节能之路 生态之路 科技之路

柳南高速公路改扩建工程是自治区重点建设项目,也是交通运输部确定的绿色公路主题性示范项目、广西首个国家级“绿色公路”主题性示范项目,于2016年2月26日全线开工,计划2018年建成。该项目在规划设计、建设与施工、运营与养护中,统筹资源利用,加强生态保护,推广低碳技术,建设名副其实的节能绿色公路、生态绿色公路、科技绿色公路,力争打造成为广西乃至全国的绿色公路典范。

统筹资源利用 建一条节能绿色之路

充分发挥原有通道资源作用,有效降低资源能耗。项目改扩建总里程248.7 公里,其中新建道路里程40公里,其余208.7公里均采用拼宽或单侧拼宽方式实现对原道路利用。新建道路完工通车后,原旧高速公路以及沿线设施仍可作为城市道路实现再利用。利用率98.5%以上。充分利用原有高速公路建成八车道,与建设两条四车道高速公路相比,实现了节约土地资源20%以上。

线形组合优化设计的路段达6处,大幅度降低资源消耗率。原有高速公路建设时,局部路段按困难地形及经济性原则进行线形组合设计,最大纵坡达到4.8%,通行能力与服务水平均不能满足社会发展的需要。项目改扩建后按最大纵坡 3%对老路进行改造,运营初期日均货车通行 1.5万辆,按照每辆货车平均节约0.08升柴油计算,全年可节约44.3万升柴油。

实行耕作土剥离再利用,有效保护土地资源。项目是国土资源部明确的耕作层土壤剥离再利用的示范项目,广西交通投资集团新增投资约7200万元用于耕作层土壤剥离再利用工作,目前已完成耕作层土壤剥离112.8万立方米,实现再利用社会综合经济效益近3000万元。

推进废旧材料再利用,实现资源高效利用。项目在施工中对旧水泥混凝土、施工废粉等固体废弃物进行集料化再生重新利用,减少开山采石,节约资源,降低能源消耗,起到了良好的节能减排效果。同时,实现高速公路钢护栏再利用,对大量旧波形梁钢护栏进行改造处理,预计全线实施钢护栏再利用后可直接节约钢材7500 吨,节约建设成本4000 多万元,节约6000吨标准煤。

加强生态保护 建一条生态绿色之路

实施沿线绿化及生态防护。项目对互通匝道、边坡坡顶的占地界内、服务区外缘空间等公路占地内的原有植被尽可能地加以保护和利用,研究边坡草种混播的配置及比例,并选取碳汇能力强的植物物种,充分发挥植被的碳汇作用,建成后可有效消减噪声、保持水土和美化环境,同时形成年11.45万吨CO2吸收能力。
