Cctv news(Reporter wanglili): In less than 8 minutes on average, there will be a series of "iron dragons" full of goods whizzing by in the Jinci Tunnel in the southwest of Taiyuan, Shanxi.
As the throat passage of bulk cargo in Shanxi and train transportation between China and Europe, the southwest ring railway line has a total length of 53.64 kilometers, of which more than 20 kilometers are underground tunnels, which pass through many rivers and ditches, and silt and garbage often block drainage ditches.
During Spring Festival travel rush, a group of railway "scavengers" worked in the underground tunnel. They walk 6 kilometers every day, wading through the cold sewage, discharging silt and dredging, and guarding the operation safety of freight trains from south to north.
Martin and his eight workmates, who work in the bridge and tunnel workshop of Taiyuan Works Section of China Railway Taiyuan Bureau, undertake the daily drainage and dredging work of Jinci Tunnel. Walking along the tunnel for a few minutes, experienced Martin stopped following the sound of running water, bent down and fell to the ground, uncovered the concrete cover plate of the drainage ditch next to the line with tools, leaned into the narrow drainage ditch and used a flashlight to check the situation inside.
"The mineral content of groundwater here is particularly high. Just like our kettle, the scale will accumulate thicker and thicker." Martin said that once there is a drainage blockage in the tunnel, if it is not cleaned in time, it will lead to flooding lines and affect driving safety.
Going on for tens of meters, there are sundries floating on the muddy sewage in the ditch, emitting a pungent smell. At this time, Zhang Ligang of the bridge and tunnel workshop of Taiyuan Works Section of China Railway Taiyuan Bureau skillfully put on plastic waterproof clothes, stepped into the sewage that had not passed the calf with his feet, and shoveled the mud into the woven bag with a shovel. When encountering a place that is difficult to dredge, he can only roll up his sleeves, bend down and curl up in a narrow space, and dig out with his hands.
Zhang Ligang said: "If you want to find the blocked drainage ditch in the tunnel, you can only lift the board piece by piece." Although they are all wearing waterproof clothes, biting sewage will still seep into their clothes, and their arms will be swollen and unconscious after a long time.
With the removal of silt and debris, the sewage level began to drop and the water flow resumed smoothly. After a deposition point was cleared, the workers continued to "patrol".

Due to the particularly high traffic density in the driveway, the time left for workers to work is very tight. In addition to racing against time to clear up silt, they also have to avoid speeding trains from time to time.
During their stay in Spring Festival travel rush, they walked 6 kilometers a day, bent over, dredged canals and removed silt, and cleaned up 36 places /15 cubic meters. This seemingly simple work content, everyone has to repeat it hundreds of times, they use a dirty suit, in exchange for the smooth drainage of the tunnel, to ensure the safety of the train.
