河北涿鹿化肥厂造气厂房是二层外框架式结构,面积1000米~2。主要承重结构是浆砌砖柱,楼板、横梁、纵梁和圈梁都是用钢筋混凝土整体浇注的。厂房全长70米,跨度9.5米,高度10米。爆破长度53.37米,要求保留部分不得破坏。厂房东侧距动力线4米;南侧距三层碳化厂房5米,有6条输气管道沿南墙通过,在爆破时必须保证其安全;西侧距动力线4米;西北侧距压缩机厂房和冷却池8米,北侧22米处是联合车间。为确保造气厂房保留部分免遭破坏,首先用人工从上至下拆除0.2~0.3米宽的隔离带,切断与爆破部分的联系。为保证南侧碳化厂房和输气管道等设施的安全,确定向北侧定向倾倒。由于该厂房主要承重构件是砖柱,要用足够的药量彻底炸毁底层
Hebei Zhuolu Chemical Fertilizer Plant is a two-story frame structure with an area of 1,000 meters~2. The main bearing structure is a mortar and brick column. Floor slabs, beams, longitudinal beams and ring beams are all integrally cast with reinforced concrete. The plant is 70 meters long with a span of 9.5 meters and a height of 10 meters. The blasting length is 53.37 meters and the reserved part must not be destroyed. The east side of the workshop is 4 meters away from the power line; the south side is 5 meters away from the three-story carbonization plant and 6 gas pipelines pass along the south wall. The safety must be ensured during blasting; the west side is 4 meters away from the power line; The factory building and the cooling pool are 8 meters, and the 22 meters to the north is the joint workshop. In order to ensure that the remaining part of the gasification building is protected from damage, firstly remove 0.2 to 0.3 meters wide strips by hand from top to bottom and cut off the connection with the blasting part. In order to ensure the safety of facilities such as the carbonization plant and the gas transmission pipeline on the south side, it is determined to dump toward the north side. Since the main load-bearing building of the factory is a brick column, it is necessary to blow up the ground thoroughly with enough doses.
