Description

Technical Field

[0001] This utility model relates to the field of river regulation technology, specifically designing a precast concrete dam structure with ecological functions and resistant to water flow impact. Background Technology

[0002] Ecological waterways are created by incorporating ecological principles into traditional waterway construction and management, and by designing projects ecologically based on the current state and function of the waterway. This process aims to construct a waterway aquatic ecosystem and riparian ecosystem that conform to the ecological characteristics of the basin and region, thereby creating an ecological environment suitable for the survival of aquatic organisms in the waterway.

[0003] Traditional river regulation structures, such as groynes (or T-shaped dikes), can prevent direct erosion of riverbanks and thus scour damage, while also improving navigation and maintaining the river's appearance. However, existing groynes and other dams used for waterway regulation are mostly solid structures cast in place, resulting in long construction periods, significant impacts on the aquatic environment, and a lack of ecological function due to their simple structure, which also damages the habitats of aquatic plants and animals. Utility Model Content

[0004] This utility model provides a precast concrete dam structure with ecological functions and resistant to water flow impact, which can solve the technical problem of the inability to unify construction convenience and ecological function in the prior art.

[0005] An ecologically functional precast concrete dam structure resistant to water flow impact includes a dam body composed of multiple precast units stacked in an array along the horizontal and / or vertical direction. A first locking groove and a second locking groove are respectively formed on two opposite sides of the precast unit. A locking member is provided between the first locking groove and the second locking groove, and the locking member connects two adjacent precast units in the horizontal direction. At least one connecting hole is formed on the precast unit, penetrating the other two opposite surfaces of the precast unit, for enabling communication between the water bodies on both sides of the dam body. A groove is formed at the bottom of the precast unit for cooperating with the foundation layer on the riverbed.

[0006] Furthermore, at least one ecological cavity is recessed on the outer surface of the prefabricated unit body, which is a non-through-type containment space for containing ecological substrate.

[0007] Furthermore, the prefabricated unit is a hexahedral block structure with a top surface, a bottom surface, a water-facing surface, a water-repellent surface, and two side surfaces, and the ecological cavity is disposed on the top surface and / or the water-facing surface of the prefabricated unit.

[0008] Furthermore, the opening profile of the ecological cavity is smaller than the profile of its internal space.

[0009] Furthermore, the locking member is a locking beam, with one side of the locking beam located in the first locking groove and the other side of the locking beam located in the second locking groove.

[0010] Furthermore, the locking beam has an I-shaped cross-section.

[0011] Furthermore, the connecting hole is Z-shaped.

[0012] Furthermore, the opening height of the inlet of the connecting hole is greater than that of its outlet.

[0013] Furthermore, both the prefabricated unit and the locking component are prefabricated from high-strength concrete material, and a steel reinforcement skeleton is pre-embedded inside them.

[0014] Furthermore, the ecological cavity is pre-filled with a planting substrate suitable for the growth of aquatic plants, or with gravel filler that can serve as a habitat for aquatic animals. Beneficial effects

[0015] 1. This utility model uses modular prefabricated units to construct the dam body, and integrates 'connecting holes' on each unit to enable water exchange and provide channels for fish, as well as 'ecological chambers' for planting aquatic plants or providing habitats for organisms. Through the structural design itself, it achieves a unity of construction convenience and ecological function.

[0016] 2. The dam structure is constructed by assembling prefabricated units on site using locking components. This overcomes the shortcomings of cast-in-place concrete, which requires high construction water levels and a long time for the dam body to be exposed before pouring. This method offers greater construction convenience and lower construction costs.

[0017] 3. A groove is made at the bottom of the prefabricated unit to match the foundation layer on the riverbed below, so as to enhance the connection strength between the prefabricated unit and the foundation layer, thereby enhancing the dam structure's resistance to water flow impact.

[0018] 4. The ecological cavity adopts an opening profile dimension smaller than its internal space profile dimension, and the resulting inward cavity structure can effectively prevent the loss of the ecological substrate contained inside. Attached Figure Description

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

[0021] like Figures 1-3 As shown, an ecologically functional precast concrete dam structure resistant to water flow impact includes a dam body 10, a dam head 30, and a dam root 40. The dam body 10 is composed of multiple precast units 11 stacked in a horizontal array. The precast units 11 and locking components 20 are both precast from high-strength concrete materials, and steel reinforcement skeletons are pre-embedded inside to ensure structural strength. A first locking groove 16 and a second locking groove 17 are respectively opened on the left and right sides of the precast unit 11. A locking component 20 is provided between the first locking groove 16 and the second locking groove 17, and the locking component 20 connects two adjacent precast units 11 in the horizontal direction. At least one connecting hole 12 is formed on the precast unit 11, penetrating the front and rear surfaces of the precast unit 11, for realizing the connection of water bodies on both sides of the dam body 10. In addition, locking grooves adapted to the locking member 20 are also provided on the dam head 30 and dam root 40, so as to lock the two prefabricated units 11 located at the beginning and end of the dam body 10 to the dam head 30 and dam root 40 respectively.

[0022] In specific implementation, the dam body 10 can also be composed of multiple prefabricated units 11 stacked in a vertical array. When stacked in a vertical array, the first locking groove 16 and the second locking groove 17 are respectively opened on the upper and lower sides of the prefabricated unit 11 in the vertical direction. The dam body 10 can also be composed of multiple prefabricated units 11 stacked in both a horizontal and vertical array. When stacked in both a horizontal and vertical array, the first locking groove 16 and the second locking groove 17 are respectively opened on the left and right sides of the horizontal direction and the upper and lower sides of the vertical direction of the prefabricated unit 11.

