碎石注浆桩是一种引进注浆技术的软基处理新方法,它是利用钻机按设计直径,钻进至设计深度成孔,放入注浆管后,投放石料。在投放石料的过程中,用注浆管放水清洗钻孔,石料投放完成后进行并进行注浆,使石料固结成桩。本文针对施工现场中对于公路工程中的碎石注浆桩施工进行详细的阐述。
Gravel grouting pile is a kind of soft grouting technology to introduce a new method of grouting technology, it is the use of drilling rig according to the design diameter, drilling into the design depth into the hole, into the grouting pipe, put stone. In the process of throwing the stone, the grouting pipe is used to drain the water to clean the hole, the stone is put into operation and grouted, so that the stone is consolidated into a pile. In this paper, construction site for highway engineering gravel grouting pile construction in detail.
