Description

Technical Field

[0001] The invention relates to the technical field of concrete anti-seepage performance detection, and in particular to a device and method for concrete anti-seepage performance detection. Background Art

[0002] Concrete is a porous body with different pore sizes. When there is a pressure difference in the surrounding medium, there will be medium migration that obeys fluid mechanics, that is, permeation. The impermeability of concrete is the basic performance of concrete and an important characteristic of concrete durability. The impermeability of concrete not only represents the ability of concrete to resist water flow, but also affects the concrete's resistance to carbonization, resistance to chloride ion penetration and other properties.

[0018] A method for testing the impermeability of concrete, using a device for testing the impermeability of concrete as described above, comprising the following steps; 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 rail, 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, and the continuous drive of the cylinder 1 makes the upper fitting arc plate contact and squeeze the lower part of the specimen; then adjust the upper hydraulic cylinder 4 to drive the upper adjustment ring to move to the upper end of the specimen, and similarly adjust the upper fitting arc plates inside the upper adjustment ring to clamp the upper part of the specimen, thereby completing the initial clamping and fixing of the specimen; after the initial clamping and fixing, adjust the hydraulic cylinder 2 to drive the hollow processing cover to move to the upper and lower end surfaces of the specimen, and when the wire brush contacts the upper and lower end surfaces of the specimen, start the drive motor 2, and the drive motor 2 drives the wire brush to grind the upper and lower end surfaces of the specimen; Step 2: After the polishing and cleaning is completed, the forward and reverse motor 1 is started to drive the test piece to rotate 90°, and the test piece rotates to the glue spraying plate. Then, the forward and reverse motors 2 inside the lower clamping ring are started to rotate 90° in the opposite direction, so that the lower support bottom plates on the lower clamping ring rotate to the lower end of the test piece and contact with it. Similarly, the forward and reverse motors 2 inside the upper adjustment ring are adjusted to rotate the lower support bottom plates of the upper adjustment ring to the upper end of the test piece and contact with it, thereby completing the upper and lower end positioning and clamping of the test piece; after the upper and lower ends are positioned and clamped, the drive motor 1 and the spray pump are started, and the drive motor 1 drives the glue spraying plate to rotate around the side of the test piece, and the spray pump delivers the sealant to the glue spraying plate to start the circular glue spraying operation; Step 3: After the test piece is sprayed with glue in an annular shape, the test mold to be operated is placed on the docking base, and the hydraulic cylinder is adjusted to drive the middle column to move toward the test mold. When the heat conductive sheet contacts the test mold, the heat conductive sheet is expanded to both sides by the extrusion force, and the connecting spring rod is passively compressed, and the contact area between the heat conductive sheet and the test mold is increased, thereby quickly realizing the heating treatment of the test mold. After the test mold is heated, the forward and reverse motor 1 is started again to drive the test piece to rotate 90°. When the test piece rotates to the top of the test mold, the forward and reverse motor 2 inside the upper adjustment ring is reversed 90° again to make the upper fit. The arc plate clamps and positions the upper part of the specimen, and adjusts the cylinder 1 on the lower clamping ring to release the clamping of the lower part of the specimen. Then adjust the hydraulic cylinder 4 to drive the upper adjusting ring to press down, thereby gradually pressing the specimen into the test mold. When the specimen is no longer pressed down, the fitting between the test mold and the specimen is completed. When the test mold is cooled, the test mold and the specimen are moved synchronously to the placement seat of the concrete impermeability tester. When the six placement seats on the concrete impermeability tester are all placed with specimens, start the concrete impermeability tester, continuously apply pressure, and observe whether there is liquid seepage above the specimen to know the concrete impermeability.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] The device for detecting the anti-seepage performance of concrete disclosed in the present invention is mainly applied to the existing devices for detecting the anti-seepage performance of concrete. When processing concrete specimens, the concrete specimens need to be clamped and carried for many times, which will require the use of multiple clamping mechanisms. Each replacement of the clamping mechanism requires a certain amount of time and labor investment, resulting in a decrease in the efficiency of the anti-seepage performance detection of concrete and an increase in labor costs. At the same time, the configuration of multiple clamping mechanisms will result in a scenario in which the equipment cost is increased.

[0036] Reference Figure 1-Figure 13 A device for testing the impermeability of concrete comprises a concrete impermeability tester 1 and a processing seat 7. The concrete impermeability tester 1 is provided with placement seats 2 at equal distances, and each placement seat 2 is docked with a test mold 3. One side of the concrete impermeability tester 1 is fixedly connected to two docking frames 9, and the processing seat 7 is fixedly connected to the top of the two docking frames 9. The top of the processing seat 7 is provided with a placement groove. The bottom of the processing seat 7 is fixedly connected to a forward and reverse motor 10, and the output shaft of the forward and reverse motor 10 is connected to a rotating adjustment column 4 through a coupling. A multifunctional clamping mechanism 11 is provided on the outer wall of the rotating adjustment column 4. The multifunctional clamping mechanism 11 comprises a lower clamping ring 1101 and an upper adjustment ring 1105, and the outer wall of the lower clamping ring 1101 is fixedly connected with a mounting ring 1102, the mounting ring 1102 is fixedly connected to the outer wall of the rotating adjustment column 4 located below, the top of the rotating adjustment column 4 is provided with a lifting slot 1106, the inner sliding connection of the lifting slide 1106 is connected with a lifting slider 1109, the upper adjusting ring 1105 is fixedly connected to one side of the lifting slider 1109, the outer wall of the rotating adjustment column 4 located above the upper adjusting ring 1105 is fixedly connected with a fixing ring 1108, the bottom of the fixing ring 1108 is fixedly connected with a hydraulic cylinder four 1107, and the output end of the hydraulic cylinder four 1107 is fixedly connected to the top of the lifting slider 1109.

