摘 要: 介绍了预制综合管廊接口密封圈材料的选择,并基于综合管廊使用环境,选取了三元乙丙橡胶作为主要密封材料。对选取的材料进行了老化试验,得到了压缩永久变形值和老化系数,并计算了老化时间,验证了所使用的材料满足相关耐久性要求。
Abstract: The selection of sealing ring material for prefabricated integrated pipe gallery was introduced. Based on the using environment of comprehensive pipe galleryand, the three ethylene propylene rubber was selected as the main sealing material. The aging test of the selected material was carried out, and the value of permanent compression deformation was obtained. The aging time was calculated, and the material could meet the relevant durability requirements.
