1. a kind of needle enters the uniform curing sand cylinder sample producing device of microorganism of formula, it is characterised in that:

  • It includes capillaryNeedle injection device, microbial solution pressure supply device, nutrient solution pressure supply device and discharge liquid collecting container, the capillary needle noteInjection device, microbial solution pressure supply device, nutrient solution pressure supply device and discharge liquid collecting container can be with dismantling connection, the hairsTubule needle injection device includes capillary needle and cylindric sand molding die, and sand is placed in the cylindric sand molding dieSoil sample, the capillary are needled into sand sample and inject microbial solution, and the microbial solution pressure supply device includes pressureMicrobial solution is injected capillary by force controller and solution isolating device, wherein pressure controller injection pressure to solution isolating deviceNeedle, the nutrient solution pressure supply device include water pump and reservoir, and nutrient solution injects after being pressurizeed by water pump from split cavity bottomAfter sand sample, microbial solution and nutrient solution mixing liquid collecting container is expelled at the top of sample;

    The capillary needle side trepanning is simultaneously pierced into sand sample, injects microorganism from the capillary needle side opening to sand sampleSolution;

    The microbial solution of capillary needle side opening injection generates precipitation of calcium carbonate inside sandy soil sample and after nutrient solution mixing,So as to obtain the more uniform sand cylinder sample of curing;

    The cylindric sand molding die is transparent organic glass split cavity, by two in split cavity after the completion of sand curingPetal separately can obtain sand cylinder sample;

    There are two chambers, two chambers in the solution isolating device to be separated with rubber membrane, and the rubber membrane transmits two chambersBetween water pressure, one of chamber is connected with pressure controller, another chamber fill microbial solution and with capillary needleIt is connected;

    The transparent organic glass split cavity size is outer diameter 52mm, wall thickness 1mm, high 100mm;

    The capillary needle length is 100mm, outer diameter 3mm, internal diameter 1mm, is opened in the side of needle every 5mm a pair of a diameter ofThe circular hole of 1mm.
