Description

Technical Field

[0001] This application relates to the field of foundation pit maintenance, and more specifically, to a drainage structure for foundation pits. Background Technology

[0002] When it rains, the foundation pit will fill with water. If the foundation pit is soaked in water for a long time, the inner wall of the foundation pit may collapse, resulting in the foundation pit sinking. Therefore, it is necessary to drain the water out of the foundation pit in a timely manner.

[0003] Generally, pumps and pipes are used to directly drain water from the foundation pit. However, when the pipes are placed in the foundation pit, they sink directly to the bottom. Only when the pipes are at the bottom of the foundation pit can most of the water be drained out. But if the pipes are at the bottom of the foundation pit, the pipes will also drain the soil from the foundation pit. Therefore, it is common to install various filters on the pipes. However, the filters will become clogged after a long time and need to be replaced frequently, resulting in complicated drainage and poor drainage stability. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] To address the technical problems mentioned in the background section, some embodiments of this application provide a drainage structure for a foundation pit, comprising: a mobile carrier, a pump body, a drain pipe, a water supply pipe, and a water collection tank; the pump body is mounted on the mobile carrier, one end of the drain pipe is connected to the pump body, and the other end extends into the foundation pit; one end of the water supply pipe is connected to the pump body, and the other end extends into the water collection tank; wherein, a floating member is provided at the end of the drain pipe, and the floating member has a cavity so that when the drain pipe is inserted into the foundation pit, the floating member floats on the water surface of the foundation pit.

[0006] Furthermore, the end of the drain pipe is provided with a filter element having multiple filter holes.

[0007] Furthermore, the filter element has a curved filter surface that covers the end of the drain pipe.

[0008] Furthermore, the filter surface protrudes outward; the filter element is made of elastic material; when the filter hole is blocked, the pressure in the drain pipe decreases, causing the filter element to deform inward toward the drain pipe until the filter surface protrudes inward; when the filter hole is unobstructed, the pressure in the drain pipe increases, causing the filter element to return to its original position outside the drain pipe until the filter surface protrudes outward.

[0009] Furthermore, an annular plate is provided on the filter element, and the annular plate is fixed to the filter element; the annular plate is threadedly connected to the end of the drain pipe.

[0010] Furthermore, the float includes a connecting ring and a float ball, the float ball being connected to the connecting ring, and the connecting ring being fixed to the drain pipe.

[0011] Furthermore, the float also includes a connecting rope, one end of which is fixed to the float ball, and the other end of which is fixed to the connecting ring.

[0012] The beneficial effects of this application are as follows:

[0013] By using the floating components, the drainage pipe is positioned near the water surface of the foundation pit, allowing it to move more smoothly with changes in water level. This reduces the amount of soil that needs to be discharged from the foundation pit, thus better protecting it. Attached Figure Description

[0029] A drainage structure for a foundation pit includes: a mobile carrier 1, a pump body 2, a drain pipe 3, a water supply pipe 4, and a collection tank 5. The pump body 2 is mounted on the mobile carrier 1. One end of the drain pipe 3 is connected to the pump body 2, and the other end extends into the foundation pit. One end of the water supply pipe 4 is connected to the pump body 2, and the other end extends into the collection tank 5. A floating component is provided at the end of the drain pipe 3. The floating component has a cavity so that when the drain pipe 3 is inserted into the foundation pit, the floating component floats on the water surface. The floating component is designed to ensure that the end of the drain pipe 3 floats better on the water surface or in a shallow underwater position, preventing the drain pipe 3 from falling directly to the bottom of the foundation pit due to its own weight. Furthermore, the presence of water in the foundation pit makes the bottom soft, preventing the drain pipe 3 from being buried in the pit due to its own weight, thus avoiding blockage at the end of the drain pipe 3. This ensures better and more continuous stability of the foundation pit drainage. In addition, the drainage pipe 3 is located near the water surface of the foundation pit. There is less silt in this location, which helps to better retain the silt in the foundation pit and prevent the soil of the foundation pit itself from being discharged outward. This allows for better maintenance of the foundation pit while draining it.

[0030] Specifically, the end of the drain pipe 3 is equipped with a filter element 6 with multiple filter holes. The filter element 6 is used to filter the silt and sand, preventing the silt and sand from being discharged, and better draining the foundation pit while maintaining it. Since the drain pipe 3 is located near the water surface, the amount of silt and sand at the filtration location of the filter element 6 is also reduced, and the filter element 6 is less likely to be clogged.

[0031] Specifically, the filter element 6 has a curved filter surface 61 that covers the end of the drain pipe 3. The curved design of the filter surface 61 can better increase the area of ​​the filter surface 61 and improve the stability of filtration.

[0032] Specifically, the filter surface 61 protrudes outward; the filter element 6 is made of elastic material; when the filter holes are blocked, the pressure in the drain pipe 3 decreases, causing the filter element 6 to deform inward toward the drain pipe 3 until the filter surface 61 protrudes inward; when the filter holes are unobstructed, the pressure in the drain pipe 3 increases, causing the filter element 6 to return to its original position outside the drain pipe 3 until the filter surface 61 protrudes outward. The filter element 6 is made of elastic material, preferably an elastic rubber sheet. Because the filter element 6 is elastic, when the filter holes on the filter element 6 are blocked, the filter element 6 deforms inward toward the drain pipe 3, and then the filter holes are squeezed and enlarged. When the filter holes are squeezed, the sediment in the filter holes is also squeezed, and the sediment in the filter holes also decreases as the filter holes decrease, and then the filter holes enlarge again, making the sediment smaller than the filter holes. Therefore, the sediment can pass through the filter holes, and thus the originally blocked filter holes become unblocked. Then the filter element 6 will reset under its own elasticity, so that the filter element 6 can remain unobstructed for a long time and better filter most of the mud and sand.

[0033] Specifically, an annular plate 7 is provided on the filter element 6, and the annular plate 7 is fixed to the filter element 6; the annular plate 7 is threadedly connected to the end of the drain pipe 3. This facilitates the disassembly and replacement of the filter element 6 when it experiences elastic fatigue.

[0034] Specifically, the float assembly includes a connecting ring 8 and a float 81. The float 81 is connected to the connecting ring 8, and the connecting ring 8 is fixed to the drain pipe 3. The float assembly also includes a connecting rope 82. One end of the connecting rope 82 is fixed to the float 81, and the other end of the connecting rope 82 is fixed to the connecting ring 8. By using the float 81 and the connecting rope 82, the end of the drain pipe 3 can be completely submerged below the water surface, better ensuring that the drain pipe 3 discharges water from the pit.

Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
