Pendulum column bearing steel grid is accurate relative position of the components, the force is uniform. Whether roller bearing steel grid rollers allowed crawling, skewed. Rocker shaft bearing steel grid is tilted. Note concrete steel pendulum cast concrete columns bearing steel grid or without peeling elastic hinge support, cracking, exposed tendons and steel with or without corrosion. In regular testing stage, steel grid bearing defect location, type, nature, scope, quantity and description of the extent of the situation carefully, the typical defects and provide photos and images. More requirements for special bridge inspection report should clearly explain the reasons to check. Special investigation. The so-called special survey is to be inspected regularly, after regular inspection, bearing steel grid should be based on the status and nature of the damage for dictation specific bridge or steel grid bearing elastic support, the use of instruments to coordinate awakened site testing, load test Other auxiliary test machine, when a detailed investigation conducted by the inspection, repair method determines emergency goods through special investigations and to obtain information on two patches designed to investigate. Furthermore, the survey items bearing steel grid inspection work can include environmental conditions, traffic elastic support damper characteristics and bridge abutment MI status. Deformation or rupture of the main bolt, bolt strength or lack of good material. Not long enough or screws into the anchor well. Bear reaction force insufficient stiffness of anchor bolts fatigue. Long-term repeated action live load fatigue. Although difficult to find in appearance bearing changes, monopile sliding parts to wear or material aging performance degradation may mount reason, in this case, bearing steel grid should also work to do it too an appropriate judgment, the general standard shown below. Degree bearing steel grid survey quite fast. As the administration or management of the bridge, you must stand by the extent of damage to the steel grid survey, and the results of the survey, consider the characteristics of the bridge connection structure, purpose and scale back its elasticity necessity patched grid bearings, repair or strengthening method is necessary to make the right judgments, steel truss bearing damage inspection program to determine the work process flow. Steel truss bearing damage assessment procedures, assessment of damage on bridge bearings procedures currently curing specifications for highway bridges and culverts bearing function has a relatively clear evaluation criteria. In China's railway sector has assessed standard railway bridge and tunnel building.
