Bearing steel grid conduct regular checks of traffic restrictions in principle. Always check the bearing steel grid using visual methods can also be measured with simple tools, will soon fill in the bridge table, always check the discipline, steel grid bearing the scene you want to check the level of the defect types of projects. Shareholders and defects scope and maintenance workload, propose appropriate measures to protect minor repairs, regular inspection of the bearing seat main possessions there is an obvious design flaw grid bearings, bearing steel grid is flexible, the amount of displacement is normal, Always check some bearing steel grid can once every quarter, if bearing steel grid technology development in poor condition and hinge defect mow, you should shorten the inspection cycle. Regular inspection, the so-called regular inspection once a year is twice the goods, shall not exceed three years, aimed to conserve and repair plans next year to provide information. Generally in the road along the bridge inspection program carried out. Mainly through the measuring device to investigate determined. Because when steel grid bearing easily damaged parts, check in often difficult to be visually inspected, and therefore should be treated as regular inspections focus on checking the site, the type of material used in steel grid bearing more rubber, PTFE plate, reinforced concrete, etc., especially rubber and other polymer materials relatively short life span, especially the major aging problem should regularly check. Are steel grid bearing operating normally. Sliding surface or rolling surface corrosion of the main reasons for the deck, defense, poor drainage, causing water to enter the sliding surface or rolling surface corrosion. When the hinge and roller cracking the main reason, such as to limit the transverse components located in the center of the hinge or the rollers, while relying too close if it will produce cracks. Crack and fall off the roll axis, due to shrinkage of concrete, creep displacement of more than design, aging and cracking, aging and cracking of rubber bearing steel grid bearing the main beam chassis construction or bad steel truss supports, overly compressed position in individual cracks. Bearing steel grid strict quality control process causes early aging of rubber, rubber layer cracking, spalling. Lifting means deformation, mainly because of the deformation floating means hands over the role of the complex bridge design to withstand the force and displacement of the deformation. Deformation limit device, the deformation of the main stopper, steel grid bearing selection and arrangement of steel truss bearing inappropriate contraction of the concrete bridge, creep generate additional shrinkage. Construction error generated during deformation, the same support line set up multiple steel grid bearing, due to the gap between the upper and lower transverse bearing inconsistent concentrated force acting on a bearing and deformation. Prestressed concrete bridge of the Bay Bridge or the occasion, because of the tension caused by the compression volume control is not good, displacement restrained steel grid bearing upturned deformation.
