Description
Technical field
The utility model belongs to natural Loessial Joints parameter measurement field, more particularly to a kind of natural Loessial Joints contact surface
Long-pending measurement apparatus.
Background technology
Loessial Joints are the spaces formed after loess is formed by inside and outside stress and neotectonics, are widely present in loess
Highlands, its presence has very important influence to yellow soil characteristics.Joint seepage flow be Canal in Loess Area tunnel, cave dwelling,
The important factor in order of massif, highway slope stability, joint contact area is to influence the key factor of joint seepage flow, therefore is visited
A kind of simple, economic, practical method of rope, which obtains joint contact area, has higher practical significance and construction value.
Natural joint contact area is obtained by combining the joint configuration of surface that two panels is handled through computer at present, to technology
Level has higher requirements, and operation difficulty is big.It is how simple, economic as people deepen continuously to joint Seepage problems research
The natural joint contact area of acquisition loess turn into urgent problem.
Utility model content
The purpose of this utility model is to provide a kind of measurement apparatus of natural Loessial Joints contact area, existing to solve
Technical merit has higher requirements in technology, the problems such as operation difficulty is big.
To achieve the above object, the utility model uses following technical scheme：
A kind of measurement apparatus of natural Loessial Joints contact area, including sealing bucket, inlet duct, porous sample placement platform and
Bung；Bung is arranged on the upper end of sealing bucket, and porous sample placement platform is arranged on the lower section of bung perpendicular to the inwall of sealing bucket；It is close
The sidewall bottom of envelope bucket is provided with air inlet, and inlet duct is connected with air inlet；Gas outlet is provided with bung.
Further, if presetting dry powder in sealing bucket.
Further, powder uses particle diameter in below 0.075mm powder.
Further, sealing bucket uses transparent material.
Further, dust-removal cloth-bag is also associated with gas outlet, gas outlet and dust-removal cloth-bag are connected by connecting tube.
Compared with prior art, the utility model has following technique effect：
Device of the present utility model can make powder be distributed on joint surface, and the system is easy to processing, and material easily takes, have compared with
Good economic benefit, system operation principle is understandable, simple to operate, and desirable preferably spreads effect.
The utility model is by the equal powdering end in joint surface, with reference to image processing techniques, obtaining the contact of Loessial Joints
Area, method is simple, economic, practical property strong, and new approaches are provided for measurement joint contact area.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Wherein：1st, bucket is sealed；2nd, bung；3rd, gas outlet；5th, dust-removal cloth-bag；6th, air inlet；7th, inlet duct；8th, it is porous to put
Sample platform.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated：
Refer to shown in Fig. 1, a kind of measurement apparatus of natural Loessial Joints contact area, including sealing bucket 1, inlet duct
7th, porous sample placement platform 8 and bung 2；Bung 2 is arranged on the upper end of sealing bucket 1, and porous sample placement platform 8 is perpendicular to sealing bucket 1
Inwall is arranged on the lower section of bung 2；The sidewall bottom of sealing bucket 1 is provided with air inlet 6, and inlet duct 7 is connected with air inlet；Bucket
Gas outlet 3 is provided with lid 2.
If presetting dry powder in sealing bucket 1.
Powder uses particle diameter in below 0.075mm powder.Sealing bucket 1 uses transparent material.
Dust-removal cloth-bag 5 is also associated with gas outlet 3, gas outlet 3 and dust-removal cloth-bag 5 are connected by connecting tube.
The measuring method comprises the following steps：
1) a certain amount of powder is placed in sealing bucket 1 bottom, takes out the axle sample of standard three containing natural Loessial Joints, by half
Block sample joint being placed on porous sample placement platform 8 up；
2) start inlet duct 7, powder is kicked up in the presence of inlet duct 7, closed after powder floats are full of sealing bucket 1
Inlet duct 7 is closed, after restarting inlet duct 7 after powder deposition, is repeated the above steps, until joint surface is uniformly sprinkled
Stop during one layer of powder；
3) sample that surface covers powder is taken out, second half sample is placed on thereon with corresponding position, two minutes are stood
After remove, using digital camera shoot joint surface, joint contact part colours can be different from other parts；
4) grid is drawn on picture using image processing software, lattice number shared by surface color different zones and total net
The ratio of lattice number is the contact area at joint and the ratio of the gross area, directly measures the gross area to obtain the contact at joint
Area.
