Description

Technical Field

[0001] This utility model relates to a slope protection pile, belonging to the field of slope protection engineering technology. Background Technology

[0002] Slope protection piles are an important component in slope protection projects such as foundation pits, slopes, and river channels. They resist water erosion and prevent significant soil loss, effectively protecting river width, preventing sewage from entering the river, and maintaining the balance of the river ecosystem. Pile foundations can be precast piles, cast-in-place piles, or bored cast-in-place piles. The shape of precast concrete piles can be designed and manufactured according to needs. For example, tenon and groove structures can be set on both sides of the precast pile, allowing adjacent precast piles to fit together to solve problems such as water leakage at the joint. Patent CN221919452U discloses a spliced ​​slope protection pile assembly, which uses stepped grooves and recesses on both sides of the pile body to assemble two piles using the insertion and interlocking of the stepped grooves and recesses. However, the outlines of the stepped grooves and recesses in this structure are formed by splicing regular planes, requiring the piles to be aligned in a straight line for smooth insertion and interlocking, making it unsuitable for curved slope protection projects. Furthermore, the compressive and tensile strength of existing slope protection piles needs further improvement. Utility Model Content

[0003] In order to solve the problems existing in the prior art, this utility model provides a slope protection pile that has good load-bearing performance in both pressure and tension transmission directions, and can be applied to projects with different bending types and functions.

[0004] This utility model achieves the above objectives by adopting the following technical solutions: A slope protection pile includes a pile body, wherein a mortise and a tenon are respectively provided on the left and right sides of the pile body. The mortise and tenon extend longitudinally along the height direction of the pile body, and the cross-section of the mortise and tenon has an arc-shaped profile with a central angle greater than π. The mortise has a side insertion opening on the left side of the pile body, and the mortise has an end insertion opening on the upper or lower end of the pile body, so that the tenon on one pile body can move along the height direction of the pile body and be inserted into the mortise on the other pile body.

[0005] Preferably, the end of the mortise is located on the upper end face of the pile body, and the lower end of the mortise is closed.

[0006] Preferably, the mortise is formed by an inner nested tube embedded in the pile body, and the tenon is formed by an outer protruding sleeve fixedly connected to the right side of the pile body.

[0007] Furthermore, a first side plate is fixed to the left side of the outer convex sleeve, and the first side plate extends from the right side of the pile body; a second side plate is provided on both sides of the side opening of the inner nested tube, and the left side of the second side plate is flush with the left side of the pile body.

[0008] Preferably, the outer convex sleeve can be filled with grout.

[0009] Preferably, the outer convex sleeve and the inner nested sleeve are each composed of several pipe segments spaced apart along the height direction of the pile.

[0010] In a preferred embodiment, a side pile is provided on the rear side of the pile body. The side pile extends along the height direction of the pile body, and the cross-sectional profile of the side pile and the pile body form a T-shaped structure.

[0011] Preferably, a reinforcing cage is embedded inside the pile body and the side pile, and the tenon and mortise are fixedly connected to the reinforcing cage.

[0012] Preferably, the lower ends of the pile body and the side piles are configured as pointed shapes.

[0013] Preferably, the pile body and side piles are formed by concrete pouring and curing.

[0014] The beneficial effects of this utility model include, but are not limited to: The slope protection pile provided by this utility model (1) Two slope protection piles are assembled and connected by the socketing of the tenon and the groove. The central angle of the arc-shaped outline of the cross section of the groove and the tenon is greater than π. When the slope protection pile is subjected to force in the horizontal direction, the tenon will not come out of the groove, so that the slope protection piles form a self-locking connection. (2) The arc-shaped outline structure of the tenon and the groove can make the tenon and the groove rotate relative to each other around the center. In this way, the splicing angle between two adjacent slope protection piles can be adjusted, so that the slope protection pile can rotate arbitrarily around the tenon and the groove, which is suitable for different scenarios. (3) The outer convex sleeve and the inner nested pipe are composed of several pipe sections spaced apart along the height of the pile body, which can save raw materials and reduce the frictional resistance during assembly. In actual application, the grouting material can be filled into the pipe section or not filled according to the function of the slope protection project. When the grouting material is filled, the splicing joint between the piles can be sealed to prevent the slope protection pile from seeping water; when the grouting material is not filled, the slope protection pile can have the function of seepage. (4) The outer convex sleeve and inner nested tube are connected to the steel cage, so that the mortise and tenon form a tie structure through the steel cage, which improves the pull-out strength. (5) The design of the side piles can increase the outer surface area of ​​the slope protection piles, increase the friction between the slope protection piles and the soil, and improve the stability of the slope protection piles in the soil. On the other hand, the side piles can significantly improve the section bending modulus of the slope protection piles and enhance the soil and water retention capacity of the slope protection piles. The various structures cooperate with each other, so that the slope protection piles have good load-bearing performance in both the pressure and tension transmission directions. (6) The slope protection piles provided by this utility model can also be applied to retaining walls. When installing, the side piles should be away from the soil. The introduction of the side piles can significantly improve the stability of the slope protection piles. Attached Figure Description

Detailed Implementation

[0016] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0017] It should be noted that many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0018] like Figures 1-5 As shown, the slope protection pile provided by this utility model includes a pile body 100, which is preferably formed by concrete pouring and curing. Figure 1As shown, mortises 210 and tenons 220 are respectively provided on the left and right sides of the pile body 100, with the mortises 210 and tenons 220 extending longitudinally along the height direction of the pile body 100. The cross-sections of the mortises 210 and tenons 220 have arc-shaped contours, with the central angle of the arc-shaped contours being greater than π. The mortise 210 has a side insertion opening 201 on the left side of the pile body 100, and the mortise 210 has an end insertion opening 202 on the upper or lower end face of the pile body 100.

