T形沉井的基础及下沉稳定性施工设计

Foundation of T-type Open Caisson and Design of Sinking Stability Construction

沉井是修建深基础、地下构筑物所广泛应用的施工方法之一。该文通过对某污水处理厂粗格栅及进水泵房T形沉井(构筑物)基础的下沉施工设计计算、施工实践,解决了T形沉井制作及不排水法下沉施工中的稳定性问题。

The open caisson is one of the construction methods widely used in the construction and repairing of deep foundation and underground structures. The article introduces the sinking construction design, calculation and construction practice of the coarse screen of a wastewater treatment plant and the Ttype open caisson (structure) foundation of influent pumping house to solve the stability problems in the manufacture and the nodrainage sinking construction of the Ttype open caisson.
