Description
Technical field
The utility model relates to field of measuring techniques, and in particular to a kind of spring bed mud densitometer measuring device.
Background technique
Currently, the dredging dredging of the river and lake library pool has become the important means of endogenous pollution improvement.Firstly, needing before dredging to silt
Mud thickness is surveyed, to determine dredging sediment and workload；In addition, need to be detected in the region of completion clear during dredging
It becomes silted up and realizes depth, avoid the occurrence of the case where leakage is clear or dredging depth is unsatisfactory for design requirement.
Bed mud is often referred to river and lake library pool bottom recent sediment, the bed mud density value for considering to remove general at present 1.08~
1.8g/cm3In range, density value 1.08,1.2,1.5,1.8g/cm3Bed mud mud, mud and need to be dredged respectively as mud scum, stream
Dredge the Lower Limits of muck soil.Bed mud exploration achievement usually requires that: 1) drawing the deep distributions such as mud scum, stream mud, mud, muck soil
Figure；2) the bed muds siltation volumes such as mud scum, stream mud, mud, muck soil are counted respectively.
Large-scale river and lake fine sediment of reservoir exploration combines drill hole sampling method, Cone Penetration Test, survey frequently with Silas technological system etc.
Bar method carries out；The exploration of brooks and small lakes library pool bed mud and general grass-roots unit, measuring staff method measurement mud depth are also generally made
With；During Dredging Construction, testing staff often uses measuring staff method to detect different parts dredging depth.
Various exploration means features: 1) boating type Silas system has time-saving and efficiency and acquisition information faces feature, simultaneously
Need survey area have certain depth of water, area guarantee, while and vulnerable to water-bed sundries interfere it is stronger, configuration densimeter be directed to
Slurry measurement is more applicable in, is accurate, to density >=1.5g/cm3Mud and muck soil adaptability are poor, or even cannot fit
With；2) drill hole sampling method feature is single-point acquiring column bed mud sample, and the natural density of core cutter method measurement stratified substrate sludge is simultaneously true with this
The thickness of fixed each layering mud, can obtain quantizating index.But drill hole sampling is poor for mud scum and stream mud applicability, becomes silted up under
Mud has certain disturbance, in addition heavy workload, and low efficiency is expensive；3) Cone Penetration Test is carried out using dedicated quiet spy equipment,
Its principle is the bearing capacity that mud is calculated the specific penetration resistance of measuring staff by single point assay mud, so that it is determined that mud is thick
Degree, but operation at sea auxiliary facility is not popularized still, and measurement mud scum, stream mud are poor for applicability；4) measuring staff method is that professional survey crew will
Dedicated measuring staff underthrust perceived by the resistance that meets with to different depth, and survey crew judges the different type bed mud touched
Layer depth calculates each thickness value.The measurement of measuring staff method is simple and easy to do, but precision is affected by many factors, and there has been no quantitatively determine at present
The ability of mud absolute density for mud scum and flows the poor for applicability of mud.
Measuring staff method principle is the thickness read twice using measuring staff to determine different layers bed mud, i.e. measuring staff touches muck surface
When read a depth value, then measuring staff is pushed, when reaching certain resistance, survey crew judges that measuring staff bottom end has been touched
And mud lower surface when read a depth value again, the difference of two depth values is category bed mud thickness.Use such side
When method measures, shape, the size of measuring staff, the size for the power that measuring staff is born directly influence the precision of measurement.
Measuring staff method generallys use the thickness that double measuring staffs read exploration mud respectively at present.A piece lower end is configured with punching chassis
Measuring staff (hereinafter referred to as " I measuring staff "), chassis diameter frequently with measuring staff diameter 50 times (thering is place to be defined as Ф 20cm iron plate),
It is put down gently when measurement into water, measures bed level of the river (i.e. sediment layer crest level)；Then, use instead lower end be unworthy of bottom set disk measuring staff (with
It is known as " II measuring staff " down) it firmly pushes and measures mud bottom elevation, the difference of double measurement is considered as the thickness of mud.
At present common measuring staff method equipment there are the shortcomings that:
It is the most economical although measuring staff method is simple and efficient, and do not interfered substantially by underwater obstacle, measuring staff method application at present is still
It is relatively broad, but measuring staff method detect when can not the First Astronautic Research Institute for Measurement and Test pass through sediment layer density；Determining bed mud bottom elevation, often by detecting
Personnel empirically judge that II measuring staff has touched the lower surface of bed mud, read a depth value and convert, to calculate
Silt depth.Measuring staff method measurement bed mud thickness data is affected by human factors larger, measuring staff institute when especially surveying mud bottom
The size for the lower pressure born directly influences the precision of measurement, while measuring staff method can not determine bed mud in measurement process at present
Absolute density.
