Problems solved by technology

However, this measurement method can only measure the distance deviation of a certain position on a straight line, such as settlement and inclination, and the displacement of buildings and structures is mostly spatial displacement. Therefore, how to use existing measurement tools to cooperate with better measurement methods It is necessary to measure the spatial displacement of buildings and structures

Embodiment 1

[0032]Combinefigure 1 ,2As shown, the method of measuring the spatial displacement of the measurement of the present invention is used to measure the deformation of the buildings of the new building. The specific process is as follows:

[0033](1) Space geometry mentioned that two points are determined a straight line, not in the same straight line, one plane, such asfigure 2 As shown, the three points A, B, C do not in the same straight line are selected as the measurement reference point, the A, B, and C. The three points are fixed, and it is fixed without moving, and does not change as the settlement or deformation of the constructive; Points A, B, and C determine a plane α, with a point as the origin, the straight line AB is the X-axis direction, and the straight line perpendicular to the straight line AB is the Y-axis direction, and the X-axis, the positive direction of the Y-axis is directed toward the direction. The normal direction of the plane α establishes a spatial coordinat...

Embodiment 2

[0046]Combinefigure 1 ,3, 4, the method of measuring the spatial displacement of the measurement of the measurement of the present invention is used to measure the sink and peripheral convergence deformation of the tunnel vault, and the basic principles and steps of the present invention and the first embodiment of the new build building buildings. Basically, the difference is that in this embodiment, a reference point O point is added outside the tunnel for reviewing A.1, B1, C1Three points change, here A1, B1, C1Three points are equivalent to the A, B, C point in Example 1, just for the sake of different, according to A1, B1, C1The spatial coordinate system established by the three points is likeimage 3 Indicated.

[0047]Further, such asFigure 4 As shown, the measuring point D is arranged in the same tunnel in the same tunnel with the reference point A1, B1, C1.1Add to measure the sinking of the vault, arrange E1Point is used to measure the periphery convergence, and the measurement...

Abstract

The invention provides a method for measuring the spatial displacement of a building based on the spatial position relationship of coordinate points. The method carries out the real-time three-dimensional space measurement of a designated point of the building by using the three-dimensional coordinate spatial relationship of three reference points and combining with a measurement tool. By adopting the measuring method disclosed by the invention, the spatial displacement change of the specified point on the building can be more effectively and intuitively monitored, so that the three-dimensional spatial displacement of the building is monitored, more powerful data support is provided for construction and maintenance, an engineering constructor and an operation maintenance party are helped to make more favorable judgment on the health condition of the building, and the engineering risk can be effectively reduced and is prevented.

Description

Technical field[0001]The present invention relates to the field of engineering construction monitoring, and in particular, a method of measuring the spatial displacement of the construction of the constructive site based on the positional relationship between the coordinate point spatial position.Background technique[0002]With the continuous development of my country's infrastructure industry, the construction of buildings such as deep base pit, high-side slope, bridge tunnel is increasing. At present, for the deformation measurement of the construction, generally measurement is mostly the displacement parameters of a particular point on the construction of the building, mainly using instruments such as levels, all-station, and other instruments. However, this measurement method can only measure the distance deviation of a location point on the straight line, such as settlement, tilting, and the displacement of the built-in is more spatial displacement, so how to use the existing me...
