Abstract

The precast panel is especially for use in water-bearing ground, serving as excavating shoring and the permanent lining. Inner (1) and outer (2) layers sandwich a water-proofing membrane (3), the outer layer projecting beyond the inner to seat and protect a projection of the membrane (3), this latter being again protected on its exposed face by temporary shields (4). These shields span between and tie inner and outer layers and edges of abutting panels are joined using tongues (7) and grooves (6) in the outer layer (2), and the rectangular gap between panels then receives an overlapping strip of membrane (10) followed by concrete infill (11). Reinforcement (5) projects from the inner layer into the joint and temporary ties can be used during excavation.
