Description

Technical Field

[0001] This utility model relates to the field of Larssen sheet pile support technology, specifically a Larssen sheet pile installation guide and positioning auxiliary device. Background Technology

[0002] Larssen sheet piles are a type of special steel component widely used in civil engineering, mainly for constructing temporary or permanent retaining walls, cofferdams, breakwaters, foundation pit support, and other structures.

[0003] For the construction of Larssen sheet piles, the traditional construction method is to interlock the edges of two adjacent "W"-shaped sheet piles to form a continuous steel anti-seepage support wall.

[0004] The traditional Larssen sheet pile construction method has the following problems in actual construction: 1) Due to the influence of factors such as terrain and environment, gaps are easily generated at the joints between Larssen sheet piles under the traditional construction method, which can lead to soil erosion; 2) The lateral stiffness of Larssen sheet piles under the traditional construction method is relatively small, and they are prone to deformation; 3) The straightness of Larssen sheet piles under the traditional construction method cannot be guaranteed, which reduces the construction quality and forming efficiency of Larssen sheet piles. Summary of the Invention

[0005] The purpose of this invention is to solve the problems mentioned in the background art by providing a Larssen sheet pile installation guidance and positioning auxiliary device.

[0006] This utility model is achieved through the following technical solution:

[0007] A Larssen sheet pile installation guidance and positioning auxiliary device includes an A-type clamp, a B-type clamp, fasteners, fixed piles, a Larssen sheet pile body, and pile holes. The A-type clamp and the B-type clamp are cut from steel plates with a thickness of 50mm. The edges of the A-type clamp and the B-type clamp are serrated. The A-type clamp and the B-type clamp are of equal length. After the serrated edges of the A-type clamp and the B-type clamp are aligned and spliced, they can vertically pass through the Larssen sheet pile body. Pile holes are opened at both ends of the A-type clamp and the B-type clamp. Each fixed pile passes through one pile hole and is fixed to the ground. The fasteners are fixedly installed on the A-type clamp and the B-type clamp and are located on both sides of the recessed part of the Larssen sheet pile body.

[0008] Preferably, the type A card 1 and type B card 2 are cut from steel plates with a thickness of 50mm.

[0009] Preferably, the A-type card plate and the B-type card plate are provided with lifting rings, which are fixedly installed on the opposite side of the serrated edge of the A-type card plate and the B-type card plate.

[0010] Preferably, the fastener includes a rectangular steel component, a fastening plate, a threaded cylinder, and a rotating handle. The rectangular steel component is fixedly installed on a type A clamping plate and a type B clamping plate. A rotating handle is fixedly installed at one end of the threaded cylinder, and a fastening plate is installed at the other end of the threaded cylinder. The threaded cylinder is screwed through the rectangular steel component by threads.

[0011] Preferably, the thickness of the steel plate within a 280mm range on the left side of the Type A and Type B card plates decreases downward to 25mm, and the thickness of the steel plate within a 280mm range on the right side of the Type A and Type B card plates decreases upward to 25mm.

[0012] This utility model provides a Larssen sheet pile installation guidance and positioning auxiliary device. Through its structural design, during construction, individual A-type and B-type clamps (each A-type and B-type clamp refers to a corresponding A-type clamp and a corresponding B-type clamp) are first fixed to the soil on both sides of the longitudinal direction of the Larssen sheet pile support wall using fixing piles. During construction, the Larssen sheet pile body passes through the hole formed by the combined A-type and B-type clamps and is pressed down, achieving longitudinal vertical control of the Larssen sheet pile body. The Larssen sheet pile bodies at both ends of each clamp are constructed first, followed by the Larssen sheet pile bodies in the middle of each clamp. When each Larssen sheet pile body is pressed down, the fasteners on both sides of the longitudinal direction of the Larssen sheet pile body can be adjusted at any time to control the lateral verticality of the Larssen sheet pile body. After the combined Type A and Type B clamps are inserted into the Larssen sheet pile body, another Type A and Type B clamp can be spliced ​​at the left or right end to continue driving the subsequent Larssen sheet pile bodies. After the previously constructed Larssen sheet pile bodies are completed, the Type A and Type B clamps can be removed for subsequent construction.

[0013] Compared to existing technologies, this invention provides a stable construction platform, simplifying the driving process of Larssen sheet piles. Guided by a guiding device, construction workers can more easily control the insertion position and angle of the Larssen sheet pile, helping to prevent deviation or toppling during driving and thus avoiding potential safety accidents. It can adapt to different geological conditions and be used for sheet pile construction in various complex geological environments. This invention offers advantages in terms of ease of construction and safety, accurate positioning, quality control, adaptability and flexibility, and economic benefits, helping to improve construction efficiency, ensure project quality, and reduce construction costs.

