在我国城市化建设水平不断发展的今天,地下工程得以快速的建设发展,进而促进了基坑工程向着更大更深的方面发展。而在其施工中钻孔咬合桩本着其自身的优势,在高层建筑工程中的深基坑工程、地铁工程以及道路下穿线的深基坑工程中得到了很好的应用。而钻孔咬合桩的施工其质量安全保障的前提是所灌注的超缓凝混凝土是否满足相关的设计以及施工要求。但是由于超缓凝混凝土的施工中期配制比较复杂,并且施工的影响因素也比较多,所以就导致很多安全隐患的出现。基于此,本文将着重分析探讨超缓凝混凝土在钻孔咬合桩中的应用,以期能为以后的实际工作起到一定的借鉴作用。
Today, with the continuous development of urbanization in our country, the underground engineering can be rapidly constructed and developed, which further promotes the development of the foundation pit engineering to a larger and deeper level. In its construction, bored piles have been well applied in deep foundation pit engineering, metro engineering and deep foundation pit under road threading with its own advantages. The prerequisite for the quality and safety of the bored pile construction is whether the infused super-retarding concrete meets the relevant design and construction requirements. However, due to the construction of super-retarding concrete mid-term preparation is more complicated, and the impact of construction factors are more, it will lead to a lot of potential safety problems. Based on this, this article will focus on the analysis of the application of ultra-retarding concrete in bored piles, with a view to the future practical work for some reference.
