Description
Technical field
The utility model relates to Dredging Fields, measure sampler more particularly to a kind of underwater mud scum.
Background technique
Water-depth measurement method is broadly divided into two kinds again, i.e. acoustic measurement and water stone roller measurement.In acoustic measurement, high band sound wave
The upper interface of mud scum can be measured, and low-frequency range sound wave can penetrate Mud Layer, measure hardcore, can not accurately measure Mud Layer
Thickness, the corresponding mud scum thickness of especially certain mud scum bulk density.Water stone roller measurement can only generally measure interface under Mud Layer or refer in particular to
The interface of unique mud scum bulk density, what is actually measured due to water stone roller measurement is that water is cut or polish jade with an emery wheel to the rope length between the water surface, due to underwater water
The reason of stream, the rope that water is cut or polish jade with an emery wheel cannot keep plumbness, therefore measurement rope length can have very big error.
The method of underwater acquisition mud sample is broadly divided into two kinds, i.e. the sampling of drilling rod formula and lifting rope sampling.Wherein drilling rod formula samples
What is mainly acquired is the soil layer mud sample under hard, rather than mud scum, and acquisition speed is slow, costly, and sampling operation procedure is complicated；
Sling type sampling can acquire rapidly mud scum, but the corresponding depth of acquisition mud scum can not be measured accurately.

Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, with reference to the accompanying drawing
The utility model is described in further detail with most preferred embodiment.
Fig. 1-2 shows a kind of underwater mud scum measurement sampler, including sampling unit and mud scum measuring unit；Described is floating
Mud measuring unit includes bracket 15, water pressure gauge 17 and is arranged at intervals on from bottom to top more on the bracket vertical direction
16 based on a gross pressure by measuring muddy water gross pressure.Gross pressure meter in the application uses soil pressure cell, and water pressure gauge uses
Pore pressure gauge, wherein pore pressure gauge can be used to sound the depth of the water.The down tube is arranged in the water pressure gauge
Upper end lateral location；Gross pressure meter described in bottom is concordant with the lower end of the down tube, the gross pressure meter of the top
It is concordant with the upper end of the down tube.
The sampling unit includes outer tube 5, the inner tube being arranged in the outer tube 1 and described outer for clamping

Calculate mud scum average volume density between two earth pressure gauges.In this way according to the required precision of real work, different number is arranged
Gross pressure meter, accurately can calculate and draw Mud Layer mud scum bulk density change of gradient figure and corresponding water depth value.Meanwhile it will
Inner tube is arranged to top tube and down tube, after can making sampling, avoids pressure difference.
Clamping piece is set in the upper end of outer tube, when entering water, the lifting rope on annulus is straightened, and makes locked by hooks outer tube, until taking
Sample position, sets that there are two opposite almost can be used for sampling through the rectangular aperture of tube body up and down on the tube wall of down tube, samples
After, lifting rope is loosened, hook release outer tube is made, then outer tube under the action of self-weight entangles the down tube of inner tube, closes interior
The rectangular aperture of pipe, thus mud sample needed for obtaining, and guarantee that mud sample keeps nature, it is not disturbed.Sampling pipe pedestal,
Rubber mat and outer tube lower end setting platen can enable outer tube be discharged on pedestal and reduce vibration.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
