Description

Technical Field

[0001] This utility model relates to the field of bank protection reinforcement technology, and in particular to a bank protection reinforcement device for soil and water conservation. Background Technology

[0002] In the fields of water conservancy projects and ecological protection, the stability of riverbank soil is directly related to the ecological security of rivers and the flood control capacity of surrounding areas. Currently, the mainstream methods of riverbank reinforcement are mainly divided into two categories: traditional hard reinforcement and simple ecological protection.

[0003] Traditional riverbank reinforcement structures have the following drawbacks: On the one hand, rigid revetments isolate the exchange of substances between water and soil, destroying microbial habitats and plant growth environments, thus isolating the riverbank ecosystem. On the other hand, geotextiles alone have weak impact resistance and are easily torn under strong water flow or flood impact during the flood season, failing to effectively intercept soil particles and leading to increased soil erosion.

[0004] Therefore, we designed a bank protection reinforcement device that utilizes soil and water conservation. Utility Model Content

[0005] This utility model discloses a bank protection reinforcement device for soil and water conservation, which aims to solve the technical problems of bank protection reinforcement.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A bank protection reinforcement device for soil and water conservation includes a modular reinforcement component, a flexible anchoring component, and an ecological buffering component. The ecological buffering component is fitted and covered on the surface of the riverbank soil. The modular reinforcement component covers the outside of the ecological buffering component. Both the upper and lower ends of the flexible anchoring component are inserted into the riverbank soil, and the main body of the flexible anchoring component covers the surface of the modular reinforcement component.

[0008] The module reinforcement component includes several rectangular frames, and several reinforcement units are installed on the inner side of the rectangular frames. Each reinforcement unit is a hollow shell structure, and several cross-shaped reinforcing ribs are fixedly arranged on the inner wall of the reinforcement unit. Mounting blocks are fixedly connected to both the upper and lower ends of the rectangular frames. Anchoring holes are opened on the surface of the mounting blocks, and anchoring rods are inserted into the inner wall of the anchoring holes. The tips of the anchoring rods are inserted into the riverbank soil.

[0009] In a preferred embodiment, the top of the reinforcement unit has several ventilation holes, the inner wall of the reinforcement unit is coated with a biocompatible coating, and the reinforcement unit is made of glass fiber reinforced plastic.

[0010] In a preferred embodiment, a first splicing block and a second splicing block are fixedly connected to both sides of the reinforcement unit, the positions of the first splicing block and the second splicing block correspond to each other, and both the first splicing block and the second splicing block are L-shaped. Two adjacent reinforcement units are spliced ​​together by the first splicing block and the second splicing block.

[0011] In a preferred embodiment, the ecological buffer component adopts a double-layer structure, with an inner layer of polypropylene geotextile and an outer layer of coconut fiber blanket, the polypropylene geotextile covering the surface of the riverbank soil.

[0012] In a preferred embodiment, the overlap width of two adjacent ecological buffer components is ≥10cm, and the overlap is fixed by geotextile stitching. The edge of the ecological buffer component extends 10cm to the outside of the module reinforcement component.

[0013] In a preferred embodiment, the flexible anchoring component includes several anchor piles, which are respectively anchored to the top and bottom of the riverbank soil. A longitudinal tie rope is fixedly connected between the two sets of anchor piles with corresponding positions. Several fixing hooks are fixedly provided on the surface of the reinforcement unit, and the longitudinal tie rope passes through the several fixing hooks in sequence.

[0014] In a preferred embodiment, the fixing hook has transverse through holes on both the left and right sides, and transverse tie ropes are inserted into the transverse through holes. The longitudinal tie ropes and transverse tie ropes are distributed crisscrossingly on the surface of the module reinforcement component.

[0015] As can be seen from the above, the bank protection reinforcement device for soil and water conservation provided by this utility model has the following technical effects.

[0016] Firstly, a three-layer protective structure is adopted, consisting of ecological buffer components, modular reinforcement components, and flexible anchoring components, forming a three-dimensional protection system from the inside out. The ecological buffer components conform to the riverbank soil, initially dispersing the soil stress; the modular reinforcement components form a rigid support through a rectangular frame and hollow reinforcement units, and the cross-shaped reinforcing ribs on the inner wall of the reinforcement units further enhance the structural strength, effectively resisting water erosion and wave impact; the flexible anchoring components are fixed to the riverbank soil through upper and lower anchor piles, and the surface of the modular reinforcement components is covered with crisscrossing tie ropes, tightly connecting each component to the riverbank soil, preventing module displacement or soil landslides, and significantly enhancing the overall anti-sliding and anti-overturning capabilities of the revetment.

