混凝土导管

Underwater concrete of bored piles were poured by lifting conduit method, while overwater concrete pouring adopted drawing ball technique.

钻孔灌注桩水下混凝土采用提升导管法施工，水上混凝土灌注采用拔球的施工技术，介绍了施工注意事项及应对措施。

Take care that the tremie does not touch the rebar cage or is clogged.

浇筑首盘混凝土时，导管底部至孔底距离控制在35～40cm。

In the whole procedure of concrete casting it is essential that the tremie is for at least 1.5m, up to 5m, beneath the concrete surface to prevent the slurry runs into the tremie.

在整个砼浇筑时间内，导管口应埋入先前浇筑的混凝土内至少1.5m，防止泥浆冲入管内，但不得大于5m。

Cast the underwater concrete with a soccer ball; the volume of the first batch of concrete is to be calculated, ensuring that the depth of the tremie embedded in the concrete for at least 1m and can fill the apertures at the bottom.

采用砍球法浇筑水下混凝土，首盘混凝土需用量由计算确定，保证首批混凝土浇筑后导管埋入混凝土中的深度≮1m，并能填充导管底部间隙。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
