Hollow type revetment structure

Abstract

A hollow revetment structure includes a plurality of revetment piles arranged in rows and connected sequentially. Each revetment pile has an ecological through-hole formed in its middle, along its height. Each revetment pile has a positioning protrusion and a positioning groove at both ends along its arrangement direction, which can interlock with each other. Furthermore, each revetment pile also has a first arc-shaped groove and a second arc-shaped groove at both ends along its arrangement direction, which can be connected to form holes. Compared with existing technologies, the positioning protrusions and grooves enable sequential interlocking between adjacent revetment piles. When the revetment structure is subjected to external forces, the positioning protrusions and grooves counteract these forces, ensuring the stability of the revetment structure. Simultaneously, the first and second arc-shaped grooves, when connecting the holes, allow for reinforcement within the holes, strengthening the connection between adjacent revetment piles and thus improving the revetment strength.

Description

Technical Field

[0001] This utility model relates to the field of bank protection pile technology, specifically to a hollow bank protection structure. Background Technology

[0002] Bank protection refers to the measures taken to reinforce existing bank slopes in estuaries, rivers, lakes, and coastal areas. Bank protection is used to prevent bank slope collapse caused by wave and water flow erosion, as well as by soil pressure and groundwater seepage pressure.

[0003] Retaining piles are a common structure in water conservancy projects such as river management and coastal protection. They are mainly used to prevent soil erosion and enhance the stability of bank slopes. Depending on the materials, structure and construction technology of the retaining piles, they can be divided into various types.

[0004] Chinese patent CN222515821U discloses a riverbank revetment greening pile, including a pile body and a greening box. The pile body includes a solid section and a hollow section. The hollow section has an inner cavity and a channel hole communicating with the inner cavity. The greening box is placed in the inner cavity and is divided into aquatic plant planting area, terrestrial plant planting area and aquatic animal activity area.

[0005] The aforementioned revetment greening piles are polygonal in structure. The connection between adjacent revetment greening piles is achieved by abutting one side of the polygonal structure with one side of the adjacent revetment greening pile. However, this connection method results in a small connection between adjacent revetment greening piles, which can easily cause gaps between adjacent revetment piles under the action of water flow, affecting the revetment effect of the revetment piles. Utility Model Content

[0006] The present invention aims to overcome the defects in the prior art and provide a hollow revetment structure that is reliable in connection and simple in structure.

[0007] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a hollow revetment structure, comprising a plurality of revetment piles arranged in rows and connected in sequence; an ecological hole is formed in the middle of the revetment pile along the height direction of the revetment pile; positioning protrusions and positioning grooves that can be interlocked are formed at both ends of the revetment pile along the arrangement direction, and a first arc-shaped groove and a second arc-shaped groove that can be connected to form a hole are also formed at both ends of the revetment pile along the arrangement direction.

[0008] As a preferred embodiment of the present invention, the positioning protrusion includes a first protrusion section and a second protrusion section symmetrically arranged along the center of the first arc-shaped groove, and the positioning groove includes a first groove section that cooperates with the first protrusion section and a second groove section that cooperates with the second protrusion section, and the first groove section and the second groove section are symmetrically arranged along the center of the second arc-shaped groove.

[0009] As a preferred embodiment of this utility model, the first protruding section is formed between the water-facing surface of the revetment pile and the first arc-shaped groove, and the second protruding section is formed between the water-repellent surface of the revetment pile and the first arc-shaped groove.

[0010] As a preferred embodiment of this utility model, the first groove segment is formed between the water-facing surface of the revetment pile and the second arc-shaped groove, and the second groove segment is formed between the water-repellent surface of the revetment pile and the second arc-shaped groove.

[0011] As a preferred embodiment of this utility model, the ecological hole is installed through the revetment pile.

[0012] As a preferred embodiment of this utility model, the ecological hole is a blind hole structure extending downward from the top of the revetment pile.

[0013] As a preferred embodiment of this utility model, the inner walls of the first arc-shaped groove and the second arc-shaped groove are flush, and the first arc-shaped groove and the second arc-shaped groove are connected to form a filling through hole that penetrates the revetment pile.

