A submerged area vegetation in-situ protection and waterlogging prevention structure

Abstract

The application discloses a kind of submerged area vegetation in-situ protection and anti-flood structure, which is surrounded by arranging protection structure and anti-seepage structure in submerged area to form in-situ protection area, to solve the problem of vegetation, especially valuable tree species, being submerged; and drainage structure is arranged in the protection area to solve the problem of valuable vegetation, especially valuable tree species, being waterlogged. Due to the difference in vegetation varieties, habitat and habits, the underground saturated water level depth required to maintain the healthy growth of the vegetation is also different. To ensure that the underground water level depth is within the range suitable for the growth of trees, drainage structure is also provided in the vegetation growth area, and underground water level monitoring measures are provided. The underground water level depth is h (distance from the ground surface). When the underground water level is monitored to be less than h, the underground water level is lowered through the drainage structure so that the underground water level height does not exceed h, preventing submersion and ensuring the healthy growth of valuable tree species of various varieties.

Description

[Technical Field]

[0001] This utility model belongs to the field of water conservancy and hydropower engineering technology, specifically relating to an in-situ protection and flood control structure for vegetation in flooded areas, and in particular, a protective structure for the in-situ protection of precious tree species in flooded areas. [Background Technology]

[0002] Greening refers to the planting of protective forests, roadside trees, crops, and various plants in residential areas and parks. Greening includes national land greening, urban greening, roadside greening, and roadside greening. It plays multiple roles in improving environmental sanitation and maintaining ecological balance. In some areas, such as scenic spots, parks, and tourist attractions, valuable tree species are planted to enhance their aesthetic appeal. These areas are regularly maintained, thus providing better protection for these valuable trees. However, due to the high cost and difficulty of transplanting some valuable tree species, the risk of transplanting is high. To protect these precious resources and create a good ecological environment, in the absence of transplanting conditions, it is necessary to protect valuable tree species in situ within the flooded area.

[0003] Flooded areas often submerge all vegetation below the waterline. To protect the ecological environment and maintain biodiversity, it is necessary to protect the trees involved in the flooding. Most of these trees are relocated, while a few valuable tree species that pose a greater risk of transplantation require in-situ protection. Furthermore, different species of valuable trees require different groundwater levels for healthy growth, necessitating different protection methods, which increases the difficulty of conservation.

[0004] In view of this, the present invention provides an in-situ protection and flood prevention structure for valuable tree species in flooded areas, thereby preventing the trees in the flooded area from being submerged. [Summary of the Invention]

[0005] To address the aforementioned problems, this utility model provides an in-situ protection and flood control structure for vegetation in flooded areas. This structure can protect vegetation in flooded areas in situ, preventing the occurrence of situations such as the submersion of valuable tree species within the flooded area.

[0006] This utility model is achieved through the following technical solution, providing a structure for in-situ protection of vegetation and flood control in flooded areas, including:

[0007] A protective structure located on the water-facing side for raising the water level of the flooded area includes: a water-facing surface, a dike top, and a backwater surface. The water-facing surface, the dike top, the backwater surface, and the original ground line form a trapezoidal space, and the trapezoidal space is filled with material to form the dike body.

[0008] The first seepage prevention structure is vertically installed between the original ground line and the top of the dike, and its lower part extends below the original ground line;

[0009] A second seepage-proof structure is vertically installed on the other side of the original ground line, extending below the original ground line, and the second seepage-proof structure and the first seepage-proof structure are located on both sides of the vegetation to be protected;

[0010] A drainage structure located at a low point in the in-situ protection zone includes: a seepage well, a pumping device, and an outlet pipe. The seepage well is located at a low point in the in-situ protection zone, the pumping device is located inside the seepage well, and one end of the outlet pipe is connected to the pumping device, while the other end is distributed along the original ground line, the back water surface, the top of the embankment, and the front water surface to discharge the water in the seepage well.

[0011] The monitoring equipment used to monitor whether the groundwater level is higher than the groundwater height required for the protection of vegetation is installed on the side of the vegetation facing the protective structure.

[0012] A controller used to determine whether to activate a pumping unit based on the groundwater level monitored by the monitoring equipment.

[0013] Specifically, the material of the embankment is any one of soil, stone, concrete, reinforced concrete, or a mixture of soil and stone.

[0014] Specifically, the seepage prevention structure adopts a combination of earth-rock core wall and suspended seepage prevention wall, or earth-rock embankment combined with seepage prevention wall and foundation curtain grouting, or reinforced concrete embankment combined with curtain grouting.

