In river management, the dike box culvert can be used as an effective alternative to traditional flood control structures.
[0003] The construction process of the dike box culvert includes foundation excavation, box culvert installation, pipeline connection, sealing and fixing, and testing and acceptance. During the construction process, it is necessary to ensure that the position and angle of the box culvert are correct, and take effective fixing measures to prevent the box culvert from moving or breaking. In addition, when connecting the pipes, it is necessary to ensure the sealing and firmness of the connection to prevent water leakage. When filling the sealing materials and fixing the equipment, it is necessary to pay attention to the surrounding environment and ecological protection to minimize the impact on the environment and ecology. Finally, an acceptance test is required after the installation is completed to ensure the normal operation of the dike box culvert.

[0027] Embodiment 1
[0028] See also Figure 1-Figure 5 , a box culvert outlet through the dike of an ecological dike project. In this embodiment, the box culvert outlet through the dike can be used in the field of water conservancy projects, such as hydropower stations, large reservoirs, flood prevention and control projects, etc.
[0029] Specifically, the present embodiment includes a buried box culvert structure 1 having a hollow passage connected to the outside for discharging water, an energy dissipation pool structure 2 is disposed at the outlet of the box culvert structure 1, and a drainage system 3 is disposed on the energy dissipation pool structure 2.
[0030] Among them, the through-embankment box culvert can ensure that the hydrological process of the river is not affected, maintaining the natural attributes and ecological functions of the river. It can also effectively improve the flood control capacity of the embankment project. The box culvert structure 1 can be cast in situ with C25 reinforced concrete, the size of the hollow channel can be 1.2m×2.0m, and the thickness of the bottom plate, top plate and side wall can all be 0.3m.
[0031] By setting up the energy dissipation pool structure 2 to optimize the outlet outside the through-embankment box culvert, the water flow velocity out of the through-embankment box culvert can be reduced compared to the unoptimized box culvert outlet, reducing the scouring and damage to the river channel at the outlet, so as to protect the safety of the embankment. The size of the energy dissipation pool structure 2 can be 10m×10m (length×width). During construction, a seepage pool is excavated at the bottom of the energy dissipation pool structure 2, backfilled with sand and pebbles, and then the energy dissipation pool structure 2 is cast with C20 concrete. When in use, the water entering the energy dissipation pool structure 2 is drained down through the drainage system 3.
[0032] As a more specific implementation of this embodiment, in order to disperse the water collected and flowing out of the box culvert structure 1 and reduce the impact pressure. The water outlet of the box culvert structure 1 is connected to the energy dissipation pool structure 2 through a diffusion belt structure 4. In addition, the diffusion belt structure 4 can also disperse the water flowing out of the box culvert structure 1 to a wider area, so as to give full play to the energy dissipation effect of the energy dissipation pool structure 2. The above-mentioned connection method can be connected on the same horizontal plane, or it can be connected in a stepped manner from the box culvert structure 1 to the energy dissipation pool structure 2.
[0033] As a more specific implementation of this embodiment, the diffusion belt structure 4 includes a diffusion bottom plate 5 connected to the bottom of the box culvert structure 1, and protective side plates 6 extending along both sides of the box culvert structure 1. The diffusion bottom plate 5 can be a 0.3m thick C20 concrete bottom plate. The protective side plates 6 on both sides can be 0.3m thick and cast in situ using C20 concrete.
[0034] In order to diffuse the water flow, the diffusion bottom plate 5 is in an outward-facing "X" shape toward the water outlet direction, and the two protective side plates 6 are also arranged in an outward-facing "X" shape. The opening of the outward-facing "X" shape can be adjusted according to the size of the energy dissipation pool structure 2. Generally, the end spacing of the outward-facing "X" shape after opening is greater than half of the width of the energy dissipation pool structure 2.
[0035] As a more specific implementation of this embodiment, in order to save construction materials, the setting height of the two protective side panels 6 is gradually reduced toward the water outlet direction. Because the water flow just flowing out of the box culvert structure 1 is deep, and the depth of the water flow after being diffused through the diffuser bottom plate 5 in the shape of an outward eight will gradually decrease. Therefore, the bevel setting of the two protective side panels 6 can not only ensure the passage and diffusion of water flow, but also reduce the pouring volume of C20 concrete. In addition, the bevel support of the protective side panels 6 also helps to consolidate the box culvert structure 1.
[0036] As a more specific implementation of this embodiment, the energy dissipation pool structure 2 includes an energy dissipation base plate 7 connected to the diffusion base plate 5, and the drainage system 3 includes a plurality of drainage holes 8 arranged on the energy dissipation base plate 7 and penetrating the energy dissipation base plate 7. The energy dissipation base plate 7 is surrounded by an energy dissipation sill 9 on the side facing the water outlet and diffusion direction. The energy dissipation base plate 7 can be a rectangular, trapezoidal or other structure, which is used to receive the water flow diffused by the diffusion zone structure 4, and to prevent impact and dissipate energy through the energy dissipation sill 9. The collected water flow is quickly discharged through the drainage holes 8, which can avoid causing a large uplift pressure and effectively protect the energy dissipation floor 7. In addition, the energy dissipation sill 9 can be 0.5m higher than the energy dissipation base plate and have a top width of 0.5m.
[0037] As a more specific implementation of this embodiment, a plurality of the drainage holes 8 are arranged at intervals and in a plum blossom shape, and the interval distance is 0.5-3.5m. Preferably, the interval distance of the drainage holes 8 can be 2m, and the number of drainage holes distributed at this interval can basically achieve the rapid discharge of the accumulated water in the energy dissipation pool. Of course, the drainage speed is also related to the aperture size of the drainage hole 8, and the diameter of the pipe can be selected to drain water.
[0038] As a more specific implementation of this embodiment, a plurality of the drainage holes 8 are provided with drainage pipes 10. The pre-arrangement of the drainage pipes 10 helps to form the drainage holes 8 when pouring the energy dissipation base plate 7, and ensures the hole size requirements. The drainage pipes 10 can be DN50PVC drainage pipes to meet the pouring strength requirements.
[0039] As a more specific implementation of this embodiment, in order to alleviate the impact of water flow on the energy dissipation sill 9, the energy dissipation sill 9 is provided with an inclined edge 11 on one side close to the energy dissipation bottom plate 7. The inclined edge 11 can prevent the water flow from directly impacting the energy dissipation sill 9 and improve the service life of the energy dissipation sill 9.
