Elevating bicycle bridge and its application method

The present invention relates to a bicycle bridge construction method, and more particularly to a bicycle bridge built in the high beach and its application method.

As modern people pay more and more attention to environmental protection and health awareness, it is increasingly common to replace bicycles with bicycles or even bicycles as leisure activities. Correspondingly, the government is also committed to the remediation of green areas on both sides of the river and the construction of bicycle lanes, which will provide the public with a safe and comfortable bicycle riding environment. Therefore, bicycle lanes connected in series have been built on the high beaches on both sides of the rivers for bicycle users.

However, in terms of the existing bicycle lane design, it is more common to integrate the general bridge with the automobile and motorcycle, and it is rare to have a bicycle bridge built for bicycles. Because the general bridges passing through the locomotives are over-trended, the height is higher than the river surface, or even higher than the high beaches on both sides of the river. Therefore, a slope-type bicycle traction track or a rotary bicycle traction path must be built separately. The bicycle path at the high beach is connected to the general bridge. When the rider needs to go to the other side of the river and wants to cross the river, he must take the bicycle through the traction path to the bridge deck on the general bridge. After riding through the bridge deck, take the bicycle in a walking manner. It is quite inconvenient to walk down the bridge; even if there is an elevator on the living side of the embankment, the rider must still pull the bicycle into the elevator, and then the elevator will rise to the height of the bridge and then pass through the fixed bridge. What's more, some bridges only have the design of stepped bicycle traction trails, so the rider must walk the bicycle up and down the bridge in a walking manner, which is quite inconvenient and dangerous.

Therefore, if a special bicycle bridge can be built directly on the high beaches on both sides of the river to connect the bicycle lanes on the high beaches on both sides of the river, the bicycle rider can no longer need to take the bicycle in a walking manner when he has to pass through the river. The line up and down leads not only greatly improves the convenience of riding, but also increases safety. However, there are still many realistic restrictions on the construction of dedicated bicycle bridges directly on the banks of the river. For example, due to the height restrictions of the high beaches, when the water level of the river rises due to rain, the bicycle bridge may be immersed in the river. In the middle, it causes damage or loss of the bridge.

In order to solve the problems related to the immersion of the bicycle bridge in the river due to the rising water level of the river, several design forms of different bicycle bridges have been developed, and the position of the bridge can be adjusted to leave the water surface corresponding to the rise of the water level of the river, for example: buoys Bicycle bridges of the style, folding (or uplifting) and simple detachable design.

The pontoon (board) type bicycle bridge adopts a plurality of pontoons (plates) as the bridge support structure, so that the bridge body floats on the water surface, and after the completion of the construction, the height of the bridge body can be adjusted according to the water level rise and fall. The structure of the buoy (board) type bicycle bridge is easy to apply, but its disadvantage is that the structure of the pontoon is unstable and easy to sway, and it has the risk of being washed away or even lost by the river. It is not suitable for the simple bridge of high river flow velocity and long span. engineering.

The folding bicycle bridge is of a fixed design, some of the bridge body can be folded (or partially lifted), and the bridge type has plasticity; however, since the folded portion of the folding bicycle bridge is limited to the middle spanning bridge portion, and the bridge body is folded After being submerged in the river water, it is not detached, so when the water level rises, the structure may be damaged due to obstructing the water flow. In addition, the folding bicycle bridge needs to be equipped with an operating machine room for folding control and operation, and the structure of the bridge body is complicated and difficult to implement, so the cost of construction and maintenance of the folding bicycle bridge is relatively high.

As for the simple detachable bicycle bridge, it is a short-span structure, which is constructed by using a lighter bridge structure and detachable; the simple detachable bicycle bridge has the advantages of simple structure and low construction cost. However, its bridge system is located in the river channel, with short spans and many piers. It is not convenient to disassemble and disassemble. At the high tide during the flood control period, personnel tools must be prepared for disassembly, and the space for dismantling the bridge body should also be considered.

In view of the above technological developments, the applicant proposes a novel "lifting bicycle bridge and its application method", which is designed not to hinder the flow of water and the section of water passing, and has high stability of the structure of the bridge body, long service life and more The advantages of easy management, flexible operation, and the adjustment of the bridge body can be adjusted at any time.

