[0031] Example

[0032] like Figures 1 to 5 As shown, the integrated lake tunnel and culvert tunnel and navigation structure includes an underwater tunnel structure 2, and a navigation box culvert structure 1 is provided below the open section of the underwater tunnel structure 2 near the shore road surface;

[0033] The inner cavity 4 of the navigation box culvert structure 1 is used to connect the waters on both sides of the underwater tunnel structure 2;

[0034] The tunnel structure bottom plate of the underwater tunnel structure 2 in the open section is used as the top plate of the navigation box culvert structure 1, and the part close to the shore road surface is suspended with a box culvert structure;

[0035] The tunnel structure top plate of the underwater tunnel structure 2 is connected at the position of the open section through the turning structure system 7;

[0036] The turning structure system 7 also serves as a tunnel walkway;

[0037] The top plate of the navigation box culvert structure 1 extends toward the shore road surface to form a plank road plate 6 and a sidewalk located in the water area;

[0038] The joints between the side wall 11 of the navigation box culvert structure 1 and the revetment structure 8 of the shore road surface are connected by water-stopping measures 9 to achieve longitudinal fixation;

[0039] The navigation box culvert structure 1 and the underwater tunnel structure 2 adopt unified anti-floating and uneven settlement measures 5, or use deformation joints to resist uneven settlement requirements;

[0040] The connection angle between the navigation box culvert structure 1 and the underwater tunnel structure 2 is 30° to 150°.

[0041] The utility model is designed in combination with the requirements of the tunnel structure 2 stress, the box culvert structure 1 stress and the passage of ships to realize navigation. The underwater tunnel structure 2 and the navigation box culvert structure 1 are comprehensively applied to realize navigation in the waters on both sides of the underwater tunnel structure 2 through the navigation box culvert structure 1, thereby enhancing the navigation capacity of the water body.

[0042] By implementing the navigation box culvert structure 1 in the space below the open section, the connectivity and navigation capacity of the water area are effectively guaranteed.

[0043] The top plate of the navigation box culvert structure 1 is extended to form a plank road plate, which not only meets the landscape requirements, but also provides more functional use space and helps maintain ecological balance.

[0044] In some embodiments, green plants are provided on the plank board 6 .

[0045] In some embodiments, a retaining wall structure 3 is provided between the sidewalk and the plank road 6 as a partition.

[0046] The top plate of the navigation box culvert structure 1 extends toward the shore road surface to form a plank road slab 6 located in the water area, and its structural force system should meet the needs of ship passage; at the same time, a retaining wall structure 3 is set on the outside of the sidewalk as a partition to prevent river water from flowing back into the tunnel after the water level in the shore section rises.

[0047] In some embodiments, high-pressure jet grouting piles are used as water-stopping measures 9 to connect the side wall 11 of the navigation culvert structure 1 and the revetment structure 8 of the shore road surface.

[0048] The above technical means can prevent the side wall 11 of the navigation box culvert structure 1 from being separated from the revetment structure 8 of the shore road surface.

[0049] In some embodiments, the unified anti-floating and uneven settlement measures 5 refer to the unified use of anti-pulling piles.

[0050] In some embodiments, the deformation joint between the navigation culvert structure 1 and the underwater tunnel structure 2 is arranged at a position after the underwater tunnel structure 2 crosses the plank road plate 6 .

[0051] The location of the above-mentioned deformation joints can form an independent earthquake-resistant and uneven settlement force-bearing system.

[0052] In certain embodiments, the section of the navigation box culvert structure 1 located on the shore cannot adopt a wall structure in its entirety, and an open beam-column structure system may be partially adopted.

[0053] Since the section of the navigation box culvert structure 1 located on the shore should take into account the navigation connectivity requirements, it is not appropriate to use a wall structure for the entire section, and an open beam-column structure system should be used partially.

[0054] From a design perspective, the integrated tunnel and navigation structure of the lake tunnel box culvert usually includes a waterproof layer, a bearing layer and a protective layer. The combination of these layers ensures the long-term stability and safety of the structure. In addition, the design of this structure allows the formation of a stable navigation channel underwater, thus providing a reliable transportation solution.

[0055] The utility model also provides a construction method for a lake tunnel box culvert integrated tunnel and a navigation structure, comprising the following steps:

[0056] Step 1: construct anti-pullout piles to form uneven settlement measures 5;

[0057] Step 2: construct slope support, support formed by SMW piles, Larsen steel sheet piles, bored piles and water-stop curtains for the navigation box culvert structure 1 and the submerged part of the underwater tunnel structure 2;

[0058] Step 3, construct the bottom plate, side wall and column structure 1 of the navigation box culvert structure 1;

[0059] Step 4: construct the bottom plate structure, the turning structure system 7 and the plank road plate 6 of the underwater tunnel structure 2;

[0060] Step 5: construct the side wall 11 and the revetment structure 8 of the navigation box culvert structure 1;

[0061] Step 6: construct high-pressure jet grouting piles at the connection between the revetment structure 8 and the underwater tunnel structure 2 as a water-stopping measure 9;

[0062] Step 7: backfill the earth on the plank road slab 6.

[0063] The construction method of the utility model adopts open-cut construction, and the lake body is constructed by slope excavation. The underwater tunnel structure 2 and the navigation box culvert structure 1 are supported by SMW piles, Larsen steel sheet piles, bored cast-in-place piles + water-stop curtains, etc. in combination with geological conditions and tunnel bottom burial depth.

[0064] The application of this utility model not only fills the application gap of traditional underwater navigation structures under specific environmental conditions, but also promotes the progress of underwater construction technology. This innovative design and construction method has high application value and market potential, meets the dual needs of modern engineering projects for environmental protection and technological innovation, and provides valuable reference and technical support for similar projects in the future.

[0065] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
