T梁负弯矩压浆不密实的处理方法

Abstract In modern construction of T beam the key working procedure is tensioned prestress of the positive and negative bendingmoment and tunnel grouting. Due to negative bending grouting hole is easy to jam so it increases a lot of difficulty for negative bendingprestressed duct grouting. This article taking Dongchang highway Censhui grand bridge negative bending moment construction as anexample summarizes the problems existing in T beam negative bending moment construction and inspection measures has obtained thegood construction effects accumulated experience to solve such process construction in the future.院公路T 梁 负弯矩压浆 处理措施Key words highway T beam hogging moment grouting treatment measures中图分类号院U448.21 文献标识码院A 文章编号院1006-4311（2014）01-0104-020 引言施工质量是企业的根本，现场管理是企业管理最重要的工作。近年来，在生产经营规模急剧扩张，但是，由于任务量大，技术人员及现场管理人员不足或现场管理人员失职造的质量问题也时有发生，如桥梁T 梁施工中，负弯矩压浆孔道由于施工种种原因容易堵塞，从而造成弯矩压浆不密实，本文某某高速公路一特大桥负弯矩施工为例，有关于T梁负弯矩压浆不密实的处理方法进行了分析和总结。
