Technical Field

[0001] This utility model belongs to the field of sampling equipment technology, and more specifically, it relates to a grouting material sampling device. Background Technology

[0002] In modern construction, bridge, water conservancy, and municipal engineering, grouting materials, as special building materials with high strength, high fluidity, and micro-expansion properties, are widely used in key aspects such as structural reinforcement, gap filling, and equipment installation and fixing. Their performance directly affects the structural safety, stability, and durability of the project. For example, in the connection of precast components, the strength and density of the grouting material determine the integrity of the component splicing; therefore, testing the strength of the grouting material is particularly important.

[0003] In existing technologies, when testing the strength of grouting materials, samples are taken using a sampling tube made of plastic. When it is necessary to remove the sample for strength testing, it can be removed by tearing or cutting. However, this method of sample removal is cumbersome and the sampling device cannot be reused.

The first positioning hole is located at the snap-fit ​​joint of the first half-tube; the second positioning hole is located at the joint of the second half-tube, and the second positioning hole is aligned with the first positioning hole; one end of the connecting bolt is threaded to the first positioning hole, and the other end is connected to the second positioning hole, for fixing the first half-tube and the second half-tube.

[0009] In one possible implementation, in conjunction with the above technical solutions, the sealing structure further includes a first connecting ring, a second connecting ring, and a connecting sleeve. The first connecting ring is disposed on the first half-pipe; the second connecting ring is disposed on the second half-pipe and is hinged to the first connecting ring; the connecting sleeve is used to seal the first half-pipe and the second half-pipe by connecting the first connecting ring and the second connecting ring.

[0010] In one possible implementation, based on the above technical solutions, a sealing groove is provided at the joint of the first half-tube, and a sealing element that mates with the sealing groove is provided at the joint of the second half-tube to seal the interlocking joint.

[0034] The grout sampling device provided by this utility model will now be described.

[0035] like Figures 1 to 5 As shown, the first embodiment of this utility model provides a grout sampling device. The receiving pipe 10 is used to connect to the container supplying grout, and one end of the connecting pipe 40 is connected to the receiving pipe 10. The lower end of the sampling pipe 20 is detachably connected to the other end of the connecting pipe 40. The top cap 30 is connected to the upper end of the sampling pipe 20 and is provided with an exhaust hole. The sampling pipe 20 includes a first half-pipe 21 and a second half-pipe 22. The first half-pipe 21 and the second half-pipe 22 can be snapped together to form a tubular structure under the constraint of the top cap 30 and the connecting pipe 40 to contain the grout and form a sample.

[0036] Specifically, during the grout sampling process, the receiving pipe 10 is first connected to the container holding the grout. The grout flows through the receiving pipe 10 and the connecting pipe 40, and is finally stored in the sampling pipe 20. A cap 30 is provided at the upper end of the sampling pipe 20 to prevent grout from overflowing. The sampling pipe 20 includes a first half-pipe 21 and a second half-pipe 22. When it is necessary to store the sample, the first half-pipe 21 and the second half-pipe 22 are fastened together to form a tubular structure. When it is necessary to remove the sample, the fastened first half-pipe 21 and the second half-pipe 22 are opened to remove the sample. In some embodiments, multiple sampling pipes 20 can be provided, and the sampling pipes 20 are arranged sequentially on the connecting pipe 40. The orientation of the multiple sampling pipes 20 can be the same or different. By setting sampling pipes 20 with different orientations, it can be ensured that at least one sampling pipe 20 is facing upwards during sampling, which makes sampling more convenient. Furthermore, in this embodiment of the application, the container for holding the grouting material is a grouting sleeve, and an upper branch pipe and a lower branch pipe are provided on one side of the through pipe. The receiving pipe 10 can be connected to the upper branch pipe for sampling.

[0037] Compared with the prior art, the grout sampling device provided in this embodiment has a receiving pipe 10, a connecting pipe 40, a sampling pipe 20, and a top cap 30. The receiving pipe 10 is connected to the container for supplying grout. One end of the connecting pipe 40 is connected to the receiving pipe 10. The lower end of the sampling pipe 20 is detachably connected to the other end of the connecting pipe 40. The sampling pipe 20 includes a first half-pipe 21 and a second half-pipe 22. The first half-pipe 21 and the second half-pipe 22 can be snapped together into a tubular structure under the constraint of the top cap 30 and the connecting pipe 40 to contain the grout and form a sample. After the grout is collected, the first half-pipe 21 and the second half-pipe 22 are first separated from the connecting pipe 40, and then the first half-pipe 21 and the second half-pipe 22 are disassembled to take out the core sample. The core sample can be completely taken out by simply disassembling the connection, which effectively simplifies the sample taking process.

[0038] like Figures 1 to 5 As shown, based on the first embodiment, the present invention provides another specific embodiment as follows:

[0039] like Figure 5 As shown, both the first half-pipe 21 and the second half-pipe 22 are semi-circular pipes. The joint between the first half-pipe 21 and the second half-pipe 22 is equipped with a sealing structure to prevent grout leakage. It can be understood that the grout has a certain fluidity, and the arc-shaped inner wall of the semi-circular pipe can naturally conform to the flow trajectory of the grout, reducing the grout retention caused by right angles during the sampling process. The sealing structure can enhance the tightness between the first half-pipe 21 and the second half-pipe 22 and prevent grout leakage.

