Detailed description of the invention
Such as Fig. 1, shown in 4, original position soil rainfall infiltration measurement apparatus of the present utility model, including rainfall collection tank 6, described rainfall collection tank 6 be arranged over rainfall collection bucket 7, the lower section of described rainfall collection bucket 7 is provided with effusion meter 8, and the bottom of described rainfall collection tank 6 is provided with infiltrates plate 4, described in infiltrate plate 4 be arranged over the first liquid level sensor 5, the described lower section infiltrating plate 4 is provided with multiple sleeve pipe 2, is provided with soil humidity sensor 1 in described sleeve pipe 2；The side of described rainfall collection tank 6 is provided with travel(l)ing rest 10, is provided with sluice gate 11 below described travel(l)ing rest 10, and the obliquely downward of described travel(l)ing rest 10 is provided with runoff collection tank 13, is provided with the second liquid level sensor 14 in described runoff collection tank 13；
Described effusion meter the 8, first liquid level sensor 5, soil humidity sensor 3 and the second liquid level sensor 14 are all connected with measuring instrument 9.
As it is shown on figure 3, described rainfall collection bucket 7 is four, the lower section of each rainfall collection bucket 7 is equipped with an effusion meter 8.
As in figure 2 it is shown, described first liquid level sensor 5 is five, lay respectively at four angles and the center of rainfall collection tank 6.Described second liquid level sensor 14 is three.
The operation principle of original position soil rainfall infiltration measurement apparatus of the present utility model is as follows:
(1) test site needing to test is chosen, according to weather condition, the installation of assay device is carried out before rainfall, first on the soil body 1 surface according to sensor arrangement, rig is used to punch, bore diameter is slightly larger than casing diameter, inserts in boring by the sleeve pipe 2 with soil humidity sensor 3, and soil humidity sensor 3 is connected with measuring instrument 9；
(2) the rainfall collection tank 6 having installed effusion meter 8 and the first liquid level sensor 5 is put in the surface that soil humidity sensor 3 is arranged, there is the soil body surface of certain slope, the travel(l)ing rest 10 regulating scalable makes rainfall collection tank 6 horizontal positioned, the casing 6 four limit embedment shallow-layer soil body, bottom is infiltrated plate and is contacted with upper soll layer, and with liquid level sensor 5, effusion meter 8 is connected measuring instrument 9；
(3) on the soil body 1 with certain slope, digging a long groove of 1 meter at Caused by Sloping Surfaces at casing, width is advisable just to put into runoff collection tank 13, is connected with measuring instrument 9 by the second liquid level sensor 14 placed；
(4) start measuring instrument 9, carry out the debugging efforts of testing equipment, soil moisture before monitoring rainfall infiltration, by the water content of the various soil mass position that soil humidity sensor 3 can monitor, and store record numerical value, close measurement system afterwards, wait that rainfall is arrived.
(5) treat that rainfall comes interim, open test monitoring system, the rainfall of unit are can be calculated by effusion meter 8, inflow box house recorded moment water level can be monitored by the first liquid level sensor 5, and then infer storage flow, compare overhead stream and enter the flow of casing and can calculate the infiltration capacity of unit interval；
(6) when producing rainwash when, opening the sluice gate 11 installed on travel(l)ing rest 10, guide rainwash 12 to flow into runoff collection tank 13, the liquid level recorded by the second liquid level sensor 14 is high, calculates the runoff rate collected；
(7) meanwhile, measuring instrument 9 also can real time record embedment inside soil body different parts soil humidity sensor 3 measured value, seepage flow situation can be analyzed by the change of relatively identical sensor numerical value the most in the same time, the change in value of general space distribution sensor, rainfall can be analyzed at the Infiltration Law within soil, show that different depth different parts infiltrates situation change；
(8) stop infiltrating monitoring according to test requirements document concrete condition, disconnect soil humidity sensor the 3, first liquid level sensor 5, effusion meter the 8, second liquid level sensor 14 and the connection of measuring instrument, remove assay device, carry out surface wipes, put into proof box wait after natural drying and measure use next time.
Embodiment described above is only to be described preferred implementation of the present utility model; not scope of the present utility model is defined; without departing under this utility model design spirit premise; various deformation that technical solutions of the utility model are made by this area ordinary skill technical staff and improvement, all should fall in the protection domain that claims of the present utility model determine.
