[0023] Example 1, see appendix Figure 1 , 8 -9. A flexible clamp-type permeable concrete permeability coefficient testing device includes a water tank 1, a clamping cylinder, and a support 2. The support is placed in the water tank by four legs 21 at the four corners of its bottom surface. A support grate 22 is provided at the upper end of the support. The clamping cylinder is placed vertically in the middle of the support grate. Water flowing out of the clamping cylinder passes through the support grate 22 and enters the water tank 1. The clamping cylinder is made of silicone. A concrete block is fitted and fitted onto the lower part of the clamping cylinder. A sleeve is fitted on the outer side of the clamping cylinder. There is a tightening mechanism corresponding to the position of the concrete block. The silicone material allows the clamping cylinder to have a certain amount of elasticity. Therefore, the tightening mechanism can shrink the clamping cylinder and tighten and fix the concrete block in the clamping cylinder. The uneven sides of the concrete block will be embedded into the clamping cylinder under pressure, avoiding gaps and automatically achieving a seal. The upper part of the clamping cylinder is equipped with a water inlet pipe 31. The water used for testing is pumped into the water inlet pipe 31 and discharged into the clamping cylinder. The bottom of the water tank 1 is equipped with a drain pipe.
[0024] The water tank 1 is made of transparent plastic, allowing direct observation of the water level. A scale line 11 along the height of the outer surface of the water tank 1 provides a direct reading of the water volume. This scale line 11 allows for direct reading of the water flow, eliminating the need to remeasure the water volume in the tank 1 and improving detection efficiency. A square protective sleeve 23 is located on the upper part of the support 2, with the support grate 22 fixedly connected to the center of the protective sleeve 23.
[0025] Example 2, see appendix Figures 1-3 This embodiment is basically the same as the first embodiment, except that the clamping cylinder is a circular cylinder 3, and the concrete block inside is also circular. The tightening mechanism is a hose clamp 32. This embodiment is used for the permeability coefficient detection of the circular concrete block. After the concrete block is loaded into the clamping cylinder, the side wall of the clamping cylinder is contracted by tightening the hose clamp 32 to clamp and fix the circular concrete block in the clamping cylinder.
[0026] Example 3, see appendix Figures 4-8 This embodiment is basically the same as Embodiment 1, except that: the clamping cylinder is a square cylinder 4, and the concrete blocks inside are correspondingly square. The clamping mechanism has two clamping plates A 41 and two clamping plates B 42. The two clamping plates A are symmetrically clamped on opposite sides of the square cylinder 4. Both ends of clamping plates A 41 are provided with slots A 411. The two clamping plates A 41 are symmetrically clamped on the other two opposite sides of the square cylinder 4. The square cylinder 4 is clamped and contracted by the symmetrically arranged clamping plates. Hoops of type 32 cannot be used on the square cylinder 4. Both ends of clamping plates B 42 are provided with slots B 421. The slots A 411 at the end of clamping plate A 41 are inserted into the slots B 421 at the end of clamping plate B 42. The clamping plates A 41 and B 42 are initially fixed by the slots.
[0027] The size of the slot A 411 is larger than the thickness of the clamping plate B 42, and the size of the slot B 421 is larger than the thickness of the clamping plate A. Therefore, there is a certain amount of movement between the clamping plates A and B. This amount of movement is the amount of compression deformation of the clamping cylinder. A long screw A 43 is connected between the two ends of the two clamping plates A 41. A tightening nut A 431 is provided at the end of the long screw A. The tightening nut A 431 moves along the long screw A 43 to press against the ends of the two clamping plates A 41. A long screw B 44 is connected between the two ends of the two clamping plates B 42. A tightening nut B 441 is provided at the end of the long screw B. The tightening nut B 441 moves along the long screw B 44 to press against the ends of the two clamping plates B 42.
[0028] This embodiment is applicable to the permeability coefficient detection of square concrete blocks. The long screw and nut are used to drive the clamping plates A and B to move in opposite directions, thereby achieving the shrinking, clamping and loosening of the square concrete block inside the clamping cylinder.
