Technical Field

[0001] The present invention relates to the technical field of concrete impermeability performance detection, and particularly to a device and a method for detecting the impermeability performance of concrete. Background Art

[0002] Concrete is a porous body with various pore sizes. When there is a pressure difference in the surrounding medium, there will be a medium migration that obeys fluid mechanics, that is, infiltration; the impermeability of concrete is a basic property of concrete and an important feature of the durability of concrete; the impermeability of concrete not only characterizes the ability of concrete to resist the flow of water, but also affects the properties of concrete such as carbonation resistance and chloride ion penetration resistance.

[0003] When the existing concrete impermeability performance detection device processes concrete specimens, it needs to clamp and transport them multiple times, which will require the use of various clamping mechanisms. Each time the clamping mechanism is replaced, it requires a certain amount of time and a certain amount of labor input, resulting in a reduction in the detection efficiency of the concrete impermeability performance and an increase in labor costs. At the same time, the configuration of various clamping mechanisms will increase the equipment cost and reduce the use value of the detection device. Summary of the Invention

[0004] The present invention discloses a device for detecting the impermeability performance of concrete, aiming to solve the technical problem that when the existing concrete impermeability performance detection device processes concrete specimens, it needs to clamp and transport them multiple times, which will require the use of various clamping mechanisms. Each time the clamping mechanism is replaced, it requires a certain amount of time and a certain amount of labor input, resulting in a reduction in the detection efficiency of the concrete impermeability performance and an increase in labor costs. At the same time, the configuration of various clamping mechanisms will increase the equipment cost.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A device for detecting the impermeability performance of concrete, comprising a concrete impermeability tester and a processing seat. The concrete impermeability tester is equidistantly provided with placing seats, and a test mold is docked on each placing seat. One side of the concrete impermeability tester is fixedly connected with two docking frames, and the processing seat is fixedly connected to the tops of the two docking frames. A placing groove is opened at the top of the processing seat. The bottom of the processing seat is fixedly connected with a first forward and reverse motor, and the output shaft of the first forward and reverse motor is connected with a rotating adjustment column through a coupling. A multifunctional clamping mechanism is arranged on the outer side wall of the rotating adjustment column. The multifunctional clamping mechanism comprises a lower clamping ring and an upper adjustment ring. The outer side wall of the lower clamping ring is fixedly connected with an installation ring, and the installation ring is fixedly connected to the lower part of the rotating adjustment column. A lifting chute is opened at the upper part of the rotating adjustment column, and a lifting slider is slidably connected inside the lifting chute. The upper adjustment ring is fixedly connected with the lifting slider. A fixed ring is fixedly connected to the rotating adjustment column above the upper adjustment ring, and a fourth hydraulic cylinder is fixedly connected to the bottom of the fixed ring. The output end of the fourth hydraulic cylinder is fixedly connected to the top of the lifting slider.

[0007] By arranging the multifunctional clamping mechanism, when grinding and cleaning the upper and lower ends of the test piece, applying glue to the side surface, and docking with the test mold, the multifunctional clamping can be used for clamping operations. Thus, the test piece only needs to be clamped once from processing to detection, thereby improving the processing efficiency of the test piece, reducing the input of labor costs and equipment costs, and improving the progress of concrete impermeability detection.

[0008] In a preferred scheme, the opposite sides of the lower clamping ring and the upper adjustment ring are equidistantly provided with installation grooves, and a moving rail is fixedly connected inside each installation groove. A moving slide rod is slidably connected inside each moving rail. The outer side walls of the lower clamping ring and the upper adjustment ring close to each moving slide rod are fixedly connected with a frame. A first air cylinder is fixedly connected to one side of the frame facing the moving slide rod. The output end of the first air cylinder is fixedly connected to one side of the corresponding moving slide rod.

[0009] In a preferred scheme, one side of the moving slide rod is fixedly connected with a frame, and a second forward and reverse motor is fixedly connected to one side of the frame. The output shaft of the second forward and reverse motor is fixedly connected with a flipping frame through a coupling. One end of the flipping frame is connected to the inner wall of one side of the frame through a bearing. The top of the flipping frame is fixedly connected with an upper fitting arc plate. Reinforcement holes are equidistantly opened on the arc surface of the upper fitting arc plate, and an extrusion airbag is fixedly connected inside each reinforcement hole. A reinforcement friction block is fixedly connected to each extrusion airbag, and the reinforcement friction block is partially located in the reinforcement hole. The bottom of the flipping frame is fixedly connected with a lower support bottom plate. Shock-absorbing plates are connected to both sides of the lower support bottom plate through hinges. Shock-absorbing spring rods are equidistantly fixedly connected to the same side of the two shock-absorbing plates. One end of the shock-absorbing spring rod is fixedly connected to one side of the lower support bottom plate.

