Description
Technical field
The present invention relates to a kind of saturated hydraulic conductivity in soil measuring device more particularly to it is a kind of measurement saturated hydraulic conductivity it is simple
Device.
Background technique
Core cutter method measurement saturated hydraulic conductivity in soil (infiltration coefficient) used at present needs in its operating procedure pre-
The interior cutting ring by after immersion for 24 hours of fixing time removes lid, in, two cutting ring connections, with all scholar placed on it with an idle loop knife
Woods smears interface, is clung with transparent adhesive tape, then on idle loop knife above plus water, head height lead idle loop knife inner wall fortunately
It marks.But the test method, test measurement person in the actual operation process, can encounter some problems:
1, interface smears vaseline water appears in order to prevent, but smearing degree etc. is without accuracy, may be at some
Point holiday, or applied and be stained in cutting ring in soil sample, it can all cause resultant error；
2, after interface is sealed with transparent adhesive tape, meeting is not smooth enough since transparent gluing obtain gap, and adhesive plaster has centainly
Extensibility, often extension space can be left in interface to a certain degree after stress, so that can not be by two cutting rings in experimental period
Between combine closely always.
3, it is inconvenient and inaccurate to overlook reading head height by measuring person.And it needs according to each one experience either
No leak verifying, once there is drainage, it is necessary to smear vaseline again, then use scotch-tape again, take a lot of work laborious.
Summary of the invention
The object of the present invention is to provide a kind of easy devices for measuring saturated hydraulic conductivity.
The purpose of the present invention is what is be achieved through the following technical solutions:
The easy device of measurement saturated hydraulic conductivity of the invention, including graduated glass and rubber ring, the graduated glass include upper
Cup body and fixed ring are carved with scale in the upper cup body, and the upper cup body is arranged above and below with cutting ring, described in the fixed ring compresses
Rubber ring, and the rubber ring is pressed on the seam areas of the upper cup body and cutting ring.
As seen from the above technical solution provided by the invention, measurement saturated hydraulic conductivity provided in an embodiment of the present invention
Easy device, structure is simple, and effect is obvious, and so as to facilitate test, convenient for operation, and sealing effect is good, can be significantly
Raising working efficiency.

Specific embodiment
The embodiment of the present invention will be described in further detail below.What is be not described in detail in the embodiment of the present invention is interior
Appearance belongs to the prior art well known to professional and technical personnel in the field.
The easy device of measurement saturated hydraulic conductivity of the invention, preferable specific embodiment is:
Including graduated glass and rubber ring, the graduated glass includes upper cup body and fixed ring, is carved with scale in the upper cup body,
The upper cup body is arranged above and below with cutting ring, and the fixed ring compresses the rubber ring, and the rubber ring is pressed on the upper cup
The seam areas of body and cutting ring.
The upper cup body and fixed ring are linked together by connecting portion.
The interface position of the fixed ring is fastened with bolt and nut.
The upper cup body diameter is equal with cutting ring diameter, and the internal diameter of the fixed ring is greater than the cutting ring outer diameter, described solid
Determining ring has the gap 4mm at interface position.
The upper cup body material is polypropylene plastics.
The present invention measures the easy device of saturated hydraulic conductivity, and structure is simple, and effect is obvious, so as to facilitate test, just
In operation, and sealing effect is good, can greatly improve working efficiency.
In the present invention, cup body is equal with cutting ring diameter on the graduated glass, and material is polypropylene plastics, is carved on cup
Degree, instead of the superposed idle loop knife of conventional apparatus, facilitates head to read, unit cm, and cup body and cutting ring are arranged up and down on graduated glass
Column, by the way that fixed ring is compressed rubber ring, rubber ring compress cup body and cutting ring on graduated glass reach on fixed graduated glass cup body with
The effect of cutting ring.
The rubber ring is located at the inside of the fixed ring of graduated glass, the fixed ring internal diameter phase of rubber ring outer diameter and graduated glass
Together, rubber ring is contacted with cup body on lower cutting ring and graduated glass when experiment.
The upper cup body and cutting ring of the graduated glass are in close contact blending bolt in rubber ring position and tighten, the bolt and spiral shell
Mother is all made of national standard.
The diameter of the fixed ring of the graduated glass is bigger compared with cutting ring diameter, and to the position of rubber ring, there are spaces.Furthermore solid
Ring is determined in nut location not exclusively at a circumference, and has the gap 4mm, by the cooperation of fastening bolt and nut so that material is sent out
Raw plastic deformation, reaches rubber ring being pressed in cutting ring in the junction of cup body, play the role of sealing.
The invention patent has the beneficial effect that
The present invention is as a kind of efficient easy device of survey saturated hydraulic conductivity, instead of smearing vaseline in the prior art and gluing
The mode for pasting transparent adhesive tape, avoids the influence of human factor and device to experimental rig and test result itself, and takes bolt
The method tightened is conceived to cutting ring connection place, is in close contact water-impervious by rubber ring.And the present apparatus does not need two cutting rings
It works, upper cup body indicates scale itself is a device identical with cutting ring diameter, is more convenient direct head reading.
In addition, after a soil sample has been surveyed, it is only necessary to unscrew bolt, next pedotheque can be measured in the short time, significantly
Improve efficiency.
Specific embodiment:
As shown in Figures 1 to 5, including the graduated glass 1 with fixed ring, rubber ring 5, pass through spiral shell between graduated glass 1 and cutting ring 4
Bolt 2 and nut 3 are fixed, and the upper cup body 6 of graduated glass 1 is identical as the inner and outer diameter of cutting ring 4.The device will pass through in usually testing
Upper cutting ring become graduated glass 1, preferably head is facilitated to read, and add a fixed ring, can be by upper cup body and cutting ring more
Good fixation, instead of the mode fixed in the prior art with transparent adhesive tape and vaseline, avoid human factor to experimental rig and
The influence of test result, and it is conceived to the interface of 4 leak of cutting ring, using bolt and nut device, so that cutting ring 4 and graduated glass 1
Upper cup body can rubber ring effect under combine closely, prevent leak, at the same in the detection process can stablize keep this shape
State；And after a soil sample has been surveyed, it is only necessary to unscrew bolt 2, graduated glass 1 is reusable, can survey in the short time
Fixed next pedotheque, greatly improves efficiency.
Other business includes that the width of rubber ring half is located at the upper cup body of graduated glass 1, the other half width is located at 4 rubber of cutting ring
Rubber ring, and the outer diameter of cup body and cutting ring 4 is identical as rubber ring internal diameter, so that cutting ring 4 is easier to contact securely with cup body.
Preferably, bolt 2 and nut 3 take national standard turret head M3 type bolt and turret head M3 type nut.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Within the technical scope of the present disclosure, any changes or substitutions that can be easily thought of by anyone skilled in the art,
It should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with the protection model of claims
Subject to enclosing.