The invention aims to provide a bicycle bridge design, wherein the height of the bridge body can be adjusted according to the water level of the river to prevent the bridge body from being immersed in the river water and causing damage or loss.

The invention further provides a bicycle bridge construction method, whereby a bicycle bridge is built on the high beach on both sides of the river, and the bicycle bridge built can be directly connected with the bicycle lane without the need to separately build a traction track.

The case can be further explained by the following diagrams and detailed explanations:

Please refer to the first figure, which is a schematic diagram of the structure of the elevating bicycle bridge of the present invention. The elevating bicycle bridge 100 of the present invention is built on the beaches A and B on both sides of the river, and is directly connected to the bicycle lanes 10A and 10B of the high beach and the side with the revetments 11A and 11B, and the bicycle lane 10A, 10B and the bicycle bridge 100 (the dotted line in the figure) do not need to build any climbing track with a large height difference as a connection; therefore, the bicycle rider can ride the bicycle directly by the bicycle lanes 10A, 10B. The road passes through the bridge and reaches the opposite bank.

The lift bicycle bridge 100 of the present invention mainly comprises a bridge body 110, a plurality of pier columns 120, a plurality of pier bases 130 and at least one lifting device 140, wherein the plurality of pier columns 120 are built on the corresponding pier base 130. And supporting the bridge body 110; the lifting device 140 is dynamically connected to the bridge body 110, so that the bridge body 110 can move up and down along the pier 120. Moreover, in a preferred embodiment, the Elevating Bicycle Bridge 100 of the present invention further includes a tie beam 150 that joins the posts 120 to further enhance structural strength. It should be noted that although the present invention is illustrated in the drawings, the lift bicycle bridge 100 may include a tie beam 150. However, those skilled in the art will appreciate that the lift bicycle bridge 100 of the present invention may not be provided with a tie beam 150.

Referring to FIGS. 2A and 2B, respectively, a top view and a side view of the lift bicycle bridge 100 of the present invention are used to illustrate the position of the bridge body 110 of the lift bicycle bridge 100 of the present invention at a normal water level. . When the water level of the river is in a normal state, the bridge body 110 is located at a normal height position N. The bicycle lanes 10A, 10B located at the normal height position N and the high beaches on both sides of the river can be regarded as a continuous bicycle lane as a whole. In other words, at this time, the height between the lane of the bridge body 110 and the bicycle lanes 10A and 10B of the high beach on both sides of the river channel is substantially the same, so that the roadway connecting the bicycle bridge body 110 and the bicycle lanes 10A and 10B is not substantially The height difference, the rider can ride directly through the bicycle.

Please refer to the third and third B drawings, which are a top view and a side view of the lift bicycle bridge 100 of the present invention, for illustrating the position of the bridge body 110 of the lift bicycle bridge 100 of the present invention when the water level rises. . As shown in the figure, when the water level of the river rises or even rises due to rain, the lifting device 140 of the lift bicycle bridge 100 of the present invention raises the whole of the bridge body 110 from the original normal height position N to one according to the change of the water level. The high position H prevents the bridge body 110 from falling into the water surface and causing the bridge to be destroyed. In a preferred embodiment, the lifting device 140 includes one of a winch, chain gear or hydraulic stroke type device, which is an electric lifting unit or a fuel engine unit, and mechanically lifts the bridge under power supply. Body 110. In addition, the lifting device 140 can be fixed above the corresponding pier 120 or move up and down with the end of the bridge body 110. The lifting time of the bridge body 110 is controlled by the lifting device 140, and different lifting times can be set according to different application conditions.

Please refer to the fourth figure, which is a schematic diagram of the application process of the lift bicycle bridge of the present invention. In the lifting bicycle bridge construction method of the present invention, the material of the bridge body can be a steel bridge body, which is pre-built in the factory by cutting, correcting, welding, anti-corrosion and assembly. The lift bicycle bridge of the present invention can also be treated with anti-corrosion treatment by hot dip galvanizing plus color paint coating.

