A concrete test block 11 adapted to the placement groove 2 is clamped between the sealing rings 10. A timer 12 is fixedly installed on the top of the installation frame 1.

[0023] Water is discharged from the water tank 5 into the pressing pipe 4. The water permeates from the pressing pipe 4 to the concrete test block 11, and finally enters the measuring cylinder 3 through the water outlet of the placement groove 2 to be measured. The timer 12 is used for timing, so that the water permeability is calculated through the time and the water permeability, and the water permeability detection work is completed.

[0024] The concrete test block 11 is placed in the placement groove 2 and is clamped and fixed by the pressing pipe 4 and the support ring 9 through the sealing rings 10. With the locking of the first connecting flange 6, the second connecting flange 7, the fixing bolt 8 and the nut, a tight clamping effect is formed, so that the water must pass through the concrete test block 11 to flow to the bottom of the placement groove 2, effectively avoiding the problem that the water flows down from the gap between the concrete test block 11 and the placement groove 2.

[0025] Connecting shafts 13 are symmetrically and fixedly connected to both sides of the placement groove 2. The connecting shafts 13 rotatably pass through the installation frame 1 and are fixedly connected with turning handles 14.

[0026] The placement groove 2 and the pressing pipe 4 are of an assembled design, so they can be disassembled. At the same time, the placement groove 2 can be rotated by the connecting shaft 13 and the turning handle 14, so that the placement groove 2 can be inverted, which is convenient for taking out the concrete test block 11 located in the placement groove 2.

[0027] An electric three-way valve 15 is fixedly connected to the bottom water outlet of the placement groove 2. One port of the electric three-way valve 15 is fixedly connected with a down pipe 16, and the down pipe 16 corresponds to the measuring cylinder 3.

A water receiving container can be placed at the end of the branch pipe 17, which is convenient for discharging the water for initial debugging.

[0028] The graduated cylinder 3 is placed at the bottom of the mounting rack 1. A positioning ring 18 is fixedly connected to the bottom of the mounting rack 1. The positioning ring 18 is adapted to the graduated cylinder 3. The graduated cylinder 3 can be conveniently placed and positioned through the positioning ring 18.

A hand-tightening bolt 21 is threadedly connected to the sliding sleeve 20. One end of the hand-tightening bolt 21 is inserted into the sliding sleeve 20 and abuts against the column of the mounting rack 1. A threaded hole for threadedly connecting the hand-tightening bolt 21 is formed in the sliding sleeve 20. At the same time, the pressing tube 4 and the water tank 5 can be driven to slide upward through the sliding sleeve 20 and locked and fixed in cooperation with the hand-tightening bolt 21, so as to conveniently control the separation of the pressing tube 4 from the placement groove 2.

[0030] A regulating valve 22 is fixedly connected to the water outlet of the water tank 5. The regulating valve 22 can control the water flow rate at the water outlet of the water tank 5.

[0031] A switch 23 is fixedly installed on the mounting rack 1. The switch 23 is electrically connected to the electric three-way valve 15 and the timer 12. The switch 23 is externally connected to a power supply.

[0032] The working principle of the present utility model is as follows:

[0033] During use, a concrete test block 11 is placed in the placement groove 2. The hand-tightening bolt 21 is further loosened. Under the action of gravity, the water tank 5 and the pressing tube 4 fall until the pressing tube 4 is inserted into the placement groove 2. At this time, the first connecting flange 6 and the second connecting flange 7 are locked and fixed through the fixing bolt 8 and the nut, so that the pressing tube 4 and the support ring 9 squeeze and fix the concrete test block 11 through the sealing ring 10, and a sealing connection effect is formed through the sealing ring 10. Water liquid is added to the water tank 5, and the graduated cylinder 3 is placed corresponding to the positioning ring 18. At this time, the electric three-way valve 15 is controlled by the switch 23 to connect the branch pipe 17 with the placement groove 2. At this time, the regulating valve 22 is opened, so that the water liquid in the water tank 5 enters the pressing tube 4 through the regulating valve 22. The water liquid in the pressing tube 4 penetrates through the concrete test block 11 and enters the bottom of the placement groove 2, and finally is discharged through the branch pipe 17. At this time, the water flow rate of the water tank 5 is controlled by the regulating valve 22, so that there is water in the pressing tube 4 without overflowing. At this time, the timer 12 is started by the switch 23 and the electric three-way valve 15 is switched, so that the down pipe 16 is connected to the placement groove 2, and the timer 12 starts timing. Thus, the penetrated water liquid enters the graduated cylinder 3 through the down pipe 16 and is collected. After a period of time, the electric three-way valve 15 is controlled by the switch 23 to be switched again, and the timer 12 is controlled to stop timing. The water permeability rate is calculated through the time recorded by the timer 12 and the water liquid volume in the graduated cylinder 3, and the water permeability rate detection work is completed.

[0034] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
