Description

Technical Field

[0001] The present invention relates to the field of concrete impermeability test equipment, and more particularly to a concrete impermeability effect test equipment for water conservancy project quality inspection. Background Art

[0002] The concrete impermeability test is a method for evaluating the impermeability performance of concrete materials. By simulating the permeation pressure conditions that concrete may encounter in actual use, the impermeability ability of concrete is tested. This test is crucial for evaluating the durability and service life of concrete. In addition, research shows that the seepage height of concrete is proportional to the square root of the product of the pressure head and the pressure application time it receives. This discovery is of great significance for understanding the relationship between the impermeability performance of concrete and pressure and time. Through this test, the impermeability performance of concrete under different water pressure and time conditions can be understood, providing a reference for actual engineering applications. The concrete impermeability test is an important test method that can not only evaluate the impermeability performance of concrete but also provide a scientific basis for the durability and service life of concrete structures. The currently commonly used equipment for the concrete impermeability test is a concrete impermeability tester.

[0003] The prior art patent document with the publication number CN119147440B provides a test device for testing the impermeability performance of concrete, which can reduce the probability of the seal sleeve sleeved on the concrete specimen shifting when testing the concrete specimen. However, when using the patent of CN119147440B, a first seal sleeve and a second seal sleeve are arranged inside the test mold. However, the seal sleeve cannot adjust its position and leave space during the installation of the specimen, so that the specimen contacts the seal sleeve during installation, generating friction and affecting its downward movement and installation. Therefore, there is an urgent need for a concrete impermeability effect test equipment for water conservancy project quality inspection. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems that the existing seal sleeve cannot adjust its position and leave space during the installation of the specimen, so that the specimen contacts the seal sleeve during installation, generating friction and affecting its downward movement and installation; when the test mold and the base are installed, they are fixed by bolts, but the sealing performance of this fixing method is poor, prone to water leakage; and during the test period of the specimen, the experimenter cannot always stay beside the impermeability tester to detect the water seepage situation, so that when the water seepage problem occurs, it cannot be discovered in time.

[0008] The detection structure includes a detection cover. A magnetic attraction ring is arranged at the bottom of the detection cover, and a water immersion sensor is installed at the top of the inner wall of the detection cover. A probe is installed at the bottom of the water immersion sensor, and a display paper strip is arranged on one side of the water immersion sensor. A wetting paper piece is arranged at the bottom of the display paper strip.

[0009] Preferably, a valve is installed on the anti-seepage instrument main body. An outlet is opened inside the base, and a sealing ring is arranged at the top of the base. A test piece is clamped inside the test mold.

[0010] Preferably, the movable ring is slidably connected to the test mold through the slider and the chute. An activity groove matching with the connecting block is opened on the test mold, and a sealing groove matching with the sealing sleeve is opened on the inner wall of the test mold.

[0011] Preferably, the unfolding frame is fixedly connected to the sealing sleeve through the connecting block, and the number of the unfolding frames is multiple. An inclined surface cone is arranged at the bottom of the plug board.

[0012] Preferably, the clamping block is clamped and connected to the clamping groove. The rubber pad is fixedly connected to the base through glue. An annular groove matching with the clamping ring is opened on the outer side of the base.

[0013] Preferably, the positioning plug is clamped and connected to the positioning groove, and the number of the positioning grooves is two. The threaded rod is movably connected to the positioning plug through a bearing.

[0016] Preferably, a shrinkage groove matching the display paper strip is formed at the top of the detection cover, and a storage battery is installed on one side of the water immersion sensor.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: First, by setting the sealing sleeve, the unfolding frame, the insertion plate and the movable ring, the movable ring moves downward on the outside of the test mold, and a plurality of insertion plates at its bottom end are inserted into the gap between the test mold and the two unfolding frames through the inclined cones at the bottom end, so that after the two unfolding frames are subjected to extrusion pressure, they move outward, and drive the sealing sleeve to stretch and expand outward through the connecting block, thereby increasing the inner area of the sealing sleeve, facilitating the insertion of the test piece into the test mold, and after insertion, pulling out the insertion plate, the sealing sleeve rebounds and contracts, so as to fit on the outer wall of the test piece to ensure its sealing performance with the test mold.

