Description

Technical Field

[0001] The utility model relates to the technical field of support and water interception engineering, in particular to a multi-angle steel sheet pile angle pile. Background Art

[0002] Steel sheet piles are divided into U-shaped, Z-shaped, straight and cap-shaped steel sheet piles, which are widely used in engineering support and water diversion such as trenches, foundation pits and cofferdams. They are easy to construct, quick and reusable. Among them, U-shaped steel sheet piles are more commonly used. During construction, a steel sheet pile is first driven vertically into the soil, and then the locking mouth of another steel sheet pile is aligned with the locking mouth of the driven steel sheet pile and driven in. Then the locking mouth of the third steel sheet pile is aligned with the locking mouth of the previous steel sheet pile and driven in. And so on, they are driven in one by one to form a continuous steel sheet pile wall. This continuous steel sheet pile wall can be extended indefinitely.

[0003] Steel sheet piles can be connected in two ways: small lock-end and large lock-end. Small lock-end connections are often used in engineering projects. Small lock-end connections can fully utilize the cross-sectional rigidity and water-stopping effect of steel sheet piles, especially when water-stopping is required. However, the theoretical rotation angle of this small lock-end connection is generally 5°-6°. When the support requires a larger rotation angle, the small lock-end cannot be inserted, and the corner becomes a weak link in support and water-stopping. Currently, there are two ways to treat the corners of steel sheet pile walls: one is to leave them unconnected, and the other is to use T-shaped corner piles. Leaving corners unconnected weakens the structural integrity and water-stopping properties of the corner, especially the water-stopping properties, often creating groundwater seepage points. Using T-shaped corner piles can only be used for fixed angles, that is, one pile per angle, usually 90°, which cannot meet the universal applicability of steel sheet piles for reuse. Therefore, there is an urgent need for those skilled in the art to provide a multi-angle steel sheet pile corner pile with a large rotation angle, variable angle, and good connection effect. Utility Model Content

[0004] The purpose of the utility model is to provide a multi-angle steel sheet pile corner pile to solve the problems of poor connection effect of the corner position of the steel sheet pile corner pile, small and unchangeable rotation angle and poor universal applicability proposed in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multi-angle steel sheet pile corner pile, comprising a steel pipe (1) and a group lock buckle, wherein the group lock buckle comprises a plurality of first lock buckles (2), wherein the first lock buckles (2) are fixedly arranged on the steel pipe (1), and the first lock buckles (2) on the steel pipe (1) are connected to the steel sheet pile (3), wherein there are more than two steel sheet piles (3), and second lock buckles (4) are fixedly arranged at both ends of the steel sheet pile (3), and the steel sheet pile (3) is connected to the first lock buckle (2) through the second lock buckle (4) so ​​as to be connected to the steel pipe (1), and the angle between two steel sheet piles (3) adjacent to the steel pipe (1) is 90°-165°.

[0006] Furthermore, the cross section of the steel pipe (1) is circular or polygonal.

[0007] Furthermore, the second lock buckle (4) and the first lock buckle (2) fit together.

[0008] Furthermore, the group of lock buckles includes more than two groups, and the angle α between adjacent first lock buckles (2) in each group of lock buckles is 12°-30°. The angle α refers to the angle between adjacent lock openings in each group of lock buckles corresponding to the center of a circle, and also indicates the spacing between adjacent lock openings.

[0009] Furthermore, the angle θ between adjacent first lock buckles (2) between adjacent groups of lock buckles is less than or equal to 90°. The angle θ refers to the smaller central angle between adjacent first lock buckles between adjacent groups of lock buckles. The angle θ being less than 90° is conducive to meeting the requirement when the angle at the corner of the steel sheet pile wall support is less than 90°.

[0010] Furthermore, the angle between adjacent steel sheet piles (3) is preferably 90°, 105°, 120°, 135°, 150°, or 165°.

[0011] Furthermore, the length of the first locking buckle (2) is the same as the length of the steel pipe (1).

[0012] Furthermore, the length of the second lock buckle (4) is the same as the length of the steel sheet pile (3).

[0013] Furthermore, the first locking buckle (2) is rigidly arranged on the steel pipe (1), and any point on the first locking buckle (2) can be rigidly connected to the steel pipe (1). This can meet the overall connection performance and sealing and water-stopping performance of the corner support structure, and can realize the functions of variable angle connection and reuse of the steel sheet pile wall support corner.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: a multi-angle steel sheet pile corner pile of the present invention connects a plurality of first lock buckles of different angles to the steel pipe, so that the steel sheet pile can be connected to the steel pipe at any angle, thereby realizing a variable angle connection of the steel sheet pile wall support corner. Since the connections between the lock buckles fit together, the connection effect of the steel sheet pile wall support corner is good, the connection angle selectivity is large, and the universal applicability is strong.

[0029] Example 2

[0030] Please see the attached Figure 4 In this embodiment, a multi-angle steel sheet pile corner pile is provided. The cross section of the steel pipe 1 is a dodecagon. The angle θ between adjacent first lock buckles 2 in adjacent groups of lock buckles is equal to 90°. The angle α between adjacent first lock buckles 2 in each group of lock buckles is 30°. The angle between two steel sheet piles 3 adjacent to the steel pipe 1 is 120°. The rest is the same as in Example 1.
