Description

Technical Field

[0001] This utility model relates to the field of soft soil foundation improvement technology, specifically a soft soil foundation reinforcement device. Background Technology

[0002] So-called soft soil foundation refers to the relatively loose soil encountered during construction. If not treated in time, it may lead to land collapse and even safety accidents. When improving soft soil foundations, fly ash concrete piles are often used. Fly ash concrete piles are composed of fly ash, crushed stone, medium and coarse sand and cement. In soft soil areas, drilling and grouting technology is used. When constructing fly ash concrete piles, the grouting device is first inserted into the soil and then grouting is performed. When the existing device is inserted into the soil, soft soil can accumulate in the grouting hole and cause blockage of the grouting hole, preventing the grout from flowing out of each grouting hole smoothly, resulting in poor grout penetration.

[0003] According to Chinese patent document CN215669447U, a soft soil foundation reinforcement and improvement device is disclosed. By rotating the handle, the baffle is moved until it covers the grouting hole. Then, the grouting body is inserted into the soft soil. Rotating the baffle again causes the arc-shaped plate to rotate with it. When the arc-shaped plate rotates, the soil around the grouting body is spread out by the compression of the arc-shaped plate, so that the grouting hole will not come into contact with the soil and become blocked. After grouting is completed, the baffle is rotated until it covers the grouting hole, and then the grouting body is pulled out. This effectively avoids grouting hole blockage and increases the practicality of the device.

[0004] However, the aforementioned device requires manual rotation of the handles by workers when rotating the baffle and the curved plate. Since the baffle is located in the soil, and the curved plate compresses the soil during rotation, considerable effort is required. Furthermore, once the grouting body is inserted into the soft soil, workers cannot determine the location of the baffle. Therefore, a soft soil foundation reinforcement device is proposed.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1 to 4As shown, in this embodiment, a soft soil foundation reinforcement device includes a grouting body 1. A drill bit 4 is installed at the bottom of the grouting body 1. An installation plate 2 is fixedly connected to the upper part of the grouting body 1. A connecting hose 3 is installed at the upper end of the installation plate 2. The bottom of the connecting hose 3 is in communication with the interior of the grouting body 1, and the other end of the connecting hose 3 is in communication with the grout source. Two annular grooves 11 are opened on the outer wall of the grouting body 1. Multiple grout outlets 6 are opened on the side wall of the grouting body 1. The multiple grout outlets 6 are located between the two annular grooves 11 and are arranged in a straight line array from top to bottom. A first annular plate 9 and a second annular plate 10 are respectively rotatably sleeved inside the groove 11. The first annular plate 9 is located below the second annular plate 10. Two baffle plates 7 are fixedly connected between the first annular plate 9 and the second annular plate 10. Arc-shaped plates 8 are fixedly connected to the side walls of the two baffle plates 7 respectively. An extension plate 12 is fixedly sleeved on the outer wall of the second annular plate 10. A third annular plate 13 is fixedly connected to the upper end of the extension plate 12. A driving mechanism acting on the third annular plate 13 is provided on the outer wall of the grouting body 1. The driving mechanism consists of an internal gear 14, a driving gear 15, and a driving motor 16.

[0022] An internal gear 14 is fixedly connected to the inner wall of the third annular plate 13. A drive gear 15 is provided between the inner wall of the third annular plate 13 and the outer wall of the grouting body 1. The drive gear 15 meshes with the internal gear 14. A drive motor 16 is provided above the drive gear 15. The drive motor 16 is fixedly connected to the outer wall of the grouting body 1. The output shaft of the drive motor 16 is fixedly connected to the drive gear 15.

[0023] When in use, the drive motor 16 is started to drive the drive gear 15 to rotate, which in turn drives the inner gear 14 to rotate. The inner gear 14 drives the third annular plate 13 to rotate, which in turn drives the extension plate 12 and the second annular plate 10 to rotate synchronously, thereby driving the baffle plate 7 to rotate.

[0024] The outer wall of the grouting body 1 is provided with a marking point 17, which is located above the grout outlet 6. The outer wall of the third annular plate 13 is provided with two circular marks 18 and two triangular marks 19, which are arranged in a circular array and are staggered. The two triangular marks 19 are located above the two shielding plates 7.

[0025] With this setup, staff can determine whether the slurry outlet 6 is blocked based on the positions of the circular marker 18 and the triangular marker 19. When the triangular marker 19 is below the marker point 17, it indicates that the shielding plate 7 covers the slurry outlet 6. When the circular marker 18 is below the marker point 17, it indicates that the slurry outlet 6 is exposed.

[0026] The upper end of the drill bit 4 is fixedly connected to an external threaded sleeve, and the drill bit 4 is threadedly connected to the bottom of the grouting body 1 through the external threaded sleeve.

[0027] This design allows the drill bit 4 to be disassembled, making it convenient for workers to clean the inside of the grouting body 1.

[0028] Among them, pressure plates 5 are fixedly connected to both sides of the outer wall of the grouting body 1.

[0029] The pressure plate 5 allows staff to easily pick up or press the device.

[0030] This utility model provides a soft soil foundation reinforcement device, the specific working principle of which is as follows:

[0031] Before use, cover the outside of the grout outlet 6 with the baffle plate 7, then insert the grouting body 1 into the soft soil, then rotate the baffle plate 7 and drive the arc plate 8 to push away the soft soil around the grout outlet 6, thereby preventing the grout outlet 6 from coming into contact with the soil and becoming blocked. After grouting is completed, rotate the baffle plate 7 again to cover the grout outlet 6, and finally pull out the grouting body 1.

[0032] During the rotation of the shield 7, the drive mechanism can be used to operate, which can save more physical effort. Specifically, the drive motor 16 is started to drive the drive gear 15 to rotate, which in turn drives the inner gear 14 to rotate. The inner gear 14 will drive the third annular plate 13 to rotate, which in turn drives the extension plate 12 and the second annular plate 10 to rotate synchronously, thereby driving the shield 7 to rotate.

[0033] After the grouting body 1 is inserted into the soft soil, the staff can determine whether the grout outlet 6 is covered by the position of the circular mark 18 and the triangular mark 19. When the triangular mark 19 is below the mark point 17, it means that the shielding plate 7 covers the grout outlet 6. When the circular mark 18 is below the mark point 17, it means that the grout outlet 6 is exposed.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
