Abstract

The utility model relates to a cross-sea floating bridge, in particular to a multifunctional permanent floating bridge. The bridge has the advantages of high tide-proof and anti-inclination and the left-right floating of the bridge is prevented. The bridge comprises a floating tank of the bridge body, a steel-structure undercourse, a deck, a floating tank, a leveling device, pulleys, wires, sinkers and a wave impact-reduction device. The investment cost and the technical difficulty, which can not be simultaneously reduced by conventional cross-sea hanging bridges and floating bridges, can be solved by the simple-structure and practical technology of the utility model. According to the utility model, the floating bridge is stabilized by connecting wires with seabed soil with the collaboration of pulleys and sinkers. Anti-inclination floating tanks are arranged at the two ends of the bridge to ensure the balance of the bridge. Two suspension wires connected with an anti-inclination sinker are respectively connected with the steel-structure supports at the two ends of the bridge. Whether the pulleys are stopped or not is controlled by the magnetic effect of the anti-inclination leveling device at the intermediate of the bridge. The sinkers used for preventing the left-right and up-down floating of the bridge are respectively connected with two fixed mixing parts at the seabed via the pulleys by two suspension wires.

The specific embodiment:

Arrive shown in Figure 7 as Fig. 1; this sea-crossing float bridge specifically comprises: by permanent buoyancy tank one by one contact (1); bridge floor is floated; steel structure support is equipped with in the pontoon bridge both sides; be separately installed with on the support and subtract sea beat boundary belt (26) more than two; (27); the buoyancy tank (3) that anti-bridge floor tilts also is installed in addition; anti-inclination sash weight (5); messenger wire; anti-pontoon bridge is fast with wave lifting gear and anti-body of a bridge tilting gearing such as Figure of description (5); the enough big composite soil of piece is arranged in the seabed; there is an end of a steel wire to connect composite soil; pulley below the process steel work; magnetic is installed makes its urgent rising that is subjected to seawater will formulate pulley automatically; make its body of a bridge can be with wave fast lifting; this is novel to prevent the device such as the Figure of description (4) that float about body of a bridge level in addition; this installs it and is constructed as follows: the composite soil that connects the seabed with an end of a steel wire; the other end connects a sash weight; also link to each other in the middle of this steel wire in addition with pulley; last this root steel wire links to each other with the composite soil in opposite side seabed, and the bright spot of this pontoon bridge maximum is with the steady body of a bridge of messenger wire.

Introduce method of attachment and its role of each parts of this sea-crossing float bridge below respectively:

At first introduce body of a bridge buoyancy aid, shown in figure two: this body of a bridge buoyancy aid is assembled by several permanent buoyancy tanks (1), each buoyancy tank (1) can be extracted out separately, to make things convenient for I﹠M, each buoyancy tank flat raft is formed a firm buoyancy tank plane body of a bridge, at this steel work bed course support (8) is installed above the plane, bridge floor (10) is installed on this support;

Introduce anti-body of a bridge left and right horizontal floating installation below, as Fig. 4, when the body of a bridge floats to a side with the wave level, the sash weight (17) that links to each other with steel wire (13) can rise under pulley drives, being installed in a certain locational survey horizontal device of the body of a bridge is that level gauge (the level gauge device does not show in the drawings) can be measured automatically, when its horizontal drift just can be by stuck automatically to a certain degree, this stuck stop technology can adopt par fish and water paperback to put with magnetic stop association and watch operating technology, certainly this stuck stop technology can also adopt other technology, as long as reaching automatic stuck stop just goes, on the contrary when wave when opposite aspect floats, sash weight (17) can descend under the effect of gravity automatically, position when getting back to original body of a bridge balance, it just effectively prevents the problem that the left and right horizontal of the body of a bridge is floated like this.

Introducing anti-pontoon bridge then fluctuates and anti-body of a bridge tilting gearing fast, as shown in Figure 5, its formation is to be connected on the composite soil in seabed with (22) through pulley (20) by a messenger wire (23) again, when a side of the body of a bridge during because of certain reason run-off the straight, when body of a bridge gradient reaches a certain amplitude, being installed in a certain locational survey horizontal device of the body of a bridge is that level gauge (the level gauge device does not show in the drawings) can be measured automatically, at this moment the anti-pontoon bridge that is positioned at body of a bridge opposite side fluctuates fast and the pulley (22) of anti-body of a bridge tilting gearing can be stuck automatically under the magnetic control of (the magnetic device does not show in the drawings), be that pulley is lockable, the body of a bridge can only tilt to limited gradient like this, like this after the body of a bridge is replied balance, pulley is unlocked again, guarantees that with this body of a bridge can arbitrarily not tilt; In addition should anti-pontoon bridge fluctuate fast and anti-body of a bridge tilting gearing (Fig. 5) prevents that in addition the body of a bridge is with wave this function that fluctuates fast, when roam fluctuates too fast, the automatic stuck pulley of this device meeting, this stuck stop technology is the same, fluctuates fast to influence the stability of the body of a bridge to prevent the body of a bridge;

Introduce anti-inclination sash weight (5) once more, as figure (6), its mounting method is to make it be suspended on the both sides that body of a bridge cross section is the body of a bridge respectively with two steel wires, makes its balance that keeps the body of a bridge under the effect of gravity, to prevent its inclination.

Then introduce anti-inclination buoyancy tank (3), as scheming (6): this device is installed on the both sides that body of a bridge cross section is the body of a bridge equally, all there is anti-inclination buoyancy tank body of a bridge both sides, this buoyancy tank links to each other with the both sides of the steel work bed course support (8) of the body of a bridge by steel structure support (7), water is placed by each buoyancy tank lower floor, the hollow water of promptly declining in upper strata, when under the effect of the body of a bridge at gravity during to lopsidedness, the anti-inclination buoyancy tank of this side can be to sinking, but because of this water tank upper strata is hollow, it can upwards float under buoyancy function; Simultaneously, because the body of a bridge one direction finding is sunk, the anti-inclination buoyancy tank of body of a bridge opposite side can upwards float even be unsettled, and this moment, the buoyancy tank buoyancy of water descended, and the body of a bridge can prevent the bridge floor tilting action thereby play in the effect of gravity to decline.

Introduce at last and subtract sea beat device (28), as Fig. 7: originally subtract the both sides that the sea beat device is installed in steel work bed course support, device such more than two is installed as required, these devices one in front and one in back, when this device of sea beat, seawater just flows through from numerous water channel holes of this device, so successively through behind several such devices, the impact force of wave is just dissolved, thereby strengthens body of a bridge stationarity.
