目前在建筑基坑工程中,土钉墙支护经济实用、安全可靠的优势逐渐得到越来越广泛的运用。土钉墙支护是近年来发展起来用于土体开挖和边坡稳定的一种新型挡土结构。土钉墙是由天然土体通过土钉就地加固并与喷射混凝土面板相结合,形成一个类似重力挡墙以此来抵抗墙后的土压力,从而保持开挖面的稳定,这个土挡墙称为土钉墙。由于其具有经济、施工快捷等优势,在我国得以迅速推广应用。土钉墙是采用土钉加固的基坑侧壁土体与护面等组成的支护结构。本文就土钉墙支护施工工法进行了研究。
At present, in the construction of foundation pit projects, the advantages of economical, practical, safe and reliable soil nailing wall support have gradually been applied more and more widely. Soil nailing wall support is a new type of retaining structure that has been developed in recent years for soil excavation and slope stability. The soil nailing wall is reinforced by natural soil through soil nails and is combined with the sprayed concrete panel to form a gravity retaining wall to resist the earth pressure behind the wall, so as to maintain the stability of the excavation surface. This soil retaining wall Soil nail wall. Because of its advantages of economy, quick construction, etc., it can be quickly applied in our country. The soil nailing wall is a supporting structure composed of earthen-nail-reinforced sidewalls of the foundation pit and retaining surfaces. In this paper, the soil nailing wall construction method was studied.
