Description
Technical Field
[0001] This utility model belongs to the field of municipal engineering and highway engineering technology, and more specifically, it relates to a riverside ecological landscape passage structure. Background Technology
[0002] With the rapid advancement of urbanization in major cities, the connections between various areas within cities are becoming increasingly close. To meet transportation requirements, the construction of municipal or highway channels in riverside areas such as those near rivers, lakes, and lakes has become the preferred solution. Bridge construction or tunnel construction are currently the commonly used methods. The specific method to be adopted depends on a comprehensive comparison of engineering geological conditions, engineering hydrological conditions, and surrounding environmental landscape requirements.
[0003] When constructing municipal or highway passages via bridges in riverside areas such as those near rivers, lakes, or other waterfront locations, it is necessary to comprehensively consider factors such as the current surrounding environment and long-term land use planning. Generally speaking, bridge solutions have disadvantages such as significant noise impact, poor aesthetic appeal, and low integration with the surrounding environment. Typically, when bridges are near sensitive buildings, soundproofing measures such as soundproof enclosures are used to reduce noise pollution, further diminishing the aesthetic appeal.
[0004] When constructing municipal or highway passages along rivers, lakes, or other riverside areas using the cut-and-cover method, a comprehensive comparison must be made considering engineering geological conditions, hydrological conditions, and the protection of surrounding buildings. When using the mining method for cut-and-cover tunneling, the strata must possess a certain degree of self-stability; ground reinforcement may be necessary to ensure waterless operation. When strata conditions are poor, controlling ground deformation is difficult and can easily have adverse effects on surrounding buildings, especially in riverside areas such as those near rivers, lakes, or other riverside locations, where the cut-and-cover tunnel scheme may experience bias pressure issues on the riverside or lakeside side. Overall, the cut-and-cover method minimizes the impact on the surrounding environment after completion (low noise pollution, no impact on the surrounding landscape, and high integration with the surrounding environment). However, during construction, to protect surrounding buildings, there are many restrictions on route selection, and high requirements for engineering geology and environmental protection. It is suitable for areas with good strata conditions, no groundwater, and open surrounding ground.
[0005] Therefore, it is necessary to study a channel structure that is suitable for various geological conditions, has minimal noise impact on the surrounding area, no impact on the surrounding landscape, and a high degree of integration with the surrounding environment, so as to meet the requirements of urban riverside ecological landscape.

[0007] To achieve the above objectives, this utility model provides a riverside ecological landscape passage structure, including a left passage and a right passage set on the riverside soil. The left passage is set closer to the riverside soil, and the right passage is set closer to the water. The left passage is a box culvert-type cast-in-place concrete structure. The water-facing side of the left passage is provided with a first ventilation hole.

[0029] Example 1
[0030] Please see Figure 1This utility model embodiment 1 provides a riverside ecological landscape passage structure, including a left passage 1 and a right passage 2 set on the riverside soil. The left passage 1 is located closer to the riverside soil, and the right passage 2 is located closer to the water. The left passage 1 is a box culvert-type cast-in-place concrete structure. The water-facing side of the left passage 1 is provided with a first ventilation hole 1-1. The upper side of the left passage 1 is backfilled with a first backfill soil 1-2, and green plants are planted on the first backfill soil 1-2. In this embodiment, the left passage 1 and the right passage 2 are arranged in a staggered manner, and the water-facing side of the left passage 1 and the right passage 2 are both open-air. The existing topographic line 3-1 is the existing topographic line of the riverside soil, that is, the topographic line before the construction of the passage structure; the topographic line 3-2 after backfilling is the topographic line after the construction of the passage structure.
[0031] The passage structure in this embodiment can be constructed using either slope excavation or vertical excavation, depending on the specific topography and geological conditions of the riverside soil. When using slope excavation, shotcrete and anchor support can be used for tiered slope reduction; that is, shotcrete and anchor structures 2-1 are installed on both the left and right sides of the passage 2 closest to the riverside soil. When the surrounding environment has buildings or pipelines that need protection, or when traffic cannot be interrupted, and the slope reduction scheme is constrained, bored pile support can be used. In some schemes, to ensure that the width of the right passage 2 meets the usage requirements, a second backfill soil 2-3 is needed to backfill the excavated riverside soil, i.e., the area between the lower side of the right passage 2 and the existing topographic line 3-1, to the designed width.
