Description

Technical Field

[0001] The invention relates to the technical field of foundation drainage, in particular to a drainage structure for treating soft soil foundation. Background Art

[0002] For soft foundation treatment, the commonly used methods currently include vacuum preloading, dynamic tamping, pile foundation, etc. Different treatment methods are suitable for different types of soft soil. Vacuum preloading is mainly used in soft soil areas with high compressibility and high water content, but vacuum preloading is time-consuming and requires full-area construction, and the cost is relatively high. Prefabricated pipe piles have high pile body strength and are widely used for quick construction. They mainly rely on their own pile end bearing capacity and pile side friction resistance to improve the foundation bearing capacity. Currently, they are mainly suitable for medium and low compressible foundations. After searching, the Chinese patent publication number CN208949870U discloses a prefabricated pipe pile vacuum drainage structure for soft soil foundation treatment. The vacuum drainage structure includes a prefabricated pipe pile, a vacuum pump and a water pump. A plurality of drainage holes are opened on the pile body of the prefabricated pipe pile, and a filter plug is provided at the position of each drainage hole; the lower end of the prefabricated pipe pile extends below the clay layer of the soft soil foundation.

[0003] The above technical solution combines a vacuum system and a drainage system. Although it can perform vacuum drainage consolidation to achieve the purpose of improving the bearing capacity of the foundation and shortening the construction period, it is suitable for medium and high compression soft soil areas. However, in actual use, the depth of the soft soil foundation is often different. Using corresponding prefabricated pipes each time will not only increase the production and use costs, but also increase the workload. The vacuum cannot be adjusted according to the drainage depth of the soft soil foundation, and it is easy to be punctured by sharp objects in the foundation during penetration and filtration through the geotextile. Since it is inconvenient to maintain and replace it underground, soil leakage occurs, affecting the drainage effect. Moreover, the water pump is installed in the prefabricated pipe, and the prefabricated pipe needs to be pulled out before the pile hole can be filled. Not only is the operation cumbersome, but it is also prone to collapse, affecting construction. Summary of the Invention

[0051] Example 5:

[0052] like Figure 9 and Figure 10 As shown, a pumping mechanism 10 is installed between the upper surface of the vehicle body 1 and the blocking mechanism 9. The pumping mechanism 10 includes a water tank 101 fixedly installed on the upper surface of the vehicle body 1, and a water pump 102 is fixedly installed on the top of the water tank 101. The output end of the water pump 102 is connected to the interior of the water tank 101, and the input end of the water pump 102 is fixedly connected to a water pump hose 103. The upper surface of the conical head 95 is fixedly connected to a water pipe 104.

The water inlet trough 105 is provided to facilitate the water to enter the water pipe 104.

[0054] Working principle: When in use, first move the vehicle body 1 to move the entire structure to the soft soil foundation that needs to be drained, then start the first motor 21 according to the required drainage depth to insert the infiltration tube 3 into the soft soil foundation, and then start the first cylinder 52 according to the insertion depth. The operation of the first cylinder 52 can drive the piston plate 53 to move up and down, so that the number of infiltration holes 6 opened can be adjusted according to the insertion depth of the infiltration tube 3, avoiding affecting the vacuum effect and saving energy, thereby solving the problem that the existing device cannot adjust the vacuum position according to the insertion depth of the pipe and is prone to incomplete insertion and leakage, and then start the suction pump 51 to vacuum the infiltration tube 3. At this time, the water in the soft soil foundation will flow from the infiltration part to the inside of the infiltration tube 3, and then start the water pump 102. The water pump 102 can run through the water suction hose 103 and the water pipe 104 to extract the infiltrated water and discharge it into the water tank 101, thereby achieving the drainage effect of the soft soil foundation. The water inlet trough 105 is provided to facilitate water to enter the water pipe 104, thereby achieving the drainage operation of the soft soil foundation.

[0055] During the drainage process, the camera can shoot the situation inside the permeation tube 3, which is convenient for observation. When the permeation piece is punctured and damaged, the second cylinder 81 can drive the ring 82 to rise and fall, and then start the corresponding electric push rod 84, so that the intact permeation piece can be inserted into the corresponding permeation hole 6 and the damaged permeation piece can be pushed out, so that quick maintenance can be carried out, thereby solving the problem that the existing device cannot replace the filter plug.

[0056] After the drainage is completed, the first cylinder 52, the second cylinder 81 and the second motor 92 are started to respectively raise the piston plate 53, the ring 82 and the conical head 95 to the top of the grouting pipe 111, connect the connecting head 112 to the external grouting equipment, and then open the second control valve 113 to carry out the grouting operation into the permeable tube 3. Then, the permeable tube 3 can be taken out after the grouting is completed, which not only avoids waste but also avoids collapse, thereby solving the problem that the existing device is inconvenient to fill the holes caused by piling.
