9. A portable measuring method for engineering measurement is characterized in that: the method comprises the following steps:
s1, placing the bottom support seat on the ground to be measured, fixing the equipment shell, and pressing the extrusion head driving device pipe into soil;
s2, when the device pipe is pressed to a specified depth, the driving motor is started to drive the hydraulic telescopic rod to rotate, the semicircular push block scrapes soil on the outer side under the action of centrifugal force, the soil on the side face falls to the extrusion head, the electric rod is started to push the collecting device out of the round hole, and the collecting device scrapes and collects the soil on the outer side along with the rotation of the hydraulic telescopic rod;
s3, the collected collecting device is retracted into the device pipe, the device pipe is driven to move to the initial position through the contraction of the hydraulic telescopic rod, at the moment, the electric push rod is started to push the soil tester on the side plate, and the soil tester is inserted into the collecting device for sampling and measuring;
s4, after the sample and the detection were accomplished, it continues to promote the collecting pipe to open electronic pole, when the collecting pipe removed to a locating position, the inner wall of device pipe was extruded to the spacing cutting ferrule in the collecting pipe outside, along with electronic pole continuation promotion collecting pipe, the thrust that the ejector pin received this moment is greater than the frictional force between ejector pin and the damping pad, then the ejector pin promotes to remove the clearance board to the collecting pipe is inside under the effect of thrust, the slip fixture block slides and drives the ejector pin rotation in spiral chute inside this moment, the rotation of ejector pin drives the brush head rotatory and carries out the scrubbing to the inner wall of collecting pipe.
