   9月13日凌晨1点38分，随(sui)着(zhe)爆(bao)破声响起，西安(an)市引蓝济(ji)李引水工(gong)(gong)程(cheng)(cheng)引水隧洞实(shi)现全(quan)线安(an)全(quan)顺利精准贯(guan)通，标志着(zhe)工(gong)(gong)程(cheng)(cheng)建设取得阶段性(xing)的成果，为项目早日全(quan)面竣(jun)工(gong)(gong)、实(shi)现通水奠定了良(liang)好基础。

   “2015年(nian)(nian)白鹿原水(shui)(shui)(shui)厂供水(shui)(shui)(shui)以来，由于水(shui)(shui)(shui)库(ku)上游水(shui)(shui)(shui)量偏少(shao)，远低(di)于设计年(nian)(nian)径流(liu)量，严重制约了城市(shi)(shi)的(de)供水(shui)(shui)(shui)量。经市(shi)(shi)委、市(shi)(shi)政(zheng)府研究，决定实施(shi)引(yin)蓝济李(li)(li)(li)引(yin)水(shui)(shui)(shui)工(gong)(gong)(gong)程(cheng)。”李(li)(li)(li)家河(he)水(shui)(shui)(shui)库(ku)管(guan)(guan)理(li)公(gong)司引(yin)蓝济李(li)(li)(li)引(yin)水(shui)(shui)(shui)工(gong)(gong)(gong)程(cheng)建(jian)管(guan)(guan)处主(zhu)任(ren)董亚军说。作为(wei)市(shi)(shi)级重点民生项目，2021年(nian)(nian)7月开(kai)工(gong)(gong)(gong)的(de)引(yin)蓝济李(li)(li)(li)引(yin)水(shui)(shui)(shui)工(gong)(gong)(gong)程(cheng)，由引(yin)水(shui)(shui)(shui)渠(qu)首和引(yin)水(shui)(shui)(shui)隧洞组成。通(tong)过(guo)新(xin)建(jian)低(di)坝(ba)枢纽、输(shu)水(shui)(shui)(shui)隧洞，将(jiang)蓝田蓝桥(qiao)河(he)水(shui)(shui)(shui)自流(liu)引(yin)至李(li)(li)(li)家河(he)水(shui)(shui)(shui)库(ku)上游的(de)东采峪支流(liu)黄沙沟中，通(tong)过(guo)有效补充李(li)(li)(li)家河(he)水(shui)(shui)(shui)库(ku)水(shui)(shui)(shui)量，可提升对纺(fang)织城、曲江(jiang)新(xin)区等区域的(de)供水(shui)(shui)(shui)保障。

   引(yin)蓝(lan)济李(li)工程是(shi)(shi)西安(an)市(shi)(shi)“河湖(hu)连通引(yin)水(shui)(shui)”的(de)重要建(jian)设(she)内容，也是(shi)(shi)践行(xing)共(gong)享发展理(li)念、完善城市(shi)(shi)基(ji)础设(she)施、保障城市(shi)(shi)供水(shui)(shui)安(an)全、缓解城市(shi)(shi)供水(shui)(shui)紧张的(de)重大举措(cuo)。“在西安(an)水务集团的领导和(he)(he)支持下，开工(gong)以(yi)来，我(wo)们聚焦(jiao)项目建设，紧(jin)盯(ding)进(jin)度(du)(du)和(he)(he)目标(biao)(biao)(biao)(biao)(biao)(biao)、严查风险和(he)(he)隐患，努力克(ke)服外围环境差、施工(gong)难(nan)度(du)(du)大等(deng)种种困难(nan)，历(li)经700多个夜(ye)以(yi)继日(ri)的艰苦努力，提前47天完成隧(sui)洞(dong)(dong)(dong)开挖任务。”董亚军说。今(jin)年6月30日(ri)，引(yin)(yin)(yin)(yin)蓝济李(li)引(yin)(yin)(yin)(yin)水工(gong)程(cheng)施工(gong)四(si)标(biao)(biao)(biao)(biao)(biao)(biao)段已顺利完成施工(gong)任务。8月30日(ri)，引(yin)(yin)(yin)(yin)蓝济李(li)引(yin)(yin)(yin)(yin)水工(gong)程(cheng)施工(gong)二标(biao)(biao)(biao)(biao)(biao)(biao)段和(he)(he)施工(gong)三(san)标(biao)(biao)(biao)(biao)(biao)(biao)引(yin)(yin)(yin)(yin)水隧(sui)洞(dong)(dong)(dong)上游段顺利“会师”。随着引(yin)(yin)(yin)(yin)水隧(sui)洞(dong)(dong)(dong)施工(gong)三(san)标(biao)(biao)(biao)(biao)(biao)(biao)段和(he)(he)施工(gong)四(si)标(biao)(biao)(biao)(biao)(biao)(biao)段下游段贯(guan)通，标(biao)(biao)(biao)(biao)(biao)(biao)志着工(gong)程(cheng)整(zheng)个隧(sui)洞(dong)(dong)(dong)实现全线精准贯(guan)通。

   “引蓝济李工(gong)(gong)(gong)程(cheng)隧(sui)(sui)洞(dong)总长9037米(mi)(mi)，其中引水(shui)隧(sui)(sui)洞(dong)7227米(mi)(mi)、施(shi)(shi)(shi)工(gong)(gong)(gong)支(zhi)洞(dong)1810米(mi)(mi)，隧(sui)(sui)洞(dong)贯穿崇山峻岭(ling)，埋(mai)深长，地(di)(di)层(ceng)岩性复杂。”董亚军说，在隧(sui)(sui)洞(dong)施(shi)(shi)(shi)工(gong)(gong)(gong)过程(cheng)中，各项目建设单位严格落实安全生(sheng)产(chan)责(ze)任(ren)制，遵守“先通风、再检测、后作业”的(de)原则，严控施(shi)(shi)(shi)工(gong)(gong)(gong)质(zhi)量(liang)和安全管理(li)。面对复杂的(de)地(di)(di)质(zhi)情况和恶(e)劣的(de)施(shi)(shi)(shi)工(gong)(gong)(gong)环境(jing)，各标段遵循“短进尺、弱爆破(po)、强支(zhi)护(hu)、快封闭(bi)、勤(qin)测量(liang)”的(de)施(shi)(shi)(shi)工(gong)(gong)(gong)原则，根(gen)据围岩变化(hua)及时调整优化(hua)施(shi)(shi)(shi)工(gong)(gong)(gong)方案，降低施(shi)(shi)(shi)工(gong)(gong)(gong)风险，有效保障(zhang)了引蓝济李引水(shui)工(gong)(gong)(gong)程(cheng)引水(shui)隧(sui)(sui)洞(dong)顺(shun)利平稳掘进。

   “隧(sui)洞(dong)贯通后，我(wo)们将(jiang)立(li)即进行(xing)洞(dong)内二次衬(chen)砌施工，计划年底前完(wan)成施工任务，实现通水。”董亚(ya)军说。
