Description

Technical Field

[0001] This utility model relates to the field of infrastructure construction technology, specifically to a type of support sheet pile. Background Technology

[0002] Sheet piles are a common type of support structure used in civil engineering, typically for preventing soil slippage, maintaining foundation pit stability, and supporting underground structures. They are primarily made of materials such as steel sheet piles, concrete sheet piles, or wooden plank piles. Depending on the application, sheet piles can be made of a single material or composite materials. Sheet piles form a retaining structure by being driven into the soil, preventing soil slippage or collapse and ensuring the stability of the surrounding environment. In environments with high water levels or high humidity, sheet piles can act as a waterproofing agent, preventing groundwater seepage into the construction area and mitigating changes in the water level of the foundation pit. During foundation pit excavation, tunnel construction, or other underground structure construction, sheet piles provide safety protection for the construction area, preventing soil collapse from harming workers and equipment.

[0003] However, most existing sheet pile supports are installed using either driving or insertion methods. Driving methods utilize pile drivers and vibratory hammers, while insertion methods involve inserting sheet piles into pre-drilled holes. However, when a sheet pile is driven into the soil, it only provides a downward force, which is the most direct fixing force. This force is typically achieved through friction between the pile and the soil layer, the weight of the pile, and the compressive force of the soil. When a sheet pile is directly inserted into the ground, it relies primarily on vertical insertion force and lateral friction to maintain stability. This means that sheet piles are primarily resistant to vertical loads (such as soil pressure and water pressure), but relatively weak against lateral forces (such as soil lateral pressure or external vibrations). To address these issues, a new type of sheet pile support is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a support sheet pile to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a support sheet pile, comprising: a pile body and an anchoring mechanism; The anchoring mechanism includes a insert, a gear, and a rotating rod. The insert has a toothed groove that matches the gear. The rotating rod rotates, causing the gear to rotate within the pile body, so that the insert extends out from below the side of the pile body. The insert is anchored in the soil, applying a lateral force to the pile body.

[0006] As a preferred technical solution of this utility model, one end of the insert is set as a pointed tip.

[0007] As a preferred technical solution of this utility model, a sliding groove matching the insert is provided on the side of the pile body, and both the gear and the rotating rod are rotatably installed in the pile body, with the rotating rod fixedly connected to the upper end of the gear and the upper end of the rotating rod extending out from the upper end of the pile body.

[0008] As a preferred technical solution of this utility model, two inserts are provided, arranged vertically, and the two inserts slide out from both sides of the pile body respectively.

[0009] As a preferred technical solution of this utility model, the gear and the rotating rod are slidably installed in the pile body.

[0010] As a preferred technical solution of this utility model, a rotating cylinder is rotatably installed at the upper end of the pile body, and a driving rod is fixedly connected to the upper end of the rotating rod. The driving rod is slidably installed inside the rotating cylinder.

[0011] As a preferred technical solution of this utility model, a screw is rotatably mounted on the upper end of the drive rod, and the screw is threadedly connected to the upper end of the rotating drum.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the lower end of the pile is inserted into the ground. By rotating the rotating rod, the gear is driven to rotate in the pile, which in turn drives the insert to extend from the lower side of the pile. The insert is anchored in the soil and applies a lateral force to the pile. This solves the problem that existing sheet piles mainly have strong resistance to vertical loads but are weak against lateral forces. Attached Figure Description

[0015] 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.

[0016] Please see Figure 1-7 This embodiment provides a support sheet pile, including a pile body 1. The pile body 1 is preferably a concrete sheet pile, manufactured by pouring concrete into a mold and allowing it to solidify. Reinforcing bars can be embedded within the pile body 1 to increase its structural strength. Figure 1 and Figure 2 As shown, a protruding strip is provided on one side of the pile body 1, and a groove matching the protruding strip is provided on the other side. The protruding strip of the pile body 1 can be inserted into the groove of the adjacent pile body 1, and multiple pile bodies 1 can be spliced ​​together to form a retaining structure.

