Example Embodiment

[0017] Such as figure 1 Shown: Observation method of foundation settlement of high-precision rolling mill, which includes:

[0018] Choose a stable basis on the side of the rolling line of the rolling mill, and set up 3 observation points at different positions, numbered as point A, point B, and point C. The distance between the three points is not more than 50 meters;

[0019] In the first observation, the four settlement points of the rolling mill were measured with the leveling control point BM, and the measured value is considered to be the correct value; then the first value of settlement point I was used as the benchmark to measure the three points A, B, and C, and we got Draw out three values, and finally close to the BMI level point;

[0020] When observing the settlement point of the rolling mill in the future, use point B as the benchmark for observation. In each observation, first observe whether there is a change between points A, B and C. If there is no change, observe ...

Abstract

The invention relates to an observation method for the foundation settlement of a high-precision rolling mill, belonging to the field of foundation settlement detection. The observation method comprises the following steps: selecting a stable foundation in the rolling line-side direction of the rolling mill, setting up three observation points at different parts, and numbering the three observation points as a point A, a point B and a point C, wherein the distance between every two points is no more than 50 m; during initial observation, performing guiding measurement of the level control point BM to four settlement points of the rolling mill, wherein measured values are considered to be correct values; then performing guiding measurement of the initial value of the sinking point I to thepoints A, B and C to obtain three values, and finally, allowing the three values to return to a BMI leveling point to form a closed line; and carrying out observation on the settlement points of the rolling mill, with the point B used as a reference point, wherein in each observation, whether the points A, B and C have any change or not is observed at first, sinkage amounts observed at the four settlement points of the rolling mill are taken as corrected value if no change occurs, or other operation is performed if the points A, B and C have changes. The observation method of the invention issimple and fast to operate, accurate and reliable in measured values, lowers labor input and reduces labor intensity.

Description

technical field [0001] The invention relates to foundation settlement detection, in particular to an observation method for rolling mill foundation settlement. Background technique [0002] During the installation process of the rolling mill, settlement observation is also a very important link, and the accuracy of the observed settlement value is also very high. Generally, a settlement point is buried in each of the four corners of the rolling mill foundation, a total of 4 points, to observe the four points regularly The measured results are provided to the technical department. Before the fine adjustment of the rolling mill, the settlement is used as a reference. After the settlement value of the observation period is relatively stable, or does not exceed the range, according to the regulations, the observation point of the settlement measurement The stability index is set at 2mm / half a year (ie 0.01mm / day). According to the regulations, without good natural conditions, i...
