Curved sheet piles and retaining walls

Abstract

This utility model discloses an arc-shaped sheet pile and retaining wall, belonging to the field of support technology. The arc-shaped sheet pile includes a sheet pile body with an arc-shaped cross-section and a central angle of 60°~120°; connectors symmetrically installed on both sides of the sheet pile body; and a steel reinforcement cage placed inside the sheet pile body. The arc-shaped sheet pile provided by this utility model, by setting the cross-section of the sheet pile body to a minor arc shape and controlling its central angle to 60°~120°, ensures that the connection between the connector and the side end face forms a certain angle with respect to the axis of symmetry of the cross-section. This angle allows the retaining wall composed of arc-shaped sheet piles to have the connectors of adjacent arc-shaped sheet piles abut against each other when subjected to forces in any direction, increasing the interlocking area to resist external forces and thus improving the load-bearing capacity of the retaining wall.

Description

Technical Field

[0001] This utility model relates to the field of support technology, and in particular to curved sheet piles and retaining walls. Background Technology

[0002] In the fields of civil engineering and hydraulic engineering, sheet piles are widely used as a foundation support component in scenarios such as revetments and retaining walls. Traditional sheet piles mostly adopt a semi-circular cross-section design, and their production process is usually based on casting in a circular mold in one go. Then, along the diameter of the circular mold, they can be divided into two sheets with a semi-circular cross-section.

[0003] While this design simplifies the mold manufacturing process, in practical applications, the interlocking degree between adjacent sheet piles is insufficient. Because the central angle of a semi-circular sheet pile is 180°, its end tangent direction is parallel to the contact surface of adjacent sheet piles, resulting in linear contact (rather than surface contact) only at the end faces during splicing, thus limiting the interlocking area. Under lateral earth pressure or water flow impact, this structure can lead to at least one sheet pile having a lower overall load-bearing capacity due to limited stress at the connection point, potentially causing movement or collapse.

[0004] Although existing technologies attempt to improve interlocking strength by optimizing materials or adding connectors, such improvements require additional processing steps, increasing manufacturing costs and construction complexity. Utility Model Content

[0005] This utility model aims to solve the problems of limited interlocking area and small load of semi-circular sheet piles in the prior art, and provides arc-shaped sheet piles, forming molds and retaining walls.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] Firstly, this utility model provides an arc-shaped sheet pile, including a sheet pile body with an arc-shaped cross-section and an arc center angle of 60°~120°; connectors symmetrically installed on both sides of the sheet pile body; and a steel reinforcement cage placed inside the sheet pile body.

[0008] In one embodiment, the two ends of the sheet pile body along its length are side faces, and the connector is installed on the side faces, so the included angle between the two side faces is 60°~120°.

[0009] In one embodiment, the sheet pile body further includes an inner end face and an outer end face, at least one of the inner end face and the outer end face being a rough surface. The rough surface of the concrete facilitates the accumulation of moisture and dust, providing more attachment points for mosses and ferns, thus promoting plant growth. Typically, the inner end face is rough, but it is also possible for both the inner and outer end faces to be rough.

[0010] In one embodiment, the connectors are installed in a mirror-symmetrical manner on both sides of the sheet pile body.

[0011] In one embodiment, the connectors are centrally symmetrically installed on both sides of the sheet pile body.

[0012] Secondly, this utility model also provides a forming mold for producing any of the above-mentioned arc-shaped sheet piles, including a mold body and a dividing device. The cross-section of the mold body is circular, and the dividing device is installed longitudinally inside the mold body to divide the mold body into multiple fan-shaped rings.

[0013] The curved sheet piles with different shapes of connectors can be produced by changing the cross-sectional shape of the separating device. Furthermore, the size of the arc center angle of the curved sheet pile and the number of curved sheet piles produced at one time can be adjusted by controlling the number and installation position of the separating devices.

