Description

Technical Field

[0001] The invention relates to the technical field of waterproof testing, and more specifically to a polymer grouting waterproof testing device. Background Art

[0002] The combination of mining collapse control and separation grouting filling technology is a new research direction for the prevention and control of mining collapse geological disasters. The mining cracks in the rock strata formed by mining collapse are the flow and settlement channels of the filling slurry. After the high-pressure slurry fills the mining cracks in the rock strata, it works together with the movement of the overburden rock to form a compacted bearing area to control surface subsidence.

[0003] The Chinese invention patent with publication number CN108414425A discloses a shield tunnel joint grouting repair material waterproof performance test system and method, the system includes: displacement loading control subsystem: used to place and apply downward pressure to the elastic sealing pad to be tested, including a test bench, a reaction frame arranged on the test bench and a jack arranged on the reaction frame; segment joint specimen module: carrying the elastic sealing pad to be tested, arranged on the test bench and receiving the downward pressure applied by the jack; measurement subsystem: connected to the segment joint specimen module, including a flow meter and a high-precision measuring cup, used to quantitatively detect the amount of seepage; water pressure and slurry loading control subsystem: including a water pressure gauge, a water pressure loading device and a grouting device, used to control the water pressure and grouting of loading or unloading to the segment joint specimen module. Compared with the prior art, the present invention has the advantages of real simulation, applicability to different grouting repair materials, qualitative and quantitative evaluation, and true and reliable results.

[0004] It can be seen that the current grouting detection process is usually a universal detection method, that is, filling the grouting material into the repair groove and using subsequent water injection to achieve waterproof detection.

It has fewer functions and low detection efficiency.

The polymer grouting waterproofing test device involved in the present invention is not limited to the various structures recorded in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0033] Reference Figure 1 and Figure 2The present invention provides a polymer grouting waterproof test device, including a base assembly 1, the base assembly 1 includes a lower base 101 and an upper base 102, an upper cover assembly 2 is installed on the top of the upper base 102, connecting blocks 11 are installed on both sides of the upper cover assembly 2, a pressing assembly 4 is installed inside the upper cover assembly 2, a boosting assembly 8 and a flow guide assembly 9 are installed inside the pressing assembly 4, a template assembly 3 is installed inside the upper base 102, a water-blocking rubber plate 10 is installed between the upper cover assembly 2 and the template assembly 3, and a detection groove 103 is opened inside the upper base 102. A hydraulic hole 107 is provided on the front of the measuring groove 103, a test assembly 5 is installed inside the hydraulic hole 107, a detection sliding groove 108 is provided on the side of the hydraulic hole 107, a first positioning groove 106 and a first sliding groove 105 are provided on the side of the detecting groove 103, a control assembly 6 is installed inside the first sliding groove 105, a mold changing connection block 109 is fixedly connected to the outside of the first sliding groove 105 on both sides of the interior of the upper base 102, and a connection hole block 104 is installed on the front and back of the lower base 101, and the connection hole block 104 is matched and connected with the connection rod block 204;

[0034] In this embodiment, it is necessary to specifically explain that: an information collection unit and a control unit are installed inside the base assembly 1. The control unit controls the exposed area of ​​the upper surface of the opening and closing movable plate 7 by controlling the start and stop of the first motor 601. The information collection unit collects the height information collected by the height sensor at the guide assembly 9, the width information at the opening and closing movable plate 7 and the moving distance information at the test assembly 5. The moving distance information is used to judge the pressure of the water leakage.

[0035] The main difference between this embodiment and the prior art is that in this embodiment, the support surface of the polymer grouting material is changed to realize the waterproof performance of the grouting material under the limit state and the water release performance test under different water pressures, and at the same time, a fast mold change method and a pressurization method are used, so that grouting materials of different thicknesses can still be quickly tested under the same environment, specifically in the test component 5, the opening and closing movable plate 7, and the diversion component 9;

[0036] The above structure is the main structure of this embodiment, which solves the problem that the current grouting material can only be tested on a single surface and under a single water pressure, and cannot be tested on the surface of the grouting material in multiple water pressure environments. The transmission method of the electrical signal is an existing structure, and the specific connection method of the electrical signal is not described in detail in this embodiment.

