Factory reinforcement inspection is an essential step, referring to the detection of the current condition of the factory before reinforcement work is carried out. The price for Nanyang school building inspections is provided, and the safety condition of the main structure of the reinforced factory is directly reflected through reports. It offers reinforcement suggestion plans for the later factory reinforcement project, ensuring the smooth progress of the subsequent reinforcement work.

The factory building requires safety and seismic tests both before and after reinforcement. Prior to renovation, a reevaluation and modeling calculation of the building's structure and load-bearing capacity must be conducted to provide data support and recommendations for the renovation project and plans. After renovation, a review and acceptance of the renovation status and drawings are necessary to ensure the quality of the renovated factory and its requirements. Factory strength testing mainly includes safety and seismic tests. Factory safety testing involves: investigating, on-site inspections, structural analysis calculations, and assessing the factory's safety. It is primarily applicable to factories with identified safety hazards, dangerous signs, or those requiring safety grade assessment. Factory seismic testing refers to: This test is used for assessing the seismic capacity of factories in use and those planned for renovation. It mainly involves inspecting the current structural condition of the factory, investigating the renovation plans and future usage, and evaluating the factory's seismic performance according to prescribed seismic defense requirements.

Crack Depth Detection

Crack depth detection is suitable for ultrasonic testing. Depending on the relationship between the crack depth and the thickness of the component being measured, as well as the testable surface conditions, methods such as single-side flat measurement, double-side oblique measurement, and drilling cross-measurement can be chosen. When there is only one measurable surface at the crack location of the structure, and the estimated crack depth is not greater than half the thickness of the component or 500mm, single-side flat measurement can be used. It is required that both sides of the crack location have clean, flat, and crack-free concrete surfaces for testing, with the width of the testable surfaces on both sides being at least as wide as the estimated crack depth. By measuring the sound across the crack and the concrete sound velocity, the crack depth at the measurement point can be calculated.

When the crack part of the structure has two mutually parallel test surfaces, double-sided penetration oblique seams can be used to determine whether the relative crack in the component constitutes a through crack. Under the condition of ensuring that all measurement lines have the same distance, inclination angle, and testing system, the measurement lines across and not across the crack section are compared. Based on the change in acoustic parameters, the crack depth and whether it penetrates the cross-section are determined.

The drilling method is suitable for large concrete volumes, predicting crack detection depths of 500mm or more. Drill test holes on both sides of the cracks, and use radial vibration transducers to perform related detection point by point from top to bottom within the holes. Plot a depth-amplitude graph, where the amplitude reaches a high level and becomes basically stable, corresponding to the crack depth.
