experimental device
to determine the
effect of the urban
porous surface
collecting rainwater
(ZL200810012865.4)
CN101436359
(A)—2009-05-20
The invention belongs to the technical field of research devices for water and soil conservation, and
discloses a device for establishing a water-collecting effect test for urban water permeable surfaces. The
device is characterized by mainly comprising a radial flow measuring device, a rainfall infiltration test
surface and a rainfall simulator. The radial flow measuring device comprises a collecting groove, a
collecting tank, a synchronous micro diving pump, a radial flow tank, an adjustable water control valve
and a stop watch part, and adopts a transfer type measuring method to measure radial flow. The rainfall
infiltration test surface uses a combined steel plate pile as a side wall to separate out an observation
surface; the rainfall simulator comprises a rainfall spray head, an adjustable flat base and a water supply
system; and a base bracket can keep horizontal through adjusting three lead screws respectively, so that
the device is suitable for various sloping surfaces. The water supply system mainly comprises a water
control valve, a water supply tank with primary and secondary structures, a first diving pump and a
second diving pump. The secondary tank is positioned in the primary tank. The device has the effects
and advantages of little influence on surrounding environment, accuracy and flexibility, little water
usage, and low cost

conservation
(ZL200410029760.1)
CN1563986
(A)—2005-01-12
In the invention, rainfall unit, canopy and low step face model are position at upper, middle and lower
parts of bracket. Rainfall unit includes main pipe connected to water inlet pipe and branch pipes, and
discharge pipe is in side opposite to the main pipe. Low step face model includes slope face, sidewall,
movable lateral clapboard and movable back clapboard. Four sidewalls in model are sidewall, front wall,
movable lateral clapboard and movable back clapboard. The invention includes sampler, curb and runoff
bucket are arranged at proper position. Main pipe and branch pipes are made from PVC. Raininess is
even. The invented equipment is suitable to indoor model test for larger area. The equipment is easy to
be installed
