AI Technical Summary

Problems solved by technology

However, the structural assembly of traditional pontoon bridges is cumbersome and inconvenient to use. Even the combination of some pontoon bridge structures has no buffering effect. When the water flow is strong, the bridge body may be washed away directly, which is more dangerous to use.
In terms of manufacturing and installation, the current structural form of the pontoon system is relatively complicated, and most of them are constructed by on-site construction, which causes great damage to the surrounding environment
Moreover, the combination and disassembly of the traditional pontoon bridge is relatively complicated, which is not convenient for transportation
[0003]Most of the existing floating bridge systems are temporary and cannot be used for a long time, causing certain environmental protection and cost problems
For example: in order to facilitate the fixing of the pontoon bridge, the pontoon bridge is usually connected to the positioning piles inserted into the bottom of the lake. There is a buoyancy support part under the pontoon. The current buoyancy part is usually made of solid foam material, and the pontoon is installed on the solid foam material through bolts. Due to the low strength of the foam material, the installation part is easy to loosen after a period of time
At the same time, the foam material has certain pollution to the water body.
[0004] It can be seen that the existing pontoon bridges have many problems such as insufficient environmental protection, troublesome assembly, poor stability and inconvenient disassembly and assembly, which makes the overall performance of the pontoon bridge poor and low in practicability

Embodiment 1

[0047] Please refer to figure 1 with figure 2, Embodiment 1 of the present invention is:

[0048] An assembled detachable pontoon such as figure 1 with figure 2 As shown, it includes a bridge deck 1 , a support 2 , a fixed bracket 3 , an airbag floating body 4 and a counterweight 5 . Wherein, the bottom of the bridge deck 1 is provided with a plurality of supports 2 along the extending direction of the bridge deck 1, the supports 2 are fixedly connected with the bottom of the bridge deck 1, and the end of each support 2 away from the bridge deck 1 corresponds to a fixed bracket 3 Fixedly connected, the airbag floating body 4 is fixed in the fixed bracket 3, and the other end of the fixed bracket 3 is fixedly connected with the counterweight 5. Specifically, the counterweight 5 can use a concrete counterweight 5 . The supporting member 2, the airbag floating body 4 and the counterweight 5 are arranged sequentially from top to bottom to form a laminated structure.

Abstract

The invention discloses an assembly type detachable floating bridge. The assembly type detachable floating bridge comprises a bridge surface, supporting pieces, fixing supports, air bag floating bodies and balancing weights. A plurality of supporting pieces are arranged below the bridge surface in the extending direction of the bridge surface, the supporting pieces are fixedly connected with the bottom of the bridge surface, the end, away from the bridge surface, of each supporting piece is fixedly connected with one fixing support correspondingly, the air bag floating bodies are fixed in the fixing supports, the other ends of the fixing supports are fixedly connected with the balancing weights, the supporting pieces, the air bag floating bodies and the balancing weights are sequentially arranged from top to bottom to form a stacked structure. Compared with the design of supporting structures such as positioning piles, the bridge surface supporting structure design which mainly comprises the supporting pieces, the air bag floating bodies and the balancing weights has the advantages that the influence of unreasonable factors such as deflection and abrasion of the supporting structures on the stability of the floating bridge can be eliminated, the environment cannot be polluted by adopting the air bag floating body design, the structure is simple, assembling is convenient, the comprehensive performance is good, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an assembled detachable floating bridge. Background technique [0002] A pontoon bridge refers to a bridge that uses pontoons or airbags instead of piers to float on the water. There are two main structural forms of traditional pontoon bridges: one is the form in which girders are erected on ships or pontoons and then paved with bridge decks; the other is the form in which ships are connected end to end or the hulls are closely arranged in belts. However, the structural assembly of traditional pontoon bridges is cumbersome and inconvenient to use. Even the combination of some pontoon bridge structures has no cushioning effect. When the water flow is strong, the bridge body may be directly washed away, which is more dangerous to use. In terms of manufacturing and installation, the structure of the current pontoon bridge system is relatively complicated, and most ...
