Problems solved by technology

[0002] In modern engineering, columns and piles are more and more widely used, but due to the influence of foundation strength, stability and various environmental factors, the column or pile will be deformed such as offset, inclination, settlement, etc. If the deformation is too Large, will have a great impact on the project
Existing detection methods, such as manual detection and embedded sensors, are complex, not economical, and not suitable for real-time detection of large-area piles

Embodiment Construction

[0089] The present invention is a kind of method that detects that column or pile changes its inclination angle, settlement change with time, concrete implementation is carried out according to the following steps:

[0090] step 1:

[0091] First of all, determine the reference object, which can be determined by making or selecting the reference object. This reference object must change with time, and there will be no phenomenon such as deviation or a small amount of change.

[0092] Step 2:

[0093] Fix the red light reticle at two different positions above and below the reference object, so that the cross laser irradiated by it can fall on the center of the measured column or pile body, and keep the position of the red reticle unchanged. The distances between the upper and lower cross cursor projection points and the ground are h and h′ respectively; figure 1 shown.

[0094] Step 3:

[0095] At the position where the cross cursor on the detected column or pile is compare...

Abstract

A method for detecting the inclination angle and settlement change conditions of a column or pile with time comprises the following steps: completely fixing a red light cross line marker on a primary standard reference, carrying out cross scale marking on the column or pile, and allowing a cross scale mark to overlap with cross laser; fixedly arranging the red light cross line marker on the column or pile to be detected as the primary standard reference by adopting a same process, marking a cross scale by contrasting a next column or pile to be detected, and repeating the process; opening the red cross line marker a period of time later, and judging that the column or pile to be detected has no deformation if the projection of the cross laser overlaps with the original scale mark; contrasting the projection with the original scale mark if the projection of the cross laser does not overlap with the original scale mark, and reading the value on the cross scale mark; and calculating to obtain the inclination angle and settlement amount in the left and right direction, and the back and forth direction of every column or pile to be detected. The method for detecting the inclination angle and settlement change conditions of the column or pile with time, provided by the invention, is simple and convenient.

Description

technical field [0001] The invention relates to a method for detecting changes in inclination and settlement of columns or piles over time, and belongs to the technical field of geotechnical engineering applications. Background technique [0002] In modern engineering, columns and piles are more and more widely used, but due to the influence of foundation strength, stability and various environmental factors, the column or pile will be deformed such as offset, inclination, settlement, etc. If the deformation is too Large, it will have a great impact on the project. Existing detection methods, such as manual detection and embedding sensors, are complex, not economical, and not suitable for real-time detection of large-area piles. Contents of the invention [0003] The purpose of the present invention is, aiming at the column or pile in modern engineering changes with time, the detection problem of its inclination angle, settlement change, the present invention proposes a k...
