Abstract

The utility model discloses a pontoon bridge capable of floating on the water surface. The floating pontoon bridge adopts the technical proposal that piers which can float on the water surface and can support the required weight of the bridge are formed by combining a large amount of light materials; a complete pontoon bridge is formed by combining the piers with the bridge; the floating solid piers made from the large amount of light materials are arranged in water; and the weights of the bridge as well as vehicles and passersby on the bridge are supported by enough buoyancy produced by the piers in the water. The floating pontoon bridge has the advantages of novel structure, simple manufacture, low cost, easy construction, no fear to floods, resistance to stormy waves and convenient maintenance.

Description

A kind of floatation type pontoon bridge waterborne

Technical field

The utility model relates to aquatic building, particularly can be in any water surface building, can be used for the pontoon bridge waterborne of pedestrian or vehicle pass-through.

Background technology

It is very inconvenient that a large amount of rivers bring for the interchange of riverine two sides, by ship cross send promptly bother and speed too slow.For solving the two sides traffic difficulties, need to drop into substantial contribution and build bridge.The common pier bridge construction of building is often constructed difficultly, and the cost cost is higher, and is particularly too dark at river, and bridge is built in the place of river bed complicated geology, and then construction is very difficult, and cost is then very expensive.Some local hull that adopts is made provisional transfer bridge as bridge pier, but such transfer bridge can not use for a long time because whatsoever all unavoidable long-living time of the hull of sample use and breakage occurs and leak, make that whole bridge occurs tilting, distortion and can't using.

Summary of the invention:

The purpose of this utility model just provides a kind of simple, with low cost, as to be easy to construct, can be suitable for various needs floatation type pontoon bridge waterborne of making.

Floatation type of the present utility model pontoon bridge waterborne, relatively simple for structure, combine by vehicle, pedestrian's the body of a bridge and the buoyancy aid bridge pier of body of a bridge below exactly.All buoyancy aid bridge piers are fixed in the below of the body of a bridge.

Floatation type of the present utility model pontoon bridge waterborne is to adopt the floatability lightweight object to manufacture the floatation type solid pier, uses buoyancy of water and supports the whole weight that goes up carrying object on the pontoon bridge; According to different ambient conditions, the body of a bridge of carrying object can directly be built on the buoyancy aid that fuses, and also can be fixed on the bridge pier of separation by crane span structure.Whole pontoon bridge manufacturing is simple, of many uses, plasticity is strong, has following characteristics:

1, the weight of whole pontoon bridge and institute's carrying object is to use buoyancy of water by floating bridge pier to support, and floats in the water surface, does not contact with the bottom, so do not fear the depth of water, is not subjected to water-bed ambient influnence, thereby effectively solves the not good and constructional difficulties that causes of deep water or water-bed environment.

2, whole pontoon bridge floats on the water surface, fluctuates with SEA LEVEL VARIATION, so be not afraid of the influence of SEA LEVEL VARIATION, more useful is not fear flood, does not hinder current.

3, be to combine in order to the buoyancy aid bridge pier that produces buoyancy, so can not produce the phenomenon that the pontoon bridge that is linked to be as common hull sinks because of hull damage, water inlet by the entity material.As long as the body of a bridge is of a tightly knit structure, just do not have the generation of inclination, the heavy accident of collapsing.

4, the buoyancy aid bridge pier of whole pontoon bridge is by a large amount of combining after surface protection processing is handled as the polystyrene type lightweight object; make the material of these buoyancy aid bridge piers and manufacture craft do not need to require too high, so the construction cost of its underwater portion of on-water bridge of this pattern will reduce greatly.

5, whole pontoon bridge and the object that carried all are to float on the water surface, can arbitrarily its position be moved at any time according to environment or changes in demand.

6, whole pontoon bridge and the object that carried all are to float on the water surface, thus can be as required, by changing way such as buoyancy size the distance of its bridge floor and the water surface is moved up and down.

Description of drawings

Fig. 1 is an overall structure schematic diagram of the present utility model;

Fig. 2, Fig. 3 are overall structure lateral view of the present utility model;

The specific embodiment

Core concept of the present invention is: the entity of a large amount of lightweights is processed integrated the back as the whole bridge of carrying and by the vehicle on it and the floatation type solid pier of pedestrian's weight, such floatation type solid pier and body of a bridge combination back are formed the on-water bridge that can float in the water surface.Wherein, the floatation type solid pier is to place water, by the enough buoyancy of this floatation type solid pier combination results in water, thereby supports all wt of whole bridge.

The present invention is described in detail below in conjunction with accompanying drawing.

With reference to Fig. 1, Fig. 2, be the schematic diagram and the lateral view of floatation type on-water bridge basic structure of the present invention;

As shown in Figure 1 and Figure 2, this on-water bridge comprises the split floatation type bridge pier " 2 " of the combined type body of a bridge " 1 " and its below.It is characterized in that the body of a bridge " 1 " is directly to be fixed on above the bridge pier " 2 ".Bridge pier " 2 " places the water surface, and the body of a bridge " 1 " is owing to the support that bridge pier " 2 " have been arranged is floated on the water surface, thereby plays the effect of on-water bridge.

With reference to Fig. 3, be the structure side view of the floatation type pontoon bridge waterborne of disjunctor floatation type bridge pier of the present invention;

As shown in Figure 3, this disjunctor floatation type bridge pier " 2 " is to be integrated through processing by a large amount of modular lightweight object to fuse, and is not having under the situation in navigation channel the be more convenient for construction construction of the body of a bridge of this structure.

More than explanation just is used for helping to understand characteristics of the present utility model and core concept thereof, for one of ordinary skill in the art, according to thought of the present utility model, part in specific embodiments and applications all can change, in sum, this description should not be construed as restriction of the present utility model.

Claims

1, a kind of floatation type pontoon bridge waterborne comprises the combined type body of a bridge (1) and buoyancy aid bridge pier (2), it is characterized in that: the body of a bridge (1) below is provided with the buoyancy aid bridge pier of arranging along bridge floor (2).

2, floatation type according to claim 1 pontoon bridge waterborne is characterized in that: the body of a bridge (1) closely is fixed on the buoyancy aid bridge pier (2).
