Description

Technical Field

[0001] This utility model relates to a water crossing road, and more particularly to a water crossing road constructed by combining an underwater tunnel and a bridge. Background Technology

[0002] With the acceleration of urbanization, the transportation connection between cities and waterways is becoming increasingly important. However, traditional transportation infrastructure often cannot meet the rapidly growing demand for motorized and non-motorized traffic, leading to problems such as traffic congestion and low traffic efficiency. Furthermore, the presence of waterways presents new challenges for transportation route design, especially in urban expansion and infrastructure construction, where effectively utilizing water space has become a key task.

[0003] In existing underwater tunnels, non-motorized vehicle lanes and motorized vehicle lanes are mixed, making management difficult. In recent years, with the popularization of electric vehicles and other non-motorized vehicles, related management challenges have become increasingly prominent due to issues such as battery combustion, excessive speed, and mixing with motorized vehicles. Existing traffic solutions typically employ a single bridge or tunnel design, which is insufficient to simultaneously meet the traffic needs of both motorized and non-motorized vehicles. Furthermore, existing bridge designs often neglect the independence of pedestrian and non-motorized vehicle lanes, leading to safety hazards.

[0004] Although some projects have incorporated multi-level or multi-compartment passage concepts into their designs, there is still a lack of mature technical solutions for effectively combining underwater tunnels and bridges when crossing waterways. Therefore, there is an urgent need for a new type of transportation structure system that can achieve layered passage for motor vehicles and non-motor vehicles while ensuring safety and making rational use of water space. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a water crossing lane that combines an underwater tunnel and a bridge, which allows the bridge and tunnel to share the passage space, greatly improving traffic efficiency, alleviating ground traffic congestion, and protecting the aquatic environment.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is to provide a water crossing road jointly constructed by an underwater tunnel and a bridge, including an underwater tunnel and a bridge arranged in layers. The underwater tunnel includes several motor vehicle lanes, and tunnel structure piles are arranged below the motor vehicle lanes. The bridge includes parallel non-motor vehicle lanes and pedestrian walkways, and railings are arranged on the outer side of the non-motor vehicle lanes and pedestrian walkways. The non-motor vehicle lanes, pedestrian walkways and railings are arranged on bridge piles, and the bridge piles are formed by the two outermost tunnel structure piles extending upwards.

[0007] Furthermore, the tunnel structure piles are constructed with pre-reserved reinforcing steel bars as foundation reinforcement for bridge piles.

[0008] Furthermore, the non-motorized vehicle lanes and pedestrian walkways are located above the water area and are symmetrically distributed on both sides of the bridge piles.

[0009] Furthermore, the motor vehicle lane is a two-way traffic lane, and the tunnel structure piles are five in number, evenly distributed below the motor vehicle lane.

[0010] To solve the aforementioned technical problems, this utility model also provides another type of waterway crossing road jointly constructed with an underwater tunnel and a bridge. This includes a layered underwater tunnel and bridge. The underwater tunnel includes several motor vehicle lanes, with tunnel structure piles installed below each lane and two tunnel protection piles installed below the outer side of each lane. The bridge includes parallel non-motorized vehicle lanes and pedestrian walkways, with railings installed on the outer side of each lane. The non-motorized vehicle lanes, pedestrian walkways, and railings are mounted on bridge piles, which are formed by extending upwards from the tunnel protection piles.

[0011] Furthermore, the tunnel protective piles are constructed with pre-reserved reinforcing steel bars to serve as the foundation reinforcement for the bridge piles.

[0012] Furthermore, the non-motorized vehicle lanes and pedestrian walkways are located above the water area and are symmetrically distributed on both sides of the bridge piles.

[0013] Furthermore, the motor vehicle lane is a two-way traffic lane, and the tunnel structure piles are five in number, evenly distributed below the motor vehicle lane.

[0014] Furthermore, the depth to which the tunnel protective piles are inserted into the foundation is greater than the depth to which the tunnel structural piles are inserted into the foundation.

