Abstract:
Drainage systems in pressure-relieved tunnels are used for the permanent concentrated drainage of ground water. In order to ensure that the tunnel structures function properly, these drainage systems must be maintained and cleaned at regular intervals. Intensive cleaning can also cause damage to the drainage pipes themselves, especially in the case of hard precipitations in the pipes that are difficult to remove. Depending on the type of damage, these defective pipes can even pose a threat to the entire structure in the worst case. For this reason, it is essential to repair damaged drainage pipes promptly. A number of methods that can be used for trenchless pipe rehabilitation are known from the field of municipal water management and sewage. The problem with existing methods is that they usually do not consider the specific tunnel construction aspects, such as the required drainage effect, limited access via cleaning shafts, no complete shut-off of the drainage water, more intensive and mechanical cleaning work compared to municipal water pipes, and more.
