Glue injection type suspension bridge main cable
The invention provides a glue injection type suspension bridge main cable which can effectively improve the temperature field distribution condition of the suspension bridge main cable and reduce maincable damage caused by unbalanced stress distribution between cable strands in the main cable, so that the service life of the main cable and the suspension bridge is prolonged. According to the scheme, the glue injection type suspension bridge main cable comprises a sheath, cable strands and heat-conducting glue, and the heat-conducting glue fills the sheath and between the cable strands. The cable is characterized in that the heat-conducting glue filling the sheath is tightly bonded with each cable strand so as to isolate redundant air in the sheath. Air is a poor conductor of heat, and seriously hinders heat transfer between cable strand contact surfaces. The heat-conducting glue has excellent heat-conducting property, gaps among the cable strands are filled with the heat-conducting glue, and air is extruded out of contact surfaces among the cable strands, so that the heat conduction quantity can be increased to the maximum extent, and the temperature difference among the cable strands is greatly reduced.
本发明提供一种注胶式悬索桥主缆，本发明能有效地改善悬索桥主缆温度场分布情况，减少由于主缆内部索股间应力分布失衡而导致的主缆损害，从而延长主缆以及悬索桥的使用年限。方案是：一种注胶式悬索桥主缆，包括：护套、索股、导热胶；所述导热胶填充于所述护套之内、所述索股之间。其特征在于：填充于护套内的导热胶紧密地与各根索股粘合，从而隔除护套内多余的空气。空气是热的不良导体，严重阻碍热量在索股接触面之间的传递。导热胶本身具有优异的导热性能，将导热胶填充索股之间的间隙，将空气挤出索股之间的接触面，使热传导量可以增到最大，使索股之间的温差大大减少。
