Description

Technical Field

[0001] This invention belongs to the field of landscape engineering restoration technology, specifically relating to a landscape engineering restoration structure and its restoration method. Background Technology

[0002] The Integrated Protection and Restoration Project of Mountains, Rivers, Forests, Farmlands, Lakes, Grasslands, and Deserts (hereinafter referred to as the "Mountain and River Project") is a major strategy in my country's ecological governance field. Its core concept is to achieve the synergistic optimization of natural ecological space and human activity space through systematic and holistic means. Wetlands, as the core carrier of the "water" element in the Mountain and River Project, undertake key functions such as water conservation, runoff regulation, and biodiversity maintenance. Due to their special water-land intertwining characteristics, wetland shallow areas are not only ecologically sensitive areas but also key nodes in the coordinated governance of "water and land" in the Mountain and River Project.

[0003] In recent years, the dynamic hydrological regulation of wetland shoals has become increasingly prominent during the implementation of water conservancy projects. Affected by global climate change, extreme rainfall events occur frequently, leading to a surge in runoff in wetland catchment areas during rainy seasons or heavy rainfall. Shallow areas are often submerged due to short-term water level rises, causing damage to the ecology of the shoal areas. For example, long-term submersion causes the death of vegetation (such as reeds and cattails) in the shoal areas due to lack of oxygen, and the loss of benthic organism habitats; water erosion exacerbates the loss of surface soil and nutrients in the shoals, and damages the micro-topographic structure of the wetlands.

[0004] In view of this, the inventor conducted in-depth research on the aforementioned deficiencies in the prior art, which led to the creation of this case. Utility Model Content

[0005] The purpose of this invention is to provide a landscape engineering restoration structure and its restoration method, which can adaptively adjust the amount of water entering the wetland to prevent the shallow water area from being flooded or the soil from being lost during the rainy season, thus avoiding damage to the ecology of the shallow water area.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0007] A landscape restoration structure includes a drainage ditch built along the periphery of a wetland and a reservoir located at the inlet of the drainage ditch. The inlet of the drainage ditch is equipped with a diversion channel that draws water from the reservoir into the wetland. The diversion channel passes through the drainage ditch and cuts it off. A flow control component is installed within the diversion channel. This component includes side baffles located on both sides of the diversion channel and blocking the drainage ditch, a front baffle located at the outlet of the diversion channel and capable of blocking the channel, and buoys that control the up-and-down movement of the side baffles and the front baffles. The front baffle and the side baffles can move up and down synchronously. The reservoir has an outlet communicating with the diversion channel. The buoys are located within the reservoir and are connected to the front baffles and side baffles via connecting frames.

[0008] Furthermore, the front baffle has a lower water-blocking section and an upper water-passing section. The water-blocking section is located below the side baffle, and the water-passing section has a plurality of fences formed on it. By setting fences on the water-passing section, the water flowing into the wetland can be filtered, preventing large dead branches, driftwood, or man-made debris from entering the wetland.

[0009] Furthermore, it also includes a receiving trough constructed within the wetland and near the outlet of the drainage channel, into which the water-blocking part of the front baffle can extend. The receiving trough provides better protection for the water-blocking part, preventing the soil in the wetland from adhering to it.

[0010] Furthermore, the buoy has a bag-like structure, with a protective net around its outer perimeter. The top and bottom of the buoy are equipped with insert sleeves, and the protective net contains insert posts that mate with these sleeves. The protective net protects the buoy from being punctured by floating debris.

[0011] Furthermore, the connecting frame includes a connecting plate, multiple connecting columns fixedly connected to the top of the connecting plate, a connecting frame fixedly connected to the top of the multiple connecting columns, and a bracket connecting the connecting frame to the top of the protective net. The connecting plate is fixedly connected to the side baffles on both sides near the side baffles and to the front baffle on the side near the front baffle. The connecting frame allows for better simultaneous connection of the side baffles and the front baffles to the buoy, enabling them to move up and down simultaneously under the influence of the buoy.

[0012] Furthermore, a shock absorber is also provided between the support frame and the protective net. The shock absorber allows the buoy to adapt to the up-and-down movement of the buoy caused by the waves in the reservoir.

[0013] Furthermore, the height of the water inlet is equal to or higher than the height of the drainage channel.

[0014] A method for restoring landscape engineering includes the following steps:

[0015] S1: Construct drainage ditches along the perimeter of the wetland and open diversion channels at the inlet of the drainage ditches;

[0016] S2: Construct a water storage tank, which is located at the inlet end of the drainage ditch;

[0017] The water flow control component is then installed on the diversion channel.

[0018] Furthermore, the width of the drainage ditch is 60cm-100cm, and the depth of the drainage ditch is 60cm-100cm.

[0019] Furthermore, the depth of the water storage tank is 200cm-250cm.

[0020] With the above structure, the landscape engineering restoration structure and restoration method of the present invention, compared with the prior art, by constructing a drainage ditch along the periphery of the wetland and a reservoir at the inlet of the drainage ditch, and opening a diversion channel at the inlet of the drainage ditch connecting the reservoir and the interior of the wetland, and by setting a water flow control component in the diversion channel, the water flowing into the reservoir can flow normally into the wetland under normal conditions, ensuring the normal water volume required by the wetland. During the rainy season or rainy season, the rainwater can be diverted downstream of the wetland through the drainage ditch by the water flow control component, so as to avoid damage to the ecology of the shallow beach area in the wetland.