[0017] The pile body 1 can be installed using either a pile driving method or an insertion method. This means that the pile body 1 is inserted into the ground using a pile driver or vibratory hammer, or the sheet pile is inserted into a pre-drilled hole in the ground. However, in actual use, it has been found that when the pile body 1 is directly inserted into the ground, it mainly relies on vertical insertion force and lateral friction to maintain stability. This implies that the sheet pile has strong resistance to vertical loads (such as soil pressure and water pressure), but is relatively weak against lateral forces (such as soil lateral pressure or external vibration). Therefore, an anchoring mechanism 2 is installed inside the pile body 1.

[0018] like Figure 4 As shown, the anchoring mechanism 2 includes inserts 21, gears 22, and rotating rods 23. Two inserts 21 are provided, and the pile body 1 has two grooves arranged vertically, with the openings of the grooves located on opposite sides of the pile body 1. The two inserts 21 are centrally symmetrically arranged and slidably installed within the two grooves. The end of each insert 21 facing the groove opening is a pointed tip, which reduces the contact area with the soil, concentrating pressure and increasing local pressure, thus facilitating the overcoming of soil resistance and insertion into the soil. The rotating rod 23 and gears 22 form a control unit, with the rotating rod 23 fixedly connected to the upper end of the gear 22. The control unit is movably installed within the pile body 1, meaning it can rotate and slide vertically within the pile body 1.

[0019] The insert 21 has a toothed groove on the side facing the gear 22 that matches the gear 22. By sliding the control component downwards, the lower insert 21 and gear 22 mesh together, which rotates the rotating rod 23. The rotating rod 23 drives the gear 22 to rotate, thereby causing the meshing lower insert 21 to extend out of the groove. Sliding the control component upwards, the upper insert 21 and gear 22 mesh together, which controls the upper insert 21 to extend out of the groove. After the lower end of the pile 1 is inserted into the ground, the control component drives the two inserts 21 to extend out from both sides of the pile 1. The inserts 21 are inserted into the soil, which forms an additional horizontal constraint force (lateral force) to resist the tilting of the pile 1 and improve the overall stability. In areas with high groundwater levels, buoyancy will exert an upward force on the pile 1, which may cause the sheet pile to float or loosen. In this case, the inserts 21 that extend and anchor in the soil can form an additional pull-out force, effectively preventing the pile 1 from shifting due to buoyancy. This is suitable for environments with high groundwater levels or hydraulic engineering projects. In theory, the longer the insert 21 extends and the deeper it is inserted into the soil, the greater the ability of the pile 1 to resist lateral forces.

[0020] However, gear 22 and rotating rod 23 are preferably made of metal, which has high strength, but correspondingly, the control components are also heavy. Therefore, manually operating the control components (sliding up and down and rotating) is relatively difficult. To facilitate the operation of the control components, a rotating cylinder 3 is rotatably installed at the upper end of the pile body 1. Figure 7 As shown, a drive rod 231 is fixedly connected to the upper end of the rotating rod 23, and a screw 232 is rotatably connected to the upper end of the drive rod 231. The drive rod 231 is configured as a regular polyhedral prism (a prism with a regular polygonal base, such as a regular triangular prism, a regular square prism, a regular pentagonal prism, or a regular hexagonal prism). The rotating cylinder 3 has a sliding cavity that matches the drive rod 231. The drive rod 231 is slidably installed in the sliding cavity. The upper end of the rotating cylinder 3 is configured as a regular hexagonal prism, which can be rotated by a wrench, thereby driving the rotating rod 23 to rotate via the drive rod 231. The screw 232 is threadedly connected to the upper end of the rotating cylinder 3. The screw 232 can be rotated by a wrench, thereby driving the drive rod 231 to slide up and down inside the rotating cylinder 3. That is, the rotating rod 23 drives the gear 22 to slide up and down inside the pile body 1 and mesh with the two inserts 21.

[0021] Compared to manually moving or rotating the control components, using a wrench to drive the rotating drum 3 and screw 232 is more labor-saving and easier to operate.

[0022] 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.
