Abstract
Description
Technical Field
[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a river embankment reinforcement structure. Background Technology
[0002] In the field of water conservancy engineering construction, traditional river embankment structures mostly adopt the stone-building technique. The stones on the surface of the embankment are simply piled together, relying solely on their own weight and the friction between the stones for restraint. This method of stacking is unreliable, and the connection between the stones is weak. Under the action of water flow erosion or other external forces, the stones are prone to displacement due to local stress concentration; the stones can easily loosen and collapse, thus creating certain safety hazards. Summary of the Invention
[0003] The purpose of this invention is to address the shortcomings of existing technologies and provide a riverbank reinforcement structure.
[0004] The purpose of this utility model is achieved through the following technical solution: a riverbank reinforcement structure, characterized in that it includes a central body, on which a plurality of telescopic and adjustable connecting arms are provided, an anchor pipe is provided at one end of the connecting arm, and a core rod is provided in the anchor pipe; the anchor pipe includes an upper pipe body and an expansion pipe body located at the lower end of the upper pipe body, and an expansion mechanism is provided between the expansion pipe body and the core rod; in the installed state, the anchor pipe is inserted into the anchor hole on the riverbank stone, and the expansion pipe body expands outward under the action of the expansion mechanism and presses against the hole wall of the anchor hole.
[0005] Preferably, the connecting arm includes an outer tube and an inner telescopic rod, with the outer tube and the inner telescopic rod slidingly engaged, and the outer tube is provided with a locking screw for locking the inner telescopic rod.
[0006] Preferably, the expansion tube includes a plurality of expansion petals arranged in a circular array, with expansion slots provided between the expansion petals; the expansion mechanism includes a spherical groove disposed on the inner side of the expansion tube and a spherical body disposed on the outer side of the core rod and cooperating with the spherical groove.
[0007] Preferably, the core rod is provided with a grouting channel.
[0008] Preferably, the upper end of the anchor tube is provided with a nut, and the core rod is provided with an external thread that mates with the nut; the upper end of the core rod is provided with a screwing part.
[0009] Preferably, the rotating part is a regular hexagon.
[0010] Preferably, the central body is provided with four connecting arms.
[0011] The beneficial effects of this utility model are as follows: During installation, anchor holes are first drilled in the riverbank stones. Then, this device is placed in the middle of several adjacent riverbank stones, and the anchor pipes are inserted into the anchor holes on the riverbank stones respectively. Then, the expansion mechanism is triggered by the core rod, causing the expansion tube to expand outward and tightly press against the anchor hole wall, so that the expansion tube and the anchor hole have an interference fit, firmly locking the anchor pipe to the individual riverbank stone and preventing the anchor pipe from loosening in the anchor hole. The single central body connects multiple adjacent stones through multiple connecting arms, which is equivalent to establishing a rigid connecting bridge between the dispersed riverbank stones. This transforms the traditional individual force-bearing mode of riverbank stones into a collaborative force-bearing mode of multiple riverbank stones, improves the connection between adjacent stones, enhances the integrity of the riverbank stones, effectively disperses local stress, prevents displacement of a single stone due to stress concentration, fundamentally reduces the risk of stone loosening and collapse, and significantly improves the overall resistance to damage of the riverbank structure.

[0017] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.
[0018] like Figures 1 to 4As shown, a riverbank reinforcement structure includes a central body 1, on which several telescopic and adjustable connecting arms 2 are provided. An anchor pipe 3 is provided at one end of the connecting arm 2, and a core rod 4 is provided in the anchor pipe 3. The anchor pipe 3 includes an upper pipe body 3-1 and an expansion pipe body located at the lower end of the upper pipe body 3-1. An expansion mechanism is provided between the expansion pipe body and the core rod 4. In the installed state, the anchor pipe 3 is inserted into the anchor hole on the riverbank stone block 5, and the expansion pipe body expands outward under the action of the expansion mechanism and presses against the hole wall of the anchor hole.
