中新网宜昌9月30日电 (郭晓莹 董晓斌 秦明硕)随着“最后一爆”顺利启动,作为施工准备试验工程的三峡枢纽新通道先行开挖区30日完成全部爆破开挖作业,为后续高压输电线路迁改、船闸主体工程全面施工创造有利条件。

三峡水运新通道工程是三峡工程之后长江干线上集水利、航运、生态等功能于一体的最大综合性工程,由三峡枢纽新通道和葛洲坝航运扩能两部分组成。其中,三峡枢纽新通道位于已建三峡船闸北侧,规划新建双线连续五级船闸。建成后,三峡枢纽将形成四线船闸加升船机格局,年双向总通过能力达3.36亿吨。

先行开挖区正是三峡枢纽新通道上游引航道末端的一段。作为项目单独实施的先导板块,先行开挖区同时承担着工程实施与技术试验双重使命,被称为三峡枢纽新通道的“先遣队”。

先行开挖区是一座功能完备的巨型综合试验场。近一年的建设过程中,施工单位对施工组织、资源调配、安全管控和质量验收进行了全要素实战检验,为后续大规模、标准化施工积累了现场经验。

据介绍,先行开挖区率先完成的935米上游引航道作业面,底高程达到137.5米,将专门作为部分高压输电线路迁改新走廊。待线路完成迁改后,原有部分区域施工安全限制得以解除,为后续主体工程高强度爆破作业创造前提条件。

记者从三峡新通道公司了解到,先行开挖区爆破开挖作业的顺利完成,为整个新通道工程筑牢了技术、装备、管理三重根基,其积累的所有实测数据和施工经验,将贯穿后续建设全过程,为工程高质量建设提供坚实支撑。

20 years of waiting! Provincial Route 76 from Caotun to Fangyuan is open to traffic, saving 20 minutes on the journey

The 20.8-kilometer west extension of Provincial Highway 76 (Caotun-Fangyuan) was completed and opened to traffic at 12 noon on the 8th. It starts from the Fangyuan Interchange of Provincial Highway 61 in the west, connects Erlin and Puyan in the east, and connects to the existing Provincial Highway 76, connecting Provincial Highway 61, National Highway 1 and National Highway 3. The journey from Caotun to Fong Yuan is shortened from about 55 minutes to 35 minutes, saving about 20 minutes. Chief Executive Officer Zhuo Rongtai pointed out that this section directly connects Fangyuan Industrial Zone, Erlin Zhongke Base and Precision Park, improving the core capacity of the central precision smart park, and has disaster relief and medical referral functions. The project adopts a sponge road design, which combines flood detention and landscape green corridors, and integrates human-oriented environment and bicycle paths. The planning of this road section can be traced back to the "National Six-Year Economic Construction Plan" in 1991. In 2018, the extension project was approved by then Executive President Lai Ching-te and took about 20 years to complete.
