Description

Technical Field

[0001] The utility model relates to the technical field of floating bridges, in particular to an assembled floating bridge for both water and land use. Background Art

[0002] As a prefabricated equipment, the floating bridge has the characteristics of prefabricated design, industrialized production, and prefabricated construction. It has the advantages of improving the efficiency of bridge construction, and will not cause pollution to the waters where it is located during the production and construction process, which is green and environmentally friendly.

[0003] However, as traditional floating bridges have high requirements for water level and underwater terrain, the water level in the area where the floating bridge is used cannot change too much, and the floating bridge cannot run aground after the water level drops. If the above situation occurs, the structural stability of the floating bridge will be affected. If the water level rises too much, it may exceed the load capacity of the floating bridge, resulting in damage to the structural stability. This may cause partial or overall damage to the floating bridge. Rising water levels may cause the channel connecting the floating bridge and the two banks to be submerged, making it impossible for the floating bridge to connect the two banks normally, affecting the passage of pedestrians and vehicles. Dropping water levels may also cause the floating bridge to run aground, hindering the smooth flow of traffic, which will seriously affect the use of the floating bridge.

[0004] Therefore, in order to solve this problem, a prefabricated water-land dual-purpose floating bridge which can be used normally with or without water is provided. Utility Model Content

[0005] The purpose of the utility model is to provide an assembled floating bridge for both water and land use, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] An assembled floating bridge for both water and land use, comprising a bridge body, a bank-connecting gangway, and an anchoring system for limiting the bridge body to the river bank, wherein the bridge body comprises a plurality of floating bridge units connected as one by a pin shaft, the floating bridge unit comprises a plurality of pontoons, and guardrails arranged on both sides of the pontoons, wherein the plurality of pontoons are connected by a pin shaft and a bridge deck is formed on the top surfaces of the plurality of pontoons;

[0008] The connecting end of the bank-connecting gangplank is rotatably connected to the connecting ear of one end of the bridge body connected to the river bank through a second pin shaft, and the other end of the bank-connecting gangplank is fixed to the bank;

[0009] The anchoring system includes four positioning piles, which respectively penetrate into four limiting steel sleeves at the front and rear ends of the bridge body and float up and down in coordination with the floating of the bridge body. The four positioning piles are respectively provided with limiting platforms for supporting the bottom surface of the bridge body, and the bottom surface of the bridge body is supported by the limiting platforms.

[0010] Furthermore, the pontoon is a sealed box body assembled from an external waterproof plate and an internal supporting keel. A plurality of reinforcing rib plates are provided inside the pontoon to cooperate with the internal supporting keel for stable support. One pontoon can be assembled from eight standard boxes by means of upper and lower pin connections. The internal supporting keel and the reinforcing rib plates cooperate to support the pontoon and maintain the anti-deformation effect of the pontoon after bearing weight.

[0011] Furthermore, a plurality of the pontoons are assembled by splicing in a straight line or a curve through a first pin shaft, and the pontoons are arranged to be located on the water surface in a straight line and horizontally or in an arc shape according to the water level of the river.

[0012] Furthermore, corresponding plug-in connecting ear plates are respectively provided at the connection points of the front end and the rear end of the pontoon. After the connecting ear plates are docked, the first pin shaft penetrates the connecting ear plates and cooperates with the connecting ear plates to limit rotation. The connecting ear plates are used to cooperate with the first pin shaft to rotationally connect the two pontoons. When the pontoon is affected by the rise or fall of the water level, a limiting angle of the rotational connection is provided for the floating of the pontoon.

[0013] Furthermore, the upper surface of the pontoon forms a bridge deck through the laying of steel beams or purlins.

[0014] Furthermore, the front and rear ends of the bridge body are respectively provided with extension trusses through pontoons, and the limiting steel sleeves are fixed on the outside of the extension trusses. The extension trusses support the limiting steel sleeves and limit the rotation angle of the positioning piles in coordination with the shore gangway through the limiting steel sleeves.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The assembled dual-purpose floating bridge for water and land is floated up and down by the rotational connection between the positioning piles and the limiting steel casings on the shore gangplanks at both ends, and the bridge body keeps a horizontal position. When in use, since a limiting platform is provided on the positioning piles, the elevation of the limiting platform must be able to meet the minimum working elevation that the floating bridge will not run aground and will not cause a too large height difference with the shore road surface. When the elevation of the pontoon connected to the limiting steel casing drops to a certain elevation, the limiting platform supports and limits the descent of the pontoon, so that when the water level continues to drop, the bridge body composed of the pontoon will not move downward. When the water level is lower than the bottom elevation of the pontoon, the bridge body becomes an ordinary land bridge, thus achieving the purpose of the floating bridge being dual-purpose for water and land.