[0032] Furthermore, in this embodiment, a gravity retaining wall 2-2 is also provided on the water-facing side of the right-hand passage 2 as a support structure.
[0033] When the water level is high, to ensure waterless operation of the gravity retaining wall 2-2 and meet the bearing capacity requirements of the lower part, this embodiment further suggests that a temporary sealing method, such as an earth-rock cofferdam 2-4 or sheet pile support, can be used on the water-facing side of the gravity retaining wall 2-2. The earth-rock cofferdam 2-4 or sheet piles will be removed after the gravity retaining wall 2-2 and the roadbed backfilling are completed. Whether or not to install the earth-rock cofferdam 2-4 needs to be determined based on the water level. If the water level is lower than that of the gravity retaining wall 2-2, the earth-rock cofferdam 2-4 may not be required.
[0034] After the completion of the passage structure in this implementation, ecological restoration can be carried out by covering the top slab of the left passage 1 with soil according to the original terrain. That is, the first backfill soil 1-2 is used to backfill the upper side of the left passage 1. For the slope formed after the soil covering restoration, greening measures such as planting grass can be used for ecological restoration.
[0035] This utility model provides a riverside ecological landscape passage structure by setting up a left passage 1 and a right passage 2 on the riverside soil. The left passage 1 is a cast-in-place box culvert concrete structure, and the right passage 2 is located near the water. This passage structure is formed by excavating the waterside soil on the riverside soil and then casting the left passage 1 as a cast-in-place box culvert concrete structure. Compared with the existing underground tunnel laying method, the passage structure of this utility model is not limited by geological conditions and can be constructed under various geological conditions, making it suitable for various geological conditions. The cast-in-place box culvert concrete structure of the left passage 1 can isolate noise from spreading outwards and reduce the impact of noise on the surrounding area. The first ventilation hole 1-1 set on the waterside side of the left passage 1 can ensure that the left passage 1 can be naturally ventilated. After backfilling the upper side with the first backfill soil 1-2 and planting greenery, the passage structure has no impact on the surrounding landscape and has a high degree of integration with the surrounding environment. It can restore the original landform to the greatest extent and meet the requirements of urban riverside ecological landscape effect.
[0036] Example 2
[0037] Please see Figure 2 Embodiment 2 of this utility model provides a riverside ecological landscape passage structure, including a left passage 1 and a right passage 2 set on the riverside soil. The left passage 1 is set closer to the riverside soil side, and the right passage 2 is set closer to the water side. Both the left passage 1 and the right passage 2 are cast-in-place box culvert-type concrete structures. The water side of the left passage 1 is provided with a first ventilation hole 1-1, and the water side of the right passage 2 is provided with a second ventilation hole 2-5. The upper side of the left passage 1 is backfilled with a first backfill soil 1-2, and the upper side of the right passage 2 is backfilled with a third backfill soil 2-6. Green plants are planted on both the first backfill soil 1-2 and the third backfill soil 2-6. In this embodiment, the left passage 1 and the right passage 2 are arranged in a stacked manner, and the water side of both the left passage 1 and the right passage 2 are exposed. The existing topographic line 3-1 is the existing topographic line of the riverside soil, that is, the topographic line before the construction of the passage structure; the topographic line 3-2 after backfilling is the topographic line after the construction of the passage structure.
[0038] The passage structure in this embodiment can be constructed using either slope excavation or vertical excavation, depending on the specific topography and geological conditions of the riverside soil. When slope excavation is used, shotcrete and anchor support can be employed for gradual slope reduction, meaning that shotcrete and anchor structures 2-1 are installed on both the left and right sides of the passage 2 closest to the riverside soil. When the surrounding environment requires protection for buildings and pipelines, or when traffic cannot be interrupted, and the slope reduction scheme is constrained, bored pile support can be used for reinforcement.
