本工程位于山东省菏泽市,先期建设的高层住宅地下室结构已施工完成,后增加连体地下车库,车库与高层住宅地下室结构需增设逃生通道,因高层住宅地下室结构已施工完成,且未给新增车库预留任何防水接口措施,现需在高层住宅地下室结构的外墙处进行事后开孔,设置为消防使用的逃生通道连接两座地下建筑,工程技术难点在于解决两座建筑的防水对接问题,且没有同类工程实践经验可借鉴参考。 The project is located in Heze City, Shandong Province. The prefabricated high-rise residential basement structure has been completed and the escape tunnel has been added after the construction of the basement of the underground garage, garage and high-rise buildings. As the basement structure of the high-rise residential house has been completed and has not been newly constructed Increased garage Reserved for any waterproof interface measures, it is required in the high-rise residential basement structure of the outer wall at the post-opening, set to fire escape routes used to connect two underground buildings, engineering and technical difficulties is to solve the two buildings waterproof docking problem , And no similar engineering practice can learn from reference.