[0023] The dam structure described in this example is constructed by assembling prefabricated units on-site using locking components. This overcomes the drawbacks of cast-in-place concrete, which requires excessively high construction water levels and a long dam exposure time for pouring. This method offers greater construction convenience and lower construction costs. Furthermore, each unit is integrated with 'connecting holes' that facilitate water exchange and provide passageways for fish. These holes provide fish with channels for migration and habitation, helping to mitigate complex flow patterns, reduce water flow velocity, and help fish avoid dangerous water conditions. Thus, the structural design itself achieves a balance between construction convenience and ecological function.

[0024] In this embodiment, at least one ecological cavity 13 is recessed on the outer surface of the prefabricated unit 11 body. The ecological cavity 13 is a non-through-type containment space for containing ecological substrate. The ecological cavity 13 is pre-filled with planting substrate suitable for the growth of aquatic plants, or filled with gravel filler that can serve as a habitat for aquatic animals.

[0025] By planting aquatic plants or creating 'ecological chambers' for organisms to inhabit, fish can be provided with good 'living places' and attracted to schools of fish. These places also serve as hiding and shelter, helping fish avoid dangerous water conditions.

[0026] In some embodiments, the prefabricated unit 11 is a hexahedral block structure having a top surface, a bottom surface, a water-facing surface, a water-repellent surface, and two side surfaces, and the ecological cavity 13 is disposed on the top surface and / or the water-facing surface of the prefabricated unit 11.

[0027] Of course, in specific implementation, the prefabricated unit 11 can also be an octahedron, decahedron or other polyhedral block structure.

[0028] See appendix Figure 3 The opening of the ecological cavity 13 has a smaller outline dimension than its internal space, thus forming an inward-facing cavity structure that effectively prevents the loss of the ecological substrate contained within. Furthermore, during implementation, the opening of the ecological cavity 13 can be triangular, circular, or another type of polygon.

[0029] Preferably, the locking member 20 is a locking beam, with one side of the locking beam located in the first locking groove 16 and the other side located in the second locking groove 17. This facilitates the connection between adjacent prefabricated units 11 and between prefabricated units 11 and the dam head 30 or dam root 40.

[0030] In some preferred embodiments, the first locking groove 16 and the second locking groove 17 are both T-shaped, and the cross-section of the locking beam is I-shaped. The locking fit structure of the T-shaped locking groove and the I-shaped locking beam not only facilitates the manufacturing and shaping of the locking beam, but also makes it convenient to carry out on-site assembly and construction of the dam structure, and the stability of the dam structure after construction is reliable.

[0031] Of course, in practice, the locking beam can also be other structures with the same function, such as dumbbell shape, etc.

[0032] See appendix Figure 1 and attached Figure 3 The projection of the connecting hole 12 in the vertical direction is Z-shaped. The Z-shape allows the connecting hole 12 to have a better energy dissipation effect, which is more conducive to weakening complex flow patterns and reducing water flow velocity, thus making it easier for fish to pass through.

[0033] A further preferred embodiment is that the inlet of the connecting hole 12 is located on the water-facing side of the dam body 10, and the outlet of the connecting hole 12 is located on the water-repellent side of the dam body 10. Furthermore, the opening height of the inlet of the connecting hole 12 is greater than that of its outlet, thereby facilitating better connection between the water bodies on both sides of the dam body 10.

[0034] In practice, the connecting hole 12 can be a round hole, a triangular hole, a square hole, or other shapes. For ease of construction, a round hole is preferred in this example. The number of connecting holes 12 can be one or more.

[0035] When necessary, the connecting hole 12 can also adopt a structural design with a high middle section and low outlets at both ends, such as... Figure 3 As shown, this design makes the connecting hole 12 less likely to be blocked by impurities in the water, thus ensuring that the connecting hole 12 can be used normally for a long time.

[0036] At least two lifting lugs 15 are provided on the top of the prefabricated unit 11 to facilitate the hoisting and on-site assembly of the prefabricated unit 11; at the same time, a groove 14 is provided at the bottom of the prefabricated unit 11 to facilitate its cooperation with the foundation layer on the riverbed below, thereby enhancing the connection strength between the prefabricated unit and the foundation layer, and thus enhancing the dam structure's resistance to water flow impact.

[0037] In practice, the cross-section of the groove 14 can be rectangular, inverted trapezoidal, inverted T-shaped, etc., so as to enhance the connection strength between the prefabricated unit and the foundation layer after cooperating with the foundation layer on the riverbed below.

[0038] Working principle: The dam structure described in this embodiment consists of a dam body 10, a dam head 30, and a dam root 40. The dam body 10 is composed of multiple prefabricated units 11 stacked in a horizontal array. Adjacent prefabricated units 11, as well as the two prefabricated units 11 at the beginning and end of the dam body 10, and the dam head 30 and dam root 40, are connected using the same locking mechanism. This modular prefabricated unit construction allows for the dam body to be constructed. Each unit integrates a 'connecting hole' that facilitates water exchange and provides a passage for fish, as well as an 'ecological cavity' for planting aquatic plants or providing habitats for organisms. The structural design itself achieves a balance between construction convenience and ecological function. Furthermore, the use of prefabricated units assembled on-site with locking components overcomes the drawbacks of cast-in-place concrete, which requires high construction water levels and a long dam exposure time for pouring. This results in greater construction convenience and lower construction costs. In addition, the ecological cavity's opening profile is smaller than its internal space profile, creating a recessed cavity structure that effectively prevents the loss of the contained ecological matrix.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
