Specific embodiment
The principle and feature of the present invention are described below in conjunction with accompanying drawing, example is served only for explaining the present invention, and
It is non-for limiting the scope of the present invention.
As shown in figure 1, a kind of system for obtaining gas in soil, including harvester and collection device, the collection dress
Put and be embedded in soil, the collection device is outside soil, and the harvester connects institute by silica gel appendix 5
Collection device is stated, the gas for being gathered simultaneously is transported to the collection dress by the gas of the harvester collection respective layer position soil
Put and save, it is specific as follows：
The harvester includes 4, two collection tubes 1 of the first glass tube and a delivery pipe 2；Two collection tubes 1
It is embedded in soil, netted air admission hole, and one end of two collection tubes 1 is equipped with two collection tubes 1
Closing, the other end of two collection tubes 1 is got up by the two of which interface level docking of three-way connection 3, described defeated
The 3rd interface of one end connection three-way connection 3 of pipe 2, the other end of the delivery pipe 2 is sent to be vertically up to
Outside soil；The two ends of the delivery pipe 2 are provided with sealing-plug, and first glass tube 4 is in the delivery pipe 2 and through two
The sealing-plug, in the upper end of first glass tube 4 one end of the silica gel appendix 5 is connected.First glass tube 4 is arranged
In delivery pipe 2, the first glass tube 4 can be avoided from being extruded by soil and damaged；If directly arranged in delivery pipe 2 in addition
Silica gel appendix 5 has following two：
1. the silica gel appendix 5 of quality of rubber materials is easily aging in the wild, will change within general 1 year；2. quality of rubber materials is defeated
Tracheae 5 is easily flattened, and causes gas to be difficult to gather.
The collection device includes inverted gas bottle 6, the second glass tube 10, the 3rd glass tube 11, the and of silica gel air inlet pipe 7
Silica gel drainpipe 8；The bottle sealing of the gas bottle 6 has rubber stopper, and described one end of second glass tube 10 is in the gas bottle 6
Bottleneck outside, the other end of second glass tube 10 is after the rubber stopper in the gas bottle 6 and near bottle
At the position of mouth, outside the bottleneck of the gas bottle 6, the 3rd glass tube 11 is in addition for described one end of 3rd glass tube 11
One end is after the rubber stopper in the gas bottle 6 and at the position of bottom of bottle；Nothing is full of in the gas bottle 6
The water body of foreign gas；The one end of one end of the silica gel drainpipe 8 with second glass tube 10 outside the bottleneck of gas bottle 6
Connection, the other end of the silica gel drainpipe 8 is extended downwardly；One end of the silica gel air inlet pipe 7 and the 3rd glass tube 11
Outside the bottleneck of gas bottle 6 one end connection, the other end of the silica gel air inlet pipe 7 extend downwardly after with the silica gel gas transmission
The other end connection of pipe 5.Second glass tube 10, the 3rd glass tube 11 are set in gas bottle 6, are because that glass tube can keep perpendicular
Vertical state, if entered in gas bottle 6 directly through rubber stopper using silica gel air inlet pipe 7 and silica gel drainpipe 8, quality of rubber materials
Silica gel air inlet pipe 7 and silica gel drainpipe 8 cannot keep upright state, and affect the collection of draining or gas in gas bottle 6.
Sealing is respectively equipped with silica gel appendix 5 described above, the silica gel air inlet pipe 7 and the silica gel drainpipe 8
Folder 9.
A complete gas collecting and collected process is described below：
It is the assembling such as collection tube 1, the glass tube 4 of delivery pipe 2 and first by gas collector before soil gas is gathered
The soil horizon for being put in different depth is buried after good, and the length of collection tube 1 is adjusted according to gas collecting amount.After a period of time, soil is treated
Gas collection can be carried out after earth Stability Analysis of Structures, soil gas exchange equilibrium.Must be by gas bottle 6 before collection device use
Water body full of free from admixture gas, silica gel appendix 5 is connected with the silica gel air inlet pipe 7 of harvester, then first that silica gel is defeated
Tongs on tracheae 5 and silica gel drainpipe 8 is opened, then the tongs in silica gel air inlet pipe 7 is opened, the water in gas bottle 6
Body flows out under gravity after the second glass tube 10 from silica gel drainpipe 8.Along with the stream of water body in gas bottle 6
Go out, the gas in soil first passes through air admission hole and enters into collection tube 1, then sequentially passes through the first glass tube 4, the and of silica gel appendix 5
Silica gel air inlet pipe 7, finally enters into from the 3rd glass tube 11 and is saved in gas bottle 6.Treat that water level almost soon drops to second
During the position at the top of glass tube 10, the tongs closed in silica gel drainpipe 8, silica gel appendix 5, silica gel air inlet pipe 7 successively, and
Disconnect the connection of silica gel appendix 5 and silica gel air inlet pipe 7.So far, gas collecting and collect task complete.
The foregoing is only presently preferred embodiments of the present invention, not to limit the present invention, all spirit in the present invention and
Within principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
