Sinking assisting construction method of open caisson
The invention discloses a sinking assisting construction method of an open caisson. The friction force between the well wall of the open caisson and the soil body in the open caisson is reduced by digging a partition groove of an annular structure, the problems of slow sinking and even stagnation can be effectively solved in cooperation with graded balance weight, and the construction efficiency is improved; and meanwhile, a cofferdam on the periphery of the open caisson effectively prevents slurry in the partition groove from flowing out, so that the situation that the partition groove collapses is prevented, uneven ground settlement caused by water and soil loss is avoided, and the safety of the construction process is improved.
本发明公开了一种沉井的助沉施工方法，通过挖设环状结构的隔槽，使沉井井壁与其内部土体之间的摩擦力得以降低，配合分级配重，能够有效解决下沉缓慢乃至停滞的问题，加快施工效率，同时，沉井外周的围堰有效阻止了隔槽内泥浆的外流，从而防止了隔槽塌陷的状况发生，避免了因水土流失导致地面不均匀沉降，提高了施工过程的安全性。