[0040] like Figures 1 to 4 As shown, the sealing structure includes a receiving groove 25 and an overlapping protrusion 26. The receiving groove 25 is located at the snap-fit ​​joint of the first half-tube 21, and the overlapping protrusion 26 is located at the snap-fit ​​joint of the second half-tube 22, and conforms to the shape of the receiving groove 25. The receiving grooves 25 on both sides of the first half-tube 21 are symmetrically arranged about the central axis of the cross-section of the first half-tube 21, and the overlapping protrusions 26 on both sides of the second half-tube 22 are symmetrically arranged about the central axis of the cross-section of the second half-tube 22. Specifically, during sampling, the receiving groove 25 and the overlapping protrusion 26 can be connected by snapping to reinforce the first half-tube 21 and the second half-tube 22. The arrangement of the receiving groove 25 and the overlapping protrusion 26 also reduces the gap between the first half-tube 21 and the second half-tube 22, preventing grout leakage. When removing the sample, the first half-tube 21 and the second half-tube 22 can be bent in opposite directions.

[0041] like Figures 1 to 4As shown, the sealing structure also includes a first positioning hole 50, a second positioning hole, and a connecting bolt. The first positioning hole 50 is located at the joint of the first half-tube 21, and the second positioning hole is located at the joint of the second half-tube 22. The second positioning hole is aligned with the first positioning hole 50. One end of the connecting bolt is threaded to the first positioning hole 50, and the other end is connected to the second positioning hole to fix the first half-tube 21 and the second half-tube 22.

[0042] Specifically, at the joint between the first half-tube 21 and the second half-tube 22, multiple first positioning holes 50 and multiple second positioning holes are respectively provided on the first half-tube 21 and the second half-tube 22. The first positioning holes 50 and the second positioning holes are aligned, and internal threads are provided in the first positioning holes 50. One end of the connecting bolt is provided with an external thread to be threadedly connected to the first positioning hole 50. Then, the other end of the connecting bolt is inserted into the second positioning hole to fix the first half-tube 21 and the second half-tube 22. When removing the sample, it is only necessary to pull upward to separate the first half-tube 21 and the second half-tube 22, which avoids the sample being damaged and effectively improves the integrity of the sample.

[0043] like Figures 1 to 5 As shown, the sealing structure also includes a first connecting ring 70, a second connecting ring 60, and a connecting sleeve. The first connecting ring 70 is disposed on the first half-tube 21, and the second connecting ring 60 is disposed on the second half-tube 22. The second connecting ring 60 is hinged to the first connecting ring 70. The connecting sleeve is used to seal the first half-tube 21 and the second half-tube 22 by connecting the first connecting ring 70 and the second connecting ring 60.

[0044] Specifically, both the first connecting ring 70 and the second connecting ring 60 are semi-circular ring structures. The inner diameter formed by the connection of the first connecting ring 70 and the second connecting ring 60 is the same as the outer diameter of the sampling tube 20. The first connecting ring 70 and the second connecting ring 60 are hinged together. By fastening the first connecting ring 70 and the second connecting ring 60, the first half-tube 21 and the second half-tube 22 can form a tubular structure. Furthermore, a connecting piece is provided outward at the connection point of the first connecting ring 70 and the second connecting ring 60. The connecting piece has two bolt holes. The connecting sleeve is threaded into the through hole of the connecting piece to realize the connection of the first connecting ring 70 and the second connecting ring 60. By setting the first connecting ring 70 and the second connecting ring 60, not only is the tightness of the first half-tube 21 and the second half-tube 22 and the integrity of sample retrieval enhanced, but the sample retrieval process is also further simplified.

[0045] like Figures 1 to 5 As shown, the connecting tube 40 is provided with an internal thread, and one end of the first half-tube 21 and the second half-tube 22 after being snapped together is provided with an external thread 41 that matches the internal thread for connecting the first half-tube 21, the second half-tube 22 and the connecting tube 40. When it is necessary to remove the sample, the connecting tube 40 and the sampling tube 20 can be separated by rotation.

[0046] like Figure 5 As shown, the sampling tube 20 also includes a first intercepting plate 23 and a second intercepting plate 24. The first intercepting plate 23 is disposed inside the first half-tube 21 and connected to the first half-tube 21; the second intercepting plate 24 is disposed inside the second half-tube 22 and connected to the second half-tube 22. When the first semi-circular tube 21 and the second semi-circular tube 22 are fastened together, there is a gap between the first intercepting plate 23 and the second intercepting plate 24, which allows pre-cracks to be formed between the sample and the grouting material.

[0047] Specifically, the first intercepting plate 23 and the second intercepting plate 24 are fixedly connected to the first half-pipe 21 and the second half-pipe 22, respectively. When the sampling tube 20 and the connecting tube 40 are separated by rotation, the gap between the first intercepting plate 23 and the second intercepting plate 24 can divide the contact surface between the sample and the grout. As the rotation time increases, the gap between the sample and the grout will increase, thereby effectively improving the convenience of sample handling.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
