Description
Technical field
The utility model is related to the deformation measurements on building basis under field of measuring technique, especially mining influence.
Background technology
The exploitation of underground mineral can influence the stability of fabric structure on ground to a certain extent, even result in building
The deformation and damage of object, therefore, exploitation unit need to compensate its loss.
Currently, the measure of indemnity of loss is mainly according to building tear width and other structures deformation behaviour.This brings
Some problems, 1. since other non-mining influence factors, building itself also will produce malformation, it is difficult to judge whether be
The damage brought is adopted, qualitative to reparation causes difficulty；2. the structure of the deformation of building with itself under mining influence
Intensity and quality and its build time limit relationship it is very big, in the deformation on identical building basis, it is high-quality, construction the time limit it is short
The malformation of building is usually smaller, and obtaining after mining is compensated in the time limit, and the indemnity obtained is less, but by
It has been generated in foundation deformation, the maintenance cost in later stage increases severely, and use value substantially reduces, for the owner of such building
For be inequitable；3. some buildings owner in order to obtain higher reparation, artificially expands fabric structure change intentionally
Shape, for example, increasing the width in crack using jack etc., which results in the wastes of buildings and resources, have also ruined social conduct.
To solve the above-mentioned problems, the indemnity for damage foundation of change building is needed.Due to building foundation deformation with
Building itself structural strength etc. is unrelated, while it is not influenced by human factor, accordingly it is contemplated that as reparation according to
According to.
Invention content
Problem to be solved in the utility model is how to measure the deformation on building basis.
The deformation measuring device on building basis under mining influence, including deviational survey bar and total powerstation, the quantity of deviational survey bar is extremely
It is 4 few, it is inserted vertically into each corner in building outer, is located in the basis other than structure foundation, horizontal peace on deviational survey bar
Equipped with double-shaft tilt angle sensor, there is measurement to indicate at the top of deviational survey bar, total powerstation is located at outside building, aims at each measurement mark, surveys
Obtain the station-keeping data of each measuring rod.
Measuring rod material is plastics or metal, and length is between 1-3m.
Measurement mark at the top of measuring rod is the sphere that diameter is more than 2mm, and measurement mark is following to be partly embedded into building base
In plinth.
It measures mark by telescoping mechanism to be connected with deviational survey bar, usually in its retraction deviational survey bar, when measurement is stretched by its.
Since the double-shaft tilt angle sensor on deviational survey bar can react the inclination of house foundation, the deviational survey bar phase that total powerstation measures
The relative settlement, stretching and distortion of basic each section can be reacted position data, which can measure the change of house foundation comprehensively
Shape.
Underground mineral producing area is generally rural area, and the height of building is at two layers or so, therefore the basis of building becomes
Shape and building weight itself are substantially unrelated, and the malformation of building itself is only related to its foundation deformation and structural strength,
Only Fundamentals of Measurement is needed to deform, without measuring the malformation of building itself, while foundation deformation is not influenced by human factor,
Accordingly it is contemplated that as reparation foundation.
It measures mark by telescoping mechanism to be connected with deviational survey bar, usually in its retraction deviational survey bar, when measurement is stretched by its.
Telescoping mechanism plays protective effect to measuring mark, avoids its long-term damage and deformation being exposed to suffered by the external world.
The deformation extent on building basis is combined with the construction time limit of building, construction cost, as mining influence
The Main Basiss of lower building damage measure of indemnity, in the same circumstances, the construction time limit of building is shorter, and indemnity is corresponding
It is higher.This compensates for the follow-up use value for building the short building of the time limit to a certain extent, and measure of indemnity is more reasonable, public
It is flat.

Specific implementation mode
The deformation measuring device on building basis under mining influence, including deviational survey bar and total powerstation, the quantity of deviational survey bar is extremely
It is 4 few, it is inserted vertically into each corner in building outer, is located in the basis other than structure foundation, horizontal peace on deviational survey bar
Equipped with double-shaft tilt angle sensor, there is measurement to indicate at the top of deviational survey bar, total powerstation is located at outside building, aims at each measurement mark, surveys
Obtain the station-keeping data of each measuring rod.The present embodiment is suitable for the case where building distribution more disperses, when building is concentrated
When distribution, the distribution of net formula can be used in deviational survey bar, measures the foundation deformation of full wafer residential block building.
Measuring rod material is plastics or metal, and length is between 1-3m.
Measurement mark at the top of measuring rod is the sphere that diameter is more than 2mm, and measurement mark is following to be partly embedded into building base
In plinth.It is the sphere that diameter is more than 2mm to measure mark, is convenient for the alignment of total powerstation laser facula, improves each multi-angle laser ranging
Accuracy.Actual range subtracts radius of sphericity equal to laser ranging.
It measures mark by telescoping mechanism to be connected with deviational survey bar, usually in its retraction deviational survey bar, when measurement is stretched by its.
The application method of the device：
A drills on the basis of building, and deviational survey bar is inserted vertically into and is fixed, initial tilt value is zero, then is used
Total powerstation, towards each measurement mark is aimed at, measures each initial station-keeping data for measuring mark in building difference, in conjunction with
Measure the inclination angle of the relative position and deviational survey bar of mark, you can obtain the initial station-keeping data of each deviational survey bar；
B, at regular intervals, record obliquity sensor reading measures the station-keeping data of each deviational survey bar；

Total powerstation is located at the corner direction of building when measurement, while measuring the measurement mark on the adjacent both sides in corner.
After measuring every time, the state of ground near lower deviational survey bar is photographed to record, before measuring next time with there and then by it
Planar condition compares and analyzes, and judges whether there is artificial the case where moving deviational survey bar.
After the deformation extent for determining building basis, it is combined with the construction time limit of building, construction cost, as
The Main Basiss of building damage measure of indemnity under mining influence.
In the same circumstances, the construction time limit of building is shorter, and indemnity is accordingly higher.
