1.The upper part of the water permeability meter is a transparent organic glass measuring cylinder,volume600mL,There are scales on it,in100mLand500mLThere are thick markings at the location,10mmheight is20mL;The lower part is made of transparent organic glasstube, outer diameter140mminner diameter125mm,Connect to the upper part through the connecting seat,lower partFixed on the base;Inner diameter of the opening below the base150~151mm,outer diameter300mm,There is a water outlet hole in the middle above, with a diameter of25mm±2mmwater seepage meterInstall a piston internally,The bottom is a rubber plug, Install a liquid level sensor inside the water seepage meter,It is connected to an external display,Real time display of liquid level height on the monitor during the experiment,And permeability coefficient.(Automatic calculation)Permeability coefficient）

2.ring toss:metal ring,The bottom is the cutting edge,The outer diameter is149-150mm,width5mm,The thickness of the upper wall is about5mm,The main purpose is to prevent the sealing material from being squeezed into the testing surface, resulting in inconsistent water leakage area.3.plastic ring:inner diameter150mm,outer diameter300mm.

4.counterweight:The total mass of the two pieces is about10kg.