[0037] Reference Figure 4The upper cover assembly 2 includes a cover body 201, a first grouting hole 202 and a water injection hole 203 are provided on the top of the cover body 201, the front and back sides of the cover body 201 are fixedly connected with connecting rod blocks 204, the connecting rod blocks 204 play a positioning role, a plurality of boosting auxiliary holes 205 are provided on the top of the cover body 201, and a boosting assembly 8 is installed inside the boosting auxiliary hole 205. During grouting, the grouting material enters the interior of the molding groove 302 through the first grouting hole 202, the injection groove 305, and the guide groove 304 in turn, and the material is stabilized after standing.

[0038] In this embodiment, it should be specifically explained that: the first grouting hole 202 and the water injection hole 203 are respectively connected to external pipes, and the connection method is not specifically limited in this application.

[0039] Reference Figure 5-6 The control component 6 includes a first motor 601 and a threaded rod 602. A sliding control block 603 is installed on the outer side of the threaded rod 602. The rotation of the first motor 601 is controlled by the control unit. The rotation of the first motor 601 is proportional to the moving distance of the opening and closing movable plate 7, so that the test width of the grouting material changes under the control of the first motor 601.

[0040] In this embodiment, it is necessary to specifically explain that: during the detection process, as the inner rotating plate 402 rotates, the upper surface of the grouting material is in complete contact with the water flow. At this time, the first motor 601 is controlled to drive the opening and closing movable plate 7 to move to both sides through the threaded rod 602. The information collection unit transmits the signal to the control unit to control the start and stop of the control component 6 in combination with the moving distance and stagnation time of the opening and closing movable plate 7.

[0041] Reference Figure 6-7The pressure-combining assembly 4 includes a pressure-combining plate 401, an inner rotating plate 402 is installed at the bottom of the pressure-combining plate 401, the inner rotating plate 402 separates the upper and lower parts of the water injection hole 203 and forms a plane at the bottom, the inner rotating plate 402 is hingedly installed at the bottom of the pressure-combining plate 401, the pressure-combining plate 401 is provided with a constant pressure hole 403 on the side of the water injection hole 203, the other end of the constant pressure hole 403 is installed with a guide assembly 9, the guide assembly 9 includes a water inlet detection rod 901, the bottom of the water inlet detection rod 901 is fixedly connected with a spherical connecting rod 902, and the spherical connecting rod 902 is installed on the inner rotating plate 4 02, a baffle and a third spring are installed on the upper end of the water inlet detection rod 901. The third spring makes the guide component 9 have a downward movement tendency. A height sensor is installed on the upper end of the water inlet detection rod 901. After the water flows into the side chamber of the guide component 9 through the constant pressure hole 403, the guide component 9 moves upward under the action of pressure, so that the water guide pipe 903 is connected with the constant pressure hole 403, and the water flows into the bottom of the inner rotating plate 402 through the constant pressure hole 403 and the water guide hole 404. At this time, there is no water pressure difference between the upper and lower water flows of the inner rotating plate 402, and the inner rotating plate 402 can rotate normally.

[0042] In this embodiment, it should be specifically explained that the change in water pressure makes the rising height of the guide component 9 and the rotation angle of the inner rotating plate 402 positively correlated, and the combination of the control unit and the information collection unit realizes the detection of the injected water pressure and the control of the injected water flow.

[0043] Reference Figure 8 The template assembly 3 includes a template body 301, a molding groove 302 is provided in the middle of the template body 301, the bottom of the molding groove 302 is connected to the detection groove 103, opening and closing sliding grooves 309 are provided on both sides of the bottom of the molding groove 302, and the opening and closing movable plate 7 is installed inside the opening and closing sliding groove 309, and a guide groove 304 and an injection groove 305 are provided on the upper surface of the template body 301, and the two ends of the guide groove 304 are connected to the molding groove 302 and the injection groove 305. A second sliding groove 306 and a clamping groove 307 are provided at the bottom of the template body 301, and a third sliding groove 308 is provided on the side of the clamping groove 307. A sealing groove 303 is provided on the outer side of the top of the template body 301, and a water-retaining rubber plate 10 is installed inside the sealing groove 303.

