FAQ highway bridge laminated rubber bearings and treatment pathways highway bridges, viaducts city has become a major traffic artery and hub cities, plays an important role in the national economy and people's daily life. Bridge bearings are an important part of the bridge structure, a direct impact on the life and safety of the bridge structure, which, because of its laminated rubber bearing structure is simple, reliable performance, easy installation of replacement, low cost, has been widely used in highway urban bridge construction. But we need some common disease problems in a timely manner in the laminated rubber bearings and timely measures to replace the bearings. Roads and bridges; laminated rubber bearings; processing pathways in this article I will be laminated rubber bearing problems often appear in one treatment, targeted prevention of disease and ensure the normal use of the highway bridge. 1, stone and beams supporting seat bottom support wedge position, size, elevation construction deviation is too large. Stone and beams that support seat bottom support wedge position is not accurate, wide on each side of the seat size is too small, highly branched stone and beam bottom cushion supporting wedge is too big or too small, pad stone top elevation of Construction deviation is too large. Prevention of points: piers, stone and beams supporting seat bottom support wedges respond before construction Surveying be reviewed to ensure the accuracy of its construction control line to meet the requirements, and to conduct technical tests related to construction personnel, in strict accordance with the design of construction and regulatory requirements to ensure that it meets the requirements of construction quality. 2, support cushion stone concrete top surface is not level, uneven, and the lack of strength, not dense concrete, internal voids and other defects, affect carrying capacity. Prevention Important: When installing the application pad stone level of the ulnar side of the mold level, no mold top level should be adjusted in a timely manner. Note that when the concrete pad stone stone on the top surface of the pad were smooth but not calendered, so that the top surface of the concrete pad stone and side molding along the top pick in the same horizontal plane, and if necessary should obtain the consent of the design, to improve concrete grade, C30 to C50 concrete as concrete. Surface of the concrete pad stone cap beams should chiseling parts thoroughly, small square stone concrete pad volume, but must also be a mechanical mixing, non-artificial random mixing. To strengthen concrete tamping, compacting concrete guarantee reliable. (3) support cushion stone and beams supporting wedge insole reinforced through the large gaps or protective layer thickness. Prevention Important: pay attention to the quality of construction stone and beams supporting seat bottom support wedges and other small parts, in strict accordance with design drawings and specifications reinforced install these parts. (4) Individual bearing specification model is not entirely consistent with the design requirements. Prevention Highlights: Supports the procurement approach and transported to the next pad stone ready installation, should carefully review the bearing specifications, type, quantity, to ensure that throughout the bearing specifications, models, the number of full compliance with design requirements. When the construction of a seat is found lacking or specifications, the model does not, the holder is prohibited throughout the random substitution, nor may it be big-generation small, on behalf of the weak to the strong, but not a small generation of large, on behalf of the weak and strong . Location (5) bearing installation, construction deviation direction is too large, or even inverted bearing longitudinal and transverse directions.
