Description
Technical field
The utility model is related to earthen ruins protection test research and protection field of reinforcement, mainly for ruins body due to losing
Water drying shrinkage, consolidation settlement, vapor transport, salinity crystallization, rainfall snowfall infiltration expansion, ambient temperature and humidity variation etc. cause soil body shape
Become the device tool measured.Device tool can also be applied to the association areas such as geotechnical engineering.
Background technology
The Xinjiang in NORTHWEST CHINA area, Gansu, many ancient times earthen ruins of the domestic remnants in Ningxia and Shaanxi, northern length of wriggling
City, pass city, beacon flint on the vastness gobi of northwest, the friendship river in Xinjiang, Gao Chang, Lou Lan, Niya Ruins, be up and down it is thousands of every year,
In length and breadth in ten thousand, spread all over China.These earthen ruins are with a long history, and some has been cited as world cultural heritage, have very high historical relic to protect
Shield value.Since the ancient times earthen ruins year's harvest is long, environmental change can influence inside soil body stress variation, and these stress variations by
The multifactor impacts such as ruins scale, form, soil mass property.Ruins inside soil body stress variation be cause soil body macroscopic view lesion just
The form of expression is walked, therefore, the stress variation of research measurement inside soil body studies the distress mechanism and preventive protection in ruins
It has a very important significance.At present, the equipment that can not use for reference can accurately characterize the microscopic feature of soil body deformation.
The content of the invention
In order to measure the ess-strain of building inside soil body different conditions, the purpose of this utility model provides a kind of building soil
Internal portion stress-strain measurement device can realize the measurement of inside soil body ess-strain by this measuring device tool.
The purpose of this utility model is reached by following measures：
A kind of building inside soil body stress-strain measurement device adopts instrument containing the soil body, foil gauge, rubber bar, conducting wire sum number, will
Rubber bar is divided into two along longitudinal direction segmentation, adheres to foil gauge on the smooth rubber bar face of half, foil gauge will be posted with melten gel
The uniform closure of one side, foil gauge conducting wire adopted instrument and be connected by rubber bar with number, and then, the other half rubber bar, which aligns, is pressed in patch
Have on the closure layer of foil gauge, form it into a complete rubber bar, rubber bar is embedded in the soil body.
The advantages of the utility model and the advantageous effect generated are：
（1）The rubber bar elasticity modulus that the utility model uses is small, plastic-less deformation, can be by shape when the soil body deforms upon
Change passes to foil gauge, foil gauge is driven to stretch, so as to measure the deformation of the soil body.
（2）Rubber bar has certain waterproof, anticorrosion, anti-external impacts effect, can adapt to Various Complex soil body item
Inside soil body stress-strain measurement under part.
（3）The utility model can be applied to soil body dehydration drying shrinkage, consolidation settlement, vapor transport, capillary water rising, salinity
The measurement for the small strain that the factors such as crystallization, rainfall snowfall, humiture variation generate for a long time.
（4）The utility model can be applied to vibration and the lower instantaneous stress strain measurement of external force effect, in impact masterpiece
It good can still be played a role with lower.
（5）The measuring instrument device is easy to operate, using convenient, low cost, has in measurement inside soil body ess-strain wide
General application scenarios.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
The utility model is further described again below in conjunction with the accompanying drawings：
A kind of building inside soil body stress-strain measurement device, including the soil body 1, foil gauge 2, rubber bar 3, foil gauge conducting wire
4 sum numbers adopt instrument 5.Rubber bar 3 a length of 6cm, diameter 7mm.Rubber bar 3 is divided into two along longitudinal direction segmentation, by half rubber bar
After polishing is cleaned, foil gauge 2 is adhered on burnishing surface, it is with melten gel that the one side for posting foil gauge 2 is equal after the drying of foil gauge 2
Even closure, foil gauge conducting wire 4 are adopted instrument 5 with number by the conducting wire 4 of rubber bar 3 and are connected, and then, the alignment of the other half rubber bar is pressed in
It posts on the closure layer of foil gauge 2, forms it into a complete rubber bar 3, by rubber bar 3 with X, tri- directions of Y, Z are one
Group is embedded in the soil body 1.When the stress transfer suffered by the soil body 1 to rubber bar 3,3 elasticity modulus of rubber bar is small, and non-plastic becomes
Shape has waterproof, anticorrosion, external force resistance percussion.Foil gauge 2 is seated in rubber bar 3, and rubber bar 3 does not produce foil gauge 2
Raw any interference phenomenon.When the soil body 1 deforms upon, can deformation promptly be passed into foil gauge 2, drive foil gauge 2 flexible,
Foil gauge 2 is flexible to be adopted 5 electric signal of instrument with number and is changed into digital signal, so as to measure the ess-strain amount in the soil body 1.
