Description
Technical field
The utility model is related to a kind of device that loose sandy soil saturated hydraulic conductivity is measured based on core cutter method.
Background technology
At present, it is necessary to which the cutting ring after immersion is removed in the experimentation that saturated hydraulic conductivity in soil is measured using core cutter method
Cutting ring, is then put on glass or plastic funnel by lid and filter paper, determines the soil hydraulic conductivity under fix-head height, then root
According to darcy (Darcy.H) formula of porous media under saturation state, soil infiltration coefficient is calculated, including just oozes coefficient and steady ooze and is
Number.There is problems with the experiment, first, if cutting ring is placed directly on funnel, due in cutting ring soil be in completely satisfy
And state, if experiment soil is loose porous sand, soil is easy to the avalanche under head pressure, so that along funnel
Flow directly into the beaker of lower section, once there is the native phenomenon of leakage to occur, test data is then without reference to value, if avalanche occurs for soil
Phenomenon, it is necessary to resurvey pedotheque, takes a lot of work laborious, and effect is not good.Secondly, if putting filter in the middle of cutting ring and funnel
Paper, filter paper may rupture because of long-time immersion in addition top cutting ring sharp edges, so that part current are flowed into by funnel
Transfer the measurement apparatus such as beaker so that the water that can not be spilt in the Accurate Determining unit interval.It is of the prior art to be based on cutting ring
The device of method measurement saturated hydraulic conductivity in soil replaces filter paper using hard screen pack, and cutting ring is directly installed on screen pack,
Screen pack is directly installed on funnel, cutting ring and filter screen, is all existed between filter screen and funnel without any fixing device because of cutting ring
Installation can not be consolidated and filter screen can not be closely connected with funnel so as to the problem of influenceing experiment effect.
The content of the invention
The purpose of this utility model is to solve cutting ring in the existing device that saturated hydraulic conductivity in soil is measured based on core cutter method
Installing unsteady technical problem with gauze, there is provided a kind of dress that loose sandy soil saturated hydraulic conductivity is measured based on core cutter method
Put.
The technical scheme that the utility model is used by solution its technical problem is：One kind measures loose sand based on core cutter method
The device of matter saturated hydraulic conductivity in soil, including cutting ring, circular hard gauze and funnel, the circular hard gauze are mounted in funnel
On, the circular hard yarn is on the net provided with the hard annulus matched with cutting ring, and the edge of hard annulus is convex provided with a loop
Platform, cutting ring is arranged in the boss of hard annulus, and the circular hard yarn is off the net to be provided with rubber circle, and rubber circle and inner wall of hopper are tight
Contiguity is touched.
Further, the boss height of the hard annulus is 1cm.
Further, the mesh number of the circular hard gauze is 600 mesh.
The utility model is respectively equipped with hard annulus and rubber circle with boss in the top and bottom of circular hard gauze, with convex
It is online that the hard annulus of platform makes cutting ring be stably mounted at circular hard yarn, it is ensured that the pedotheque of collection and circular hard gauze
Be in close contact, prevent caving in and mobile for pedotheque, rubber circle is close on the inside of funnel, by during certain pressure by gauze with
Funnel junction is closely connected, and prevents that soil flows into lower section with water in cutting ring；And after a soil sample has been determined, can remove rapidly
Fall top cutting ring, circular hard gauze is taken out and is rinsed rapidly, can be used to determine next pedotheque in the short time.
Therefore, compared with background technology, the utility model have can anti-soil avalanche, water penetration steadiness is good, easy to be easily operated, makes
Valency is cheap, and operating efficiency is high, advantage easy to utilize.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of the circular hard gauze of the utility model and hard annulus.
Embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2, a kind of in the present embodiment measures loose sandy soil saturated hydraulic conductivity based on core cutter method
Device, including cutting ring 1, circular hard gauze 2 and funnel 3, the circular hard gauze 2 is on funnel 3, circular hard gauze
2 mesh number is 600 mesh, and the circular hard gauze 2 is provided with the hard annulus 4 matched with cutting ring 1, the side of hard annulus 4
Edge is provided with a loop boss 6, and cutting ring 1 is arranged in the boss of hard annulus 4, it is ensured that cutting ring 1 can stablize not inclined peace
Loaded on gauze 2, the boss height of the hard annulus 4 is 1cm.The circular hard gauze 2 has rubber circle 5, rubber
Circle 5 is in close contact with inner wall of hopper.
In the present embodiment, rubber circle 5 is fixed on to the bottom of circular hard gauze 2 with strong adhesive, to ensure circle
Shape hard gauze 2 is closely connected with lower end funnel 3, and the hard annulus 3 is made up of hard materials such as hard PVCs, described
Rubber circle 5 is vulcanization rubber, and the circular hard gauze 2 is made up of the nylon material of 600 mesh, can also use metal or synthesis
Other hard materials such as fiber are replaced.Replaced placing filter paper in current determination techniques or not letting alone with circular hard gauze 2 how blocking
The mode of parting, mainly for loose porous sandy soil, it is to avoid human factor is to experimental rig and the shadow of result of the test
Ring, and after a soil sample has been determined, top cutting ring 1 can be removed rapidly, circular hard gauze 2 is taken out and is rinsed rapidly,
It can be used to determine next pedotheque in short time, and the equipment can reach and prevent loose sand from leaking down very with water
To the purpose of avalanche, water penetration steadiness is good, it is ensured that quality of experiments, easy to be easily operated.
