Horizontal displacement observing scale, measuring structure, sluice observing system and observing method

Abstract

The invention relates to a horizontal displacement observing scale, a measuring structure, a sluice observing system and an observing method. The horizontal displacement observing scale comprises a horizontal pedestal (10), a vernier scale (20) and a beacon scaffold (30), wherein the horizontal pedestal (10) is horizontally arranged and is provided with an opening in the center; the vernier scale(20) is arranged on the horizontal pedestal (10), and comprises a scale rod (21) and a measuring claw (22); the inner edge line of the measuring claw (22) is vertical to the horizontal pedestal (10);the beacon scaffold (30) is fixedly connected to the measuring claw (22); a center line is arranged on the beacon scaffold (30); the center line is superposed with the inner edge line of the measuringclaw (22). The horizontal displacement observing scale provided by the invention is not affected by the environment, can still measure the horizontal displacement of a building more accurately undera windy weather condition, and also has the advantages of simple structure and low cost.

Description

technical field [0001] The invention relates to the field of horizontal displacement observation of buildings, in particular to a horizontal displacement observation scale, a measurement structure, a sluice observation system and an observation method. Background technique [0002] The observation of buildings is a basic work that needs to be persisted for a long time. The main purpose is to grasp the deformation and displacement of buildings and the operation of buildings under complex loads, so as to detect and deal with problems that endanger the safety of buildings in an early stage. Make sure the building is safe. [0003] For example, in the construction of sluices, measuring the horizontal displacement of the sluice body is of great significance for analyzing the stability of the sluice body. The most widely used observation method for measuring the horizontal displacement of buildings is the datum line method, which is further divided into the line of sight method, ...

Problems solved by technology

However, the previous line-of-sight method has the following disadvantages: 1) It is necessary to measure the deviation values ​​in two directions and take the average; The line error is relatively large, and the accuracy is not high (the general accuracy is only 1mm); 3) The previous observation scale is self-weight, relying on gravity to generate the plumb surface of the vertical line of sight, and the movable target is easily disturbed by sharp and other natural environments. The measurement error is large; 4) It is difficult to avoid the reading collimation error due to reading with the naked eye

[0005] Although the tension line method and the laser alignment method have their own advantages, the tension line method is only suitable for straight-line buildings, and has high requirements for natural conditions. It needs to work without wind and interference. The cost of the laser alignment method High, large one-time investment, high requirements for vacuum degree, limited application range at present
