Abstract

The invention discloses a stable type three-dimensional pile hole detector which comprises a measuring and controlling computer, a numerical control winch, a stabilizing plate and a winch frame arranged on the top of a pile hole. At least three hanging ropes are arranged on the numerical control winch, and led into the pile hole through a plumb bob after passing by the winch frame. The free ends of all the hanging ropes are connected with the stabilizing plate. A stability increasing pan-tilt is connected with the lower side of the stabilizing plate. A three-dimensional laser scanner is installed on the stability increasing pan-tilt. The measuring and controlling computer is connected with the numerical control winch, the stability increasing pan-tilt and the three-dimensional laser scanner through cables. By means of the detector, all-directional three-dimensional scanning can be conducted on the wall of the pile hole, data collected by the detector is sufficient and stable, the diameter and perpendicularity of the pile hole can be well reflected, use is convenient, and detecting efficiency is high.

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 a key component of the stability of the bearing capacity of the urban subway station structure, and the quality of the hole 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 excessive sediment thickness. Hole collapse will cause the diameter of the pile hole to exceed the standard and produce sediment; diameter shrinkage will cause the diameter of the pile hole to fail to meet the standard and affect the bearing capacity. Therefore, the requirements of the design bearing capacity cannot be achieved; too thick se...
