Electromagnetic sensing principle based inspection component of concrete reinforcement detector

Abstract

The invention provides an electromagnetic sensing principle based inspection component of a concrete reinforcement detector. The inspection component is manufactured from organic glass. The inspection component is manufactured by the steps of manufacturing an organic glass component, and manufacturing a standard reinforcement bar. The organic glass component is manufactured by the steps of a) blanking, namely, cutting into blocks as requirement through a portable electric saw; b) roughly planing, namely, roughly planing the organic glass blocks through a numerical control milling machine, wherein the rough planing precision is +/-0.0.2mm; c) drilling a hole, namely, drilling reinforcement preset aperture in the roughly planed organic glass plate through a drilling machine according to the design aperture position, wherein the drilling precision is +0.02mm; d) polishing the aperture, namely, polishing the aperture through a zinc bar and a polishing machine, wherein a nylon fabric coils the zinc bar, and polishing wax is coated on the nylon fabric, and about 0.02mm diameter is increased after polishing; e) polishing the surface, namely, polishing the organic glass surface through a diamond polishing machine. The standard reinforcement bar is manufactured by the steps of milling an HRB400 reinforcement through a machine tool, wherein the processing precision is -0.02mm, the length is 20mm less than that of the organic glass, and 10mm is reserved in two ends of the standard reinforcement bar; sealing through curing glue.

Description

technical field [0001] The invention belongs to the field of traffic measurement, and in particular relates to a concrete reinforcement detector inspection component based on the principle of electromagnetic induction. Background technique [0002] Most of the concrete steel bar detectors are based on the principle of electromagnetic induction. The probe emits electromagnetic signals, and the steel bars in the protective layer generate a secondary induction magnetic field, which is received by the probe and processed by the instrument to obtain the measured value of the protective layer thickness or steel bar diameter. It is inspected by a concrete steel bar detector inspection component based on the principle of electromagnetic induction. [0003] At present, the value of the concrete steel bar position detector can only be calibrated by comparison or inspection components, but the uncertainty of the measurement results cannot be effectively controlled, and the traceability...
