强风吹落午门墙皮 故宫排查安全隐患

　　昨天上午近11时，故宫午门城台部分墙面在强风中发生脱落，脱落墙面未造成人员受伤。相关视频在网上流传后引起各方关注。

　　情况发生后，故宫立即启动安全应急预案，疏散观众，封护现场，并派出古建筑应急抢修施工队进行应急抢修处理，包括对空鼓脱落墙面的清理，对有脱落危险的墙皮进行预先铲除。因冬季气温较低不适宜古建筑墙面施工，故暂不进行抹灰操作，只做刷浆处理，以保证墙面的整体观感协调。待到适宜施工的季节，再按照传统修缮做法重新铲抹刷浆。

　　北京青年报记者了解到，故宫古建筑及城台墙面的修缮都依据传统做法，即在古建墙体砖基层上钉麻揪、抹靠骨灰、刷红浆。但因古建筑建成年代久远，经过长年累积，墙体和城台内部含水率较高，室外温度低时会出现冻胀现象，导致墙面表层出现局部空鼓情况。根据北京市气象局于12月23日发布的大风蓝色预警显示，受冷空气影响，当日北京市有偏北风4~5级，阵风达7级左右。鉴于冬季早晚温差大、室外温度低，冻胀现象造成的墙面表层空鼓情况尤为明显，故风大时极易使空鼓的墙皮与基层剥离、脱落。

　　针对上述保存现状，故宫已制定《故宫古建筑及城台墙面维修预案》，采取了日常巡视检查、应急抢修处理、墙面岁修保养等监测保护措施。一是对故宫院内古建筑及城台墙面进行长年监测和日常巡视，遇有出现局部空鼓现象的墙面，根据保存现状程度，严重时及时进行应急处理，保证墙面观感和观众参观安全；一般时列入墙面岁修保养计划，逐年实施墙面日常保养工程。二是遇有保存现状严重空鼓、随时有脱落危险的墙面，专设故宫古建筑应急抢修施工队伍负责进行应急抢修处理。三是对日常监测和巡查后列入岁修保养计划的墙面，按照计划在适宜古建筑墙面施工的季节及时组织人员、按照传统做法进行墙面岁修保养。

　　故宫在此提醒广大观众，极端天气下请注意出行安全。近期，故宫将对院内其他类似安全隐患进行全面排查，抢修处理，保障参观环境的全面安全。