[0017] Secondly, the inner wall of the reinforcement unit is coated with a biocompatible coating, which promotes the attachment of microorganisms and the growth of plant roots. In addition, the ventilation holes opened at the top of the reinforcement unit can provide oxygen exchange channels for microorganisms inside the soil, while facilitating rainwater infiltration, maintaining the air permeability and moisture content of the riverbank soil, creating a suitable environment for plant root growth, helping the restoration of riverbank vegetation, and avoiding the ecological isolation problems caused by traditional hard revetments.

[0018] Thirdly, the ecological buffer component adopts a double-layer structure of polypropylene geotextile and coconut fiber blanket. The inner polypropylene geotextile can effectively intercept soil particles and prevent soil erosion, while allowing water to penetrate and maintain soil moisture. The outer coconut fiber blanket has good water and fertilizer retention properties and can be naturally degraded. During the degradation process, it can provide organic matter to the soil and promote the growth of herbaceous plants. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figures 1-4 A bank protection reinforcement device for soil and water conservation includes a modular reinforcement component 1, a flexible anchoring component 2, and an ecological buffer component 3. The ecological buffer component 3 is attached to and covers the surface of the riverbank soil. As the first layer of structure in contact with the soil, its edge needs to extend 10cm to the outside of the modular reinforcement component 1 to ensure that the edge of the riverbank soil can also be buffered and protected.

[0029] The modular reinforcement component 1 covers the outside of the ecological buffer component 3, completely enclosing the middle area of ​​the ecological buffer component 3, leaving only the edge part of the ecological buffer component 3 that extends out; the upper and lower ends of the flexible anchoring component 2 are vertically inserted into the riverbank soil, while the main body tightly covers the surface of the modular reinforcement component 1. The modular reinforcement component 1 is bound to the riverbank soil through the crisscross structure, forming an overall stable structure.

[0030] The modular reinforcement component 1 consists of a rectangular frame 101, which is the basic support structure of the modular reinforcement component 1. Each rectangular frame 101 can be designed with a standardized size of 2-4 meters long and 1.5-2 meters high according to the width of the riverbank, which is convenient for on-site splicing. The reinforcement unit 102 is a hollow shell structure. The length, width and height of each reinforcement unit 102 can be set to 50cm×30cm×20cm. Several reinforcement units 102 are closely arranged and fixedly installed on the inner side of the rectangular frame 101. There are no gaps between adjacent reinforcement units 102, ensuring that the inner side of the rectangular frame 101 is completely covered by the reinforcement units 102, forming a continuous rigid protective layer.

[0031] The cross-shaped reinforcing ribs 103 are made of the same glass fiber reinforced plastic material as the reinforcing unit 102, and are fixedly installed in an X shape on the inner wall of the reinforcing unit 102. 3-4 sets of cross-shaped reinforcing ribs 103 are evenly distributed on the inner wall of each reinforcing unit 102. The two ends of each set of reinforcing ribs are connected to the four corners of the inner wall of the reinforcing unit 102, respectively. The cross structure disperses the external force borne by the reinforcing unit 102 and improves its impact resistance.

[0032] The mounting block 104 is a cuboid structure made of fiberglass reinforced plastic. Two to three mounting blocks 104 are fixedly connected to the top and bottom ends of each rectangular frame 101. The mounting blocks 104 are perpendicularly connected to the ends of the rectangular frame 101, and the central axis of the mounting block 104 is on the same plane as the central axis of the rectangular frame 101. Anchoring holes are formed on the surface of the mounting block 104 along a direction perpendicular to the riverbank soil. One end of the anchoring rod 105 is inserted through the anchoring hole, and the tip passes through the ecological buffer component 3 before being directly inserted into the riverbank soil to a depth of not less than 50 cm. The anchoring rod 105 fixes the rectangular frame 101 to the riverbank soil, preventing displacement of the module reinforcement component 1.

