Abstract
Description
Technical Field
[0001] This invention relates to the field of building materials technology, and more specifically, to a device and method for detecting the fullness of grouting material. Background Technology
[0002] Grouting is the process of filling a predetermined space or designated area with certain solidification materials, such as cement, lime, or other chemical materials. Grout fullness refers to the degree to which the grout fills a specific space or area. Only grout that meets the set standard fullness can ensure the integrity and stability of the construction structure. Therefore, the fullness of the grout is usually tested after the grout filling is completed.
[0003] In existing outdoor rapid construction projects, after grouting, pressure testing devices can be inserted deep into the grout to detect the pressure and its changing trend, thereby judging the filling degree and compactness of the grout. Combined with the detection of grout flowability, if the compactness is high, the pressure distribution is uniform, and the flowability is good, it can reflect the overall fullness of the grout. This provides important auxiliary parameters for the fullness detection of grout during grouting construction. Existing pressure testing devices generally use inductive pressure detection probes. However, during the insertion process, friction with aggregates in the grout and accidental collisions with reinforcing bars in the grouting area can accelerate the wear of the testing device and cause accidental damage, affecting the accuracy of the detection.
[0004] How to invent a device and method for detecting the fullness of grouting material to improve these problems has become an urgent issue for those skilled in the art. Summary of the Invention

[0007] Preferably, the hydraulic chamber has multiple sets of openings at the end away from the connecting rod, and a spring assembly is provided between the piston block and the hydraulic chamber.
[0008] Preferably, the sampling mechanism includes a clamping arm disposed on the side wall of the linkage rod, and multiple sets of clamping arms are distributed in a ring. The end of the clamping arm away from the linkage rod is connected to a jaw by a spring. A piston ring is clamped between the jaws. The surface of the piston ring is provided with a groove that matches the clamping arm. Multiple sets of sampling holes are opened in the upper half of the side wall of the piston ring. A discharge valve is also provided on the side wall of the piston ring.
[0009] Preferably, the connecting rod extends into the threaded block and is rotatably connected to the threaded block via a bearing, and the threaded block and the detection rod are threadedly connected.
[0010] Preferably, the rotational speed detection mechanism includes a rotating ring slidably connected to a detection rod. The rotating ring is positioned close to the end of the detection rod, and the rotating ring and the detection rod are connected by a keyway for a limiting sliding connection. A sleeve is rotatably connected to the bottom of the rotating ring, and blades are designed on the outer wall of the sleeve. A slider 1 extending into the sleeve is slidably connected to the bottom of the detection rod for limiting. The slider 1 is rotatably connected to the sleeve. A gear ring is provided on the inner side of the sleeve. A gear 1 meshing with the gear ring is provided at the bottom of the slider 1. A gear 4 is provided on the shaft of the gear 1. Gears 2 and 3 are also provided at the bottom of the slider 1. A detection disk is provided on the shaft of the gear 2. Gear 3 is designed to cooperate with gears 2 and 4.

[0011] Preferably, the number of teeth of gear four and gear two is less than the number of teeth of gear one.
[0012] Preferably, the diffusion assembly includes a connecting rod connected to the outer wall of the rotating ring, a stop block rotatably connected between the sampling area and the detection area, a torsion spring provided between the rotating shaft of the stop block and the detection rod, an annular groove matching the stop block being opened on the outer wall of the detection rod, a slip ring being slidably connected to the annular groove, and the slip ring being fixedly connected to the connecting rod.
[0013] Preferably, the top of the stop block is chamfered, and the side of the stop block away from the detection rod is provided with a groove that cooperates with the slip ring. Multiple sets of stop blocks are distributed in a ring along the axis of the detection rod.
[0014] Preferably, the blade has an obtuse triangular cross-section, with two inclined planes on the upward side and only one inclined plane on the downward side.
