[0001] The utility model relates to a dam, in particular to a reinforced waterproof and drainage combined dam body. Background Art

[0002] Earth-rock dam refers to a water retaining dam built by dumping, rolling and other methods with local soil, stone or mixed materials. In order to improve the stability of the dam body, the reinforced earth-rock dam body of traditional water storage and landfill uses reinforcement technology to set up clay sacks stacked up and down at the slope of the slope, and the sacks are wrapped with geogrids to form a well-integrated retaining structure. At the same time, a drainage hole anti-filtration layer is set behind the sacks to play a drainage role. However, in the flood season or the dam body water storage period, the water content in the earth-rock dam body will increase rapidly in a short period of time. The drainage hole anti-filtration layer behind the sacks can only sporadically remove the water that flows into the anti-filtration layer in a small area around it, and cannot play the role of collecting and discharging large-scale water in the entire dam body. If the dam body contains excessive water for a long time, it will cause the dam body to become unstable and collapse, causing serious casualties, property losses and pollution of the surrounding environment.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the utility model.

[0028] A reinforced waterproof and drainage combined dam body according to an embodiment of the utility model, such as Figures 1 to 4 As shown, the dam body includes a stepped clay assembly 10, a sack bag 20, a waterproof clay layer 30, and a slope clay layer 40, wherein:

[0029] The stepped clay assembly 10 is composed of several layers of reinforced clay layers arranged in a stepped manner; the stepped clay assembly 10 serves as the main body of the dam body, and its stepped multi-level platform structure design can effectively alleviate the influx speed of water flow and reduce the impact force of water flow on the dam body; the reinforced clay layer can enhance the bearing capacity and stability of the dam body, prevent the dam body from settling, and improve the safety and service life of the dam structure.

[0030] The sacks include gravel sacks 201 and spillway filter bags 202; two layers of sacks 20 stacked up and down are arranged on the outside of each reinforced clay layer; the spillway filter bags 202 are dispersed between the gravel sacks 201; the sacks 20 can interact with each other to form a dynamic water collection bar. When the dam body accumulates water, the water flow is collected in time through the water collection bar, and then flows into the spillway filter bag 202 and then discharged from the dam body, thus forming a drainage system; in the face of flood season or dam body water storage period, the drainage body The system can discharge excess water in time, improve the drainage efficiency of the dam body, avoid excessive water accumulation inside the dam body, and reduce potential dangers caused by excessive water accumulation in the dam body, such as softening, expansion and deformation of the foundation caused by rising water levels, and even instability and collapse of the dam body; the combination of the gravel sack bag 201 and the spillway filter bag 202 realizes the drainage function, reduces the construction procedures, improves the construction efficiency, reflects the advancement and practicality of engineering technology, and is of great significance to improving the quality and safety of the project.

[0031] A waterproof clay layer 30 formed by smoothing clay is provided on the top of the stepped clay assembly 10. The waterproof clay layer 30 is provided on the top of the stepped clay assembly 10 by utilizing the water absorption and plasticity of clay. When the clay encounters water, it absorbs water and expands, filling the pores of the soil body to form a dense penetration barrier layer, thereby playing a role in waterproofing and anti-seepage, effectively preventing the penetration of water and enhancing the safety of the dam body.

[0032] The outer side of the gunny bag 20 is provided with a slope clay layer 40 which is smoothed with clay to form an inclined surface, which can prevent the sliding and collapse of the slope and ensure the stability of the dam body.

[0033] Specifically, Figures 2 to 4As shown, each reinforced clay layer includes a geogrid 50 and a connecting rod 60. Geogrids 50 are provided on the upper and lower surfaces of the reinforced clay layer. The geogrid 50 on the lower surface is folded back and connected to the geogrid 50 on the upper surface through the connecting rod 60. The geogrid 50 has good flexibility and high strength. The upper and lower geogrids 50 are folded back to wrap the reinforced clay layer. This structure not only effectively supports and fixes the reinforced clay layer, but also reduces the sliding and deformation of the reinforced clay layer when subjected to external forces due to the high strength characteristics of the geogrid 50 itself, thereby enhancing the overall bearing capacity of the dam body. The geogrid can also effectively block the transmission of seismic force, improve the seismic performance of the dam body, strengthen the stability of the dam body, and ensure that the dam body can maintain a stable state when facing sudden earthquakes.

[0034] Specifically, Figures 2 to 4 As shown, the civil engineering grids 50 of the upper and lower reinforced clay layers are in contact and fixed as a whole. This structural design not only enhances the stability and durability of the reinforced clay layers, but also, through the fixation of the civil engineering grids 50, enables the reinforced clay layers to fit closely together, further enhancing the bonding force between the soil layers.

[0035] Specifically, Figures 2 to 4 As shown, the dam body also includes slope spraying grass 70, which is located on the surface of the slope clay layer 40. By introducing vegetation to the slope surface, a biological barrier can be formed to enhance the stability of the slope, reduce the impact of water flow on the slope clay layer 40, and also reduce the erosion of the slope clay layer 40 by wind, thereby preventing soil erosion; in addition, grass planting not only helps to maintain soil moisture and nutrients, but also conserves water resources, improves the ecological environment of the slope, increases the vegetation coverage of the slope, and enhances the ecological function of the slope.

[0036] Specifically, Figure 5 to Figure 6 As shown, the gravel sack 201 includes a first sack 2011 and a first gravel layer 2012, and the first sack 2011 is filled with the first gravel layer 2012. When selecting the first sack 2011, a material with good durability and strong toughness should be selected to ensure the firmness and durability of the dam structure; the gravel should be hard and not easy to break stones to strengthen the stability of the dam body; the gravel sack 201 is used to replace the traditional clay sack, and water collection bars can be formed between the gravel sacks 201. When the dam accumulates water, the water flow can be timely collected through the water collection bars to speed up the drainage.

[0037] Specifically, Figure 6As shown, the drain pipe filter bag 202 includes a second sack 2021, a second gravel layer 2022, a stone chip layer 2023 and a PVC pipe 2024. The second sack 2021 is wrapped in the outer layer of the stone chip layer 2023, and the stone chip layer 2023 is wrapped in the outer layer of the second gravel layer 2022. One end of the PVC pipe 2024 is inserted into the second gravel layer 2022, and the other end extends to the outside of the slope clay layer 40. After being collected by the water confluence bar, the water flows to the drain pipe filter bag 202, flows to the outside of the slope clay layer 40 through the PVC pipe 2024, and is discharged from the dam body to achieve the effect of drainage. The discharged water is used to irrigate the vegetation on the slope to achieve the rational use of water resources.

[0038] Specifically, Figure 6 As shown, the diameter of the PVC tube 2024 is 8 cm to 12 cm. Preferably, the PVC tube 2024 with a diameter of 10 cm is selected.

[0039] Specifically, Figure 1 As shown, the spacing between adjacent drain pipe filter bags 202 is 1.5m to 2.5m. Preferably, the spacing between adjacent drain pipe filter bags 202 is 2m.

[0040] Specifically, Figure 1 As shown, the drain pipe filter bag 202 is dispersed in the gravel sack bag 201 in a plum blossom shape. The plum blossom shape distribution means that a number of sack bags 20 form a rectangle. There are a number of rectangles in total. The intersection of the two diagonals of each rectangle is the center point. The drain pipe filter bag 202 is distributed at the four end points and the center point of the rectangle. The distances from the four end points to the center point are equal. The plum blossom shape uniform distribution of the drain pipe filter bag 202 can better achieve the drainage effect and improve the drainage efficiency.
