前言随着西部大开发进程的不断深入,建筑工程施工量不断增大,关系建筑物、构筑物结构强度的砼现浇板在施工中出现缺陷后如何补强,目前在结构底部由于浇筑深度较大,底部钢筋过密,容易因施工漏振而产生蜂窝、露筋、孔洞等现象,灌浆处理也比较困难。如何通过相关技术处理,使之在不破坏板面的情况下达到设计强度,成为一 Preface With the continuous deepening of the development of the western region, increasing construction work, the relationship between the structure of buildings, structural strength of concrete cast-in-site construction defects in the how to reinforce the current structure at the bottom due to the pouring depth , The bottom of the steel bar is too close, it is easy to produce honeycomb, dew, holes and other phenomena due to the construction of leakage, grouting is also more difficult. How to deal with through related technologies, so that it can achieve the design strength without damaging the board, become a