[0015] In summary, the beneficial effects of this invention are: 1. When testing slurry parameters, the baffles can keep the hydraulic chamber closed and protected before reaching the designated testing area, reducing friction with the aggregate in the slurry and extending service life. Moreover, the pressure testing mechanism has a simple structure. During testing, the resolution and accuracy of pressure testing are improved by refining the testing units, and the test results are converged and amplified to improve the overall accuracy of testing. Furthermore, before slurry testing, the blades detect the flowability of the slurry. During the process of entering the slurry, the slurry can be stirred and mixed, improving the dynamic mixing effect of the slurry, reducing the abnormal influence of the boundary layer, and improving the accuracy of hydraulic chamber testing.
[0016] 2. When this device performs pressure testing by moving the linkage rod downward, it can simultaneously push the piston ring downward through the clamping arm, drawing in external slurry through the sampling hole. This allows for simultaneous sampling of slurry at different depths within the testing area, greatly improving sampling efficiency and comprehensively and accurately reflecting the characteristics and uniformity of the slurry across the entire depth range. Furthermore, it avoids cross-contamination caused by multiple samplings, effectively improving the accuracy and efficiency of sampling during the slurry fullness testing process.
[0017] 3. When the test rod is pulled out after the test, the triangular cross-section design of the blades can disperse the stress between the fluids to the two sets of inclined surfaces at the top through the acute angle of the blade tip. This reduces the rotational driving force on the blades and the resistance to the test rod detaching from the slurry. At the same time, the downward movement of the sleeve causes the slip ring to move down, releasing the restriction on the stop block. This allows the stop block to rotate and extend under the action of the torsion spring, increasing the dynamics of the slurry in contact with the test rod. This reduces the friction and stress between the slurry and the test rod, and reduces the frequency of the boundary layer formed between the side wall of the test rod and the slurry. This not only reduces the resistance to the test rod detaching from the slurry, but also reduces the adhesion and slurry residue on the test rod. Attached Figure Description

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0034] Reference Figure 1-13This invention provides a method for detecting the fullness of grouting material. The detection device used in the detection method includes a detection rod 100. The top of the detection rod 100 is provided with a threaded block 101 and a display screen 102. The outer wall of the upper half of the detection rod 100 is provided with scale lines. The lower half of the detection rod 100 is alternately provided with a sampling area 300 and a detection area 400. A connecting rod 103 is slidably connected to the center of the detection rod 100. A pressure detection mechanism is provided inside the detection area 400. The pressure detection mechanism includes an annular slider 401 rotatably connected to the inner side of the detection area 400. Multiple hydraulic chambers 403 are provided inside the detection area 400. One end of each hydraulic chamber 403 away from the connecting rod 103 has an opening, and a piston block 404 is fitted inside the opening. A detection groove 410 matching the piston block 404 is formed on the side wall of the detection area 400. A baffle 402 corresponding to the detection groove 410 is provided at the bottom of the annular slider 401. A spiral groove 104 is formed on the outer side wall of the connecting rod 103. A ball bearing 407 matching the spiral groove 104 is provided on the inner side wall of the annular slider 401. A connecting ring 405 and a detection ring are provided at the center of the detection area 400. Ring 406, connecting ring 405 is connected to hydraulic chamber 403, detection ring 406 is connected to connecting ring 405, detection switch 409 is connected to the inner side of detection ring 406 by spring, and piston slider 408 designed to match detection switch 409 is slidably connected to the inner side of detection ring 406. Hydraulic chamber 403, connecting ring 405 and detection ring 406 are filled with hydraulic oil. Specifically, the area between piston slider 408 and piston block 404 in the hydraulic chamber 403, connecting ring 405 and detection ring 406 is filled with hydraulic oil for transmission. Sampling area 300 is provided with sampling mechanism, and detection rod 100 is provided with speed detection mechanism. The detection method includes the following steps: S1: Select the testing area and insert the testing rod 100 into the slurry at a uniform speed: S2: Rotate the threaded block 101 to expose the hydraulic chamber 403 to detect the pressure of the slurry at various depths and simultaneously sample the slurry at different depths; S3: Pull the detection rod 100 upwards at a uniform speed to remove the slurry; S4: Take out the sample from the 300mm internal sampling area and send it for testing to complete the rapid test of slurry fullness.
[0035] It should be noted that the display screen 102 is electrically connected to the detection switch 409 and the tactile switch 211, and can detect the pressure index of each layer at different depths and the rotation speed of the sleeve 200 when it enters the slurry.
