中国南海三沙永乐群岛新建2座可抗17级风的灯桩

2015-10-22 19:25:08   新华社

记者从南海航海保障中心西沙南沙航标处获悉,三沙市永乐群岛的晋卿岛和羚羊礁筐仔沙洲两座可抗风17级的灯桩21日建成竣工。

据了解,晋卿岛和羚羊礁筐仔沙洲灯桩基座上部灯桩材料为超高分子量聚乙烯,柱管直径0.8米,高度6米,灯桩寿命50年,色泽寿命15年,耐晒等级8级,抗风等级17级,光源设备海上可视距离大于5海里。

据介绍,目前,我国三沙辖区目视航标服务严重不足,许多岛屿都没有可供使用的民用海图资料,直接影响着三沙市政府的区域管理、开发建设和航行作 业船舶的安全监管。西沙航标处技术人员还将继续开展岛礁地质地貌勘测,采集西沙水域拟建岛礁地质样本,为下一步灯塔(桩)建设采集翔实的勘测数据。 (记者赵颖全)
