Background technology
Gas in existing monitoring well collection monitoring soil, builds monitoring well program complexity, can only once monitor one
The soil horizon gaseous contamination situation of depth, the main flux for determining soil gas, reaction be unit area gas gross, such as
It is layered collection monitoring soil gas and may result in that whole monitoring cost is high, time-consuming, collection measurement result has the defects of deviation；
The method of another middle collection monitoring is to dig soil from the ground to collect in plastic packaging bag, then is analyzed and detected with analyzer, so
, larger error be present in the actual conditions in soil body position where the pedotheque of collection monitoring can not represent initial soil.Institute
It is easy and effective to be layered the more above-mentioned method of collection monitoring soil gas using positioning heeling-in sampling apparatus, but positioning at present
Heeling-in sampling apparatus is generally disposable harvester, it is impossible to gathers pedotheque whenever and wherever possible, it is impossible to realizes to fixed bit
The long-term collection monitoring of the soil at place is put, and this apparatus structure is all complex.
Utility model content
The purpose of this utility model is to provide a kind of soil gas layering harvester, solves asking in background technology
Topic, the structure of this soil gas layering harvester are simple；Collection soil gas can be layered；And it can realize for a long time, at any time
Sampling analysis；Monitoring to soil gas is accurate, efficiency high simple to operate.
In order to realize the above object the technical solution adopted in the utility model is：A kind of soil gas is layered harvester,
Including filter layer, separation layer, collector and airway tube, described filter layer is arranged on the lowermost end of the device, described filtering
Layer is alternately arranged with separation layer, and described collector is separately positioned in filter layer, and the top of the device is provided with cement mortar
Sealing, described cement mortar sealing cover the filter layer of the top, and one end of described collector and described airway tube connects
Connect, described airway tube runs through the inside of the device, and the other end indwelling of described airway tube is in the cement mortar sealing
Upper end, the indwelling end of the airway tube are additionally provided with identification number.
It is of the present utility model to have technical effect that：This soil gas is layered harvester, structure and simple to operate；Can be right
The soil of fixed position is acquired monitoring for a long time, the soil gas of collection can accurately at reflection soil gas situation.
