Description
Technical field
The present invention relates to underground engineering vibration-absorptive material collaborative design and development technical fields, and in particular to a kind of indoor ground power of docking
Learn the foam concrete sample preparation facilities and method of testing machine.
Background technique
In recent years, infrastructure construction in china development is quick, large quantities of traffic tunnels, hydraulic tunnel, Large Underground Structure
Engineerings such as (groups) are built up and come into operation in succession.Among these, it is built in the tunnel or large underground structure in highlight lines area, often
It often will receive the threat of earthquake, meet with seismic events.A series of newest earthquakes, which are reported, to be shown under severe earthquake action, underground structure
Do not ensure that in a safe condition always, different type, the destruction of different degrees of structure can happen occasionally, and be with tunnel earthquake
Example, including portal cracking, headwall are damaged, avalanche soil sand；Barrel roadbed pucking, cracking, lining cutting is mobile, adjunct destroys, infiltration
Etc..Therefore, for each underground engineering on highlight lines area, it is necessary to do Aseismatic Design to it.Underground engineering subtracts
Shake design is mainly shown as, and buffer layer is arranged between tunnel-liner or applies damping filling around underground structure, uses
Material be mainly foam concrete.Foam concrete light weight, bullet mould is low, water absorption rate is low, has comparable flexible and ductility,
Damping and buffer performance are outstanding, and shock loads have good absorption and dispersion over the ground.
The one kind of foam concrete as rock-soil material, related physical, mechanics parameters can be real in ground science
It tests on all kinds of rock-soil mechanics testing machines in room and obtains, the science of test result is widely accepted.But it is also noted that one
A problem, i.e., the indoor rock-soil mechanics testing machine of mainstream, required sample must be standard size, standard sample usually quilt on the market
It is required that be processed into having a size of(Represent the basal diameter of cylindrical specimens) cylindrical body.Generally, for one
As rock material, such as granite, gneiss, limestone etc., their intensity are larger, can stand water drilling punching coring, cylinder
A series of postprocessing working procedures such as polishing, end polishing, so being not difficult successfully intercepts out standard sample in bulk sample.But for
Foam concrete, it is this that foaming agent aqueous solution is mechanically prepared into foam, then foam is added containing siliceous raw material, calcareous
In the slurry of raw material, water and various additives composition, through artificial porous material made of mixing, moulding by casting, maintenance, by force
Degree is too low, and uniaxial compressive strength probably only has several megapascal to more than ten megapascal；And its internal structure is very loose fragile, cannot stand
The punching disturbance of equipment and sanding and polishing, method of regularlying sample handle by force very likely material is caused it is irreversible
Injury.Unfortunately, it is consulted by the retrieval to existing document and patent, finds the foam coagulation of existing maturation
Native preparation method and relevant apparatus are mostly used for production large volume sample, intercept standard cylinder on these large volume samples,
Sample material will be dramatically damaged, physics, the mechanics parameters of sample are influenced, these influences are any prior art institutes
It is immeasurable.Although also once mentioning some arbitrary dimension foam concrete samples of capable of preparing in existing document and patent
Method, but matched mature automation equipment is seldom, even if in the presence of also being tried far from realization and all kinds of indoor rock-soil mechanics
Test the interface differential technique of machine.In addition there are two problems also it is noted that one is the Bulky foam coagulation of conventional method preparation
Earth material parameter accuracy is troubling, and physics, the mechanical characteristic of large volume sample can only often accomplish whole control, relevant parameter
Accordingly also can only considered as a whole parameter, as its internal material whether uniformly, property it is whether unified etc., these all must not and
Know.The second is conventional foam coagulation soil sample preparation facilities, dimensional units are mostly " rice " grade, it is clear that cannot be with standard sample " millimeter "
The dimensional units of grade match.
Each more than solving the problems, such as, best approach is exactly the energetic disturbance avoided to sample, for example drills through, polishes, throws
Light etc. restudies and designs the foam concrete sample preparation facilities to match with standard sample dimension scale, from whole process
Loopful section manipulates preparation process, accurately controls sample physics, mechanics parameters and its variation comprehensively, while guaranteeing it
Material is uniform, whole mutually to coordinate with local characteristics parameter；Furthermore, it desired to device high degree of automation itself, manual errors are small, most
Eventually, it is docked comprehensively in terms of technology and material two with indoor rock-soil mechanics testing machine realization；However, there are no phases in the field at present
Equipment is closed, how to design a kind of device for meeting above-mentioned requirements into a urgent problem.
