Description

Technical Field

[0001] The utility model relates to the technical field of soft soil foundation anti-drainage structures, in particular to an anti-clogging soft soil foundation anti-drainage structure. Background Technique

[0002] Soft soil refers to fine-grained soil deposited in coastal areas, lakes, valleys, and river beaches, which has high natural water content, large void ratio, high compressibility, and low shear strength. It has the characteristics of high natural water content, large natural void ratio, high compressibility, low shear strength, small consolidation coefficient, long consolidation time, high sensitivity, large disturbance, poor water permeability, complex layered distribution of soil layers, and significant differences in physical and mechanical properties between layers. The foundation of this kind of soil is prone to settlement, so it is necessary to reinforce the foundation.

[0003] At present, the soft soil foundation treatment methods widely used in engineering mainly include two categories: physical methods and chemical methods. Physical methods include dynamic compaction, vacuum preloading, surcharge preloading, etc. These methods are based on the basic mechanisms of mechanical reinforcement and soil consolidation. However, due to the large water content in the soft soil foundation, the permeable pile foundations inserted into the soft soil are easily blocked by the soft soil, thus reducing the seepage efficiency of the permeable pile foundations.

[0004] Chinese Patent CN202121290089.1 discloses "A Soft Soil Foundation Anti-Drainage Structure", with the publication number CN214783809U. The device includes a base, an installation plate is placed on the base, a lifting component for driving the installation plate to move vertically is installed on the base, a drainage component is installed below the installation plate. The drainage component includes a permeable filter pipe detachably connected to the lower end face of the installation plate and a water collecting pipe placed in the permeable filter pipe. Both the permeable filter pipe and the water collecting pipe are vertically arranged. A driving component for driving the water collecting pipe to rotate is installed on the installation plate, and a cleaning component for cleaning the permeable filter pipe is installed on the water collecting pipe. However, this device has some defects: the device uses a brush structure to clean the filter holes, but the cleaning of the filter holes by the brush is not thorough, and part of the soft soil will remain inside the filter holes. Content of the Utility Model

[0005] In order to solve the above problems of the prior art, the utility model provides an anti-clogging soft soil foundation anti-drainage structure, which can thoroughly clean the soft soil in the filter holes and avoid the soft soil remaining in the filter holes.

[0006] To achieve the above object, the present utility model provides the following technical solution: An anti-blocking drainage structure for soft soil foundation, including a permeable pipe provided with filter holes and a cleaning device for cleaning the filter holes.

[0012] Preferably, a cleaning plate is fixedly connected to the cleaning rod, and a plurality of cleaning columns matching the filter holes are fixedly connected to the cleaning plate.

[0013] With the above structural design, one cleaning rod can clean multiple filter holes at the same time, which can reduce the number of cleaning rods, reduce the components of the device, and save resources and costs.

[0023] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 , the present utility model provides a technical solution: an anti-blocking soft soil foundation anti-drainage structure, including a permeable pipe 1 provided with filter holes 11 and a cleaning device for cleaning the filter holes 11. A sealing cover 12 is provided at the lower end of the permeable pipe 1, and a drain pipe 13 is communicated with the pipe wall of the permeable pipe 1; the cleaning device includes a cleaning rod 21 matching the filter holes 11, a support pipe 22 arranged inside the permeable pipe 1, a blocking plate 23 fixedly connected to the tail end of the cleaning rod 21, and a driving component for driving the blocking plate 23 to move. A plurality of cleaning rods 21 are provided, and the cleaning rods are arranged in a circular array along the center of the permeable pipe 1. The cleaning rod 21 penetrates through the pipe wall of the support pipe 22, and the support pipe 22 is fixedly connected to the permeable pipe 1 through an inner support rod 29.

[0024] During use, the drain pipe 13 is communicated with a water pump to continuously discharge the permeated water inside the permeable pipe 1.

[0025] The driving component includes an airbag 31 arranged inside the baffle 23, an air pump 32 communicating with the airbag, an exhaust pipe 33 communicating with the airbag 31, and a return spring 34 arranged between the outer wall of the baffle 23 and the support pipe 22. The return spring 34 is sleeved on the cleaning rod 21. The head end of the return spring 34 is fixedly connected to the inner wall of the support pipe 22, and the tail end of the return spring 34 is fixedly connected to the baffle 23. An electric valve 35 is fixedly connected to the exhaust pipe 33, and both the air pump 32 and the electric valve 35 are electrically connected to a controller 36.

[0026] When the airbag is used for the first time, the air pump 32 takes a relatively long time to fill the deflated airbag 31 and expand it, pushing the baffle 23 to move. When the cleaning rod 21 penetrates through the filter hole 11, the air pump 32 stops operating, and the electric valve 35 opens. Under the action of the return spring 34, the cleaning rod 21 gradually withdraws from the filter hole 11, and the electric valve 35 closes. After an interval of time, the air pump 32 operates again. Since there is residual air in the airbag, the airbag 31 is quickly filled. By repeating the above steps cyclically, the cleaning rod 21 will regularly dredge the filter hole 11.

[0027] In order to increase the accuracy of the cleaning rod 21 entering the filter hole 11, a guiding sleeve 39 is sleeved on the cleaning rod 21, and the guiding sleeve 39 is fixedly connected to the support pipe 22.

[0028] The water-permeable pipe 1 is flange-connected to the base plate 4. The upper end of the water-permeable pipe 1 is fixedly connected to a flange ring. The air pump 32 is fixedly connected to the base plate 4, and the exhaust pipe 33 penetrates through the base plate 4.

[0029] A cleaning plate 211 is fixedly connected to the cleaning rod 21, and a plurality of cleaning columns 212 matching the filter holes 11 are fixedly connected to the cleaning plate 211. The number of the filter holes 111 matches the number of the cleaning columns 212.

[0030] A conical guiding block 15 is fixedly connected to the lower end of the sealing cover 12, and the sealing cover 12 is threadedly connected to the water-permeable pipe 1.

[0031] When the device is in use, first, the staff installs the sealing cover 12 at the lower end of the water-permeable pipe 1, and then the staff inserts the device into the soft soil foundation.

[0032] Next, the staff starts the cleaning device. The air pump 32 begins to operate, the electric valve 35 closes, the exhaust pipe 33 is in a closed state, the airbag 31 expands fully, pushing the blocking plate 23 to move. When the cleaning rod 21 and the cleaning column 212 penetrate through the filtering holes 11, the air pump 32 stops operating, the electric valve 35 opens, and the exhaust pipe 33 is in an open state. Under the action of the return spring 34, the cleaning rod 21 gradually withdraws from the filtering holes 11, the electric valve 35 closes, and after a period of time, the air pump 32 operates again, repeating the above steps in a cycle. The cleaning rod 21 will regularly dredge the filtering holes 11.
