随着振冲法这一地基加固的处理技术的迅速发展和普及,对碎石桩加固软弱地基效果的检验,越来越显得重要,这是大家关心的问题。最常用的办法是按一定的操作程序和工艺标准制桩,然后抽样进行检验。由于土类的不同,其检验的手段和办法也不一样。我们在用碎石桩加固软弱粘性土地基中,重点强调施工工艺和施工操作。对于加固后的技术效果,是用动力触探(N_(63.5)) 来进行质量检查的。即在碎石桩的中心进行触探,用相同的贯入能量,从贯入度的大小来了解碎石桩体的密实度,可鉴别碎石桩体中
With the rapid development and popularization of vibroflotation, a technology for strengthening foundations, it has become increasingly important to test the effect of gravel piles on reinforcing weak foundations. This is a matter of concern to everyone. The most common method is to make piles according to certain operating procedures and process standards, and then sample for inspection. Due to the different types of soil, the methods and methods of inspection are not the same. We emphasize the construction process and construction operations in the use of gravel piles to reinforce weakly viscous ground. For the technical effect after reinforcement, the quality inspection was performed using dynamic penetration (N_(63.5)). In the center of the gravel piles, a penetration test is performed. With the same penetration energy, the density of the gravel piles can be known from the degree of penetration to identify the gravel piles.