[0014] In one embodiment, the separating device consists of multiple independent partitions, the cross-sectional shape of which corresponds to the cross-sectional shape of the connecting member of the arc-shaped sheet pile.

[0015] In one embodiment, the separating device includes a central column, a partition plate, and connecting beams. The partition plate is located at the end of the fan-shaped ring, and the central column is located at the center of the annular ring of the mold body. The partition plate is longitudinally parallel to the central column through a plurality of connecting beams.

[0016] In one embodiment, the shape of the cross-section of the partition corresponds to the shape of the cross-section of the connector of the arc-shaped sheet pile.

[0017] Finally, this utility model provides a retaining wall formed by interconnecting at least two of the aforementioned arc-shaped sheet piles.

[0018] Beneficial effects: The arc-shaped sheet piles provided by this utility model, by setting the cross-section of the sheet pile body to a minor arc shape and controlling its arc center angle to be 60°~120°, ensure that when the arc-shaped sheet piles are connected to form a retaining wall, the connection point between its connector and the side end face forms a certain angle with respect to the axis of symmetry of the cross-section. This angle allows the connectors of adjacent arc-shaped sheet piles to abut against each other and increase the interlocking area to resist external forces when the retaining wall is subjected to forces in any direction, thereby improving the load-bearing capacity of the retaining wall. Furthermore, compared to the semi-circular sheet piles in the prior art, the minor arc-shaped sheet piles provided by this utility model can effectively utilize the perimeter of the sheet piles after being connected to form a retaining wall, significantly increasing its retaining width, thereby further improving the load-bearing capacity of the retaining wall.

[0033] To make the objectives and technical solutions of the present utility model clearer, 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, not all, of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0034] like Figure 1 As shown, Embodiment 1 of this utility model provides an arc-shaped sheet pile 1, including a sheet pile body 11, connectors 12, and a reinforcing steel cage 13. The cross-section of the sheet pile body 11 is an inferior arc shape. The connectors 12 are installed on both sides of the sheet pile body 11, and the connectors 12 and the sheet pile body 11 are integrally formed. The reinforcing steel cage 13 is placed inside the sheet pile body 11.

[0035] Please combine Figure 2 The sheet pile body 11 includes two side end faces 111, an inner end face 112, and an outer end face 113. The central arc angle α of the cross-section of the sheet pile body 11 is 60°~120°, that is, the included angle between the two side end faces 111 is 60°~120°. At least one of the inner end face 112 and the outer end face 113 is a rough surface. The rough surface of the concrete easily accumulates moisture and dust, providing more attachment points for mosses and ferns, which is more conducive to plant growth. Normally, the inner end face 112 is a rough surface. In this embodiment, both the inner end face 112 and the outer end face 113 are rough surfaces.

[0036] Two connectors 12 are mirror-symmetrically installed on both sides of the sheet pile body 11, with each connector 12 protruding from the side end face 111 of the sheet pile body 11. In this embodiment, the tangent 121 of the connector 12 can be parallel to the side end face 111, meaning the tangent of the connector 12 forms a certain angle with the axis of symmetry of the sheet pile body 11. Of course, in other embodiments, the tangent 121 and the side end face 111 can also be non-parallel, with the tangent 121 forming a certain angle with the axis of symmetry of the sheet pile body 11.

[0037] The reinforcing steel cage 13 includes main bars 131 and stirrups 132. Multiple main bars 131 are longitudinally arranged inside the sheet pile body 11, and their length is less than or equal to the length of the sheet pile body 11. The stirrups 132 are arranged inside the sheet pile body 11 along the cross-sectional direction of the sheet pile body 11. In this embodiment, the stirrups 132 are fan-shaped, and the main bars 131 are arranged along the stirrups 132, with two rows of main bars 131 respectively arranged on the same side of the fan-shaped stirrups 132.

[0038] Of course, in other embodiments, such as Figure 3 As shown, the stirrups 132 can also be arranged in a single layer around the main reinforcement 131.

