Description

Technical Field

[0001] The present application relates to the technical field of sheet piles, and in particular to a composite plastic-steel sheet pile. Background Art

[0002] Plastic steel sheet piles are a type of sheet pile revetment, usually used on river banks and coasts. Specifically, the plastic steel sheet piles are driven (vibrated) into the foundation of the shore to resist horizontal pressure (such as the water pressure generated by sea water or river water rushing to the shore) and prevent river water or sea water from scouring the shore.

[0003] Figure 1 FIG. 1 shows a schematic top view of a plastic-steel sheet pile provided in the prior art, such as Figure 1 As shown, the main body of the plastic steel sheet pile is usually a non-metallic hard material plate (such as a hard plastic plate with a certain thickness). In order to increase the strength of the plastic steel sheet pile, a plum blossom pile made of non-metallic hard material is usually added at the corner of the non-metallic hard material plate, and a steel bar is driven into the plum blossom pile. Among them, when the plastic steel sheet pile is used, the extension direction of the plum blossom pile is perpendicular to the foundation.

[0004] Each plum blossom pile has a cap on the top. No matter how tightly the cap is closed, there will still be a gap between the cap and the plum blossom pile. After a period of use, water and air will enter the plum blossom pile. The water and air entering the plum blossom pile will corrode the steel bars in the plum blossom pile, resulting in a decrease in the strength of the plastic steel sheet pile. Utility Model Content

[0030] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0031] Considering that no matter how tightly the cap on the plum blossom pile is covered, there will still be a gap between the cap and the plum blossom pile. After a period of use, water and air will enter the plum blossom pile, and the water and air entering the plum blossom pile will corrode the steel bars in the plum blossom pile, resulting in a decrease in the strength of the plastic steel sheet pile. Based on this, the embodiment of the present application provides a composite plastic steel sheet pile to enhance the strength of the plastic steel sheet pile, which is described below through an embodiment.

[0032] To facilitate understanding of this embodiment, a composite plastic-steel sheet pile disclosed in an embodiment of the present application is first introduced in detail. Figure 2 FIG. 1 shows a three-dimensional schematic diagram of a composite plastic-steel sheet pile provided in an embodiment of the present application, such as Figure 2 As shown, the composite plastic-steel sheet pile includes a metal plate 1 and a closed plastic-steel plate 2; wherein, the closed plastic-steel plate 2 contains at least one first hollow portion, and each first hollow portion is filled with a metal plate 1, so that the metal plate 1 is completely sealed and wrapped in the closed plastic-steel plate 2; the difference between the height of the closed plastic-steel plate 2 and the height of the metal plate 1 is greater than 0 and less than half of the height of the metal plate 1.

[0033] In this embodiment, the number of the first hollow parts is the same as the number of the metal plates 1. The distance between the top of the first hollow part and the top of the closed plastic steel plate 2 is equal to the distance between the bottom of the first hollow part and the bottom of the closed plastic steel plate 2. That is, in the direction perpendicular to the ground, the first hollow part is located in the middle of the closed plastic steel plate 2.

[0034] In this embodiment, the difference between the height of the closed plastic steel plate 2 and the height of the metal plate 1 refers to: the sum of the distance between the top of the metal plate 1 and the top of the closed plastic steel plate 2 and the distance between the bottom of the metal plate 1 and the bottom of the closed plastic steel plate 2. The difference between the height of the closed plastic steel plate 2 and the height of the metal plate 1 can be greater than one tenth of the height of the metal plate 1 and less than one quarter of the height of the metal plate 1.

[0035] In this embodiment, the closed plastic-steel plate 2 including at least one first hollow portion is an integrally formed plastic-steel plate, and the metal plate 1 is sealed and filled into the first hollow portion inside the closed plastic-steel plate 2, so that the metal plate 1 inside the closed plastic-steel plate 2 can be prevented from contacting water and air, thereby preventing the metal plate 1 from being corroded, and further ensuring the strength of the composite plastic-steel sheet pile.

[0036] In a possible implementation, the metal plate 1 is a rigid metal plate, specifically a steel plate.

[0037] In one possible implementation, Figure 3 The top view of the two ends of a composite plastic-steel sheet pile provided in an embodiment of the present application is shown. Figure 3 As shown, the two ends of the composite plastic steel sheet pile are respectively a plug connector 3 and a plug slot 4 locked with the plug connector. Among them, the plug connector 3 is a T-shaped plug connector, and the plug slot 4 is a T-shaped plug slot.

[0038] In this embodiment, when two composite plastic-steel sheet piles are connected, the plug connector 3 of one composite plastic-steel sheet pile can be plugged into the plug slot 4 of the other composite plastic-steel sheet pile.

[0039] In a possible implementation, the composite plastic-steel sheet pile is inserted vertically into the ground during use. In a direction perpendicular to the ground, the area of ​​the orthographic projection of the metal plate 1 is smaller than the area of ​​the orthographic projection of the closed plastic-steel plate 2.

[0040] In a possible implementation, Figure 2 As shown, when the number of the first hollow portion is one, the shape of the metal plate 1 is parallel to the shape of the closed plastic-steel plate 2 in the extension direction parallel to the ground.

[0041] In this embodiment, the closed plastic-steel plate 2 has two extension directions, one is a height direction perpendicular to the ground, and the other is a length direction parallel to the ground. The extension direction of the closed plastic-steel plate 2 parallel to the ground refers to the length direction parallel to the ground.

