Description
Technical field
The protection test of the utility model earthen ruins fissure grouting is studied and protection reinforcing engineering field, is a kind of test rammed earth
The practical device of ruins slurries grouting pressure can also be applied to the association areas such as geotechnical engineering.
Background technology
The Northwest of China's arid and semi-arid environment, remnants have substantial amounts of ancient times earthen ruins, big such as Gansu Qinan County
Ground gulf human living ruins, the Ruins of the Ancient City of Jiaohe of In Turfan In Xinjiang, Yinchuan West Xia Dynasty mound etc..By construction process and natural environment
It influences, earthen ruins ontological existence the crack or crack of various form and scale.Investigation finds that mainly there are weathering fissures in crack, unload
Lotus crack, construction process crack etc..Weathering fissures refer to ruins body weakness zone, along weakness zone under natural force effect
Gradually profound level weathering forms secondary interstice, and shape is up-small and down-big, opening width 1-10cm, how straight, no charges, and length is wide
It is narrow etc.；Relief joint is often generated roomy crack and the crack of association after the body Collapse Deformation of ruins, and crack is opened
10-50cm is spent, in forms such as broken line, straight line, curves, there are later stage charges, charges are mostly loose to peel off soil more；Construction process is split
Gap is primarily referred to as the indirect stubble building gap crack of ruins body, and what the building gap rammed between layer, different times were built connects stubble
Gap, cracks aperture 3-8cm are mostly connectivity crack, and gap is more straight between ramming layer, nearby without secondary interstice.Building
Technique fractured zones are distributed mainly on this walling of ruins and connect stubble and ram the weaker layer of layer intensity in each ruins body
Face；The crack cutting ruins body of different type, different scales, causes wall to deform flare.Meanwhile crack carries for weathering
Favourable passage has been supplied, so as to exacerbate the development in crack, has ultimately resulted in ruins body partial collapse.
Crack is since development severity is different, some, which have been developed through ruins body, forms perforation crack, even
Part loses the outer sudden strain of a muscle of constraint or tilts, and wherein some is just developed, and there is no form perforation crack.The development in crack destroys
The structure in ruins, reduces the physical and mechanical property in ruins, ruins may be triggered to cave under exogenetic process, especially unloaded
The generation in lotus crack mostly forms the stabilization for influencing ruins due to wall base sapping.It is that earthen ruins are able to protect one that crack, which reinforces,
Highly important process means.
At present, slip casting is mostly using the external Grouting Pipe of medicine inhalation syringe is borrowed, and then artificial manual injection device, slurries lead to
It crosses Grouting Pipe and enters crack, this progress for relying primarily on grouting personnel's micro-judgment slip casting, than relatively low, slip casting reaches grouting pressure
Less than the depth in crack, earthen ruins body crack cannot be fine and be made up, and last a very long time, blowing and raining, crack still influences
The stabilization of earthen ruins.Therefore, the test to grouting pressure and control are come to inhibit earthen ruins crack be always it is contemplated that solve
The problem of.
The content of the invention
In order to overcome the shortcomings of artificial micro-judgment earthen ruins crack grouting, the purpose of this utility model is to provide one kind
Earthen ruins crack grouting pressure test device.The utility model can accurately test slip casting different layers by electronic digital display tensiometer
Position, the grouting pressure of different phase, to make earthen ruins crack up, protection ancient records and relics provide a kind of tool for grouting in loose.
The purpose of this utility model is realized by following technical solution：
A kind of earthen ruins crack grouting pressure test device is by electronic digital display tensiometer, horizontal force testing jig, injection
Device, Grouting Pipe, crannied undertaking slurry container and hand wheel shaft composition.Electronic digital display tensiometer is fixed on horizontal force testing jig
On, syringe end connection Grouting Pipe, afterbody connects electronic digital display tensiometer, and hand wheel shaft is connected with electronic digital display tensiometer, has
The undertaking slurry container in crack is placed on immediately below slip casting pipe end.
The advantages of the utility model and the advantageous effect generated are：
（1）Convenient, easily detection.Before different crack patterns, different materials proportioning slurries grouting pressure test, manually suck
Be in the milk slurries, stirs horizontal force testing jig handwheel, and the grouting pressure of different phase can be directly read.
（2）Detachably, it is portable.Crack grouting pressure Special testing device is small, is convenient for carrying, easy to operate, note
Emitter can be dismantled arbitrarily, the quantitative analysis of different crack patterns, different materials proportioning slurries grouting pressure be realized, by identical
The closely knit situation of the effective interpretation slip casting of material mixture ratio slurries different layers position crack grouting pressure, also can be according to the same terms difference material
The workability of material proportioning slurries.
（3）Reduce Subjective Factors.Portable slit grouting pressure Special testing device, detection method is simple and nothing
Damage reduces Subjective Factors, and standard set-up effectively raises the precision of detection, and operation sequence is unified, normative strong.
（4）The utility model is simple in structure, easy to operate, and indoor and scene can survey the grouting pressure of slurries
Examination.Be it is a kind of can quickly, the device of reliable determination grouting pressure, the device replenished to earthen ruins crack grouting process operate
The blank of difficulty research, the research for the site operation difficulty or ease of earthen ruins crack grouting reinforcing provide a kind of new technology hand
Section.It has a wide range of applications in terms of earthen ruins fissure grouting implementing measure evaluation.
Description of the drawings
Fig. 1 earthen ruins crack grouting pressure test dedicated unit schematic diagrames.