[0017] Since the bridge body is connected to several pontoons through the first pin shaft to form the whole bridge body, the whole floating bridge can be disassembled for maintenance or moved to other places where it is needed according to the needs, achieving the effects of detachable reuse, energy saving and emission reduction, and green environmental protection.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-7 , the utility model provides a technical solution:

[0029] An assembled floating bridge for both water and land use, comprising a bridge body 1, a bank-connecting gangway 2, and an anchoring system 3 for limiting the bridge body 1 to the river bank, wherein the bridge body 1 comprises a plurality of floating bridge units 15 connected as a whole by pins, the floating bridge unit 15 comprises a pontoon 4, and guardrails 5 arranged on both sides of the pontoon 4, wherein the plurality of pontoons 4 are connected by pins and a bridge deck 7 is formed on the top surfaces of the plurality of pontoons 4;

[0030] The connecting end of the bank-connecting gangplank 2 is rotatably connected to the connecting ear 16 of one end of the bridge body 1 connected to the river bank through the second pin shaft 8, and the other end of the bank-connecting gangplank 2 is fixed to the bank;

[0031] The anchoring system 3 includes four positioning piles 9, which respectively penetrate four limiting steel sleeves 14 at the front and rear ends of the bridge body 1 and cooperate with the up and down floating of the bridge body 1. The four positioning piles 9 are respectively provided with limiting platforms 10 for supporting the bottom surface of the bridge body 1, and the bottom surface of the bridge body 1 is supported by the limiting platforms 10 to form a floating bridge unit.

[0032] The pontoon 4 is a sealed box body assembled by an external waterproof plate and an internal supporting keel. A plurality of reinforcing rib plates 11 are arranged inside the pontoon 4 to cooperate with the internal supporting keel for stable support. One pontoon 4 can be assembled from eight standard boxes by means of upper and lower pin connections. The internal supporting keel and the reinforcing rib plates 11 cooperate to support the pontoon 4 and maintain the anti-deformation effect of the pontoon 4 after bearing weight.

[0033] A plurality of pontoons 4 are assembled by splicing in a straight line or a curve through the first pin shaft 6. The pontoons 4 are arranged to be located on the water surface in a straight line and horizontally or in an arc shape according to the water level of the river.

[0034] The connection between the front end and the rear end of the pontoon 4 is respectively provided with corresponding plug-in connecting ear plates 12. After the connecting ear plates 12 are docked, the first pin shaft 6 penetrates the connecting ear plates 12 and cooperates with the connecting ear plates 12 to limit rotation. The connecting ear plates are used to cooperate with the first pin shaft 6 to rotationally connect the two pontoons 4. When the pontoon 4 is affected by the rise or fall of the water level, the limiting angle of the rotation connection is provided for the floating of the pontoon 4.

[0035] The upper surface of the pontoon 4 forms a bridge deck 7 through the laying of steel beams or purlins.

[0036] The front and rear ends of the bridge body 1 are respectively provided with extension trusses 13 through the pontoons 4, and the limiting steel sleeves 14 are fixed on the outside of the extension trusses 13. The extension trusses 13 support the limiting steel sleeves 14 and limit the angle of rotation of the positioning piles 9 in cooperation with the shore gangway 2 through the limiting steel sleeves.

[0037] In the assembled dual-purpose floating bridge for water and land, the bridge body 1 floats up and down through the rotational connection between the positioning piles 9 on the shore gangplanks 2 at both ends and the limiting steel casings, and keeps the horizontal position motionless. When in use, since the limiting platform 10 is provided on the positioning piles 9, the elevation of the limiting platform 10 must be able to meet the minimum working elevation that the floating bridge will not run aground and will not cause a too large height difference with the shore road surface. When the elevation of the pontoon 4 connected to the limiting steel casing drops to a certain elevation, the limiting platform 10 supports and limits the descent of the pontoon 4, so that when the water level continues to drop, the bridge body 1 composed of the pontoon 4 will not move downward. When the water level is lower than the bottom elevation of the pontoon 4, the bridge body 1 becomes an ordinary land bridge, achieving the purpose of the floating bridge for water and land.

[0038] Since the bridge body 1 is connected to several pontoons 4 through the first pin shaft 6 to form the whole bridge body 1, the whole floating bridge can be disassembled for maintenance or moved to other places for use according to the needs of maintenance, thus achieving the effects of detachable reuse, energy saving and emission reduction, and green environmental protection.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
