Problems solved by technology
[0004] The purpose of the present invention is to provide a stable three-dimensional pile hole detector for the problems of inconvenient use of existing detection instruments and the inability of the measurement data to better reflect the diameter and verticality of the pile hole when detecting the quality of pile hole formation. The detector can perform three-dimensional scanning on the wall of the pile hole, and the collected data is sufficient and stable, and can better reflect the hole diameter and verticality of the pile. It is easy to use and has high detection efficiency.

The invention discloses a stable three-dimensional pile hole detector, which comprises a measurement and control computer, a numerically controlled winch, a stabilizing plate and a winch arranged on the top of the pile hole. The plumb weight is introduced into the pile hole, and the free ends of all the suspension cables are connected with the stabilizing plate, and there is a stabilizing platform under the stabilizing plate, and a three-dimensional laser scanner is installed on the stabilizing platform, and the measurement and control computer It is connected with the CNC winch, the stabilizer head and the 3D laser scanner through cables. The detector in the present invention can perform all-round three-dimensional scanning on the wall of the pile hole, the data collected by it is sufficient and stable, can better reflect the hole diameter and verticality of the pile, is convenient to use, and has high detection efficiency.
Description
technical field [0001] The invention relates to the field of cast-in-place pile construction, in particular to a stable three-dimensional pile hole detector. Background technique [0002] The pile foundation is the key component of the stability of the bearing capacity of the urban subway station structure, and the quality of the hole formation is one of the important factors affecting the quality of the cast-in-place pile. The quality of hole formation is affected by factors such as groundwater, underlying structure, and hole formation operations, which may cause adverse effects such as hole collapse, diameter shrinkage, pile hole inclination, and excessively thick sediment. Collapsing holes will cause the diameter of the pile holes to exceed the standard and produce slag; diameter shrinkage will cause the diameter of the pile holes to fail to meet the standard and affect the bearing capacity. Therefore, the design bearing capacity requirement cannot be achieved; too thick...
