近年来,由于经济的快速发展,地下工程行业也呈现出蓬勃发展的趋势。其中深基坑的开挖工程受到越来越多的重视。深基坑开挖的降排水属于深基坑的工程难点,降排水的质量直接对深基坑工程的质量产生影响。本文主要分析了承压水对于深基坑造成的危害,并对深基坑开挖降排水施工前的准备,深基坑开挖的降排水施工和深基坑开挖降排水的意义进行探究。
In recent years, due to the rapid economic development, the underground engineering industry has also shown a trend of vigorous development. The excavation of deep foundation pit is receiving more and more attention. Dewatering of deep foundation pit excavation belongs to engineering difficulty of deep foundation pit. The quality of drainage water directly affects the quality of deep foundation pit engineering. This paper mainly analyzes the harm of confined water to the deep foundation pit, and explores the preparation before water drainage construction of deep foundation pit excavation, the water drainage and drainage construction of deep foundation pit excavation and the drainage and drainage of deep foundation pit excavation.
