Description

Technical Field

[0001] The present application belongs to the technical field of foundation pit dewatering, and specifically relates to a deep foundation pit dewatering device. Background Art

[0002] The excavation of foundation pits is a high-risk construction project. In water-rich geological conditions, due to the serious lack of soil bearing capacity and high water levels, foundation pit excavation is very likely to cause collapse and burial accidents if safe and effective support and precipitation measures are not taken. Therefore, in order to ensure engineering safety and environmental safety, it is particularly important to improve the precipitation efficiency and support level of foundation pits. Most of the existing foundation pit support devices do not have an adjustment structure, cannot be adjusted according to the width of the foundation pit, etc., and are not convenient to install, and cannot meet people's use needs well; and during precipitation, due to the serious lack of soil bearing capacity and high water levels, collapse and burial accidents are likely to occur.

[0003] For example, the application with publication number CN214832822U discloses a deep foundation pit dewatering device, including a dewatering mechanism arranged in the deep foundation pit, the dewatering mechanism including a water pump, a protective shell, a water pipe and a lifting assembly; a water collection well is opened on the bottom surface of the deep foundation pit, the protective shell is vertically slidably installed in the water collection well and is used to filter impurities, the water pump is installed in the protective shell, one end of the water pipe is installed on the water pump, the other end of the water pipe extends out of the deep foundation pit, and the lifting assembly is installed in the deep foundation pit and connected to the protective shell. This application has the effect of reducing the wear of the water pump.

[0004] However, the deep foundation pit dewatering device in the application cannot filter the silt in the water well, and is easy to block the water permeable holes, resulting in slow drainage after long-term use. Now a deep foundation pit dewatering device that can filter silt and large particles is provided. Utility Model Content

[0005] The purpose of the present application is to provide a deep foundation pit dewatering device in order to solve the above-mentioned problem that silt and large particles cannot be filtered and water holes are easily blocked.

[0006] The technical solution adopted in this application is as follows: a deep foundation pit dewatering device, a delivery pipe is fixedly installed on the surface of the drainage container, and the delivery pipe penetrates the surface of the water collection container and extends to the center of the inner wall of the water collection container, the delivery pipe is fixedly connected to the water collection container on the side away from the drainage container, a water collector cover is fixedly installed on the upper surface of the water collection container, a groove is provided at the center of the lower surface of the water collector cover, a base is fixedly connected to the lower surface of the water collection container, and a base groove is provided at the center of the surface of the base. A filter screen is movably inserted on the surface of the base groove.

[0007] By adopting the above technical solution, when the user uses the precipitation device to lower the groundwater level, a large amount of silt and large particles will be entrained while pumping water. During the drainage process, the user can plug the filter net into the base groove to filter the silt and large particles. After that, the groundwater enters the water permeable hole again, which is relatively clean and free of blockages. This ensures that the silt and large particles will not block the water permeable hole and the outlet pipe, ensuring that the precipitation efficiency of the precipitation device remains unchanged during long-term use.

[0008] In a preferred embodiment, water permeable holes are provided on the surface of the water collection container.

[0009] By adopting the above technical solution, a plurality of water permeable holes are opened on the surface of the water collecting container, and the water filtered by the handle can be discharged faster through the water permeable holes. The design structure of the plurality of water permeable holes improves the efficiency of precipitation.

[0010] In a preferred embodiment, a handle is welded to the edge of the upper surface of the drainage container.

[0011] By adopting the above technical solution, when using the precipitation device, the user can pick up the handle with his hand, which makes it more convenient for the user to pick up the device or adjust the placement of the device.

[0012] In a preferred embodiment, a water pump is fixedly connected to the center of the inner wall of the drainage container and a delivery pipe is movably connected to the surface of the water pump.

[0013] By adopting the above technical solution, after the filtered water enters the water collecting container, the water will be extracted by the water pump and transported to the outside of the deep foundation pit through the delivery pipe to achieve the purpose of precipitation.

[0014] In a preferred embodiment, a water outlet pipe is fixedly mounted on the upper surface of the water pump.

[0015] By adopting the above technical solution, after the groundwater enters the water collection container through the permeable holes, the water pump provides power and the groundwater is discharged from the deep foundation pit through the outlet pipe.

[0016] In a preferred embodiment, a pressure vessel tube is fixedly connected to the edge of the upper surface of the water pump, a faucet outlet pipe is welded to the upper side of the pressure vessel tube, and a faucet switch is movably installed on the upper surface of the pressure vessel tube.

[0017] By adopting the above technical solution, when there is a lot of groundwater in the deep foundation pit, it cannot be discharged from the outlet pipe. The user can turn on the faucet switch, and the groundwater will flow out quickly from the faucet outlet pipe, thereby improving the precipitation efficiency and preventing the groundwater from flowing back again due to slow drainage.

