Abstract
Description
Technical Field
[0001] This utility model relates to a drainage structure for soft soil foundations, belonging to the field of soft soil foundation treatment technology. Background Technology
[0002] Soft soil foundations require drainage treatment. Multiple drainage pipes with perforated drainage holes are inserted into the foundation. These pipes are then connected to a vacuum system via connecting pipes. When the vacuum system operates, it creates negative pressure within the pipes, causing moisture in the soft soil to collect through the perforations. The water is then expelled by the vacuum system. Because a large number of drainage pipes are inserted into the soft soil foundation, and their positions may differ, flexible hoses are installed on the top caps of the pipes to facilitate connection. The adjustable hoses allow for easy connection between pipes at different locations. However, this presents a problem: during storage, the multiple pipes and hoses can easily become entangled and compressed, hindering separation. Therefore, a drainage structure for soft soil foundations needs to be designed to prevent entanglement and compression of the hoses during stacking. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a drainage structure for soft soil foundation to solve the problems mentioned in the background technology. This utility model prevents the hoses from getting tangled and squeezed together during the stacking of multiple drainage pipes.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a drainage structure for soft soil foundations, comprising a drainage pipe, a pointed end fixedly connected to the lower end of the drainage pipe, multiple seepage holes evenly distributed on the outer surface of the drainage pipe, a filter cylinder for intercepting sediment inserted inside the drainage pipe, a top cover threadedly connected to the upper end of the drainage pipe, a flexible hose for connecting to the inlet end of a vacuum tank installed on the upper surface of the top cover, a pressure plate fixedly connected to the drainage pipe and fitted onto the upper end of the drainage pipe, a movable disc located below the pressure plate and fitted onto the drainage pipe. Both the pressure plate and the movable plate have symmetrically arranged first and second planes machined on their annular sides. A countersunk screw hole is provided in the middle of the first plane on the movable plate. An internal hexagon screw for limiting the relative position of the movable plate and the drain pipe is connected to the countersunk screw hole. Both the pressure plate and the movable plate have notches for storing hoses. Both the pressure plate and the movable plate have mating hook and loop fasteners attached to their annular sides. The hook and loop fasteners are respectively located on both sides of the notch.
[0005] Furthermore, two symmetrically arranged insertion holes are provided on the first plane, and two insertion posts that mate with the insertion holes are installed on the second plane. The insertion posts in the lower drain pipe are inserted into the insertion holes in the upper drain pipe.
[0006] Furthermore, an annular stepped groove is machined at the end of the insertion post away from the second plane, and a rubber sleeve is pasted inside the annular stepped groove. The outer diameter of the rubber sleeve is the same as the inner diameter of the insertion hole.
[0007] Furthermore, two threaded blind holes are symmetrically opened on the second plane, and one end of the plug is machined with an external thread, and the end of the plug with the external thread is threadedly connected to the threaded blind hole.
[0008] Furthermore, a pipe connector is installed at the center of the upper surface of the top cover, one end of the hose is connected to the pipe connector, a branch pipe is installed at the end of the hose away from the pipe connector, and a flange is installed at the end of the branch pipe away from the hose.
[0009] Furthermore, a connecting sleeve is fixedly connected to the side of the pressure plate facing the movable plate, and the connecting sleeve is sleeved on the drain pipe and fixedly connected to the drain pipe.
[0010] The beneficial effects of this utility model are:
[0011] 1. Insert the drain pipe into the soft soil foundation, and then connect the hose to the connecting pipe on the vacuum tank. Under the action of the vacuum machine, a vacuum is formed in the vacuum tank. At this time, a negative pressure is also formed in the drain pipe, so that the water in the soft soil foundation seeps into the drain pipe after being filtered by the filter cartridge. Then the water flows into the vacuum tank through the channel formed by the hose and the connecting pipe, thus realizing the drainage of the soft soil foundation.
[0012] 2. Place the movable disc onto the drain pipe and use the Allen screws to restrict the relative position of the movable disc and the drain pipe, making it easy to assemble and disassemble the movable disc and the drain pipe. The movable disc can be removed during the use of the drain pipe.
[0013] 3. Place the hollow pressure head on the upper end of the drainage pipe until the lower end of the pressure head contacts the pressure plate, so that the upper end of the drainage pipe with external threads will not be damaged when the drainage pipe is inserted into the soft soil foundation using the extrusion equipment.
[0014] 4. Insert the hose into the two notches, and then stick the hook and loop sides of the Velcro together to confine the hose within the notches. This allows the hose to be arranged along the length of the drain pipe, thus restricting its position and preventing it from becoming tangled or squeezed during storage.
[0015] 5. Insert the plugs on the lower pressure plate and the movable plate into the corresponding plug holes on the upper pressure plate and the movable plate respectively to achieve stable connection of the drainage pipes on both sides. Repeat this process to complete the neat stacking of multiple drainage pipes. Attached Figure Description

Detailed Implementation
[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a drainage structure for soft soil foundation, including a drainage pipe 1, with a fixed tip 16 connected to the lower end of the drainage pipe 1 to reduce the resistance of the drainage pipe 1 when inserted into the soft soil foundation.
