Description

Technical Field

[0001] The utility model belongs to the technical field of precipitation well cleaning, in particular to a well cleaning device for cleaning sediment in a precipitation well. Background Art

[0002] A dewatering well is an engineering facility used to lower the groundwater level. It's primarily used to control groundwater levels within construction sites, preventing groundwater infiltration into foundation pits or tunnels during construction, potentially impacting project safety. Dewatering wells are primarily used in deep foundation pit excavation, tunnel construction, and subway station construction.

[0003] Sediment is easily generated in precipitation wells during the pumping process. If not handled properly, it will lead to equipment blockage, increased pump wear, and even cause the well wall to collapse. At present, there are some sediment cleaning equipment for precipitation wells on the market. For example, a well washing system for cleaning sediment in precipitation wells is disclosed on the China Patent Network. Its announcement number is CN216948706U. This well washing system can be used for cleaning sediment in precipitation wells, but there are some defects and deficiencies that need to be improved: (1) Some existing well washing equipment will use high-pressure water flow to wash the well wall and bottom of the precipitation well in order to flush out the attached sediment. However, due to structural design reasons, the flushing range of the high-pressure water flow is small and can often only be concentrated on one point, and it is difficult to fully cover the entire well wall of the precipitation well, and there is a blind spot for cleaning. , which causes some mud and sand impurities to remain on the surface of the well wall and cannot be cleaned thoroughly; (2) Some existing well-washing equipment lacks effective filtering measures. When flushing the mud and sand in the precipitation well, the mud and sand easily enter and accumulate inside the flushing equipment, causing pipe blockage, which in turn leads to interruption of the cleaning work; (3) After completing the cleaning of the precipitation well, some existing well-washing equipment needs to use a mud pump to suck out the mixture of mud and water and discharge it to a designated location. However, in this process, the mud and sand can often only be sucked out from one pipe, which makes the extraction speed of the mud pump slow, thereby affecting the efficiency of the overall cleaning work. Therefore, in response to the above problems, the well-washing device for cleaning mud and sand in precipitation wells provided by the utility model is of great significance. Utility Model Content

[0004] The utility model provides a well washing device for cleaning sediment in precipitation wells. The high-pressure flushing mechanism can use high-pressure water flow to flush the well wall and the well bottom of the well pipe, thereby preventing sediment from remaining and adhering to the well wall and the well bottom. The flushing range of the high-pressure flushing mechanism can be effectively expanded through multiple flushing ports, so that the high-pressure water flow can fully cover the well wall of the entire well pipe, thereby effectively avoiding the existence of a cleaning blind area, which causes some sediment impurities to remain on the well wall surface and cannot be cleaned thoroughly; the filter plugs in each flushing port can block and filter the sediment impurities in the well pipe, thereby effectively preventing sediment from remaining and adhering to the well wall and the well bottom. Prevent mud and sand impurities from entering and accumulating in the flushing port to cause blockage and interrupt the cleaning work; the mixture of mud and water can be extracted and introduced into the recovery tank through the mud extraction mechanism, so that the extracted mud can be recovered through the recovery tank for subsequent unified treatment. The mud extraction range of the mud extraction mechanism can be effectively expanded through multiple mud extraction ports, so that the mixture of mud and water in the precipitation well can be simultaneously sucked into the mud extraction bin through the mud extraction ports at various angles, thereby greatly accelerating the speed of mud extraction, and then improving the efficiency of the overall cleaning work. In summary, the problems in the background technology are solved.

[0029] See also Figure 1-4As shown, the utility model is a well washing device for cleaning sediment in a precipitation well, comprising a well pipe 1, the well pipe 1 being laid on the ground, and the well pipe 1 being provided with a high-pressure washing mechanism and a sediment extraction mechanism;

[0030] The high-pressure flushing mechanism includes a first base 2, which is placed on the ground and on which a high-pressure water pump 3 is installed. A water inlet pipe 4 is installed on the high-pressure water pump 3. The end of the water inlet pipe 4 is fixedly connected to a flushing chamber 5. The flushing chamber 5 is annular, with a hollow structure inside and connected to the water inlet pipe 4. A plurality of flushing ports 6 are opened on the side wall of the flushing chamber 5. The high-pressure water pump 3 is connected to an external water source. By driving the high-pressure water pump 3, water can be introduced into the flushing chamber 5 along the water inlet pipe 4 and sprayed out through each flushing port 6, so that the well wall and bottom of the well pipe 1 are flushed with high-pressure water flow, thereby preventing sediment from remaining and adhering to the well wall and bottom.