[0044] In this embodiment, it is necessary to specifically explain that: when replacing the template, when the control component 6 controls the opening and closing movable plate 7 to move sideways and contact the spherical pressing head 1204, the mold changing block 1202 is disengaged from the mold changing connecting block 109, and the template component 3 can be directly taken out upwards, thereby realizing convenient disassembly of the template component 3.

[0045] Reference Fig. 9The test assembly 5 includes a water pressure detection rod 501, a detection link 502 is hinged on the side of the water pressure detection rod 501, and a detection slider 503 is hinged on the other end of the detection link 502. The detection slider 503 is installed inside the detection sliding groove 108. When there is a water leakage, the gradual increase in water pressure pushes the test assembly 5 to move outward, and the water pressure detection rod 501 causes the detection link 502 to drive the detection slider 503 to slide inside the detection sliding groove 108. Since a scale groove is opened on the side of the detection sliding groove 108, when a leakage occurs, the change of the scale groove reflects the internal leakage.

[0046] In this embodiment, it should be specifically explained that a displacement sensor is installed inside the detection sliding groove 108 , and the displacement sensor is used to collect the moving distance information of the detection slider 503 .

[0047] Reference Fig.10 The mold changing assembly 12 includes a horizontal sliding rod 1201, and the two ends of the horizontal sliding rod 1201 are fixedly connected with a mold changing block 1202 and a spherical pressing head 1204. A slot is provided on the side of the mold changing block 1202. The mold changing assembly 12 is fixedly connected to the mold changing connecting block 109 through the slot. A second spring 1203 is installed on the outer side of the horizontal sliding rod 1201. The second spring 1203 makes the horizontal sliding rod 1201 have a tendency to move toward the spherical pressing head 1204.

[0048] In this embodiment, it is necessary to specifically explain that: when the template assembly 3 needs to be replaced to perform tests of different thicknesses after the waterproof test is completed, the control unit controls the first motor 601 to rotate again, controls the opening and closing movable plate 7 to move to both sides, and as the side of the opening and closing movable plate 7 contacts the spherical pressing head 1204, the mold changing block 1202 is disengaged from the mold changing connecting block 109, and the template assembly 3 can be directly taken out upwards at this time, thereby realizing convenient disassembly of the template assembly 3.

[0049] Reference Fig.11 The boost assembly 8 includes a boost rod 801 and a fixed threaded block 802. The fixed threaded block 802 is installed inside the pressure assembly 4. The boost rod 801 is installed inside the fixed threaded block 802 through threads to achieve the connection between the upper cover assembly 2 and the pressure assembly 4. The rotation of the boost rod 801 makes the pressure assembly 4 have a tendency to move up and down. The first spring 803 is installed inside the pressure assembly 4 on the outside of the boost rod 801. The first spring 803 makes the fixed threaded block 802 and the pressure assembly 4 have a tendency to have the maximum width. When the boost rod 801 is tightened and the position of the pressure assembly 4 remains unchanged, the first spring 803 is in a compressed state.

[0050] In this embodiment, it is necessary to specifically explain that: the initial fixation of the whole is completed at this time, and the boosting assembly 8 is tightened. Since the boosting rod 801 is threadedly connected with the fixed threaded block 802, the rotation of the boosting rod 801 drives the fixed threaded block 802 to descend, and the first spring 803 applies downward pressure to the pressing assembly 4. At this time, the gap between the pressing assembly 4 and the template assembly 3 is reduced. When the pressure threshold is reached, the outer side of the molding groove 302 is sealed, and the grouting conditions are completed inside.

[0051] Working principle of the present invention:

[0052] The main problem solved by this embodiment is: utilizing the change of the supporting surface of the polymer grouting material to realize the test of the waterproof performance of the grouting material under the limit state and the water release performance under different water pressures, which solves the problem that the current grouting material can only be tested on a single surface and under a single water pressure, and the surface of the grouting material cannot be tested in multiple water pressure environments. At the same time, by utilizing a rapid mold changing method and a pressurizing method, grouting materials of different thicknesses can still be quickly tested under the same environment, solving the current problem of difficulty in replacing molds.

