Aid-sedimentation construction method for open caisson engineering in dense round gravel layer or gravel layer
The invention discloses an aid-sedimentation construction method for open caisson engineering in a dense round gravel layer or a gravel layer, which is mainly used for solving the construction problem encountered very easily in the prior art that an open caisson sinks slowly and even does not sink in open caisson construction under the geological condition of the dense round gravel layer or the gravel layer. The aid-sedimentation construction method comprises the following steps: rotationally cutting soil masses in the range of cutting edges by rotary spraying of high-pressure rotary spraying water so as to reduce the percentage of the hard round gravel layer and the frictional resistance of the soil masses and cause the open caisson to sink by own gravity, determining the depth, radius and spacing which are needed by rotary spraying according to L1 and X% after sequentially calculating the critical frictional resistance, the area of round gravels scattered by the rotary spraying water on the peripheral wall sides of the open caisson, the depth L1 of the soil piercing part of the open caisson above the cutting edges and the area proportion X% of the round gravel layer improved at the cutting edges, then selecting an appropriate high-pressure jet grouting pile machine for scattering the soil masses, and cutting earth in the open caisson so as to cause the open caisson to sink by own gravity. By adopting the technical scheme, the aid-sedimentation construction method achieves the purpose of causing the open caisson to easily sink.
