Those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.

[0028] Refer to Figures 1-4, the first embodiment of the present utility model, an ecological water box system, which includes a water box main body 10, an inlet ditch 21 and an outlet ditch 22. The water box main body 10 includes an enclosing body 11. An inner side of the enclosing body 11 is enclosed to form a water box cavity 12. The enclosing body 11 includes a rammed soil layer 111, a geomembrane layer 112 and a first hollow brick layer 113 laid in sequence from bottom to top. An inner cavity of the first hollow brick layer 113 is filled with planting soil for planting plants. The inlet ditch 21 is arranged on one side of the water box main body 10 and communicates with the water box cavity 12. The outlet ditch 22 is arranged on the other side of the water box main body 10 and communicates with the water box cavity 12. Wherein, the depth of the water box cavity 12 is H, and the longitudinal projection width is W, 1.2m ≤ H ≤ 1.8m, 3.5m ≤ W ≤ 5m. The first hollow brick layer 113 includes a plurality of first hollow brick bodies 1131 arranged in a honeycomb shape and in a hexagonal shape.

[0029] Taking the implementation and construction of this ecological water box system on a slope as an example, first, a vacant land is arranged on the slope, and then a foundation pit is excavated; after excavation, the bottom of the foundation pit is first rammed, and then the side slope of the side wall of the foundation pit is rammed in layers. The layer height is 0.15 - 0.25m to ensure the density and flatness of ramming. The water content of the rammed soil is not greater than 20% to ensure that the geomembrane will not be damaged. After ramming, a rammed soil layer 111 is formed; a geomembrane is laid on the surface of the rammed soil layer 111; the first hollow brick bodies 1131 are laid on the geomembrane to form the first hollow brick layer 113, and mortar is used for masonry and caulking between the first hollow brick bodies 1131; planting soil is filled inside the first hollow brick bodies 1131, and grass seeds are sown using the planting soil. After the grass seeds germinate and grow, vegetation is formed. In addition, the inlet ditch 21 and the outlet ditch 22 are in the form of excavated soil ditches. The soil ditches are appropriately rammed, and grass seeds can be sown in the inlet ditch 21 and the outlet ditch 22 to form vegetation.

[0030] In this embodiment, the longitudinal section of the water box cavity 12 is in an inverted trapezoid shape, and the bottom width of the water box cavity 12 is W1, 0.8m ≤ W1 ≤ 1.2m, so as to form a side slope of the water box cavity 12 with a moderate slope to ensure the stability of the water box main body 10.

[0031] In this embodiment, the enclosing body 11 extends horizontally along the outer side of the top of the water box cavity 12 to form an annular edge 114. The cross-sectional width of the edge 114 is W2, 0.4m ≤ W2 ≤ 0.6m. Through the extended protection of the edge 114, water erosion into the lower part of the water box cavity 12 is reduced to ensure the stability of the water box main body 10.

[0032] Refer to Figures 5-7 , the second embodiment of the present utility model. Compared with the first embodiment, in this embodiment: a filtering and sedimentation structure 30, a water diversion ditch 23, an anti-erosion structure 40, etc. are also provided.

[0033] Specifically, the bottom surface of the water inlet ditch 21 is recessed to form a first settling tank 211, and the filtering and settling structure 30 is arranged in the first settling tank 211. Among them, the filtering and settling structure 30 includes a first soil cushion layer 31, a first mortar cushion layer 32, a first bricklaying layer 33 and an orifice plate 34. The first soil cushion layer 31 is arranged on the bottom surface of the first settling tank 211, the first mortar cushion layer 32 is arranged on the top surface of the first soil cushion layer 31, the first bricklaying layer 33 is laid on the top surface of the first mortar cushion layer 32 and the side wall of the first settling tank 211, and the first bricklaying layer 33 extends upward and is laid on the side wall of the water inlet ditch 21. The orifice plate 34 is arranged in the first settling tank 211, and the orifice plate 34 is located inside the first bricklaying layer 33. The orifice plate 34 is formed with a plurality of vertically arranged filtering plate parts 341 and two mounting plate parts 342 by means of bending processing. The two mounting plate parts 342 are located on the side of the filtering plate parts 341 away from the water box cavity 12. The height of the plurality of filtering plate parts 341 increases along the water inlet direction. Both of the two mounting plate parts 342 are provided with through openings 3421, and a second hollow brick 35 is stacked between the two mounting plate parts 342. Among them, the hole width of the second hollow brick 35 is larger than the hole width of the orifice plate 34, and the holes of the second hollow brick 35 are parallel to the water flow direction.

