In addition, referring to fig. 1, in at least one alternative embodiment of the present embodiment, the top box 1 is further wrapped with a heat-insulating and sun-protecting layer, which can be sprayed on the outside of the top box 1 or covered on the outside of the top box 1, and preferably, a protective cover made of aluminum foil is used as the heat-insulating and sun-protecting layer.
Example two
The present example provides a soil gas static sampling system, which includes the soil air static sampling box provided in any one of the first to the third examples, wherein the bottom box has a plurality of bottom boxes.
In particular, with reference to fig. 1 to 4, the soil air static sampling box comprises a top box 1, a bottom box 2 and a gas sampling device; the gas sampling device is arranged on the top box 1; the top of the top box 1 is closed, the bottom of the top box 1 is provided with a first opening, the top of the bottom box 2 is provided with a second opening, and the bottom of the bottom box 2 is provided with a third opening; the portion of the top case 1 surrounding the first opening is detachably and hermetically connected to the portion of the bottom case 2 surrounding the second opening.
Before sampling, a plurality of bottom boxes 2 can be arranged at each sampling point in advance in a one-to-one correspondence manner, and during arrangement, the bottom ends of the peripheral walls of the bottom boxes 2 are inserted below the ground; during sampling, the part surrounding the first opening on the bottom of the top box 1 is hermetically connected with the part surrounding the second opening on the top of one of the bottom boxes 2, so that the soil gas at the sampling point is sealed by the top box 1 and the bottom box 2 correspondingly connected; and then sampling soil gas at the sampling point through a gas sampling device arranged on the top box 1, detaching the top box 1 from the bottom box 2 after sampling is finished, transferring the top box and installing the top box on the bottom box 2 at another sampling point, and carrying out sampling operation again.
Compared with the technical problems that in the prior art, when the same sampling box is used at each sampling point for sampling soil gas, the sampling box is not easy to arrange in a hard soil environment, so that the operation is complex, the sampling time interval is long, and the sampling efficiency is low, in the sampling process, the top box 1 and the bottom box 2 are disassembled and assembled in the transferring process of the top box 1, so that the sampling point is not influenced by soil during the conversion sampling, and the sampling device has the advantages of simplicity in operation and high sampling efficiency; simultaneously, compare with all arranging the sampling box of installing the gas sampling device who corresponds with this box in each sampling point department, but a plurality of under casings 2 of this embodiment share a top case 1, use one set of gas sampling device can accomplish the sampling work at least promptly to have the beneficial effect of saving the sampling cost.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
