Abstract
The utility model discloses a many degree of depth of single injection formula soil gas collection system, including sample thief, air duct, air sampling bag and aspiration pump, its characterized in that: the sample thief is including the body and conical drill bit that are the cylinder, the body is inside to be become four regions by vertical wall piece equipartition of two mutually perpendicular, an air inlet is respectively established in four regions, four air inlets are in on the different vertical height respectively, be equipped with the filter in the air inlet, round cover plate is established at the top of body, the apron is equipped with four ventholes, respectively establish an air duct in four ventholes, air duct one end gets into regional insidely, and the other end stretches into air sampling bag, the aspiration pump passes through the exhaust tube and is connected with air sampling bag. The utility model provides a people to soil when the soil gas sample is gathered to reducible many degree of depth is the disturbance, improves the soil gas collection system of sample collection's accuracy.
Description
Technical field
This utility model belongs to Geotechnical Engineering technical field of mechanical equipment, and particularly relate to a kind of single injection but can be simultaneously
Gather the device of different depth soil gas sample.
Background technology
At present, what soil pollution and pollution were likely to result in be detrimental to health etc., and problem is increasingly subject to extensive concern.
Science and accurate acquisition pedotheque are the key links understanding soil environment quality.Accurate acquisition thin solum
Gaseous sample also analyzes contained volatile organic contaminant content in gas, is having of assessment soil pollution risk
Effect means.Existing soil gas harvester uses repeatedly injection to obtain different depth soil gas mostly
Sample, and by an injection obtain different depth soil gas sample device often sample between lack
Corresponding quarantine measures cause sample data not accurate enough.
Utility model content
For solving problem above, task of the present utility model is to provide one can reduce many degree of depth collection SOIL GAS
Artificial disturbance to soil during body sample, improves the soil gas harvester of the accuracy of sample collecting, tool
Body is realized by techniques below scheme:
A kind of single penetration type many depth soil gas harvester of the present utility model, including sampler (1),
Airway (2), air sampling bag (3) and air pump (4), it is characterised in that: described sampler (1)
Including in cylindrical body and cone drill bit, described tubular body by the orthogonal longitudinal direction of two panels every
Part average mark is divided into four regions, and described four regions respectively set an air inlet (5), described air inlet (5)
Being located on the tube wall of body, described four air inlets (5) are respectively in different vertical heights, described in enter
Being provided with filter in QI KOU (5), described filter can isolate the water in soil, and the top of described body sets circle
Shape cover plate, described cover plate is provided with four ventholes, and described four ventholes correspond respectively to four overlying regions,
Respectively setting an airway (2) in described four ventholes, described airway (2) one end enters intra-zone,
The other end stretches into air sampling bag (3), and described air pump (4) is by exhaust tube and air sampling bag (3)
Connect.
As preferably, in described drill bit, it is provided with balancing weight.
As preferably, between described airway (2) and air sampling bag (3), it is provided with valve.
Compared with the prior art, this utility model has the advantage that tubular body is separated by this utility model
Being four independent regions, an injection, four differing heights are separately sampled, can reduce different depth collection
Artificial disturbance to soil during soil gas sample, improves the accuracy of sample collecting.
Accompanying drawing explanation

Including in cylindrical body and the drill bit of cone, described tubular body is by the orthogonal longitudinally partition of two panels
Sheet average mark is divided into four regions, and described four regions respectively set an air inlet 5, and pipe is located at by described air inlet 5
On the tube wall of body, described four air inlets 5 are respectively in different vertical heights, in described air inlet 5
Being provided with filter, described filter can isolate the water in soil, and the top of described body sets circular cover, institute
Stating cover plate and be provided with four ventholes, described four ventholes correspond respectively to four overlying regions, described four
Respectively setting an airway 2 in venthole, described airway 2 one end enters intra-zone, and the other end stretches into air
Sampler bag 3, described air pump 4 is connected with air sampling bag 3 by exhaust tube.
During use, sampler 1 injection is needed the soil of sampling, treats that gas passes through air inlet 5 and slowly enters
Four regions of sampler 1.Open air pump, by four air sampling bag 3 vacuum state, open
Valve on airway 2, the gaseous sample in four regions of extracting sampler 1 is to corresponding air sampling respectively
Bag 3, carries out labelling, completes sampling.
Understand as shown in Figure 2, in described drill bit, be provided with balancing weight.
Understand as shown in Figure 1, between described airway 2 and air sampling bag 3, be provided with valve.
The above, only this utility model preferably detailed description of the invention, but protection model of the present utility model
Enclose and be not limited thereto, the technology model that any those familiar with the art discloses at this utility model
In enclosing, the change that can readily occur in or replacement, all should contain in protection domain of the present utility model.Therefore,
Protection domain of the present utility model should be as the criterion with the protection domain of claims.
