Protection construction method for cultural insurance building close to ultra-deep foundation pit
The invention relates to a cultural insurance building protection construction method close to an ultra-deep foundation pit, and belongs to the technical field of foundation pit excavation. According to the method, before construction of the ultra-deep foundation pit, a wall body of the cultural and cultural insurance building is reinforced, then a strip-shaped foundation of the cultural and cultural insurance building is changed into a raft foundation, then anchor rod static pressure piles and emergency hole pressing piles are driven into a raft, and then a temporary steel frame structure which is internally supported and externally hooped is applied to the upper portion of the wall body of the cultural and cultural insurance building, so that construction of the ultra-deep foundation pit can be conducted. And after the ultra-deep foundation pit structure is closed, the temporary steel frame structure is dismantled. According to the method, the bearing capacity and stability of the cultural insurance building foundation are improved, and the cultural insurance building is effectively protected; and construction of the ultra-deep foundation pit can be smoothly completed on the premise that cultural relics are not damaged, the construction quality and safety of the ultra-deep foundation pit are guaranteed, and the appearance and historical value of the cultural relics are effectively protected.
本发明涉及一种近接超深基坑的文保建筑保护施工方法，属于基础坑挖方技术领域。该方法在超深基坑施工前，先对文保建筑的墙体进行加固，然后将文保建筑的条形基础改成筏板基础，接着在筏板上打入锚杆静压桩和应急压孔桩，再在文保建筑的墙体上部施加内撑外箍的临时钢架结构，这样就可以进行超深基坑施工了。在超深基坑结构封闭完后拆除临时的钢架结构。该方法不仅提高了文保建筑基础的承载能力和稳定性，有效地保护了文保建筑；而且在不破坏文保建筑的前提下可以顺利完成超深基坑的施工，既保证了超深基坑的施工质量和安全又有效地保护了文物的外观和历史价值。