[0033] The reinforcing unit 102 has a first splicing block 107 and a second splicing block 108 integrally formed on both sides. Both the first splicing block 107 and the second splicing block 108 are L-shaped, and their positions on both sides of the reinforcing unit 102 correspond to each other. That is, the second splicing block 108 of the left reinforcing unit 102 can be fully engaged with the first splicing block 107 of the adjacent right reinforcing unit 102. During splicing, the first splicing block 107 and the second splicing block 108 of the adjacent reinforcing unit 102 are aligned, and the reinforcing unit 102 is pushed laterally to achieve engagement and fixation without the need for additional fasteners.

[0034] Meanwhile, the top of the reinforcement unit 102 is evenly provided with several ventilation holes 106 with a diameter of 2-3cm. The ventilation holes 106 penetrate the top shell of the reinforcement unit 102, which can realize the air circulation between the inside of the reinforcement unit 102 and the outside. The inner side wall of the reinforcement unit 102 (i.e. the side in contact with the ecological buffer component 3) is evenly coated with a biocompatible coating (such as polylactic acid-based coating) with a thickness of 1-2mm to ensure that it will not have an adverse effect on the ecological buffer component 3 and the organisms in the riverbank soil.

[0035] The ecological buffer component 3 adopts a double-layer composite structure, consisting of an inner layer of polypropylene geotextile 301 and an outer layer of coconut fiber blanket 302, with an overall thickness of 5-8mm. The polypropylene geotextile 301 is a high-density non-woven fabric with good tensile strength and permeability. It directly covers the surface of the riverbank soil, adhering tightly to the soil without significant gaps. The coconut fiber blanket 302 covers the outside of the polypropylene geotextile 301 and contacts the reinforcement unit 102 of the module reinforcement component 1. The loose structure of the coconut fiber provides buffering and water retention functions.

[0036] During the laying process, the overlap width of two adjacent ecological buffer components 3 is controlled to be ≥10cm. The overlap is double-stitched with high-strength geotextile stitching thread (such as polyester fiber thread) with a stitching interval of 5-8cm to ensure that there is no water seepage or soil leakage at the overlap. At the same time, the edge of the ecological buffer component 3 needs to extend 10cm to the outside of the module reinforcement component 1 to cover the edge area of ​​the riverbank soil not covered by the module reinforcement component 1, forming a complete buffer protection surface.

[0037] The flexible anchoring component 2 consists of anchor piles 201, longitudinal tie ropes 202, fixing hooks 203 and transverse tie ropes 204. Its function is to flexibly bind the module reinforcement component 1 to the riverbank soil and improve the overall stability.

[0038] Anchor piles 201 are made of reinforced concrete, cylindrical in shape, with a diameter of 15-20cm and a length of 1.5-2 meters. Several anchor piles 201 are anchored to the top and bottom of the riverbank soil, with a one-to-one correspondence between the top and bottom anchor piles 201. The insertion depth of the top anchor pile 201 is no less than 80cm, and the insertion depth of the bottom anchor pile 201 is no less than 100cm, ensuring their stability in the soil. The longitudinal tie rope 202 is a high-strength synthetic fiber rope with a diameter of 10-12mm. Its two ends are fixedly connected to the corresponding upper and lower anchor piles 201 (using bolt clips for fixation), and the tension of the longitudinal tie rope 202 can be controlled by the bolt clips to ensure a tight fit against the surface of the module reinforcement component 1.

[0039] The fixing hooks 203 are made of metal (such as stainless steel). Two to three fixing hooks 203 are evenly fixed to the surface of each reinforcement unit 102 (i.e., the side away from the ecological buffer component 3). The bottom of the fixing hook 203 is welded to the surface of the reinforcement unit 102, and the opening direction of the fixing hook 203 is perpendicular to the riverbank soil. Horizontal through holes are formed on both sides of the fixing hook 203, and the diameter of the through holes matches the diameter of the horizontal tie rope 204. The horizontal tie rope 204 is also made of high-strength synthetic fiber rope, with the same diameter as the longitudinal tie rope 202. It passes through the horizontal through holes of the fixing hooks 203 of all reinforcement units 102 at the same horizontal level, forming a horizontal tie structure. The longitudinal tie rope 202 and the horizontal tie rope 204 are distributed crisscrossingly on the surface of the module reinforcement component 1, forming a grid-like anchor structure.

[0040] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
