Description

Technical Field

[0001] This utility model relates to the technical field of cement test block testing equipment, and in particular to a cement test block permeability testing equipment. Background Technology

[0002] A concrete permeameter is an instrument used to determine the impermeability of sealed concrete. It is designed based on the hydraulic principle, with an electric motor driving a water pump to apply pressure. The pump is connected to a pressure vessel, control valve, and test mold base through pipelines. The pressure is output from the water pump into the pressure vessel and then delivered to each cement test block system for loading tests.

[0003] The announcement number is CN206583776U, and the name is a concrete permeameter. It includes a box, a working platform on the box, a base on the working platform, and a master mold for filling recycled concrete on the base. The base is provided with a drain outlet and is designed as a ring. The master mold is inserted into the base. A snap-fit ​​groove is opened on the outer wall of the master mold. The base is provided with a snap-fit ​​device that is inserted into the snap-fit ​​groove to limit the master mold in the base. By covering the top of the master mold, the recycled concrete is prevented from falling out of the master mold during testing, so as to better detect the performance of recycled concrete.

[0004] Before placing the cement test block into the master mold, a sealant is usually applied to the side of the cement test block to prevent premature water seepage at the edges. Then, a sealing ring is placed over the sealant to reduce the gap between the side of the cement test block and the inner wall of the master mold. The sealing ring needs to be placed on the cement test block for each test, and the sealing ring needs to be stretched and then placed on the cement test block during the process. The sealing ring needs to be removed when the penetration test is finished. This sealing process is quite complicated and not conducive to the quick replacement of cement test blocks.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a cement test block permeability testing device includes a testing device 1 and a pressure device 2. The testing device 1 includes a frame 11, on which multiple lower support cylinders 12 are evenly and vertically arranged horizontally on the top surface of the frame 11, and the multiple lower support cylinders 12 are fixed through the top surface of the frame 11. A first rubber pad 121 is fixed on the inner wall of the multiple lower support cylinders 12. Multiple pressure devices 2 are provided, and the multiple pressure devices 2 are arranged one-to-one with the multiple lower support cylinders 12. The pressure device 2 includes a sliding frame 21. The sliding frame 21 is vertically fixed to the top surface of the frame 11, and a liquid-filling component 23 is vertically slidably installed on the sliding frame 21. The liquid-filling component 23 includes a sleeve 231, a second rubber pad 233 is fixed on the inner top surface of the sleeve 231, and a liquid-holding measuring cylinder 234 is vertically connected and fixed to the top of the sleeve 231. A cement test block 3 is vertically inserted into the lower support cylinder 12, and the upper part of the cement test block 3 is vertically inserted into the sleeve 231. The bottom ends of the multiple lower support cylinders 12 of the frame 11 are all vertically provided with liquid-receiving points. Measuring cylinder 13, with the liquid receiving measuring cylinder 13 threadedly connected to the lower support cylinder 12, is used in conjunction with multiple liquid receiving measuring cylinders 234 threadedly assembled at the bottom of the lower support cylinder 12 of the frame 11. Then, the cement test block 3 is vertically inserted into the lower support cylinder 12. Next, the liquid feeding component 23 on the sliding pressure component 2 drives the sleeve 231 to be fitted onto the cement test block 3, pressing the cement test block 3 onto the lower support cylinder 12. Then, the liquid in the liquid receiving measuring cylinder 234 is discharged into the sleeve 231 under pressure. The liquid passes through the cement test cylinder 12. The cement block 3 permeates downwards and falls into the liquid receiving cylinder 13. Based on the decrease in liquid in the liquid holding cylinder 234 and the amount of liquid in the liquid receiving cylinder 13, the permeability of the cement block 3 can be calculated. Therefore, when installing the cement block 3, the upper and lower ends of the cement block 3 respectively squeeze the second rubber pad 233 and the first rubber pad 121 in the sleeve 231 and the lower support cylinder 12, thereby sealing both ends of the cement block 3 and preventing leakage to maintain the sealing during the test. This installation method has fewer steps and is convenient.

[0024] Please see Figure 4 and Figure 5 A slider 232 is horizontally fixed on the outer circumference of the sleeve 231, and the slider 232 is slidably mounted on the slide frame 21. A screw 22 is vertically threaded through the top surface of the slide frame 21, and the bottom end of the screw 22 is rotatably connected to the slider 232. In order to ensure the cement test block 3 is tested for permeability, the screw 22 on the slide frame 21 is rotated, and the screw 22 pushes the slider 232 on the sleeve 231 to slide vertically down. The sleeve 231 is fitted on the outside of the cement test block 3, and at the same time, the cement test block 3 is squeezed in the lower support cylinder 12. When pressure is applied, the upper and lower ends of the cement test block 3 respectively squeeze the second rubber pad 233 and the first rubber pad 121 in the sleeve 231 and the lower support cylinder 12, thereby sealing the two ends of the cement test block 3 and preventing leakage to maintain the sealing during the test.

[0025] Please see Figure 5 The liquid measuring cylinder 234 and the top of the sleeve 231 are connected and fixed through the liquid inlet cylinder 235. A valve 236 is fixed on the liquid inlet cylinder 235 of the liquid measuring cylinder 234 and the sleeve 231. The top of the liquid measuring cylinder 234 is open, and a piston block 239 is vertically inserted into the open end of the liquid measuring cylinder 234. A bracket 237 is vertically fixed on the top of the liquid measuring cylinder 234, and a hydraulic rod 238 is vertically fixed on the bracket 237. The output end of the hydraulic rod 238 is fixed on the top surface of the piston block 239. In use, the valve 236 on the liquid inlet cylinder 235 is opened, and the hydraulic rod 238 on the bracket 237 of the liquid measuring cylinder 234 is activated to push the piston block 239 to slide in the liquid measuring cylinder 234, squeezing the liquid into the sleeve 231 for permeation detection.

[0026] Working principle: In use, multiple liquid-containing measuring cylinders 234 are threadedly assembled onto the bottom end of the lower support cylinder 12 of the frame 11. Then, the cement test block 3 is vertically inserted into the lower support cylinder 12. Then, the liquid-filling component 23 on the sliding pressure component 2 drives the sleeve 231 to be fitted onto the cement test block 3, squeezing the cement test block 3 onto the lower support cylinder 12. Then, the liquid in the liquid-containing measuring cylinder 234 is discharged into the sleeve 231 under pressure. The liquid permeates downward through the cement test block 3 and falls into the liquid-receiving measuring cylinder 13. The permeability of the cement test block 3 is calculated based on the decrease in liquid in the liquid-containing measuring cylinder 234 and the amount of liquid in the liquid-receiving measuring cylinder 13.
