在后张法梁的施工过程中,预应力管道压浆是桥梁施工质量控制的关键要素之一。调查及实践表明,以往施工的一些桥梁由于施工、管理、监督等不到位,预应力管道漏压或根本不压浆,导致桥梁早期损坏或达不到设计寿命,此类情况甚至在一些国家重点特大桥工程中也屡见不鲜。因此,管道压浆问题应引起工程建设、施工及监理三方的高度重视,切实采取必要的管理和技术措施,确保压浆质量。 During the construction of post-tensioning beam, pre-stressed pipe grouting is one of the key elements of bridge construction quality control. The investigation and practice show that some bridges in the past are not in place due to construction, management and supervision, and the prestressed pipelines are under pressure or not grouted at all, resulting in early damage to the bridge or failing to reach the design life span. Even in some national priorities Bridge project is also uncommon. Therefore, the pipe grouting problems should be caused by the construction, construction and supervision of the three parties attach great importance to effectively take the necessary management and technical measures to ensure the quality of grouting.
