Description

Technical Field

[0001] This utility model relates to the field of foundation drainage technology, specifically to a drainage structure for soft soil foundations. Background Technology

[0002] In the continuous development of urbanization and construction, the cleaning and maintenance of pipeline systems have become crucial tasks to ensure the long-term stable operation of infrastructure, especially in soft soil foundation areas. The accumulation of silt in pipelines often leads to drainage problems, affecting the normal operation of the pipeline system. Among them, announcement number CN221501950U discloses a drainage structure for soft soil foundations, including a vertical pipe. A vertical pipe cover is fixedly installed on the top of the vertical pipe. A drainage groove is opened on the upper surface of the vertical pipe cover. A first bushing is fixedly installed on the inner wall of the vertical pipe. A first shaft is rotatably connected inside the two first bushings. A cleaning rod is fixedly installed on the surface of the first shaft. A horizontal pipe is fixedly connected to the bottom of the vertical pipe. A second bushing is fixedly installed on the left inner wall of the horizontal pipe. A second shaft is rotatably connected inside the second bushing.

[0003] During use, although the device can drive the cleaning brush to rotate and clean the inside of the pipe through water flow, the water flow inside the pipe will also decrease when the water content inside the foundation decreases. This will weaken the impact force, making it unable to effectively drive the cleaning rod to rotate and unable to effectively remove the sludge from the pipe. Consequently, the cleaning effect of the sludge inside the pipe will be reduced, affecting the drainage effect.

[0004] Therefore, it is necessary to invent a drainage and waterproofing structure for soft soil foundations to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a drainage structure for soft soil foundations, in order to solve the problem that when the water content inside the foundation decreases, the cleaning rod cannot be effectively rotated, and the silt in the pipe cannot be effectively removed, thus reducing the cleaning effect of the silt in the pipe and affecting the drainage effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drainage structure for soft soil foundation, comprising a foundation layer, wherein a drainage shaft, a settling well, and a drainage pipe are pre-embedded inside the foundation layer, and multiple sets of permeable grooves are formed on the surface of the drainage shaft, the settling well is located at the lower end of the drainage shaft, the drainage pipe is located on the left and right sides of the settling well, and a collection bucket that can slide up and down is provided inside the settling well, and a lifting assembly is fixedly installed at the upper end of the foundation layer above the drainage shaft, the lifting assembly including a fixed bracket, a transmission rod, a winding roller, a drive motor, and a lifting cable.

[0007] By adopting the above technical solution, the water inside the foundation layer seeps into the drainage shaft through the permeable trough, and then flows into the settling well. When the water level inside the settling well reaches the height of the drainage pipe, it is discharged to the outside through the drainage pipe. When the water flows into the settling well, the mud and sand in the water will settle inside the collection bucket. At the same time, the collection bucket can be lifted to the top of the drainage shaft by the lifting component to clean the sludge collected inside the collection bucket, thereby effectively preventing sludge from entering the drainage pipe, keeping the drainage pipe unobstructed, and improving the drainage effect.

[0008] Optionally, the fixed bracket is fixedly installed at the upper end of the drainage shaft, and a transmission rod is rotatably connected to the inner side of the fixed bracket. The winding roller is fixedly connected to the middle part of the transmission rod, and the upper end of the lifting cable is fixed to the surface of the winding roller.

[0009] By adopting the above technical solution, the winding roller is used to wind up the lifting cable and raise and lower the collection bucket.

[0010] Optionally, the drive motor is fixedly mounted on the side of the fixed bracket, and the output end of the drive motor is fixedly connected to the rear end of the transmission rod through a coupling.

[0011] By adopting the above technical solution, the output end of the drive motor drives the transmission rod to rotate, and the transmission rod drives the take-up roller to rotate.

[0012] Optionally, the inner walls of the drainage shaft and the settling well are each fixedly connected with two sets of guide rods, and the side of the collection bucket is provided with two sets of positioning grooves, which are engaged with the side of the guide rods.