[0010] In a preferred embodiment, upper and lower end processing mechanisms are provided at the upper and lower ends of the rotary adjustment column of the multifunctional clamping mechanism. The upper and lower end processing mechanisms each include two collar rings, both of which are sleeved on the rotary adjustment column. The same integrated contact frame is fixedly connected to the two collar rings, and the integrated contact frame is fixedly connected to the placement groove. Fixing frames are fixedly connected to the opposite sides of the two collar rings, hydraulic cylinders II are fixedly connected to the opposite sides of the two fixing frames, lifting frames are fixedly connected to the output ends of the two hydraulic cylinders II, and hollow processing covers are fixedly connected to the opposite sides of the two lifting frames.

[0011] By providing the upper and lower end processing mechanisms, after the specimen is initially clamped, the hydraulic cylinder II is adjusted to drive the hollow processing cover to move to the upper and lower end faces of the specimen. When the wire brush contacts the upper and lower end faces of the specimen, the drive motor II is started. The drive motor II drives the wire brush to polish the upper and lower end faces of the specimen. At the same time, the hydraulic cylinder III is adjusted to drive the extrusion wire frame to reciprocate continuously, and the extrusion spring rod drives the extrusion wire frame to make continuous adjustments. Therefore, after the wire brush initially polishes and cleans, the extrusion wire frame performs deep polishing and cleaning, thereby improving the polishing and cleaning effect of the upper and lower end faces of the specimen. During the operation of the wire brush and the extrusion wire frame, the collection pump is started. The collection pump collects the polished debris and impurities through the collection holes, preventing the splashing of this part of the debris and causing pollution.

[0012] In a preferred embodiment, collection holes are formed on the inner arc surface of the hollow processing cover. A drive motor II is fixedly connected to the side of the hollow collection cover facing the lifting frame. The output shaft of the drive motor II is fixedly connected to a rotating shaft through a coupling. One end of the rotating shaft is fixedly connected to a shaft frame. A wire brush is fixedly connected to one side of the shaft frame. An adjustment rail is fixedly connected to the other side of the shaft frame. An adjustment sliding rod is slidably connected to the adjustment rail. One side of the adjustment sliding rod is connected to an extrusion wire frame through a hinge. Extrusion spring rods are fixedly connected to the side of the extrusion wire frame facing the adjustment sliding rod at equal intervals. One end of the extrusion spring rod is fixedly connected to one side of the adjustment sliding rod. A hydraulic cylinder III is fixedly connected to the side of the shaft frame close to the adjustment sliding rod. The output end of the hydraulic cylinder III is fixedly connected to the adjustment sliding rod. A collection box is fixedly connected to one side of the hollow processing cover. A collection pump is fixedly connected to the hollow processing cover near the collection box. The collection end of the collection pump is connected to the inside of the hollow processing cover through a pipeline, and the delivery end of the collection pump is connected to the inside of the collection box through a pipeline.

[0013] In a preferred embodiment, two sets of rapid heating mechanisms are provided on the processing base, and a docking base is fixedly connected to the placement groove between the two sets of rapid heating mechanisms. Docking columns are fixedly connected to the side wall of the docking base at equal intervals. An external connection block is fixedly connected to the outer side wall of the processing base close to the docking base. A cylinder II is fixedly connected to the top of the external connection block. The output end of the cylinder II is fixedly connected to a lifting plate, and the bottom end of the lifting plate is lower than the top end of the docking base.

[0014] In a preferred embodiment, the rapid heating mechanism includes a connecting frame fixedly connected to the top of the processing base. The top of the connecting frame is fixedly connected with mounting blocks at equal intervals. One side of each mounting block is fixedly connected with a first hydraulic cylinder. The output end of the first hydraulic cylinder is fixedly connected with an intermediate column. Both sides of the intermediate column are connected with heat conducting sheets through hinges. Connecting spring rods are fixedly connected at equal intervals between the two heat conducting sheets. The outer side wall of each heat conducting sheet away from the docking base is fixedly connected with a heating frame. Electric heating tubes are fixedly connected at equal intervals inside the heating frame.

