深圳鼎和大厦基坑工程基岩裂隙灌浆施工技术研究

Research on Construction Technology of Grouting in Bedrock Fracture of Deep Foundation Excavation of Dinghe Plaza

以深圳市鼎和大厦基坑工程为例,对基岩裂隙灌浆施工技术进行了深入研究。首先根据该工程的地质条件及水文条件,对施工降水将给场地周边环境带来的影响进行分析,阐述了采取基岩裂隙灌浆止水措施的必要性;然后结合工程实际,提出了适合本工程的裂隙灌浆施工技术,并对主要施工工艺及流程,制浆、灌浆等技术进行了重点研究。论文提出的施工技术和方法可为同类工程施工提供参考。

Regard a foundation excavation as example of Shenzhen Dinghe Plaza, detail research has been done into the bedrock fi-acture grouting technology. First, according to the geological conditions and hydrological conditions of the engineering, the affects brought by construction precipitation to the venues sun＇ounding has been analyzed, and elaborated the need to take the bedrock fissures grouting sealing measures. Then, combine to the engineering practice, grouting technology for this project has been proposed and major construction techniques and processes, pulping and grouting technology has been studied in deeply. The construction techniques and methods put forward can provide a reference for the construction of similar projects.
