Description
Technical field
The invention belongs to field of civil engineering, and in particular to a kind of artificial coarse-grained soil forming instrument, can for preparing shaping
Controlled stage is matched somebody with somebody and the artificial coarse-grained soil of granule strength simulates coarse-grained soil.
Background technology
Coarse-grained soil is widely used in the construction of the Geotechnical Engineerings such as water conservancy, harbour, traffic, thus domestic and foreign scholars pair
Coarse-grained soil has carried out substantial amounts of research, but natural stockpile self property is more complicated, is difficult quantitative study, thus uses
Utopian controllable level is matched somebody with somebody and the artificial coarse-grained soil simulation coarse-grained soil of granule strength seems very meaningful.
In the research of common manual simulation's coarse-grained soil, soil particle generally uses glass marble, steel ball or cement ball etc., its
In, the parameter such as elastic modelling quantity, Poisson's ratio of glass marble and steel ball differs larger with natural stockpile, while can not combine needing
Adjustment granule strength, thus can not well simulate the relevant nature of natural coarse-grained soil.At present, manual simulation's coarse-grained soil is more
Using cement ball or ellipsoid, other materials is suitably incorporated by cement paste or cement mortar and is prepared from.Viscosity between cement granules
Difference, cement ball be difficult shaping, prepare it is relatively difficult, and, often demand is than larger.Therefore, prepared by cement ball turns into one
Problem.Such as using manually method is twisted, can be molded, but waste time and energy, it is impossible to meet the demand of experiment.Also have using upper lower half
Ball mould is poured respectively, after upper/lower die is overlapped, formed cement ball.But, the cement ball globality poor of this method preparation,
Interposer contact portion combine loosely, to prepare speed slower, and needs a large amount of moulds.
Artificial coarse-grained soil grain forming equipment is prepared the invention discloses one kind, it is light to be easy to carry, can do different straight
The circular and artificial coarse-grained soil of elliposoidal in footpath, successfully solves slow and middle the asking loosely for combining of artificial coarse-grained soil speed
Topic, is that experiment basis have been established in the research of coarse-grained soil.
The content of the invention
Goal of the invention：For problems of the prior art, the technical problem to be solved in the present invention is to provide a kind of
It is light to be easy to carry, the circular and artificial coarse-grained soil of elliposoidal of different-diameter can be done, successfully solve artificial coarse-grained soil speed
The artificial coarse-grained soil forming instrument of the slow and middle problem loosely for combining.
In order to solve the above technical problems, the present invention proposes a kind of artificial coarse-grained soil forming instrument, including loading device, into

Be can slide up and down pressure head and the hand pressure bar that is connected with the pressure head on strut, and pressure is applied by the hand pressure bar.
The mold includes mold base and is arranged at some upper model bar of the top mold surface, mould on each
Model groove is provided with type is dry, the size of model groove artificial coarse-grained soil independently of one another according to the shaping on each
Size is set；The lower mould includes lower mold base and some drag bars for being arranged at the bottom mold surface, often
Drag groove is respectively arranged with individual drag bar, when the mold and lower mould are oppositely arranged, the drag bar
The size of number and drag groove is corresponding with the number of the upper model bar and the size of upper model groove respectively.
The both sides of the mold and lower mould are respectively arranged with locating rod and lower locating rod, when the mold is with
When mould is oppositely arranged, the upper locating rod and lower locating rod engage, the position for being accurately positioned the shaped device.
Preferably, the top of upper locating rod is provided with locating slot, and the top of the lower locating rod is provided with locator protrusions, institute
Locating slot is stated to be adapted with the locator protrusions.
It is further preferred that the locating slot is turbination, the locator protrusions is cone.
The auxiliary packing device includes loading hopper and charging rectangular sleeve, and the charging rectangular sleeve is arranged at described
Around lower mould, it is highly higher than the lower mould.
Present invention further proposes the application method of above-mentioned forming instrument：Lower mould is arranged on loading device, in institute
Preservative film is spread on the top for stating lower mould, and charging bucket is then placed around the lower mould, and the height of the casing drum is high
In the top surface of the lower mould；The material that will modulate predetermined quality with hopper is added in casing drum, material is tiled uniform；Use again
The preservative film of formed objects is layered on material above；Mold is placed, the mold and lower mould is set relatively using positioner
Put.
Beneficial effect：Compared with prior art, the artificial coarse-grained soil forming instrument that the present invention is provided is by changing mold
With the artificial coarse-grained soil of spherical or elliposoidal that the upper model groove of lower mould and the size of drag groove can do different-diameter, work as institute
When the coarse-grained soil size for needing changes, it is only necessary to replace mold and lower mould.Producer can be solved using the present invention
The problem loosely combined in the middle of work coarse-grained soil upper and lower hemispheres, while artificial coarse-grained soil manufacturing speed can be greatly improved.
Further, since in preparation process, upper model groove and the entirety of drag groove that mold and lower mould are opened up
Size is the same, uniquely the difference is that the upper model groove and drag groove of shaped device are of different sizes, if claimed every time
Take the material of phase homogenous quantities, then the quality of each bead or ellipsoid is identical with packing after can ensureing to be molded substantially, so as to protect
Card has identical property with the coarse-grained soil of a collection of preparation.
Another further aspect, granule strength can be adjusted in preparation process by controlling outer-penetrating agent and strength of cement, it is specific and
