Recently, the Kampung Siam Tunnel No. 3 of Malaysia’s East Coast Rail Link (ECRL), constructed by China Communications Construction Company (CCCC), was successfully completed as scheduled.

“This 1.32-kilometer-long tunnel is the 25th of the 40 tunnels in the ECRL project to complete excavation, marking that more than half of the tunnel construction is now finished,” stated Kong Qi, General Manager of CCCC’s ECRL project company. Located on the western extension of the ECRL, the completion of Tunnel No. 3 signifies another significant milestone in the overall tunnel construction process.
The ECRL, stretching 665 kilometers, begins in Kota Bharu on the east coast and runs across the states of Kelantan, Terengganu, and Pahang before turning westward to connect to the Klang Valley on Malaysia’s west coast.
The construction of Tunnel No. 3 presented significant challenges due to its shallow depth, poor surrounding rock conditions, and location in water-rich areas. The tunnel faced substantial seepage along with geological issues such as collapses, rockfalls, unbalanced pressure, soft rock, and landslides. Additionally, large-scale deforestation in the area was avoided to minimize environmental impact. To address these challenges, the construction team employed mechanical excavation and the drill-and-blast method to tunnel through completely weathered sandstone and mudstone layers. Utilizing Chinese engineering techniques, they constructed a double-track railway tunnel with an average height of 14 meters and a width of 13 meters, meeting the standards for both passenger and freight transport.
Tan Sri Zuki Ali, Chairman of Malaysia Rail Link, stated that the breakthrough of Tunnel No. 3 also signifies the completion of all tunnel excavation work for Sections A and B of the ECRL. “Throughout the process, Chinese engineers safely excavated 167,830 cubic meters of soil and rock, minimizing surface impact. This achievement paves the way for the tunnel’s civil engineering work to be fully completed by April 2024,” he said.
“一带一路” 造福世界，中企承建马东铁路隧道施工完成过半

近日，中国交建承建的马来西亚东海岸铁路甘邦暹罗3 号隧道按原定计划顺利贯通。
马东铁路
“这座全长 1.32公里的隧道，是马东铁路项目全部40座隧道中完成挖掘工程的第 25 座隧道，标志着隧道工程完成过半。”中国交建马东铁路项目公司董事总经理孔琦说，3号隧道位于马东铁路向西延伸处，这座隧道的成功贯通，是整个隧道建设中又一个重要里程碑。
全长 665公里的马东铁路起于东海岸的哥打巴鲁，将穿越吉兰丹州、登嘉楼州和彭亨州，然后向西转弯，连接马来西亚半岛西海岸的巴生谷。
3号隧道建设最大特点和难点是埋深浅、围岩差，且围岩多位于强富水区、富水区，隧道内渗水大存在塌方、落石、偏压、崩塌、软弱围岩等诸多不良地质现象，同时避免在该地区进行大规模的森林砍伐。为了达到上述效果，3号隧道施工团队采用机械开挖和钻爆法施工，穿越完全风化砂岩、泥岩层，用中国技术打造出一条平均高度为 14米、宽度为 13米，满足客货共线双线标准的铁路隧道。
马来西亚铁路衔接公司主席丹斯里祖基阿里表示，3 号隧道的成功贯通，也标志着 马东铁路A 段和 B 段所有隧道挖掘工程圆满完成。“中国工匠在整个过程中安全地挖掘了 167,830立方米的土壤和岩石，并最大程度地减少了地面影响，这也将有助于该隧道的土建工程能在 2024 年 4 月前完全完成。”
