奥林匹克公园B27-2项目大体积混凝土浇筑溜筒应用研究

摘要

针对奥林匹克公园B27-2项目基础混凝土浇筑问题, 提出了一种大体积混凝土浇筑溜筒应用研究.通过搭设从地面到基础的溜筒, 让混凝土直接通过溜筒运输到基础的浇筑部位, 无需在现场使用多台泵车, 解决了场地狭窄的问题.该方法能有效提高狭窄场地混凝土的浇筑速度, 保证大体积混凝土的浇筑质量, 为今后同类工程提供了一种新的施工思路.%The application of slip cylinder for large volume concrete pouring is proposed, aiming to solve the problem of foundation concrete pouring in section B of Olympic Park B27-2 project.By setting up the slip cylinder from the ground to the foundation, the concrete is transported directly through the cylinder to the foundation. This method can avoid the use of multiple pumps, which is useful for narrow construction sites. It can effectively improve the pouring speed of concrete in narrow site and ensure the quality of large volume concrete pouring, which provides a new idea for similar projects in the future.
