Indoor soil pressure cell tank prover

The utility model relates to an indoor soil pressure cell tank prover. The tank prover includes relief valve, manometer, admission valve, discharge valve, air guide pipeline, circuit hole, cover, can body, soil pressure cell, pneumatic rubber capsules and sand. Pneumatic rubber capsules plays the effect sealed and power of biography. Placing soil pressure cell on fixed steel sheet sand, then covering soil pressure cell with the sand, guarantee that the sand is the same with original state soil nature matter, the wire passes through the circuit hole and links to each other with collection system, plugs up the circuit hole, guarantees the gas tightness, increases the atmospheric pressure in the tank prover through the air compressor machine, and atmospheric pressure forces pneumatic rubber capsules to produce surperficial pressure to the sand again to be used in above the soil pressure cell. Soil pressure cell is given through sand upper portion was controlled to controlling the air pressure's size pressure and
