Abstract
Description
Technical Field
[0001] The utility model relates to a protective structure for the bank slope in front of a river bank anti-scour wall, in particular to an anti-scour concrete collapse preparation body for the bank slope in front of the river bank anti-scour wall with high stacking accuracy and strong anti-scour capability, belonging to the technical field of water conservancy engineering. Background Art
[0002] As a bank protection structure, the anti-scour wall is usually protected by an anti-collapse body on the bank slope in front to prevent the bank slope from being eroded and washed away, which may lead to insufficient anchoring depth of the anti-scour wall and the risk of overturning and sliding. Currently, gabions or rock piles are mainly used as anti-scour and collapse bodies. The construction of gabions as collapse bodies requires the assembly and connection of binding boxes, filling with stones, and looking into the capping process. During construction, the stones inside the gabions are prone to loosening or falling, posing a safety hazard and low construction efficiency. In areas with steep slopes, water flow and wind and rain erosion can easily cause the stones inside the gabions to loosen or fall, affecting the anti-scour effect of the river bank. In addition, the cost of repairing and maintaining gabions is high, and it is difficult to replenish stones from the inside of the gabions, requiring professional maintenance personnel and equipment.
[0003] As a landslide-preventive structure, rockfill revetments face challenges such as high rock requirements and difficulty transporting them. Consequently, this revetment method is most effective in areas with abundant rock resources, but is not widely used elsewhere. The long-term impact of rockfill, especially during floods, can easily lead to rock loss and consequently soil erosion on the bank slopes. Furthermore, from an ecological perspective, rockfill revetments severely damage the plant growth environment. To achieve a better ecological landscape, additional remedial measures are required, increasing costs.
[0004] The common problem of the above two methods is that they have poor ability to adapt to foundation deformation and are prone to losing integrity after slope erosion, requiring repair, so the application and maintenance costs are high. Utility Model Content
[0005] The utility model aims to provide a river bank anti-scour wall front slope anti-scour concrete collapse preparation body which has simple structure, convenient construction, high stacking precision, strong anti-scour ability and strong adaptability to foundation deformation.
[0006] The utility model is achieved through the following technical solutions:
[0007] A concrete anti-scour preparation body for the front slope of a riverbank anti-scour wall, the collapse preparation body being a quadrangular pyramid hexahedron structure; two opposite side surfaces of the collapse preparation body are vertical surfaces, a first horizontal through hole is provided on the lower side between the two vertical surfaces, the other two opposite side surfaces of the collapse preparation body are inclined surfaces, a second horizontal through hole is provided in the middle between the two inclined surfaces, the first horizontal through hole and the second horizontal through hole are perpendicular to each other; a square groove is provided in the middle of the top surface of the collapse preparation body, and a lifting ring is embedded in the square groove.
[0008] The object of the present utility model can also be further achieved by the following technical measures.
[0009] For the aforesaid concrete pre-collapse body for preventing bank slope scouring in front of the river bank anti-scour wall, the inclination angle α of the inclined surface is 60° - 80°.
[0010] For the aforesaid concrete pre-collapse body for preventing bank slope scouring in front of the river bank anti-scour wall, the ratio h / H of the distance h between the first horizontal through hole and the bottom of the pre-collapse body to the total height H of the pre-collapse body is 0.2 - 0.3.
[0011] For the aforesaid concrete pre-collapse body for preventing bank slope scouring in front of the river bank anti-scour wall, the ratio L / H of the depth L of the square groove to the total height H of the pre-collapse body is 0.1 - 0.2.
[0012] For the aforesaid concrete pre-collapse body for preventing bank slope scouring in front of the river bank anti-scour wall, the hanging ring is in a U shape.
[0013] The volume of a single pre-collapse body of the present utility model is small and the weight is light. It can be carried and stacked manually or with simple tools, and the construction is very convenient. Two adjacent pre-collapse bodies of the same height can be stacked with their tops and bottoms tightly against each other in the opposite direction. The stacking installation accuracy is high, and the pre-collapse body can be prefabricated at the construction site, with high construction efficiency. Each layer of pre-collapse bodies is flexibly connected in series longitudinally and transversely with steel bars. When stacked in multiple layers, a multi-layer flexible integral anti-scouring structure is arranged along the river bank, making the whole pre-collapse body have good integrity and strong adaptability to foundation deformation. Even if the bank slope is eroded and subsided due to water flow scouring, the pre-collapse body can follow the subsidence of the bank slope, thus ensuring the anchoring depth of the anti-scour wall. At the same time, the gaps between the pre-collapse bodies are small, which can effectively prevent the water flow from scouring and eroding the bank slope, improve the stability and durability of the bank slope, and reduce the risk of soil erosion and bank collapse. In addition, the laying section of the pre-collapse body can be wider at the bottom and narrower at the top, presenting a right-angled trapezoidal section, so that the upper part can be backfilled with planting soil to achieve a better ecological landscape effect. If the pre-collapse body is damaged, it can be directly replaced, and the steel bars connecting the pre-collapse bodies can be reconnected by welding, greatly reducing the repair and maintenance costs.
