A precast box culvert for telecommunication lines, made in segments of about 2m long, has many connections through the whole length. These connections are very vulnerable from the irregular settlement of the foundation and the external loads. The proposed precast box culvert has an inclined side walls to resist shear forces by settlements and uses a polyethylene gasket and bolts at connections for water-proof and tight connection. In order to verify its performance, the structural safety, the behavior of connection parts and the water-tightness of this new box culvert tested in lab before it is applied in field. The results show that it has a high load carrying capacity and satisfactory behavior at the connection.
