Description

Sheet pile locking with self-sealing rubber insert Technical Field

[0001] This utility model relates to the field of sheet pile locking technology, specifically a sheet pile locking mechanism with a self-sealing rubber insert. Background Technology

[0002] In building construction, especially in water conservancy, transportation and various underground projects, steel sheet piles are widely used as an important retaining structure. During the use of steel sheet piles, locking mechanisms are required.

[0003] Patent CN220503875U discloses a latch, which includes a vertical part, a horizontal part, and a bent part. One end of the horizontal part is fixedly connected to one end of the vertical part, and the angle between the horizontal part and the vertical part is a right angle. One end of the bent part is fixedly connected to the end of the horizontal part away from the vertical part, and the other end of the bent part is bent toward the horizontal part.

[0004] While this device solves the technical problem that existing hot-rolled sheet pile interlocks are unsuitable for connecting cold-formed sheet piles, it has limitations in terms of sealing and waterproofing performance and length adjustment. The device lacks a self-sealing rubber strip, making it difficult to eliminate gaps after the interlock connection. During water-blocking operations, moisture easily seeps through these gaps, and traditional interlocks cannot effectively prevent water leakage, leading to water accumulation in the foundation pit. This not only affects construction progress but may also cause safety hazards such as soil collapse due to waterlogging. Furthermore, while the device's overall length is adjustable, its fixed length makes it difficult to adapt flexibly. During construction, additional secondary processing such as cutting and welding of the sheet piles is often required, which is not only labor-intensive and resource-intensive but also makes it difficult to guarantee the connection strength and sealing of the interlocks after processing, resulting in inconsistent project quality. Therefore, we propose a sheet pile interlock with a self-sealing rubber strip. Summary of the Invention

[0005] The purpose of this invention is to provide a sheet pile locking device with a self-sealing rubber insert. By setting a sealing groove and a sealing strip, the problem of water seepage at the connection of the sheet pile locking device is solved, and the water-stopping performance is enhanced. By setting an adjustable length female buckle and an adjustment mechanism, the problem that traditional locking devices cannot adapt to different construction scenarios is solved, ensuring that the sheet piles are tightly connected in various projects.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A sheet pile locking mechanism with a self-sealing rubber insert includes a female locking mechanism and a male locking mechanism. The female locking mechanism includes a female locking head with a wedge-shaped groove on its top surface, a sleeve located on the left side of the female locking head, and a telescopic rod fixed to the left surface of the female locking head and slidably inserted into the sleeve. The male locking mechanism includes a male locking mechanism slidably inserted into the wedge-shaped groove on the top surface of the female locking head, and a sealing strip fixed to the outer wall of the male locking mechanism for sealing. The mechanism also includes:

[0008] An adjustment mechanism is provided on the top surface of the sleeve for adjusting the overall length of the female buckle. The adjustment mechanism includes a limiting plate and a mounting plate fixed on the top surface of the sleeve, a moving rod slidably connected to the top surface of the sleeve, a connecting rod fixed between the moving rod and the telescopic rod, and a screw rotatably connected between the limiting plate and the mounting plate for driving the moving rod to move left and right. The left side of the limiting plate is provided with a turntable for driving the screw and limiting its movement.

[0009] In a preferred embodiment, the inner walls of both the front and rear sides of the sleeve are provided with sliding grooves, and the front and rear surfaces of the telescopic rod are fixed with sliding strips that are slidably connected to the sliding grooves on the same side of the inner wall of the sleeve near the left end.

[0010] In a preferred embodiment, the top surface of the female buckle head is provided with a sealing groove that communicates with the wedge-shaped groove on its top surface. The male buckle head also includes a fixing rod fixed on the right side surface of the male buckle head. The shape of the male buckle head is adapted to the shape of the wedge-shaped groove on the top surface of the female buckle head. The sealing strip corresponds to the position of the sealing groove on the top surface of the female buckle head, and the outline dimension of the sealing strip is slightly larger than the inner outline dimension of the sealing groove on the top surface of the female buckle head.

[0011] These two features enable the sheet pile interlocking system to be both tightly connected and have good sealing and waterproofing performance. When the male and female interlocking are connected, the sealing strip can better fill the gaps, enhance the water-stopping effect, and make the length adjustment of the female interlocking more convenient and the structure more stable.

