AI Technical Summary
Existing steel sheet pile structures cannot be installed at right angles or smaller angles during installation and are prone to bending. They have a simple structure and are not convenient for connection at different angles.
A detachable cofferdam module was designed, which adopts a connecting buckle structure consisting of plug-in buckle 1 and plug-in buckle 2. There is a 90-degree angle between the plug-in buckles. A triangular support frame is provided inside the steel sheet pile, with a clamping plate on the top, a sharp chamfer on the bottom, and a wide opening on the side to facilitate connection at different angles and improve strength.
Flexible angle installation between steel sheet piles is achieved, which enhances the stability and strength of the structure, avoids bending, and adapts to various application scenarios.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel sheet pile cofferdams, in particular to a detachable cofferdam module for flood control projects. Background Art
[0002] The steel sheet pile cofferdam is made by driving steel sheet piles one by one, and the steel sheet piles bite into each other and finally close into a whole, which can block the water and soil outside, thus forming a temporary water and soil retaining structure outside the foundation pit;
[0003] Most existing steel sheet pile structures are single steel plate structures, with buckle-shaped structures bent on both sides of the single steel plate structure to facilitate buckling between two steel sheet piles. However, due to the fixed position of the buckle-shaped structure and the single structure, it is only possible to buckle two steel sheet piles at a large angle, which is not convenient for installation and fixation at right angles or smaller angles between two steel sheet piles. In addition, when the single steel plate structure is used for pile insertion, if the direction of the pile insertion force and the insertion angle are too large, the steel sheet piles will easily bend. Utility Model Content
[0004] The technical problem to be solved by the utility model is that two existing adjacent steel sheet piles cannot be installed at a right angle or a smaller angle during installation, and the structure is relatively simple and easily bends.
[0005] In order to solve the above problems, the technical solution adopted by the present invention is a detachable cofferdam module for flood control projects, including a steel sheet pile structure, and two opposite sides of the steel sheet pile structure are fixed with connecting buckle structures, the connecting buckle structure includes plug-in buckle 1 and plug-in buckle 2, and a hollow area is opened inside the steel sheet pile structure, and several triangular support frame structures are fixed in the hollow area.
[0006] As a further solution of the present invention, there is a ninety-degree angle between the first plug-in buckle and the second plug-in buckle, which is convenient for adapting to different installation angles.
[0007] As a further solution of the present invention: a clamping plate is fixed on the top of the steel sheet pile structure to facilitate clamping by a piling machine.
[0008] As a further solution of the present invention: an inserting plate is fixed at the bottom of the steel sheet pile structure, and the bottom of the inserting plate is provided with a sharp chamfer to facilitate insertion into the soil.
[0009] As a further solution of the present invention: openings are provided on the sides of the plug-in buckle 1 and the plug-in buckle 2, and the width of the openings is greater than the thickness of the plug-in buckle 1 and the plug-in buckle 2, so as to facilitate buckling.
[0010] Compared with the prior art, the advantages of the present invention are: this patent adds a connecting buckle structure, which is composed of two plug-in buckles, which can facilitate the connection of two steel sheet pile structures at different angles, and adds a triangular support frame structure inside the steel sheet pile structure, which can improve the overall strength of the steel sheet pile structure.

[0021] Combined with attachment Figure 4, it can be seen that in this application, two adjacent steel sheet pile structures 1 can be installed at right angles or small angles through the connection structure, so as to adapt to different application situations;
[0022] Combined with attachment Figure 1 、 3 It can be seen that the structure includes a steel sheet pile structure 1, and two opposite sides of the steel sheet pile structure 1 are fixed with connecting buckle structures, which include a plug-in buckle 1 2 and a plug-in buckle 2 3. A hollow area 1.1 is opened inside the steel sheet pile structure 1, and a plurality of triangular support frame structures 4 are fixed in the hollow area 1.1, which can increase the overall support strength of the steel sheet pile structure 1;
[0023] There is a ninety-degree angle between the plug-in buckle 1 2 and the plug-in buckle 2 3, which is convenient for adapting to different installation angles; a clamping plate 5 is fixed on the top of the steel sheet pile structure 1, which is convenient for clamping by a piling machine; an insertion plate 6 is fixed at the bottom of the steel sheet pile structure 1, and the bottom of the insertion plate 6 is provided with an acute chamfer to facilitate insertion into the soil; openings are provided on the sides of the plug-in buckle 1 2 and the plug-in buckle 2 3, and the width of the opening is greater than the thickness of the plug-in buckle 1 2 and the plug-in buckle 2 3, which is convenient for buckling.
[0024] The working principle of this application is: when installing the steel sheet pile cofferdam, first use the clamping pile driving machine to clamp the steel sheet pile structure 1 at the clamping plate 5, then determine the position, and manually connect the connecting buckle structures on the sides of two adjacent steel sheet pile structures 1. According to the installation needs, you can judge the connection between the plug-in buckle 1 2 and the plug-in buckle 2 3 by yourself. After the connection is completed, it can be inserted into the soil through the pile driving machine.
