本文介绍的钻吸排土下沉施工技术是一项解决不排水沉井水中作业难的新工艺,为不排水沉井提供了一项高工效、高速度的新施工方法。通过多年来的工程实践,已显示出该工法对深大型沉井下沉施工的优越性,既能防止下沉中流砂、涌土突沉等现象的发生,也能有效地控制沉井周围地表的沉降,确保了下沉施工质量,可广泛应用于软土地层条件中的不排水沉井施工。
Described in this article, drilling and sinking soil subsidence construction technology is a new technology to solve the problem of non-draining caisson water is difficult to work for the undrained caisson provides a high work efficiency, high speed new construction methods. Through years of engineering practice, it has been shown that this method has the superiority of the construction of deep caisson, not only preventing the sinking of midsummer and influx of soils, but also effectively controlling the surface of the caisson Settlement, to ensure the quality of construction sinking can be widely used in soft soil conditions in the construction of undrained caisson.