[0015] By providing the rapid heating mechanism, before the specimen is docked with the test mold, the first hydraulic cylinder is adjusted to drive the intermediate column to move towards the test mold. When the heat conducting sheet contacts the test mold, the heat conducting sheet expands towards both sides, and the connecting spring rod is passively compressed, increasing the contact area between the heat conducting sheet and the test mold, so as to quickly realize the heating treatment of the test mold.

[0016] In a preferred embodiment, a sealant spraying mechanism is provided at the position between the rapid heating mechanism and the multi-functional clamping mechanism in the storage groove. The sealant spraying mechanism includes an annular placement rail fixedly connected inside the storage groove. Two connecting sliders are slidably connected inside the annular placement rail. The tops of the two connecting sliders are fixedly connected with the same driven rotating gear. A driving motor is fixedly connected to the bottom inner wall of the storage groove where the driven rotating gear is located. The output shaft of the driving motor is fixedly connected with a driving shaft through a coupling. A driving rotating gear is fixedly connected to the outer side wall of the driving shaft. The driving rotating gear meshes with the driven rotating gear.

[0017] By providing the sealant spraying mechanism, when the specimen rotates to the glue spraying plate, the driving motor and the spraying pump are started. The driving motor drives the glue spraying plate to rotate around the side of the specimen. The spraying pump transports the sealant into the glue spraying plate to start the annular glue spraying operation. Compared with manual glue rolling, this glue spraying method has a better sealant coating effect, making the connection between the specimen and the test mold tighter, and further preventing water from overflowing between the two, resulting in the failure of the concrete impermeability test.

[0018] In a preferred embodiment, a mounting rod is fixedly connected to the top of the driven rotating gear, and a glue spraying plate is fixedly connected to the top of the mounting rod. Glue spraying holes are opened at equal intervals on the arc surface of the glue spraying plate. A placement plate is fixedly connected to one side of the mounting rod. A storage box is fixedly connected to the top of the placement plate. A spraying pump is fixedly connected to the top of the storage box. The spraying end of the spraying pump is connected to the inside of the glue spraying plate through a pipeline, and the extraction end of the spraying pump is connected to the inside of the storage box through a pipeline.

[0019] A method for detecting the impermeability performance of concrete, using a device for detecting the impermeability performance of concrete as described above, includes the following steps;

[0020] Step 1: Place the lower end of the specimen in the lower clamping ring. Adjust the cylinder 1 to drive the moving slide bar to move on the moving track. Start the forward and reverse motor 2 to drive the upper fitting arc plate to rotate to an angle parallel to the side of the specimen. The continuous drive of cylinder 1 causes the upper fitting arc plate to contact and squeeze the lower part of the specimen. Then, adjust the hydraulic cylinder 4 above to drive the upper adjusting ring to move to the upper end of the specimen. Similarly, adjust each upper fitting arc plate inside the upper adjusting ring to clamp the upper part of the specimen, thus completing the preliminary clamping and fixing of the specimen. After the preliminary clamping and fixing, adjust the hydraulic cylinder 2 to drive the hollow treatment cover to move to the upper and lower end faces of the specimen. When the wire brush contacts the upper and lower end faces of the specimen, start the drive motor 2, and the drive motor 2 drives the wire brush to polish the upper and lower end faces of the specimen.

[0021] Step 2: After the polishing and cleaning are completed, start the forward and reverse motor 1 to drive the specimen to rotate by 90°. Then the specimen rotates to the glue spraying plate. Next, start each forward and reverse motor 2 inside the lower clamping ring to rotate in the reverse direction by 90°, so that each lower support base plate on the lower clamping ring rotates to the lower end of the specimen and contacts it. Similarly, adjust the forward and reverse motor 2 inside the upper adjusting ring to make each lower support base plate of the upper adjusting ring rotate to the upper end of the specimen and contact it, thus completing the positioning and clamping of the upper and lower ends of the specimen. After the positioning and clamping of the upper and lower ends, start the drive motor 1 and the spraying pump. The drive motor 1 drives the glue spraying plate to rotate around the side of the specimen, and the spraying pump transports the sealant to the glue spraying plate to start the annular glue spraying operation.