[0023] 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.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] like Figures 1 to 8As shown, this embodiment provides a Larssen sheet pile installation guidance and positioning auxiliary device, including an A-type clamping plate 1, a B-type clamping plate 2, a fastener 3, a fixing pile 4, a Larssen sheet pile body 5, and pile holes 6. The A-type clamping plate 1 and the B-type clamping plate 2 are cut from steel plates with a thickness of 50mm. The edges of the A-type clamping plate 1 and the B-type clamping plate 2 are serrated. The A-type clamping plate 1 and the B-type clamping plate 2 are of equal length. After the serrated edges of the A-type clamping plate 1 and the B-type clamping plate 2 are aligned and spliced, they can vertically pass through the Larssen sheet pile body 5. Pile holes 6 are opened at both ends of the A-type clamping plate 1 and the B-type clamping plate 2. Each fixing pile 4 passes through one pile hole 6 and is fixed to the ground. The fastener 3 is fixedly installed on the A-type clamping plate 1 and the B-type clamping plate 2 and is located on both sides of the recessed part of the Larssen sheet pile body 5.

[0026] In this embodiment, lifting rings 7 are provided on type A plate 1 and type B plate 2, and the lifting rings 7 are fixedly installed on the opposite sides of the serrated edges of type A plate 1 and type B plate 2. Two lifting rings 7 are welded to the front end of type A plate 1 and the rear end of type B plate 2 for use in lifting and installation on the construction site.

[0027] In this embodiment, the fastener 3 includes a rectangular steel component 8, a fastening plate 9, a threaded cylinder 10, and a rotating handle 11. The rectangular steel component 8 is fixedly installed on type A clamping plate 1 and type B clamping plate 2. The rotating handle 11 is fixedly installed at one end of the threaded cylinder 10, and the fastening plate 9 is rotatably installed at the other end of the threaded cylinder 10. The threaded cylinder 10 passes through the rectangular steel component 8 by being screwed in. Rotating the rotating handle 11 controls the distance between the threaded cylinder 10 located on the rectangular steel component 8 and the Larssen sheet pile body 5. The lateral perpendicularity of the Larssen sheet pile body 5 is fixed by the fastening plate 9 at the other end, thereby achieving control of the lateral perpendicularity of the Larssen sheet pile body 5.

[0028] In this embodiment, the steel plate thickness within a 280mm range on the left side of Type A clamping plate 1 and Type B clamping plate 2 decreases downwards to 25mm, and the steel plate thickness within a 280mm range on the right side of Type A clamping plate 1 and Type B clamping plate 2 decreases upwards to 25mm. Figure 5 and Figure 6 As shown. Because its left end thins downwards and its right end thins upwards, another type A plate 1 and type B plate 2 can be spliced ​​at the left or right end to continue driving the subsequent Larssen sheet pile body 5.

[0029] Furthermore, in the implementation scheme of this embodiment, a pile hole 6 with a diameter of 50mm is drilled at the left end of the A-type card plate 1 at 100mm from the front edge and 100mm from the left edge, at the right end at 100mm from the front edge and 180mm from the right edge. Similarly, a pile hole 6 with a diameter of 50mm is drilled at the left end of the B-type card plate 2 at 100mm from the rear edge and 100mm from the left edge, at the right end at 100mm from the rear edge and 180mm from the right edge. These holes are used to fix the pile 4 through which the pile 4 passes and is then fixed to the ground.

[0030] During construction, firstly, the fixing pile 4 passes through the pile holes 6 at both ends of the single A-type clamp 1 and B-type clamp 2, fixing the single A-type clamp 1 and B-type clamp 2 into the soil on both sides of the longitudinal direction of the Larssen steel sheet pile body 5 supporting the retaining wall. Figure 2 As shown. Two lifting rings 7 are welded to the front end of type A plate 1 and the rear end of type B plate 2 for on-site lifting and installation. The lifting rings 7 are made of HPB300 plain round steel bars with a diameter of 20mm. The fixing pile 4 is made of a circular steel column with a diameter of 40mm and a length of 500mm. A cylindrical steel plate with a diameter of 80mm and a thickness of 15mm is welded to the upper end of the fixing pile 4 for pressing down and pulling up the fixing pile 4. During construction, the Larssen steel sheet pile body 5 passes through the hole formed by the splicing of type A plate 1 and type B plate 2 and is pressed down to achieve longitudinal vertical control of the Larssen steel sheet pile body 5. The Larssen steel sheet pile body 5 at both ends of each plate is constructed first, and then the Larssen steel sheet pile body 5 in the middle of each plate is constructed in sequence. As each Larssen sheet pile body 5 is pressed down, the fasteners 3 on both longitudinal sides of the Larssen sheet pile body 5 can be adjusted at any time. Rotating the handle 11 controls the distance between the threaded cylinder 10 on the rectangular steel member 8 and the Larssen sheet pile body 5. The lateral perpendicularity of the Larssen sheet pile body 5 is then fixed by the fastening plate 9 at the other end, thus controlling the lateral perpendicularity of the Larssen sheet pile body 5. After the combined single A-type clamping plate 1 and B-type clamping plate 2 are inserted into the Larssen sheet pile body 5, because its left end thins downwards and its right end thins upwards, another A-type clamping plate 1 and B-type clamping plate 2 can be spliced ​​at the left or right end to continue driving subsequent Larssen sheet pile bodies 5. After the previously constructed Larssen sheet pile body 5 is completed, the A-type clamping plate 1 and B-type clamping plate 2 can be removed for subsequent construction.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
