城市桥梁混凝土桥面防水粘结层的施工管理

Construction Management of Waterproof Bonding Layer of Urban Bridge Deck

为延长城市桥梁的使用寿命,提高混凝土桥面的耐久性,在某桥梁环氧沥青防水粘结层的施工中监理单位参与方案选择、施工组织审查、原材料检测,旁站该材料的全过程施工,并组织了第三方平行施工检测,结果表明粘结强度和剪切强度远远高于规范要求,各项性能指标优越,达到并超过了设计要求。

In order to prolong the service life of urban bridge and improve the durability of concrete deck,the supervision unit takes part in selection of scheme,checkup of construction organizational,detection of raw materials and whole construction of process of materials in the construction of a bridge epoxy asphalt waterproof bonding layer,and organizes the parallel construction detection of a third-party.The results show that the bond strength and shear strength are much higher than the regulatory requirements,and various performance indexes are superior,which achieve and exceed the design requirements.