[0018] In a preferred embodiment, a water outlet groove is provided in an area on the upper portion of the surface of the drainage container corresponding to the water outlet pipe of the faucet.

[0019] By adopting the above technical solution, the length of the faucet outlet pipe is ensured to be able to comb the discharged water out of the deep foundation pit. At the same time, it plays a limiting role to prevent the faucet outlet pipe from slipping during long-term use.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0021] In the present application, when the user uses the precipitation device to lower the groundwater level, a large amount of silt and large particles will be entrained while pumping water. During the drainage process, the user can plug the filter net into the base groove to filter the silt and large particles. After that, the groundwater enters the water permeable hole again and is relatively clean without blockages. This ensures that the silt and large particles will not block the water permeable hole and the outlet pipe, ensuring that the precipitation efficiency of the precipitation device remains unchanged during long-term use, and the user does not need to clean it frequently, and the filter net is easy to replace.

[0029] A deep foundation pit dewatering device, a delivery pipe 2 is fixedly installed on the surface of a drainage container 1, and the delivery pipe 2 penetrates the surface of a water collecting container 4 and extends to the center of the inner wall of the water collecting container 4, the delivery pipe 2 is fixedly connected to the water collecting container 4 on the side away from the drainage container 1, a water collecting cover plate 3 is fixedly installed on the upper surface of the water collecting container 4, a groove is provided at the center of the lower surface of the water collecting cover plate 3, a base 7 is fixedly connected to the lower surface of the water collecting container 4, and a base groove 6 is provided at the center of the surface of the base 7. A filter net 9 is movably inserted on the surface of the base groove 6. When the user uses the dewatering device to lower the groundwater level, a large amount of silt and large particles will be entrained while pumping water. In the process of drainage, the user can insert the filter net 9 on the base groove 6 to filter the silt and large particles, and then the groundwater is relatively clean after entering the water permeable hole 5, without blockages, so that the silt and large particles will not block the water permeable hole 5 and the water outlet pipe 10, and the dewatering efficiency of the dewatering device will remain unchanged during long-term use.

[0030] The surface of the water collection container 4 is provided with water permeable holes 5. The surface of the water collection container 4 is provided with a plurality of water permeable holes 5, and the water filtered by the handle 11 can be discharged faster through the water permeable holes 5. The design structure of the plurality of water permeable holes 5 improves the efficiency of precipitation.

[0031] A handle 11 is welded on the edge of the upper surface of the drainage container 1. When the user uses the precipitation device, the user picks up the handle 11 by hand, which is more convenient for the user to take the device or adjust the placement of the device.

[0032] A water pump 15 is fixedly connected to the center of the inner wall of the drainage container 1, and a delivery pipe 2 is movably connected to the surface of the water pump 15. After the filtered water enters the water collection container 4, the water pump 15 will extract the water and transport it to the outside of the deep foundation pit through the delivery pipe 2 to achieve the purpose of precipitation.

[0033] The upper surface of the water pump 15 is fixedly provided with a water outlet pipe 10. After the groundwater enters the water collecting container 4 through the water permeable hole 5, the water pump 15 provides power, and the groundwater is discharged from the deep foundation pit through the water outlet pipe 10.

[0034] A pressure pipe 14 is fixedly connected to the edge of the upper surface of the water pump 15, a faucet outlet pipe 13 is welded to the upper side of the pressure pipe 14, and a faucet switch 12 is movably installed on the upper surface of the pressure pipe 14. When there is a lot of groundwater in the deep foundation pit, it cannot be discharged from the outlet pipe 10. The user can turn on the faucet switch 12, and the groundwater will flow out quickly from the faucet outlet pipe 13, thereby improving the precipitation efficiency and preventing the groundwater from flowing back again due to slow drainage.

[0035] A water outlet groove 8 is provided on the upper surface of the drainage container 1 in an area corresponding to the faucet outlet pipe 13. The length of the faucet outlet pipe 13 is ensured to comb out the discharged water outside the deep foundation pit, and at the same time, it plays a limiting role to prevent the faucet outlet pipe 13 from slipping during long-term use.

[0036] The implementation principle of the deep foundation pit dewatering device embodiment of the present application is:

[0037] When the user uses the precipitation device to lower the groundwater level, a large amount of silt and large particles will be entrained while pumping water. During the drainage process, the user can plug the filter net 9 into the base groove 6 to filter the silt and large particles. After that, the groundwater enters the water permeable hole 5 again, which is relatively clean and free of blockages. This ensures that the silt and large particles will not block the water permeable hole 5 and the outlet pipe 10, ensuring that the precipitation efficiency of the precipitation device remains unchanged during long-term use.
