Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below embodiment of the present utility model is elaborated; the present embodiment is implemented take technical solutions of the utility model under prerequisite; provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Referring to Fig. 1, a kind of Rock And Soil water absorption test device that the present embodiment provides, comprise base 1, water circulation system and water level control system, on base 1, be provided with the first support 2 and the second support 3 that protrude upward, water circulation system comprises water leg 4, overflow groove 5, water pump 8, water injection pipe 7 and recirculatory pipe 9, water leg 4 is fixed on base 1, overflow groove 5 is arranged on the upper end of the first support 2, in overflow groove 5, by a vertical clapboard 6, be divided into left groove and right groove, the height of vertical clapboard 6 is less than the peripheral height of overflow groove 5, water leg 4 is communicated to right trench bottom by water injection pipe 7, water pump 8 is set on water injection pipe 7, left trench bottom is connected to water leg 4 by recirculatory pipe 9, water level control system comprises balance tank 12, aqueduct 10 and liquid flowmeter 11, and balance tank 12 is arranged on the upper end of the second support 3.In balance tank 12, be provided with horizontal baffle 13, on horizontal baffle 13, be evenly provided with the hole of a plurality of up/down perforations, horizontal baffle 13 upper surfaces and vertical clapboard 6 tops are positioned on same level line, horizontal baffle 13 upper surfaces are used for placing Rock And Soil sample 14, between horizontal baffle 13 upper surfaces and Rock And Soil sample 14, are provided with filter paper.Right trench bottom, the other end that aqueduct 10 one end are communicated with overflow groove 5 are communicated with balance tank 12, and on aqueduct 10, are provided with the liquid flowmeter 11 that detects flow.Liquid flowmeter 11 is selected instantaneous flowmeter or flow quantity recorder as required, when needs obtain Rock And Soil sample 14 accumulation water absorbing capacitys, adopt over time flow totalizer during characteristic, when needs obtain the instantaneous rate of water absorption of Rock And Soil sample 14, adopt over time instantaneous flowmeter during characteristic.
