Description

Technical Field

[0001] This utility model belongs to the field of bank protection sheet pile technology, specifically relating to a telescopic bank protection sheet pile. Background Technology

[0002] Sheet piles are structural components used to protect riverbanks, coastlines, lake shores, and other waterfront areas, preventing soil erosion, water flow scouring, and soil collapse. They are typically inserted into the soil along the bank, with the upper part extending above the water surface, forming a continuous or intermittent protective structure to resist the effects of external forces such as water flow and waves.

[0003] For example, Chinese utility model patent with patent number ZL201821850244.9 discloses an eco-friendly high-strength revetment sheet pile with a flower basket, including an eco-sheet pile 1. A rigid protrusion 2 is fixedly installed on the upper end of the eco-sheet pile 1. A first connector 3 is fixedly connected to the right end of the eco-sheet pile 1. A second connector 4 is fixedly installed on the left end of the eco-sheet pile 1. An eco-basket 5 is movably installed on the outside of the first connector 3. A water-permeable hole 6 is reserved at the back of the eco-basket 5. A reserved groove 7 is provided on the bottom of the eco-basket 5. Compared to previous revetment sheet piles, this eco-friendly, high-strength revetment sheet pile with a flower basket features a rigid protrusion as an accessory. The semi-circular design of the rigid protrusion enhances the vibration resistance of the eco-sheet pile, improving its stability. The trapezoidal design of the eco-basket, with a height of 8-25mm, facilitates interlocking with the recessed areas of the eco-sheet pile, ensuring its stability. The eco-basket and the first connector are snap-fitted together, facilitating easy assembly and disassembly. Furthermore, permeable holes, with a diameter of 8-20mm, are evenly spaced at the bottom of the eco-basket and the side furthest from the pre-reserved groove, allowing for the planting of floating plants, which helps improve water quality, beautify the environment, and optimize the aquatic ecosystem.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model relates to a telescopic revetment sheet pile. Figures 1-3The first embodiment of this utility model is shown, which includes a first sheet pile 1 that can be spliced ​​together, and a second sheet pile 2 that is adapted to the shape of the first sheet pile 1 and is stacked and fitted together. An adjustment mechanism 3 is also provided between the first sheet pile 1 and the second sheet pile 2, which can drive the second sheet pile 2 to slide and extend along the height direction of the first sheet pile 1. The adjustment mechanism 3 includes a positioning block 31 and a positioning block 32 that are arranged opposite to each other and respectively installed on the surfaces of the first sheet pile 1 and the second sheet pile 2, and a lead rod 33 that is threaded through the positioning block 32 and rotatably connected to the positioning block 31 at one end. A screwing part 34 is also provided at the other end of the lead rod 33 away from the positioning block 31. The screwing part 34 is configured to drive the lead rod 33 to rotate along its axis under the action of external force. In this embodiment, the screwing part 34 is a regular hexagon, which can be rotated by a wrench or other electric or pneumatic screwing tools. In addition to a regular hexagon, the screwing part 34 can also be other polygonal structures, or common slots such as straight slots, cross slots, and hexagonal slots, etc., which are not limited here.

[0029] In practical use, a screw-tightening tool is used in conjunction with the screw-tightening part 34 to drive the screw-tightening part 34 to rotate. This causes the screw-tightening part 34 to rotate the lead screw 33. Through the threaded engagement between the screw-tightening part 34 and the positioning block 32, the second sheet pile 2 slides and extends along the height direction of the first sheet pile 1, thereby offsetting it from the first sheet pile 1 and increasing the revetment height of the first sheet pile 1. It should be noted that the height direction of the first sheet pile 1 is its installation direction when it is inserted into the soil on the bank.

[0030] In order not to affect the installation stability of the first sheet pile 1, the height of the second sheet pile 2 should be less than the height of the first sheet pile 1. Specifically, it is preferably one-half or one-third of the height of the first sheet pile 1, so as to ensure that the empty part at the bottom of the first sheet pile 1 can be inserted into the soil.

[0031] To facilitate the splicing of the first sheet piles 1, such as Figure 3 As shown, a first connector 11 is provided at one end of the first sheet pile 1, and a second connector 12 that can be engaged with the first connector 11 is provided at the other end of the first sheet pile 1. In this embodiment, the first connector 11 is "C" shaped and the second connector 12 is "G" shaped. The first sheet piles 1 are spliced ​​together by engaging with each other. At the same time, the second connector 12 is also provided with a engaging part 121 for engaging the ecological basket. The splicing and specific installation structure and principle of the ecological basket are the same as those of the Chinese utility model patent with patent number ZL201821850244.9 proposed in the background art, and will not be described again here.

[0032] Figures 4-5A second embodiment of the present invention is shown, which differs from the first embodiment in that a guide assembly is further provided between the first sheet pile 1 and the second sheet pile 2. The guide assembly includes a groove 4 that is formed opposite to the surface of the first sheet pile 1 and extends along the height direction of the first sheet pile 1, and a slider 5 that is formed opposite to the surface of the second sheet pile 2 and constrained and engaged with the groove 4. In this example, the groove 4 is trapezoidal, but it can also be any other shape that can constrain the slider 5 so that it does not disengage from the extension direction of the groove 4.

[0033] In use, due to the setting of the guide component, not only can the second sheet pile 2 slide stably along the height direction of the first sheet pile 1, but also the radial compressive strength of the second sheet pile 2 can be improved due to the constraint between the slide groove 4 and the slider 5.

[0034] Figure 6 This illustration shows a third embodiment of the present invention, which differs from the first and second embodiments in that: rigid protrusions 6 extending along the height direction are spaced apart on the surface of the first sheet pile 1. The rigid protrusions 6 are semi-circular in design, which helps to enhance the strength of the first sheet pile 1 and ensure the service life of the device. In this embodiment, the rigid protrusions 6 are located at the middle position of each plate surface of the first sheet pile 1, and at the connecting and turning positions between the plate surfaces.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
