北京80条核心区道路电力架空线年底将全部入地

2018-07-08 16:11:00    央广网

央广网北京7月8日消息(记者刘天思)7月7日凌晨1点,在北京市西城区南礼士路架空线入地工程现场,国网北京市电力公司工作人员正在进行设备吊装操作。当晚,南礼士路、黄寺大街、幸福大街、南横西街、白广路等18个施工现场同时火热作业中。目前,2018年首都核心区电力架空线入地工程第一阶段23项工程基本完成送电投产,第二阶段57项工程即将全面启动。

自2018年3月底以来,国网北京电力启动对东城、西城范围内80条道路两侧的电力架空线路进行入地改造,工作量达到2017年的1.7倍。工程提前4个月进场开工,目前第二阶段57项工程前期手续办理接近尾声,即将全面启动架空线入地工程“大会战”,将于供暖季前全面完工。

在2018年首都核心区架空线路入地改造工作中,国网北京电力充分考虑道路交通因素、关注百姓生活需求,从环保施工、降低扰民、保障出行、安全管控等方面入手,创新使用永磁起重器吊装钢板、配备高压雾炮进行湿法作业等新工艺、新理念,有效推进工程有序实施。

记者在首都核心区架空线入地施工现场看到,为了不扰民,施工人员采用永磁起重器吊装技术起吊道路施工用钢板。永磁起重器具有体积小,重量轻,吸持力强,安全系数高等特点,同时解决了传统方式下钢板吊装和铺设过程中噪音大、就位困难等问题。现场还使用静音发电机,发电机满负荷工作时最高声音在50分贝以下,环保静音。

在防尘降噪方面,今年全部土建施工采用湿法作业,每个土方作业点位配备高压雾炮,洒水车每间隔90分钟对路面进行一次洒水喷雾降尘,渣土运输采用环保密闭式渣土车辆进行清运,有效降低施工现场可吸入颗粒物浓度。
