[0002] Soft soil foundation is mainly composed of soft soil with high content of fine particles such as clay and silt, organic soil with large pores, peat and loose sand. The groundwater level is high, and the fill and structures on it are unstable and the foundation is subsiding. The purpose of soft soil roadbed treatment is to improve the stability and bearing capacity of the roadbed of this section of highway. Soft soil foundation, especially silt soil, has a very low foundation bearing capacity due to its high water content, large pores and high compressibility of the soil. At present, the replacement method, preloading method and various replacement methods are often used in engineering to treat soft soil foundation.

[0003] When existing columns are driven into the ground, the small cross-sectional area of ​​the columns causes the supporting area for soft soil to become smaller, resulting in a relatively low supporting effect. When subjected to gravity, the land around the columns is prone to the risk of sinking, resulting in an unstable foundation and causing the foundation to collapse and be damaged. In order to solve the above-mentioned problems, the utility model provides a soft soil foundation reinforcement structure. Utility Model Content

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0018] like Figure 1-3 As shown, a soft soil foundation reinforcement structure proposed in one embodiment of the utility model comprises: a column 1, a plurality of openings are opened on both sides of the column, and a plurality of through openings are constructed on the column 1;

[0019] A plurality of reinforcing plates 2, each two of which form a group, are symmetrically distributed and slidably installed between the two sides of the inner wall of the column 1, and the plurality of reinforcing plates 2 correspond to the plurality of openings one by one;

[0020] A moving component 3 is installed inside the column 1, and is used to drive the multiple reinforcement plates 2 to move horizontally. The moving component 3 includes a rotating rod 31 rotatably installed at the bottom of the inner wall of the column 1, and two rotating plates 32 are rotatably installed on one side of the reinforcement plate 2. A plurality of bidirectional threads 33 are constructed on the rotating rod 31, and each of the bidirectional threads 33 is symmetrically threaded with two moving plates 34, and the moving plate 34 is rotatably connected to the rotating plate 32.

[0021] First, the column 1 is driven into the soft soil foundation. The sliding installation between the reinforcement plate 2 and the two sides of the inner wall of the column 1 facilitates the reinforcement plate 2 to be moved out of the openings on both sides of the column 1 to form a symmetrically distributed reinforcement structure. The moving component 3 is installed inside the column 1. Its main function is to drive the reinforcement plate 2 to move horizontally out of the column 1. The moving component 3 includes a rotating rod 31, which is installed at the bottom of the inner wall of the column 1, and a rotating plate 32 is installed on one side of the reinforcement plate 2. The rotating rod 31 is provided with a plurality of bidirectional threads 33, and each bidirectional thread 33 is symmetrically installed with two moving plates 34. , the movable plate 34 is connected to the rotating plate 32 by rotation. When an external driving member, such as the top of the rotating rod 31 is fixed to the output end of the motor to drive the rotating rod 31 to rotate, the bidirectional thread 33 will drive the two movable plates 34 to move closer to each other along the upper and lower thread directions, thereby driving the two rotating plates 32 on one side of the reinforcing plate 2 to gradually fold closer, and then the reinforcing plate 2 can be pushed horizontally through the opening to move out of the column 1 and insert into the soft soil, so as to adjust the relative position of the reinforcing plate 2 in the column 1, increase the transverse cross-sectional area of ​​the column 1, increase its support area, and reinforce the soft soil foundation. In this way, the reinforcement structure can adjust the position of the reinforcing plate 2 as needed to meet the reinforcement needs, thereby achieving the purpose of reinforcing the soft soil foundation. After the insertion is completed, the concrete can be injected into the column 1 through the opening at the top, and then discharged through the openings on both sides of the column 1, mixed with the soft soil, and wait for solidification, so as to realize the concrete pouring inside the soft soil, and improve the reinforcement effect.

[0022] like Figure 1 As shown, in some embodiments, a plurality of inclined plates 4 are fixedly mounted on both sides of the column 1, and the plurality of inclined plates 4 are distributed in a linear array.

[0023] After the inclined plate 4 and the column 1 are driven into the soft soil together, due to the characteristics of the soft soil, the space filled when the inclined plate 4 moves downward will be closed and filled, so that the inclined plate 4 can increase the contact area with the soft soil, increase the support area, and strengthen the soft soil foundation.

[0024] like Figure 3 As shown, in some embodiments, a fixing block 5 is fixedly installed on the top of the rotating rod 31, and the fixing block 5 passes through the column 1 and extends to the outside thereof. A positioning plate 6 is inserted on the fixing block 5, and a groove is constructed on the column 1, and both ends of the positioning plate 6 are inserted in the groove.

[0025] When the rotating rod 31 is rotated, the positioning plate 6 can be inserted into the fixing block 5, and then the two ends of the positioning plate 6 can be inserted into the grooves for limited fixing, so that the rotating rod 31 can be positioned and fixed to prevent it from being affected by external things and causing the rotating rod 31 to rotate, thereby affecting the fixation of the reinforcement plate 2.

[0026] like Figure 2 As shown, in some embodiments, a water collecting box 7 is fixedly installed at the bottom of the column 1, and a drainage pipe 8 is fixedly inserted on the column 1. One end of the drainage pipe 8 passes through the movable plate 34 and the column 1 and extends to the inside of the water collecting box 7. A water inlet is provided in the water collecting box 7. Geotextiles 9 are fixedly installed on the inner circumference of the water collecting box 7.

[0027] A water collecting tank 7 is fixedly installed at the bottom of the column 1. The water collecting tank 7 is used to collect and store water discharged from the soft soil foundation. A drainage pipe 8 is fixedly inserted on the column 1. One end of the drainage pipe 8 passes through the movable plate 34 and the column 1 and extends to the inside of the water collecting tank 7. This design allows the water in the soft soil foundation to be effectively guided and discharged from the water collecting tank 7 through the drainage pipe 8. The water in the water collecting tank 7 can be discharged by a suction pump in conjunction with the drainage pipe 8. A geotextile 9 is fixedly installed on the inner peripheral side of the water collecting tank 7. The function of the geotextile 9 is to prevent soil particles from flowing into the water collecting tank 7 with water, while allowing water to enter the water collecting tank 7 through the geotextile 9. This can not only maintain the drainage performance of the soft soil foundation, but also prevent the inside of the water collecting tank 7 from being blocked due to the accumulation of soil particles. The reinforcement structure not only realizes the reinforcement of the soft soil foundation through the reinforcement plate 2 and the movable component 3, but also realizes the effective collection and discharge of water through the water collecting tank 7 and the drainage pipe 8. The use of the geotextile 9 further improves the performance of the drainage system and ensures the long-term stability and reliability of the soft soil foundation reinforcement project.

[0028] like Figure 2 As shown, in some embodiments, two plug plates 10 are fixedly installed at the bottom of the water collecting tank 7.

[0029] The function of the inserting plate 10 is to increase the area of ​​the column 1 inserted into the soft soil, thereby improving the stability of the reinforced structure and further improving the reinforcement effect.

[0030] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
