3 children killed in New Orleans house fire allegedly set by their father: Police_我的网站

一 |     Three children were killed in a house fire in New Orleans early Wednesday morning that was allegedly set by their father following an apparent domestic dispute, police said.The father -- identified by police as Joseph Washington Sr., 29 -- was apprehended following a manhunt Wednesday and faces multiple charges including second-degree murder, according to New Orleans Deputy Superintendent Ryan Lubrano."We are here because of the tragic and senseless, horrific deaths of three young children last night in a domestic violence situation," New Orleans interim Police Chief Anne Kirkpatrick said at a press briefing Wednesday.The children's mother called 911 at 11:55 p.m. Tuesday night to report that their father intended to burn down their house, New Orleans police said. A fire was reported at the address "moments later," police said.The mother was not at the home when the fire started but was on her way there, according to police."He's going crazy," the mother said in a 911 call released by the Orleans Parish Communications District. "I'm at work. I'm trying to hurry up and go there right now."The mother told the 911 operator that her ex-husband was screaming and "said he's about to burn the house" while begging for police to hurry.First responders found the house engulfed in flames, police said. A 5-year-old girl and an 8-year-old boy were rescued from the home by firefighters, but were pronounced dead at a hospital about an hour later. The body of a 3-year-old boy was also recovered from the home and he was pronounced dead at the scene.Washington was identified as the prime suspect in the homicides, police said. His car was found earlier Wednesday in Gretna, partially submerged in the Mississippi River, police said. He was later apprehended on the I-610 after allegedly attempting to flee by jumping off the overpass and taken to a local hospital for treatment of injuries sustained in the fall, police said.Washington has been charged with three counts of second-degree murder, three counts of second-degree cruelty to a juvenile and one count of aggravated arson, police said. The charges could change, Lubrano said.The children's cause of death will be determined by the coroner.What sparked the fire is currently under investigation, Lubrano said. Police are also reviewing the parents' custody arrangement and whether officers have responded to the home before."Collectively we are outraged, we are disappointed, we are deeply saddened," interim Chief Kirkpatrick said while surrounded by members of the community during the briefing."The person responsible will be held accountable," she added.。          　　世界最大直径水下盾构隧道、国内首条穿黄单洞双层盾构隧道——济南黄岗路黄河隧道于8月25日上午正式通车。这条新动脉的贯通，将大幅加速人才、资源与产业在黄河两岸的流动，为济南跨河发展注入强劲动能。      　　济南黄岗路黄河隧道自2022年开工，历时四年建成。施工采用开挖直径达17.5米的“山河号”盾构机，刀盘面积达240平方米，堪称“巨无霸”。

二 | 济南黄河段为典型的“地上悬河”，河床高出南岸城区约5米，隧道需下穿黄河大堤及黄河敏感区，最深覆土达49.2米，最大水土压力达6.3巴，且长距离穿越粉质黏土层，最大硬度41兆帕。“盾构机直径每增加一分，制造难度与风险系数便呈几何级上升。”中铁十四局济南黄岗路黄河隧道项目现场负责人周祥坦言。      　　面对极端复杂的地质条件，项目团队依托丰富的穿黄经验，为“山河号”搭载了“五官一脑”智能化装备系统，构建掘进“智慧大脑”，实现全流程感知、预警与智能决策。

三 | 刀盘采用大开口率带压复合型设计，并配备伸缩式主驱动、开挖仓伸缩摄像头等先进装置。针对钙质结核、“黏糕状”地层等难题，团队研发应用金刚石刀具、碎石机及双管路液压采石装置，成功在黄河下实现全程3.3公里连续掘进不换刀，创下同类工况纪录。     　　针对特大断面管片上浮问题，采用第四代同步双液注浆技术与同步检测设备，确保施工安全，其间最高日进尺18米、月进尺426米，刷新了17米级盾构施工的世界纪录。      　　在绿色环保方面，这条隧道北岸紧邻济南一级水源地，泥浆处理必须“零污染、零外排”。项目自主首创“絮凝+提浓+压滤”工艺，使泥浆日处理效率提升50%，滤饼含水率降至30%以下，实现尾水循环利用与全量零外排，为邻近水源保护区的盾构工程提供了绿色范本。     　　济南黄岗路黄河隧道采用单洞双层布置，一次掘进实现双向通行，既集约利用地下空间，又较传统方案节省约15%投资;内部4.2米净高可满足公交、消防及救援车辆通行，极大提升通行效能，为城市跨江越河通道建设提供了新的结构范式。

四 |      　　施工期间，项目累计攻克开挖面稳定、悬河大堤沉降控制、特大断面上浮、泥浆绿色处理等28项技术难题，发表科技论文30余篇，申报发明专利及实用新型专利22件，形成17米级盾构施工成套技术体系，有力提升了我国特大直径盾构建造能力。      　　以国家最高科学技术奖获得者钱七虎院士为组长的专家组评价称，该隧道在智能化、机械化、绿色化施工方面的实践，将推动我国盾构隧道技术迈出一大步，其建成对我国水下交通隧道建设具有里程碑意义。
