Utility model content
The utility model, in order to solve the problem, provides one simply handy, cheaply efficiently, and the strand tidal flat undisturbed soil post sample sampler that cost is low.
In order to solve the problems of the technologies described above, adopt following technical scheme: first plexiglas pipe or the polishing of pvc pipe one end outer wall are fined away, plexiglas pipe or pvc pipe are cut down end along polishing and squeezes into soil, then the sealed bag of sealing is enclosed within the suitable for reading of plexiglas pipe or pvc pipe, discharge the air between pedotheque top layer in sealed bag and pipe, then by sealed bag and to be suitable for readingly tightly connected, then plexiglas pipe or pvc pipe are taken out from soil, finally by plexiglas pipe or the sealing of pvc pipe two ends.
Preferably, described step 2 is at plexiglas pipe or pvc pipe pad suitable for reading one piece of plank, knocks plank, thus plexiglas pipe or pvc pipe are squeezed into soil along polishing reduction end.
Preferably, the width of described plank is no more than the diameter of plexiglas pipe or pvc pipe mouth.
Preferably, the step of discharging the air in sealed bag and pipe between pedotheque top layer described in step 3 be with the object of the diameter being less than plexiglas pipe or pvc pipe mouth by sealed bag from plexiglas pipe or pvc pipe suitable for reading disclose into, until to pedotheque top layer in pipe.
Preferably, described in step 3 by sealed bag and the step be tightly connected suitable for reading for sealed bag is entangled in plexiglas pipe or pvc pipe outer wall with adhesive tape.
Preferably, described step 4 is be wound around plexiglas pipe or pvc pipe outer wall with manila rope, thus plexiglas pipe or pvc pipe is taken out from soil.
Preferably, be with sealed bag or with the pipe lid supporting with pvc pipe footpath, pipe two ends are sealed the step that plexiglas pipe or pvc pipe two ends seal described in step 5.
Preferably, the internal diameter of described plexiglas pipe or pvc pipe is 75-100mm, and length is 60-120cm.
The utility model provides a kind of strand tidal flat undisturbed soil post sample sampler, comprise be made up of plexiglas pipe or pvc pipe cylindrical shell, sealing sealed bag and can be used for sealing the seal of nozzle, described cylindrical shell one end has beveled tip, and described sealed bag can be enclosed within cylindrical shell.
Preferably, described cylindrical shell is internal diameter is 75-100mm, and length is 60-120cm, and described seal is the sealed bag of sealing or the pipe lid supporting with cylindrical shell caliber.
Compared to the method using the sampling of half opening stainless steel sampler, use the method for plexiglas pipe and pvc pipe sampling simply handy, cheaply efficiently, cost is low.Plexiglas pipe and pvc pipe are off-the-shelf, and price, well below needing to make half opening the stainless steel sampler, particularly pvc pipe of special Making mold and supporting pipe cap, can have been bought easily in the hard ware store of routine.Because pedotheque is sealed in plexiglas pipe or pvc pipe, can keep for a long time being undisturbed state, and the post sample that is undisturbed that plexiglas pipe and pvc pipe obtain can be carried out freezen protective, thus in the research such as microorganism and environmental geochemistry.Plexiglas pipe and pvc pipe are tubular structure, increase the contact area of soil and tube wall, thus obtain larger friction force, and the air of discharging in sealed bag and pipe between pedotheque top layer, and by sealed bag and to be suitable for readingly tightly connected, at this moment do not have air to enter sealed bag, the soil top in sealed bag and pipe is close to vacuum.Because pipe top air pressure is much smaller than external atmosphere pressure, pedotheque can remain in pipe under external atmospheric pressure, even if pipe is drawn out ground.
