The main sampling methods for soil gas include the closed chamber method, the diffusion bottle method, and the hollow tube method, but all of these methods have drawbacks. The diffusion bottle method seriously destroys the physical properties of the soil and cannot reliably reflect the characteristics of the soil gas, and the hollow tube method is difficult to spread to outdoor sampling. Whether by drilling or excavation, it requires external force to reach deep into the soil, seriously destroying the physical properties of the soil, and also requires strict timing in the gas suction process, which reduces the efficiency of gas extraction. Therefore, it is of practical significance to develop a portable collection device for soil gas samples. Traditional closed chambers have a large volume, large weight, and are difficult to transport. In addition to high processing costs, various experimental error factors, such as variations in air pressure inside and outside the chamber, reduce observation accuracy.

Taking Embodiment 1 as an example, when actually using the device, the entire device is set at a desired sampling point, and the output shaft of the first motor 25 rotationally drives the rotation block 26 and the connecting rod 27 to rotate the device. The block 26 rotates within the rotation groove 222, and thereby the screw type ejector 24 rotates due to the action of the restriction boss 271, and the screw type ejector 24 moves downward while being screwed by the screw type restraint cylinder 23. , at the same time, the connecting rod 27 is slidably connected to the threaded ejector 24 to prevent downward movement of the fixed block 22 and the rotating block 26, and the auger boring rod 28 is coupled to the threaded ejector 24. was bored underground,
The auger boring rod 28 stabilizes the whole device when it is bored underground, the sampling rod 41 with the sampling part 6 is put into the sampling restraint tube 13, the electric telescopic rod 36 is extended, and the locking block connecting rod 34 is inserted into the sampling restraint tube 13. The locking block 35 at one end passes through the sliding groove 333 and comes into contact with the outer surface of the sampling rod 41, and the collection rod 41 is pinched by the cooperation of the four locking blocks 35, and then the electric push rod 31 The locking block 35 of the locking means 33 drives the sampling rod 41 to be inserted into the underground, and when the electric push rod 31 is extended to the limit, the electric telescopic rod 36 is retracted, the four locking blocks 35 are disengaged from the collection rod 41, and then the electric push rod 31 is retracted to the shortest distance,
By repeating the above steps multiple times, the sampling rods 41 are gradually inserted underground, and when it is necessary to butt together a plurality of sampling rods 41, the engagement connecting rod 45 at the lower end of one sampling rod 41 is The engagement block 451 at the lower end of the engagement connecting rod 45 passes through the removal slot 431, and then the upper extraction rod 41
The knob 47 is rotated to rotate the upper end surface of the engagement block to below the stop ring 43.
rotates to rotate the rotating shaft 46, thereby causing the eccentric cam 48 to rotate, and when the eccentric cam 48 rotates, the protruding end projects the ejecting plate 49 upward and engages. The connecting rod 45 is moved upward, and the engaging connecting rod 45 compresses the spring 453 while moving upward in the fourth through hole 441 of the restraining block 44, and the engaging block 451 is moved under the retaining ring 43. The gas collection tube 42, which is in close contact with the end face and then adjacent, is connected in a sealing manner.

In the initial position, the closing fitting block 66 is embedded in the obturator hole 61, and the outer surface of the sampling part 6 becomes a perfect and smooth outer conical surface, and when the sampling part 6 reaches the sampling position, the sealing cone telescopic rod 68 is retracted, and the closure fitting block 66 is disengaged from the closure hole 61, at which time the ventilation hose 62 is communicated with the outside, and the soil gas passes through the ventilation hose 62 to the gas collection buffer ring 6.
3, the soil gas in the gas collection buffer ring 63 enters the gas collection manifold 55 via the gas collection tube 42, and the soil gas in the gas collection manifold 55 further passes through each gas collection branch pipe 54 to each gas collection. The soil gas is transported to the inside of the vacuum bottle 51, thereby completing the collection of the soil gas.
