[0002] A pontoon bridge is a device installed on the water surface. When the road encounters obstacles such as rivers, lakes and water networks, resulting in traffic interruption, the pontoon bridge can be used to solve the problem that personnel and vehicles cannot pass.

[0003] The patent with the publication number of CN201621345543.8 discloses a steel pontoon bridge, in which pontoons are arranged on the water surface, and pedals are arranged on the pontoons to form a continuous pontoon section, thus solving the problem of traffic passage of personnel on rivers, lakes and water networks.

[0026] Beneficial effects:

[0027] (1) The modular arch-shaped floating bridge of the present invention includes more than two floating bridge units. Connecting more than two floating bridge units in sequence to form an arch-shaped floating bridge can achieve modular installation between the floating bridge units. At the same time, the floating pontoons, supports, and bridge decks within each floating bridge unit can also be modularly assembled, which is convenient for on-site erection of the arch-shaped floating bridge and improves the erection efficiency.

[0028] In addition, the present invention is provided with the arch beam I and the arch beam II. The bridge hole formed below the arch beam I and the arch beam II can meet the navigation of ships.

[0029] (2) The left frame body and the right frame body of the present invention also respectively include a bottom support beam I, a bottom support beam II, a transverse support beam, and several inclined support beams to improve the support strength of the support.

[0030] (3) The third support beam and the fourth support beam of the present invention are located on a vertical plane and are symmetric with respect to the central plane II; the bottom support beam I and the bottom support beam II are symmetric with respect to the central plane II; that is, the intersection point of the bottom support beam I and the bottom support beam II and the intersection point of the third support beam and the fourth support beam are located on the same vertical line, which can improve the overall support stability.

[0031] (4) In the inclined support beam group II of the present invention, the number of inclined support beams is greater than that in the inclined support beam group I. Since the right side of the right support needs to be connected to the adjacent floating bridge unit, more inclined support beams are provided on the right side than on the left side to ensure the support strength of the bridge deck after connection.

[0032] (5) The preset fixing parts are arranged at intervals on the top mounting plate of the present invention, and the bridge deck can be directly mounted thereon, improving the installation efficiency at the floating bridge erection site.

[0033] (6) The length direction of the floating pontoon of the present invention is consistent with the width direction of the support; and the center line in the length direction of the floating pontoon is vertically opposite to the center line in the width direction of the support; ensuring the smoothness when passing on the floating bridge.

Four mounting bases 21 are distributed on the top of each floating pontoon 2 and are correspondingly connected to the bracket bases 321 on the bracket 3 one by one to realize the connection between the bracket 3 and the floating pontoon 2.

[0063] Working principle:

[0064] The modular arched floating bridge uses the floating bridge unit 1 for modular splicing, and each floating bridge unit is composed of three modules: a floating pontoon 2, a bracket 3, and a bridge deck 4, which is convenient for the on-site erection of the arched floating bridge and improves the erection efficiency;

[0065] The floating pontoons 2 at the bottom of the modular arched floating bridge are located on the water surface, and the buoyancy generated by the water makes the arched floating bridge above the water surface;

[0066] The bridge holes formed below the arched beam I 302 of the bracket 3 of the modular arched floating bridge and the arched beam II formed by splicing two floating bridge units can both realize the navigation of ships. At the same time, the setting of the arched beam has a certain supporting strength and can support the bridge deck under force;

[0067] The anti-slip bridge deck 4 at the top of the modular arched floating bridge enables the passage on the bridge.
