Small changes in environmental conditions in the short term, it is usually in the daily inspection remove it. However, when the results of the comprehensive determination of periodic inspection, weather conditions, the bridge features steel truss bearing status has become necessary items. Special examination should be based on damaged condition and the nature of bridge bearings, bearing steel grid using field test equipment and other auxiliary test checks bearing steel grid to analyze the status quo, forming a conclusion. Steel truss bearing special inspection report shall include the following main elements: general overview of inspection, including the basic situation of a one-way bridge bearing seismic activity GKQZ type ball bearings, inspection organization, time, Beijing and inspection process and so on. Steel truss bridge bearing bearing describe the current state of technology, including project and methods sausage investigation, testing and inspection, testing and analysis of data and evaluation of the technical condition of the bridge abutment. Detailed description of the extent of damage and the cause of the examination site and proposed bridge bearing structural parts or the whole of repair, strengthen or suggestions motion replacement. Typical defects and diseases and diseases of the photo and description. Application of professional standard terminology bidirectional ball bearing slide GKQZ type earthquake, indicating the site of the defect described defect condition, type, nature and scope. Causes the function to reduce bearing steel grid is very complex, it should accurately grasp the reason for the change before making repair extremely important GKQZ seismic steel ball bearing type repair method chosen for the reason, same time, different repair method sometimes bring to other structural parts of the adverse effects, iconic, not only depends bearing steel grid itself, the impact is more to be produced under other steel truss bridge abutment and structural parts of the comprehensive consideration of the whole bridge case to select patches sewn method. Steel truss bearing repair method, according to their location and extent of damage, and can be divided into the replacement, repair, reinforcement and protective coating, these patches are described below is a method to replace bridge bearings, bridge bearings year after year in the course of aging GKQZ type seismic ball bearings, steel truss seat itself and the base will be partially damaged or severely damaged, while the beam instead of the top acts of the core holder worse is often the case, called to replace them all in to replace them all in recent years, there will be replaced by rubber bearing steel bearing practice, so it should be noted bearing steel grid do not have too much compression, but also pay attention to the order of replacement and construction accuracy problems.
