Description

[Technical field]

[0001] The utility model relates to anchor rod detection equipment in geotechnical engineering, in particular to a displacement measuring clamp used for anchor acceptance test detection. [Background technology]

[0002] In the basic test, creep test, acceptance test and pull-out test of anchor rods, each specification requires displacement measurement of anchor rods. Anchor rods are slender rods, and the displacement measurement points are often installed on tool anchors or jacks 60 due to the lack of a measurement platform. This has the following main disadvantages:

[0003] 1. Improper installation: The displacement measured on the jack 60 is not the displacement of the anchor rod, but includes the displacement of the sliding fixture.

[0004] 2. When installed on a tool anchor, the probe may easily slip due to the small size of the tool anchor.

[0005] 3. The installation space is too small and the dial indicator is too close to the anchor rod, which may cause data distortion due to the tilted anchor rod touching the dial indicator.

[0006] To solve the above problems, we provide a solution. [Contents of the utility model]