[0022] Step 3: After the annular glue spraying of the specimen is completed, place the test mold to be operated on the docking base. Adjust the hydraulic cylinder 1 to drive the middle column to move towards the test mold. When the heat conduction sheet contacts the test mold, the heat conduction sheet expands towards both sides under the extrusion force, then the connecting spring rod is compressed passively, and the contact area between the heat conduction sheet and the test mold increases, thus quickly realizing the heating treatment of the test mold. After the heating treatment of the test mold, start the forward and reverse motor 1 again to drive the specimen to rotate by 90°. When the specimen rotates above the test mold, the forward and reverse motor 2 inside the upper adjusting ring rotates in the reverse direction by 90° again, so that the upper fitting arc plate clamps and positions the upper part of the specimen. Adjust the cylinder 1 on the lower clamping ring to loosen the clamping of the lower part of the specimen, then adjust the hydraulic cylinder 4 to drive the upper adjusting ring to press down, so as to gradually press the specimen into the test mold. When the specimen can no longer be pressed down, the fitting between the test mold and the specimen is completed. When the test mold cools down, move the test mold and the specimen synchronously to the placement seat of the concrete impermeability tester. When specimens are placed on all six placement seats of the concrete impermeability tester, start the concrete impermeability tester and continuously apply pressure. By observing whether there is liquid seepage above the specimen, the concrete impermeability can be known.

[0023] As can be seen from the above, the device for detecting the impermeability of concrete provided by the present invention has the technical effect of improving the clamping operation during the grinding and cleaning of the upper and lower ends of the test piece, the gluing of the side surface, and the docking with the test mold through the multi-functional clamping, so that the test piece only needs to be clamped once from processing to detection, thereby improving the processing efficiency of the test piece, reducing the input of labor costs and equipment costs, and improving the detection progress of the concrete impermeability.

Detailed implementation manners

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0039] A device for detecting the impermeability performance of concrete disclosed by the present invention is mainly applied to the scenario where the existing device for detecting the impermeability performance of concrete requires multiple clamping and handling of concrete specimens during the treatment process. This will require the use of multiple clamping mechanisms. Each time a clamping mechanism is replaced, it will take a certain amount of time and a certain amount of labor input, resulting in a reduction in the detection efficiency of the impermeability performance of concrete and an increase in labor costs. At the same time, the configuration of multiple clamping mechanisms will result in an increase in equipment costs.

[0040] Referring to Figures 1 - 13 , a device for detecting the impermeability performance of concrete, includes a concrete impermeability tester 1 and a processing seat 7. The concrete impermeability tester 1 is equidistantly provided with placing seats 2, and a test mold 3 is docked on each placing seat 2. Two docking frames 9 are fixedly connected to one side of the concrete impermeability tester 1, and the processing seat 7 is fixedly connected to the tops of the two docking frames 9. A placing groove is opened at the top of the processing seat 7. A positive and negative rotation motor one 10 is fixedly connected to the bottom of the processing seat 7, and the output shaft of the positive and negative rotation motor one 10 is connected to a rotation adjustment column 4 through a coupling. A multi-functional clamping mechanism 11 is provided on the outer side wall of the rotation adjustment column 4. The multi-functional clamping mechanism 11 includes a lower clamping ring 1101 and an upper adjustment ring 1105. An installation ring 1102 is fixedly connected to the outer side wall of the lower clamping ring 1101, and the installation ring 1102 is fixedly connected to the outer side wall of the rotation adjustment column 4 at the lower part. A lifting chute 1106 is opened at the top of the rotation adjustment column 4, and a lifting slider 1109 is slidably connected to the inside of the lifting chute 1106. The upper adjustment ring 1105 is fixedly connected to one side of the lifting slider 1109. A fixing ring 1108 is fixedly connected to the outer side wall of the rotation adjustment column 4 above the upper adjustment ring 1105, and a hydraulic cylinder four 1107 is fixedly connected to the bottom of the fixing ring 1108. The output end of the hydraulic cylinder four 1107 is fixedly connected to the top of the lifting slider 1109.

