[0002] Since existing buildings are usually constructed with concrete, in order to ensure the stability and strength of the buildings, it is necessary to conduct permeability testing on the concrete used to ensure the strength of the building after construction using this type of concrete. To test the concrete, a concrete permeameter is needed.

[0003] Patent document CN206583776U discloses a concrete permeameter, "which includes a box body, a working platform on the box body, a base on the working platform, a mother mold on the base for filling recycled concrete, a drain port is provided in the base, the base is arranged in a circular ring shape, the mother mold is inserted into the base, a clamping groove is provided on the outer wall of the mother mold, and a clamping device is provided on the base which is inserted into the clamping groove to limit the mother mold in the base. The clamping device has the advantage of firmly limiting the mother mold in the base, so that it can accurately detect recycled concrete."

[0004] The above-mentioned water pump limits its position by clamping the clamping device on the base into the bottom of the mother mold, which has the advantage of firmly limiting the mother mold in the base, making it accurate in detecting recycled concrete. During the detection process, the concrete surface carries impurities and dust, which makes it easy for the impurities on the concrete surface to accumulate in the water outlet holes on the base surface during the test, thereby blocking the transport pipe inside the equipment, which requires the staff to improve their equipment.

[0027] The water source flows out from the water outlet 21 through the transport pipe 3, and is accumulated between the mounting base 2 and the mold 10. During the test, since dust and granular sand and gravel are inevitably present on the surface of the concrete block, the dust is precipitated to the surface of the mounting base 2 along the water flow, and then enters the transport pipe 3 through the water outlet 21 on the surface of the mounting base 2, and is finally blocked by the screen 7, so that the sand and gravel are accumulated on the surface of the screen 7. After the test, the mounting plate 6 is pulled to remove the block 8 on one side of the mounting plate 6 from the slot 5, so that the mounting plate 6 is disassembled. After the mounting plate 6 is disassembled, the screen 7 is disassembled together, and then the dust and sand and gravel on the surface of the screen 7 are cleaned. After the cleaning is completed, the mounting plate 6 is inserted into the slot 5 through the block 8 on one side, so that the mounting plate 6 is fixed to one side of the fixing plate 4. After the mounting plate 6 is fixed, the screen 7 is fixed to the inner wall of the transport pipe 3.

[0029] Before testing, the limiting groove 11 at the bottom of the mold 10 is first inserted into the surface of the limiting block 9 to fix the position of the mold 10. After the mold 10 is placed on the top of the mounting base 2, the bolts on the surface of the mounting base 2 are inserted into the slots 22 at the bottom of the mold 10, and then the nuts are rotated to the surface of the bolts. The mold 10 is fixed to the top of the mounting base 2 by tightening the nuts, and then the concrete block to be tested is placed in the mold 10. The sealing ring 12 can prevent water from seeping out from between the mold 10 and the mounting base 2.

[0031] During the test, the connecting pipe 23 is connected to the water source, and then the water source is transported to each set of valves 15 through the water pump 14, and then the valve 15 is turned to open the transport pipe 3, so that the water source seeps out from the water outlet 21 through the transport pipe 3, thereby impregnating the concrete. The label groove 13 on the surface of the table body 1 corresponds to the serial number 16 on the top of the valve 15.

[0033] Pull the first support plate 17 inside the second support plate 18 to adjust the first support plate 17 to a suitable height, and then use the hand wheel 20 to fix the first support plate 17 to the inner wall of the second support plate 18 through the threaded groove 19. The first support plate 17 and the second support plate 18 can support the bottom of the table body 1.

[0034] Working principle: before using the equipment for testing, first connect the connecting pipe 23 to the water source, then install the mold 10 to the top of the mounting base 2, fix the mold 10 to the top of the mounting base 2 with nuts and bolts, and then place the concrete block in the mold 10, open the valve 15, and use the water pump 14 to pump the water source in the connecting pipe 23 into the transport pipe 3, and transport the water source to the top of the mounting base 2 through the water outlet 21, so as to impregnate the concrete block in the mold 10. After the test, close the valve 15 and remove the mold 10 from the top of the mounting base 2, and observe the wet area at the bottom of the concrete block to obtain the test result.
