Description

A kind of SOIL GAS sampling hole device

Technical field

The utility model is related to dig the device of boring in a kind of sampling process for SOIL GAS, belongs to field of environment protection In Environment features apparatus field.

Background technology

With China to the issue of the attention of environmental protection industry (epi) and " Soil Pollution Control action plan " and auxiliary work Carry out, contaminated soil monitoring and relevant device initially enter the booming stage.For China in a large number due to " move back two and enter three ", work Pulling down and removing a building for reconstruction the industrial pollution place left in industry garden, especially there is volatility or semi-volatile organic matter in land used history (vocs/svocs) plot polluted, in addition to traditional soil, underground aqueous medium are detected, the detection of SOIL GAS becomes An indispensable important ring during site investigation, reparation and monitoring.

SOIL GAS sampling hole can share a well with common soil sample or underground water water sample acquisition mode, traditional shaft building Mode is common to be had: digs boring using equipment such as percussive drill, direct push technology, twist bits.With soil, underground water Detection is different, there are following features in SOIL GAS detection: one be SOIL GAS testing goal be to measure vocs/ in soil media The gaseous component concentration of svocs, normally only detects, soil is as a kind of its gas of porous media to 0～2 meter of depth under earth's surface Bulk diffusive characteristics have both determined too deep SOIL GAS detection well unnecessarily, also meaningless；Two is that SOIL GAS is subject to after boring is formed External environmental condition impact is the most substantially it is desirable to sampler's laying gas collection device action is rapid；Three is single soil gas drilling hole Aperture is often little than soil sample well, water sample well.If these factors are determined SOIL GAS drilling well and are deposited using traditional method of well construction In the low problem of uneconomical, efficiency.

Content of the invention

The invention provides a kind of manpower of depending merely on quickly can dig setting of SOIL GAS sampled well in no cement hardened ground Standby.This device structure is simple and easy and simple to handle, the operating efficiency of SOIL GAS sampling can be greatly improved, have very high promotion price Value.

In order to realize foregoing invention purpose, the technical scheme that the utility model is adopted is as follows:

A kind of SOIL GAS sampling hole device, comprising: bottom bar, taper head, the collar, extension rod and sliding hammer；Under described bottom bar End is fixed with removable taper head, and upper end carries internal thread, and the collar is fixed on bottom bar；Extension rod lower end pass through external screw thread with The internal thread of bottom bar upper end connects, and upper end has the internal thread being connected with other extension rod lower ends；Sliding hammer is with handles and middle Open the structure of through hole, insertion bore dia is slightly larger than the diameter of extension rod and bottom bar.

The fixing taper head in bottom bar lower end, has the selective of different cone angle structure；Sliding hammer has the selective of Different Weight, prolongs Stock can multiple be sequentially connected.

Scale is all had on bottom bar and extension rod.

A kind of SOIL GAS sampling hole device described in the utility model, its advantage is: one is a simplified soil Gas sampling shaft building process, greatly shortens shaft building required time, improves the speed laying gaseous sample collection bag；Two is this Device compares common shaft building machinery, and pure manpower drives, and place need not be required to have power supply or power-equipment；Three is device structure letter Single, easy and simple to handle, one just can realize SOIL GAS shaft building sampling, is conducive to large-scale promotion SOIL GAS Sampling techniques.

Brief description

Fig. 1 is the structural representation of extension rod of the present utility model, bottom bar and the collar.

Fig. 2 is the structural representation of sliding hammer of the present utility model.

In figure is numbered: 1, extension rod, and 2, the collar, 3, bottom bar, 4, taper head, 5, sliding hammer.

Specific embodiment

Concrete structure of the present utility model referring to Fig. 1,2.A kind of SOIL GAS sampling hole device, comprising: with internal thread Bottom bar 3, the taper head 4 on bottom bar, the collar 2, carry female extension rod 1 and sliding hammer 5；Described bottom bar 3 lower end is fixed with Removable taper head 4, upper end carries internal thread, and the collar 4 is fixed on bottom bar 3；External screw thread and bottom bar are passed through in extension rod 1 lower end The internal thread of 3 upper ends connects, and upper end has the internal thread being connected with other extension rod lower ends；Sliding hammer 5 is with handles and centre is opened The structure of through hole, insertion bore dia is slightly larger than the diameter of extension rod 1 and bottom bar 3.The fixing taper head in bottom bar lower end, has difference Cone angle structure selective；Sliding hammer has the selective of Different Weight, and extension rod can multiple be sequentially connected.On bottom bar and extension rod all There is scale.

Taking gather SOIL GAS at lower 1.5 meters of certain hard surface as a example.First the internal thread bottom bar 3 with the collar 2 is changed The minimum taper head 4 of cone angle, and plus a female extension rod 1 of band, tighten each part.Adopt weight maximum simultaneously Sliding hammer 5.Lift sliding hammer and allow sliding hammer freely to fall along extension rod 1 to pound on the collar 2.This process produces impacts and to break road surface hard Change layer.

After breaking road surface hardened layer, use cone angle less taper head 4 instead, and continue to pound downwards to indicated depth, from bar Upper reading deep calibration simultaneously keeps a record.So operation then completes a SOIL GAS sampled well.

It should be evident that the accompanying drawing in foregoing description and explanation are only embodiment of the present utility model, for this area For those of ordinary skill, on the premise of not paying creative work, the product after being modified according to the present invention must regard It is within this patent protection domain.
