Description
Technical Field
The utility model belongs to the technical field of, especially, relate to an old pier of mixed structure rebuilds structure.
Background
Some old wharfs which operate decades, wharfs with a mixed structure of high-pile beam-slab wharfs and gravity wharfs, the design and construction adopted specifications are versions before decades, the thickness of protective layers at the positions of wharf surface layers, the bottoms of longitudinal beams and transverse beams of the high-pile beam-slab wharfs is thinner, under the collision of various operation machines, the protective layers are often peeled off and leak steel bars, the wharf panel is damaged and cannot meet the operation requirements of modern vehicles, driven piles before decades have small effective pre-compression stress values of pile bodies, the probability of cracks appearing on the pile bodies is higher in the pile sinking construction stage, the technology is laggard, the pile lengths and the pile diameters are small, the bearing capacity cannot meet the transfer load of modern ships and goods, and in the operation process of decades, the mooring force, the system force, the adsorption force of oysters and the wave force of tide rise of the ships often cause the burst and crack of the concrete at the driven pile heads, The diameter of the steel bar is reduced due to the falling of the steel bar, the physical and mechanical properties of the steel bar are greatly reduced due to the chlorine ions in the seawater, and the pile foundation cannot bear the constant load of the bridge crane, the container and other operation stages, so that the high-pile beam-slab wharf is required to be reconstructed and expanded after being operated for a period of time.
And the gravity type wharf structure adopts plain concrete structure, its degree of depth reaches tens meters, and concrete is because of its material performance itself, and the sea water corrodes often can not lead to its intensity to reduce in decades, therefore in the transformation work of old pier, if adopt and demolish tens tons of to hundreds of tons of concrete squares, the manpower of consumption, mechanical cost and time cycle are very huge, and the concrete in the work progress drops to the sea water, lead to the sea water degree of depth to become shallow and lead to the construction boats and ships can't clear away the operation because of touching the bottom. The technical difficulty and cost of traditional mixed-structure old wharfs often lead to wharf transformation grounding.
Traditional high stake beam slab wharf and gravity type wharf's mixed structure wharf's transformation work often adopts a large amount of stones to throw in the soft soil foundation and fills, the surface course is reinforced concrete structure, often reach several tens of thousands to several hundred thousand cubes because of throwing the stone square volume that fills out needs, its cost is huge, and exist because of the soft soil foundation of below, the foundation bearing capacity is relatively weak, even the higher lump stone layer of bearing capacity is adopted to the top, newly-built wharf road surface reforms transform and accomplishes the back, great settlement just can appear after several years, lead to the unable operation of pier.
