Description

Technical Field

[0001] The utility model relates to the technical field of grouting, in particular to a device capable of self-cleaning and continuously monitoring grouting pressure. Background Art

[0002] Under the combined effects of long-term traffic loads and complex natural environments, highways often experience defects such as voids under the pavement slab, cracks in the semi-rigid base, localized strength deficiencies, and uneven settlement of the soft soil subgrade. Grouting is often used to address these defects in practical projects. During the grouting process, real-time monitoring of the grouting pressure is required to ensure it remains within a reasonable and safe range, ensuring both efficiency and safety. To ensure the quality of grouting projects and the rapid reopening of traffic, geopolymer or fast-setting, early-strength cement grouting materials are currently widely used.

[0003] When grouting equipment is operating, the pressure of the slurry inside the pipe is monitored by a pressure gauge installed on the grouting pipe. The pressure gauge is in direct contact with the slurry. For geopolymer and fast-setting, early-strength grouting materials, which are characterized by rapid setting and high early strength, if the slurry at the pressure gauge is not cleaned promptly during the grouting process, the slurry will solidify within a short period of time, causing the pressure gauge to be unable to read properly. This necessitates manual removal and replacement of the pressure gauge, preventing continuous grouting. Furthermore, the slurry cannot be completely cleaned, resulting in poor results. This not only interrupts the grouting process but also increases grouting costs. Summary of the Invention

[0004] To this end, the utility model provides a self-cleaning device for continuously monitoring grouting pressure to solve the problem in the prior art that during the grouting process of geopolymer or fast-setting and early-strength cement grouting materials, the grouting pressure gauge cannot be cleaned in time, resulting in the pressure gauge being easily damaged and unable to continuously monitor the slurry pressure.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A device that can self-clean and continuously monitor grouting pressure includes a first pressure gauge, a second pressure gauge, a first valve, a second valve, a water pipe, a slurry pipe, a first T-shaped tee, and a second T-shaped tee. It is characterized in that: the water pipe is located on one side of the slurry pipe and is connected to the slurry pipe through the first T-shaped tee and the second T-shaped tee. The first valve is located inside the first T-shaped tee, and the second valve is located inside the second T-shaped tee. The first pressure gauge is vertically welded to the plane where the first T-shaped tee is located and is connected to the inner side of the first valve.

[0008] Preferably, by adjusting the first valve and the second valve, the first pressure gauge and the second pressure gauge can be controlled to be connected to the slurry pipe or the water pipe, thereby measuring the slurry pipe pressure and cleaning the pressure gauge.

[0009] Preferably, the first valve and the second valve can work independently to achieve different working states of the first pressure gauge and the second pressure gauge.

[0010] Preferably, the first pressure gauge is perpendicular to the plane of the first T-shaped tee and is connected to the inner side of the first T-shaped tee through the first port of the first valve; the second pressure gauge is perpendicular to the plane of the second T-shaped tee and is connected to the inner side of the second T-shaped tee through the first port of the second valve.

[0013] Preferably, the two throttle valves can control the water flow in the water pipe.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. During the operation, the pressure gauge can be cleaned and the pressure inside the slurry pipe can be monitored by adjusting the valve. After the grouting operation is completed, the slurry inside the slurry pipe can be cleaned by adjusting the valve.

[0016] 2. When one pressure gauge is cleaning, the other pressure gauge is detecting the pressure, and vice versa, so that the slurry pressure can be continuously monitored in real time.

DETAILED DESCRIPTION

[0021] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] In the description of the present invention, it should be noted that the terms "middle", "upper", "lower", "left", "right", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0023] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.

[0024] like Figure 1 、 Figure 2As shown, the specific scheme of the embodiment is as follows: A self-cleaning device for continuously monitoring grouting pressure includes a first pressure gauge 1, a second pressure gauge 2, a first valve 3, a second valve 4, a third valve 5, a water pipe 9, a slurry pipe 10, a first T-shaped tee 11, and a second T-shaped tee 12. The water pipe 9 is located on one side of the slurry pipe 10 and is connected to the slurry pipe 10 through the first T-shaped tee 11 and the second T-shaped tee 12. The first valve 3 is located inside the first T-shaped tee 11, and the second valve 4 is located inside the second T-shaped tee 12. The third valve 5 is provided at the water inlet 6 end of the water pipe 9. The first pressure gauge 1 is vertically welded to the plane of the first T-shaped tee 11 and is connected to the inner side of the first valve 3. The second pressure gauge 2 is vertically welded to the plane of the second T-shaped tee 12 and is connected to the inner side of the second valve 4.

