为提高钢轨爬行的测量精度,对钢轨爬行检查方法作了如下几方面的改进。研制了中心桩间钢轨爬行测量器,利用测绳紧靠钢轨的特点,可直接根据测量器刻度读取数值,在隧道
In order to improve the measurement accuracy of rail creeping, the method of rail creeping inspection has been improved in the following aspects. Developed a center crawler track between the piles measuring instrument, the use of rope close to the characteristics of the rail can be measured directly on the scale reading values in the tunnel