[0014] As a preferred embodiment of this utility model, the revetment pile has two rows of vertical steel bars arranged along the arrangement direction of the revetment pile, and the two rows of vertical steel bars are respectively arranged on the water-facing side and the water-repellent side of the revetment pile.

[0015] As a preferred embodiment of this utility model, the revetment pile is further provided with water-facing hoops for binding several vertical steel bars on the water-facing side of the revetment pile and water-reverse hoops for binding several vertical steel bars on the back side of the revetment pile.

[0016] As a preferred embodiment of this utility model, the revetment pile is also provided with a main hoop surrounding the ecological hole.

[0018] Compared with existing technologies, the positioning protrusions and grooves enable sequential interlocking between adjacent revetment piles. When the revetment structure is affected by external forces, the positioning protrusions and grooves counteract the external forces, ensuring the stable installation of the revetment structure. At the same time, under the action of the first and second arc-shaped grooves connecting the holes, reinforcement can be carried out inside the holes as needed to strengthen the connection between adjacent revetment piles, thereby improving the revetment strength of the revetment structure.

[0025] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] like Figures 1-5 As shown, a hollow revetment structure includes a number of revetment piles 1 arranged in rows and connected in sequence; an ecological hole 2 is formed in the middle of the revetment pile 1 along the height direction of the revetment pile 1; positioning protrusions 3 and positioning grooves 4 that can be interlocked are formed at both ends of the revetment pile 1 along the arrangement direction, and a first arc-shaped groove 11 and a second arc-shaped groove 12 that can be connected to form holes are also formed at both ends of the revetment pile 1 along the arrangement direction.

[0027] The number of revetment piles 1 is set according to actual needs. Several revetment piles 1 are connected end to end to form a row of revetment structures. Adjacent revetment piles 1 are connected by interlocking positioning protrusions 3 and positioning grooves 4, thereby realizing the interlocking between several revetment piles 1 set in a row.

[0028] The positioning protrusion 3 includes a first protrusion section 31 and a second protrusion section 32 symmetrically arranged along the center of the first arc-shaped groove 11. The positioning groove 4 includes a first groove section 41 that cooperates with the first protrusion section 31 and a second groove section 42 that cooperates with the second protrusion section 32. The first groove section 41 and the second groove section 42 are symmetrically arranged along the center of the second arc-shaped groove 12.

[0029] The first protruding section 31 is set near the water-facing side of the revetment pile 1, and the second protruding section 32 is set near the water-repellent side of the revetment pile 1. Similarly, the first grooved section 41 is set near the water-facing side of the revetment pile 1, and the second grooved section 42 is set near the water-repellent side of the revetment pile 1. When the first protruding section 31 of the adjacent revetment pile 1 is engaged in the first grooved section 41, the second protruding section 32 is simultaneously engaged in the second grooved section 42. At this time, the water-facing surfaces of the adjacent revetment pile 1 are flush, and the water-repellent surfaces of the adjacent revetment pile 1 are also flush.

[0030] The first protruding section 31 is formed between the water-facing surface of the revetment pile 1 and the first arc-shaped groove 11, and the second protruding section 32 is formed between the backwater surface of the revetment pile 1 and the first arc-shaped groove 11. The first protruding section 31 is not directly set on the water-facing surface of the revetment pile 1. Therefore, when the water-facing surface of the revetment pile 1 is impacted by water flow, the impact needs to be transferred through the revetment pile 1 to the first protruding section 31 to prevent the first protruding section 31 from being directly damaged by force, and also to prevent the first protruding section 31 from being directly corroded by the direct impact of water flow. Similarly, the second protruding section 32 is not directly set on the backwater surface of the revetment pile 1. Therefore, when the backwater surface of the revetment pile 1 is squeezed by soil, the impact needs to be transferred through the revetment pile 1 to the second protruding section 32 to prevent the second protruding section 32 from being directly damaged by force, and also to prevent the second protruding section 32 from being directly corroded by soil.