[0018] Second, by setting the mounting seat, the base, the engaging block, the engaging groove, the rubber pad, the airbag ring, the extrusion block and the positioning insert, then moving the test mold above the base, and making the mounting seat at the bottom end of the test mold fit with the base and the rubber pad, the engaging block at the bottom of the mounting seat is inserted into the engaging groove inside the base, and the engaging ring at the bottom end of the mounting seat is inserted into the annular groove outside the base. At the same time, the extrusion block on the inner wall of the mounting seat moves downward to squeeze the airbag ring, so that the airbag ring is squeezed and the mounting gap between the mounting seat and the base approaches, realizing the shielding of the gap. Finally, screw the threaded rod, the threaded rod rotates on the support plate through threads, drives the positioning insert to move toward one side of the base through the bearing, and the limiting rod at one end of the positioning insert moves on the support plate. After the positioning insert moves, it is inserted into the positioning groove on one side of the mounting seat and the base, so that the mounting seat and the base are secondarily engaged through the positioning insert, thereby ensuring the sealing performance after the mounting seat and the base are mounted in multiple ways.

After the test mold is installed, the detection cover is fixed to the top of the test mold through the magnetic suction ring at the bottom end, and the display strip and the wetting paper sheet are lowered, so that the wetting paper sheet contacts the top end of the test piece, and the probe on the water immersion sensor installed inside the detection cover contacts the top of the test piece, which is convenient for detection. After the appearance of water droplets is detected, the detection signal is immediately converted into an electrical signal and transmitted to the device end to send an alarm message. At the same time, when water droplets appear, the wetting paper sheet will be continuously wetted. After the wetting paper sheet is completely soaked, the water will continuously spread to the display strip. The wetting paper sheet and the display strip will continuously increase their gravity due to wetting, and thus fall off and separate from the contraction groove. When the surrounding experimenters cannot see the display strip from the top of the detection cover, it can be known that the test piece has water seepage. The two detection methods operate simultaneously to ensure that when the test piece has water seepage, it can be discovered in time. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Please refer to Figures 10 - 11, a test device for the anti-seepage effect of concrete used in water conservancy project quality inspection. The detection structure 10 includes a detection cover 1001. A magnetic suction ring 1002 is provided at the bottom end of the detection cover 1001. The inner wall top of the detection cover 1001 is equipped with a water immersion sensor 1003. A probe 1004 is installed at the bottom end of the water immersion sensor 1003. A display paper strip 1005 is arranged on one side of the water immersion sensor 1003. A wetting paper sheet 1006 is provided at the bottom end of the display paper strip 1005. The detection cover 1001 and the test mold 7 are magnetically fixed through the magnetic suction ring 1002. The water immersion sensor 1003 and the detection cover 1001 are fixedly installed by bolts. A contraction groove matching the display paper strip 1005 is opened at the top end of the detection cover 1001. A storage battery is installed on one side of the water immersion sensor 1003. After the test mold 7 is installed, the detection cover 1001 is fixed at the top end of the test mold 7 through the magnetic suction ring 1002 at the bottom end, and the display paper strip 1005 and the wetting paper sheet 1006 are lowered, so that the wetting paper sheet 1006 contacts the top end of the test piece 11, and the probe 1004 on the water immersion sensor 1003 installed inside the detection cover 1001 contacts the top of the test piece 11, thus facilitating detection. After detecting the appearance of water droplets, the detection signal is immediately converted into an electrical signal and transmitted to the device end to send an alarm message. At the same time, when water droplets appear, the wetting paper sheet 1006 will be continuously wetted. After the wetting paper sheet 1006 is completely soaked, water will continuously spread to the display paper strip 1005. The wetting paper sheet 1006 and the display paper strip 1005 will fall due to the continuous increase in gravity caused by wetting and separate from the contraction groove. When the surrounding experimenters cannot see the display paper strip 1005 from the top of the detection cover 1001, it can be known that the test piece 11 has seepage. The two detection methods run simultaneously to ensure that when the test piece 11 has a seepage situation, it can be discovered in time.

