[0002] Sheet piles, as a traditional retaining and decoupling material, have advantages such as quick construction, safety, environmental protection, and aesthetics, and are widely used in industries such as transportation, water conservancy, and municipal engineering.

[0003] Sheet piles are typically designed in a modular fashion and detachable connection to form an integrated protective structure. The connection between adjacent sheet piles usually uses corresponding interlocking connection technology, and the adjacent sheet piles are connected as one unit through a precast groove structure.

[0004] Furthermore, during the installation of sheet piles, high-frequency vibratory hammers are typically used to drive the sheet piles. Since sheet piles are usually prefabricated structures, their overall structural strength is easily affected by the environment during transportation and storage, which in turn affects the driving effect of the high-frequency vibratory hammers and the use of the sheet piles.

[0005] Chinese patent CN221741241U discloses a composite sheet pile, comprising several connecting units. Each connecting unit includes a first sheet pile and a second sheet pile, which are arranged adjacent to each other. Both sides of the first sheet pile have an interlocking connection part, which is hook-shaped. The back of the first sheet pile has a long groove along its length, and a T-shaped steel is engaged in the long groove. The upper part of the back of the second sheet pile has a slot, and a T-shaped plate is engaged in the slot. The T-shaped plate is used to spread the sheet piles at both ends apart.

[0006] The aforementioned sheet pile connects the first and second sheet piles through a fitting joint. This requires high precision in the processing of the sheet piles and the fitting joint. Furthermore, it is difficult to adjust the angle of the protective surface, making it unsuitable for complex protective environments. Additionally, when the sheet pile is driven by a vibratory hammer, the top of the sheet pile is prone to deformation under the vibration of the hammer, affecting the driving effect.

Detailed Implementation

[0040] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0041] like Figures 1-15 As shown, a composite sheet pile structure includes several sheet pile bodies 1 connected in sequence. Each sheet pile body 1 has a first hook section 2 and a second hook section 3 that can be tightened together at both ends along the arrangement direction. Adjacent sheet pile bodies 1 are arranged in opposite directions. The bottom of each sheet pile body 1 has an inclined pile tip 11 that facilitates the driving of the sheet pile body 1. The top of each sheet pile body 1 is cast in place with a capping beam 6 for cooperating with the driving of the sheet pile body 1.

[0042] The number of sheet pile bodies 1 is set according to actual needs. Under the action of the first hook section 2 and the second hook section 3, multiple sheet pile bodies 1 are connected in sequence. The inclined pile tip 11 increases the soil breaking pressure of the sheet pile body 1 under the effect of reducing the area, thereby facilitating the driving of the sheet pile body 1. The top beam 6 is used to strengthen the top strength of the sheet pile body 1, prevent the vibratory hammer from damaging the sheet pile body 1, and ensure the integrity and reliability of the sheet pile body 1.

[0043] The orientation of the inclined pile tips 11 of adjacent sheet pile bodies 1 is set according to actual needs. The inclined pile tips 11 arranged in a row can be in the same or opposite directions.

[0044] The top of the sheet pile body 1 is pre-embedded with a pre-embedded sleeve 51, and the capping beam 6 is provided with an anchor bar 61 connected to the pre-embedded sleeve 51. The anchor bar 61 is used to strengthen the structural strength of the capping beam 6, thereby meeting the pile driving requirements of the vibratory hammer.

[0045] The pre-embedded sleeve 51 is flush with the top of the sheet pile body 1, and the anchor bar 61 can be directly connected to the pre-embedded sleeve 51 at the top of the sheet pile body 1. The sheet pile body 1 is provided with a steel cage 5 for prefabricating the sheet pile body 1. The pre-embedded sleeve 51 is connected to the top of the steel cage 5, so that the anchor bar 61 and the steel cage 5 are connected through the pre-embedded sleeve 51, which further strengthens the strength of the anchor bar 61.

[0046] like Figures 1-5 As shown in Embodiment 1, the first barb segment 2 and the second barb segment 3 are symmetrically arranged along the middle of the sheet pile body 1, and both the first barb segment 2 and the second barb segment 3 extend outward along the arrangement direction of the sheet pile body 1.

[0047] The dimensions of the first hook segment 2 and the second hook segment 3 gradually increase from the inside to the outside along the arrangement direction of the sheet pile body 1, and a mutually tightening inclined surface is formed at the connection between the first hook segment 2 and the second hook segment 3.

[0048] Both the first barb segment 2 and the second barb segment 3 are trapezoidal structures. The connection between the first barb segment 2 and the adjacent second barb segment 3 forms an inclined surface whose size gradually increases from the inside to the outside. Similarly, the connection between the second barb segment 3 and the adjacent first barb segment 2 also forms an inclined surface whose size gradually increases from the inside to the outside.

[0049] The first hook section 2 and the second hook section 3 are interlocked and tightened to limit the sheet pile body 1 along the arrangement direction, thereby achieving a tight arrangement of several sheet pile bodies 1 in sequence.