[0037] In a specific application scenario, before processing the specimen, the lower end of the specimen is placed in the lower clamping ring 1101, the cylinder 1 1112 is adjusted to drive the moving slide 1104 to move on the moving rail 1103, the forward and reverse motor 2 1114 is started to drive the upper fitting arc plate 1120 to rotate to an angle parallel to the side of the specimen, and the continuous driving of the cylinder 1 1112 makes the upper fitting arc plate 1120 contact and squeeze the side of the specimen, and then the upper hydraulic cylinder 4 1107 is adjusted to drive the upper adjustment The ring 1105 moves to the upper end of the specimen, and the upper fitting arc plates 1120 inside the upper adjusting ring 1105 clamp the side of the specimen close to the upper side, thereby completing the initial clamping and fixing of the specimen. After the initial clamping and fixing, the upper and lower ends of the specimen can be polished and cleaned by the upper and lower end processing mechanisms 8. After the polishing and cleaning is completed, the forward and reverse motors 10 are started to drive the specimen to rotate 90 degrees, and the specimen rotates to the glue spraying plate 501, and then the lower clamping ring 1101 is started. The forward and reverse motor 1114 rotates in the opposite direction by 90°, so that each lower support base plate 1118 rotates to the lower end of the test piece and contacts it. Then, the forward and reverse motor 1114 inside the upper adjustment ring 1105 is adjusted to complete the positioning and clamping of the upper and lower ends of the test piece. After the upper and lower ends are positioned and clamped, the test piece can be sprayed on the side. After the side spraying is completed, the forward and reverse motor 10 is started again to drive the test piece to rotate 90°. When the test piece rotates to the top of the test mold 3, the upper adjustment ring 1105 is turned on. The forward and reverse motor 1114 inside 105 is reversed by 90° again, so that the upper fitting arc plate 1120 clamps and positions the side of the specimen, and the bottom of the specimen is released. The hydraulic cylinder 1107 is adjusted 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. The multifunctional clamping mechanism 11 and the forward and reverse motor 10 cooperate with each other to realize all preparations before the specimen detection, which is convenient and efficient.

[0038] Specifically, when the side of the specimen is clamped by the upper fitting arc plate 1120, the reinforced friction block 1113 is pushed by the extrusion airbag 1117 to contact the side of the specimen more closely, thereby improving the firmness of the clamping of the side of the specimen.

[0039] It should be noted that when the upper and lower ends of the specimen are positioned and clamped by the lower supporting base plate 1118, the shock-absorbing spring rod 1116 is compressed, and the shock-absorbing plate 1119 contacts and squeezes the upper and lower end surfaces of the specimen, which on the one hand improves the firmness of the clamping of the upper and lower end surfaces of the specimen, and on the other hand, the shock-absorbing spring rod 1116 in a compressed state weakens the vibration during the polishing and cleaning of the upper and lower end surfaces of the specimen, thereby reducing the impact of the vibration on the stability of the specimen.

[0046] A method for testing the impermeability of concrete, using a device for testing the impermeability of concrete as described above, comprising the following steps; 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 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, and the continuous drive of the cylinder 1 1112 makes the upper fitting arc plate 1120 contact and squeeze the side of the specimen, then adjust the upper hydraulic cylinder 4 1107 to drive the upper adjustment ring 1105 to move to the test piece. At the upper end of the specimen, the upper fitting arc plates 1120 inside the upper adjusting ring 1105 are used to clamp the side of the specimen close to the upper side, thereby completing the initial clamping and fixing of the specimen. After the initial clamping and fixing, the second hydraulic cylinder 806 is adjusted to drive the hollow processing cover 804 to move to the upper and lower end surfaces of the specimen. When the wire brush 809 contacts the upper and lower end surfaces of the specimen, the second driving motor 805 is started, and the second driving motor 805 drives the wire brush 809 to grind the upper and lower end surfaces of the specimen. Step 2: After polishing and cleaning, start the forward and reverse motor 10 to drive the test piece to rotate 90°, and then the test piece rotates to the glue spraying plate 501, and then start each forward and reverse motor 2 1114 inside the lower clamping ring 1101 to rotate in the opposite direction 90°, so that each lower support base plate 1118 rotates to the lower end of the test piece and contacts therewith, and then adjust the forward and reverse motor 2 1114 inside the upper adjustment ring 1105 to complete the positioning and clamping of the upper and lower ends of the test piece. After the upper and lower ends are positioned and clamped, start the drive motor 1 508 and the spray pump 504, and the drive motor 1 508 drives the glue spraying plate 501 to rotate around the side of the test piece, and the spray pump 504 delivers the sealant to the glue spraying plate 501 to start the annular glue spraying operation; Step 3: After the test piece is annularly sprayed, the test mold 3 to be operated is placed on the docking base 15, and the hydraulic cylinder 1 606 is adjusted to drive the middle column 603 to move toward the test mold 3. When the heat conductive sheet 602 contacts the test mold 3, the heat conductive sheet 602 is spread out to both sides, and the connecting spring rod 605 is passively compressed, and the contact area between the heat conductive sheet 602 and the test mold 3 is increased, thereby quickly realizing the heating treatment of the test mold 3.

When the test mold 3 is cooled, the test mold 3 and the specimen are moved synchronously to the placement seat 2 of the concrete impermeability tester 1.
