In some buildings, building materials (such as plastic concrete) are required to have special properties, such as impermeability, which refers to the ability of the materials used in building materials to resist the penetration of water or other liquids (light oil, heavy oil) under pressure.

[0003] In the related art, the anti-seepage performance of building materials is often measured by an anti-seepage meter. The general measurement steps are: before measuring the building materials, the building materials need to be cast into test pieces (usually cylindrical) according to the standards, and then the sealing material (for example, paraffin or butter) is coated on the outer circumference of the test piece, and then the test piece coated with the sealing material is pressed into a test mold by a press, and finally the test mold is fixed to the anti-seepage meter by multiple bolts to test the anti-seepage performance of the building materials.

[0004] With regard to the above-mentioned related technologies, there are the following defects: the test mold is fixed to the impermeability tester by bolts. In the prior art, the number of bolts is generally set to six, and the staff is required to tighten or loosen the bolts one by one, which will lead to a decrease in the detection efficiency of building materials; at the same time, when the staff tightens the bolts, some bolts have different tightening forces, which will lead to poor sealing effect on the test piece and affect the detection accuracy of the test piece.

[0056] See also Figure 1 , Figure 2 The measuring device also includes a second rotating mechanism 7 for connecting the bracket 4 to the test mold 12; the second rotating mechanism 7 includes a rotating bracket 73, a rotating disk 72 and a second rotating motor 71; the rotating bracket 73 is installed on one side of the anti-seepage instrument body 1; as an example, the rotating bracket 73 is located on the side of the lifting bracket 51 away from the anti-seepage instrument body 1, the rotating disk 72 is rotatably connected to the rotating bracket 73, and the rotating disk 72 has a magnetic suction part 721; the test mold 12 has an empty state and an installed state; when the test mold 12 is in the empty state, the test mold 12 is arranged on the rotating disk 72 through the magnetic suction part 721; when the test mold 12 is in the installed state, the test mold 12 is threadedly connected to the bracket 4 on the lifting mechanism 5 with the cooperation of the second rotating mechanism 7.

[0059] In the second aspect, the present application discloses a method for measuring the permeability coefficient of a plastic anti-seepage wall. The method is applied to the above-mentioned measuring device. Specifically, the measuring method includes the following: S1: Place the test piece on the first bearing part 41 and the second bearing part 42, and connect the first bracket 411 and the second bracket 421 through the fixing part 44. Specifically, if only one test piece needs to be tested, place the test piece on the second tray 422 (because the second bearing part 42 has a cover part 43, it is convenient to fix the cover part 43 and the test mold 12); if multiple test pieces need to be tested, here taking the test of two test pieces as an example, one test piece can be placed on the first tray 412, the other test piece can be placed on the second tray 422, and then the second bracket 421 can be placed on the first bracket 411, and the first bracket 411 and the second bracket 421 can be fixed through the fixing part 44.

[0060] S2: placing a plurality of trial molds 12 on the rotating disk 72 .

[0061] S3: the lifting mechanism 5 delivers the bracket 4 with multiple test pieces to the top of multiple test molds 12, drives the bracket 4 to extend into the test molds 12, and starts the second rotating mechanism 7, which fixes the test molds 12 and the bracket 4.

[0062] Specifically, the rotating motor is turned on, and the rotating motor drives the rotating active gear 62 to rotate, and the rotating active gear 62 rotates to drive the rotating driven gear 63 to move, and the rotating driven gear 63 moves to drive the lifting bracket 51 to move, so that the lifting plate 54 moves to the position directly above the position where the bracket 4 is placed, and the lifting mechanism 5 and the lifting plate 54 are adjusted, and the lifting plate 54 clamps the bracket 4, and the lifting mechanism 5 and the first rotating mechanism 6 are adjusted again, and the lifting plate 54 with the bracket 4 is placed directly above the test mold 12, and the lifting mechanism 5 is adjusted, and the lifting mechanism 5 places the bracket 4 in the test mold 12, at this time, the covering part 43 on the bracket 4 contacts with the top of the test mold 12, and the second rotating mechanism 7 is adjusted. When the covering part 43 of the bracket 4 contacts and presses against the top of the test mold 12, the rotating motor is turned on, and the rotating motor drives the rotating disk 72 to rotate, and the rotating disk 72 drives the test mold 12 thereon to move, so as to realize the fixed connection between the test mold 12 and the bracket 4. The first bracket 411 and the second bracket 421 are connected simultaneously through the fixing part 44 , so that when the rotating disk 72 drives the test mold 12 thereon, the first bracket 411 and the second bracket 421 are connected to the fixing part 44 while the test mold 12 is moved.

[0063] S4: The first rotating mechanism 6 drives the lifting mechanism 5 to rotate, and the combination of the bracket 4 and the test mold 12 is located directly above the impermeability tester body 1. The lifting mechanism 5 sends the combination of the bracket 4 and the test mold 12 to the mounting seat 11, and the clamping mechanism 2 fixes the combination of the bracket 4 and the test mold 12 on the mounting seat 11; Specifically, the combination of the bracket 4 and the test mold 12 is placed on the mounting seat 11 through the lifting mechanism 5, and the driving motor 33 is turned on. The driving motor 33 drives the driving screw 32 to rotate, and the rotation of the driving screw 32 drives the driving slider 34 to move. The movement of the driving slider 34 drives the driving operating rod 31 to move, and the movement of the driving operating rod 31 drives the clamping ratchet 22 to rotate. The rotation of the clamping ratchet 22 causes the protrusion 23 on the clamping ratchet 22 to move away from the trigger rod 24, and the multiple clamping claws 21 approach each other, and the clamping claws 21 contact the test mold 12, thereby achieving the purpose of fixing the combination of the bracket 4 and the test mold 12 on the mounting seat 11, and multiple brackets 4 and test molds 12 can be fixed at the same time.

[0064] S5: The anti-permeability tester body 1 tests the test piece in the test mold 12.

[0065] The anti-seepage tester used in the related art can only test the anti-seepage performance of 6 test pieces at a time, while the anti-seepage tester body 1 described in the present application can test the anti-seepage performance of multiple test pieces at a time, thus greatly saving the investment cost of the test and having good economy.

[0066] Furthermore, it should be noted that the impermeability tester body 1 in the embodiment of the present invention has a liquid supply system and a control system; the liquid supply system can be used to provide liquid for measuring the impermeability performance into the impermeability tester body 1, and the control system can control the pressure of the liquid provided by the liquid supply system. During the test, the pressure of the liquid supply system is increased every eight hours. When the test requirements are met, the test data is obtained, and the pressure of the liquid in the liquid supply system is recorded as the pressure value of the test. During the test, when three of the end faces of the six test pieces show pressurized water seeping out, the water pressure at this time is recorded as the pressure value of the test. The control system and liquid supply system provided in the embodiment of the present invention are relatively mature technologies, and this application will not go into details here. In this application, the impermeability tester body 1 can perform impermeability performance tests on multiple test pieces at a time, that is, twelve test pieces can be tested with one device at the same time, and more test data can be read at the same time to improve test efficiency.
