The utility model provide technical scheme be：A kind of Gravity harf structure on Muddy Bottoms soil matrix, its feature exist In, including：Silt soil strata, flexible pile, block ground mass bed, armoured concrete slab, hollow square, wharf shoulder, block stone rib body；Institute The soil layer of the top layer that silt soil strata is sea bed or the low bearing capacity that shallow-layer is covered is stated, the flexible pile is piled at sea bed and penetrates The silt soil strata, described piece of ground mass bed are the described silt soil strata after excavation of jackstone and flexible stake top, the reinforcing bar Concrete slab is installed on described piece of ground mass bed, and the hollow square is installed on the armoured concrete slab, the harbour chest Wall be cast-in-place concrete or it is prefabricated be installed on above the hollow square, described block of stone rib body jackstone in hollow square, it is hollow Square and wharf shoulder rear, the overall structure that each several part is formed.

Improvement to above-mentioned technical proposal：The flexible pile has multiple rows of, and transverse and longitudinal has certain distance, and the flexible pile is broken Stone mar, sand pile or major diameter substitution block stone mar.

Further improvement to above-mentioned technical proposal：The armoured concrete slab is that unitary solid or local are hollow, and compared with The bottom width of the hollow square is big.

Further improvement to above-mentioned technical proposal：Described piece of ground mass bed is backed down in the silt soil strata, flexible pile After digging foundation trench, jackstone is formed.

Further improvement to above-mentioned technical proposal：The hollow square is hollow concrete prefabricated block, above-mentioned sky In heart square and rear backfill block stone rib body.

Further improvement to above-mentioned technical proposal：The wharf shoulder is cast-in-place coagulation at the top of above-mentioned hollow square Soil or the prefabricated components installed, the bottom width of the wharf shoulder are bigger than the hollow square top width.

The utility model is had the advantage that and good effect compared with prior art：

The Gravity harf structure on Muddy Bottoms soil matrix that the utility model is provided, by the muck soil to low bearing capacity Layer sets flexible pile and carries out foundation stabilization, improves bearing capacity, arranges armoured concrete slab, hollow square, off-load on block ground mass bed The wharf shoulder of formula, reduces arranging block stone rib in bedding top and the active force of ground, hollow square and rear, wharf shoulder Body, forms overall Gravity harf structure, effectively reduces dock structure width, foundation stabilization width, to foundation bearing capacity Requirement, be easy to construction, low cost.
