Synthetic water infiltration capability test apparatus for water permeable ground

The invention discloses a synthetic water infiltration capability test apparatus for water permeable ground, which mainly comprises a water source, a water tank, a water level regulator and a rainfall device. Water is pumped into the water tank by a pump from the water source, and then delivered to the rainfall device through a soft water delivery tube for the artificial rainfall. The rainfall device includes a support frame, a water chamber, water head display pipe and nozzles uniformly distributed on the lower portion of the water chamber. The water tank is provided with a water level regulator produced by martensitic bottle, and water heads for keeping the level in the water chamber of the rainfall device constant, so that the rainfall is kept at a determined strength. The test device is capable of testing synthetic water infiltration capability of not only water permeable ground in large area, but also modified water permeable ground in small area. Applying the device, inspection to the water infiltration effect of the water permeable ground pavement is greatly strengthened, and data support to the population of the water permeable ground pavement is provided. Therefore, the apparatus has evident environmental, ecological benefit and economic, social benefit.