[0024] See Figure 1 , Figure 2 and Figure 4The outer surface of the drain pipe 1 is evenly provided with multiple seepage holes 15. A filter cylinder 22 for intercepting mud and sand is installed inside the drain pipe 1. The upper end of the drain pipe 1 is threaded with a top cover 5. A hose 6 for connecting to the liquid inlet of the vacuum tank is installed on the upper surface of the top cover 5. A pipe connector 9 is installed in the middle of the upper surface of the top cover 5. One end of the hose 6 is connected to the pipe connector 9. A branch pipe 7 is installed at the end of the hose 6 away from the pipe connector 9. A flange 8 is installed at the end of the branch pipe 7 away from the hose 6. The drain pipe 1 is inserted into the soft soil foundation. Then the hose 6 is connected to the connecting pipe on the vacuum tank. Under the action of the vacuum machine, a vacuum is formed in the vacuum tank. At this time, a negative pressure is also formed in the drain pipe 1, so that the water in the soft soil foundation seeps into the drain pipe 1 after being filtered by the filter cylinder 22. Then the water flows into the vacuum tank through the channel formed by the hose 6 and the connecting pipe, realizing the drainage of the soft soil foundation.
[0025] See Figure 1 , Figure 2 and Figure 4 The upper end of the drain pipe 1 is fitted with a pressure plate 10 that is fixed to the drain pipe 1. The side of the pressure plate 10 facing the movable plate 12 is fixed to a connecting sleeve 2. The connecting sleeve 2 is fitted onto the drain pipe 1 and fixed to the drain pipe 1. The connecting sleeve 2 increases the connection range between the pressure plate 10 and the drain pipe 1, so that the hollow pressure head is fitted onto the upper end of the drain pipe 1 until the lower end of the pressure head contacts the pressure plate 10. Thus, when the drain pipe 1 is inserted into the soft soil foundation using the extrusion equipment, the upper end of the drain pipe 1 with external threads is not damaged.
[0026] See Figures 1-3 A movable plate 12 is provided on the lower side of the pressure plate 10. The movable plate 12 is sleeved on the drain pipe 1. A first plane 4 and a second plane 20 are symmetrically arranged on the annular side of the pressure plate 10 and the annular side of the movable plate 12. A countersunk screw hole 21 is opened in the middle of the first plane 4 on the movable plate 12. An internal hexagon screw 17 is connected to the countersunk screw hole 21 to limit the relative position of the movable plate 12 and the drain pipe 1. The movable plate 12 is sleeved on the drain pipe 1, and the internal hexagon screw 17 limits the relative position of the movable plate 12 and the drain pipe 1, which facilitates the disassembly and assembly of the movable plate 12 and the drain pipe 1. The movable plate 12 can be removed during the use of the drain pipe 1.
[0027] See Figures 1-4Both the pressure plate 10 and the movable plate 12 have notches 11 for storing the hose 6. Both the pressure plate 10 and the movable plate 12 have matching hook and loop fasteners 14 and 13 respectively attached to their respective sides. The hook and loop fasteners 14 and 13 are respectively located on both sides of the notch 11, so that the hose 6 can be inserted into the two notches 11. Then the 13 is attached to the hook and loop fasteners 14, thereby restricting the hose 6 within the notch 11. This allows the hose 6 to be arranged along the length of the drain pipe 1, thus restricting the position of the hose 6 and preventing the hose 6 from getting tangled and squeezed during storage.
[0028] See Figure 1 and Figure 2 The end of the plug post 18 away from the second plane 20 is machined with an annular stepped groove. A rubber sleeve 19 is attached inside the annular stepped groove. The outer diameter of the rubber sleeve 19 is the same as the inner diameter of the plug hole 3. The rubber sleeve 19 increases the friction coefficient between the plug post 18 and the inner wall of the plug hole 3. Two threaded blind holes are symmetrically opened on the second plane 20. One end of the plug post 18 is machined with an external thread, so that the end of the plug post 18 with the external thread is threaded into the threaded blind hole, which facilitates the assembly and disassembly of the plug post 18.
[0029] See Figures 1-4 Two symmetrically arranged insertion holes 3 are provided on the first plane 4, and two insertion posts 18 that cooperate with the insertion holes 3 are installed on the second plane 20. The insertion posts 18 in the lower drainage pipe 1 are inserted into the insertion holes 3 in the upper drainage pipe 1. That is, the insertion posts 18 on the lower pressure plate 10 and the movable plate 12 are respectively inserted into the corresponding insertion holes 3 on the upper pressure plate 10 and the movable plate 12, so as to realize the stable insertion of the drainage pipes 1 on adjacent sides. In this way, multiple drainage pipes 1 are neatly stacked.