[0013] By adopting the above technical solution, the internal guide rods are kept aligned vertically during the installation of drainage shafts and settlement shafts.

[0014] Optionally, a first fixing rod is fixedly connected to the upper end of the collection bucket, the lower end of the lifting cable is fixedly connected to the middle of the first fixing rod, and fixing plates are fixedly connected to both ends of the first fixing rod. Two sets of first guide rollers are rotatably connected to the sides of the fixing plates.

[0015] Optionally, the lower surface of the collection bucket is provided with multiple sets of seepage holes, and the lower end of the collection bucket is fixedly connected with two sets of second fixing rods. Both ends of the two sets of second fixing rods are rotatably connected with second guide rollers, and the first guide roller and the second guide roller abut against the side of the guide rod.

[0016] By adopting the above technical solution, during the lifting and lowering process of the collection bucket, the first guide roller and the second guide roller slide up and down close to the side of the guide rod, thereby effectively improving the stability of the collection bucket during the lifting and lowering process.

[0017] Optionally, the upper end of the drainage shaft is fitted with two sets of semi-circular sealing caps.

[0018] By adopting the above technical solution, the sealing cover seals the upper end of the drainage shaft, preventing external impurities from falling into the interior of the drainage shaft. External water can also flow into the interior of the drainage shaft through the gap in the middle of the sealing cover, thus discharging water from the surface of the foundation layer.

[0019] Optionally, a connecting pipe is fixedly connected to the side of the settling well, and a plug pipe is fixedly connected to the end of the drainage pipe, with the plug pipe sleeved on the surface of the connecting pipe.

[0020] By adopting the above technical solution, the insertion pipe and the connecting pipe are used together to fix the drainage pipe and the settlement well, thereby improving the firmness of the connection between the settlement well and the drainage pipe.

[0021] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0022] 1. This utility model uses a permeable trough to allow water from inside the foundation layer to seep into the drainage shaft, and then flow into the settling well. The mud and sand in the water will settle inside the collection bucket. At the same time, the collection bucket can be lifted to the top of the drainage shaft by the lifting component to clean the sludge collected inside the collection bucket, thereby effectively preventing sludge from entering the drainage pipe, keeping the drainage pipe unobstructed, and improving the drainage effect.

[0023] 2. This utility model extends the upper end of the drainage shaft to the upper surface of the foundation layer, so that the water accumulated on the surface of the foundation layer can flow into the interior of the drainage shaft through the gap in the middle of the sealing cover, thereby discharging the water on the surface of the foundation layer, increasing the drainage speed of the foundation layer surface, reducing water infiltration, and maintaining the stability of the foundation layer interior.

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0033] This utility model provides, for example Figures 1 to 4 The diagram shows a soft soil foundation drainage structure, including a foundation layer 1. The foundation layer 1 has a pre-embedded drainage shaft 2, a settling well 3, and a drainage pipe 33. The surface of the drainage shaft 2 has multiple sets of permeable grooves 21. The upper end of the drainage shaft 2 is fitted with two sets of semi-circular sealing caps 22. The settling well 3 is located at the lower end of the drainage shaft 2. The drainage pipe 33 is located on the left and right sides of the settling well 3. A connecting pipe 32 is fixedly connected to the side of the settling well 3. A plug pipe 34 is fixedly connected to the end of the drainage pipe 33, and the plug pipe 34 is sleeved on the surface of the connecting pipe 32. The settling well 3 has a collection bucket 4 that can slide up and down inside. A lifting assembly is fixedly installed on the foundation layer 1 at the upper end of the drainage shaft 2. The lifting assembly includes a fixed bracket 11, a transmission rod 12, a winding roller 13, a drive motor 14, and a lifting cable 15.

