摘要
按照当前现代交通业的发展进程,大多数涉及预应力钢筋混凝土构造物废除新建、扩容美化施工需求持续增长,预应力钢筋混凝土构造物废除或重建施工采用保守施工工法、机具面临施工条件复杂、安全风险极大、对外协调难度大、利润低等特点,而施工管理必须满足当地有关法律法规、最新规范及环水保要求.因此迫切需要新工艺解决预应力钢筋混凝土构造物废除遇到的各种难题.
Abstract
According to the current development process of modern transportation industry,the demand for the abolition of new construction,expansion and beautification of most prestressed reinforced concrete structures continues to grow.The demolition or reconstruction of prestressed reinforced concrete structures adopts conservative construction methods and equipment,and has the characteristics of complex construction conditions,high safety risks,difficulty in external coordination,and low profits.Moreover,construction management must comply with local laws and regulations,the latest standards,and environmental and water protection requirements.Therefore,there is an urgent need for new technologies to solve various difficulties encountered in the abolition of prestressed reinforced concrete structures.
