Description
Technical field
The utility model relates to a kind of geotechnical engineering detection device, especially a kind of underwater sediment(s) infiltration coefficient is quickly surveyed
Determine device.
Background technique
Coefficient of permeability K is also known as hydraulic conductivity, is the important hydrogeological parameter for describing medium osmosis ability.It is not of the same race
The deposit of class, K value difference be not very big.Therefore, accurately the infiltration coefficient of measurement deposit is a highly important job.
Currently, existing osmotic coefficient investigating vertical tube device uses the test tube of a fixed bore, according to interval time
The change of water level of test tube finds out deposit coefficient of permeability K；Conventional infiltration test can not be carried out near water and under water, existing vertical tube dress
It is lower to set test efficiency, it is particularly evident especially for the lesser deposit of infiltration coefficient, and there are the same of deviation for artificial reading
When to consume a large amount of manpowers.
Utility model content
In order to overcome the shortcomings of that existing osmotic coefficient investigating device, the utility model provide a kind of underwater sediment(s) infiltration
Coefficient rapid determination device.
Technical solution adopted by the utility model to solve its technical problems is：Underwater sediment(s) infiltration coefficient quickly measures
Device, including, upper vertical tube, adapter flange, lower vertical tube and water-level probe, the diameter of the lower vertical tube are greater than upper vertical tube, upper perpendicular
Pipe connects lower vertical tube by adapter flange, is equipped with leak-proof gasket in adapter flange, the water-level probe is set in upper vertical tube pipe
Bottom.
The lower vertical tube is one kind of straight tube or bend pipe shape.
It is probeed into underwater deposit under lower vertical tube, the water-level probe 4 in guarantee in vertical tube is below the water level of underground water；
Water-level probe can find out deposit infiltration system in conjunction with Darcy's law by the 1 head changes in flow rate of upper vertical tube of measurement small diameter tube
Number K；It solves and is tested using the conventional vertical tube with bore, the drawbacks of taking time and effort, while substantially increasing test accuracy.
The utility model has an advantageous effect in that：Using the variable diameter design of upper vertical tube and lower vertical tube, due to water-level probe
The instantaneous flow that deposit flows out in interval time t=t2-t1, the t time is equal to upper horizontal and flows into the instantaneous of deposit
Flow is declined by the head of the measurement record lesser upper vertical tube of caliber, can find out deposit infiltration system in conjunction with Darcy's law
Number K；Solves the drawbacks of conventional infiltration test can not be carried out near water and under water；It is arranged in pairs or groups according to upper vertical tube different tube diameters, it can be effective
Improve field test efficiency；Water-level probe automatic measurement simultaneously records head in upper vertical tube, greatly improves test data accuracy, contracts
Short test period；Lower vertical tube uses straight tube or bend pipe shape, gos deep into deposit using horizontal or vertical direction under water, can be real
Now measure vertical, horizontal-hole blasting；With preferable practical value.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the utility model implementation diagram.
Components and number in figure：
The upper vertical tube of 1-；2- adapter flange；Vertical tube under 3-；4- water-level probe.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in Figure 1, technical solution adopted by the utility model to solve its technical problems is：Underwater sediment(s) infiltration system
Number rapid determination device, including, upper vertical tube 1, adapter flange 2, lower vertical tube 3 and water-level probe 4, the diameter of the lower vertical tube 3
Greater than upper vertical tube 1, upper vertical tube 1 connects lower vertical tube 3 by adapter flange 2, is equipped with leak-proof gasket, the water in adapter flange 2
Position probe 4 is set to the bottom in upper 1 pipe of vertical tube.
The lower vertical tube 3 is one kind of straight tube or bend pipe shape.
Implementation process：
As shown in Figure 1, the specification that upper 1 diameter of vertical tube is suitable according to the collocation of different sediment types；When test, first measurement examination
Soil testing segment length L and groundwater level H0 is tested, is probeed into underwater deposit under lower vertical tube 3, and guarantees the water in upper vertical tube 1
Position probe 4 is below the water level of underground water；Interval time t=t2-t1,4 automatic measurement of water-level probe simultaneously record upper 1 water of vertical tube
Head, it is respectively H2, H1 that upper vertical tube 1, which manages interior head, since the instantaneous flow of 3 deposit of vertical tube outflow lower within the t time is equal to
Upper vertical tube 1 manages the interior instantaneous flow for flowing into deposit, can find out deposit coefficient of permeability K in conjunction with Darcy's law.
Water-level probe 4 is converted by measuring and recording head in the lesser upper vertical tube 1 of caliber, finds out deposit infiltration coefficient
K greatly improves test data accuracy, shortens test period.
The different mounting means of lower vertical tube 3 can measure the infiltration coefficient of deposit different directions, as shown in Figure 1, lower vertical tube 3
Vertical insertion deposit can measure deposit vertical hydraulic conductivity Kv。
When measuring deposit horizontal-hole blasting, as shown in Fig. 2, lower vertical tube 3 is bend pipe shape, lower vertical tube 3 is horizontal under water
Go deep into deposit to horizontal direction, deposit horizontal-hole blasting K can be measuredh。
Finally it should be noted that：Above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, those skilled in the art should understand that：
It is still possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is carried out etc.
With replacement；And these are modified or replaceed, various embodiments of the utility model technology that it does not separate the essence of the corresponding technical solution
The spirit and scope of scheme.
