Construction of Diaphragm Wall for Seawater Intake Pump House
Diaphragm walling refers to the in-situ construction of vertical panels by means of deep trenching. Of all the embedded retaining walls, diaphragm wall shoring system possesses the best water retaining properties. It can be used as temporary shoring during excavation phase and as permanent retaining wall or a load bearing wall in permanent stage. Retention system using diaphragm wall was used to build intake well, chosen for the present study. Project site consists of mixed soil conditions of medium plastic clay/silty clay followed by silty sand. Design & construction aspects of permanent diaphragm wall with an optimized thickness of 1200 mm and 28 m deep is discussed in this paper. Depth of excavation is about 18.5 m supported with 4 levels of internal reinforced concrete beams, sealed with bottom raft and beams connected at top. This paper illustrates important aspects of design and execution phases. In addition, performance of wall due to methods of analysis, influence of water table, over excavation and drained and undrained behavior of soil is covered.
