[0039] Embodiment 1: This embodiment provides a grouting sleeve fullness monitor. Please also refer to Figures 1 to 4, including a first grouting member 100 and a second grouting member 200 that is detachably connected; the first grouting member 100 has a laterally arranged discharge port 110 and a longitudinally arranged feed port 120. The feed port 120 is higher than the discharge port 110 in the assembled state, and the discharge port 110 is connected to the slurry discharge port 320 of the grouting sleeve 300.

[0040] The second grouting member 200 is connected to the feed port 120 and is located above the first grouting member 100. An active pressure device is provided inside the second grouting member 200 to drive the slurry to flow back.

[0041] Specifically, please refer to Figure 1. The fullness monitor provided in this embodiment, since it is provided with both a first grouting member 100 and a second grouting member 200, and the second grouting member 200 is located above the first grouting member 100, and an active pressure device is provided inside the second grouting member 200, it is possible to artificially increase the grouting volume, improve the grouting effect, and save operation time.

[0042] In an alternative embodiment of this example, preferably,

[0043] The first grouting member 100 and the second grouting member 200 are threadedly connected. For example, the first grouting member 100 may be provided with an external thread 130, and the second grouting member 200 may be provided with an internal thread 210. Or, conversely, the first grouting member 100 may be provided with an internal thread 210, and the second grouting member 200 may be provided with an external thread 130. Of course, as a deformation of the above structural form, for example, the first grouting member 100 and the second grouting member 200 may also be plugged. For example, the first grouting member 100 is plugged into the second grouting member 200, or the second grouting member 200 is plugged into the first grouting member 100. Another example is that the first grouting member 100 and the second grouting member 200 may also be connected by a clamp, and the first grouting member 100 and the second grouting member 200 are aligned and connected together with a clamp.

[0044] The above connection methods such as threaded connection, plug connection, and clamp connection are relatively simple to operate and do not require complex tools, so they can achieve the effect of quick disassembly and assembly, saving labor consumption.

[0045] In an alternative embodiment of this example, preferably,

[0046] The upper part of the first grouting member 100 is provided with an external thread 130, and the lower part of the second grouting member 200 is provided with an internal thread 210. For details, please refer to FIGS. 3 and 4. In this way, the detachable connection between the first grouting member 300 and the second grouting member 400 can be realized.

[0047] In an alternative embodiment of the present embodiment, preferably,

[0048] A material channel 220 is further provided in the second grouting member 200. The material channel 220 extends downward from above the internal thread 210 to below the internal thread 210. Of course, as a deformation of the above structure, the material channel 220 can also be provided in the first grouting member 100, and the material channel 220 extends from below the external thread 130 of the first grouting member 100

[0049] to above the external thread 130. The lower part of the material channel 220 is set in the shape of a flared opening 230 that opens downward; the upper part of the material channel 220 is set in the shape of a flared opening 230 that opens upward. By providing the material channel 220, during the grouting process, the slurry can be guided to flow in the material channel 220, avoiding the slurry from contaminating the thread area and facilitating disassembly and assembly after grouting.

[0050] In an alternative embodiment of the present embodiment, preferably,

[0051] The active pressure device includes a spring 240, a piston 250, and a piston rod 260;

[0052] The piston rod 260 is connected above the piston 250. The spring 240 is sleeved on the piston rod 260 and is located between the top end of the second grouting member 200 and the piston 250. The spring 240 always has a tendency to drive the piston 250 to move downward. For details, please refer to FIG. 1. Regarding the above-mentioned spring 250, specifically, it is a compression spring. Originally, during the grouting process, the liquid level difference between the grouting device and the grouting sleeve 300 can play a certain liquid supplement effect. However, during the grouting process of the present embodiment, the elastic restoring force is released to cause the slurry entering the second grouting member 200 to backfill, playing the role of automatic liquid supplement and providing certain assistance for the artificial use of the grouting sleeve fullness detector.

[0053] In an alternative embodiment of the present embodiment, preferably,

[0054] A limiting boss 270 is provided inside the second grouting member 200. The limiting boss 270 protrudes inward from the inner wall of the second grouting member 200 to form a boss structure.

[0055] In an alternative embodiment of the present embodiment, preferably,

[0056] The outer surface of the second grouting member 200 is provided with a scale 280.

[0057] Specifically, please refer to FIGS. 2 and 4. The boss structure can protect the piston 250 from exceeding the maximum stroke. The scale 280 provided on the outer surface of the second grouting member 200 facilitates manual adjustment of the amount of slurry perfusion according to the grouting effect.

[0058] The specific operation process of the grouting sleeve fullness monitor provided in this embodiment is as follows:

[0059] During grouting, the steel bar 400 is placed in the grouting sleeve 300, the slurry enters from the grouting port 310 and discharges from the slurry discharge port 320. The slurry passes through the first grouting member 100 and enters the second grouting member 200. At this time, the spring 240 will provide a downward pressure to push the slurry back into the grouting sleeve 300.

[0060] After a period of time, the slurry is initially coagulated, and the liquid level of the slurry in the grouting sleeve 300 drops. At this time, the piston rod 260 can be used to manually push the slurry in the first grouting member 100 and the second grouting member 200 into the grouting sleeve 300.

[0061] After grouting is completed, the second grouting member 200 can be removed and recycled by threading with the first grouting member 100.

[0062] The technical effects that can be achieved by this solution are as follows:

[0063] 1. By setting an active pressurizing device, the grouting amount can be artificially increased, the grouting effect can be improved, and the operation time can be saved.

[0064] 2. A compression spring is arranged in the active pressurizing device. By releasing the elastic restoring force of the compression spring, the effect of automatic liquid replenishment is improved.

[0065] 3. By providing an external thread 130 on the upper part of the first grouting member 100 and an internal thread 210 on the lower part of the second grouting member 200, the equipment can be disassembled and recycled; and a material channel 220 from above the external thread 130 to below the external thread 130 is arranged in the second grouting member 200, which can effectively guide the slurry to enter and avoid polluting the threaded area, further facilitating disassembly.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
