某车间的面积为5400平方米,共有82个厂房柱基础。原设计为单爆桩基普通配筋承台,在施工时,将66个厂房柱基础改为联爆桩基预应力芯棒配筋承台。由于减少了柱距,采用了预应力芯棒配筋,节省混凝土量236米~3,少挖土方量583米~3,承台内的配筋 The workshop has an area of ​​5,400 square meters and a total of 82 building pillars. The original design was a single explosive pile foundation ordinary reinforcement bearing platform. In the construction, 66 pillars of the factory building were replaced by the joint piles of pre-stressed core rods. Due to the reduction of column spacing, pre-stressed mandrel bar reinforcement is adopted, saving 236 m~3 of concrete volume and 583 m~3 of less earth-moving capacity.