[0031] The sediment extraction mechanism includes a second base 7, which is placed on the ground, and a sediment pump 8 and a recovery tank 9 are respectively installed on the second base 7, and a mud pumping pipe 10 and a mud discharge pipe 11 are respectively installed on the sediment pump 8. The other end of the mud discharge pipe 11 is fixedly connected to the side wall of the recovery tank 9 and is connected to the recovery tank 9. The end of the mud pumping pipe 10 is fixedly connected to a mud pumping bin 12. The cross section of the mud pumping bin 12 is circular, and its interior is a hollow structure and is connected to the mud pumping pipe 10. A number of mud pumping ports 13 are provided on the side wall of the mud pumping bin 12. When the sediment in the precipitation well is mixed with water under the action of high-pressure water flow, the mixture of sediment and water can be sucked into the mud pumping bin 12 from each mud pumping port 13 by driving the sediment pump 8, and introduced into the recovery tank 9 by the mud pumping pipe 10 and the mud discharge pipe 11, so that the extracted sediment can be recovered through the recovery tank 9 for subsequent unified treatment.

[0032] Among them, the bottom of the first base 2 and the second base 7 are fixedly connected with several positioning rods 14, and the bottom ends of the positioning rods 14 are spike-shaped. When the first base 2 and the second base 7 are placed on the ground, each positioning rod 14 can be inserted into the ground soil to play a positioning role, thereby effectively improving the stability of the high-pressure flushing mechanism and the sediment extraction mechanism to prevent them from displacement during operation.

[0033] Among them, the flushing port 6 is connected to the inner cavity of the flushing chamber 5, and the flushing ports 6 are equidistantly distributed in an annular shape along the circumferential direction of the flushing chamber 5. The flushing range of the high-pressure flushing mechanism can be effectively expanded through multiple flushing ports 6, so that the high-pressure water flow can fully cover the entire well wall of the well pipe 1, thereby effectively avoiding the existence of a cleaning blind spot, which causes some mud and sand impurities to remain on the well wall surface and cannot be cleaned.

[0034] Among them, a filter plug 15 is installed in each flushing port 6, the outer diameter of the filter plug 15 is equal to the inner diameter of the flushing port 6, and a filter mesh 16 is installed on the filter plug 15. The filter plug 15 can be inserted and fit on the inner wall of the flushing port 6 so as to fix the filter plug 15 in each flushing port 6. When high-pressure flushing is performed, the filter mesh 16 on the filter plug 15 can be used to block and filter the mud and sand impurities in the well pipe 1, so as to effectively prevent the mud and sand impurities from entering and accumulating in the flushing port 6 to cause blockage and interruption of the cleaning work.

[0035] Among them, the top of the first base 2 is fixedly connected to a support rod 17, and the top of the support rod 17 is fixedly connected to a limiting tube 18. The limiting tube 18 is sleeved on the tube body of the water inlet pipe 4, and its inner diameter is equal to the outer diameter of the water inlet pipe 4. The water inlet pipe 4 can be limited and fixed by the limiting tube 18 to improve the stability of the water inlet pipe 4, thereby preventing it from shaking during high-pressure flushing.

[0036] Among them, the mud pumping port 13 is connected to the inner cavity of the mud pumping bin 12, and its end is trumpet-shaped, and the mud pumping port 13 is equidistantly distributed in a ring shape along the circumferential direction of the mud pumping bin 12. Through multiple mud pumping ports 13, the mud pumping range of the mud and sand extraction mechanism can be effectively expanded, so that the mixture of mud and water in the precipitation well can be simultaneously sucked into the mud pumping bin 12 through the mud pumping ports 13 at various angles, thereby greatly accelerating the speed of mud and sand extraction, and then improving the efficiency of the overall cleaning work.

[0037] Among them, a number of connecting rods 19 are fixedly connected to the inner side of the flushing bin 5, and the ends of the connecting rods 19 are fixedly connected to the limiting rings 20. The limiting rings 20 are sleeved on the tube body of the mud pumping pipe 10, and the inner diameter thereof is equal to the outer diameter of the mud pumping pipe 10. The mud pumping pipe 10 can be limited and fixed by the limiting rings 20, so that the mud pumping pipe 10 and the mud pumping bin 12 can be located directly below the flushing bin 5. At the same time, it can also improve the stability of the mud pumping pipe 10 and prevent it from shaking during the process of mud and sand extraction.

Needless to say, the content protected by the present invention does not involve improvements to software and methods.

[0041] When the present invention is in use, the high-pressure water pump 3 can be connected to an external water source, and then the high-pressure water pump 3 can be driven to introduce water into the flushing bin 5 along the water inlet pipe 4, and sprayed out through each flushing port 6, so as to utilize the high-pressure water flow to flush the well wall and the bottom of the well pipe 1, thereby preventing the sediment from remaining and adhering to the well wall and the bottom of the well. When the sediment in the precipitation well is mixed with water under the action of the high-pressure water flow, the sediment and water mixture can be sucked into the sediment extraction bin 12 through each sediment extraction port 13 by driving the sediment pump 8, and is introduced into the recovery tank 9 through the sediment extraction pipe 10 and the sediment discharge pipe 11, so that the extracted sediment can be recovered through the recovery tank 9 for subsequent unified treatment.