[0036] Reference Figure 5 The hydraulic chamber 403 has multiple openings at the end away from the connecting rod 103, and a spring assembly is provided between the piston block 404 and the hydraulic chamber 403.
[0037] Reference Figure 3-4 The sampling mechanism includes clamping arms 302 disposed on the side wall of the linkage rod 103. Multiple sets of clamping arms 302 are distributed in a ring. The end of the clamping arm 302 away from the linkage rod 103 is connected to a jaw 305 by a spring. The jaws 305 clamp a piston ring 301. The surface of the piston ring 301 is provided with grooves that match the clamping arms 302. Multiple sets of sampling holes 303 are opened in the upper half of the side wall of the piston ring 301. The side wall of the piston ring 301 is also provided with a discharge valve 304. In the initial state, the piston ring 301 is in contact with the top of the inner side of the sampling area 300 to prevent air from entering.
[0038] It should be noted that the connecting rod 103 extends into the threaded block 101 and is rotatably connected to the threaded block 101 via a bearing. The threaded block 101 is threadedly connected to the detection rod 100. The side wall of the connecting rod 103 is designed with a set of prisms that are slidably connected to the detection rod 100 to ensure a slidable connection with the detection rod 100 and to prevent relative rotation between the connecting rod 103 and the detection rod 100.
[0039] Reference Figure 8-10 The rotational speed detection mechanism includes a rotating ring 202 slidably connected to a detection rod 100. The rotating ring 202 is positioned close to the end of the detection rod 100. The rotating ring 202 and the outer wall of the detection rod 100 are slidably connected along the axis of the detection rod 100 via a keyway. A sleeve 200 is rotatably connected to the bottom of the rotating ring 202. The outer wall of the sleeve 200 is designed with blades 201. A slider 204 extending into the sleeve 200 is slidably connected to the bottom of the detection rod 100. The slider 204 is rotatably connected to the sleeve 200. A toothed ring 205 is provided on the inner side of the sleeve 200. The bottom of the 4 is provided with a gear 206 that meshes with the gear ring 205. The shaft of the gear 206 is provided with a gear 212. The bottom of the slider 204 is also provided with a gear 207 and a gear 3 208. The shaft of the gear 207 is provided with a detection disk 209. The gear 3 208 is designed to cooperate with the gear 207 and the gear 4 212. The internal sliding connection of the detection disk 209 is a centrifugal slider 210 and a tactile switch 211. The detection disk 209, the centrifugal slider 210, and the centrifugal slider 210 are each provided with a spring. The outer wall of the detection rod 100 is provided with a diffusion assembly that cooperates with the blade 201.
[0040] Furthermore, the number of teeth of gear 4 212 and gear 2 207 is less than the number of teeth of gear 1 206. The meshing transmission between sleeve 200 and gear 1 206 can accelerate the rotation of gear 1 206, thereby amplifying the rotational speed of sleeve 200. Furthermore, the meshing of gear 4 212 and gear 3 208 drives the detection disk 209 to rotate. The amplified rotational speed enables the detection disk 209 to detect the rotational speed of sleeve 200, thereby improving the detection accuracy.
[0041] It should be noted that the diffusion assembly includes a connecting rod 203 connected to the outer wall of the rotating ring 202, a stop 501 rotatably connected between the sampling area 300 and the detection area 400, a torsion spring between the rotating shaft of the stop 501 and the detection rod 100, and an annular groove 502 matching the stop 501 is opened on the outer wall of the detection rod 100. A slip ring 500 is slidably connected to the annular groove 502, and the slip ring 500 is fixedly connected to the connecting rod 203.
[0042] Furthermore, the top of the stop block 501 is chamfered, and the side of the stop block 501 away from the detection rod 100 is provided with a groove that cooperates with the slip ring 500. Multiple sets of stop blocks 501 are distributed in a ring along the axis of the detection rod 100.
[0043] It should be noted that the cross-section of blade 201 is an obtuse triangular design, with two inclined planes on the upward side and only one inclined plane on the downward side. When moving downward, the inclined plane at the bottom of blade 201 can generate a tangential force with the slurry to push blade 201 to rotate. When moving upward, the stress generated by the slurry on blade 201 can be partially offset by the symmetrical inclined planes on both sides, reducing the rotation of blade 201 and thus reducing drag.