[0041] In a specific application scenario, before processing the test piece, place the lower end of the test piece in the lower clamping ring 1101. Adjust the first cylinder 1112 to drive the moving slide rod 1104 to move on the moving rail 1103. Start the forward and reverse motor two 1114 to drive the upper fitting arc plate 1120 to rotate to an angle parallel to the side of the test piece. The continuous drive of the first cylinder 1112 causes the upper fitting arc plate 1120 to contact and squeeze the side of the test piece. Then, adjust the fourth hydraulic cylinder 1107 above to drive the upper adjusting ring 1105 to move to the upper end of the test piece, and clamp the side of the test piece near the upper part through each upper fitting arc plate 1120 inside the upper adjusting ring 1105, thereby completing the preliminary clamping and fixing of the test piece. After the preliminary clamping and fixing, the upper and lower end processing mechanism 8 can be used to polish and clean the upper and lower ends of the test piece. After the polishing and cleaning are completed, start the forward and reverse motor one 10 to drive the test piece to rotate 90°. Then the test piece rotates to the glue spraying plate 501. Next, start each forward and reverse motor two 1114 inside the lower clamping ring 1101 to rotate reversely 90°, so that each lower support bottom plate 1118 rotates to the lower end of the test piece and contacts it. Then, adjust the forward and reverse motor two 1114 inside the upper adjusting ring 1105 to complete the positioning and clamping of the upper and lower ends of the test piece. After the positioning and clamping of the upper and lower ends, the test piece can be subjected to side glue spraying operation. After the side glue spraying is completed, start the forward and reverse motor one 10 again to drive the test piece to rotate 90°. When the test piece rotates above the test mold 3, the forward and reverse motor two 1114 inside the upper adjusting ring 1105 rotates reversely 90° again, so that the upper fitting arc plate 1120 clamps and positions the side of the test piece, and the clamping of the lower part of the test piece is released. Then, adjust the fourth hydraulic cylinder 1107 to drive the upper adjusting ring 1105 to press down, so as to gradually press the test piece into the test mold 3. When the test piece is no longer pressed down, the fitting between the test mold 3 and the test piece is completed. The mutual cooperation of the multi-functional clamping mechanism 11 and the forward and reverse motor one 10 realizes all the preparations before the test piece detection, which is convenient and efficient.

[0042] Specifically, when clamping the side of the test piece through the upper fitting arc plate 1120, the reinforcement friction block 1113 contacts the side of the test piece more tightly under the push of the extrusion airbag 1117, thereby improving the firmness of the clamping of the side of the test piece.

[0043] It should be noted that when positioning and clamping the upper and lower ends of the test piece through the lower support bottom plate 1118, the shock absorption spring rod 1116 is compressed, and the shock absorption plate 1119 contacts and squeezes the upper and lower end faces of the test piece. On the one hand, it improves the firmness of the clamping of the upper and lower end faces of the test piece. On the other hand, the shock absorption spring rod 1116 in the compressed state weakens the vibration during the polishing and cleaning of the upper and lower end faces of the test piece, and reduces the influence of the vibration on the stability of the test piece.

[0044] Refer to Figures 1 - 6, in a preferred embodiment, mounting grooves are equidistantly formed on the opposite sides of the lower clamping ring 1101 and the upper adjusting ring 1105, and a moving rail 1103 is fixedly connected to the inside of each mounting groove. A moving slide bar 1104 is slidably connected to the inside of each moving rail 1103. On the outer side walls of the lower clamping ring 1101 and the upper adjusting ring 1105 close to each moving slide bar 1104, a frame 1110 is fixedly connected. On the side of the frame 1110 facing the moving slide bar 1104, a first cylinder 1112 is fixedly connected. The output end of the first cylinder 1112 is fixedly connected to one side of the corresponding moving slide bar 1104. One side of the moving slide bar 1104 is fixedly connected to a frame 1111, and on one side of the frame 1111, a forward and reverse motor two 1114 is fixedly connected. The output shaft of the forward and reverse motor two 1114 is fixedly connected to a flipping frame 1115 through a coupling. One end of the flipping frame 1115 is connected to the inner wall of one side of the frame 1111 through a bearing. On the top of the flipping frame 1115, an upper fitting arc plate 1120 is fixedly connected. Reinforcement holes are equidistantly formed on the arc surface of the upper fitting arc plate 1120, and an extrusion air bag 1117 is fixedly connected to the inside of each reinforcement hole. A reinforcement friction block 1113 is fixedly connected to each extrusion air bag 1117, and the reinforcement friction block 1113 is partially located in the reinforcement hole. On the bottom of the flipping frame 1115, a lower support bottom plate 1118 is fixedly connected. On both sides of the lower support bottom plate 1118, shock-absorbing plates 1119 are connected through hinges. On the same side of the two shock-absorbing plates 1119, shock-absorbing spring rods 1116 are equidistantly fixedly connected, and one end of the shock-absorbing spring rod 1116 is fixedly connected to one side of the lower support bottom plate 1118.

