Description

Technical Field

[0001] This utility model belongs to the field of soft soil foundation drainage technology, specifically relating to a combined drainage device based on soft soil foundation. Background Technology

[0002] Drainage of soft soil foundations is a common engineering problem in soft soil areas. This is mainly due to the high water content, low strength, and high compressibility of soft soil, which makes the foundation prone to uneven settlement under load, affecting the safety and stability of buildings. Drainage devices are required when draining soft soil foundations.

[0003] Chinese utility model patent CN206941570U discloses a drainage structure for soft soil foundations. This structure involves setting a drainage body within the soft soil foundation, with radially sliding drainage components and a driving component that drives the drainage components to extend radially out of the drainage body. While it has the advantage of a wide radiation range from a single drainage body, it lacks the function of filtering the discharged water. Therefore, the water discharged from the soft soil layer easily contains a large amount of silt, which cannot be removed for reuse, resulting in water waste. Furthermore, direct discharge into ditches can easily affect the water quality of other water sources. Moreover, it lacks a convenient function for cleaning the filtered silt, leaving residue inside the tank that is inconvenient to drain and clean, thus affecting cleaning efficiency.

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1 , Figure 2The diagram illustrates a combined drainage device based on soft soil foundation, comprising a base plate 1 and insert cylinders 8. A filter box 3 is bolted to the top of the base plate 1. A pusher assembly 2 and a filter assembly 9 are installed inside the filter box 3. A filter screen cylinder 10 is installed inside the insert cylinder 8. Through holes are provided on the side walls of the insert cylinder 8. The insert cylinder 8 is inserted into the soft soil foundation. Water in the soft soil foundation first enters the insert cylinder 8 through the through holes in the side walls, and then undergoes preliminary filtration by the filter screen cylinder 10 before entering its interior. A suction pump 6 and a vacuum pump 11 are bolted to the left side of the top of the base plate 1. A connecting pipe 7 is fixedly connected to the water inlet of the suction pump 6 and the air inlet of the vacuum pump 11. A water suction pipe 13 and an air suction pipe 12 are respectively installed through the front and rear sides of each insert cylinder 8. A delivery pipe 5 is fixedly connected to the water outlet of the suction pump 6.

[0026] Please see Figure 1 , Figure 4 and Figure 6 The feeding assembly 2 includes a drive motor 201. The rear side of the drive motor 201 is fixedly connected to the front side of the filter box 3 by bolts. The inner cavity of the filter box 3 is connected to a square shell 202 by bolts. The rear end of the square shell 202 extends through to the back side of the filter box 3. The end of the conveying pipe 5 away from the suction pump 6 extends through to the inner cavity of the filter box 3 and is fixedly connected to the top of the square shell 202. The rear end of the drive motor 201 shaft extends through to the inner cavity of the square shell 202 and is welded with a feeding auger 204.

[0027] Please see Figure 1 , Figure 4 and Figure 6 A sealing cover 203 is fitted at the rear end of the square shell 202. Short plates 205 are welded on both the left and right sides of the square shell 202. An elastic buckle 206 is welded on the front of the sealing cover 203. By setting the elastic buckle 206, it is easy to fix the sealing cover 203 to the rear end of the square shell 202 for sealing, and it is also easy to remove it. An installation hole is opened at the bottom of the square shell 202.

[0028] Please see Figure 4 and Figure 5 The filter assembly 9 includes a telescopic rod 902. One end of the telescopic rod 902 is fixedly connected to the inner cavity of the filter box 3 by bolts. A circular plate 905 is welded to the other end of the telescopic rod 902. A connecting spring 907 is movably sleeved on the surface of the telescopic rod 902. The two ends of the connecting spring 907 are respectively welded to the inner wall of the filter box 3 and the surface of the circular plate 905.

[0029] Please see Figure 4 and Figure 5A short rod 906 is welded to the side of the circular plate 905 away from the telescopic rod 902. A filter screen plate 901 is provided on the surface of the short rod 906. A push rod 904 is welded to the bottom of the circular plate 905. A support plate 903 is welded to the surface of the push rod 904. By setting the support plate 903, the filter screen plate 901 can be supported, thereby ensuring the stability of the installation of the filter screen plate 901.

[0030] Please see Figure 1 and Figure 3 The bottom of the base plate 1 is bolted to a rod 4. The rod 4 is used to fix the base plate 1 to the ground to prevent it from moving. The bottom ends of the front connecting pipe 7 and the rear connecting pipe 7 are fixedly connected to the top of the water suction pipe 13 and the air suction pipe 12, respectively. The top of the insert 8 is bolted to a circular sealing plate. The right side of the filter box 3 is bolted to a sealing baffle. The bottom right side of the filter box 3 is fixedly connected to a drain pipe.

[0031] In use, an external controller and power supply are connected, the device is inserted into the soft soil foundation, and a sealing film is laid on the surface to seal it. Vacuum pump 11 operates, drawing a vacuum into the soft soil foundation through the rear connecting pipe 7 and suction pipe 12, creating negative pressure within the soft soil layer. This allows water from the soft soil layer to enter the insert 8. As the water enters the insert 8, it is filtered through the filter screen 10. Simultaneously, suction pump 6 operates, drawing water through its connecting pipe 7 and suction pipe 13, thus solidifying the soft soil foundation. The drawn water enters the filter box 3, where it is filtered through the filter screen 901, further improving water quality. It may affect other water sources, but it also facilitates water utilization. During filtration, the drive motor 201 can drive the pusher auger 204 to rotate, allowing the filtered sediment to move to the rear of the inner cavity of the square shell 202. When discharge is required, push the elastic buckle 206 to remove the sealing cover 203, and drive the drive motor 201 to rotate the pusher auger 204 again, thus facilitating the discharge of sediment. When the filter screen 901 needs to be removed, push the push rod 904 to retract the connecting spring 907, allowing the short rod 906 to disengage from the mounting hole at the end of the filter screen 901, thereby removing the filter screen 901.
