“CSGO暴躁少女的玩家群体分析”湖北十堰版CSGO暴躁少女的玩家群体分析“南水北调”加快推进 改善中心城区用水

  中新CSGO暴躁少女的玩家群体分析网武汉11月15日电 (何易培CSGO暴躁少女的玩家群体分析 曾奇奇 黄伟锋)湖北省十堰市是南水北调中线工程核心水源区,也是湖北水资源低值区和水资源敏感地区。为改善中心城区用水条件和水生态环境,被称为十堰版“南水北调”的十堰中心城区水资源配置工程目前正加快建设。

  该工程为湖北省重点工程,以潘口水库为水源,通过新建潘口水库至马家河水库的引水线路,向中心城区供水。同时,通过新建马家河水库至百二河水库引水支线,向城区补充生态用水。引水线路总长73.139千米,采用全程无压自流输水方式,多年平均引水量1.66亿立方米。

  中交二航局十堰水资源配置工程项目负责人15日介绍,该局承建的第2标段是整个项目线路最长、支洞最多、难度最大的标段,具有“长、散、小、陡、险”等特点。工程以地下隧洞为主,总长23.58千米,其中新建4号隧洞是全线最长钻爆隧洞,单洞长约19.3千米;标段线路穿越7个村庄,设有7个施工作业区,点多面广,且都位于山岭地区,分布散;隧洞成型净断面宽3米、高3.5米,空间极其狭小,布置管线等辅助施工设施后,设备操作空间更小;近20公里长的主隧洞进出口高差仅4.7米,近似平洞,而施工支洞洞口高程均高于主洞高程,最大高差为85米,施工期洞内涌水,抽排水困难;隧洞穿越多条断层破碎带,施工过程中多次发生塌方、涌水等险情,安全风险极高。

  为顺利推进工程建设,项目团队根据不良地质条件,制定施工方案;采用超前地质预报技术,动态掌握洞内岩层变化趋势;创新研发出小断面引水隧洞超前掏心爆破开挖施工技术;严格遵循“短进尺、弱爆破、强支护、紧封闭、勤量测”的原则,加密变形监测点布置,及时开展综合性的超前地质预报,保障作业安全、质量和进度。

  鉴于工程地处南水北调核心水源区,为保障“一库清水永续北上”,项目团队坚持绿色施工。施工过程中产生的土石渣料、废水、废气、废油等进行全面控制,并采取临时拦挡、临时苫盖措施,以及修筑坡面格构、喷播植草等手段,及时对裸露土地进行复绿,做好水土流失防治工作。

  据悉,十堰市中心城区水资源配置工程建成后,将进一步优化该市水资源配CSGO暴躁少女的玩家群体分析置,完善城市功能、提升城市品质。(完)
