一、病害的现状与分析 1.缓行器部分钢轨三次折断,钳口变形,车辆通过时左、右摇摆,钳口磨损超限。检查丈量入口道岔理论中心至钳口为9.277m,比设计规范规定10.437m少1.16m,未做过渡段,未设护轮轨,不能保证车辆直线进入钳口,缓行器有1.16m要克服车辆向心力的冲击,致使钳口变形。 2.基础部分整体道床开裂、下沉,钢筋混凝土枕与整体道床脱离,尤以第1、4节较为严重。虽经四次抬道,用高压风将瓜米石送入整体道床 First, the status and analysis of the disease 1. Three parts of the retarder broken rail, jaw deformation, vehicle left and right swing, jaw wear overrun. Check and measure the entrance switch center theory to the jaws for the 9.277m, less than the design code 10.437m 1.16m, no transitional section, there is no wheel guard rail, can not guarantee the vehicle straight into the jaws, the retarder has 1.16m to overcome the vehicle The impact of centripetal force, resulting in deformation of the jaws. 2. The basic part of the overall ballast bed cracking, sinking, reinforced concrete pillow and the overall separation from the road bed, especially in Section 1,4 more serious. Although after four lift road, with high-pressure wind will melon stone into the overall track bed
