“降层拆除法”是以小型挖掘机配备液压锤吊至高层建筑楼面进行机械拆除为主、人工风镐拆除为辅的高层建筑楼体拆除方法。待楼体拆除至机械能够在地面上进行作业后,再将小型挖掘机移走,采用大型挖掘机配备长臂液压剪为主、液压锤辅助在地面进行解体拆除。结合工程实际,介绍了其施工工艺及安全措施,达到了理想的效果,适用于场地狭窄、周边环境比较复杂,且对爆破拆除有限制的高层建筑楼体拆除工程项目。
“Demolition method” is a small excavator equipped with hydraulic hammer hanging to the high-rise building for mechanical demolition of the main demolition, manual picks demolition of high-rise building demolition method. After the building is dismantled and the machinery can be operated on the ground, the small excavator is removed again. A large excavator is equipped with long-arm hydraulic shears, and the hydraulic hammer assists disassembly and disassembly on the ground. Combined with engineering practice, the construction technology and safety measures are introduced, and the ideal effect is achieved. It is suitable for the demolition of high-rise building demolition projects with narrow space and complex surrounding environment and limited blasting demolition.
