Description

Technical Field

[0001] This application relates to dewatering equipment for foundation pits, and more particularly to a seepage-proof dewatering pipe well. Background Technology

[0002] Wellpoint dewatering involves installing wells in areas with high groundwater levels (such as foundation pits) and setting up wellpoints within these wells. These wellpoints are connected to the groundwater, creating a hydraulic connection. Pumping equipment is then installed at the wellpoints to extract the groundwater, thereby lowering the water level at those wellpoints. This lowering of the water level at the wellpoints allows for the extraction and management of groundwater.

[0003] A current patent (publication number: CN222295041U) discloses a dewatering device for fine sand foundation pits, including a dewatering manhole and a pump. A steel plate is installed at the upper end of the dewatering manhole, and drainage holes are opened on the outer surface of the manhole. A drainage pipe is fixedly connected to the upper end of the pump, penetrating the steel plate. A filter structure is provided on the outer surface of the pump, comprising a filter frame, an annular cleaning brush, a column, a rectangular groove, a servo motor, bearings, a threaded rod, a first groove, a rectangular slide, a rectangular slider, a lifting column, and a lifting sleeve. This utility model's dewatering device for fine sand foundation pits can filter the fine sand in the foundation pit during pumping, preventing it from entering the pump and causing damage. It can also automatically clean the outer surface of the filter frame, preventing blockage and low pumping efficiency.

[0004] While the device described in the aforementioned comparative document solves the problem of its inability to filter fine sand, which could lead to the pump sucking in fine sand and causing damage, this device, by placing the filtration and cleaning structure inside the lifting sleeve, can only clean the inside of the lifting sleeve. Filtration, however, filters fine sand to the outside of the lifting sleeve. Therefore, the cleaning structure in this device is not very effective. Furthermore, the filtration structure is simplistic and has poor filtration efficiency. To address these issues, a seepage-proof dewatering well is proposed. Utility Model Content The purpose of this application is to provide a seepage-proof dewatering well with advantages such as filtration function and cleaning structure, which solves the problems of poor cleaning effect and poor filtration effect.

[0005] The seepage-proof dewatering pipe well provided in this application adopts the following technical solution: it includes a soil layer, a pipe body, a top cover and a cylinder. A borehole is opened inside the soil layer, the pipe body is located inside the borehole, a filter material is provided between the pipe body and the borehole, and a grouting-reinforced soil seepage-proof body is provided on the inner side of the borehole. The cylindrical body is located inside the tube. Four lower connecting rods are fixedly connected to the bottom of the cylindrical body, and four middle connecting rods are fixedly connected to the top of the cylindrical body. A connecting plate is fixedly connected to the top of each middle connecting rod. Two upper connecting rods and two empty cylinders are fixedly connected to the top of the connecting plate.

The moving ring and the ring scraper are coaxial with the cylindrical body. A connecting spring is fitted on the surface of the cylindrical body. The top and bottom ends of the connecting spring are fixedly connected to the bottom of the connecting plate and the top of the moving ring, respectively. Multiple filter holes are opened on the surface of the cylindrical body. By adopting the above technical solution, the filter holes can effectively filter impurities in the water, ensuring smooth water flow while preventing blockage. By setting up a pull rope, when it is necessary to filter impurities on the outer wall of the cylinder, people can pull the pull rope, and with the help of the connecting spring, the moving ring and the annular scraper can move up and down inside the cylinder, thereby cleaning the dirt attached to the outer wall of the cylinder. This can maintain the efficient operation of the equipment. The pull rope design makes it easy for operators to control the movement of the annular scraper from the outside, simplifying the maintenance process and improving the practicality and durability of the seepage-proof dewatering well.

[0006] Preferably, a plurality of lower filter plates are fixedly connected to the surface of the lower connecting rod, and a plurality of upper filter plates are fixedly connected to the surface of the upper connecting rod and the empty cylinder; By adopting the above technical solution and setting up upper and lower filter plates, the filtration effect on impurities in the water can be further enhanced, the overall filtration efficiency can be improved, and the multi-layer filter structure design can effectively disperse water flow pressure and avoid equipment failure caused by local blockage. At the same time, the spacing between the upper and lower filter plates can make the water flow distribution more uniform, thereby extending the service life of the equipment and reducing the maintenance frequency.

