Described counterfort is the grooved counterfort, and the cross section of counterfort is a undaform, and crest and trough are straight line.
Buoyancy tank is the board-like structure of steel bar concrete, and promptly side plate, front sheet, deck, base plate, longitudinal bulkhead, transverse bulkhead are the inner concrete plate that is provided with reinforcing bar.
On clamping plate or side plate, also be provided with the limbers, the independent tank body in the buoyancy tank respectively is provided with a limbers.In order to regulate buoyancy tank weight, can be provided with the limbers of water-in and water-out at the buoyancy tank sidewall.
The utility model can design the buoyancy tank principal dimensions as the case may be in the process of design; Hydrogeologic data and ambient conditions according to embankment or revetment position; And the end absolute altitude of the inboard determined crest level of actual instructions for use, interior backfill elevation and levee body; By different treatment of soft foundation modes, after global stability analysis calculates, confirm the height and the width of buoyancy tank.The length of buoyancy tank is then according to the actual needs of engineering construction project, and after longitudinal strength is adjusted, confirms.Generally be advisable to be no more than 100m, the deadweight of buoyancy tank generally is controlled in the 1500t.
The formation of buoyancy tank: in general: buoyancy tank is the board-like structure of steel bar concrete, each monomer in the buoyancy tank wherein, and promptly side plate, front sheet, deck, base plate, longitudinal bulkhead, transverse bulkhead are the inner concrete plate that is provided with reinforcing bar.After each plate spliced, at integral constructing skirtboard, toe board etc.Concrete seam through the scene pouring between the segmentation of each plate fuses.For giving full play to the mechanical property of structural meterials, reduce the steel consumption, can carry out reasonable arrangement of reinforcement according to the suffered load of different parts, confirm the inside and outside protective layer thickness of each member of buoyancy tank by life requirement.Wherein about the segmentation seam, in general the segmentation seam of buoyancy tank all is arranged in the bulkhead position, and planed joint and vertical joint are united two into one, and the segmentation reserving rib is connected at seaming position, behind the formwork, and cast-in-place chiltern concrete; The buoyancy tank that forms like this is the most firm.In the polycrystalline substance: the buoyancy tank bottom fuses with skirtboard and toe board, and the size of skirtboard and toe board and arrangement of reinforcement move with the stressing conditions of overturning or slip resistance analysis according to antiskid to be confirmed through calculating.
Flat section---the integral constructing method is built in building berth, dock or cofferdam in the buoyancy tank employing, can adopt floating method, slope gravity, lift-on/lift-off system or air bag launching, the transportation by driving location.
Flute profile counterfort structure: flute profile counterfort plane cross section is the symmetric form structure, is divided into a flat section by a flute profile width, and the segmentation seam is arranged in the middle part of wainscot.
The flute profile counterfort fuses through connecting base and buoyancy tank basis, and the top is provided with the Cast-in-place concrete top board.The compound action of soil pressure, water pressure, wind-force and wave force when the structural strength of flute profile counterfort can be born different tidal level.
The use of buoyancy tank: buoyancy tank adopts the transportation by driving location.Behind the water, when high-tide level, drag toward assigned address under the buoyancy tank with tugboat or power ship, the sinking of pouring water, and to doing the soft base enforcement associating loading precompressed that discharging consolidation is handled.
The pouring of the hoisting and locating of flute profile counterfort, the processing of vertical joint and connection base concrete can be carried out when pontoon deck surfaces.
The sand resource situation of the visual construction area of backfill of rear land-based area is selected for use, is most economical to adopt high-power cutter suction dredger from the marine site of offshore certain distance, in embankment or revetment, to implement reclamation by pumping filling.But the layering of reclamation by pumping filling piecemeal is carried out, and the interim separation levee of buoyancy tank also capable of using during as dredge fill carries out block construction, also can play floating displacement after the completion of local plot and use.Also can separation levee be built up the pipe network gallery newly made in the plot or the zone canal that drains off floodwaters, to obtain the overall economic efficiency of engineering construction.
This patent adopts the prefabricated reinforced concrete buoyancy tank to do the basis, has reduced the deadweight of agent structure material consumption amount and levee body, has improved resistance to overturning; Inject Ballast Water in the buoyancy tank, can quicken the discharging consolidation of soft base; Buoyancy tank communicates with outside water, can overcome uplift pressure, but vacant state transportation by driving location also can be played floating displacement at any time and installed.On the skirtboard of buoyancy tank below, be provided with vacuum absorption device.Behind the buoyancy tank location, empty G&W is discharged from vacuum absorption device, and the buoyancy tank basal surface is close on the soft basic unit face, and leveling automatically, increases vacuum adsorption force, and the antiskid that has effectively improved levee body moves and resistance to capsizing.Toe board before and after the buoyancy tank bottom has increased the levee body bottom width, reduces the pressure of levee body to the basis, increases the overturning or slip resistance analysis arm of force, has improved factor of safety against overturning.
The prefabricated assembled grooved counterfort of steel bar concrete belongs to lightweight structures, can bidirectional stress, have certain wave absorbing function again, and aesthetic in appearance, manufacturability is strong.Connect base through cast-in-situ reinforced concrete and just can fuse with the buoyancy tank basis,, high consistent for the settlement difference between each buoyancy tank to keep top mark then through the adjustment of Cast-in-place concrete substructure height.
After backfill or reclamation by pumping filling form land-based area in the dike, combine together, become gravity embankment and revetment, behind the fill block stone throwing bank protection of the outside, can make levee body more reliable and more stable with overall structure grooved counterfort formula revetment or embankment.
Shown in Fig. 5～6: below be a kind of whole step scheme summary about the utility model:
The scheme step comprises: (1) is preset plastic draining board 21 in the appointed area; (2) the control buoyancy tank sinks down into assigned address; And skirtboard is absorbed in the sand cushion 22; (3), sand cushion surperficial successively lay geotextiles 23 and packed rubble inverted filter 24 inboard at buoyancy tank; (4) on packed rubble inverted filter, dose barged-in fill 25 at last; (5) in the buoyancy tank outside, sand cushion surface once-paving geotextiles, slabstone bed course 26, placed rockfill bank protection 27, geotextiles, rubble inverted filter 29 and stone paving 30 are being laid successively in buoyancy tank inboard, the surperficial straight highway section road surface pavement 28 of barged-in fill, the surface tilt zone of barged-in fill in (6).
