预制节段拼装结构套筒连接检测方法综述

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。本文介绍了目前钢筋套筒连接使用中的容易产生的缺陷及其影响,针对这些问题,本文介绍了几种主要检测方法,对其检测原理进行了简要阐述,总结了检测效果及其适用范围,并归纳了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,本文以实际工程项目为例提出了一些监控措施。

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

SWith the gradual promotion of the application of prefabricated assembly structures in China, grouting sleeve, as a reliable connection for prefabricate members, is widely used in bridge construction. This paper introduces the defects and their effects in the use of grout sleeve connection. In view of these problems, this paper introduces several main detection methods, briefly expounds their detection principle and range of application, and summarizes the requirements for these detection methods in the existing specifications. Meanwhile, this paper takes some projects as an example and puts forward some monitoring measures to control the quality of grout sleeve connection.
