In 2007-2008, we undertook the development project of Xiamen Xiang'an Subsea Tunnel (a key project of the National 863 Project) and the built-in high-pressure rubber diaphragm of the deluge valve of the fire protection system! After more than a year of hard study and repeated tests, it successfully passed the inspection and acceptance of Xiamen Fire Research Institute, with a two-way pressure of 6MPa without blasting for 259,200s, creating the highest record of two-way pressure of fabric cloth diaphragms at home and abroad. At the end of 2009, the fire protection system of Xiang'an submarine tunnel was successfully tested, and won the Science and Technology Innovation Award of China.
