碎石注浆桩是20世纪90年代以来,综合砂石桩、高压注浆两项技术组件发展起来的一种新型的地基处理方法。由于它具有的施工设备比较轻便,易于满足施工场地的要求,而且施工时候噪音较小,对于施工环境造成的影响较小;并且碎石灌注浆具有较高的承载能力,而且其造成比较简单,使得技术达到快速发展的目的,特别是广泛应用于高速公路桩的制作,在铁路建设中得到了普遍的应用。本文主要是对碎石灌注浆的施工原理以及技术进行了详细的阐述。
Gravel grouting pile is a new type of foundation treatment developed since the 90s of the 20th century with integrated technology of gravel piles and high-pressure grouting. Because of its relatively light construction equipment, easy to meet the requirements of the construction site, and less noise during construction, the impact on the construction environment is small; and gravel grouting has a high carrying capacity, and its relatively simple , Making the technology to achieve the purpose of rapid development, especially widely used in the production of highway piles, has been widely used in railway construction. This article is mainly on the gravel grouting construction principles and techniques described in detail.
