The invention discloses a steel rail detection method for railway construction. The method comprises the steps that S1, detection preparation is conducted, specifically, a detection vehicle is placed on a steel rail, a detection block is connected with the steel rail in a clamped mode, a contact block is connected to the top face of the steel rail in an overlapped mode, and a first rotating rod and a second rotating rod are located on a same straight line, so that follow-up detection is facilitated; and S2, primiary detection is conducted, specifically, balls slide along the top surface of the steel rail, when the balls meet a deformation position of the steel rail in the vertical direction, the position of a liquid level plug in a liquid level pipe is changed, and the deformation degree and position of the steel rail are known. According to the invention, the deformation degree of the steel rail is determined by a deformation detection assembly, the internal damage condition is detected by a flaw detection assembly, the detection range is narrowed, the detection precision is improved, deformation and internal flaw detection are carried out in a centralized manner, the operation steps are simplified, and a pretreatment auxiliary assembly can play an auxiliary role in the detection of the deformation detection assembly and before the detection of the flaw detection assembly, so that the detection precision and efficiency are further improved.

    本发明公开了铁路施工用钢轨检测方法S1:检测准备:将检测车放于钢轨上,检测块卡接钢轨,接触块搭接于钢轨顶面,第一转动杆和第二转动杆处于同一直线上,方便后续检测,S2:初步检测:滚珠沿着钢轨顶面滑动,在遇到钢轨竖直方向形变位置时,液位管内的液位塞位置变化,根据变化程度,得知钢轨的形变程度和位置,本发明由变形检测组件确定钢轨形变程度,再由探伤组件检测内部的损伤状况,缩小检测范围,提高检测精度,形变和内部探伤集中进行,简化了操作步骤,预处理辅助组件对在变形检测组件检测中和探伤组件检测前均可起到辅助作用,进一步提高检测精度和效率。
