When the plurality of base members 4 are longitudinally arranged in series, the tooth plates 42 are longitudinally connected in rows, and the plurality of rows of tooth plates 42 are arranged in the transverse direction. In this embodiment, Figure 2 The left-right direction is the transverse direction, the vertical plane direction is the longitudinal direction, and the dam body is assembled in the longitudinal direction.

[0050] The bottom plate 41 corresponding to one of the tooth plates 42 is provided with a front tenon 43 and a rear mortise 45 at the front and rear end faces, respectively, and the bottom plate 41 corresponding to the other tooth plate 42 symmetrically arranged in the transverse direction is provided with a front mortise 44 and a rear tenon 46 at the front and rear end faces, respectively.

[0051] Figure 3 The left lower end is the longitudinal front end of the dam bottom structure 1, and the right upper end is the longitudinal rear end of the dam bottom structure 1. In this embodiment, the front tenon 43 and the rear mortise 45 of the base member 4 are arranged on the bottom plate 41 corresponding to the second tooth plate 42 on one side of the base member 4 in the transverse direction (right side in this embodiment), Figure 4 and the front mortise 44 and the rear tenon 46 are arranged on the bottom plate 41 corresponding to the second tooth plate 42 on the other side of the base member 4 in the transverse direction (left side in this embodiment).

Figure 5 Figure 5

[0053] In this embodiment, the dam bottom structure 1 transmits and diffuses the upper load and external force through the tooth plates 42, and the front tenon 43 and the front mortise 44 of one of the base members 4 are connected to the rear mortise 45 and the rear tenon 46 of the other base member 4, respectively, to form a whole, which improves the overall stability of the dam foundation and reduces uneven settlement.​​​

[0054] like Figures 6-8 As shown, the dam structure 2 includes multiple herringbone components 5 with a cross-section in the shape of a herringbone. The multiple herringbone components 5 are connected longitudinally in rows, and the multiple rows of herringbone components 5 are arranged laterally in layers. Between each two adjacent rows of herringbone components 5 in each layer, the rows of herringbone components 5 of the upper layer are arranged. The number of rows of herringbone components 5 in each layer of the dam structure 2 gradually decreases upward (the number of rows in the upper layer of two adjacent layers of herringbone components is 1 less than the number of rows in the lower layer), forming a pyramid shape, and the top layer has at least two rows of herringbone components 5. The dam structure 2 contains at least three layers of herringbone components 5.

[0055] Each herringbone component 5 includes a central hexagonal prism 51 with its edges arranged longitudinally, and three secondary branches 52 extending outward from the three spaced sides of the central prism 51. Each secondary branch 52 has a water-permeable hole 53, and the included angle between adjacent secondary branches 52 is 120°. The three secondary branches 52 are all cuboids of the same shape, with the length of the edge on the side of the connecting central prism 51 as the length direction, the side length as the thickness direction, and the extension direction of the secondary branch 52 as the width direction. The water-permeable hole 53 is located at the centroid of the length and width of the secondary branch 52 and extends through it in the thickness direction. In some preferred embodiments, the diameter of the water-permeable hole 53 does not exceed 1 / 2 of the width of the secondary branch 52.

[0056] Of the three secondary branches 52, the one extending vertically upward is the top secondary branch 521, and the other two secondary branches 52 are the bottom secondary branches 522. The central axis branch 51 forms a central support surface 54 on the side between the top secondary branch 521 and each of the bottom secondary branches 522, and forms a bottom support surface 55 on the side between the two bottom secondary branches 522.

[0057] In this embodiment, the bottom row of herringbone members 5 is correspondingly disposed between each pair of adjacent toothed plates 42, and the two bottom secondary branches 522 end faces of each bottom herringbone member 5 are correspondingly fitted and connected to the lateral side faces of the adjacent toothed plates 42. The two bottom secondary branches 522 end faces of each layer of herringbone members 5 are correspondingly fitted and connected to the middle support surface 54 of the adjacent herringbone member 5 in the next layer, and the bottom support surface 55 of each layer of herringbone members 5 are correspondingly fitted and connected to the top secondary branches 521 end faces of the two layers of herringbone members 5 below. The multi-layer herringbone members 5 form a stable honeycomb-like structure, improving force transmission, enhancing the stability of the dam structure 2, and increasing the strength and stiffness of the dam structure 2.

[0058] The dam body structure 2 is assembled by the plurality of herringbone components 5 into a plurality of layers and rows of internal honeycomb channels 7, greatly saving the material of the dam body, reducing the weight of the dam body and the stress on the foundation, and reducing the settlement amount. The internal honeycomb channels 7 are longitudinally formed between the herringbone components 5, between the herringbone components 5 and the base components 4, and between the herringbone components 5 and the cover components 6, and are communicated by the water permeable holes 53. In the embodiment, the internal honeycomb channels 7 include: first honeycomb channels 71 with a trapezoidal cross section formed between the bottom plate 41 on the base component 4 and the herringbone component 5 above; second honeycomb channels 72 with a hexagonal cross section formed between the tooth plate 42 on the base component 4 and the herringbone component 5 above; third honeycomb channels 73 with a triangular cross section formed between the herringbone components 5; and fourth honeycomb channels 74 formed between the cover component 6 and the herringbone component 5 below.