[0012] In a preferred embodiment, the limiting plate and the mounting plate are respectively fixed on the top surface of the sleeve near the left and right ends. The adjustment mechanism also includes two rotating columns that are rotatably connected to the limiting plate and the mounting plate respectively, a rotating rod that is coaxially fixed on the left side surface of the left rotating column, the turntable that is coaxially fixed on the left outer wall of the rotating rod, and the screw that is coaxially fixed between the two rotating columns and is threadedly connected to the moving rod.

[0013] In a preferred embodiment, the movable rod is L-shaped, the connecting rod is fixed between the bottom surface of the horizontal plate end of the movable rod and the top surface of the telescopic rod, the top surface of the sleeve is provided with a guide groove arranged horizontally, and the bottom surface of the vertical rod end of the movable rod is fixed with a guide block that is slidably connected to the guide groove on the top surface of the sleeve.

[0014] In a preferred embodiment, the longitudinal cross-sectional shape of the guide groove on the top surface of the sleeve is convex, and the shape of the guide block is convex, which matches the shape of the guide groove on the top surface of the sleeve.

[0015] In a preferred embodiment, when the vertical plate end of the movable rod is located near the left end of the outer wall of the screw circumference, the left end face of the telescopic rod is located near the left end inside the sleeve.

[0016] In a preferred embodiment, the adjusting mechanism further includes a bolt located above the sleeve. The left side surface of the limiting plate is provided with a plurality of threaded holes distributed in a ring at equal intervals. The left side surface of the turntable is provided with a plurality of through holes arranged in a ring at equal intervals. The plurality of through holes on the left side surface of the turntable are all corresponding to the threaded holes on the same side of the outer wall of the left side of the limiting plate and are adapted in size. The shank of the bolt passes through the through holes on the same side of the outer wall of the turntable and is threadedly connected to the threaded holes on the same side of the outer wall of the limiting plate.

[0017] These five features improve the guiding properties of the moving rod, ensuring the accuracy of length adjustment of the telescopic rod, preventing the guide block from easily dislodging when sliding in the guide groove, further enhancing the stability of the moving rod, enabling the telescopic rod to achieve a wider range of extension and retraction within the sleeve, meeting more length adjustment needs, and ensuring that the screw can be effectively fixed after being adjusted to the appropriate position, guaranteeing the stability of the length after the female thread is adjusted.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model, by setting a wedge-shaped groove on the top surface of the female buckle head that matches the shape of the male buckle head, and fixing a sealing strip on the male buckle head that corresponds to the sealing groove position of the female buckle head, and setting the outline size of the sealing strip to be slightly larger than the inner outline size of the sealing groove, achieves that when the male buckle and female buckle are connected, the sealing strip can tightly fill the sealing groove of the female buckle head, effectively preventing water from seeping through the gaps at the connection of the steel sheet pile buckle, and achieving a significant improvement in water-stopping performance compared to traditional steel sheet pile buckles, which can meet the water-stopping needs of engineering scenarios with high waterproofing requirements, such as underground buildings and water conservancy projects;

[0020] 2. This utility model, by setting an adjustment mechanism on the top surface of the sleeve, includes components such as a limiting plate, a mounting plate, a moving rod, a connecting rod, a screw, and a turntable. This allows for flexible adjustment of the overall length of the female thread by rotating the turntable to drive the screw to rotate, which in turn drives the moving rod to move left and right. The moving rod, through the connecting rod, drives the telescopic rod to extend and retract within the sleeve. This achieves the goal of ensuring a tight connection between sheet piles according to different construction scenarios and needs, whether it's irregularly shaped foundation pit support or cofferdam projects of varying depths. It improves the versatility and construction efficiency of the threaded connection, and reduces construction difficulties and increased time costs caused by mismatched threaded connection lengths.

