The invention discloses a one-quarter cylinder on-site splicing method for lattice type steel sheet pile large cylinder main lattice sheet piles. According to the overall method, a full circle main lattice is divided into four one-quarter circular steel sheet pile assembly pieces which are respectively lifted, and therefore the requirements for the lifting distance and the lifting capacity of a crane ship are lowered; meanwhile, the on-site workload is greatly reduced; only the four one-quarter circular steel sheet pile assembly pieces need to be hung, and then four folding piles are spliced. By the utilization of the scheme, under the on-site conditions (namely high construction region limit, shallow water, poor geological conditions and high marine environmental requirements) that all is limited and under the execution conditions including construction period requirements, a lattice type steel sheet pile large cylinder can be accurately and stably lifted and sunken. |