[0039] In addition, gravity retaining walls and / or earth-rock cofferdams and other retaining structures can also be installed on the water-facing side of the right-hand passage 2 in this embodiment.
[0040] After the completion of the passage structure, ecological restoration can be carried out by covering the top slab of the left passage 1 and the top slab of the right passage 2 with soil according to the original terrain. Specifically, the top side of the left passage 1 will be backfilled with the first backfill soil 1-2, and the top side of the right passage 2 will be backfilled with the third backfill soil 2-6. For the slopes formed after the soil restoration, ecological restoration can be carried out by planting grass and other greening measures.
[0041] This utility model provides a riverside ecological landscape passage structure by constructing a left passage 1 and a right passage 2 on the riverside soil. Both left passage 1 and right passage 2 are cast-in-place box culvert-type concrete structures, with the right passage 2 located closer to the water's edge. This passage structure is formed by excavating the waterside soil on the riverside soil and then casting the left and right passages 1 and 2 as box culvert-type concrete structures. Compared to existing underground tunnel construction methods, the passage structure of this utility model is not limited by geological conditions and can be constructed under various geological conditions, making it suitable for various geological environments. The left and right passageways 1 and 2 of the box culvert-type cast-in-place concrete structure can isolate noise from spreading outwards and reduce the impact of noise on the surrounding area. The first ventilation hole 1-1 on the water-facing side of the left passageway 1 and the second ventilation hole 2-5 on the water-facing side of the right passageway 2 can ensure natural ventilation for the left and right passageways 1 and 2. After backfilling the upper side with the first backfill soil 1-2 and the third backfill soil 2-6 and planting greenery, the passageway structure will have no impact on the surrounding landscape and will be highly integrated with the surrounding environment. It can restore the original landform to the greatest extent and meet the requirements of the urban riverside ecological landscape effect.

The water side of the left passage 1 is provided with a first ventilation hole 1-1. The upper side of the left passage 1 is backfilled with a first backfill soil 1-2, and green plants are planted on the first backfill soil 1-2. In this embodiment, the left passage 1 and the right passage 2 are arranged in parallel, and the water side of the left passage 1 and the right passage 2 are both set in the open. The existing topographic line 3-1 is the existing topographic line of the riverside soil, that is, the topographic line before the construction of the passage structure; the topographic line 3-2 after backfilling is the topographic line after the construction of the passage structure.
[0044] The passage structure in this embodiment can be constructed using either slope excavation or vertical excavation, depending on the specific topography and geological conditions of the riverside soil. When slope excavation is used, shotcrete and anchor support can be employed for gradual slope reduction, meaning that shotcrete and anchor structures 2-1 are installed on both the left and right sides of the passage 2 closest to the riverside soil. When the surrounding environment requires protection for buildings and pipelines, or when traffic cannot be interrupted, and the slope reduction scheme is constrained, bored pile support can be used for reinforcement.
[0045] In addition, gravity retaining walls and / or earth-rock cofferdams and other retaining structures can also be installed on the water-facing side of the right-hand passage 2 in this embodiment.
[0046] After the completion of the passage structure in this implementation, ecological restoration can be carried out by covering the top slab of the left passage 1 with soil according to the original terrain. That is, the first backfill soil 1-2 is used to backfill the upper side of the left passage 1. For the slope formed after the soil covering restoration, greening measures such as planting grass can be used for ecological restoration.
[0047] This utility model provides a riverside ecological landscape passage structure by setting up a left passage 1 and a right passage 2 on the riverside soil.

It can restore the original landform to the greatest extent and meet the requirements of urban riverside ecological landscape effect.
[0048] The passageway structure of this utility model embodiment can adopt various arrangements such as staggered, overlapping, and parallel arrangements. The specific arrangement needs to be determined after comprehensive consideration of the surrounding environment, terrain conditions, and route layout. The road surface elevation should be at least 1 meter higher than the 100-year flood level. The passageway structure is made of cast-in-place concrete, with a concrete strength generally between C30 and C35, and a permeability grade generally between P8 and P10.