[0044] The workflow of this grout fullness testing device and method is as follows: First, the measurement area is selected, ensuring that there are no reinforcing steel bars or other components in the monitoring area. Then, the entire device is inserted into the grouting area at a uniform speed using the handles on both sides of the top of the detection rod 100. As the device penetrates the grout, the triangular cross-section design of the blade 201 transforms the vertical force between the blade 201 and the grout into horizontal stress through a set of inclined surfaces at the bottom of the blade 201. This drives the blade 201 and the sleeve 200 to rotate. During the rotation of the sleeve 200, the meshing of the gear ring 205 and gear 206 accelerates the rotation of gear 206, amplifying the detection speed of the sleeve 200. This is further enhanced by the synchronization of gear 4 212. The rotation is driven by gear 207 driven by gear 3 208. The amplified rotation speed drives the detection disk 209 to rotate. When the slurry has good flowability, the slurry has excellent fluidity, which can reduce the slurry resistance and drive the blade 201 and sleeve 200 to rotate faster. When the amplified rotation speed is sufficient to drive the detection disk 209 to rotate until the centrifugal force on the centrifugal slider 210 overcomes the elastic force of the spring connected to the centrifugal slider 210, the centrifugal slider 210 is displaced and contacts the tactile switch 211, triggering the tactile switch 211. This indicates that the slurry has good flowability. Good slurry flowability can make it more evenly distributed and fill the space, providing an auxiliary reference for the slurry fullness parameter.
[0045] It should be noted that when traditional detection devices penetrate into slurry, according to fluid mechanics, friction occurs between the device and the viscous slurry, forming a boundary layer. This boundary layer, caused by friction and material accumulation, affects the internal pressure transmission of the slurry, requiring a longer time for the slurry to regain its overall homogeneity. This not only reduces detection accuracy but also decreases the efficiency of the detection process. However, during the device's penetration into the slurry, the design of the blades 201 allows for stirring and mixing of the slurry, improving the dynamic mixing effect. The rotation and irregular shape of the blades 201 make it difficult for a boundary layer to form during the device's penetration. This not only makes the slurry mixing in the measurement area more uniform, eliminating the influence of local non-uniformity, but also reduces the abnormal effects caused by the boundary layer, thus improving detection accuracy.
[0046] When the device penetrates the slurry to a specified depth according to the scale on the side wall of the detection rod 100, it detects the slurry pressure. Rotating the threaded block 101 causes the threaded block 101 to push the connecting rod 103 downwards under the action of the threaded transmission. As the connecting rod 103 moves downwards, the engagement of the spiral groove 104 and the ball bearing 407 drives the annular slider 401 to rotate. The rotation of the annular slider 401 causes the baffle 402 to disengage from the detection groove 410, allowing the piston block 404 to communicate with the outside, thus protecting the hydraulic chamber 403. Before detection, it avoids contact with the outside, reducing influence and interference. Detection is only initiated after reaching the specified position, improving efficiency. To improve detection accuracy, when external slurry pressure is transmitted to piston block 404, it pushes piston block 404 towards hydraulic chamber 403, further squeezing the hydraulic oil medium inside hydraulic chamber 403 into the connecting ring 405. By setting multiple sets of hydraulic chambers 403 and piston blocks 404, the detection unit can be refined, improving the resolution and accuracy of pressure detection. It can more meticulously capture the pressure changes at different locations inside the slurry. Furthermore, the detection pressure of each set of hydraulic chambers 403 within the same detection area 400 is converged through the connecting ring 405 to the detection ring 406, driving the piston slider 408 to move. When the compaction is good and the pressure is appropriate, sufficient slurry pressure can push the piston block 404 until the piston slider 408 moves to contact the detection switch 409 and trigger the detection switch 409. Moreover, since the pressure is greater with greater depth, the elastic coefficient of the spring connecting the piston block 404 and the hydraulic chamber 403 inside the detection zone 400 at different heights can be appropriately changed. It should be noted that good slurry flowability means that the slurry can flow and distribute relatively smoothly, which to some extent reflects the filling situation of the slurry in the relevant space, while sufficient pressure parameters indicate that the slurry distribution in the system is relatively uniform. The slurry is uniform and has reached a certain degree of fullness. Therefore, when the flowability and pressure parameters of the slurry both reach the set indicators, it can be quickly determined that the slurry filling fullness meets the set requirements, thus realizing rapid detection of slurry fullness. In this device, when the slurry pressure parameters are good and the detection switch 409 is triggered, along with the good flowability of the slurry, it can be quickly determined that the saturation of the slurry meets the requirements. It should be noted that the sampling area 300 and the detection area 400 are distributed in multiple layers, and the triggering status of the detection switch 409 in each layer can be intuitively displayed and observed on the display screen 102 through electrical connection with the display screen 102.