[0031] The first groove section 41 is formed between the water-facing surface of the revetment pile 1 and the second arc-shaped groove 12, and the second groove section 42 is formed between the backwater surface of the revetment pile 1 and the second arc-shaped groove 12. The first groove section 41 is not directly set on the water-facing surface of the revetment pile 1. Therefore, when the water-facing surface of the revetment pile 1 is impacted by water flow, the impact needs to be transferred through the revetment pile 1 to the first groove section 41 to prevent the first groove section 41 from being directly damaged by force and to prevent the first groove section 41 from being directly corroded by the direct impact of water flow. Similarly, the second groove section 42 is not directly set on the backwater surface of the revetment pile 1. Therefore, when the backwater surface of the revetment pile 1 is squeezed by soil, the impact needs to be transferred through the revetment pile 1 to the second groove section 42 to prevent the second groove section 42 from being directly damaged by force and to prevent the second groove section 42 from being directly corroded by soil.

[0032] When the revetment pile 1 is impacted by the water flow, the water flow pushes the revetment pile 1 towards the bank. Under the action of the second protruding section 32 and the second groove section 42, and with the support of the adjacent revetment pile 1, the movement of the revetment pile 1 towards the bank is restricted, ensuring the stability of the revetment pile 1. When the revetment pile 1 is squeezed by the soil, the squeezing force pushes the revetment pile 1 towards the river. Under the action of the first protruding section 31 and the first groove section 41, and with the support of the adjacent revetment pile 1, the movement of the revetment pile 1 towards the bank is restricted, ensuring the stability of the revetment pile 1.

[0033] Ecological holes 2 are installed through the revetment piles 1. Green plants can be planted inside the ecological holes 2 as needed, which not only improves the aesthetics of the revetment piles 1, but also makes the revetment piles 1 form an ecological structure corresponding to the river.

[0034] Ecological hole 2 is a blind hole structure extending downward from the top of the revetment pile 1. The depth of ecological hole 2 is set according to actual needs.

[0035] The inner walls of the first arc-shaped groove 11 and the second arc-shaped groove 12 are flush, and the first arc-shaped groove 11 and the second arc-shaped groove 12 are connected to form a filling through hole 13 that penetrates the revetment pile 1. The filling through hole 13 can be grouted as needed to improve the connection strength between adjacent revetment piles 1 and ensure the overall stability of the revetment structure.

[0036] The revetment pile 1 has two rows of vertical steel bars 5 arranged along the arrangement direction of the revetment pile 1. The two rows of vertical steel bars 5 are respectively arranged on the water-facing side and the back side of the revetment pile 1. Under the action of the vertical steel bars 5, the strength of the water-facing side and the back side of the revetment pile 1 is strengthened, ensuring the service strength and stability of the revetment pile 1.

[0037] The revetment pile 1 is also equipped with water-facing stirrups 6 for binding several vertical steel bars 5 on the water-facing side of the revetment pile 1 and water-reverse stirrups 7 for binding several vertical steel bars 5 on the back side of the revetment pile 1. The water-facing stirrups 6 and water-reverse stirrups 7 are used to further strengthen the stability of the vertical steel bars 5, thereby further improving the strength and stability of the revetment pile 1.

[0038] The revetment pile 1 is also equipped with a main hoop 8 surrounding the ecological hole 2. The main hoop 8 is also tied to a number of vertical steel bars 5 on the water-facing side of the revetment pile 1 and a number of vertical steel bars 5 on the water-repellent side of the revetment pile 1.

[0039] The upstream stirrups 6 and downstream stirrups 7 are used to reinforce the vertical steel bars 5 on the upstream and downstream sides of the revetment pile 1 respectively, while the main stirrups 8 are used to reinforce the vertical steel bars 5 on both the upstream and downstream sides of the revetment pile 1 at the same time, thereby further improving the strength and stability of the revetment pile 1.

[0040] The revetment pile 1 is also equipped with reinforcing steel bars 9 to strengthen the structural strength of the first arc groove 11 and the second arc groove 12. The reinforcing steel bars 9 are tied to the main stirrups 8.

[0041] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.

[0042] Although this document uses numerous reference numerals from the accompanying drawings—such as: revetment pile 1, first arc-shaped groove 11, second arc-shaped groove 12, filling through hole 13, ecological hole 2, positioning protrusion 3, first protruding section 31, second protruding section 32, positioning groove 4, first groove section 41, second groove section 42, vertical reinforcement 5, water-facing stirrup 6, backwater stirrup 7, main stirrup 8, and reinforcing reinforcement 9—the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
