In September, the temperature of Changchun plummeted, but at the construction site of the rail transit line 3 rail line of the Anti -Qianjin Street and the satellite road at Chaoyang District, the machine bangs and the number of sounds were intertwined and staged another hot. At the busy scene, nearly a hundred builders who were conducting sieve and supplementing operations opened the prelude to the centralized renovation of rail transit lines with hard sweat.

As early as September 14, the Changchun Rail Transit Group released the adjustment of the operation section of the rail construction part of the operation section, which was prepared for the construction. Yesterday morning, at the construction site, the reporter saw nearly a hundred workers lined up along the front line. As the construction order was issued, the puppets and mechanical sounds suddenly sounded along the track. The builders quickly entered the operating position in accordance with the plan, and carried out line renovation in a rhythmic manner.

"Whether the track needs to be renovated is depending on the aging of the line, the degree of fatigue, and the damage of the damage." The site builders introduced while the construction was introduced. Due to the long operation time, the lines of the rail transit line 3 Reduce the comfort and safety of ride. At the same time, the repeated impact of the train for many years has caused the tunnel to break, which has gradually lost elasticity and drainage performance, and the phenomenon of "board knots" occur. The centralized renovation is to concentrate a large number of manpower and professional machinery to clear the lines, sieve out the dirty soil at the bottom of the lane, drainage performance of the passage bed, restore the elasticity of the lane, and ensure the safety of the train. In addition, the flat intersection of the line will also be transformed, and the rails along the line will be polished.

"Insufficient space in the station is not enough, large -scale clear sieve cars cannot be launched. In order to ensure the smooth progress of the construction, we cooperate with each other in a group and manually clear the screen." A builder introduced it while demonstrating, and I saw a tap of iron tunnel tie tie tie tie. With the iron chain, one person dragged the iron chain, and one was responsible for digging. The stone pheasant under the pillow was dug together with the mud and the fragmented soil. Spit out the "black dirt. In order to improve the efficiency of clearing sieve, the builders have changed their class and continuously construction to ensure that the construction is completed as scheduled.

The reporter saw in the "Rail Transit Line 3 rail line line line line line line line line 3, supplement, line optimization and base standards, logo logo production installation, road -based freezing damage, and poor drainage project bidding announcement" this time The renovation includes a number of content, which has both the entire line bed clearance, supplementation, and mixing, as well as deepening or new construction of the drainage ditch, as well as flat crossing, overall lane beds, cross -aisons in the stations Newly built and so on. Many citizens have stated that they look forward to realizing "old appearances for new appearances" as soon as possible and return to the convenience of citizens to travel.