[0021] 3. By combining the above-mentioned sealing structure with the adjustable length structure, this utility model achieves the dual advantages of improving water-stopping performance and enhancing the adaptability of the locking buckle to different construction scenarios. This enables better quality assurance in various projects, reduces potential engineering hazards caused by leakage and locking buckle connection problems, and expands the application range of steel sheet pile locking buckles, providing a more reliable and efficient solution for engineering construction.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0030] Please refer to Figures 1-3 and 5. The present invention provides a technical solution: a steel sheet pile lock with a self-sealing rubber insert, including a female lock 1 and a male lock 2. The female lock 1 includes a female lock head 11 with a wedge-shaped groove on its top surface, a sleeve 12 located on the left side of the female lock head 11, and a telescopic rod 13 fixed on the left side surface of the female lock head 11 and slidably inserted into the sleeve 12. The male lock 2 includes a male lock 2 slidably inserted into the wedge-shaped groove on the top surface of the female lock head 11, and a sealing strip 23 fixed on the outer wall of the male lock 2 for sealing.

[0031] The inner walls of the front and rear sides of the sleeve 12 are provided with sliding grooves, and the front and rear sides of the telescopic rod 13 are fixed with sliding strips 14 that are slidably connected to the sliding grooves on the same side of the inner wall of the sleeve 12 near the left end.

[0032] The top surface of the female buckle 11 is provided with a sealing groove that communicates with the wedge-shaped groove on its top surface. The male buckle 2 also includes a fixing rod 21 fixed on the right side surface of the male buckle 22. The shape of the male buckle 22 is adapted to the shape of the wedge-shaped groove on the top surface of the female buckle 11. The sealing strip 23 corresponds to the position of the sealing groove on the top surface of the female buckle 11, and the outline dimension of the sealing strip 23 is slightly larger than the inner outline dimension of the sealing groove on the top surface of the female buckle 11.

[0033] By using the inner wall groove of sleeve 12 and the sliding strip 14 of telescopic rod 13 to make the telescopic rod 13 slide inside sleeve 12, the groove plays a limiting and guiding role on the sliding strip 14, preventing the telescopic rod 13 from shaking or deviating, ensuring its smooth sliding process, and enhancing the stability of the connection between telescopic rod 13 and sleeve 12.

[0034] Through the design of the sealing groove of the female buckle 11, the fixing rod 21 of the male buckle 22 and the sealing strip 23, the fixing rod 21 assists in positioning when the male buckle is connected to the female buckle. The sealing strip 23 is squeezed and deformed due to its slightly larger size, which tightly fills the gap, effectively prevents water penetration and significantly improves the water-stopping performance of the steel sheet pile lock.

[0035] In this embodiment, as shown in Figures 1-2 and 4, it further includes: an adjustment mechanism 15, which is disposed on the top surface of the sleeve 12 and is used to adjust the overall length of the female buckle 1. The adjustment mechanism 15 includes a limiting plate 151 and a mounting plate 152 fixed on the top surface of the sleeve 12, a moving rod 155 slidably connected to the top surface of the sleeve 12, a connecting rod 156 fixed between the moving rod 155 and the telescopic rod 13, and a screw 154 rotatably connected between the limiting plate 151 and the mounting plate 152 and used to drive the moving rod 155 to move left and right. The left side of the limiting plate 151 is provided with a turntable 159 for driving the screw 154 and limiting it.

[0036] The limiting plate 151 and the mounting plate 152 are respectively fixed on the top surface of the sleeve 12 near the left and right ends. The adjusting mechanism 15 also includes two rotating columns 153 that are rotatably connected to the limiting plate 151 and the mounting plate 152 respectively, a rotating rod 158 coaxially fixed on the left side surface of the left rotating column 153, a turntable 159 coaxially fixed on the left outer wall of the rotating rod 158, and a screw 154 coaxially fixed between the two rotating columns 153, and the screw 154 is threadedly connected to the moving rod 155.

[0037] The movable rod 155 is L-shaped. The connecting rod 156 is fixed between the bottom surface of the horizontal plate end of the movable rod 155 and the top surface of the telescopic rod 13. The top surface of the sleeve 12 is provided with a guide groove arranged horizontally, and the bottom surface of the vertical rod end of the movable rod 155 is fixed with a guide block 157 that is slidably connected to the guide groove on the top surface of the sleeve 12.

[0038] The longitudinal cross-sectional shape of the guide groove on the top surface of the sleeve 12 is convex, and the shape of the guide block 157 is convex, which matches the shape of the guide groove on the top surface of the sleeve 12.

