Description
Technical field
The present invention relates to one kind to build detection structure, more particularly, to a kind of building subsidence observation method and structure.
Background technology
Whether the purpose of building subsidence observation is uniform by observing grasp building settlement, to judge design and construction
Whether situation is reasonable, if influences structure and provides data safely, true to reflect building settlement situation, this requires settlement observation
As a result must be accurately and reliably.Under normal circumstances, in order to observe sedimentation situation, observation datum mark is buried in the surrounding of engineering, is passed through
Observe datum mark and grasp sedimentation situation.It is easily heated but commonly observation datum mark is easily influenceed easily by Effects on Engineering by Changes in weather
Swollen shrinkage influences, and causes error of observation data bigger than normal, so as to can not accurately reflect building settlement situation.
The content of the invention
The present invention is easily influenceed by Changes in weather primarily directed to easy by Effects on Engineering present in prior art, easily heated
Swollen shrinkage influences, the technical problem of the larger grade of measurement error, there is provided a kind of simple in construction, construction cost is relatively low, is not easy by engineering
Influence, be not easy to be influenceed by Changes in weather, be not easy to be affected by thermal expansion and contraction, the less settlement observation method of measurement error and structure.
The above-mentioned technical problem of the present invention is mainly what is be addressed by following technical proposals：Buried in skin face
Provided with some working base points, three datum marks and four auxiliary base points, benchmark are embedded with surrounding's engineering foundation of building
Point is made up of concrete pier and round steel, and concrete pier is coated with sand protective layer, and concrete pier top portion is provided with a cavity, and round steel is extended by concrete pier bottom
To cavity, covered with reinforced mesh on cavity, concrete bed course has been poured outside reinforced mesh, in working base point is connected to by screw flight
Formed on threaded steel pipe, fixed angle steel is fixedly connected with skin face, inner thread steel pipe is welded with fixed angle steel, it is interior
It is cased with fixing steel box outside threaded steel pipe, screw rod outside weld is connected to a steel ball, and auxiliary base point is made up of concrete column, buried in concrete column
There is reinforcing bar, reinforcing bar head is exposed at outside concrete column, and steel loop is welded with reinforcing bar.
Working base point is in same level.The elevation of water is tried one's best the position for being maintained at nearer from the ground, optimal
Choosing height is 1 to 2 meter of height from the ground.
The distance of datum mark and building is 50 meters to 100 meters.The triangle formed between three datum marks is building
It is enclosed in the delta-shaped region.
Auxiliary base point is arranged on the corner of building, and the distance of auxiliary base point and building is 10 meters to 20 meters.Four
The quadrangle that individual auxiliary base point is connected into is in the delta-shaped region that three datum marks are connected into.
When detecting the sedimentation degree of building, the first step passes through three datum marks successively all auxiliary in observation visual angle
Datum mark, examine the relative stability of datum mark and auxiliary base point；Second step is observed and regarded successively by four auxiliary base points
All working basic point in angle, the eccentricity using special instrument through steel loop observation steel ball.When auxiliary base point or work base
When point is blocked by building, this group of eccentricity data can be excluded；When the stability of auxiliary base point is bad, the auxiliary base is excluded
The data gathered on schedule.
Under normal circumstances, special instrument is the high-precision level of in the market buying.
Therefore, the present invention has simple in construction, and construction cost is relatively low, is not easy by Effects on Engineering, is not easy by Changes in weather shadow
The features such as sound, is not easy to be affected by thermal expansion and contraction, and measurement error is smaller.
