The utility model provides a big load plate structure of single pile is at least including piling load, sleeper support, percentage table, jack, clamp plate, girder and benchmark roof beam, pile the load setting two sleeper supports upper end and with sleeper support zonulae occludens, sleeper support symmetry sets up in the benchmark roof beam outside, the girder setting just tightly connects with a heap load at heap load lower extreme, the girder is just supported in the jack setting under the girder, the percentage table symmetry sets up in the jack both sides, clamp plate zonulae occludens is at the jack lower surface and through steelframe and percentage table fixed connection, the setting of benchmark roof beam is on the percentage table right side and have support and percentage table to meet, this big load plate structure of single pile is simple, increases the participation service factor of soil, has reduced subsiding of composite foundation, has solved the not uniform settlement problem of building or structures effectively, can the perpendicular load of effectual transmission, increase substantially the foundation bearing capacity, improve between the stake soil nature can, the practicality is strong, be fit for using widely.