[0026] Working principle: When the present invention is in use, after the specimen 11 is formed for a certain period of time, the impermeability test can be carried out. At this time, the movable ring 801 is pushed through the inner slider 802 and the chute 803 on the outer wall of the test mold 7, and moves downward on the outside of the test mold 7. When the movable ring 801 moves downward, a plurality of inserting plates 804 at its bottom end are inserted into the gap between the test mold 7 and the two sets of unfolding frames 806 through the inclined surface cones at the bottom end. As the inserting plates 804 are continuously inserted downward, after the two sets of unfolding frames 806 are subjected to extrusion pressure, they move outward, and drive the sealing sleeve 808 to stretch and unfold outward through the connecting block 807, thereby increasing the inner area of the sealing sleeve 808. Then, the specimen 11 can be inserted into the test mold 7, and the specimen 11 is completely pressed into the test mold 7 through the pressure device. After the specimen 11 is fixed, the movable ring 801 is lifted upward, so that the inserting plates 804 are withdrawn from the inside of the unfolding frame 806. Then, the unfolding frame 806 automatically returns to its original position under the elastic stretching of the sealing sleeve 808, and the sealing sleeve 808 contracts and fits on the outer wall of the specimen 11, realizing the positioning and installation of the two sealing sleeves 808, ensuring the sealing between the specimen 11 and the test mold 7. Then, the test mold 7 is moved above the base 3, and the mounting seat 6 at the bottom end of the test mold 7 is fitted with the base 3 and the rubber pad 903. The engaging block 901 at the bottom of the mounting seat 6 is inserted into the engaging groove 902 inside the base 3, and the engaging ring 906 at the bottom end of the mounting seat 6 is inserted into the annular groove outside the base 3. At the same time, the extrusion block 904 on the inner wall of the mounting seat 6 moves downward to squeeze the airbag ring 905, so that the airbag ring 905 is squeezed and the mounting gap between the mounting seat 6 and the base 3 is closed, realizing the shielding of the gap. Finally, the threaded rod 910 is rotated. The threaded rod 910 rotates on the support plate 911 through the thread, drives the positioning plug 908 to move toward the base 3 through the bearing, and the limiting rod 909 at one end of the positioning plug 908 moves on the support plate 911. After the positioning plug 908 moves, it is inserted into the positioning groove 907 on one side of the mounting seat 6 and the base 3. Then, the mounting seat 6 and the base 3 are secondarily engaged through the positioning plug 908, thereby ensuring the sealing of the mounting seat 6 and the base 3 after installation in multiple ways. After the test mold 7 is installed, the detection cover 1001 is fixed to the top of the test mold 7 through the magnetic suction ring 1002 at the bottom end, and the display strip 1005 and the wetting paper 1006 are lowered, so that the wetting paper 1006 contacts the top end of the specimen 11, and the probe 1004 on the water immersion sensor 1003 installed inside the detection cover 1001 contacts the top of the specimen 11, facilitating detection. After detecting the appearance of water droplets, the detection signal is immediately converted into an electrical signal and transmitted to the device end to send an alarm message. At the same time, when water droplets appear, they will continuously wet the wetting paper 1006. After the wetting paper 1006 is completely wet, the water continuously spreads to the display strip 1005. The wetting paper 1006 and the display strip 1005 increase their gravity due to wetting and thus fall, separating from the contraction groove. When the surrounding experimenters cannot see the display strip 1005 from the top of the detection cover 1001, it can be known that the specimen 11 has seepage.The two detection methods run simultaneously to ensure that when water seepage occurs in the test piece 11, it can be detected in time.