[0047] Furthermore, when testing the fullness of slurry, observing the thinness and consistency of slurry samples is also one of the testing parameters. In this device, when the linkage rod 103 moves down to perform pressure testing, the downward movement of the linkage rod 103 can simultaneously push the piston ring 301 down through the clamping arm 302. As the piston ring 301 moves down, the internal pressure of the sampling area 300 decreases, allowing external slurry to be drawn into the sampling area 300 through the sampling hole 303. Since multiple sets of sampling areas 300 are set at different heights, simultaneous sampling of slurry at different depths in the testing area can be achieved, greatly improving the sampling efficiency and comprehensively and accurately reflecting the characteristics and uniformity of the slurry throughout the entire depth range. Moreover, it avoids cross-contamination caused by multiple samplings, effectively improving the accuracy and efficiency of sampling in the slurry fullness testing process.
[0048] After testing and sampling are completed, during the process of pulling the device out of the slurry, when the testing rod 100 moves upward, refer to... Figure 13 The blade 201 has a triangular cross-section. When it moves downward, the slurry fluid can push the blade 201 to rotate through the inclined surface at the bottom of the blade 201. When the blade 201 moves upward, the stress between the blade 201 and the fluid is dispersed to the two sets of inclined surfaces at the top of the blade 201 through the acute angle at the top of the blade 201, reducing the driving force for the rotation of the blade 201, thereby reducing the resistance generated by the rotation of the blade 201 and thus reducing the resistance to the detection rod 100 detaching from the slurry. At the same time, due to the downward resistance on the two sets of inclined surfaces at the top of the blade 201, the sleeve 200 can be driven downward, further... The rotating ring 202 moves downward, thereby driving the connecting rod 203 to pull the slip ring 500 downward along the annular groove 502, breaking free from the restriction of the stop block 501. This allows the stop block 501 to rotate and extend under the action of the torsion spring. When the detection rod 100 rises, it can break the boundary layer formed between the side wall of the detection rod 100 and the slurry, increase the dynamics of the slurry in contact with the detection rod 100, thereby reducing the friction and stress between the slurry and the detection rod 100, reducing the resistance of the detection rod 100 to detach from the slurry, and also reducing the adhesion and slurry residue on the detection rod 100.
[0049] It should be noted that, to ensure the accuracy of the saturation test, the test samples inside the sampling area 300 can be removed and sent for testing by disassembling the discharge valve 304. The saturation of the samples can be further judged by density measuring instrument, rheometer, laser particle size analyzer, etc. If the flowability, internal pressure of the slurry and the overall quality of the sampled slurry all meet the saturation parameters, the rapid test of the saturation of the slurry is completed. If several of them do not meet the parameter standards, professional equipment will be called for further testing or the slurry will be re-prepared and grouted.
[0050] It should be noted that when the linkage rod 103 moves down, it can be driven by the clamping arm 302 to move down and draw the sample under negative pressure. After the sampling is completed, the linkage rod 103 moves up by rotating the threaded block 101 in the opposite direction. At the same time, the baffle 402 seals the detection groove 410 to ensure the purity of the sample. At this time, when the clamping arm 302 rises, the internal pressure increases due to the sample filling it. The clamping claw 305 separates from the piston ring 301 and stays at the bottom of the sampling area 300.

Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