[0042] In another possible embodiment, the metal plate 1 is in the shape of a long strip; for each metal plate 1 in the composite plastic-steel sheet pile, the plane where the length and height of the metal plate 1 are located is parallel to the plane where the length and height of the closed plastic-steel plate 2 are located, or the plane where the length and height of the metal plate 1 are located is parallel to the plane where the width and height of the closed plastic-steel plate 2 are located.

[0043] In this embodiment, Figure 4 A three-dimensional schematic diagram showing the positions of multiple metal plates in a composite plastic-steel sheet pile provided in an embodiment of the present application is shown. Figure 4 As shown, when the same composite plastic-steel sheet pile contains multiple metal plates 1 arranged in parallel, for each metal plate 1 in the same composite plastic-steel sheet pile, the plane where the height of the metal plate 1 is located is parallel to the plane where the height of the closed plastic-steel plate 2 is located.

[0044] Figure 5 A three-dimensional schematic diagram showing the positions of another plurality of metal plates in a composite plastic-steel sheet pile provided in an embodiment of the present application is shown. Figure 5 As shown, the plane where the length and height of each metal plate 1 in the same composite plastic-steel sheet pile is located is parallel to the plane where the width and height of the closed plastic-steel plate 2 are located. Among them, the area of ​​the plane where the length and height of the closed plastic-steel plate 2 are located is larger than the area of ​​the plane where the width and height are located.

[0045] In this embodiment, compared with Figure 2 As shown in the figure, a whole metal plate 1 is arranged inside the closed plastic steel plate 2, by Figure 4 and Figure 5 The method of arranging a metal plate 1 at a preset distance inside the closed plastic steel plate 2 is helpful to reduce the material used for the metal plate.

[0046] In one possible implementation, Figure 6 FIG. 2 shows a top view of the second hollow portion inside the closed plastic steel plate provided in an embodiment of the present application. Figure 6 As shown, a second hollow portion 5 is disposed between any two adjacent first hollow portions; the height of the first hollow portions, the height of the second hollow portion 5, and the height of the metal plate 1 are the same.

[0047] In this embodiment, the distance between the top of the second hollow part and the top of the closed plastic steel plate 2 is equal to the distance between the bottom of the second hollow part and the bottom of the closed plastic steel plate 2. That is, in the direction perpendicular to the ground, the second hollow part is located in the middle of the closed plastic steel plate 2.

[0048] In this embodiment, the above method is helpful to reduce the material used for the metal plate and the material used for the closed plastic steel plate.

[0049] In a possible implementation, in the extension direction of the composite plastic-steel sheet pile parallel to the ground, the shape of the composite plastic-steel sheet pile includes one or more continuous target shapes; the target shape is a trapezoid, a triangle or a wave.

Figure 7 The top view of the composite plastic-steel sheet pile provided in the embodiment of the present application is shown, and the shape trend includes two continuous trapezoids, such as Figure 7 As shown, the shape of the composite plastic-steel sheet pile includes two continuous trapezoids.

[0051] In this embodiment, compared with Figure 2 The shape of the composite plastic-steel sheet pile shown is a long strip (i.e., the remaining part of the composite plastic-steel sheet pile except the two ends is a flat plastic-steel plate). In this embodiment, the shape of the composite plastic-steel sheet pile includes one or more continuous target shapes, and the target shapes are trapezoidal, triangular or wavy, which is beneficial to enhance the strength of the composite plastic-steel sheet pile to resist horizontal pressure and prevent the composite plastic-steel sheet pile from being knocked down by horizontal pressure (such as water pressure generated by sea water or river water washing to the shore, or wind pressure generated by wind) during use.

[0052] In one possible implementation, Figure 8 FIG. 1 shows a top view of a composite plastic-steel sheet pile provided in an embodiment of the present application, in which a hollow plum blossom pile is arranged at each corner. Figure 8 As shown, in order to further enhance the strength of the composite plastic-steel sheet pile, a hollow plum blossom pile 6 is arranged at each corner of the same composite plastic-steel sheet pile, and the hollow space inside the hollow plum blossom pile 6 is used to fill a steel bar; the hollow plum blossom pile 6 is a closed hollow plum blossom pile or a hollow plum blossom pile with a cap top.

[0053] In this embodiment, the closed hollow plum blossom pile and the steel bar therein are integrally formed, and the closed hollow plum blossom pile is conducive to preventing water and air from entering the hollow plum blossom pile 6, thereby preventing the steel bar therein from being corroded. The hollow plum blossom pile with a cap is conducive to improving the portability of steel bar installation.

[0054] In a possible implementation, Figure 8 As shown, the plug connector 3 is a T-shaped plug connector, and the plug slot 4 is a T-shaped plug slot; one end of the three composite plastic-steel sheet piles are connected by the same plastic-steel connecting component, so that the three composite plastic-steel sheet piles are T-connected; the height of the plastic-steel connecting component is the same as the height of the composite plastic-steel sheet pile; Fig. 9 FIG. 1 shows a top view of a plastic-steel connecting component provided in an embodiment of the present application, such as Fig. 9 As shown, the plastic-steel connecting component includes two T-shaped plug connectors and a T-shaped plug slot locked with the T-shaped plug connectors; the two T-shaped plug connectors in the plastic-steel connecting component are perpendicular to each other; the groove opening direction of the T-shaped plug slot in the plastic-steel connecting component is opposite to the direction of one of the T-shaped plug connectors and perpendicular to the direction of the other T-shaped plug connector.