[0059] As shown in Figure 2 The first honeycomb channel 71 is formed by the bottom plate 41 and the bottom support surface 55 and the two bottom branches 522 of the herringbone component 5 directly above; the second honeycomb channel 72 is formed by the tooth plate 42 and the bottom branches 522 of the herringbone components 5 on both sides and the two bottom branches 522 and the bottom support surface 55 of the herringbone component 5 directly above; the third honeycomb channel 73 is formed by the branches 52 of the three herringbone components 5; and the fourth honeycomb channel 74 is formed by the panel 61 and the herringbone component 5 below. The first honeycomb channel 71, the second honeycomb channel 72, the third honeycomb channel 73, and the fourth honeycomb channel 74 are communicated by the water permeable holes 53, and each honeycomb channel 72 makes the dam body structure 2 have a honeycomb shape in the cross section.

[0060] In the embodiment, the water permeable holes 53 of the herringbone components 5 on both sides of the dam body reduce the effect of waves and external forces, slow down the flow rate of water flowing into the dam body and the turbulence of the dam body, and promote the exchange of aquatic organisms inside and outside the dam body; the water permeable holes 53 of the herringbone components 5 communicate the internal honeycomb channels 7 of each layer and each row inside the dam body, promote the mutual exchange of water and aquatic organisms inside the dam body, and provide a variety of habitats for various aquatic organisms, such as hiding, growing, spawning, and playing in water.

[0061] In the embodiment, the water permeability of the dam body can be controlled by the size of the water permeable holes 53, achieving the purpose of controlling the flow rate and cross-sectional flow of the engineering area, the height of the upstream water level of the dam body, and adjusting the water surface gradient.

[0062] In the embodiment, the number of layers of the herringbone components 5 on the cross section of the dam body structure is one less than the number of layers of the herringbone components 5 below, and the plurality of layers are assembled in a pyramid shape in the cross section, so that the herringbone components 5 are engaged layer by layer, greatly improving the overall stability and anti-overturning performance of the assembled dam body; when the herringbone components 5 are stacked in multiple layers, the through transverse seams are avoided in the cross section.

[0063] As shown in the drawings, the dam top structure 3 comprises a plurality of cover plate members 6 arranged longitudinally, the cover plate member 6 comprising a panel 61 and a side plate 62 arranged downward on both sides of the panel 61, the panel 61 being arranged directly above the top layer of the herringbone member 5 and the side plate 62 being arranged in close contact with the lateral side of the top layer of the herringbone member 5. Figures 9-11

[0064] In this embodiment, the cover plate member 6 limits the top secondary branch 521 of the two herringbone members 5 at the top by the side plates 62 on both sides, thereby improving the stability and flatness of the dam top and forming a whole dam top, which is convenient for daily inspection by maintenance personnel.

[0065] In this embodiment, each unit member (the base member 4, the herringbone member 5, and the cover plate member 6) can be prefabricated in the factory and assembled on site, which can greatly shorten the on-site construction period, alleviate the restriction of the construction by the source of sand and stone materials and the surrounding environment, and relieve the contradiction between construction and navigation, improve the prefabrication and on-site construction quality, and realize fine management and green construction.

[0066] The working principle of this embodiment is as follows:

The dam body structure is assembled by the herringbone members composed of the central axis branch 51 of the regular hexagonal prism and the three secondary branches 52 arranged uniformly around the central axis branch; the two bottom secondary branches 522 at the lower end of the upper layer of the herringbone member are supported by the central axis branch on both sides of the lower layer of the herringbone member, and the top secondary branch 521 at the upper end of the lower layer of the herringbone member supports the bottom of the central axis branch of the upper layer of the herringbone member, so that the members are engaged layer by layer, and the multi-layer assembly presents a pyramid shape in the cross section, forming a stable honeycomb-like structure; the dam body structure is assembled by multiple herringbone members into multiple layers and multiple rows of internal honeycomb channels 7; the water permeable holes of the herringbone members reduce the effect of waves and external forces and slow down the flow rate of the water flow entering the dam body and the turbulence of the dam body; the water permeable holes connect the internal honeycomb channels 7 of each layer and each row in the dam body. The dam top structure is assembled by the side plates of the cover plate member clamping the secondary branches at the upper end of the top layer of the herringbone member of the dam body, and the dam top forms a whole.

[0068] The water permeability involved in this embodiment can be controlled by the size of the water permeable hole, so as to control the flow rate and cross-sectional flow of the engineering area, control the backwater height of the upstream water level of the dam body, and adjust the water surface gradient.