[0015] This invention offers the following advantages over existing technologies: The underwater tunnel and bridge combined construction of this waterway crossing allows for layered traffic flow by integrating the two: the tunnel section is designed specifically for motor vehicles, while the bridge section is for non-motorized vehicles and pedestrians. The pedestrian and motor vehicle lanes are independently designed, thus improving traffic safety. The bridge for non-motorized vehicles can be designed as a scenic bridge, enhancing the aesthetics of the area; while the underwater tunnel ensures unimpeded passage. This technology can be widely applied to urban expansion, traffic network optimization, and the sustainable use of water resources. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Figure 1 This is a schematic diagram of the underwater tunnel and bridge combined construction structure for crossing a waterway, according to this utility model.

[0022] Please see Figure 1 The present invention provides a waterway crossing road constructed by combining an underwater tunnel and a bridge, comprising a layered underwater tunnel 1 and a bridge 2. The underwater tunnel 1 includes several motor vehicle lanes 11, with tunnel structure piles 12 installed below each motor vehicle lane 11. The bridge 2 includes parallel non-motor vehicle lanes 21 and pedestrian walkways 22, with railings 23 installed on the outer sides of the non-motor vehicle lanes 21 and pedestrian walkways 22. The non-motor vehicle lanes 21, pedestrian walkways 22, and railings 23 are installed on bridge piles 24, which are formed by extending upwards from the two outermost tunnel structure piles 12.

[0023] This utility model provides a water-crossing roadway constructed by combining an underwater tunnel and a bridge. The underwater tunnel 1 is specifically designed for motor vehicle traffic, ensuring safe underwater driving and avoiding safety hazards caused by mixing with non-motorized vehicles and pedestrians. Secondly, the bridge 2 provides independent space for non-motorized vehicles and pedestrians. The bridge design can incorporate landscaping elements to enhance the visual appeal of the area. The independent setting of pedestrian and non-motorized vehicle lanes further improves traffic safety and reduces traffic accidents. Furthermore, this utility model fully considers the protection of the aquatic environment, integrating the tunnel and bridge construction. The bridge can utilize the tunnel structure as its foundation, transferring forces to pile foundations through the sidewalls of the tunnel's main structure, or utilizing the tunnel's retaining structure pile foundations. Through reasonable design and construction, the impact on the aquatic ecosystem is minimized. The implementation of this structure will significantly improve traffic efficiency, alleviate urban traffic congestion, and provide innovative solutions for urban expansion and infrastructure construction.

[0024] In a preferred embodiment, the tunnel structure piles 12 of this invention have pre-reserved reinforcing steel bars as foundation reinforcement for the bridge piles 24 during construction; this allows for the continuation of subsequent bridge structure construction after the foundation structures are completed. This approach not only improves construction efficiency but also enhances the overall structural safety and reliability.

[0025] The underwater tunnel and bridge combined construction of the present invention provides a water crossing lane, wherein the non-motorized vehicle lane 21 and the pedestrian walkway 22 are located above the water area 3 and are symmetrically distributed on both sides of the bridge pile 24.

The underwater tunnel 1 includes several motor vehicle lanes 11, and tunnel structure piles 12 are arranged below the motor vehicle lanes 11. Two tunnel protection piles 13 are arranged below the outer side of the motor vehicle lanes 11. The bridge 2 includes parallel non-motor vehicle lanes 21 and pedestrian walkways 22. Railings 23 are arranged on the outer side of the non-motor vehicle lanes 21 and pedestrian walkways 22. The non-motor vehicle lanes 21, pedestrian walkways 22 and railings 23 are arranged on bridge piles 24, which are formed by extending upward from the tunnel protection piles 13.

[0028] The underwater tunnel and bridge combined construction of this utility model provides a waterway crossing, in which the tunnel protection pile 13 is pre-reserved with reinforcing steel bars as the foundation steel bars for the bridge pile 24. Preferably, the depth to which the tunnel protection pile 13 is inserted into the foundation is greater than the depth to which the tunnel structure pile 12 is inserted into the foundation, thereby further improving the bearing capacity and stability of the overall structure.

[0029] In summary, this utility model provides a water-crossing roadway that combines an underwater tunnel and a bridge, aiming to effectively solve the traffic connection problem between cities and waterways and meet the ever-increasing traffic demands of motor vehicles and non-motor vehicles. Through rational design and construction, this structure achieves layered traffic for motor vehicles and non-motor vehicles, ensuring the safe and efficient use of all types of transportation. Simultaneously, while considering environmental protection, the integrated tunnel and bridge design reduces the impact on the aquatic ecosystem, improves traffic efficiency, and effectively alleviates urban traffic congestion.
