Which bridges need inspection? What are the routine "physical examination" items for these bridges?
Many people ignore the inspection of houses and municipal buildings. As more and more buildings have experienced various quality problems in recent years, relevant departments have begun to strengthen the inspection of buildings. . Bridges are municipal buildings. For some bridges that have been in use for a long time, they need to be inspected more. Do you know which types of bridges need to be inspected? And what are the common bridge inspection contents? So next, Xiaohan will take everyone to have a brief understanding.
1. Which types of bridges need to be inspected?
1. Bridges that have serious disease problems but have not been maintained for a long time;
2. Bridges with worrying safety levels and no safety certificates;
3. Bridges that have experienced many accidents and need to improve their safety performance;
4. Bridges with increased load requirements;
5. Major changes in use functions bridge.
2. What are the common bridge inspection contents?
When inspecting a bridge, there are many items that need to be inspected. Only with a comprehensive understanding of the bridge can the safe passage of the bridge be ensured.
1. Bridge quality condition inspection
Not only does it need to check whether there are obvious flaws or quality problems in the appearance of the bridge, but secondly, it is also necessary to judge the bridge by inspecting the internal structure of the bridge. quality level. When using specialized instruments to test the quality of a bridge, it is necessary to systematically and comprehensively understand the various indicators of the bridge. The test results of the bridge quality condition are important indicators for measuring the quality level and safety performance of the bridge. The test results are also important. meaning.
2. Bridge defect detection
The appearance of many bridges has serious defects, especially some bridges that have been used for many years but have not been properly maintained. The piers of such bridges , bridge deck, internal lighting equipment and other aspects may have problems. When we check the bridge defects, we need to check many aspects, such as: appearance inspection of the bridge; inspection of the stability of the bridge bearings; appearance inspection of the bridge piers; Inspection of bridge foundation; inspection of internal structure, etc.
3. Load test
More than ten years ago, most bridges could meet the traffic needs at that time. However, with the increase in the number of private cars and the increasing number of people going out, As the frequency increases, the load capacity of many existing bridges cannot meet the current demand for bridge use. We need to conduct load tests on bridges. Bridges whose load test results do not meet the standards need to be reinforced in a timely manner or some internal components must be dismantled and rebuilt to ensure reinforcement. The reconstructed bridge can meet the current traffic requirements. For bridges whose load capacity is obviously not up to standard, it is necessary to calculate the cost difference between demolition, reconstruction and reinforcement and maintenance, and select the best solution after comprehensive consideration of various aspects.
Many bridges have many problems due to their long service life. For this type of bridges, bridge inspection is urgent. When inspecting bridges, there are many key inspection indicators that cannot be ignored. Yes, only if all the results of the bridge inspection meet the requirements for the use of the bridge, this type of bridge can continue to be put into use. Otherwise, it needs to be modified and reinforced before it can continue to be used.
