Description

Technical Field

[0001] This utility model relates to the field of grouting equipment technology, specifically a grouting device for reinforcing soft soil foundations with geopolymers. Background Technology

[0002] Soft soil foundation reinforcement involves injecting cement grout, chemical grout, or other liquids into the soil pores under pressure. This fills the voids and binds soil particles, forming a composite foundation that improves bearing capacity and reduces settlement. For example, in the soft soil foundation grouting equipment disclosed in Chinese patent literature (application number: CN202223228549.5), a fixed cylinder is inserted into the soft soil foundation. Grout is injected through an outlet on the grouting pipe and then through another outlet on the fixed cylinder to complete the grouting process. However, during the insertion of the fixed cylinder into the soft soil foundation, the grouting pipe is rotated to ensure that the outlet on the grouting pipe does not align with the outlet on the fixed cylinder. The alignment of the grout outlets is crucial to prevent soil from entering the grouting pipe. During grouting, the pipe must be adjusted to align the material outlet with the grout outlet to complete the grouting process, which is quite complex. Furthermore, the fixed cylinder is not visible after penetrating below ground level, making the adjustment of the grouting pipe time-consuming and labor-intensive. Additionally, since there is only one set of material outlets, the grouting pipe needs to be continuously adjusted during grouting to align each outlet with the one on the fixed cylinder. This results in low grouting efficiency for soft soil foundations, and the use of the fixed cylinder increases the material costs of the grouting device.

[0003] Therefore, we propose a grouting device for geopolymer reinforcement of soft soil foundations. Utility Model Content

[0004] The purpose of this invention is to provide a grouting device for reinforcing soft soil foundations with geopolymers, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grouting device for reinforcing soft soil foundations with geopolymers, comprising a fixing ring, a grouting pipe, a soil-breaking cone, and a feed inlet; The T-slot is provided at the top of the retaining ring; T-shaped mounting plate, the T-shaped mounting plate is fixedly connected to the side of the grouting pipe; A fixing plate is fixedly connected to the upper part of the grouting pipe, and fixing bolts are provided on the fixing plate. A reinforcing plate is fixedly installed at the bottom of the fixing ring; A through hole is provided on the grouting pipe; The slurry outlet is located at the right end of the through hole; A movable plate is disposed inside the slurry outlet. Slurry outlet hole, the slurry outlet hole is provided on the movable plate; A positioning ring is fixedly installed on the right end of the inner wall of the slurry outlet.

[0006] Preferably, the upper part of the fixing ring is provided with a threaded hole, the fixing plate is provided with a mounting hole, and the fixing bolt passes through the mounting hole and connects with the threaded hole.

[0007] Preferably, the sum of the depths of the mounting hole and the threaded hole is greater than the length of the threaded portion on the surface of the fixing bolt.

[0008] Preferably, the slurry outlet is positioned on the moving plate between the positioning ring and the through hole.

[0009] Preferably, the T-slot extends downward to the middle of the reinforcing plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the grouting pipe enters the grout through the inlet, and the grout passes through the through hole set on the grouting pipe. The grout pushes the moving plate to the right. After the moving plate moves to the right, the grout outlet set on the moving plate moves away from the inner wall on the left side of the grout outlet. The grout enters the grout outlet through the grout outlet and completes the grouting of the soft soil foundation through the grout outlet. If soil enters the grout outlet during the insertion of the grouting pipe into the ground, it pushes the moving plate to the left. After the moving plate moves to the left and contacts the inner wall on the left side of the grout outlet, the inner wall on the left side of the grout outlet will block the grout outlet, preventing soil from entering the grouting pipe. At the same time, it saves the use of equipment materials. The grouting pipe is directly inserted into the soft soil foundation for direct grouting without any equipment adjustment. This not only allows for rapid grouting of the soft soil foundation but also improves grouting efficiency. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-7 This utility model provides a technical solution: a grouting device for reinforcing soft soil foundations with geopolymers, comprising a fixing ring 1, a grouting pipe 2, a soil-breaking cone 21, an inlet 3, a T-shaped groove 4 set on the top of the fixing ring 1, a T-shaped mounting plate 5 fixedly connected to the side of the grouting pipe 2, a fixing plate 6 fixedly connected to the upper part of the grouting pipe 2, a fixing bolt 7 set on the fixing plate 6, a reinforcing plate 8 fixedly installed at the bottom of the fixing ring 1, a through hole 9 set on the grouting pipe 2, a grout outlet 10 set at the right end of the through hole 9, a moving plate 11 set inside the grout outlet 10, a grout outlet 12 set on the moving plate 11, and a positioning ring 13 fixedly installed on the right end of the inner wall of the grout outlet 10. Grouting is performed on the soft soil foundation by inserting the grouting pipe 2 into the ground. The soil-breaking cone 21 at the bottom of the grouting pipe 2 breaks the soil. When the grouting pipe 2 is inserted into the ground, the grouting pipe 2... The grout enters through the feed inlet 3 and passes through the through hole 9 on the grouting pipe 2. The grout pushes the moving plate 11 to the right. After the moving plate 11 moves to the right, the grout outlet 12 on the moving plate 11 moves away from the inner left wall of the grout outlet 10. The grout enters the grout outlet 10 through the grout outlet 12 and completes the grouting of the soft soil foundation through the grout outlet 10. If soil enters the grout outlet 10 during the insertion of the grouting pipe 2 into the ground, it pushes the moving plate 11 to the left. After the moving plate 11 moves to the left and contacts the inner left wall of the grout outlet 10, the inner left wall of the grout outlet 10 will block the grout outlet 12, preventing soil from entering the grouting pipe 2. The grouting pipe 2 is directly inserted into the soft soil foundation for direct grouting without any equipment adjustment. This not only allows for rapid grouting of the soft soil foundation and improves grouting efficiency, but also saves on equipment and materials.

[0015] Reference embodiment: The upper part of the fixing ring 1 is provided with a threaded hole 14, and the fixing plate 6 is provided with a mounting hole 16. The fixing bolt 7 passes through the mounting hole 16 and connects with the threaded hole 14. The sum of the depths of the mounting hole 16 and the threaded hole 14 is greater than the length of the threaded part on the surface of the fixing bolt 7. Tighten the fixing bolt 7. The fixing bolt 7 fixes the grouting pipe 2 by cooperating with the threaded hole 14 and through the fixing plate 6. Loosen the fixing bolt 7. The fixing bolt 7 disengages from the threaded hole 14 and the grouting pipe 2 can be quickly disassembled.

[0016] Reference embodiment: The grout outlet 12 is positioned on the moving plate 11 between the positioning ring 13 and the through hole 9. When the moving plate 11 is on the left side inside the grout outlet 10, the upper left side of the grout outlet 12 is aligned with the inner left wall of the grout outlet 10, blocking the grout outlet 12. This prevents soil from entering the grouting pipe 2 during its insertion into the ground. After the grout is introduced into the grouting pipe 2, the moving plate 11 moves to the right under the pressure of the grout. At this time, the grout enters the grout outlet 10 through the through hole 9 and is discharged through the grout outlet 12 on the moving plate 11, thus grouting and reinforcing the soft soil foundation.

[0017] Reference embodiment: The T-groove 4 extends downward to the middle of the reinforcing plate 8, the T-mounting plate 5 extends downward, the contact area between the T-mounting plate 5 and the fixing ring 1 increases, and the fixing ring 1 stably fixes the grouting pipe 2.