[0039] When the vertical plate end of the moving rod 155 is located near the left end of the outer circumference of the screw 154, the left end face of the telescopic rod 13 is located near the left end inside the sleeve 12.

[0040] The adjusting mechanism 15 also includes a bolt 1510 located above the sleeve 12. The left side surface of the limiting plate 151 is provided with a number of threaded holes distributed in a ring at equal intervals. The left side surface of the turntable 159 is provided with a number of through holes arranged in a ring at equal intervals. The number of through holes on the left side surface of the turntable 159 corresponds to the position and size of the threaded holes on the same side of the left outer wall of the limiting plate 151. The rod of the bolt 1510 passes through the through hole on the same side of the outer wall of the turntable 159 and is threadedly connected to the threaded hole on the same side of the outer wall of the limiting plate 151.

[0041] The adjustment mechanism 15 is composed of components such as the limiting plate 151, the mounting plate 152, the rotating column 153, and the screw 154. Rotating the turntable 159 drives the screw 154 to rotate, which in turn drives the moving rod 155 to move, thereby realizing the adjustment of the length of the female buckle 1. The components work together, making the operation convenient and the structure stable, ensuring the reliability of the adjustment process.

[0042] Through the L-shaped design of the moving rod 155, the connecting rod 156, and the cooperation of the guide groove and guide block 157, the L-shaped moving rod 155 is easy to connect with the telescopic rod 13 and the screw 154. The guide groove and guide block 157 restrict the moving direction of the moving rod 155 to ensure its precise movement, thereby driving the telescopic rod 13 to precisely adjust the length of the female buckle 1.

[0043] Through the U-shaped guide groove on the top surface of the sleeve 12 and the matching U-shaped guide block 157, the unique U-shaped structure enables the guide block 157 to form a locking limit when sliding in the guide groove, effectively preventing the guide block 157 from coming out, further enhancing the stability of the moving rod 155 when moving, and ensuring the reliability of the length adjustment of the female buckle 1.

[0044] By setting the positional relationship between the movable rod 155 and the telescopic rod 13, when the movable rod 155 is located at a specific position of the screw 154, the telescopic rod 13 is located at the corresponding position inside the sleeve 12. This design expands the telescopic range of the telescopic rod 13 inside the sleeve 12, which can meet the needs of adjusting the length of the female buckle 1 in more different construction scenarios.

[0045] With the setting of the threaded hole of the limiting plate 151, the through hole of the turntable 159 and the bolt 1510, after the length of the female buckle 1 is adjusted, the bolt 1510 is screwed into the threaded hole of the limiting plate 151 through the through hole of the turntable 159. This can fix the turntable 159 and the screw 154, prevent them from rotating at will, ensure the stability of the length of the female buckle 1 after adjustment, and ensure the reliable connection of the steel sheet pile.

[0046] In this embodiment, the sealing principle is as follows: When the male buckle 2 is connected to the female buckle 1, the male buckle head 22 can be inserted into the wedge-shaped groove on the top surface of the female buckle head 11 because its shape is adapted to the wedge-shaped groove on the top surface of the female buckle head 11. At the same time, the fixing rod 21 assists in positioning. The sealing strip 23, because its outline size is larger than the sealing groove of the female buckle head 11, is squeezed and deformed to fill the gap, prevent water penetration, and achieve a good water-stopping effect.

[0047] Length adjustment principle: Rotating the turntable 159 drives the rotating rod 158 and rotating column 153 to rotate, causing the screw 154 to rotate. The screw 154 is threadedly engaged with the moving rod 155, driving the L-shaped moving rod 155 to slide along the guide groove on the top surface of the sleeve 12. The guide block 157 ensures accurate movement direction. The moving rod 155 drives the telescopic rod 13 to extend and retract within the sleeve 12 through the connecting rod 156, realizing the length adjustment of the female thread 1. After adjustment, the bolt 1510 is passed through the through hole of the turntable 159 and screwed into the threaded hole of the limiting plate 151 to fix the screw 154, ensuring the stability of the length of the female thread 1 and meeting the connection requirements of steel sheet piles in different construction scenarios.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
