Changjiu Intercity Railway Replaces rail Tracks

Replaces rail

In the early morning of September 24, in the section between the K23 line of the Changjiu Intercity Railway and the De’an Intercity Yard, more than 100 operators of China Railway Nanchang Bureau Group Co., Ltd. carried out section-by-section steel rail replacement construction here to ensure the “October” Golden Week. During this period, the train runs safely and smoothly.

The Changjiu Intercity Railway runs through the northern Jiangxi Plain and is a major railway artery connecting Jiujiang and Nanchang. It also connects Wujiu, Shanghai-Kunming and other railway lines. The traffic flow is dense and the transportation is heavy. The rails of the line equipment have high bearing pressure and serious wear and tear. Timely replacement can ensure that Driving safety.

At 1:40 in the morning, with the issuance of the construction work order, the workers quickly picked up the equipment and materials and entered the construction site. Workers wear small headlights, remove bolts, replace rubber pads, saw steel rails, etc.

About 20 minutes later, with the sound of a loud whistle, the rail car slowly drove from a distance to the construction site and stopped precisely at the designated location. The workers in charge of the rail-changing equipment quickly surrounded them, quickly put down the two rail-changing trolleys from the rail car and moved them to the rails.

Then, the workers in charge of lifting the rails lifted the old and new rails with a rack press one after another, and moved them to the rails. In turn, feed them into the bayonet of the rail-changing trolley. With the cooperation of the workers, the old and new rails are “threaded” like “noodles” on the rail-changing trolley.

In the early stage of construction, the workshop carefully carried out risk research and judgment, optimized and formulated construction safety measures, carried out special training for on-site construction personnel, and detailed each operation item during the construction process to ensure that all construction is completed within the specified time. Task.

After 210 minutes of intense construction, the workers successfully completed the task of replacing the 500-meter long rail, and the new and old rails completed the “change of guards”. Work items such as welding, rail stretching, and locking fasteners were also completed one after another. After the on-site construction person in charge confirmed the line status, the line was opened on time.
