The working principle of the automatic permeameter of Soil K+adsorption multiplexing energy is:
(1) it samples: sampling spoon inner wall uniformly first being applied into one layer of vaseline, is cut with sampling spoon and takes undisturbed soil sample, top, bottom
Filter paper in face paste is placed among two pieces of permeable stones, is clamped with saturation frame, is put into progress vacuum saturation in saturator and is vacuumized 1
~2 hours, satisfy water 24 hours, sand, which can be placed directly in osmotic pressure container, permeates saturation.
(2) instrument power source is opened, pressure regulator valve is loosened, when preventing from opening gas source, biggish pressure is added on sample suddenly, so
Gas source switch is opened afterwards and opens the total intake valve of instrument.
(3) it fills sample: first soil sample clamper being taken out from insulating box, then liquid storage container is infused into permeation liquid, is then beaten
It opens switching cylinder and liquid storage container goes out liquid switch, slowly adjust pressure regulator valve, make to be located at after the permeable stone below soil sample is saturated i.e. thoroughly
Water membrane is oozed out on water stone, is quickly shut liquid storage container and is gone out liquid switch.By the soil sample of saturation, the edge of a knife is upward, is placed on soil sample
On the lower cutting ring seat of clamper, puts on rubber water-proof circle and upper cutting ring seat, tightens locking cap again, then put permeable stone, it will be native
Sample clamper is put into insulating box and clamping.
(4) air compressor machine, input air pressure are opened；By depth of stratum, consolidation pressure and calorstat temperature are selected, gently
Rotation consolidation pressure regulator valve, it is basicly stable wait consolidate displacement display data, head pressure pressure regulator valve is adjusted, liquid storage container is opened and goes out liquid
Switch, observation soil sample clamper outlet line do not have bubble to continuous liquid out；Simultaneously it is important to note that liquid collection tank on balance
It not spill on balance, with anti-tamper balance.
(5) computer is opened, balance switch is then opened, opens instrument software later, inputs basic parameter, input acquisition
Period simultaneously confirms, records data.Infiltration coefficient variation is observed, after stablizing, experiment terminates, then saves, and data are kept；Root
According to requirement of experiment, different consolidation pressures are adjusted, different temperatures is tested.
(6) experiment terminates backed off after random, closes instrument software.Consolidation switching cylinder is closed, heating, blower, liquid storage appearance are closed
Device goes out liquid switch, total air inlet switch；Lay down consolidation pressure and head pressure；By consolidation emptying and liquid storage container emptying, then close
Close power supply and air compressor machine switch；Soil sample clamper is taken out, sample is taken out, soil sample clamper is cleaned and dried.Liquid collection tank is fallen
Fall clean.
