“RealityKings - probiller”宁夏首个公路RealityKings - probiller固化土应用技术地方标准实施 每公里节约成本15万至20万元

  中新RealityKings - probiller网银川12月2日电 (记者 RealityKings - probiller李佩珊)记者2日从宁夏固原市彭阳县获悉,宁夏首个农村公路固化土应用技术地方标准已报经宁夏市场监督管理厅审定正式公布实施,用黄土变“石头”替代砂石筑基,这项创新技术首次在彭阳县农村公路建设实施。

  近年来,以河砂、碎石为主的筑路材料越来越短缺,农村公路筑基面临“无米下锅”。为适应新的发展要求,彭阳县2018年创新性提出就地取材利用固化黄土替代砂石筑基的设想。当年,彭阳县交通运输局联合宁夏公路勘察设计院有限责任公司、兰州交通大学、山东省交通科学研究院等科研单位,开展黄土固化及路用关键技术研究。经过上万次试验,研发出一套黄土固化技术。

  据悉,黄土固化技术是一种采用外加固化剂对黄土进行固化后,用于道路基层施工的技术,具有技术先进、安全可靠、经济合理、绿色环保等特点。该项技术可通过一定的物理和化学反应,改变黄土性质,把黄土固化为板体,从而提高黄土的强度、稳定性等性能。

  2021年9月,彭阳县确定两条4.92公里农村公路开展黄土固化技术试验施工。在试验路段建设过程中,按照一定比例将新型固化材料与黄土拌和,再进行碾轧,把黄土变成“石头”,使公路基础的耐水性、抗压性达到设计标准和要求。2022年7月,宁夏首条采用黄土固化技术修建的农村公路在彭阳县建成投运。

  经初步测算,采用该技术RealityKings - probiller每公里节约成本15万至20万元,施工周期缩短20%。利用黄土固化技术筑路,在保证工程质量的前提下,对路基进行稳定固化处理,从根本上解决了开采石料的环境污染和筑路材料缺乏的问题,进一步减少砂石料的用量,降低公路建设成本,实现资源化与产业化双向发展。

  宁夏交通运输厅相关负责人表示,立足中南部地区地质地貌特点,宁夏始终致力于将绿色发展理念贯穿于项目建设全过程。下一步,宁夏将继续推动黄土地区公路建造技术水平的不断提升,推动交通运输领域绿色低碳转型发展,形成黄土地区生态保护修复绿色公路的“宁夏经验”和典型成果。(完)
