Description

Technology Field

[0001] The present invention relates to a system for improving sediment capture efficiency in a temporary sedimentation basin, and more specifically, to a system for improving sediment capture efficiency in a temporary sedimentation basin that reduces the flow velocity of water within the basin and induces the effective settling of sediment. The present invention was filed as part of the project “Standardization Plan for the Design and Maintenance of Disaster Mitigation Facilities Due to Increased Flood and Sediment Runoff” promoted by the Ministry of the Interior and Safety [NDMI-Basic-2023-13]. Background Technology

[0002] Generally, temporary sedimentation basins are installed at construction or civil engineering sites to prevent suspended solids contained in rainwater or construction water from flowing into rivers or drainage systems. In other words, these temporary sedimentation basins are installed to prevent soil runoff, prevent water pollution, protect the environment, and comply with legal regulations, and are typically prepared in the form of small reservoirs made of soil or temporary structures.

[0003] However, even if such temporary sedimentation basins are installed, if the flow velocity of the inflow water is high in the sediment storage section where sediment is captured, there is a problem where sediment does not settle sufficiently and flows downstream. Therefore, to resolve this, there is a need for a new method that can reduce the flow velocity and promote sediment sedimentation.

[0004] As a prior art document for solving the problems of such conventional temporary sedimentation tanks, Korean Registered Patent No. 10-2756032 discloses a modular type temporary sedimentation tank equipped with an overflow baffle.

[0005] However, according to these conventional technologies, there is still a problem in that when the flow rate is fast or the suspended matter is light, soil and pollutants are not settled in the sedimentation tank but flow out. Prior art literature

[0006] (Prior Art 1) Korean Patent No. 10-2756032 (January 13, 2025) The problem to be solved

[0007] The present invention has been devised to solve the problems of the prior art described above, and its purpose is to reduce the flow velocity of the water within the sedimentation tank and induce sedimentation through a filter-type panel installed within the temporary sedimentation tank. means of solving the problem

[0008] A system for improving the efficiency of capturing sediment in a temporary sedimentation basin according to a preferred embodiment of the present invention comprises a reservoir connected to a pipe for discharging water from a construction site so that the water can be stored, and discharged when the stored water reaches a preset water level; and a panel section provided in the form of a panel corresponding to the width of the reservoir and installed perpendicular to the direction of flow of water flowing into the reservoir, wherein the panel section reduces the flow velocity of the water so that sediment and pollutants suspended in the water can settle in the reservoir. Effects of the invention

[0009] By means of the solution to the above problem, the present invention has the effect of reducing the flow velocity within the temporary sedimentation basin due to the installation of panels, allowing sediment to settle more easily and increasing the sediment capture efficiency.

[0010] In addition, according to the present invention, soil of 0.1 mm or less is adsorbed onto the filter through a filter-type panel, thereby reducing the increase in soil runoff, which is a factor causing downstream disasters due to work at construction sites.

[0011] In addition, according to the present invention, by controlling the flow velocity within the sedimentation basin through the panel, it is possible to induce the concentrated accumulation of sediment in a specific section.

[0012] In addition, according to the present invention, the panel can be easily moved or replaced as needed, and maintenance can be easily performed by removing soil of 0.1 mm or less by replacing only the filter before dredging, or by dividing and dredging the soil accumulated inside the first panel and the second panel.

[0013] In addition, according to the present invention, the size of the temporary sedimentation basin can be reduced by increasing the sedimentation effect, and it is easy to install even in small-scale workplaces with narrow spatial constraints, and there is a cost-saving effect.

Specific details for implementing the invention

[0015] The terms used in this specification will be briefly explained, and the invention will be described in detail.

[0016] The terms used in this invention have been selected based on currently widely used general terms while considering their functions within the invention; however, these terms may vary depending on the intent of those skilled in the art, case law, the emergence of new technologies, etc. Therefore, the terms used in this invention should be defined not merely by their names, but based on their meanings and the overall context of the invention.

[0017] When a part of a specification is described as “comprising” a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components.

[0018] Embodiments of the present invention are described below with reference to the attached drawings so that those skilled in the art can easily implement them. However, the present invention may be embodied in various different forms and is not limited to the embodiments described herein.

[0019] Specific details regarding the problem to be solved by the present invention, the means for solving the problem, and the effects of the invention are included in the embodiments and drawings described below. The advantages and features of the present invention, and the methods for achieving them, will become clear by referring to the embodiments described below in detail together with the accompanying drawings.

[0020] Hereinafter, the system for improving sediment capture efficiency in a temporary sedimentation basin according to the present invention will be described in detail with reference to the attached drawings.

[0021] A system for improving the efficiency of capturing sediment in a temporary sedimentation basin according to a preferred first embodiment of the present invention, with reference to FIGS. 1 and 2, comprises a reservoir (100) connected to a pipe that discharges water from a construction site so that the water can be stored and discharged when the stored water reaches a preset water level, and a panel section (200) provided in the form of a panel corresponding to the width of the reservoir (100) and installed perpendicular to the direction of flow of water flowing into the reservoir (100). The panel section (200) reduces the flow velocity of the water so that sediment and pollutants suspended in the water can settle in the reservoir.

[0022] More specifically, development projects such as civil engineering works transform areas previously covered by natural soil into impermeable basins made of asphalt or concrete. Due to the increased volume of flood and sediment runoff resulting from such construction, temporary sedimentation basins in the form of retention ponds are installed to minimize damage to the development area and downstream regions. In this context, the present invention serves to minimize sediment loss by reducing the flow velocity of the water stored and flowing within the temporary sedimentation basin, and to prevent pollutants from being discharged downstream.