[0019] During installation, anchor holes are first drilled in the riverbank stones 5. The device is then placed between several adjacent riverbank stones 5, and anchor pipes 3 are inserted into the anchor holes on each stone 5. The expansion mechanism is then triggered by the core rod 4, causing the expansion tube to expand outwards and tightly press against the anchor hole wall, creating an interference fit between the expansion tube and the anchor hole. This securely locks the anchor pipe 3 to each individual riverbank stone 5, preventing it from loosening within the anchor hole. A single central body 1 connects multiple adjacent stones via multiple connecting arms 2, effectively establishing a rigid bridge between the dispersed riverbank stones 5. This transforms the traditional individual stress pattern of riverbank stones 5 into a collaborative stress pattern among multiple stones, improving the connection between adjacent stones, enhancing the overall integrity of the riverbank stone structure, effectively dispersing local stress, preventing displacement of individual stones due to stress concentration, fundamentally reducing the risk of stone loosening and collapse, and significantly improving the overall resistance to damage to the riverbank structure.
[0020] The connecting arm 2 can flexibly adjust its length according to the actual spacing and positional deviation of adjacent riverbank stones 5, without the need for uniform size processing or precise positioning of the stones, thus adapting to riverbank scenarios with different specifications and stacking gaps. Even if the riverbank stones 5 have certain irregular shapes, the telescopic adjustment capability of the connecting arm 2 can compensate for the positional deviation between the stones, ensuring the effective connection between the anchor pipe 3 and the riverbank stones 5.
[0021] The connecting arm 2 includes an outer sleeve 2-1 and an inner telescopic rod 2-2. The outer sleeve 2-1 and the inner telescopic rod 2-2 are slidably fitted together. The outer sleeve 2-1 is provided with a locking screw 2-3 for locking the inner telescopic rod 2-2. When adjusting the length of the connecting arm 2, first loosen the locking screw 2-3, then adjust the connecting arm 2 to the required length, and finally tighten the locking screw 2-3.
[0022] The expansion tube body includes several expansion petals 3-2 arranged in a circular array, with expansion joints 3-3 between the expansion petals 3-2. The expansion mechanism includes a spherical groove 3-4 located inside the expansion tube body and a spherical body 4-1 located outside the core rod 4 and cooperating with the spherical groove 3-4. Before the anchor tube 3 is inserted into the anchor hole on the riverbank stone 5, the spherical body 4-1 on the core rod 4 is embedded in the spherical groove 3-4 inside the expansion tube body, and the spherical body 4-1 outside the core rod 4 and the spherical groove 3-4 inside the expansion tube body have a curved surface fit. When the core rod 4 is pushed to move along the axial direction of the anchor tube 3, the spherical body 4-1 will tend to disengage from the spherical groove 3-4. During this process, the spherical body 4-1 will generate an outward "expanding force" on the expansion tube body, causing all the expansion petals 3-2 to expand outward, thereby tightening the expansion tube body and the anchor tube 3 hole wall, ultimately achieving an "interference fit" between the anchor tube 3 and the anchor hole, and improving the connection strength of the anchor tube 3.
[0023] The upper end of the anchor pipe 3 is provided with a nut 3-5, and the core rod 4 is provided with an external thread that mates with the nut 3-5; the upper end of the core rod 4 is provided with a tightening part 4-3. The nut 3-5 is welded and fixed to the upper end of the anchor pipe 3, and the core rod 4 and the nut 3-5 are threadedly engaged. By rotating the tightening part 4-3 at the upper end of the core rod 4, the core rod 4 rotates synchronously, and under the action of the threaded engagement, the core rod 4 moves axially along the anchor pipe 3.
[0024] In this embodiment, the rotating part 4-3 is a regular hexagon. The rotating part 4-3 can be used with a wrench or the like to rotate the core rod 4.
[0025] The core rod 4 is equipped with a grouting channel 4-2. After the anchor pipe 3 is installed into the anchor hole of the riverbank stone 5, grout can be injected into the anchor hole of the riverbank stone 5 through the grouting channel 4-2, so that the anchor hole is filled with concrete grout, thereby improving the fixing effect of the anchor pipe 3.
[0026] In this embodiment, the central body 1 is provided with four connecting arms 2. This device can be connected to four adjacent riverbank stones 5 at the same time, thereby establishing a rigid connection between these four adjacent riverbank stones 5.
[0027] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
