近期在滨海公路南段一期工程施工的现场,有一项施工技术颇有趣味——施工单位为了保证跨海大桥桥桩的坚固,创新性地在混凝土中添加了绵白糖。正在施工的陈家贡跨海特大桥是滨海公路南段一期工程建设难度最大的一段。大桥经过的海域海水氯离子含量高、腐蚀性强,一般的混凝土都无法使用。为解决这个难题,建设单位邀请了北京大学和清华大学的专家对症下药,研制出了高耐久性海砼混凝土,为顺利打下跨海大桥的桥桩奠定了基础。为
Recently, on the scene of the first phase of the construction of the southern section of Coastal Highway, one construction technique is quite interesting. In order to ensure the strong and innovative bridge pile of the bridge, the construction unit creatively added soft white sugar to the concrete. Under construction, the Chenjiagong Transoceanic Bridge is the most difficult section of the first phase of the construction of the southern section of the coastal highway. After the bridge through the sea water, high chloride ion content, corrosive, the general can not use concrete. To solve this problem, the construction unit invited experts from Peking University and Tsinghua University to prescribe the right remedy and developed the high-durability marine concrete, laying the foundation for the smooth laying of bridge piles on the sea-crossing bridge. for
