1 问题的提出 在工程施工中,经常会遇到大型深基坑排水问题,此时,水处理的恰当及时,对保证工程进度和工程质量,减少工程投资至关重要。 小口径沉降井是一种垂直的圆形结构物,通常预制成钢筋混凝土圆井管,施工时从井管中间挖土,同时排水,使井管失去支撑而下沉,直到设计深度。这种小口径
1 raised the problem In the construction of the project, often encountered large-scale deep foundation pit drainage problems, this time, the proper and timely water treatment, to ensure project progress and project quality, reduce project investment is essential. A small diameter settlement well is a vertical circular structure, usually prefabricated into a reinforced concrete round well pipe. During construction, excavation from the middle of the well pipe while draining water causes the well pipe to lose support and sink until the design depth. This small caliber
