Abstract

Abstract

National Speed Skating Oval is the landmark of the 2022 Winter Olympic Games, and the waterproofing of the unitary roofing system for the flexible cable net area is a key issue which needs to be solved. Firstly, based on the relevant cases, the mechanical properties and micro failure mechanism of common polymer waterproofing membrane were analyzed, including internal enhanced TPO, homogeneous EPDM and EPDM pressure-sensitive self-curing flashing. The test results showed that EPDM had better dimensional stability than TPO, and with the increase of curing time, the performance of EPDM pressure-sensitive self-curing flashing material gradually started to show the elastic performance of finished EPDM membrane from its initial plasticity, completely met the requirements of waterproofing membrane. Finally, EPDM membrane with self-curing flashing was selected for the waterproofing of National Speed Skating Oval, and some suggestions on the vulcanization research of the self-curing flashing materials were put forward.
