Embodiment one: the in-situ acquisition of heavily contaminated river course deep layer column shaped deposit
Heavily contaminated river drift is one of important sources causing water pollution, and marine sediments are to benthon
Toxic effect especially pronounced, partial contamination river course has not had any biological growth sign, even includes higher plant, therefore
Be badly in need of marine sediments being administered or repairing, and administer with the premise repaired be accurately recognize deposit contamination characteristics and
The deposit depth of pollution layer.To this end, research group loiters river marine sediments as object of study with Yantai, use apparatus of the present invention
This river drift is carried out deep layer in-situ acquisition, thus has fully realized sediment pollution degree, to realize controlling of deposit
Reason and reparation.Concrete operations are as follows:
The first step, standby (see accompanying drawing 1 and accompanying drawing 2) each assembly of sampling cartridge gathered by deep layer column shaped deposit is connected with each other,
Connect external power supply (voltage is 220/380V, commercially available electromotor) by distribution box 7 and receiver of remote-control sytem, open screw thread rustless steel
Seal nipple 17, loads in hollow drill pipe 13 internal by PVC or other material sampling tubes, screws screw thread rustless steel seal nipple
17.Use steel wire rope to fasten knot respectively and promote each snap close of snap close 4, and be connected to crawler type liter after the assembly of all cord ends
On the suspension hook of fall machine, and when ensureing to hang, bearing chassis 5 is substantially at level；
Second step, moves on to the river course predetermined sample area of central heavy Polluted area with crawler-type lifting machine by standby for sampling cartridge, logical
Cross a hoist engine 8 and load bracket 1 top half (heeling condition) is adjusted to plumbness by inclination link 3, pass through remote control
Probing is driven motor 11 to migrate downwards to screw thread rustless steel seal nipple 14 and arrives by device No. two hoist engines 8 of operation and slide rail 2
Till deposit surface.Open probing and drive motor 11 so that probing rotary blade 12 is drilled downward vertically.Reach predetermined sampling
After the degree of depth, drive motor 11 to be inverted by probing rotary blade 12 by remote control unit operation probing, sampling tube will be installed
Hollow drill pipe is left the water；
3rd step, uses crawler-type lifting machine to move on on river levee by whole sampling apparatus, by a hoist engine 8 with incline
Load bracket 1 top half (plumbness) is adjusted to heeling condition, manual unlocking screw thread rustless steel by rake angle adjusting means 3
Seal nipple 17, takes out built-in sampling tube, again screws under screw thread rustless steel seal nipple 17 carries out after more renewing sampling tube
Secondary sampling；
4th step, the sampling tube containing deposit that the 3rd step is changed, require to be layered according to desired depth successively
Cutting, numbering, be then stored in associated sample on-the-spot refrigerator and take back laboratory and carry out the analysis of deposit index of correlation；
5th step, after completing sample input, cut-out distribution box 7 and receiver of remote-control sytem external power supply, disengaging section assembly, clearly
Wash relevant device and transport laboratory back and seal up for safekeeping.
