Abstract

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.

Description

technical field [0001] The invention relates to the field of bridge engineering, in particular to a sinking aid construction method for caissons. Background technique [0002] At present, the sinking aid measures taken for caissons generally include: water jet method, thixotropic mud jacket, air curtain, etc. The above sinking aids are mostly implemented at the beginning of caissons, and are mostly used in caisson wells. Outside the wall, the purpose is to reduce the friction between the well wall and the external soil. [0003] For the problems of slow sinking and stagnation in the construction stage of caisson sinking, the above-mentioned traditional sinking-assisting measures are difficult to achieve a good sinking-aiding effect, and the implementation cost is too high and time-consuming, which brings great disadvantages to the normal progress of the project. influences. Contents of the invention [0004] The object of the present invention is to solve at least one of...
