Description

A high-pressure grouting device for basements and its usage method Technical Field

[0001] This invention relates to the field of high-pressure grouting equipment technology, specifically to a high-pressure grouting equipment for basements and its usage method. Background Technology

[0002] In modern engineering construction, to achieve better reinforcement or leak sealing effects, high-pressure grouting machines typically use chemical media that rapidly solidify from liquid to solid as the grout. The reciprocating motion of a piston within the cylinder injects this grout into weak points in the foundation or cracks in the building, strengthening the foundation or sealing leaks. Grouting is the process of forcefully delivering grout to cracks in the foundation, fault fracture zones, or joints and fissures within the building itself. Grouting improves the impermeability and integrity of the grouted strata or building, enhances foundation conditions, and ensures the safe operation of the building. High-pressure grouting utilizes the high-pressure power of machinery to inject chemical grouting materials into concrete cracks. When the grout encounters moisture in the concrete cracks, it rapidly disperses, emulsifies, expands, and solidifies. This solidified elastic material fills all the cracks in the concrete, completely blocking water flow outside the concrete structure, thus achieving the purpose of stopping water leakage.

[0003] However, when using existing grouting machines, the discharge pipe of the high-pressure grouting machine is not easy to adjust in multiple directions during grouting operations, which makes the discharge position fixed and cannot meet the construction requirements.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its deficiencies, and provided a high-pressure grouting device for basements and its usage method. Summary of the Invention

[0016] As a further optimization of this technical solution, the moving component includes a first sliding bar, a rack, a gear, a pulley, and a guide bar.

The pulley is installed at the lower end of the first sliding bar, and the lower end of the pulley slides in contact with the inner wall of the mounting cavity of the first mounting plate.

[0022] S1: Add grout:

[0023] The mixed slurry is added to the first storage pump and the second storage pump respectively to obtain a device carrying the slurry;

[0024] S2: Grouting construction

[0025] The equipment containing slurry obtained in step S1 is moved to the construction area that needs grouting by forklift. The nozzle of the discharge pipe is pointed towards the construction position, and the grouting pump is started so that the slurry in the first storage pump is sprayed to the construction position through the discharge pipe.

[0026] S3: Pressure grouting:

[0027] When the slurry in the first storage pump is used up, the one-way valve between the grouting pump and the second storage pump opens, and the one-way valve between the grouting pump and the first storage pump closes. During the grouting process of the second storage pump, the slurry in the second storage pump is pressurized and pumped out by the pressurizing pump, which improves the grouting effect.

[0028] S4:

[0030] The bottom of the discharge pipe is supported by an auxiliary support mechanism;

[0031] The universal joint allows for flexible turning of the discharge pipe;

[0032] By rotating the motor forward and backward, the gear drives the rack to slide the first sliding bar, which in turn causes the slider to slide, thereby moving the position of the limiting plate and the discharge pipe on it. The discharge pipe is a flexible discharge hose with a relatively long length to allow for movement, thus adjusting the spraying position. The pulley at the bottom ensures a quiet and smooth sliding process, and the guide bar guides the first sliding bar to move.

[0033] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention changes the existing grouting equipment by adding a second storage pump to the first storage pump. The one-way valve between the grouting pump and the second storage pump is opened while the one-way valve between the grouting pump and the first storage pump is closed, allowing the grout in the second storage pump to be pumped out and then pumped out under pressure by a booster pump. Pressure is monitored by a pressure gauge, and the discharge direction of the discharge pipe can be adjusted by rotating the turntable and sleeve assembly, allowing for adjustments based on different construction locations. An auxiliary support mechanism reinforces the bottom of the discharge pipe. Stability; the universal joint allows for flexible rotation of the discharge pipe; the forward and reverse rotation of the motor drives the rack and pinion to slide the first sliding strip, which in turn causes the slider to slide, thereby moving the position of the limiting plate and the discharge pipe on it. The discharge pipe is a flexible discharge hose with a relatively long length to allow for movement and adjustment of the spraying position. The pulley at the bottom ensures a quiet and smooth sliding process, and the guide bar guides the first sliding strip to increase the stability and smoothness of the sliding process, thus improving the stability of the discharge pipe's operation and ultimately achieving a uniform and stable discharge effect.

The one-way valve between the grouting pump 19 and the second storage pump 11 is open, while the one-way valve between the grouting pump 19 and the first storage pump 5 is closed. The grout in the second storage pump 11 can be pumped out and pressurized by the pressurizing pump 14. The pressure value is monitored by the pressure gauge 12. The discharge direction of the discharge pipe 9 can be adjusted by rotating the turntable 2 and the sleeve assembly, allowing for adjustments based on different construction locations. An auxiliary support mechanism is used to support the bottom of the discharge pipe 9. The part is supported; the universal tube 38 makes the discharge pipe 9 flexible in turning; the motor 32 drives the gear 37 to drive the rack 27 to slide the first sliding bar 33, which in turn makes the slider 29 slide, thereby moving the position of the limiting plate 30 and the discharge pipe 9 on it. The discharge pipe 9 is a discharge hose with a relatively long length to achieve movement and adjust the spraying position. The pulley 28 at the bottom makes the sliding process quiet and smooth. The guide bar 25 guides the first sliding bar 33 to move, and finally achieves the effect of adjusting the discharge position of the discharge pipe 9 without moving the machine body 13.

The discharge pipe (9) is a discharge hose. The length is set to be relatively long so as to move and achieve the effect of adjusting the spraying position. The sliding process is quiet and smooth by the pulley (28) at the bottom. The first sliding strip (33) is guided by the guide strip (25).
