随着我国高速公路的发展,新建高速路越来越多,那么道路交叉不可避免,设计上采用的形式有分离立交和互通立交形式。无论采用什么形式新建高速公路施工对被交叉高速公路都有较大影响,因此道路产权单位极其关心新建道路采用的技术方法对权属道路有无质量影响,施工过程和交工验收后对车辆运营安全是否构成威胁?按照我国《中华人民共和国公路法》及其《公路安全保护条例》要求对新建公路单位所采用的施工技术进行技术和安全评价。下面我们以蓟汕高速公路施工跨越京津高速公路为例对新建公路跨越高速施工技术进行研究。
With the development of the expressway in our country, more and more expressways are newly built, the intersection of roads is inevitable. The forms adopted in the design are the forms of separated interchange and interchange. No matter what form of new expressway construction has a greater impact on the cross-freeway, so the road property unit is extremely concerned about the new road with the use of technical methods have no right to ownership of the road quality, construction process and delivery inspection of vehicle operation safety Is it a threat? According to China’s “Highway Law of the People’s Republic of China” and its “Regulations for the Protection of Road Safety,” technical and safety evaluation of the construction technology used in the construction of new highway units. Here we take the Jishan-Shantou Expressway construction across the Beijing-Tianjin Expressway as an example to study the construction of new high-speed road construction technology.