[0007] Preferably, the top cover is located at the top of the tube body; By adopting the above technical solution, the top cover can effectively seal the top of the pipe body, preventing external impurities from entering the pipe body, thereby further ensuring the normal operation of the equipment. At the same time, the detachable feature of the top cover provides convenience for the daily maintenance and repair of the equipment.

[0008] Preferably, the top of the top cover has a through hole, and the top of the top cover is provided with multiple winding rods; By adopting the above technical solution and setting multiple winding rods, effective external fixing points can be provided.

[0009] Preferably, a fixing ring is fixedly connected to the top end of the upper connecting rod, and a hanging rope is provided at the top end of the fixing ring; By adopting the above technical solution and setting up a fixing ring and a tethering rope, the stability and safety of the equipment during use can be effectively enhanced. The stable connection design of the fixing ring can ensure that the tethering rope will not loosen when it bears a certain tension, thereby avoiding equipment displacement or tipping due to external factors.

[0010] Preferably, the top of the traction rope and the pull rope are both located on the top of the top cover and are wrapped around the surface of the winding rod; By adopting the above technical solution, and by designing the tow rope and pull rope to be wound around the surface of the winding pole, the safety and reliability of the equipment can be enhanced, while also improving the maintenance efficiency and usage flexibility of the equipment.

[0016] The following is in conjunction with the appendix Figure 1 —Appendix Figure 6 This application will be described in further detail below.

[0017] Example 1: A seepage-proof dewatering well, referring to Figure 1 , Figure 5 and Figure 6 It includes a soil layer 1, a pipe body 2, a top cover 3 and a cylinder 4. A borehole 101 is opened inside the soil layer 1. The pipe body 2 is located inside the borehole 101. A filter material 103 is provided between the pipe body 2 and the borehole 101. A grouting reinforced soil seepage barrier 102 is provided on the inner side of the borehole 101. The cylinder 4 is located inside the tube 2. Four lower connecting rods 401 are fixedly connected to the bottom of the cylinder 4, and four middle connecting rods 402 are fixedly connected to the top of the cylinder 4. A connecting plate 403 is fixedly connected to the top of the middle connecting rods 402. Two upper connecting rods 404 and two empty cylinders 405 are fixedly connected to the top of the connecting plate 403. A pull rope 4011 is threaded through the inside of the empty cylinder 405. The bottom end of the pull rope 4011 slides through the connecting rod and is fixedly connected to a moving ring 4012. Multiple uprights 4013 are fixedly connected to the bottom of the moving ring 4012. A ring scraper 4014 is fixedly connected to the bottom of the uprights 4013. The moving ring 4012 and the ring scraper 4014 are coaxial with the cylinder 4. A connecting spring 4017 is sleeved on the surface of the cylinder 4. The top and bottom ends of the connecting spring 4017 are fixedly connected. Connected to the bottom of the connecting plate 403 and the top of the moving ring 4012, the surface of the cylinder 4 is provided with multiple filter holes 4015. By setting the filter holes 4015, impurities in the water can be effectively filtered, ensuring smooth water flow while preventing blockage. By setting the pull rope 4011, when it is necessary to filter impurities on the outer wall of the cylinder 4, people pull the pull rope 4011, and then with the setting of the connecting spring 4017, the moving ring 4012 and the annular scraper 4014 can move up and down inside the cylinder 4, thereby cleaning the dirt attached to the outer wall of the cylinder 4, thus maintaining the efficient operation of the equipment. The design of the pull rope 4011 makes it easy for operators to control the movement of the annular scraper 4014 from the outside, simplifying the maintenance process and improving the practicality and durability of the seepage-proof dewatering well.

[0018] Please see Figure 3 and Figure 4 Multiple lower filter plates 407 are fixedly connected to the surface of the lower connecting rod 401, and multiple upper filter plates 406 are fixedly connected to the surface of the upper connecting rod 404 and the empty cylinder 405. By setting up upper filter plates 406 and lower filter plates 407, the filtration effect on impurities in the water can be further enhanced, and the overall filtration efficiency can be improved. The multi-layer filtration structure design can effectively disperse water flow pressure and avoid equipment failure caused by local blockage. At the same time, the spacing between the upper filter plates 406 and the lower filter plates 407 can make the water flow distribution more uniform, thereby extending the service life of the equipment and reducing the maintenance frequency.

