Description

Technical Field

[0001] This utility model relates to the field of waterway slope protection, and in particular to a slope protection structure for waterway side slopes. Background Technology

[0002] Channel slopes refer to the transitional area between water and shoreline in water transport, that is, the slopes with a certain gradient on both sides of the channel. Protecting channel slopes is crucial for ensuring the safety and smooth flow of waterways. Therefore, scientifically and rationally delineating the protection scope of channel slopes is a key measure to ensure slope stability and the normal operation of the waterway.

[0003] In recent years, ecological slope protection technology has been applied in inland waterway management, aiming to restore the ecological environment around the waterway, improve the landscape, enrich the biodiversity of rivers and banks, and promote the sustainable development of inland waterways. To protect waterway slopes, existing technologies include a slope protection structure, such as Chinese Patent Application No. CN202421209741.6, which comprises multiple slope protection units distributed in a matrix on the slope surface. Each slope protection unit includes: a base plate along a first direction, with a pressure plate at one end and a supporting step at the second end; when the slope protection units are spliced ​​along the first direction, the pressure plate and supporting step of adjacent slope protection units abut against each other; and a water-retaining ring connected to the upper surface of the base plate. The slope protection unit of this utility model includes a water-retaining ring and a soil-stabilizing ring. The soil-stabilizing ring forms a soil-stabilizing area below the base plate to store soil for plant growth. The water-retaining ring isolates water flow above the base plate, allowing water on the slope to flow out quickly through the drainage channels between the water-retaining rings. This design minimizes the impact of wave impact on the plants inside the water-retaining ring, which is beneficial for growth and soil stabilization, and ensures the ecological function of the slope.

[0004] However, existing technologies with similar technical content have the following problems: insufficient overall structural strength and lack of reliable anchoring points.

[0005] Therefore, there is an urgent need for a slope protection structure for waterway slopes to solve the above-mentioned technical problems. Summary of the Invention

[0006] To address the problems of insufficient overall structural strength and lack of reliable anchoring points in existing waterway slope protection structures, this utility model proposes a waterway slope protection structure to solve the above-mentioned technical problems. The technical solution is as follows.

[0007] A slope protection structure for a waterway slope includes a pair of elongated mounting pillows that extend along a first direction and are parallel to each other;

[0008] Multiple longitudinal connecting cables and multiple transverse connecting cables are installed between the mounting pillows;

[0009] The longitudinal connecting cables extend along a second direction and are parallel to each other, the second direction being perpendicular to the first direction, and the longitudinal connecting cables are tensioned and fixed between the pair of mounting pillows;

[0010] The transverse connecting cable extends along the first direction, and the transverse connecting cable is fixedly connected to the longitudinal connecting cable by a fastener, and the fastener is provided at each intersection of the transverse connecting cable and the longitudinal connecting cable;

[0011] A prefabricated pressure block is provided in a rectangular partition formed by adjacent longitudinal connecting cables and adjacent transverse connecting cables. The prefabricated pressure block has a connection structure on both sides in the first direction for fixing adjacent prefabricated pressure blocks to each other.

[0012] The longitudinal connecting cable is provided with a fixing structure for fixing in conjunction with the connecting structure, so that adjacent precast blocks are linked and fixed through the longitudinal connecting cable.

[0013] The mounting pillow is equipped with an anchoring structure to strengthen its fixation to the soil.

[0014] Furthermore, the anchoring structure provided on the mounting pillow includes a plurality of fixing holes opened on the mounting pillow, and the fixing holes are arranged along the first direction on the mounting pillow, so that the anchor can be driven into the soil below the fixing holes to enhance the anchoring.

[0015] Furthermore, several conical protrusions are provided below the prefabricated block for easy fixation.

[0016] Furthermore, the precast block has a planting cavity, and the top of the planting cavity is formed by penetrating the precast block to form an open opening, exposing the cavity to the outside. The bottom of the planting cavity has several root outlet holes penetrating the precast block for the downward growth of plant roots.

[0017] Furthermore, a conical protective sleeve is provided around the outer periphery of the opening.

[0018] Furthermore, the fixing member is a sphere, and the transverse connecting cable and the longitudinal connecting cable are embedded in the sphere.

[0019] Furthermore, the connection structure includes an upper ear 6 on one side of the precast block 5 and a lower ear 7 on the opposite side. Each upper ear 6 and the corresponding lower ear 7 of the adjacent precast block 5 are matched. The bottom of the upper ear 6 and the top of the lower ear 7 are respectively provided with a relief groove 8. The lower ear 7 and upper ear 6 of two adjacent precast blocks 5 are overlapped. The longitudinal connecting cable 2 is provided in the cable hole formed by the overlap of the two relief grooves 8.

[0020] Furthermore, the fixing structure includes a fixing sleeve coaxially mounted on the longitudinal connecting cable. The upper and lower sides of the fixing sleeve are respectively provided with fixing pins perpendicular to the axis of the longitudinal connecting cable. The upper ear and the lower ear are respectively provided with pin holes. The fixing pins are used to be simultaneously inserted into the pin holes of the upper ear and the lower ear of the stacked adjacent precast blocks.

[0021] The beneficial effects of this utility model are as follows: This utility model forms a stable grid frame by setting parallel installation pillows and crisscrossing tension connecting cables. Combined with the linkage fixing design of prefabricated pressure blocks and connecting structures, it significantly improves the overall strength and deformation resistance of the slope protection structure. The cooperation between the anchoring structure and the conical protrusion enhances the anchoring effect between the installation pillows and the soil, solving the problem of the lack of reliable fixing points in traditional slope protection. The design of the planting cavity and root outlet hole realizes the ecological restoration function, and the conical casing protects the plant seedlings. The ingenious cooperation between the spherical fixing component and the connecting ear with pin hole not only ensures the rapid assembly of the prefabricated pressure block but also realizes the linkage fixing of the longitudinal connecting cables, forming a multi-reinforcement system, fundamentally solving the technical defects of insufficient slope protection structure strength and unreliable anchoring in the prior art.