[0039] like Figure 4As shown, Embodiment 1 of this utility model also provides a retaining wall 2, which is formed by interconnecting the arc-shaped sheet piles 1. Specifically, the connector 12 of one of the arc-shaped sheet piles 1 is tightly connected to the side end faces 111 of two adjacent arc-shaped sheet piles 1 to form the retaining wall 2. Since the cross-section of the sheet pile body 11 of the arc-shaped sheet pile 1 is a minor arc shape, the connection between the connector 12 and the side end face 111 forms a certain angle β with respect to the axis of symmetry. The existence of the angle β ensures that when the retaining wall 2 is subjected to force in any direction, the connectors 12 of two adjacent arc-shaped sheet piles 1 can abut against each other to resist the external force.

[0040] like Figure 5 As shown, in some other embodiments of the arc-shaped sheet pile 1, the two connecting members 12 can also be centrally symmetrically installed on both sides of the sheet pile body 11, with the connecting members 12 protruding from the side end face 111 of the sheet pile body 11. The retaining wall 2 formed by the interconnection of these arc-shaped sheet piles 1 is as follows: Figure 6 As shown.

[0041] like Figure 7 As shown, Embodiment 1 of this utility model also provides a forming mold 3 for manufacturing the arc-shaped sheet pile 1, including a mold body 31 and a dividing device 32. The cross-section of the mold body 31 is circular, and the dividing device 32 is installed longitudinally inside the mold body 31 along the length direction of the mold body to divide the mold body 31 into multiple fan-shaped parts.

[0042] The separating device 32 can be multiple partitions 322 with cross-sectional shapes corresponding to the cross-sectional shape of the connector 12. These partitions 322 are independent of each other, and by changing the cross-sectional shape of the partitions 322, arc-shaped sheet piles 1 with different shapes of connectors 12 can be produced. Furthermore, by controlling the number and installation position of the partitions 322, the arc center angle of the arc-shaped sheet pile 1 and the number of arc-shaped sheet piles 1 produced at one time can be adjusted. For example, in this embodiment, the forming mold 3 includes four partitions 322 symmetrically installed in pairs within the mold body 31. Using the forming mold 3, four arc-shaped sheet piles 1 can be produced simultaneously, and the arc angle of the arc-shaped sheet pile 1 is approximately 90°.

[0043] Please combine Figure 8 and Figure 9In other embodiments, the separating device 32 can also be a columnar frame structure, including a central column 321, partitions 322, and connecting beams 323. During assembly, the central column 321 is placed at the center of the mold body 31, and the partitions 322 are longitudinally parallel to the central column 321 through multiple connecting beams 323. The partitions 322 are placed inside the mold body 31. The cross-section of the central column 321 can be triangular, quadrilateral, or circular, etc. The cross-sectional shape of the partitions 322 corresponds to the cross-sectional shape of the connecting member 12, and can be a hollow column or a solid column. By controlling the number and installation position of the partitions 322 on the separating device 32, the size of the arc center angle of the arc sheet pile 1 and the number of arc sheet piles 1 produced at one time can be adjusted. For example, in this embodiment, the cross-section of the central column 321 is circular, and the number of partitions 322 is four.

[0044] In summary, the arc-shaped sheet pile provided by this utility model, by setting the cross-section of the sheet pile body to a minor arc shape and controlling its arc center angle to be 60°~120°, ensures that when the arc-shaped sheet piles are connected to form a retaining wall, the connection between the connector and the side end face forms a certain angle β relative to the axis of symmetry of the cross-section. The existence of the angle β allows the connectors of two adjacent arc-shaped sheet piles to abut against each other and increase the interlocking area to resist external forces when the retaining wall composed of arc-shaped sheet piles is subjected to forces in any direction, thereby improving the load-bearing capacity of the retaining wall.

Anyone skilled in the art can make some modifications and refinements without departing from the spirit and scope of the present invention.
