Abstract

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.

Description

technical field

[0001] The invention belongs to the technical field of water and soil conservation research devices, and relates to a device for establishing a water collection effect test of an urban permeable surface. It is a set of rainfall simulation test system suitable for urban road surfaces. The device can measure the permeability of the underlying surface on site. , to obtain relevant data on rainwater harvesting. Background technique

[0002] The building components that construct the urban permeable surface, such as permeable pipes and permeable concrete blocks, are relatively large in volume, and it is obviously impossible to directly observe the seepage effect of the permeable surface with conventional instruments for observing the soil infiltration rate; Form, referring to the measurement method of soil water seepage rate, design a special test device for observation.
