In view of the above characteristics, a new joint waterproof structure of adhesive anchor sealing type for super large frame box culvert is developed in this paper. The new joint waterproof structure adopts the method of reserving anchor slots in the fabrication stage of the front and the rear frame box culverts, and uses the new rubber elastomer to form the middle buried water-stop with expansion function between the joint of the front and the rear frame box culvert.展开 关键词：Joint waterproofing Large section box culvert Anchor bonding and sealing 年份：2022 |
