Specific embodiment
As shown in Fig. 1,4, the original position soil rainfall infiltration measuring system of the present invention, including rainfall collection tank 6, described fall
The top of rain collection tank 6 is provided with rainfall collection bucket 7, and the lower section of described rainfall collection bucket 7 is provided with flowmeter 8, and described rainfall is received
The bottom of collection casing 6 is provided with and infiltrates plate 4, and the described top infiltrating plate 4 is provided with the first liquid level sensor 5, described infiltrates under plate 4
Side is provided with multiple sleeve pipes 2, is provided with soil humidity sensor 1 in described sleeve pipe 2；The side of described rainfall collection tank 6 is provided with work
Dynamic support 10, is provided with sluice gate 11 below described travel(l)ing rest 10, the obliquely downward of described travel(l)ing rest 10 is provided with runoff and collects
Casing 13, is provided with the second liquid level sensor 14 in described runoff collection tank 13；
Described flowmeter 8, the first liquid level sensor 5, soil humidity sensor 3 and the second liquid level sensor 14 are all connected with surveying
Amount instrument 9.
As shown in figure 3, described rainfall collection bucket 7 is four, the lower section of each rainfall collection bucket 7 is equipped with a flowmeter
8.
As shown in Fig. 2 described first liquid level sensor 5 is five, be located at respectively rainfall collection tank 6 four angles and in
Heart position.Described second liquid level sensor 14 is three.
The operation principle of the original position soil rainfall infiltration measuring system of the present invention is as follows：
(1) choosing needs the test site of test, according to weather condition, carries out the installation of experimental rig before rainfall, first
First on the soil body 1 surface according to sensor arrangement, punched using rig, bore diameter is slightly larger than casing diameter,
Sleeve pipe 2 with soil humidity sensor 3 is inserted in boring, soil humidity sensor 3 is connected with measuring instrument 9；
(2) the rainfall collection tank 6 having installed flowmeter 8 and the first liquid level sensor 5 is put in soil moisture to pass
The surface that sensor 3 is arranged, has the soil body surface of certain slope, the travel(l)ing rest 10 adjusting scalable face makes rainfall receive
Collection casing 6 horizontal positioned, the shallow-layer soil body is imbedded on casing 6 four side, and bottom infiltrates plate and contact with upper soll layer, by flowmeter 8 and
Liquid level sensor 5 connects measuring instrument 9；
