Problems solved by technology
[0002] With the continuous development of our country's social economy, the urban population is growing rapidly, and the per capita living area is correspondingly reduced, which makes the urban land area gradually change from flat development to three-dimensional space development, that is, in the limited urban flat space, vigorously develop and utilize urban areas. In underground space, with the increasing excavation depth, underground engineering will face problems such as high ground pressure and high water pressure, which also makes traditional support methods unsuitable for deep underground environments. For this reason, new support methods need to be introduced
[0003] Among many urban underground space support methods, the row pile method is widely used for its advantages of simple construction, convenience, and low cost. However, due to the limitations of the connection between piles and pile defects, the The water-stop performance is poor, and it is not suitable for deep underground projects, especially deep projects rich in water

Description
technical field [0001] The invention relates to the technical field of waterproofing in underground spaces, in particular to an inter-pile freezing structure in deep underground spaces and a construction method. Background technique [0002] With the continuous development of our country's social economy, the urban population is growing rapidly, and the per capita living area is correspondingly reduced, which makes the urban land area gradually change from flat development to three-dimensional space development, that is, in the limited urban flat space, vigorously develop and utilize urban areas. In underground space, with the increasing excavation depth, underground engineering will face problems such as high ground pressure and high water pressure, which also makes traditional support methods unsuitable for deep underground environments. For this reason, new support methods need to be introduced. [0003] Among many urban underground space support methods, the pile row met...