[0025] Specifically, the first valve 3 is a spherical valve, such as Figure 2 As shown, the first valve 3 is respectively provided with a first port 3-1, a second port 3-2 and a third port 3-3 in three directions. The opening direction of the first port 3-1 is perpendicular to the plane where the first T-shaped tee 11 is located. The opening direction of the second port 3-2 and the third port 3-3 is the same and can rotate parallel to the plane where the first T-shaped tee 11 is located; the second valve 4 has the same structure as the first valve 3.

[0026] Specifically, when the first valve 3 is opened, the second opening 3-2 and the third opening 3-3 of the ball valve face parallel to the water pipe 9, as shown in FIG. Figure 2 As shown, the first pressure gauge 1 is now connected to the water pipe 9 and isolated from the slurry pipe 10. When the first valve 3 is closed, the second and third openings 3-2 and 3-3 of the ball valve are perpendicular to the water pipe, the first pressure gauge is isolated from the water pipe and connected to the slurry pipe. The principle of the second valve 4 is the same as that of the first valve 3.

[0027] Specifically, the first pressure gauge 1 is perpendicular to the plane of the first T-shaped tee 11 and is connected to the inner side of the first T-shaped tee 11 through the first port 3-1 of the first valve 3; the second pressure gauge 2 is perpendicular to the plane of the second T-shaped tee 12 and is connected to the inner side of the second T-shaped tee 12 through the first port of the second valve 4.

[0028] Specifically, because the first pressure gauge 1 is welded to the first T-shaped tee 11 and passes through the first port 3-1 to monitor the pressure inside the pipeline, when the first valve 3 rotates, the first pressure gauge 1 does not rotate with it, but remains stationary relative to the first T-shaped tee 11. The same applies to the second pressure gauge 2.

[0029] The water pipe 9 is a T-shaped water pipe, one end of which is a water inlet 6, and the other two ends are respectively connected to a first T-shaped tee 11 and a second T-shaped tee 12; a third valve 5 is provided at the water inlet 6 end of the water pipe 9, and a first throttle valve 13 and a second throttle valve 14 are respectively provided at the first water outlet 7 and the second water outlet 8 at both ends.

[0030] Specifically, when the third valve 5 is opened, water flows into the water pipe 9 from the water inlet 6, and then is controlled by the first valve 3 or the second valve 4 to clean the first pressure gauge 1 or the second pressure gauge 2. The cleaned water is discharged through the first water outlet 7 or the second water outlet 8.

[0031] Specifically, the first water outlet 7 and the second water outlet 8 are respectively connected to a first throttle valve 13 and a second throttle valve 14 , which can control the water flow rate to achieve the purpose of water saving.

[0032] Specifically, the principles of pressure gauge self-cleaning and continuous monitoring of grouting pressure are as follows:

[0033] During the grouting process, slurry is transported from left to right through the slurry pipe 10. If both the first valve 3 and the second valve 4 are closed, and both the first pressure gauge 1 and the second pressure gauge 2 are connected to the slurry pipe 10 and isolated from the water pipe, the slurry pressure inside the slurry pipe 10 can be monitored. To clean the first pressure gauge and continue to monitor the slurry pressure, simply open the first valve 3, keep the second valve 4 closed, and then open the third valve 5. At this point, the first valve 3 is isolated from the slurry pipe 10 and connected to the water pipe 9. Water flows into the water pipe through the third valve 5. Because the first valve 3 is open and the second valve 4 is closed, the water flows through the first valve 3 and cleans the first pressure gauge, finally flowing out of the pipe through the first throttle valve 13 and the first water outlet 7. At the same time, the second pressure gauge 2 is connected to the slurry pipe 10, so the slurry pressure can continue to be read. To clean the second pressure gauge 2 and continue to monitor the slurry pressure, similarly, simply close the first valve 3, open the second valve 4, and open the third valve 5. If grouting is completed, the first pressure gauge 1 and the second pressure gauge 2 need only be cleaned by opening both the first valve 3 and the second valve 4. If the slurry pipeline needs to be cleaned, the first valve 3 and the second valve 4 need only be closed.