[0023] For example, the reservoir (100) serves to temporarily store water from the construction site and to allow water to be received, while also allowing soil and pollutants mixed in the water to settle. The reservoir (100) is provided with a receiving space formed by sinking in a rectangular shape, with the perimeter enclosed by a wall. At this time, the retaining wall (101) surrounding the receiving space of the reservoir (100) is provided in the form of an embankment to prevent the stored water from overflowing and leaking out. Additionally, the lower part of the receiving space of the reservoir (100) is provided with a soil retention section (102) where soil and pollutants in the water settle.

[0024] Additionally, the reservoir (100) includes an inflow control unit (110) that is arranged to pass through one side so that water from the construction site can flow into an internal receiving space, and a discharge control unit (120) that is arranged on the other side of the reservoir (100) so that the received water can be discharged.

[0025] The above-mentioned inflow control unit (110) includes an inflow channel (111) provided in the direction of the construction site and connected to a pipe through which water from the construction site is discharged. The above-mentioned discharge control unit (120) includes a discharge channel (121) provided in the opposite direction of the inflow control unit (110), connected to the outside of the reservoir (100), and extended to allow water to be discharged.

[0026] Next, the panel section (200) is installed in the sediment storage section (102) within the reservoir (100) and serves to reduce the flow velocity of the water. For example, the panel section (200) may be provided in multiple units and spaced apart from one another, and the installation height, number of units, and spacing distance may be selectively provided. Furthermore, the panel section (200) is installed to correspond to the width within the reservoir (100) and is arranged in a direction perpendicular to the direction of water flow. That is, the panel section (200) is designed to allow the flow of water flowing into the reservoir (100) to be directly interfered with.

[0027] Additionally, the panel section (200) is installed in multiple units spaced apart from one another, thereby partitioning the receiving space within the reservoir (100). In this embodiment, the installation of two panel sections (200) is described as an example. First, the panel section (200) is composed of a first panel (201) positioned in close proximity to the inflow control unit (110) and a second panel (202) positioned in close proximity to the discharge control unit (120). Accordingly, the panel section (200) is configured so that the sediment storage unit (102) within the reservoir (100) can be partitioned into three zones, and sedimentation of sediment and pollutants can be concentrated in any one of the partitioned spaces. At this time, the first panel (201) is installed at a height corresponding to the upper part of the sediment storage unit (102). In addition, the second panel (202) can be installed at a height of 0.2m to 0.4m higher than the first panel (201). That is, referring to FIG. 3, the panel section (200) primarily reduces the flow velocity and settles the sediment through the first panel (201). Then, referring to FIG. 4, the sediment can be secondarily settled through the second panel (202). At this time, as the panel section (200) is installed in multiple units spaced apart from each other, the sediment can be induced to settle intensively in a specific section, and the sediment capture efficiency can be improved.

[0028] Additionally, referring to FIG. 5, the panel portion (200) includes a detachable mounting member (210) in the form of a square beam installed on the bottom surface of the reservoir (100) so as to be easily attached and detached within the reservoir (100), a mesh plate member (220) provided to be selectively connected to the upper part of the detachable mounting member (210) by means of bolt fastening, etc., and having one side provided in a mesh shape, and a filter member (230) formed to be inserted into the mesh plate member (220).

[0029] The above detachable mounting member (210) is formed such that a clamp or a fastening groove is provided at the upper end to be fastened to the mesh plate member (220), and can be selectively fixed to the bottom surface within the reservoir (100). That is, the above detachable mounting member (210) serves to allow the arrangement of the panel part (200) to be selectively provided.

[0030] The above mesh plate member (220) is formed with an open top end and is configured to selectively form a receiving space in the shape of either a rectangular prism or a trapezoidal prism. Additionally, each side of the above mesh plate member (220) is provided in a mesh shape so that water or soil can pass through.

[0031] The filter member (230) is a panel-shaped filter and is configured to adsorb soil of 0.1 mm or less. Additionally, the filter member (230) is formed to correspond to the receiving space of the mesh plate member (220) so that it can be inserted into the mesh plate member (220) and easily replaced.

[0032] At this time, FIG. 5(a) is an example of the shape of the panel part (200) installed when the reservoir (100) serving as a sedimentation basin is provided relatively narrowly and the inner wall of the reservoir (100) is provided in the shape of a rectangular prism. FIG. 5(b) is an example of the panel part (200) installed in the shape of a trapezoidal wall when the reservoir (100) serving as a sedimentation basin is provided relatively large and the inner wall of the reservoir (100) is formed at an angle for slope stability.

[0033] Accordingly, according to the present invention, the installation of panels reduces the flow velocity within the temporary sedimentation basin and allows sediment to settle more easily, thereby increasing the efficiency of sediment capture. In addition, by adsorbing sediment of 0.1 mm or less onto the filter through the filter-type panel, it is possible to reduce the increase in sediment runoff, which is a factor causing disasters in the downstream area due to work at the construction site.

[0034] In addition, according to the present invention, by controlling the flow velocity within the sedimentation basin through the panel, it is possible to induce the concentrated accumulation of sediment in a specific section.

[0035] In addition, according to the present invention, the panel can be easily moved or replaced as needed, and maintenance can be easily performed by removing soil of 0.1 mm or less by replacing only the filter before dredging, or by dividing and dredging the soil accumulated inside the first panel and the second panel.

[0036] In addition, according to the present invention, the size of the temporary sedimentation basin can be reduced by increasing the sedimentation effect, and it is easy to install even in small-scale workplaces with narrow spatial constraints, and there is a cost-saving effect.

[0037] The embodiments described above should be understood as exemplary in all respects and not limiting, and the scope of the invention is defined by the claims set forth below rather than by the detailed description above, and all modifications or variations derived from the meaning and scope of the claims and equivalent concepts thereof should be interpreted as being included within the scope of the invention.
