(新春走基层)西南铁路建设春节不停工 超2万名建设者坚守一线

　　中新网成都2月4日电 (刘晓 吴宇)工程车辆来来回回，大型机械精确开挖……春节期间，成昆铁路峨米段、渝昆高铁川渝段、成兰铁路、成自高铁等在建项目现场，依然机具轰鸣，热火朝天，超2万名建设者坚守一线，确保西南铁路建设如期完工。

成昆铁路复线冲刺全线贯通

　　1月10日，首趟复兴号动车组开进了大凉山，成昆铁路扩能改造工程最后一段峨冕段建设迈上冲刺步伐。该段小相岭隧道是全线建设项目中最难最长的一个隧道，为1级高风险隧道，是成都平原连接大凉山最后一个梗阻。

　　春节期间，小相岭隧道内，电钻声焊接声机械轰鸣声交织在一起形成特殊的工程交响乐。428多人坚守，132台设备，争分夺秒进行最后的贯通冲刺，8个作业面全面开工……

　　“今年春节我们全部不放假，平均每天可以推进32米，24小时不停工，分为三班轮换。”项目书记刘乾介绍说。

　　同样，在成昆铁路峨米段铺轨现场，中铁八局近50名管理人员、600余名农民工，春节期间依然坚守工地。

　　他们要在3月份完成燕岗站改便线拨接开通、轨道铺设、T梁架设至老鼻山无砟隧道出口进入峨边南站，工期十分紧张。

　　中铁八局成昆铁路EMZQ-1标项目经理李小伟说：“原本想让大家聚在一起团年的，但是标段工点分散，为避免人员流动、聚集带来安全风险，项目部最终决定将物资发放到工点，让大家各自组织团年。”

一批重点项目进入攻坚阶段

　　2022年，西南铁路的渝昆高铁、成兰铁路、成自铁路、自宜铁路等在建重点项目进入攻坚阶段，这是一场场与时间的赛跑。

　　The Zhongliangshan Tunnel is a time card control project of the Sichuan-Chongqing section of the Chongqing-Kunming high-speed railway. The total length is 4,973 meters. The construction period is planned to be completed in 2023. The builders are racing against time.

Since January 1 last year, in just one year, the construction personnel have excavated more than 1,200 meters.

In order to ensure the progress of the construction, Huang Yongming, the head of engineering technical survey, and the workers all stick to the front line during the Spring Festival this year, set out the line at the site during the day, and instruct the machinery to excavate correctly, and review the measurement data at night to provide a basis for the construction.

　　Zhongliangshan Tunnel not only spans two tunnels, but also passes through difficult problems such as goafs of coal mines, and bad geology such as karst, water inrush, broken sections, and faults are also "grouped to patronize".

To build a high-speed railway with a speed of 350 kilometers per hour in such a complex geological environment, this year, Huang Yongming and the construction staff have often been fighting for 1 cm or even 1 mm.

　　More than 160 Shandong workers stayed at the construction site of the Jinxiu Tunnel within the main urban area of ​​Chengdu.

After the heavy fog warning was lifted in the past few days, they immediately carried out shield construction. This is the largest diameter earth pressure balance shield machine construction tunnel in the country. The travel range will cross the existing operating railway 7 times, and the minimum covering soil thickness is less than 8 meters.

　　In order to ensure that the shield tunnel section of the tunnel is connected by the end of September this year, they accelerated the shield tunneling during the Spring Festival, and simultaneously realized that the construction site of the continuous beam of the main span of the 100-meter main span of the double-line super bridge at the interchange of the project around the city will not be closed during the Spring Festival.

　　The relevant person in charge of China Railway Chengdu Bureau Group Co., Ltd. said that the Chengdu Bureau is fully mobilizing and organizing the construction of railway projects, striving to complete the workload, and focusing on speeding up the Chengdu-Lanzhou Railway, the Chongqing-Kunming High-speed Railway, the Chengzi Railway, the Ziyi Railway, and the Guinan Railway. Customer specialization and other key projects under construction.