Detailed Implementation

[0027] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. Furthermore, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0028] like Figures 1-4As shown, this invention relates to a landscape engineering restoration structure, comprising a drainage ditch 1 constructed along the periphery of a wetland and a reservoir 2 located at the inlet end of the drainage ditch 1. The reservoir 2 collects the water expected to flow into the wetland. The outlet end of the drainage ditch 1 is located downstream of the wetland. The inlet end of the drainage ditch 1 is equipped with a diversion channel 11 that guides water from the reservoir 2 into the wetland. The diversion channel 11 passes through the drainage ditch 1 and cuts it off. Through the inlet and outlet ends, the wetland can still maintain connectivity with the outside world, preventing the degradation of the wetland's ecosystem. Structurally, the drainage ditch 1 semi-encloses the wetland, with the inlet end located upstream and the outlet end located downstream. Downstream of the wetland, a water flow control component 3 is installed in the diversion channel 11. The water flow control component 3 includes side baffles 31 located on both sides of the diversion channel 11 and blocking the drainage channel 1, a front baffle 32 located at the outlet of the diversion channel 11 and blocking the diversion channel 11, and a buoy 33 that controls the up and down movement of the side baffles 31 and the front baffle 32. The front baffle and the side baffles 31 can move up and down synchronously. The water storage tank 2 has a water outlet 21 that communicates with the diversion channel 11. The height of the water outlet 21 is equal to or higher than the height of the diversion channel 11. The buoy 33 is located in the water storage tank 2. The buoy 33 is connected to the front baffle 32 and the side baffle 31 through a connecting frame 34. During heavy rains or rainy seasons, when the water flow increases suddenly, the water level in the reservoir 2 rises, causing the buoy 33 to float upwards. Under the action of the buoy 33, the side baffle 31 and the front baffle 32 rise further, thereby closing the outlet of the diversion channel 11 and connecting the drainage ditch 1 and the reservoir 2. This allows the water to be discharged from the drainage ditch 1 along the periphery of the wetland to the downstream of the wetland, thus preventing the shallow areas within the wetland from being flooded or the soil from being eroded.

[0029] In this embodiment, the front baffle 32 has a lower water-blocking part 321 and an upper water-passing part 322. The water-blocking part 321 is located below the side baffle 31, and the water-passing part 322 is flush with the side baffle 31. To prevent large dead branches, driftwood, or man-made debris from entering the wetland and damaging its ecological environment, several fences 3221 are formed on the water-passing part 322. These fences 3221 can trap large debris, which can then be removed during subsequent patrols.

[0030] In this embodiment, since the water-blocking part 321 of the front baffle 32 is normally located below the drainage channel 11, it may sink into the soil of the wetland and be absorbed by the soil if it remains stationary for a long time. Therefore, a receiving trough 4 is constructed in the wetland near the outlet of the drainage channel 11. The receiving trough 4 is a concrete structure, and the water-blocking part 321 of the front baffle 32 can extend into the receiving trough 4. The receiving trough 4 can better protect the water-blocking part 321 and prevent the soil in the wetland from absorbing the water-blocking part 321.

[0031] In this embodiment, the buoy 33 has a bag-like structure, and a protective net 35 is provided around the outer periphery of the buoy 33. The protective net 35 is made of metal, such as wire mesh. The top and bottom of the buoy 33 are provided with insertion sleeves 331, and the protective net 35 is provided with insertion posts 351 that cooperate with the insertion sleeves 331. The protective net 35 can protect the buoy 33 and prevent floating objects in the water from puncturing the buoy 33.

[0032] In this embodiment, the connecting frame 34 includes a connecting plate 341, multiple connecting columns 342 fixedly connected to the top of the connecting plate 341, a connecting frame 343 fixedly connected to the top of the multiple connecting columns 342, and a bracket 344 connecting the connecting frame 343 and the top of the protective net 35. The two sides of the connecting plate 341 near the side baffle 31 are fixedly connected to the side baffle 31, and the side near the front baffle 32 is fixedly connected to the front baffle 32. The connecting frame 34 can better connect the side baffle 31 and the front baffle 32 to the buoy 33 at the same time, so that the side baffle 31 and the front baffle 32 can move up and down simultaneously under the action of the buoy 33.

[0033] In this embodiment, a shock absorber 36 is also provided between the support 344 and the protective net 35. The shock absorber 36 can make the buoy 33 adapt to the up and down movement of the buoy 33 caused by the waves in the water storage tank 2, and prevent the front baffle 32 and the side baffle 31 from moving up and down at the same time due to the normal range of the buoy 33's movement.

[0034] This invention also relates to a method for restoring landscape engineering, comprising the following steps:

[0035] S1: Construct a drainage ditch 1 along the perimeter of the wetland, and open a diversion channel 11 at the inlet end of the drainage ditch 1.

[0036] S2: Construct a water storage tank 2, which is located at the inlet end of the drainage ditch 1.

[0037] S3: Assemble the water flow control component 3 and install the water flow control component 3 on the diversion channel 11.

[0038] Specifically, both drainage ditch 1 and water storage tank 2 are concrete structures. The width of drainage ditch 1 is 60cm-100cm and the depth of drainage ditch 1 is 60cm-100cm. The depth of water storage tank 2 is 200cm-250cm. The width of diversion channel 11 is 60cm-80cm and the depth is the same as that of drainage ditch 1. In addition, drainage ditch 1 is sloping, with the inlet end of drainage ditch 1 being higher than the outlet end.

[0039] The above provides a detailed description of a landscape engineering restoration structure provided by the present invention. The specific embodiments are described only to aid in understanding the method and core ideas of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
