What is the bridge inspection?
Bridge Inspectorate is a thorough evaluation of the bridge with engineering specialists for safety purposes. Regular bridge inspections are required by law in many countries, while local regions can have their own similar requirements. These requirements often apply only to bridges that mediate vehicles such as cars or trains. The inspection will focus on the structural integrity of the bridge, drainage and other problems that can affect safety. If the structure fails to check the bridge, it can be closed for maintenance, renovation or even demolition and reconstruction if necessary. They cross water formations or sharp surface tendencies, sometimes stretching distances that can be measured in kilometers or kilometers. Many people carry thousands of vehicles a day and must be able to withstand extreme temperatures or weather conditions. This includes complicated integration engineering principles such as expanding metals and fatigue, weight distribution and traffic formulas. In the United States only more than 100,000Bridges with high operation of regular bridge inspection. States have their own regulations, some of which require more frequent inspections of local authorities. The inspection process also contributes to accumulating data that can be used to determine security standards at national or even international level.
The bridge inspection is carried out by a specially trained team of engineers. These engineers examine a number of details that can contribute to the safety of the bridge. In addition to the above factors, they also check the voltage and metal voltage, joints and connections and lighting. Railing, road width and even Quality painting also checked ITY, which can protect against rust and deterioration. Similar principles apply to train bridges and even some pedestrian bridges that are subject to inspection. Despite all these measures, the accident is still occurring.
on 1. August 2007 in Minneapolis in Minnesota collapsed bridge that passedthe operation of the bridge to the main northern-south highway; 13 people were killed and others were injured. Subsequent investigation revealed that the previous bridge inspection gave the bridge among the lowest acceptable assessments. Officials who were aware of this evaluation were not sure how to proceed because engineers found that the renovation of the bridge would further weaken it. The cause of the accident was previously an unknown design error, undetected by repeated inspections, combined with overweight building equipment that carried out the bridge maintenance. The incident led to the national review of the security policy and the inspection of the bridge.
