| 防撞墙伸缩缝钢遮板桥梁护栏钢遮板指的是为满意桥面变形的要求，一般在两梁端之间，梁端与桥台之间或桥梁的铰接方位上设置弹性缝。要求弹性缝在平行，笔直于桥梁轴线的两个方向，均能自在弹性，结实牢靠，车辆行进过期应防撞墙伸缩缝钢遮板平顺，无突跳与噪声，要能防止雨水和泥土进入堵塞，简易便利装置。在设置弹性缝处，栏杆与桥面铺装都要断开。钢护栏立柱放样:A、立柱应依据规划图纸进行放样，并以桥梁、通道、涵洞、立交护栏伸缩缝钢遮板、平交等为操控点，进行测距定位，可运用调整段调理距离，并运用防撞墙伸缩缝钢遮板分配办法处理距离零头数B、为精确放样和确保护栏的线形，隔段进行桩号复核和闭合。 Anti collision wall expansion joint steel shutter bridge guardrail steel shutter is to meet the requirements of bridge deck deformation. Generally, elastic joints are set between two beam ends, between the beam end and the abutment or on the hinge direction of the bridge. It is required that the elastic joint should be parallel and straight to the two directions of the bridge axis, both of which should be free and elastic, solid and reliable. When the vehicle is running, the steel shutter of the expansion joint of the anti-collision wall should be smooth, without sudden jump and noise. It should be able to prevent rain and soil from entering and blocking, and it should be a simple and convenient device. At the place where the elastic joint is set, the railings and the bridge deck pavement should be disconnected. Steel guardrail column lofting: a. the column should be lofted according to the planning drawings, and the bridge, passage, culvert, overpass guardrail expansion joint steel shutter, level crossing and other control points should be used for distance measurement and positioning. The adjustment section can be used to adjust the distance, and the distribution method of anti-collision wall expansion joint steel shutter can be used to deal with the odd number of distance. B. to accurately loft and ensure the linear of guardrail, The pile number is checked and closed every other section. |
