- Abstract:
- According to the production demand of the expansion joint repair in a large main canal in alpine area of northern Xinjiang， the following work steps had been performed. First of all, the leakage causes of canal expansion joint were found out. Secondly, on the basis of field test and engineering experience, an eco-technical comparison of waterstop materials was carried out. The working properties of the polyurethane sealant were studied under special construction environment, such as low temperature, humidity and unclean of the joint surface. Finally, the construction technology appropriate to the actual situations was identified. A mending option was successfully applied in practice, which provides a good reference for other projects in similar construction environment.
