[0023] The steel sheet pile retaining structure of this utility model embodiment is described in detail below with reference to the accompanying drawings.

[0024] Reference Figure 1 As shown, the sheet pile retaining structure provided in this embodiment of the present invention includes: a plurality of sheet pile bodies 10 and a waler 20. The plurality of sheet pile bodies 10 are used to interlock and enclose each other in the horizontal direction. Each sheet pile body 10 includes at least an interlocking plate 11 and an installation plate 12 extending from the top of the interlocking plate 11 and bent to be parallel to the length direction of the interlocking plate 11. The interlocking plate 11 and the installation plate 12 support each other in the horizontal direction. The waler 20 is detachably connected to the installation plate 12 so that the plurality of sheet pile bodies 10 are horizontally supported by the waler 20.

[0025] The sheet pile body 10 can be manufactured using existing cold rolling and bending processes. By cold rolling and bending the interlocking plate 11 and the mounting plate 12, the sheet pile body 10 does not need to be additionally welded or have its manufacturing process changed. Furthermore, the integrated cold rolling and bending process simplifies the overall structure formation. The sheet pile body 10 can be made of steel such as Q235 or Q345 to ensure its strength and durability.

[0026] In a specific embodiment, when constructing and installing the above-mentioned retaining structure, a vibratory hammer or similar device can be used to drive the sheet pile body 10 into the foundation pit. When driving adjacent sheet pile bodies 10 into the foundation pit, the interlocking plate 11 can be positioned and aligned before driving the adjacent sheet pile bodies 10 in sequence. After enclosing multiple sheet pile bodies 10, the waler 20 can be installed. Since the waler 20 and the installation plate 12 are detachably connected, the installation method is simpler and more efficient.

[0027] As an optional embodiment, such as Figure 2 As shown, the steel sheet pile retaining structure can be provided with steel sheet piles without the plate body 12 installed on the outside, while the steel sheet pile body 10 is used on the inside. This not only improves the lateral bearing capacity of the retaining structure, but also reduces the overall installation cost.

[0028] Reference Figure 3 and Figure 4 As shown, the interlocking plate 11 includes a support plate 111 and wings 112 that bend and extend from both ends of the support plate 111 in the width direction. The ends of the wings 112 are provided with interlocking parts 113, which are used to interlock adjacent sheet pile bodies 10.

[0029] In this embodiment, the interlocking part 113 can be positioned and inserted in the vertical direction, so that the interlocking part 113 can form an interlock in the horizontal direction. This allows several sheet pile bodies 10 to be tightly connected together through the interlocking part 113 to form a continuous wall, thereby enabling the retaining structure to effectively resist the lateral pressure of soil or water.

[0030] Furthermore, the interlocking part 113 includes an arc-shaped segment 1131 and a straight segment 1132. One end of the arc-shaped segment 1131 is connected to the wing 112, and the other end is connected to the straight segment 1132. Adjacent interlocking parts 113 can be inserted along the length direction, so that adjacent straight segments 1132 fit together, and the straight segment 1132 and the arc-shaped segment 1131 can be engaged and interlocked in at least two directions on the horizontal plane, ensuring that adjacent sheet pile bodies 10 can be tightly connected. Optionally, the straight segment 1132 and the wing 112 are parallel to each other along the length direction.

[0031] Optionally, the angle between the arc segment 1131 and the straight segment 1132 is 30 degrees to 90 degrees; wherein, the angle between the arc segment 1131 and the straight segment 1132 is α, 30° < α < 90°, for example, α can be 45°; and, the radian of the arc segment 1131 is 3.66 rad to 5.8 rad, for example, the radian of the arc segment 1131 can be set to 5.2 rad. When setting the angle between the arc segment 1131 and the straight segment 1132 and the radian of the arc segment 1131, it is necessary to ensure that the adjacent interlocking parts 113 can form an interlock to improve the stability between adjacent sheet pile bodies 10. Therefore, the above angle and radian are only examples and are not limited here.

[0032] Reference Figure 3 and Figure 5 As shown, the mounting plate 12 includes a connecting section 121 and a supporting section 122. One end of the connecting section 121 is connected to the supporting plate 111 and is perpendicular to the supporting plate 111. The supporting section 122 is connected to the other end of the connecting section 121 and is arranged parallel to the length direction of the supporting plate 111.

[0033] In this embodiment, by making the support plate 111 and the support segment 122 parallel, a double-layer structure can be formed between the support plate 111 and the support segment 122, thereby improving the overall lateral bearing capacity. The support plate 111 and the support segment 122 are connected integrally by the connecting segment 121, making the overall forming method simpler.

[0034] In a preferred embodiment, a plurality of connecting plates are provided between the support segment 122 and the support plate 111, and the plurality of connecting plates are spaced apart from each other, with each connecting plate being perpendicular to the support segment 122 and the support plate 111.

[0035] In a specific embodiment of this application, the connecting plate can be a polygonal structure, such as a triangle or quadrilateral. The connecting plate can be formed by welding. By welding and fixing the support section 122 and the support plate body through the connecting plate, the steel sheet pile body 10 can form a double-layer structure in the horizontal direction, resulting in higher overall bearing strength and better stability as a retaining structure for water conservancy projects. It can be understood that the connecting plate is perpendicular between the support section 122 and the support plate body 111, which can reduce the resistance when the steel sheet pile body 10 is driven into the foundation pit.

[0036] Specifically, both the connecting section 121 and the supporting section 122 are provided with first fixing holes 123, and the first fixing holes 123 on the supporting section 122 are spaced apart in the vertical direction; furthermore, the waler 20 is provided with second fixing holes 201, which are used to fix with the first fixing holes 123.

[0037] In this embodiment, bolts or similar fasteners can be inserted into the first fixing hole 123 and the second fixing hole 201 for fixation. During the installation of the waler 20, a crane or similar means can be used to hoist the waler 20 to the position of the first fixing hole 123, so that the first fixing hole 123 can be aligned with the second fixing hole 201 and then locked in place with bolts, ensuring a higher connection strength between the waler 20 and the mounting plate 12. Optionally, the waler 20 can be formed by splicing two channel steels. By setting the slots of the two channel steels opposite each other, bolts can be inserted for installation and fixation after splicing. It is understood that when splicing the waler 20 with two channel steels, the second fixing holes 201 on the two channel steels need to be coaxial to ensure better overall consistency.

[0038] The sheet pile retaining structure provided by this utility model can interlock several interlocking plates 11, so that several sheet pile bodies 10 can be enclosed to form a retaining structure. Then, the waler 20 and the mounting plate 12 are fixed with bolts or the like, so that the waler 20 can support the sheet pile body 10 on the inside of the retaining structure. Therefore, there is no need to weld the waler 20, avoiding the stability problems caused by welding, reducing construction costs and manpower requirements, and making the assembly and enclosure efficiency of the retaining structure higher.
