　　标段控制性工程——五华特大桥最后一段连续梁顺利合龙，下部主体结构竣工；桥头铺、油岭坝1号两座隧道施工克服复杂围岩条件先后贯通……1月24日，梅龙铁路施工建设接连传来喜报。岁末年初，中铁二十五局1000余名建设者奋战在革命老区、世界客都——广东梅州，只为这条数百万老区人民翘首以盼的铁路动脉早日开通。

　　梅龙铁路位于梅州、河源两市境内，全长95.6公里，建设工期4年，是广东省首个自行投资建设的时速350公里高铁项目，也是支撑梅州、河源两市融入粤港澳大湾区国家发展战略的重大基础设施项目。

　　22日夜里10时许，五华县城内灯火阑珊，多数人准备躺进温暖的被窝中，此时的五华特大桥上却是灯火通明、人声鼎沸。许喆早早登上桥面，指挥混凝土浇筑施工，他们要赶在凌晨以前完成五华特大桥最后一块连续梁浇筑，确保大桥顺利合龙。泵送混凝土、振捣、抹面、泵车移位……这套看似简单的流程要在大桥上重复演绎10余次，但作为中铁二十五局梅龙铁路4标项目部现场施工负责人，许喆既要统筹协调现场，又要盯控每一个细小环节，不能出现丝毫马虎。经过35名工友的共同努力和2个小时的紧张作业，桥面被严丝合缝地连成了片。“最后一段连续梁完成合龙，五华特大桥下部结构竣工！”许喆高兴地说道。

　　许喆告诉记者，中铁二十五局承建的梅龙铁路4标段全长29公里，其中五华特大桥是全线控制性工程、最长桥梁。作为全线架梁的起点，该桥先后跨越S228省道、乌陂河等多条道路及河流，贯穿人口密集城镇，施工难度大、安全风险高。项目部在落实各项疫情防控举措的基础上，采用三班倒方式开展施工，既保证作业的连续性又保证施工人员作息，他们还在安全风险源处安装视频监控系统，对现场作业情况进行远程监控，确保桥梁施工顺利完成。

　　At present, the builders have completed the construction of all the piers and continuous beams of the Wuhua Bridge before the Spring Festival.

　　Tunnel penetration on schedule is another key to ensuring beam erection across the line.

Affected by the previous epidemic, some areas of Wuhua County implemented epidemic control, which affected the supply of project materials and the lives of employees.

To this end, the project department formulated an epidemic prevention and control plan, distributed epidemic prevention materials, arranged 4 nucleic acid tests for all employees in 7 days, released the latest epidemic-related news in a timely manner, popularized prevention and control knowledge, soothed employees' emotions, eliminated panic, and actively responded to the outbreak of the epidemic. The adverse impact of the project has achieved the goal of no lag in the construction progress and "zero infection" of employees.

　　On January 23, the Qiaotoupu Tunnel and the Youlingba No. 1 Tunnel were opened on the same day. The lengths of the tunnels are 510 meters and 250 meters respectively. Although they are short-distance tunnels, the construction is faced with complex geology such as broken rock mass and fully weathered steep slopes.

　　At the construction site, a young face is active.

His name is Li Dinghui, from Jiujiang, Jiangxi Province. He is a "post-95" technician. He has just been transferred here from the recently completed Ganshen high-speed railway. He is responsible for organizing the construction of the tunnel face and the second lining inverted arch. He has four years of high-speed railway construction experience. Let him gradually grow into a unique technical staff.

"This is the 12th tunnel that we have passed through the lot, and there are still 7 tunnels that will be passed through. Our tunnel work district director Wu Jia has not been home for two Spring Festivals. I will stay and fight with him this year!" Li Dinghui said arrive.

　　It is reported that after the completion of the Meilong Railway, it will take up most of the passenger flow from Meizhou to the Pearl River Delta region. By then, the transit time from Meizhou to Guangzhou will be shortened from the original 6 hours to 1.5 hours, which will help speed up the construction of the Pearl River Delta, eastern Guangdong and Meizhou. , Heyuan high-speed railway channel, improve the layout of high-speed railway network in Guangdong Province, and promote regional economic development is of great significance.
