轻质泡沫混凝土换填施工工序研究

Research on Lightweight Foam Concrete Replacement Construction Procedure

轻质泡沫混凝土具有安全环保、轻质、保温、防火性好、耐久性强等优点,广泛使用于屋面保温、防火隔离带、换填减荷等工程领域。换填减荷主要利用了轻质泡沫混凝土的轻质特性,需严格控制施工后混凝土的吸水量,对防水结构的施工有较高要求。针对天津西站1号线换填工程,对其施工顺序进行深入分析。

Lightweight multi-purpose concrete has many advantages ：environment safety,light weight,thermal insulation,favorable fireproofing and endurance,so used in building thermal insulation,the security fence of fireproofing,soil exchange reducing. Exchange reducing take light weight advantage of lightweight multi-purpose concrete,to control the flow of wicking and the construction of waterproof severely. The article analyzes the order of soil exchange method in the line 1 Tianjin west railway station.
