随着我国经济建设的快速发展,越来越多的地铁如雨后春笋般的出现在各大城市中,在缓解城市交通压力、促进经济发展方面起着非常大的促进作用,因此保证地铁工程的施工质量是非常重要的,这首先就需要做好地铁深基坑的降排水施工技术,从而不断提高地铁工程土壤的强度。本文主要对地铁深基坑降排水施工技术进行了探讨。 With the rapid economic development in our country, more and more MTRs have mushroomed in major cities, playing a very big role in alleviating urban traffic pressure and promoting economic development. Therefore, it is necessary to ensure the construction of subway projects Quality is very important. First of all, it is necessary to do well in the construction technology of lowering the depth of the deep foundation pit in the subway so as to continuously improve the strength of the soil in the subway project. This paper mainly discusses the construction technology of lowering drainage in deep foundation pit of subway.
