上海地区软土地层中施工的工程地基基础,大量采用钻孔灌注桩。每根灌注桩的钢筋笼有几节焊接而成。钻孔灌注桩施工结束后,如何检测其钢筋笼长度和焊接质量是一个难度很大的问题,本文介绍采用高精度基础桩现场诊断仪和地质雷达仪检测钻孔灌注桩钢筋笼长度的方法及效果。
In Shanghai, a large number of bored cast-in-place piles are used for the foundation of the engineering foundation in the construction of soft ground. The reinforcing cage of each cast-in-place pile is welded in several sections. After the construction of the bored pile, how to detect the length of the reinforcement cage and welding quality is a very difficult problem. This article describes the method of testing the length of the reinforcement cage of the bored pile using the high-precision foundation pile field diagnosis instrument and geological radar instrument. effect.
