大型圆筒形构筑物悬挂半逆作施工工艺

Suspension Semi Reverse Construction Technology of Large Cylindrical Structures

在钢铁冶炼水处理工程建设中,大型圆筒形钢筋混凝土旋流池工程施工难度大且工期长,针对不同地质条件需要采取不同施工技术措施。以某大型钢铁冶炼工程地下钢筋混凝土旋流池为例,在上层回填土中采用大开挖方式的顺作法施工,下层硬土中采用逆作法分层施工,通过开发和改进多种施工技术措施,有效加快施工进度并保证工程质量。

In the construction of iron and steel smelting water treatment project,the construction of large cylindrical reinforced concrete swirling pool project is difficult and its period is long. Different construction technical measures should be taken for different geological conditions. Taking underground reinforced concrete swirling pool of a large iron and steel smelting project as an example,in the upper backfill soil,the normal construction method of large excavation method is used in the construction,and the lower layer of hard soil is constructed by reverse construction method. Through the development and improvement of a variety of construction technical measures,the construction progress is speeded up and the quality of the project is guaranteed.
