Abstract

The utility model relates to a sea floating bridge which is characterized by being formed by a bridge floor assembly, floater cabins, floaters, bridge floating piers, sleeper beams, floater cabin support, gravity bridge piers, balance weight towing cables and balance weight hammers. The bridge floor assembly is arranged on the sleeper beams, the bridge floating piers are arranged under the sleeper piers, the bridge floating piers are fixed to the floater cabins through the floater cabin supports, the gravity bridge piers are connected under the floater cabin supports, the floater cabin supports are connected with the balance weight hammers through the balance weight towing cables, the floaters are arranged in the floater cabins, the sleeper beams are arranged on the bridge floating piers in a cross mode, and the bridge floor assembly is arranged on the sleeper beams in a sleeping mode. The sea floating bridge can be widely applied to highway bridges, railway bridges, highway and railway bridges, bridge tower suspension bridges and arch sling bridges. The sea floating bridge can be also used for building sea docks, sea land, sea airports and other sea and water-based facilities. The sea floating bridge has the advantages of being reasonable in design, convenient to construct, capable of achieving factory manufacturing and in-site construction, capable of reducing construction cost, safe and reliable.

Description

Marine pontoon bridge

Technical field

The utility model belongs to bridge design technology field, relates to a kind of marine pontoon bridge.

Background technology

At present, domestic relevant bridge design in the prior art, mainly contains beam bridge, slab bridge, arch bridge, steel structural bridge, suspension bridge, combined system birdge as cable stayed bridge and suspension bridge, pontoon bridge etc.Above-mentioned various beam bridge, slab bridge, arch bridge, its crossbeam of steel structural bridge and bridge floor mainly with simply supported beam mechanics form land on the sleeper beam of bridge pier, for strengthening stress and the amount of deflection of its rigidity, minimizing beam, certainly will to add the structure of crossbeam, bridge self static load is strengthened, also make bridge pier load increase the weight of, bridge pier certainly will want overstriking to strengthen, and increases construction cost and difficulty of construction.Suspension bridge and combined system birdge need to be built very high bridge tower, and its basis, bridge pier engineering cost are high, and difficulty of construction is large.Pontoon bridge is mainly used in inland river now, and does not also apply at present at sea, and the fatal shortcoming that current pontoon bridge exists is that bridge floor fluctuates along with the fluctuation of the water surface.

Summary of the invention

The utility model has overcome the defect of above-mentioned existence, object be for bridge construction provides one can factory process, site operation economical and practical, build little, the safe and reliable marine pontoon bridge of difficulty.

The marine pontoon bridge content Description of the utility model:

The marine pontoon bridge of the utility model, it is characterized in that: be to be formed by bridge floor assembly, float storehouse, float, the floating pier of bridge, sleeper beam, float bin bracket, gravity bridge pier, counterweight guy rope and counter weight, bridge floor assembly is arranged on sleeper beam, below sleeper beam, be provided with the floating pier of bridge, the floating pier of bridge is fixed on float storehouse by float bin bracket, at float bin bracket second line of a couplet gravity bridge pier, float bin bracket is connected with counter weight by counterweight guy rope, in float storehouse, be provided with float, on the floating pier of bridge, cross-arm is provided with sleeper beam, and bridge floor assembly pillow drops on sleeper beam.

The marine pontoon bridge of the utility model, can be widely applicable for road bridge, railway bridge, highway rail bridge, bridge tower suspension bridge and hunchbacked cable-suspended bridge, application the utility model also can be built sea harbour, marine land, seadrome and other marine and facility waterborne, has reasonable in design, easy construction, can realize factory process, site operation, minimizing cost, safe and reliable feature.

In figure: the 1st, bridge floor assembly, the 2nd, float storehouse, the 3rd, float, the 4th, bridge floats pier, the 5th, sleeper beam, the 6th, float bin bracket, the 7th, gravity bridge pier, the 8th, counterweight guy rope, the 9th, counter weight, A are that the water surface, B are sea bed faces.

Detailed description of the invention

The marine pontoon bridge of the utility model is achieved in that below in conjunction with accompanying drawing and illustrates.

See Fig. 1, the marine pontoon bridge of the utility model, be by: bridge floor assembly 1, float storehouse 2, float 3, the floating pier 4 of bridge, sleeper beam 5, float bin bracket 6, gravity bridge pier 7, counterweight guy rope 8 and counter weight 9 form.

Bridge floor assembly 1 is arranged on sleeper beam 5, is provided with the floating pier 4 of bridge below sleeper beam 5, and the floating pier 4 of bridge is fixed on float storehouse 2 by float bin bracket 6, is provided with float 3 in float storehouse 2.Upwards floating for preventing it, at float bin bracket 6 second line of a couplet gravity bridge piers 7, float bin bracket 6 is connected with counter weight 9 by counterweight guy rope 8.

The buoyancy that designing requirement float storehouse 2 produces will be far longer than the load of its top bridge floor assembly 1, is far smaller than again the gravity of gravity bridge pier 7 simultaneously.In the time that buoyancy is not enough, can in float storehouse 2, install according to setting buoyancy size the float 3 of sufficient amount additional.

On the floating pier 4 of bridge, cross-arm is provided with sleeper beam 5, and bridge floor assembly 1 pillow drops on sleeper beam 5.For anti-bridge floor downwarp, can add and put float storehouse 2 in the bridge floor bottom of bridge floor assembly 1, its buoyancy size and number, depending on the amount of deflection of required rectification bridge floor.

The floating pier 4 of bridge also can arrange suspension cable bridge tower or hoist cable back of a bow frame above.

When enforcement, the float of pontoon bridge 3 and float storehouse 2 are placed in to minimum undersurface lower seat.So, float 3 is not just affected by water level fluctuation.Float is fixed on bridge pier, and the gravity of bridge pier will be far longer than the buoyancy in float and float storehouse, and float and float storehouse can only be fixed in setting height.The bridge floor assembly of bridge and sleeper beam land are on bridge pier.The buoyancy that the float of the marine pontoon bridge of the utility model and float storehouse produce, the gravity that produce much larger than the dynamic loading on bridge floor assembly, sleeper beam and bridge floor.Float and float storehouse will be stabilized in the height of setting like this, and can not produce the phenomenon that descends slowly and lightly.

The marine pontoon bridge of the utility model, bridge pier is buoyancy bridge pier, and can add and put float and float storehouse on bridge pier, to increase the buoyancy of bridge pier.Float and float storehouse are placed under the sea after ebb deeply, bridge pier self buoyancy is the buoyancy in float and float storehouse in addition, be greater than the total load that bridge floor acts on bridge pier, counterweight in addition below float and float storehouse, makes float and float storehouse firmly be fixed on the height of setting under sea.The utility model can be widely applicable for road bridge, railway bridge, highway rail bridge.Also be suitable for bridge crane Sarasota is set thereon.Have reasonable in designly, build difficulty little, can realize factory process, on-the-spot installation.Cost is low, has overcome that existing pontoon bridge rises and falls with the water surface and unsteady shortcoming.Safe and reliable, can realize modularization, modularization, standardization.Application the utility model also can be built sea harbour, marine land, seadrome and other marine and facility waterborne.
