摘要
逆作法施工由于采取盖挖,土方开挖施工难度增大,效率降低,土方开挖对项目工期和成本影响都比较大,本文结合某大型逆作法项目,通过采取半逆作、盆式开挖、两层一挖等措施,大大减少了盖挖量,提高了土方开挖速度,降低了工程成本。
Reverse construction due to take cover digging, earth excavation construction difficulty increases, reduced efficiency, earth excavation impact on the project schedule and cost is relatively high, combined with a large reverse project, by taking a half basin excavation, two layers of a digging and other measures, greatly reducing the amount of cover up, improve the excavation speed, reduce the cost of the project.
