassembled from the lower part of the water seepage cylinder 4, so that the debris deposited in the tray 5 can be cleaned. The conduit 9 on the tray 5 extends upward into the hollow cylinder 7, and the inner diameter of the hollow cylinder 7 is larger than the outer diameter of the conduit 9. At the same time, a water notch 8 is provided at the lower end of the hollow cylinder 7. The height of the conduit 9 extending upward is higher than the height of the water notch 8. We set the conduit 9 to always be in the liquid level in the well 1, so that the lower half of the hollow cylinder 7 including the water notch 8 is always in the water. The water from the outside will enter the hollow cylinder 7 through the water notch 8, and then the water in the hollow cylinder 7 will enter the conduit 9. In the process of water flowing from the well 1 into the conduit 9, it passes through a layer of filtration of the water notch 8, reducing the risk of impurities entering the conduit 9. One end of the conduit 9 is placed in the hollow cylinder 7, and the other end of the conduit 9 is connected to a three-way valve 10, which is an electrically controlled three-way valve, which is connected in the control box, and the other two ends of the three-way valve 10 are connected to the underground waterway and the recharging pipe 12 through the water pump 11. The municipal water supply pipe is connected through the recharging pipe 12, and the municipal water supply pipe is the source of the recharging water. A control water valve 15 is installed on the recharging pipe 12, and the control water valve 15 is connected to the electric control box. The control water valve 15 can be an electric valve, a solenoid valve or a pneumatic valve. When it is necessary to supply water to the water well 1, the electric control box controls the three-way valve 10 to connect the conduit 9 and the water supply pipe 12 (at this time, the conduit 9 and the water pump 11 are closed). When it is necessary to pump water from the water well 1, the electric control box controls the three-way valve 10 to connect the conduit 9 and the water pump 11 (at this time, the conduit 9 and the water supply pipe 12 are closed).

[0067] like Figure 7 , 8As shown in Figures 11 and 12, the water level detection device 2 in this embodiment is composed of the following devices: a sliding ring 201, a sliding block 202, a sliding rod 203, a slide 204, a floating member 205, a hollow ring 206, a touch switch 207 and a touch block 208. Multiple sliding blocks 202 are connected to a sliding ring 201, and the sliding ring 201 is vertically slidably sleeved on the hollow cylinder 7. A slide rod 203 is fixedly connected to the free end of the sliding block 202, and a vertical slideway 204 is opened on the slide rod 203. A floating member 205 is vertically slidably connected in the slideway 204. A hollow ring 206 is connected between the lower ends of multiple floating members 205. A touch switch 207 is fixedly connected to the upper, middle and lower positions of one of the slideways 204 respectively; a touch block 208 is arranged on the floating member in the slideway 204 where the touch switch 207 is arranged, and the touch block 208 is used to cooperate with the touch switch 207. The water level detection device 2 in this embodiment needs to be positioned during use. The sliding ring 201 of the water level detection device 2 can be positioned by means of the screw 14 (by opening a transparent threaded hole on the sliding ring 201 and then screwing in the screw 14. When positioning is required, the screw 14 is tightened so that the end of the screw 14 contacts the hollow cylinder 7 to form a positioning. When the position of the sliding ring 201 needs to be adjusted, the screw 14 is loosened and then the position of the sliding ring 201 is moved. After it is moved into place, the screw 14 is tightened to reposition it. Alternatively, the sliding ring 201 can be frictionally matched with the hollow cylinder 7 to perform damping positioning. Both methods are acceptable. After the sliding ring 201 is positioned. The floating member 205 connected to the vertical sliding sliding member 202 in this embodiment will float on the water surface. Since the lower end of the floating member 205 is a hollow ring 206, the hollow ring 206 will always be located on the water surface under the action of buoyancy, and the upper end of the floating member 205 is vertically slidably connected to the sliding rod 203. The upper end of the floating member 205 has a touch block 208, and a touch switch 207 (15) is fixedly connected to the upper, middle and lower positions of the slideway 204 (12) of one of the sliding rods 203 respectively; the touch block 208 cooperates with the touch switch 207 to trigger the touch switch 207. The touch switch 207 is connected in the electric control box.

[0068] When the groundwater level rises during the rainy season, the hollow ring 206 and the floating member 205 will be pushed up until the trigger block 208 on the floating member 205 contacts the trigger switch 207 at the top. At this time, the trigger switch at the top transmits the signal to the electric control box, and the electric control box controls the three-way valve 10 to connect the conduit 9 and the water pump 11, and then turns on the water pump 11 to pump out the water in the well 1 until the contact block touches the trigger switch 207 in the middle position, at which time the pumping work stops.

[0069] When the groundwater level drops in the dry season, the hollow ring 206 will drop along with the water level, and the trigger block 208 on the floating member 205 will also drop until the trigger block 208 triggers the trigger switch 207 at the bottom. The trigger switch 207 at the bottom sends a signal to the electrical control box, and the electrical control box controls the three-way valve 10 to connect the conduit 9 and the water supply pipe 12, and at the same time controls the control water valve 15 on the water supply pipe 12 to be connected, and the water from the municipal water pipe is connected to the well 1 to recharge the water. The water in the well 1 reversely infiltrates into the groundwater layer until the water level in the well 1 rises, driving the trigger block 208 to trigger the trigger switch 207 in the middle position, and the water supply is stopped.

[0070] By pumping water in the rainy season and replenishing it in the dry season, the groundwater layer is always within a controllable range regardless of whether the weather outside is dry or rainy, ensuring that the surrounding geological bodies are in a relatively stable state.

[0071] Embodiment 3, as Figure 2 and Figure 4 As shown, on the basis of Example 1 or Example 2. In order to increase the interactivity between groundwater and the water well 1, and to quickly infiltrate into the groundwater layer during recharge in the water well 1. A radial infiltration pipe 16 is arranged on the part of the water well 1 located in the groundwater, and liquid is exchanged between the infiltration pipe 16 and the external groundwater, and the infiltration pipe 16 is connected to the water well 1. The structure of the infiltration pipe 16 is: it includes a hollow pipe, a plurality of water-permeable holes are opened on the outer wall of the hollow pipe, a geotextile 17 is wrapped on the outside of the hollow pipe, and a gauze 18 is wrapped on the outside of the geotextile 17. The infiltration pipe 16 can be closed at the ends.

[0072] Groundwater can penetrate into the seepage collecting pipe 16 through the gauze 18 and the geotextile 17, and the seepage collecting pipe 16 is connected to the well 1 and can interact with the water in the well 1. When water is injected into the well 1, the water in the well 1 can quickly penetrate into the underground soil layer through the seepage part at the lower end of the well 1, the seepage collecting pipe 16, the permeable geotextile 17 and the gauze 18.

[0073] The gauze 18 not only plays a filtering role, but also plays a role in protecting the permeable geotextile 17.

[0074] In this embodiment, the seepage collecting pipe 16 is provided to accelerate the interaction between the water well 1 and the groundwater, so that the rise and fall of the groundwater can be more quickly reflected in the water well 1, and the pumping or replenishing of water in the water well 1 can be quickly reflected in the groundwater layer.

[0075] Example 4, based on any one of Examples 1-3, in order to increase the safety of the water well 1, a protective device is set at the upper end of the water well 1, and the protective device can be a well house or a well cover 21. In order to improve the filtering effect of the seepage pipe, a layer of geotextile 17 is wrapped on the outer layer of the seepage pipe, and a gauze 18 is wrapped on the outside of the geotextile 17. A permeable layer is set at the lower part of the water well 1, which is a prior art and will not be repeated here.