[0015] Specifically, the pumping device is any one of a submersible pump, a centrifugal pump, or a long-shaft submersible pump.

[0016] Compared to existing designs, this invention provides an in-situ protection and flood control structure for vegetation in flooded areas. It addresses the problem of vegetation (especially valuable tree species) being submerged by establishing protective and seepage-proof structures within the flooded area. Simultaneously, this invention incorporates drainage structures within the protected area to prevent waterlogging of the vegetation (especially valuable tree species). Furthermore, different vegetation species require different groundwater depths for healthy growth due to variations in species, habitat, and habits. To ensure the groundwater depth remains within the suitable range for the protected vegetation, this invention includes drainage structures and groundwater level monitoring measures within the vegetation growth area. Based on the groundwater depth h (the depth from the ground surface) required for vegetation growth, the monitoring equipment monitors the groundwater level. When the monitored depth is less than h, the drainage structure lowers the groundwater level, ensuring it does not exceed h, preventing submersion and guaranteeing the healthy growth of various valuable tree species.

Detailed Implementation Methods

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the accompanying drawings.

[0020] Please see Figure 1 This utility model provides a structure for in-situ protection and flood control of vegetation in flooded areas, especially a structure for in-situ protection of valuable tree species and flood control. It includes: a protective structure 1, a first seepage-proof structure 2, a second seepage-proof structure 21, a drainage structure 3, monitoring equipment 4, and a controller (not shown in the figure) for controlling the operation of the drainage structure 3 based on the monitoring results of the monitoring equipment 4.

[0021] The protective structure 1 is arranged along the water-facing side to block the inundation zone and form an in-situ protection zone. It includes the water-facing side 1, the dike body 12, the dike crest 13, and the backwater side 14. The first seepage prevention structure 2 and the second seepage prevention structure 21 are located on both sides of the vegetation to be protected, and the first seepage prevention structure 2 is arranged inside the protective structure 1 or in the lower foundation to prevent seepage from the dike body 13 and the foundation. The seepage prevention structure type of the first seepage prevention structure 2 and the second seepage prevention structure 21 needs to be determined in conjunction with the type of protective structure. It can be a combination of earth-rock core wall dike and suspended seepage prevention wall, or earth-rock dike combined with seepage prevention wall and foundation curtain grouting, or reinforced concrete dike combined with curtain grouting, etc. The first seepage prevention structure 2 and the second seepage prevention structure 21 can effectively block the inundation zone and create a dry environment for valuable tree species. Even so, the problems of seepage and surface rainwater accumulation cannot be avoided. To prevent this problem, i.e., waterlogging, and to ensure that different varieties of precious tree species reach the most suitable groundwater level depth h for growth, this utility model sets up a drainage structure 3 at the location where vegetation needs protection. The drainage structure 3 includes a seepage well 31, a pumping device 32, and an outlet pipe 33. The seepage well 31 is located at the lowest point of the protected area to collect seepage and surface rainwater. The pumping device 32 is located on a platform inside the seepage well 31 and is connected to the outlet pipe 33. The monitoring device 4 can be a water level gauge buried underground. When the water level gauge detects that the groundwater level depth is less than h (i.e., the high water level required for the growth of the protected vegetation), the controller starts the pumping device 32 to pump the waterlogged water, accumulated water, and groundwater collected in the seepage well 31 out of the protective structure through the outlet pipe 33, thereby lowering the groundwater level and ensuring that it does not exceed h, thus preventing waterlogging.

[0022] In summary, the in-situ protection structure for precious tree species in flooded areas provided by this utility model forms an in-situ protected area by setting up a protective structure 1, a first anti-seepage structure 2, and a second anti-seepage structure 21, thus avoiding the risks and losses that may be suffered by transplanted precious tree species (i.e., vegetation that needs protection). By arranging monitoring equipment and drainage structure 3 to control the groundwater level to not exceed the growth water level h of the vegetation that needs protection, it can ensure that different varieties of precious tree species can obtain the most suitable growth environment, providing a new idea and solution for new construction projects.

[0023] In this utility model, the protective structure can be an earthen embankment, a stone embankment, a concrete or reinforced concrete embankment, a soil-rock mixed embankment, etc.; the seepage prevention structure can be a core wall, a sloping wall, a seepage prevention wall, a curtain grouting, etc.; the pumping device can be a submersible pump, a centrifugal pump, a long-shaft submersible pump, etc., and the arrangement of the seepage prevention structure should be matched according to the type of protective structure.
