Research on the Subsidence Remediation Technology of Monolithic Track-bed for Railway Loading and Unloading Stations
This study focuses on the uneven settlement of the roadbed in the ordinary integral track bed and small climbing car inspection pit section of a railway loading and unloading station,which leads to geometric unevenness exceeding the limit of the line.Based on the statistical data of track unevenness and the current situation of fasteners and sleepers measured on site,the causes of the disease are analyzed.It is proposed that the ordinary integral track bed section with a settlement not exceeding 30mm can lift the line by improving the fastening iron pad and adding a height adjustment pad.The ordinary integral track bed section with a settlement greater than 30mm can lift the line by resetting the short sleepers,and the small climbing car inspection pit section can replace the adjustable double track fasteners for settlement remediation.This plan is fast and efficient in rectification,with minimal impact on loading and unloading operations in the petroleum plant area.Similar technical experience can provide reference for the rectification of settlement defects in ballastless tracks in stations.