[0045] Referring to Figure 1 , Figure 7 , Figure 8 , Figure 9 and Figure 10, in a preferred embodiment, upper and lower end processing mechanisms 8 are provided at the upper and lower ends of the rotation adjustment column 4 of the multifunctional clamping mechanism 11.

[0050] A method for detecting the impermeability performance of concrete, using the device for detecting the impermeability performance of concrete as described above, includes the following steps;

[0051] Step 1: Place the lower end of the specimen in the lower clamping ring 1101. Adjust the cylinder 1 1112 to drive the moving slide rod 1104 to move on the moving rail 1103. Start the forward and reverse motor 2 1114 to drive the upper fitting arc plate 1120 to rotate to an angle parallel to the side of the specimen. The continuous drive of the cylinder 1 1112 causes the upper fitting arc plate 1120 to contact and squeeze the side of the specimen. Then, adjust the upper hydraulic cylinder 4 1107 above to drive the upper adjusting ring 1105 to move to the upper end of the specimen. Clamp the side of the specimen near the upper part through each upper fitting arc plate 1120 inside the upper adjusting ring 1105, thereby completing the preliminary clamping and fixing of the specimen. After the preliminary clamping and fixing, adjust the hydraulic cylinder 2 806 to drive the hollow processing cover 804 to move to the upper and lower end faces of the specimen. When the wire brush 809 contacts the upper and lower end faces of the specimen, start the driving motor 2 805, and the driving motor 2 805 drives the wire brush 809 to polish the upper and lower end faces of the specimen;

[0052] Step 2: After the grinding and cleaning are completed, start the forward and reverse motor 10 to drive the specimen to rotate by 90°. Then the specimen rotates to the glue spraying plate 501. Next, start the forward and reverse motors 1114 inside the lower clamping ring 1101 to rotate reversely by 90°, so that each lower support base plate 1118 rotates to the lower end of the specimen and contacts it. Then adjust the forward and reverse motors 1114 inside the upper adjusting ring 1105, thereby completing the positioning and clamping of the upper and lower ends of the specimen. After the upper and lower ends are positioned and clamped, start the driving motor 508 and the spraying pump 504. The driving motor 508 drives the glue spraying plate 501 to rotate around the side of the specimen, and the spraying pump 504 transports the sealant to the glue spraying plate 501 to start the annular glue spraying operation;

[0053] Step 3: After the annular glue spraying of the specimen is completed, place the test mold 3 to be operated on the docking base 15. Adjust the hydraulic cylinder 606 to drive the middle column 603 to move towards the test mold 3. When the heat conducting sheet 602 contacts the test mold 3, the heat conducting sheet 602 expands towards both sides, then the connecting spring rod 605 is compressed passively, and the contact area between the heat conducting sheet 602 and the test mold 3 increases, thereby quickly realizing the heat treatment of the test mold 3. After the heat treatment of the test mold 3, start the forward and reverse motor 10 again to drive the specimen to rotate by 90°. When the specimen rotates above the test mold 3, the forward and reverse motor 1114 inside the upper adjusting ring 1105 rotates reversely by 90° again, so that the upper fitting arc plate 1120 clamps and positions the side of the specimen, and the clamping at the lower part of the specimen is released. Then adjust the hydraulic cylinder 1107 to drive the upper adjusting ring 1105 to press down, thereby gradually pressing the specimen into the test mold 3. When the specimen is no longer pressed down, the fitting between the test mold 3 and the specimen is completed. When the test mold 3 cools down, move the test mold 3 and the specimen synchronously to the placement seat 2 of the concrete impermeability tester 1. When specimens are placed on all six placement seats 2 of the concrete impermeability tester 1, start the concrete impermeability tester 1 and continuously apply pressure. By observing whether there is liquid seepage above the specimen, the concrete impermeability can be known.
