Description
Technical field
The utility model belongs to dredging Geotechnical Engineering field, collapses more particularly to one kind for measuring dredging clay ball
Solve the test device of experiment.
Background technique
In dredging work, be often mixed with sand in underwater clay, the molecular force and electrical force on sand surface increase itself and clay it
Between cohesive force；Since cutting speed is fast when reamer ship is constructed, pumping pressure is limited, is easy to form clay ball in the duct, cause
Pipeline plugging influences construction speed and causes economic loss.Therefore, by disintegration rate of the measurement clay ball in hydrostatic, collapse
Xie Liang, disintegration time and disintegration feature can reduce the probability of clay balling-up to change ship construction technology, increase shape
At clay ball disintegration rate, pipeline plugging is avoided.
The characteristic that spallation occurs to be disintegrated because of immersion for soil is known as native disintegration；It is led in agricultural meteorology and geotechnical engineering
Domain, soil disintegration are also called soil humidifying, are that dispersion, calving, fragmentation disintegration, slump or intensity occur in hydrostatic for a kind of soil
The phenomenon that decrease, and a kind of important soil physical index of evaluation soil erosion severity.After soil body immersion, water access aperture
Gap or crack, thicken so as to cause moisture film between soil particle and the original air compression of hole, moisture film thicken speed difference and sky
Air pressure contracting escape causes repulsion between soil particle to be more than suction, generates stress and concentrates, and making the soil body is more than the maximum of suction along repulsion
Face avalanche is got off.
From the sixties in last century, Zhu Xianmo is just proposed using soil property disintegration situation characterization soil erodibility in hydrostatic.90
Mid-nineties 90, Jiang Dingsheng etc. measure loess disintegration rate using self-control float-type Simple soil disintegration tester.In the prior art, practical
New patent 200720082661.9 proposes a kind of soil disintegration determinator, including sink, soil sample suspension, and it is flat that sink is placed in lifting
On platform, soil sample suspension is suspended on electronics hydrostatic balance and is located above sink.The invention is equaled a record soil using electronics hydrostatic day
Sample weight change improves reading accuracy.201110356496.2 patent of invention, propose a kind of test of soil disintegration
Instrument is made of scale, blister, lead button, hanging box, sieve, glass container with a scale and earth sample.By scale, blister and mark
Ruler connects the buoyant device to be formed and is placed in glass container with a scale, and scale lower end is connect with blister upper end, and hanging box ties up to mark
The junction of ruler and blister, blister are placed in hanging box, and blister is provided with lead button, and hanging box bottom is furnished with sieve, places soil on sieve
Sample；The invention is dipped in earth sample in liquid by buoyant device, when earth sample starts disintegration, due to the reduction of gravity, floats
Power device moves upwards, the displacement that can be floated according to the scale judgement of scale above buoyant device, so that it is determined that disintegration amount.
But in dredging work field, nothing is applicable in the device that measurement strand suction hydraulic reclamation goes out clay ball disintegration rate at present.Also,
Also have segmental defect in above-mentioned patent: graduated scale, scale, which enter, to be not easy to correct in water；It needs using high-density matters such as lead buttons
As blister, the epidemic situation comparison for reaching more stable is difficult；Electronic balance uses limited time；Disintegration experiment for a long time has ignored outer
Portion's environment influences water；The influence etc. of soil moisture content and buoyancy to disintegration amount is not accounted for.It is disintegrated compared to general soil
Experiment, clay ball change in size is big, has from 5cm-25cm；Clay ball solution form be it is diversified, have uniform shot shape, squama
Sheet, fragment shape etc.；Clay ball moisture content difference leads to the disintegration amount of soil property and the difference of disintegration rate；Form clay ball
Grain diameter changes the difference for also leading to clay ball disintegration amount.
