Description

Technical Field

[0001] The utility model relates to the technical field of building measurement, in particular to a spliced ​​telescopic ruler for measuring the depth of a rotary bored pile hole. Background Art

[0002] Rotary cast-in-place piles refer to piles made by forming pile holes in the foundation soil at the construction site through the construction method of rotary drilling rigs, placing steel cages inside and pouring concrete. The rotary drilling rig first uses a barrel-type drill bit with a valve at the bottom to rotate and crush the rock and soil, and directly load it into the drill bucket. The drill bucket is then lifted out of the hole by the drilling rig lifting device and telescopic drill rod to unload the soil. This cycle is repeated, and soil is continuously taken and unloaded until the designed depth is reached.

[0003] The traditional rotary cast-in-place pile hole depth measurement uses a measuring rope and a heavy hammer to achieve hoisting measurement, but the heavy hammer and measuring rope can move downward in the cast-in-place pile hole. The hole depth measurement data is often not accurate enough, and it is necessary to manually sense whether the heavy hammer is in place. It relies on manual experience and human factors intervene too much. The depth of the cast-in-place pile hole is estimated by estimation, which is easy to cause large measurement errors and greatly mislead the judgment of the final hole depth. Therefore, it is necessary to improve the accuracy of rotary cast-in-place pile hole depth measurement.

[0004] Based on this, the inventor has designed a spliced ​​telescopic ruler for measuring the depth of rotary bored cast-in-place pile holes to solve the problem of inaccurate pile hole depth measurement of rotary bored cast-in-place piles, and thus proposed the present application.