[0034] During construction, soil is used to tamp in the first settling tank 211 to form the first soil cushion layer 31, and then mortar is laid to form the first mortar cushion layer 32 to form a stable foundation to ensure the stability of the entire filtering and settling structure 30. The bricks of the first bricklaying layer 33 are connected by mortar masonry, and a waterproof mortar layer is covered on the surface of the bricks to reduce water penetration. The water inlet ditch 21 is mostly in a dry state and usually only has water flowing when there is more surface precipitation.

[0035] When there is surface precipitation, water converges and flows in the water inlet ditch 21. The water flow first passes through the second hollow brick 35, and the water flow is filtered through the second hollow brick 35 to intercept larger stones, branches and other sundries, as well as part of the sediment. The water flow can be filtered through the filtering plate parts 341 to intercept smaller stones and other sundries and filter and intercept the sediment, so that the sediment is intercepted and settled on the orifice plate 34. In this way, the filtering and settling structure 30 can intercept stones and other sundries and intercept and settle part of the sediment, reduce the stones, sediment, etc. discharged into the water box cavity 12, thereby alleviating the siltation of the water box cavity, reducing the frequency of maintenance and dredging of the water box system, and reducing the maintenance cost. In addition, after the second hollow brick 35 and the orifice plate 34 are taken out respectively, they can be cleaned. The orifice plate 34 and a single second hollow brick 35 are of low weight and are convenient to take and place, making the filtering and settling structure 30 convenient to maintain and with low maintenance workload.

[0036] Among them, referring to Figure 6 , the first bricklaying layer 33 also extends and is embedded in the bottom surface of the water inlet ditch 21 at both ends of the first settling tank 211 to prevent the water flow from directly impacting and eroding the side wall of the first settling tank 211.

[0037] The water diversion ditch 23 can be arranged along the slope surface of the sloping land so that when there is surface precipitation, the flowing water on the slope surface can be guided into the water inlet ditch 21 through the water diversion ditch 23. Among them, the end of the water diversion ditch 23 is communicated with one side wall of the water inlet ditch 21, and an anti-erosion structure 40 opposite to the end of the water diversion ditch 23 is arranged on the other side wall of the water inlet ditch 21.

[0038] Specifically, the bottom surface of the water inlet ditch 21 is recessed to form a second sink 212. The anti-erosion structure 40 includes a second cushion layer 41, a second mortar layer and a second bricklaying layer 43. The second cushion layer 41 is arranged on the bottom surface of the second sink 212, the second mortar layer is arranged on the top surface of the second cushion layer 41, the second bricklaying layer 43 is laid on the top surface of the second mortar layer, and the second bricklaying layer 43 extends and is embedded in the other side wall of the water inlet ditch 21. Among them, the second cushion layer 41 is formed by ramming soil in the second sink 212, and then a second mortar cushion layer 42 is laid to form a stable foundation to support the second bricklaying layer 43. The second bricklaying layer 43 does not protrude from the inner surface of the water inlet ditch 21, and the bricks of the second bricklaying layer 43 are connected by mortar masonry, and a waterproof mortar layer is covered on the surface of the second bricklaying layer 43. The water discharged from the end of the water diversion ditch 23 impacts on the anti-erosion structure 40, which can prevent the water flow from directly impacting the surface of the water inlet ditch 21 and causing erosion.

[0039] In summary, the patent solution combines the natural water pit with the traditional reservoir technology for the purpose of anti-seepage, water storage and cost saving. First, the volume is adjusted from a pool to a pond, reducing the land occupation and making the site selection more flexible, especially more applicable in some areas with narrow and small fields; second, the method of using geomembrane for anti-seepage + fixing with hexagonal hollow bricks not only realizes the purpose of water storage but also reduces the material consumption. Compared with the traditional reinforced concrete reservoir, the materials used are simpler and the price is cheaper; at the same time, grass is planted inside the hollow bricks, making it economical, environmentally friendly and able to be organically combined with the surrounding environment, natural and beautiful; third, the hexagonal hollow bricks are mainly constructed by the jigsaw process, which is more convenient for construction and more convenient for later maintenance and replacement.

[0040] The above has described the embodiments of the present invention in detail with reference to the drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the knowledge scope of those of ordinary skill in the art.