[0053] The specific steps are as follows:

[0054] During the installation process, the base assembly 1 is placed on the inspection platform, the opening and closing movable plate 7 is taken out from the inside of the opening and closing sliding groove 309 and the cleanliness of the upper surface of the opening and closing movable plate 7 is checked. After the inspection is correct, the opening and closing movable plates 7 on both sides are moved to the middle position to form a closed position and placed inside the base assembly 1. With the automatic clamping of the mold changing block 1202 and the mold changing connecting block 109, the template assembly 3 and the base assembly 1 are fixed. Then the water-blocking rubber plate 10 is placed inside the sealing groove 303, and then the upper cover assembly 2 and the pressing assembly 4 are placed on the base assembly 1 as a whole, and the connecting block 1202 is aligned. The connecting rod block 204 and the connecting hole block 104 are connected to the connecting clamp blocks 11 at both ends of the upper cover assembly 2. With the water-retaining rubber plate 10 located in the upper and lower grooves, the overall initial fixation is completed at this time, and then the booster assembly 8 is tightened. Since the booster rod 801 is threadedly connected to the fixed thread block 802, the rotation of the booster rod 801 drives the fixed thread block 802 to descend, and the first spring 803 applies downward pressure to the pressure-combining assembly 4. At this time, the gap between the pressure-combining assembly 4 and the template assembly 3 is reduced. When the pressure threshold is reached, the outer side of the molding groove 302 is sealed, and the grouting conditions are completed inside.

[0055] As the grouting is performed from the first grouting hole 202 to the inside, the grouting material sequentially passes through the first grouting hole 202, the injection groove 305, and the guide groove 304 into the inside of the molding groove 302, and the material is stabilized after being left to stand.

[0056] During the waterproof water injection process, water is injected into the device through the water injection hole 203. At this time, due to the water blocking effect of the inner rotating plate 402, the water flow cannot directly contact the grouting material. However, as the water pressure gradually increases, the water flows through the constant pressure hole 403 into the side chamber of the guide component 9. The guide component 9 moves upward under the environment of gradually increasing pressure, so that the water guide pipe 903 is connected with the constant pressure hole 403, and the water flows through the constant pressure hole 403 and the water guide hole 404 to the bottom of the inner rotating plate 402. At this time, there is no water pressure difference between the upper and lower water flows of the inner rotating plate 402, and the inner rotating plate 402 can rotate normally. Since the rising height of the guide component 9 is related to the rotation angle of the inner rotating plate 402 and a height sensor is installed on the top of the water inlet detection rod 901, the change of the injected water pressure makes the rising height of the guide component 9 and the rotation angle of the inner rotating plate 402 positively correlated, so as to realize the detection of the injected water pressure and the control of the injected water flow;

[0057] During the detection process, as the inner rotating plate 402 rotates, the upper surface of the grouting material is completely in contact with the water flow. At this time, the first motor 601 is controlled to drive the opening and closing movable plate 7 to move to both sides through the threaded rod 602. The movement distance is controlled by the control unit. When the first distance is reached, there is an exposed surface with a small distance width at the bottom of the grouting material inside the upper surface forming groove 302 of the opening and closing movable plate 7. As time goes by, combined with the change in the pressure value at the test component 5, the waterproof test of the first width under the first injection water pressure is completed. The above process is repeated, and the change in the injection water pressure is controlled to achieve the limit detection of multiple water pressures and widths.

[0058] When water leakage occurs, water on the upper surface of the grouting material flows into the detection groove 103 at the bottom through the opening and closing movable plate 7. As the water pressure gradually increases, the test assembly 5 is pushed to move outward. The movement of the test assembly 5 causes the detection connecting rod 502 to drive the detection slide block 503 to slide inside the detection slide groove 108. Since a scale groove is provided on the side of the detection slide groove 108, when leakage occurs, the change of the scale groove reflects the internal leakage.

[0059] After completing the waterproof test, when the template assembly 3 needs to be replaced to perform tests of different thicknesses, the first motor 601 is controlled to rotate again, and the opening and closing movable plate 7 is controlled to move to both sides. As the side of the opening and closing movable plate 7 contacts the spherical pressing head 1204, the mold changing block 1202 is disengaged from the mold changing connecting block 109.
