Technical Field

[0001] This application relates to the technical field of concrete detection, and particularly to a device and method for detecting the anti-seepage performance of a concrete cut-off wall. Background Art

[0002] A concrete cut-off wall is a wall-shaped anti-seepage building made of concrete, and its anti-seepage performance determines the quality of the cut-off wall. The so-called anti-seepage performance refers to the ability of the materials used in a building to resist the penetration of water or other substances under pressure. Due to the particularity of the application of concrete cut-off walls, the detection of the anti-seepage performance of concrete cut-off walls is of great importance.

[0003] In related technologies, during the construction of a concrete cut-off wall, anti-seepage detection can be carried out on the concrete used for construction (generally, more than 6 concrete specimens can be precast). After the specimens are prepared, the staff wipe the moisture on the specimens dry, then use a wire brush to remove the impurities on the surface of the specimens, and then apply a layer of sealing material on the surface of the specimens. After that, the specimens are placed into the test mold, and then the test mold with the specimens is installed on a concrete impermeability tester for detection.

[0004] Regarding the above-mentioned related technical features, there are but not limited to the following defects: 1. When processing the specimens manually, when there are too many test samples to be detected, the detection efficiency of the specimens will be reduced; 2.

[0063] Further, in the embodiments of the present disclosure, it may further include a second rotating motor (not specifically marked in this application) for driving the rotation between the clamping portion 2454 and the second section 2452; the housing of the second rotating motor is installed on the second section 2452, and the carrier plate 24543 is connected to the output shaft of the second rotating motor. The second rotating motor is used to drive the carrier plate 24543 to rotate.

[0064] In some embodiments of the present disclosure, the impurity removal mechanism 4 includes an impurity removal box body 41, an impurity removal plate 42, and an impurity removal steel brush 43; the impurity removal box body 41 is installed on one side of the wiping bracket 31; the impurity removal plate 42 is detachably arranged on the impurity removal box body 41, and the impurity removal plate 42 divides the impurity removal box body 41 into an impurity treatment chamber and an impurity collection chamber; the impurity removal steel brush 43 is installed on the impurity removal plate 42 and is located in the impurity treatment chamber; the impurity removal plate 42 is provided with a blanking hole 421 for impurities to fall; wherein, the grasping mechanism 2 has an end face cleaning state; in the end face cleaning state, on the clamping assembly 24, the clamping portion 2454 on the second section 2452 of any one clamping plate 245 releases the test piece 10, and the plane where the second section 2452 of another adjacent clamping plate 245 is located is parallel to the plane where the impurity removal plate 42 is located, and the end face of the test piece 10 contacts the impurity removal steel brush 43.

[0065] It can be understood that in the embodiments of the present disclosure, in order to remove impurities from the side and end faces of the test piece 10, it is necessary to adjust the posture of the test piece 10. For example, when in the side posture, the periphery of the test piece 10 can be subjected to impurity removal treatment; when in the end face posture, the end face of the test piece 10 can be subjected to impurity removal treatment.

[0066] Specifically, when in the side posture, the first motor 243 drives the first one-way screw 241 to rotate, the first one-way screw 241 drives the clamping plate 245 arranged thereon to move, the second motor 244 drives the second one-way screw 242 to rotate, the second one-way screw 242 drives the clamping plate 245 arranged thereon to move, and the two clamping plates 245 clamp the end face of the test piece 10, and the axial direction of the test piece 10 is the same as the axial direction of the wiping roller 32, so as to facilitate the impurity removal treatment of the side of the test piece 10. When in the end face state, since it is necessary to adjust the test piece 10 to a vertical state (the axial direction of the test piece 10 is perpendicular to the axial direction of the wiping roller 32), it is necessary to avoid the clamping plate 245 on the first one-way screw 241 or the clamping plate 245 on the second one-way screw 242 so that the posture of the test piece 10 can be adjusted.

