Abstract
The present invention discloses an Archimedes bridge with a protecting shell, which comprises a tube body and a supporting structure, wherein a shell is arranged outside the tube body; a proper gap is arranged between the inner surface of the shell and the outer surface of the tube body; the shell is in flexible connection with the tube body via a plurality of elastic pieces; the shell can move within a certain range corresponding to the tube body; after the outer part of the tube body of an Archimedes bridge is provided with a protecting shell, when a dynamic load exists, the dynamic external load is firstly loaded on the shell, and the shell transfers the dynamic external load to the tube body via the elastic pieces; in the process of transferring the dynamic load, the elastic pieces release the dynamic load and partially absorb the dynamic load; especially, after a through hole is arranged on a casing, when the casing moves corresponding to the tube body under the function of the dynamic load, water between the casing and the tube body is extruded from the through hole on the casing; by now, the release and the absorption of the casing toward the dynamic load are more obvious; thus, the load transferred to a cable via the tube body becomes very weak so as to effectively protect the tube body and the cable consequently.
Description
Technical field
The present invention relates to a kind of tunnel that is suspended in the water, i.e. Archimedes bridge.
Background technology
Archimedes bridge is since 1880s proposes, be accepted already as a kind of new traffic notion, have many countries all to drop into huge fund research in the world, and obtained a large amount of scientific achievements, science fiction is then coming true gradually.But, since this traffic notion of Archimedes bridge to relate to the field extensive, need the problem that solves numerous, therefore, up to the present also do not build up the Archimedes bridge of a practicality in the world.Build Archimedes bridge and at first will solve many engineering mechanics problems, wherein how weakening non-permanent perturbed force is again one of key issue to the effect of bridge.The research in past all is designed to Archimedes bridge by integral body with relevant patent or is divided into the several sections nearly rigid bodies that are configured to by steel, cement or steel and cement mixing, the non-permanent hydrodynamic force that such underwater components is subjected to can be directly passed to fixed cable, thereby the stress condition very severe of cable, be easy to be destroyed, and and then the safety that threatens whole Archimedes bridge.
Summary of the invention
At the existing problem of the Archimedes bridge that has proposed, the purpose of this invention is to provide a kind of Archimedes bridge that has guard shield, the guard shield of this bridge can be alleviated dynamic load and absorb effectively, thereby the safety of bridge is protected.
For realizing purpose of the present invention, Archimedes bridge of the present invention comprises body and braced structures thereof, described body is outside equipped with a shell, leave appropriate gap between the inner surface of this shell and the outer surface of tube body, shell and body flexibly connect by the plurality of elastic part, and described shell body relatively is movable within the specific limits.
Further, the stiff case of described housing for making by metal or steel concrete, the shape of its inner surface and the profile of described body adapt.
Further, described surface of shell also is provided with some through holes.
Further, the through hole of described surface of shell is uniform along its length and circumferencial direction.
Further, described several be metal spring or rubber spring with the elastic component that shell and body flexibly connect.
Further, described several be air bag with the elastic component that shell and body flexibly connect.
Behind the body outer setting guard shield of Archimedes bridge; when dynamic load exists; dynamically external applied load at first is loaded on the shell; shell passes to body by elastic component again; elastic component will be alleviated dynamic load and partially absorb in the process of transmitted load; especially after on the housing through hole being set; when body moves relatively under the effect of shell at dynamic load; water between shell and the body is extruded by the through hole from housing; at this moment housing will be more remarkable to the alleviation and the absorption of dynamic load; like this, finally be delivered to very faint that load on the cable will become by body, thereby body and cable thereof are effectively protected.
Description of drawings
Fig. 1 is an Archimedes bridge section structure schematic diagram of the present invention;
Fig. 2 is Fig. 1 structure left view;
Fig. 3 is an A portion enlarged diagram among Fig. 1;
Fig. 4 is the 2nd kind of elastic component embodiment;
Fig. 5 is the 3rd kind of elastic component embodiment.
The specific embodiment
Fig. 1, Figure 2 shows that cable type braced structures Archimedes bridge, this bridge mainly is made up of shell 1, body 2, cable 4 and elastic component 7, cable 4 is anchored at body 2 on the water-bed pedestal 5, shell 1 is made of metal, be sleeved on body 2 outsides, flexibly connect and support by elastic component 7 between shell 1 and the body 2.Cable 4 passes the through hole of the setting on the shell 1, also is provided with the through hole 3 of common water 6 turnover simultaneously on the shell 1, and several through holes 3 distribute along the length and the circumferencial direction of shell 1.
In embodiment illustrated in fig. 31, elastic component 7 is an air bag, and several air bags are arranged between shell 1 and the body 2, and is down static, and air bag 7 makes shell 1 and body 2 keep its initial equilibrium conditions.
In embodiment illustrated in fig. 42, elastic component 7 is a rubber spring.In embodiment illustrated in fig. 53, elastic component 7 is a metal spring.The effect of two kinds of springs is identical with the effect of air bag among the embodiment 1 among embodiment 2 and the embodiment 3.
When wave or whirlpool occurring around the shell 1 in the water 6, there is the dynamic load of water generates at first to be applied on the shell 1, under the effect of this external force, shell 1 moves along the direction of external force.After shell 1 relative body 2 moves, shell 1 compressing its with body 2 between water, the water of being oppressed is discharged from the through hole 3 on the corresponding side shell 1, and the water of opposite side outside is inhaled between shell 1 and the body 2 in the quilt gap of strengthening from through hole 3.In the water in shell 1 its gap of compressing, the elastic component 7 that is positioned at homonymy is compressed simultaneously, and the elastic component of its relative side is then stretched.Along with a row one of water inhales and a pressure one of elastic component is drawn, the part on the shell 1 in the suffered power is passed on the body 2.Because in the transmittance process of the power of between shell 1 and body 2, carrying out, being accompanied by a row one suction of water and a pressure one of elastic component draws, played good damping action at this water, absorb and alleviated the energy of most dynamic load, add the damping action of elastic component, it is very little that the feasible power that is passed on the body 2 becomes, and it is just littler to remake the power of using on the cable 4 by body 2, deficiency so that cable destroyed, thereby the safety of whole pontic is protected.
Increase the quantity of elastic component 7, shell 1 also can not be provided with through hole, at this moment still can reach same effect.
Adjust the aperture of through hole 3 on the shell 1, the distribution density of each one, can regulate the direction and the flow thereof of current targetedly, thereby reach control and adjust the damping effect of 1 pair of dynamic load of shell and shell 1 transmits purpose from the direction of power to body 2.
