Description
Technical Field
The utility model relates to the technical field of building detection equipment, in particular to a high-strain guide frame.
Background
The high strain detection is a detection method for judging the vertical compression bearing capacity and the integrity of a pile body of a single pile, a heavy hammer is used for impacting the pile top in an experiment, the speed and force time-course curve of the pile top are measured in an actual mode, and the speed and force time-course curve is analyzed through a fluctuation theory. The basic principle of high strain detection is that an impact force is axially applied to the pile top to enable the pile to generate enough penetration, the response of the mass point stress and the acceleration of the pile body generated by the impact force is actually measured, and the vertical compression bearing capacity of the single pile and the integrity of the pile body are judged through the analysis of a fluctuation theory. The heavy hammer is used to impact the pile top to produce enough relative displacement between pile soil to excite the soil resistance around the pile and the bearing force at the pile end.
At present, a crane is usually adopted to lift the heavy hammer to a certain height during detection, then the heavy hammer is knocked manually to release the free falling of the heavy hammer, a large amount of time is consumed for adjusting the heavy hammer in the test process in order to ensure that the heavy hammer is aligned with the foundation pile, the alignment precision of the heavy hammer and the foundation pile is difficult to ensure, and the risk that the heavy hammer easily slides down to cause damage to personnel and instruments and the like exists.
