日前，长江口深水航道工程迎来开工以来最严峻“大考”，刚经受“苏拉”、“达维”双台风考验，台风“海葵”又来袭。相比前几天的双台风，“海葵”来势更为凶猛。

a，Yangtze river estuary deep channel in the most serious since the project started“Big test”，Just suffered“sura”、“davey”Double typhoon test，The typhoon“Sea anemone”And incoming。A few days before the typhoon than double，“Sea anemone”Comes more fierce。

　　三台风在如此短时间内密集夹击长江口，这在长江口深水航道治理工程1998年开工以来实属少见。面对“大考”，长江口航道管理局在思想保障、物质保障和组织保证上做好了准备工作。

Three typhoon in such a short time intensive flanked the Yangtze estuary，This in the Yangtze estuary deepwater channel regulation project started really rare since 1998。face“Big test”，The Yangtze estuary waterway administration thought in security、Material guarantee and organization guarantee ready to work on。

　　今年是长江口12.5米深水航道竣工验收后正式投产一周年，根据长江口深水航道治理一、二期工程竣工后屡现疏浚困难的特点，长江口航道管理局年初就未雨绸缪，在编制2012年航道维护应急预案时充分考虑特殊情况下的应急保障措施。

This year is 12.5 meters of the Yangtze estuary deepwater channel after the completion acceptance formally put into production in a week，According to one of the Yangtze estuary deepwater channel、After the completion of the second phase of the project is the characteristics of dredging repeatedly difficulties，The Yangtze estuary waterway administration in early for a rainy day，In 2012 years of channel maintenance when the emergency response plan full consideration of special situations of emergency security measures。

　　考虑到7至9月是上海地区多台风的季节，该局合理使用贮泥坑抛泥，先行预留距离施工区段较近的贮泥坑为贮泥坑窖，为台风后尽快清除浮淤泥提供保障。据测算，仅此项优化措施，就相当于增加了一条一万立方米挖泥船一个月的施工力量，大大提高了清淤施工效率。

Considering the July to September in Shanghai is more than the typhoon season，The reasonable use the mud into the mud，First reserve construction section of close distance the mud pit mud for storage，For as soon as possible after the typhoon clear float silt provided protection。According to estimates，That item optimization measures，Is equivalent to increase a ten thousand cubic meters mire ship a month of construction strength，Greatly improving the "s" shape the construction efficiency。

　　在长江口深水航道维护工程招标时，该局还结合台风季节航道各区段的回淤特点和国内疏浚市场现状，引进时效高、舱容大、性能优的挖泥船进场。

In the Yangtze river estuary deep channel maintenance engineering bidding，The bureau also link to the typhoon season channel of each section back silting characteristics and domestic dredging the market situation，Introduce aging high、Cabin let big、Performance of the optimal mire ship comes into play。

　　“苏拉”、“达维”双台风来临前，长江口航道管理局及时启动应急预案，组织对参与长江口深水航道维护工程的所有施工、监理单位进行防抗台风督促检查。

“sura”、“davey”Double before the typhoon，The Yangtze estuary waterway administration launched the emergency response plan in time，The organization to participate in the Yangtze river estuary deep channel maintenance engineering all construction、Supervision company to the supervision and inspection of the typhoon。

　　在台风靠近我国48小时警戒线时，该局应急办公室即安排专人进行台风预报信息跟踪，每天组织人员会商应对台风举措。台风临近，绞吸式挖泥船全部撤离施工区域进黄浦江避风，在深水航道外口段施工的三艘耙吸式挖泥船选择横沙锚地抛锚避风，其他施工船舶也及时避风。该局派出“航巡01”巡逻船，巡查防台风措施落实情况。双台风过后，挖泥船随即开赴施工现场，测量船及时组织测量。

Typhoon in China in near 48 hours when the cordon，The emergency office that will arrange for the typhoon forecast information tracking，Every organization staff in consultation with the typhoon measures to deal with。The typhoon is near，Heave suction hoper dredger complete evacuation construction areas into hiding the huangpu river，In the deep water channel for the construction of the three mouth the ship suction hoper dredger choose broke down the sand anchorage shelter，Other construction in time from the ship。The bureau sent“Air tour 01”Patrol ship，Search typhoon measures to carry out the situation。Double after a typhoon，Heading into the mire ship immediately construction site，Also in time measurement organization。

　　记者了解到，为了最大限度降低台风对通航的影响，长江口航道管理局在迎抗台风的同时，提前部署抢通清淤工作。该局正多方联系，组织社会力量，寻租大型挖泥船，台风“海葵”过后，船舶将迅速驶入现场开展挖泥。此外，该局还将召开“确保长江口12.5米深水航道立功竞赛推进大会”，组织挖泥船间的对口竞赛，全力维护航道水深，确保长江口深水航道畅通。

The reporter understands，In order to minimize the influence of typhoon on navigation，The Yangtze estuary waterway administration meet resistance at the same time in the typhoon，The "s" shape the deployment in advance。The bureau is various contact，Organization social forces，Rent-seeking large mire ship，The typhoon“Sea anemone”after，Ships will rapidly develop into the dredging。In addition，The council will hold a“Ensure that the Yangtze estuary deepwater channel 12.5 meters of congress ultimately competition”，Organization of the right competition between mire ship，To maintain channel depth，Ensure Yangtze river estuary deep channel is clear。
