Description
Technical field
The utility model belongs to rock mechanics and engineering technical field, and in particular to a kind of prismatical joint rock mass physical mould
Type.
Background technology
The method for making prismatical joint rock mass physical model at present typically first uses rocks gypsum mixing material or cement
Mortar makes cylinder, then is bonded with cement mortar, and the connection under native state between each cylinder of column jointed rock mass is mainly by post
Mutual extruding and frictional force between body, therefore the interaction that existing preparation method can not preferably reflect between cylinder.Separately
Outside, existing preparation method is unable to one-shot forming, it is necessary to which the vibration produced in secondary operation, process may be produced in cylinder
Raw damage, and the connection destroyed between cylinder, and then follow-up dynamic characteristic test result may be influenceed.Meanwhile, for convenience of secondary
Processing, cylindrical material have selected the relatively low plaster of Paris of intensity, its intensity will well below sillar intensity.
Utility model content
The purpose of this utility model solves the above problems there is provided a kind of closer to column jointed rock mass under native state
The prismatical joint rock mass physical model of architectural characteristic.
In order to solve the above technical problems, the technical solution of the utility model is：A kind of prismatical joint rock mass physical model, bag
Including mold frame, mold frame includes six face post cavitys of honeycomb arrangement, the angle of six face post cavitys and vertical plane is 0 °-
It is 90 °, tightly packed in six face post cavitys to have cylinder.
Preferably, low melting material or water-soluble material of the mold frame by fusing point less than 100 DEG C are made.
Preferably, the material of the mold frame is one kind in polycaprolactone, polyvinyl alcohol, ABS resin or paraffin.
Preferably, the material of the cylinder is one kind in cement mortar, concrete or plaster of Paris.
Preferably, the angle of the six faces post cavity and vertical plane is 0 °, 15 °, 30 °, 45 °, 60 °, 75 ° or 90 °.
Preferably, the common cavity wall of the six faces post cavity is provided with the cylinder in the connecting hole run through, six face post cavitys
It is connected by connecting hole.
The beneficial effects of the utility model are：A kind of prismatical joint rock mass physical model provided by the utility model, leads to
The mold frame for crossing 3D making links together cylinder so that the interaction of cylinder is closer to prismatical joint under native state
Rock mass, and make simple and convenient.

Embodiment
The utility model is described further with specific embodiment below in conjunction with the accompanying drawings：
As depicted in figs. 1 and 2, rock mass physical model in prismatical joint of the present utility model, including mold frame 1, mould frame
Frame 1 includes multiple six faces post cavitys 2 of honeycomb arrangement, and the section of six face post cavitys is regular hexagon.In each six faces post chamber
Tightly packed in body 2 to have cylinder 3, the section of cylinder is also regular hexagon.
Mold frame 1 is made up of 3D printing technique, during 3D printing from low melting material (fusing point less than 100 DEG C best) or
Water-soluble material is used as 3D printing material.Such as polycaprolactone, polyvinyl alcohol, ABS resin or paraffin, ABS resin refers to third
Alkene nitrile-BS, it is a kind of intensity height, good toughness, thermoplastics type's macromolecule material easily processed into type
Material.
Cylinder 3 is formed by the perfusion of cement mortar, concrete or plaster of Paris.Needing to make the mould closer to real conditions
During type, also composite etc. can be selected to be made according to demand, composite is by metal material, ceramic material or high polymer material
The heterogeneous material prepared Deng two or more material by combination process, various materials take mutually long benefit in performance
It is short, cooperative effect is produced, the combination property of composite is better than former composition material and is met a variety of requirements.
Due to being significantly less than cylinder to mold frame intensity itself, very little is influenceed on the final data of test, can not be removed
The direct pressure testing of mold frame.Also it can be provided with the common cavity wall of six face post cavitys 2 in the connecting hole run through, six face post cavitys
Cylinder is connected by connecting hole, so as to be removed before pressure testing by modes such as solvent dissolving or high-temperature fusions after mold frame, post
Body still links together.
Because pressure testing machine can only provide the power of single direction, prismatical joint rock mass is studied for convenience in different directions
The angle of structure change and destruction situation during stress, six face post cavitys 2 and vertical plane can change between 0 ° -90 °, so that
So that the cylinder produced has specific angle.Fig. 3 to Fig. 9 is respectively that the angle of six face post cavitys and vertical plane is respectively
0 °, 15 °, 30 °, 45 °, 60 °, 75 ° and 90 ° of schematic diagram.
The manufacturing process of above-mentioned prismatical joint rock mass physical model is as follows：
Mold frame is made first with digital modeling techniques and 3D printing technique, setting is needed according to experiment during modeling
The angle of six face post cavitys.Printed material selection polycaprolactone (POLYCAPROLACTONE AVERAGE MN CA.42500) etc.
Low melting material (being less than 100 DEG C) or polyvinyl alcohol (polyvinyl alcohol, vinylalcohol polymer) etc. are water-soluble
Property 3D printing material.Print after mold frame in six face post cavitys outside cement injection mortar or concrete, mold frame
Upper bush is covered until material Cheng Mo.
The prismatical joint rock mass physical model of this patent, simplifies the manufacturing process of prismatical joint rock mass physical model,
Prismatical joint rock mass that can be under truer simulation native state.
One of ordinary skill in the art will be appreciated that embodiment described here is to aid in reader and understands this reality
With new principle, it should be understood that protection domain of the present utility model is not limited to such especially statement and embodiment.
One of ordinary skill in the art can these technical inspirations according to disclosed in the utility model make and various do not depart from this practicality
New substantive other various specific deformations and combination, these deformations and combination are still in protection domain of the present utility model.
