AI Technical Summary

Technical Problem

Traditional blasting and mechanical demolition techniques are limited by the collapse space and surrounding environment, making them ineffective for demolishing high-rise buildings under dense building complexes, resulting in safety hazards and low efficiency.

Method used

The high-rise building was demolished in sections from top to bottom using an attached lifting scaffold fixed to the lower walls of each floor. The building area was pre-cut, and the building was demolished by inward or in-situ collapse blasting. The amount of explosives was gradually reduced layer by layer. Small crushing machinery was used to transport the blasting residue out through the elevator shaft, and the building structure was demolished section by section.

Benefits of technology

It improved demolition efficiency, reduced safety distances, lowered noise and dust pollution, ensured the safety of demolition operations, and adapted to complex urban environments.

Abstract

本申请提供一种高层楼房自上而下分段爆破拆除方法,包括:根据待拆楼房的高度将其竖向分段,同时根据高层楼房平面将其对称分为若干个区域,对待拆楼房进行切割;对于每一个待拆楼段区域,采用内向坍塌或原地坍塌爆破方案,在待拆楼段区域楼层的承重立柱上钻凿炮孔并装填炸药雷管;爆破拆除第一段楼层第一区域楼房结构,继续爆破第一段楼层其它区域楼房结构,循环运用上述方式,拆除所述楼房剩余段落的结构。本申请实现了高层楼房自上而下分段爆破拆除,突破了密集建筑群受限空间条件下高层楼房不能实施爆破拆除的技术瓶颈,显著提高了拆除的作业效率和安全性,克服了传统机械拆除方式噪音、粉尘污染持续时间长、社会影响大等问题。
