狮子洋通道是继港珠澳大桥、深中通道之后大湾区又一超大型跨江通道工程,全长约35公里,连接广州市南沙区和东莞市虎门、沙田两镇,主体工程由跨江主桥狮子洋大桥和两岸陆域引线工程组成,建成后将推动粤港澳大湾区城市群一体化融合发展。
作为全线控制性工程,狮子洋大桥是主跨2180米的双层钢桁悬索桥,创下双层悬索桥“主跨跨径、车道数量、主塔塔高、锚碇基础、主缆直径”五项世界第一。
猫道是狮子洋大桥主缆架设等上部结构施工的高空临时作业平台,被称为超级工程的“空中生命线”,分上游、下游两幅。
针对狮子洋大桥2180米超大跨径、珠江口海域台风多发、高空风场复杂等世界级施工难题,项目团队开展了大量专项科研攻关,建成了单幅宽度达6.26米的世界级猫道,比常规大跨悬索桥猫道宽度提升约50%,可满足重达4.3万吨、直径约1.5米的超大主缆多工序并行作业需求,拓展高空施工作业面,提升多班组同步施工能力与作业安全性。
保利长大狮子洋通道T9标项目总工匡一成介绍,单幅猫道承重索采用16根直径60毫米、强度2160兆帕的高强钢丝绳,形成稳定可靠的承载系统;为应对超310吨的最大受力,承重索预埋件完成了专项锚固力荷载试验;整套猫道体系通过专业风洞试验,可适配珠江口复杂多变的海域风场,从源头夯实了结构安全根基。
“项目在行业内首次运用爬绳机器人开展绳索测量作业,可减少人工高空测量风险,操作人员通过遥控器驱动机器人即可采集坐标数据和承重索精度高程,并以此进行调索工作,可减少人工测量风险,实现高空测量作业精准化及智能化,确保16根承重索均匀受力。”匡一成介绍。
项目同步搭建起“结构受力监测+设备工况监控+气象超前预警”三位一体的全维度智能监测体系。在锚固关键点位布设高精度压力环传感器,24小时不间断采集锚固力数据;联动东西锚碇、主塔卷扬机智能系统,实时管控牵引拉力、作业速度;定制专业气象平台,精准捕捉标段内的风速、降雨变化,提前预警极端天气,推动猫道施工由传统经验模式转向数字化、精细化、科学化管控,为300余米高空施工安上了“智慧天眼”。
目前,项目团队将同步开展面网铺设、护栏绳安装、横向通道架设等猫道施工,计划今年底前完成猫道架设,保障主缆架设关键工序高效开展,高质量推进这座世界级超级工程建设。(完)

A drowning accident occurred on the 9th at the sand dam below the Laiyi Bridge in Laiyi Township, Pingtung County. A 13-year-old junior high school student was caught in the rapid water while playing in the water. The police and the Water Resources Department urgently mobilized and deployed excavators to intercept the flow and lower the water level. The boy was successfully found at Jishuikou, Erfeng Town. He became conscious after being sent to the hospital.

A fire broke out in the kitchen on the second floor of a 14-story community building in Section 2, Xingnan Road, Zhonghe District, New Taipei City last night. The fire department sent 38 vehicles and 87 personnel to the scene to put out the fire. They successfully rescued the trapped father and daughter and sent them to the hospital for preventive examination. The fire did not spread to other floors. The cause of the fire is yet to be investigated.

The first prize of No. 115000243 Jincai 539 drawn on October 7 was 1 bet, which was drawn from the "Baohewang Betting Station" in Section 5, Zhongxiao East Road, Xinyi District, Taipei City. Each bet can win 8 million yuan.

A fire broke out in a house on Minsheng Road, Chenggong Town, Taitung County in the evening. An explosion was heard at the scene, affecting the houses behind. The fire brigade was successfully dispatched and the Donghe detachment was dispatched. The fire was controlled within 30 minutes. It was initially determined that the fire point was a multi-span iron warehouse where a large amount of wood and sundries were stored. There were no casualties in the entire incident.

At 5:44 a.m. on the 7th, a tour bus lost control and crashed into a house in Beipu Township, Hsinchu County. Three of the 22 passengers on the bus were injured. One of them was unconscious and sent to the hospital for emergency treatment. The police have cordoned off the scene to investigate possible causes such as fatigue driving or mechanical failure.

The first phase of the Tainan urban railway undergrounding will be switched after the last train leaves at 10:29 pm on October 16. The first underground train will leave for Hualien at 6:29 am on the 17th. The century-old pavement platform of Tainan Station will become history, and highway passenger connection services will be provided during the construction period.
