另据了解，1号机库大厅网架由3309个焊接球与12124根圆管杆件拼装而成，拼装难度同样极大。为保证 拼装精度，施工现场引入机器人三维扫描技术，使钢结构测量效率提升5-10倍，扫描速度达976,000点/ 秒，扫描精度±1毫米，同时依托云锦智建自主研发的睿瓴云平台，进行钢结构拼装实时监测，确保拼 装工作高效、安全推进，也为此次提升节点的顺利完成做好了必要的前期准备。（编辑：李佳洹 校 对：陈虹莹 审核：韩磊） 机库的钢网架屋盖顺利提升至设计位置（云锦智建供图） 该机库的钢网架结构，是机库的"钢铁穹顶"，在设计精度、吊装技术、安全管控等方面，均为行业高难 度水平。为确保此次升顶，云锦智建此前已顺利完成一阶段网架提升，当时将钢网架提升4.4米高度、 并与大门桁架连接，当时的提升重量约为3814吨，通过作业充分验证了技术方案的科学性与可行性，为 本次实现关键节点奠定了坚实基础。 本次二阶段升顶，是在一阶段提升基础上，进一步开展机库屋盖整体提升，提升高度为21.4米，提升重 量约为6029吨。施工现场共设置了24个柱顶提升点，配备8个提升泵站与38个液压器，在控制系统联动 下，历经10小时，屋盖顺利提升至设计位置。 ...

（来源：中国航空报） 许自胜 航空城阎良的好几条街道上，都长着高大粗壮的法国梧桐树。这些法桐拔地参天、形态奇特、浓荫蔽日，四季皆景。 有一棵高耸的法桐尤为奇特，我绕着树看，从树身看到树顶，越看越有兴致，竟像秦腔戏"苏武牧羊"中的苏武，年迈的苏武衣衫褴褛，站在风雪中执鞭放 羊，一片茂密的树冠极像苏武满头乱发而眺望远方。 清明节前后，法桐的枝头开始冒出嫩绿的新芽，短短几天，嫩芽就像小小的手掌轻轻展开，阳光透过枝叶洒下斑驳的光影，路面上形成一片片跳动的光斑， 微风吹过，光斑随风摇曳，给人一种灵动和温暖的舒服。 酷热的夏天，蝉鸣悠长，法桐便开始展现出铺天盖地的生命力。走在延安街上，抬眼望去，街道两边的法桐不论什么姿态，头顶都层层叠叠地绿荫如盖，如 手掌般的叶片在长长的树枝间相互牵手，勾肩搭背，紧密地亲吻在一起，把街中心搭盖成一里多长的一条阴凉的隧道。三伏天烈日炎炎，火辣辣的太阳被绿 叶温柔地承接和过滤，洒下一地"碎金"。此刻你无论步行还是驾车，都能感到一丝难得的清凉，仿佛那疲惫的身心在宁静的海洋里徜徉。 最惹眼的两排法桐在区政府所在地延安街上。你若站在延安街北头向南眺望，两排身躯高大，枝干遒劲，皮肤灰白皱裂的法桐一直 ...
