标题: 绵阳双碑大桥桥梁主体已完工
“大桥桥梁主体结构建设已完工，目前正在加紧推进桥面附属工程、滨河北路下穿通道和泵站建设。”30日，记者在位于高新区金域丽江小区外的双碑大桥建设现场采访时，绵投集团嘉来建工现场负责人向记者介绍。


　　双碑大桥北起双碑东街，斜跨安昌河，南接飞云中街，路线全长约1公里，其中主桥长约614米，最大跨径为152米，道路等级为城市次干道，双向四车道。作为链接城南和城西的又一条城市重要通道，双碑大桥的建设对我市“建设新区、完善组团、提升旧城”战略起到交通辅助支撑作用。30日上午10时许，记者在双碑大桥建设现场，只见大桥雏形已显，工人们正在桥面上忙着对人行道实施防裂网作业。

　　滨河北路下穿通道作为双碑大桥工程建设的关键组成部分，只有下穿通道完成后，双碑大桥北岸引桥才能施工。在下穿通道施工现场，只见这里的建设场面热火朝天，机械声轰鸣。工人们正忙着配合泵车等机械，浇筑西段B船槽底板的垫层，不远处的挖掘机等机械正在实施下穿通道基坑开挖作业。该下穿通道最深要挖8米，为确保安全，项目严格按照规范要求进行。在开挖前首先对下穿通道两侧密织了172根钢筋混凝土的支护桩，为开挖基坑打下坚实基础。这几日在开挖作业中，他们还边挖边对下穿通道侧壁进行喷锚，以保障绝对安全。双碑大桥滨河北路下穿通道为双向四车道，建成后只通行机动车，整个下穿通道长度为335米。

　　双碑大桥下穿通道的建设充分考虑排水问题，在通道内建有收集积水井及一体化泵站。目前，一体化泵站土建已完成85%，力争6月初完工。

　　双碑大桥建成后，将减轻飞云大桥（飞来石大桥）交通压力，减少高新区至城南穿越性交通对火车站片区及核心区的影响。