[0019] like Figure 6 As shown, during construction, the tenon 220 on one pile 100 is moved along the height direction of the pile 100 and inserted into the mortise 210 on the other pile 100. This allows the two piles 100 to be assembled and connected through the insertion and insertion of the tenon 220 and the mortise 210, forming a unified slope protection pile. The central angle of the arc-shaped profile of the mortise 210 and the tenon 220 is greater than π, so when the pile 100 is subjected to horizontal force, the tenon 220 will not dislodge from the mortise 210, resulting in a self-locking connection between the piles 100. More importantly, the arc-shaped profile of the tenon 220 and the mortise 210 allows them to rotate relative to each other around a center, enabling the slope protection pile to rotate arbitrarily around the tenon and mortise joint. This allows adjustment of the splicing angle between adjacent piles 100, making the slope protection pile adaptable to different types of curvature in engineering projects. Specifically, as shown... Figure 9 As shown in the figure, the slope protection pile provided by this utility model can be applied to the inner arc surface engineering type shown in part D, as well as the outer arc surface engineering type shown in part E, and has a wide range of applications.

[0020] Typically, the end slot 202 of the mortise 210 is positioned on the upper end face of the pile body 100, and the lower end of the mortise 210 is closed. During construction, the lower end of the tenon 220 on the pile body 100 to be installed is aligned with the upper end of the mortise 210 on the already installed pile body 100, and the pile body 100 to be installed is driven into the pile according to the construction requirements. After the installed pile body 100 has sunk to the specified position, the lower end of the tenon 220 abuts against the bottom of the mortise 210.

[0021] In one specific embodiment, the mortise 210 is formed by an inner nested tube 211 embedded in the pile body 100, and the tenon 220 is formed by an outer protruding sleeve 221 fixedly connected to the right side of the pile body 100. Using this method, the mortise and tenon are easy to process, and their dimensions are accurately controlled.

[0022] Specifically, a first side plate 212 is provided on both sides of the side opening of the inner nested tube 211, with the left side of the first side plate 212 flush with the left side of the pile body 100. A second side plate 222 is fixed to the left side of the outer protruding sleeve 221, extending from the right side of the pile body 100. That is, connecting the outer protruding sleeve 221 and the inner nested tube 211 to the pile body 100 through a neck section not only ensures that the concrete thickness at the side opening of the inner nested tube 211 meets the requirements, but also facilitates the insertion process of the tenon 220 and the mortise 210, and allows for relative rotation between the tenon 220 and the mortise 210, enabling adjustment of the splicing angle between two adjacent pile bodies 100.

[0023] Furthermore, after the pile body 100 is assembled on the engineering slope, grouting material can be filled into the outward protruding sleeve 221. After the grouting material solidifies, it forms a seal on the outward protruding sleeve 221.

[0024] Furthermore, the outer convex sleeve 221 and the inner nested pipe 211 are each composed of several pipe segments spaced apart along the height direction of the pile body 100. Compared with a single pipe structure, the multi-segment design can save raw materials and reduce frictional resistance during assembly. On the other hand, it can meet the requirements of the following situations: For example, when repairing a river channel, the slope protection piles are allowed to seep water within a required range to maintain ecological balance. In this case, water can seep through the splicing joints between the pile bodies 100 and the areas between the pipe segments. When the river channel is used for irrigation or to achieve pressure relief and drainage functions, the slope protection piles are required to be watertight. In this case, grout can be injected into the outer convex sleeve 221 after the pile bodies 100 are spliced. The grout can flow to the areas between the pipe segments. After the grout has solidified, it can tightly connect the tenon 220, the mortise 210, and the pile body 100 to prevent water seepage.

[0025] like Figure 7 and Figure 8 As shown, to improve the strength of the slope protection piles, a reinforcing cage 300 is embedded inside the pile body 100 and the side piles 400. Furthermore, the tenon 220 (outer protruding sleeve 221) and the mortise 210 (inner nested tube 211) are both fixedly connected to the reinforcing cage 300, so that when the slope protection piles are spliced ​​together, the tenon 220, the mortise 210, and the pile body 100 form an integral force-bearing structure with high tensile strength. Specifically, a through hole can be opened in the second side plate 222 to connect the second side plate 222 to the reinforcing cage 300.

[0026] In a preferred embodiment, a side pile 400 is provided on the rear side of the pile body 100. The side pile 400 extends along the height direction of the pile body 100, and the cross-sectional contours of the side pile 400 and the pile body 100 form a T-shaped structure. The design of the side pile 400 increases the outer surface area of ​​the slope protection pile, thereby increasing the friction between the slope protection pile and the soil and improving the stability of the slope protection pile in the soil. Furthermore, the side pile 400 significantly increases the section bending modulus of the slope protection pile, enhancing its soil and water retention capacity. Further, the connection between the side pile 400 and the pile body 100 has a chamfered structure, forming a haunch beam structure, which saves materials while ensuring the connection strength between the side pile and the pile body.

[0027] In addition, the slope protection piles provided by this utility model can also be applied to retaining walls. During installation, the side piles should be separated from the soil. The introduction of side piles can significantly improve the stability of the slope protection piles.

[0028] Preferably, the lower ends of the pile body 100 and the side piles 400 are designed with pointed shapes to facilitate pile driving construction.

[0029] In one specific embodiment, the reinforcing cage 300 can be formed by binding and welding multiple layers of T-shaped frames and vertical bars. Each segment constituting the outer convex sleeve 221 and the inner nested tube 211 is fixed to the T-shaped frame, and the T-shaped frames are connected by vertical bars to form the reinforcing cage 300. A formwork is then erected on the outside of the reinforcing cage 300, concrete is poured, and after curing, it becomes a slope protection pile.
