  中新Welcome back. It's good to see you. Click below to log in to the rewards program at your property.网武汉12月4日电 (Welcome back. It's good to see you. Click below to log in to the rewards program at your property.王梦媛)据长江航道局4日消息,长江上游泸州小米滩水道航道养护疏浚任务已提前完成,有效保证了枯水期2.9米水深航道维护标准,从而保障了该水域航道的畅通。

  据介绍,小米滩水道位于长江上游航道里程905.0—907.0公里处,该区域河道蜿蜒狭窄,水流湍急,整个滩段航槽呈“S”形,常年流速约为3米每秒,是长江上游著名的浅险滩之一。由于今年汛期流量较大,退水过程迅速,导致汛期沉积的大量泥沙在航槽内未能得到充分冲刷,航道条件恶化,给上下行船舶的通行带来了困难。因此,及时对该浅区进行疏浚,确保航道畅通变得尤为重要。按照原定计划,小米滩水道的航道养护疏浚任务预计需要41天才能完成。

  为确保疏浚任务的顺利进行,长江航道局采取禁航与非禁航相结合的施工策略,以减少施工对过往船舶特别是下行船舶转向的影响;制定了针对性的疏浚方案,加强了施工现场的管理,并进行了大比例的精准测量,从而提高了疏浚挖泥的效率,并确保了现场的安全;同时,制定了每日工作进度图,保证了日均工作时长;专业挖手严格控制挖掘质量和深度,从而提升了船舶施工的工效。最终,仅用29天时间便提前完成了本次养护疏浚任务,比原计划提前了12天。

  据悉,2024年枯水期,长江航道局将对干线航道上游合江门至丰都段共计7个水道进行养护疏浚施工,主要包括对叉鱼碛水道、纳溪水道、三角碛水道、香炉滩水道、小米滩水道、鱼洞水道实施养护疏浚以及对东溪口水道实施清障施工,其中小米滩水道是该段航道维护疏浚的核心节点。(完)
