76 killed in Nigeria boat capsize_我的网站

一 |     Abuja, Oct 10 (UNI) At least 76 people were killed after a boat capsized in the southern state of Anambra at the weekend, Nigerian President Muhammadu Buhari confirmed.



In a statement on Sunday, Buhari acknowledged that rescue agencies had officially reported the death toll of the tragedy on Friday and expressed his grief.



A passenger boat carrying 85 people capsized in the Ogbaru area of Anambra State on Friday, following rising floods in that area, according to the statement.



An investigation had been launched to determine "other causes of the incident" besides floods, Thickman Tanimu, the southeast zonal coordinator of the National Emergency Management Agency (NEMA), was quotes as saying by local media.



Following the tragedy, Nigeria's National Inland Waterways Authority and the NEMA have embarked on rescue and recovery missions in Anambra.



Buhari said he has directed other rescue and relief agencies to rush to the site, urging the relevant government agencies to check the safety protocols on local transport ferries to make sure such incidents can be avoided in the future.

UNI/XINHUA PRT。    今天，中国铁路官方介绍了全国首位女盾构机司机，她就是“95后”萌妹子杨涔，操作盾构机驰骋在百米深的海底。

二 | 她参与建造的是我国最深的海底隧道——珠江口隧道，深江高铁（深圳至江门）的全线控制性工程。水下最大埋深达115米，最大水压1.06兆帕，长距离穿越几十种复杂地层，这种难度的施工在全世界也数罕见。两台量身定制的国产盾构机“深江1号”“深江2号”犹如巨型“穿山甲”凿岩破壁。杨涔操作的就是“深江2号”，总长133米、总重约3900吨。盾构机内部深长开阔，分布着众多精密线路，走入其中，仿佛置身一座机械城堡。

三 | 驾驶室约15平方米，这里拥有200多个按钮、9块屏幕，还有各类通话器，闪烁的指示灯让人目不暇接。整个操作台分为推进系统和环流系统。据了解，盾构机长距离掘进后必须精准实现对接，犹如在大海中穿针引线，对盾构机掘进过程中的动态控制要求极为苛刻。盾构机看起来巨大，却是缓缓前行，每分钟仅能推进几厘米。

四 | 目前服役的大多数盾构机日均掘进约5至10米，而“深江2号”创下日掘进24米、单月最高纪录342米的好成绩。