[0019] Please see Figure 4 and Figure 5The top cover 3 is located at the top of the pipe body 2. By setting the top cover 3, the top of the pipe body 2 can be effectively sealed to prevent external impurities from entering the pipe body 2, thereby further ensuring the normal operation of the equipment. At the same time, the detachable feature of the top cover 3 provides convenience for daily maintenance and repair of the equipment. Operators can quickly open the top cover 3 for internal cleaning or component replacement, which greatly improves the efficiency and flexibility of the equipment. The top of the top cover 3 has a through hole 301 and multiple winding rods 302. By setting multiple winding rods 302, effective external fixing points can be provided. The top of the upper connecting rod 404 is fixedly connected to a fixing ring 409, and the top of the fixing ring 409 is provided with a hook. Rope 4010, with its fixed ring 409 and traction rope 4010, effectively enhances the stability and safety of the equipment during use. The stable connection design of the fixed ring 409 ensures that the traction rope 4010 will not loosen when bearing a certain tensile force, thereby preventing equipment displacement or tipping due to external factors. The top of the traction rope 4010 and the pull rope 4011 are both located on the top of the top cover 3 and are wrapped around the surface of the winding rod 302. By wrapping the traction rope 4010 and the pull rope 4011 around the surface of the winding rod 302, the safety and reliability of the equipment are enhanced, while also improving the maintenance efficiency and operational flexibility of the equipment.

[0020] Please see Figure 4 and Figure 6 The lower connecting rod 401, the upper connecting rod 404, and the surface of the empty cylinder 405 are all movably connected to a U-shaped rotating plate 501 via pins. Inside the U-shaped rotating plate 501, a roller 502 is movably connected via pins. By setting the U-shaped rotating plate 501 and the roller 502, the operating efficiency and adaptability of the equipment can be further improved. The U-shaped rotating plate 501, with its movable pin connection, can flexibly adjust its angle to better adapt to different usage scenarios. The addition of the roller 502 effectively reduces friction and improves the smoothness of the equipment during the well-down process. A pump body 4016 is fixedly connected to the top of the cylinder 4. A water outlet pipe 408 is set at the output end of the pump body 4016. The output end of the water outlet pipe 408 is located at the top of the top cover 3. By setting the pump body 4016, the liquid inside the cylinder 4 can be extracted and discharged through the water outlet pipe 408, thereby achieving effective management of the liquid inside the well.

[0021] The implementation principle of this application embodiment is as follows: In actual operation, the pipe body 2 is first placed into the soil layer 1 through the drill hole 101, and the gap between the pipe body 2 and the drill hole 101 is filled with filter material 103 to enhance the seepage prevention effect. At the same time, the setting of the grouting reinforced soil seepage prevention body 102 further improves the stability and sealing of the overall structure, which can prevent external water sources from seeping in and affecting the operation of external equipment. When the pump body 4016 is running, the liquid inside the cylinder 4 can be drawn out through the water outlet pipe 408, thereby achieving effective management of the liquid inside the well. During this process, the water flows through multiple layers of filtration by the upper filter plate 406 and the lower filter plate 407, ensuring the cleanliness of the water quality, while effectively dispersing the water flow pressure and avoiding the occurrence of local blockage problems. To maintain the efficient operation of the pump body 4016, operators can control the up-and-down movement of the annular scraper 4014 by pulling the pull rope 4011, thereby cleaning the dirt adhering to the outer wall of the cylinder 4. This design not only simplifies the maintenance process but also significantly improves the durability of the equipment. In addition, the combined use of the U-shaped rotating plate 501 and the roller 502 makes the equipment smoother during the well lowering process, reduces the impact of friction, and also enhances the equipment's adaptability to different usage scenarios. The detachable design of the top cover 3 provides convenience for daily maintenance, while the stable connection between the fixing ring 409 and the traction rope 4010 further ensures the safety and reliability of the equipment, enabling it to withstand a certain amount of external tension without loosening or displacement.
