5. The waterproof device of examining of engineering building material of claim 4, characterized in that: the elastic buffer part comprises a shell, an elastic piece and a pressing plate matched with the rotating shaft; the shell is provided with a mounting groove, the direction of the mounting groove is downward, one end of the elastic piece is fixedly mounted at the bottom of the mounting groove, and the other end of the elastic piece is fixedly connected with the pressing plate; the pressing plate is detachably connected with the rotating shaft.
6. The engineering building material waterproof inspection device according to claim 1, characterized in that: a bottom plate of the water collecting box is provided with a stabilizing assembly for stably driving the driving cylinder to longitudinally drive; the stabilizing assembly comprises a plurality of stabilizing rods which are uniformly distributed on the extrusion plates on two sides of the air rod; one end of the stabilizer bar is fixedly arranged on the extrusion plate, and the other end of the stabilizer bar penetrates through the bottom plate of the water collecting box; and a baffle for preventing water leakage is arranged at the joint of the stabilizer bar and the first air bar and the water collecting box bottom plate.
7. A waterproofing detection method according to any one of claims 1 to 6, comprising the steps of:
s1: feeding: firstly, a material to be detected is installed in a mounting fixture, and then the mounting fixture is installed in a sliding groove in the inner wall of a water collection box;
s2: fixing a detection object: the clamp is propped upwards by the extrusion unit until the material to be measured on the clamp rises to be in contact with the flexible sealing element; forming a sealing effect;
s3: simulating water drainage: the water in the water accumulating tank is intermittently sucked into the water storage tank through a time relay and a water pump, so that the water discharging operation is simulated;
s4: and (3) detection: filling air into the flexible sealing ring on the sealing element, and then confirming the reaction condition of the reagent/test paper in the kit; determining whether a water leak will occur;
s5: and (3) recovering waste water: after the detection is finished, the waste water is recycled through the water accumulating box on the water circulating device, and then the circulation detection effect is carried out through the simulated water flow again.
