Abstract:The form of waterproof curtain wall in deep foundation construction in Wuhan primarily adopts the diaphragm wall directly seated onto the bedrock. However, leakage always occurs in the construction of diaphragm walls owing to their perpendicularity. Meanwhile, the cost is much higher. The case study concerning the building of Wuhan Yangtze River Shipping Center is introduced. As a waterproof technique the constructability of this technique is investigated including the quality control and seepage of the wall. Through comparison, the TRD technique has sound waterproof properties, which can be constructed in advance. Meanwhile, this technique can reduce the project construction period significantly and more economic than diaphragm wall. This case study can be an option in waterproof technique in construction of deep excavations.
