Track structure in tunnel crossing active fault and correction construction method
The invention relates to the technical field of railway tunnel construction, in particular to a track structure in a tunnel penetrating through an active fault and a correction construction method. The structure comprises an inverted arch filling layer, a cushion layer, a spherical hinge rotating body support and a base plate, the cushion layer is arranged above the inverted arch filling layer; the spherical hinge rotating body support is cylindrical and is arranged in the circular groove; the base plate is arranged on the spherical hinge rotating body support; a rotation limiting device for fixing the rotation angle of the spherical hinge rotation body support is further arranged between the base plate and the inverted arch filling layer. According to the track structure, horizontal rotation, vertical rotation and distortion correction are carried out on the track plate, so that the transverse and vertical curve radiuses of the dislocated track are effectively increased, the line of the line track is smooth, and the curve is in smooth transition, thereby meeting the track direction, height and distortion acceptance indexes of the high-speed rail track; therefore, the defect that rail deformation of a conventional high-speed rail line is difficult to adjust and correct after fault dislocation is effectively overcome.
本发明涉及铁路隧道施工技术领域，具体而言，涉及一种穿越活动断层隧道内轨道结构及校正施工方法。所述结构包括仰拱填充层、垫层、球铰转体支座和底座板；所述垫层设置在仰拱填充层的上方；球铰转体支座为圆柱状，所述球铰转体支座设置在圆形凹槽内；所述底座板设置在所述球铰转体支座上；所述底座板与所述仰拱填充层之间还设置有固定所述球铰转体支座旋转角度的旋转限位装置。本发明通过对轨道板进行水平旋转、竖向旋转、扭曲矫正，有效增大错动后轨道的横竖向曲线半径，使线路轨道线路平顺且曲线平缓过渡，以满足高铁轨道的轨向、高低、扭曲验收指标，从而有效解决常规高铁线路因断层错动后的轨道变形难以调节、矫正的缺陷。
