节能之路 生态之路 科技之路

2017-08-29 09:23:11   中国青年网

实施创新驱动 建一条科技绿色之路

打造新型绿色服务区。2016年8月投入使用的伶俐服务区采用了高速公路、服务区外场、停车场三级车位显示引导系统、地源热泵空调、污水处理中水回用系统等,均属我区率先采用的技术,其中仅地源热泵空调一项,与传统空调系统相比,预计每年就可节约用电40%,充分展现了绿色低碳技术的应用成效。

推进信息技术应用。加快发展智慧交通,通过建设公众出行服务信息系统、电子不停车收费系统、绿色通道车辆多特征融合检测系统、超限超载不停车预检系统等,有效提高公路网出行信息服务水平、出行者的出行安全性及高速公路的服务水平,减少交通拥堵,提高运输效率。项目建成后将在我区率先实现全程电子监控路面车辆运行状况,确保路况信息及时发布和快速处理。该项目拟投资5120万元在收费站开通ETC车道26条,在新兴和伶俐等收费站安装2套绿色通道融合检测系统和超限超载不停车预检系统,在沿线设置情报板发布系统及设备70套。信息化程度提升,确保运营通畅,减少事故率,每年节油170万升,节能量折合标煤2507吨,年减少CO2排放5433吨。

使用泡沫轻质土。项目对于纵坡抬高较大的路段,设计采用新型材料泡沫轻质土进行填筑,该材料可垂直填筑,进行浇筑式施工,不新增占地,施工便捷,最大程度地节约土地资源,促进资源的循环利用,更节能环保,更合理经济。

使用无砂大孔混凝土。无砂大孔混凝土是一种新型半刚性基层材料,对改善公路地下水破坏状况、延长路面使用年限有着重要作用。该项目预计在路面拼接、桥涵台背路基处理中共应用无砂大孔混凝土约 30万方。

积极推广“四新”技术。2017年该项目上报“四新”技术9项,其中“无砂大孔砼同步滑模摊铺工艺”“振动拌和与高性能长寿命沥青路面技术”“3D摊铺自动控制系统”“水下系梁无封底钢吊箱施工技术”等4项重大“四新”技术的实施,获上级单位好评和认可。截至目前,该项目已在国内核心刊物上发表了5篇科技论文,获得专利1项。

展望未来,广西绿色公路发展任重道远,交通运输部、自治区交通运输厅及广西交通投资集团希望通过柳南高速改扩建项目的建设营运,打造绿色低碳循环公路建养模式、探索绿色循环低碳交通发展路径,为推动全区交通运输节能环保“十三五”发展规划奠定坚实的基础。