[0034] The drainage shaft 2 and the settling well 3 are both customized according to the internal conditions of the foundation layer 1. First, after drilling holes in the foundation layer 1, the drainage shaft 2, the settling well 3, and the drainage pipe 33 are pre-embedded inside. Then, the lifting component is installed at the upper end of the drainage shaft 2, and the collection bucket 4 is placed inside the settling well 3. During use, the water inside the foundation layer 1 seeps into the drainage shaft 2 through the permeable trough 21, and then collects in the settling well 3. When the water level of the collected water reaches the height of the drainage pipe 33, it is discharged outward through the drainage pipe 33. The collected water will settle inside the settling well 3, and the silt inside it will settle into the collection bucket 4, preventing silt from entering the drainage pipe 33, reducing silt accumulation inside the drainage pipe 33, and effectively improving the drainage effect.

[0035] See Figure 1 and Figure 2The fixed bracket 11 is fixedly installed at the upper end of the drainage shaft 2. The transmission rod 12 is rotatably connected to the inner side of the fixed bracket 11. The winding roller 13 is fixedly connected to the middle part of the transmission rod 12. The upper end of the lifting cable 15 is fixed to the surface of the winding roller 13. The drive motor 14 is fixedly installed on the side of the fixed bracket 11. The output end of the drive motor 14 is fixedly connected to the rear end of the transmission rod 12 through a coupling.

[0036] In addition, when the silt inside the collection bucket 4 accumulates to a certain extent, the collection bucket 4 is lifted to the upper end of the drainage shaft 2 by the lifting component to clean the silt inside the collection bucket 4. Specifically, during the silt cleaning process, the drive motor 14 is started, and the output end of the drive motor 14 drives the transmission rod 12 to rotate. The transmission rod 12 drives the winding roller 13 to rotate, and the winding roller 13 winds up the lifting cable 15, thereby lifting the collection bucket 4 upward. Conversely, the collection bucket 4 is placed downward inside the settling well 3.

[0037] See Figures 3 to 6 Two sets of guide rods 31 are fixedly connected to the inner walls of the drainage shaft 2 and the settling shaft 3. Two sets of positioning grooves 44 are opened on the side of the collection bucket 4. The positioning grooves 44 are locked on the side of the guide rods 31. The upper end of the collection bucket 4 is fixedly connected to the first fixing rod 41. The lower end of the lifting cable 15 is fixedly connected to the middle of the first fixing rod 41. The two ends of the first fixing rod 41 are fixedly connected to the fixing plates 42. Two sets of first guide rollers 43 are rotatably connected to the side of the fixing plates 42. Multiple sets of seepage holes 45 are opened on the lower surface of the collection bucket 4. Two sets of second fixing rods 46 are fixedly connected to the lower end of the collection bucket 4. The two ends of the two sets of second fixing rods 46 are rotatably connected to the second guide rollers 47. The first guide rollers 43 and the second guide rollers 47 abut against the side of the guide rods 31.

[0038] In addition, during the lifting and lowering process, the first guide roller 43 and the second guide roller 47 slide up and down close to the surface of the guide rod 31, which improves the stability of the collection bucket 4 during the lifting and lowering process. At the same time, since the lower end of the collection bucket 4 is provided with a seepage hole 45, the collection bucket 4 can quickly sink to the bottom of the settling well 3.

[0039] The working principle of this utility model is as follows: Water from the base layer 1 seeps into the drainage shaft 2 through the permeable trough 21, and then flows into the settling well 3. The mud and sand in the water will settle into the collection bucket 4. At the same time, the collection bucket 4 can be lifted to the top of the drainage shaft 2 by the lifting component to clean the sludge collected in the collection bucket 4, thereby effectively preventing sludge from entering the drainage pipe 33, keeping the drainage pipe 33 unobstructed, and improving the drainage effect. At the same time, by extending the upper end of the drainage shaft 2 to the upper surface of the base layer 1, the water accumulated on the surface of the base layer 1 can flow into the drainage shaft 2 through the gap in the middle of the sealing cover 22, discharging the water on the surface of the base layer 1, increasing the drainage speed of the surface of the base layer 1, reducing water seepage, and maintaining the stability of the base layer 1.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