[0014] The advantages and features of the present utility model will be illustrated and explained by the following non-restrictive description of the preferred embodiments, which are given only as examples by referring to the attached drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 3 is a schematic structural view of the present utility model stacked on the river bank slope. DETAILED DESCRIPTION
[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0019] In this embodiment, the side of the bank slope of the anti-scour wall is the front.
[0020] like Figure 1 and Figure 2 As shown, the collapse preparation body 1 of the present invention has a quadrangular pyramid hexahedron structure. Two opposing sides of the collapse preparation body 1 are vertical surfaces 11. A first horizontal through hole 12 is provided on the underside between the two vertical surfaces 11. The ratio of the spacing h between the first horizontal through hole 12 and the bottom of the collapse preparation body 1 to the total height H of the collapse preparation body 1 is h / H = 0.2-0.3. In this embodiment, h / H = 0.21. This suitable spacing h ensures a more reliable connection between the collapse preparation bodies 1. The other opposing sides of the collapse preparation body 1 are inclined surfaces 13. The inclination angle α of the inclined surfaces 13 is 60°-80°. In this embodiment, α is 70°. This suitable inclination angle ensures that the gap between the collapse preparation bodies 1 is small and not easily eroded by river water. A second horizontal through hole 14 is provided in the middle between the two inclined surfaces 13. The first and second horizontal through holes 12 and 14 are perpendicular to each other, facilitating the connection of the collapse preparation bodies 1 in both the horizontal and vertical directions after steel bars pass through the two holes. A square groove 15 is provided in the middle of the top surface of the prepared collapse body 1. The ratio of the depth L of the square groove 15 to the total height H of the prepared collapse body is L / H = 0.1-0.2, and in this embodiment, L / H = 0.17. A lifting ring 16 is embedded in the square groove 15 to facilitate lifting the prepared collapse body. The lifting ring 16 is in the shape of a "X" and is firmly embedded. The lifting ring 16 is hidden within the structure through the top square groove 5. Two adjacent prepared collapse bodies 1 of the same height can be stacked close together with their tops and bottoms facing each other. In this way, the top and bottom surfaces of each layer of prepared collapse bodies are flat, facilitating further stacking of the upper layer.
[0021] The utility model is a concrete structure. Concrete materials are relatively common, which can reduce the use of stone materials and can adapt to the situation where local stone resources are insufficient or the price is high. Moreover, it can be prefabricated on the construction site and carried out simultaneously with the stacking of the prepared collapse body. Prefabrication and stacking are carried out at the same time, forming a two-section flow construction, which is more efficient than the construction using stone stacking and gabion filling.
[0022] The construction process of this utility model is as follows:
[0023] like Figure 3As shown, first excavate the foundation pit in front of the anti-collision wall 2, clear the surface, backfill and compact the foundation, and lay the anti-seepage soil non-woven fabric 3. Stack the bottom layer of the prepared collapse body 1, with the top and bottom of the two adjacent prepared collapse bodies 1 stacked oppositely and staggered, and the adjacent inclined surfaces 13 and vertical surfaces 11 close to each other. Then, pass multiple steel bars 4 through the first horizontal through hole 12 and the second horizontal through hole 14 respectively, and weld the ends of the steel bars 4 with short steel bars 5 to anchor them. In this way, multiple prepared collapse bodies 1 can be connected in series along the longitudinal and transverse directions to form a whole. Use the same method to stack the upper layer of prepared collapse bodies 1 until the stacking is completed. The cross-section of the prepared collapse body 1 is a right-angled trapezoid with a wide bottom and a narrow top. Finally, the original soil is backfilled to form a bank slope, and the bank slope can be backfilled with planting soil to restore the vegetation landscape.
[0024] In addition to the above embodiments, the present invention may also have other implementation methods. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope required by the present invention.