As shown in step 401, the island island cofferdam is first carried out in the river to reduce the water level to the expected depth. In step 402, a plurality of full-casing piles are applied. In step 403, a plurality of pier foundations are applied. In step 404, a plurality of piers are applied, which are placed on the corresponding pier base. In step 405, a lifting device is mounted on the corresponding pier. In step 406, a pre-built bridge body is installed to enable the lifting device to be dynamically connected to the bridge body for bridge lift control. In step 407, a lighting device is implemented. In step 408, an electronic control system is implemented. It must be noted that step 407 and step 408 are interchangeable, and may be applied as an electronic control system before being applied as a lighting device. The electronic control system can be a near-end or digital network remote electronic control system. In step 409, the adjustment and commissioning are performed after the completion of the application. After the application is completed, the lifting device is powered to the bridge body or directly connected to the bridge body, so that the bridge body can move up and down along each of the pier columns.

In the present invention, all of the bridge bodies are in compliance with the "Points for Review of Cross-river Construction Sets". For example, the number of pier foundations and piers according to the present invention is adjusted according to the actual river channel width, so that the center distance between the piers 130 is greater than 40 meters; and the lift bicycle bridge 100 of the present invention is installed in a waterway treatment. In the planned section of the river, the angle between the axis of the pier 130 and the shoulder line of the banks of the river should be greater than 70°. Taking the vicinity of the viewing platform on the lower reaches of the Zhongzheng Bridge in Xindianxi as an example (the first map, the second B map, the third B map, and the real map corresponding to the first map (Annex 1)), the river width at this location is about 165. The meter is arranged in a three-unit span with four piers 120 and a pier base 130, each of which is about 55 meters long and has a width of 6 meters. In addition, the two ends of the lift bicycle bridge of the present invention are approximately the same height as the high beach on both sides of the river, and the elevation is about 6.5 meters (EL 6.5 m, that is, the normal height position N), which is directly connected to the bicycle lane on the high beach, suitable for bicycles and pedestrians. Pass. After the upward rise, the height of the bottom of the bridge body 110 is higher than the height of the embankment of the existing embankment 200A, 200B (about EL 12.48 m, that is, the high position H), which is about the same as the height of the Zhongzheng bridge body. In this case, an operation tower can be set on the pier to monitor the bicycle bridge. For example, the operating tower is placed on the second pier of the Taipei County. In addition, an operating tower can be set at an appropriate location near the dikes 200A, 200B to monitor the bicycle bridge, and an empty bridge is connected to the top of the embankment to facilitate personnel access.

Taking the serial project of the Xindianxi bicycle lane in Taipei County and Taipei City (Zhongzheng Bridge section, see Annex 2) as an example, it is the basic design of the lift bicycle bridge to which the present invention is applied, and the winch equipment is taken as the actual application case. In the lifting device 140 of the present invention, the hoisting height is adjusted according to the actual bridge design. In general, hoist equipment includes: steel brackets, electromagnetic brakes, thrust brakes, reduction gear sets, pulleys, drums, steel cables, winch indicators, and field control equipment. In the above example, the maximum hoisting height of the hoisting machine is about 8 meters. In addition, the number of hoisting equipment can be adjusted according to the required bridge lifting form and the weight of the bridge. It can be built as four or four fixed/sliding, single or two fixed/sliding and one side or single Point fixed/sliding, etc. It can be seen from the above description that the lifting device of the lift bicycle bridge of the present invention can be installed in one, two or four or more. In general, the architecture can be formed in a single group or in a complex array.

In addition to the steel members, the bridge body of the elevating bicycle bridge of the present invention can be constructed of various materials suitable for load or for transportation and pedestrians, and the appearance and road design can also be designed according to the surrounding environment of the river. . For example, the bridge body 110 may include a bicycle lane disposed at a center and a sidewalk disposed at both sides. By means of the invention, a lift bicycle bridge can be built on the high beaches on both sides of the river. The bicycle bridge built can be directly connected to the bicycle lane without the need to build a traction track. The lifting bicycle bridge of the invention is suitable for high-flow channels, and the position of the pier base and the pier column can be adjusted as needed; due to the design of the lifting device, the height of the bridge body can be adjusted at any time during the flood control period without relying on the human machine tool.