[0067] Here, taking the avoidance of the clamping plate 245 on the first one-way screw 241 as an example (of course, the clamping plate 245 on the second one-way screw 242 can also be avoided so that the two end faces of the test piece 10 can be subjected to impurity removal):

[0068] When the clamping plate 245 on the first one-way screw 241 makes way, the first one-way screw 241 can be turned on first. The rotation of the first one-way screw 241 drives the clamping plate 245 to move. The clamping plate 245 moves away from the clamping plate 245 provided on the second one-way screw 242. At this time, the space between the two clamping plates 245 becomes larger, enabling the test piece 10 to adjust its posture. When adjusting the posture, first turn on the clamping part 2454. The clamping part 2454 clamps the end face of the test piece 10 again. Then turn on the rotating part 2453. The rotating part 2453 drives the second section 2452 to move on the first section 2451. When the plane where the second section 2452 is located is parallel to the plane where the impurity removal plate 42 is located, the posture adjustment of the test piece 10 is realized, and in this way, the impurity removal of the end face of the test piece 10 can be achieved.

[0069] See Figure 1 、 Figure 7 , in some embodiments of the present disclosure, the coating mechanism 5 includes a coating frame body 51, a coating roller 52, a heating part 53 and a coating motor 54; the coating frame body 51 is installed on one side of the impurity removal box body 41 away from the drying bracket 31, and the sealing material is placed in the coating frame body 51; the coating roller 52 is rotatably connected to the coating frame body 51, and the coating roller 52 can contact the sealing material in the coating frame body 51; the heating part 53 is provided on the coating frame body 51 for heating the sealing material in the coating frame body 51; the coating motor 54 is used to drive the coating roller 52 to rotate.

[0070] It can be understood that the sealing material can be liquid paraffin. When the liquid paraffin is placed in the coating frame body 51 and the temperature is relatively low, the liquid paraffin may solidify. By turning on the heating part 53, the heating part 53 can heat the coating frame body 51 to facilitate the melting of the liquid paraffin, and then facilitate the coating of the melted liquid paraffin onto the side surface of the test piece 10 through the coating roller 52.

[0071] As an example, the heating part 53 can be a heating wire (not specifically shown in the drawings of this application). By energizing the heating wire, the heating wire generates heat, so that the liquid paraffin in the coating frame body 51 can be melted.

[0073] Similarly, as described above, when it is necessary to press the test piece 10 into the test mold 9 through the pressing mechanism 6, it is also necessary to adjust the side posture of the test piece 10 to the end face posture (since the test piece 10 is in this surface posture during pressing), which will not be specifically described here.

[0074] As an example, the second moving member 64 may include a second moving screw 641 and a second moving motor 642; the second moving screw 641 is threadedly connected to the detection bracket 1, and the axial direction of the second moving screw 641 is the same as the axial direction of the first moving screw 222; the base of the pressing cylinder 62 is threadedly connected to the second moving screw 641, and the pressing cylinder 62 is slidably connected to the detection bracket 1; the second moving motor 642 is used to drive the second moving screw 641 to rotate.

Among them, the clamping plates 761 on the same clamping screw 762 form a clamping space for the test piece 10; the clamping motor 763 is used to drive the clamping screw 762 to rotate.

[0077] In addition, the present application also discloses a method for detecting the anti-seepage performance of a concrete cut-off wall, including the following detection method:

[0078] S1: The specimen 10 is dried. Specifically, the specimen 10 can be placed between adjacent drying felt rollers 32, the drying motor 35 is turned on, the drying motor 35 drives the drying drive wheel 34 to rotate, and multiple drying drive wheels 34 rotate under the action of the drying belt 33, and multiple drying felt rollers 32 rotate to clean the moisture on the surface of the specimen 10.

Here, take the avoidance of the clamping plate 245 on the first one-way screw 241 as an example. When the clamping plate 245 on the first one-way screw 241 avoids, the first one-way screw 241 can be turned on first. The rotation of the first one-way screw 241 drives the clamping plate 245 to move. The clamping plate 245 moves away from the clamping plate 245 provided on the second one-way screw 242. At this time, the space between the two clamping plates 245 becomes larger, enabling the posture adjustment of the test piece 10. When performing the posture adjustment, first turn on the clamping part 2454. The clamping part 2454 clamps the end face of the test piece 10 again. Turn on the rotating part 2453.
