莲花山隧道管线铺设主线焊接顺利完工Lianhua Tunnel Mainline...

2024年6月29日，德平科技承揽的莲花山隧道管线铺设主线焊接顺利完工。

On June 29, 2024, the welding of the mainline of the Lianhuashan Tunnel pipe laying contracted by Deping was successfully completed.

莲花山隧道是粤东天然气主干管网惠州-海丰干线项目的一部分，位于广东省惠东县和深汕特别合作区相交之处的莲花山森林公园腹地，全长5.3公里，为岩质、特长隧道。由于地形起伏大、山体坚硬、山涧巨石密布等原因，它是国内迄今为止距离最长、工况最复杂、施工难度最大的天然气隧道。

Lianhuashan Tunnel is part of the Huizhou-Haifeng mainline natural gas pipeline network project in eastern Guangdong Province. It is located in the heart of Lianhuashan Forest Park at the intersection of Huidong Countyand the Shenzhen-Shantou Special Cooperation Zone, with a total length of 5.3 kilometers, recognized as a rock-type, extra-long tunnel . Due to the undulating terrain, hard mountains and dense boulders in the mountain streams, it is the longest distance, the most complicated working condition and the most difficult natural gas tunnel in China so far.

在项目筹备期，德平面临的最大的难点是施工方案的选择:如果在隧道内先进行主线焊接，后续管墩的施工无法按施工规范进行操作；若先行管墩施工，如何跨越众多管墩进行运管、布管、管道对口、自动焊操作，又是一个大难题。

In the preparatory period of the project, the biggest difficulty faced by Deping was the choice of construction scheme: If the main line welding was carried out first in the tunnel, then subsequent pipe supports could not be built in full compliance with the consturction specfication; if all pipe supports were carried out first, how to cross the many pipe supports along the tunnel for pipe transportation, laying, alignment and auto-welding, it led to another big problem.

鉴于此，德平科技为隧道施工提供了创新的解决方案，设计研发了一整套隧道施工专用运管、对口及焊接系统，为莲花山隧道顺利打火焊接奠定了坚实基础。德平隧道焊接方案可以概括为： 1. 管墩建造：钢筋笼基座，锚杆固定，水泥浇筑 2. 运管 3. 对口：横移平台上下左右调整管口位置，满足焊接错边要求 4. 管道自动焊。

In view of this, Deping provided innovative solutions for tunnel construction, designing and developing a full set of specialized pipe transportation, alignment and welding systems for tunnel, which laid a solid foundation for the smooth welding of the Lianhuashan Tunnel. The welding solution of Deping could be summarized as follows: 1. Pipe support construction: rebar cage base, anchor fixing, cement pouring 2. Pipe transportation over pipe suports 3. Alignment: Traverse platform up and down, left and right to adjust the position of the pipe end to ensure good hi-low effect 4. Pipe automatic welding.

面对在施工过程中出现的各种的技术和环境等难题和挑战，德平团队靠着严谨的态度，缜密的思维给出一个个负责任的解决方案，打赢了一场场的攻坚战，获得承包方和业主的高度认可和尊重。

Faced various technical and environmental problems &challenges arised during the construction process, relying on rigorous attitude and meticulous thinking, Deping's team give responsible solutions, win one battle after another, gain high recognition and respect from the contractor and the project owner.
