预制节段拼装结构套筒连接检测方法综述

A Review on Detection Method of Sleeve Connection of Prefabricated Segmental Assembly Structure

摘要:

随着我国逐步推进预制节段拼装结构的应用，灌浆套筒作为节段拼装可靠的钢筋连接方式，广泛应用于桥梁建造中。现介绍目前钢筋套筒连接使用中容易产生的缺陷及其影响。针对这些问题，介绍了几种主要检测方法，对其检测原理进行简要阐述，总结检测效果及其适用范围，并归纳现有规范中对于这些检测方法的要求。同时，对于套筒连接施工中的质量控制，以实际工程项目为例提出了一些监控措施。

Abstract:

With the gradual promotion of the application of prefabricated segmental assembly structures in China, as a reliable rebar connection of segmental assembly, the grouting sleeve is widely used in bridge construction. The defects easily caused in the current use of reinforced grout sleeve connection and its effects are introduced. In view of these problems, several main detection methods are introduced. The detection principles are briefly expounded. The detection effect and the application range are summarized. And the requirements for these detection methods in the existing specifications are concluded. Meanwhile, taking a practice project as an example, some monitoring measures are put forward for the quality control in the construction of sleeve connection.
