[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0022] Please refer to Figures 1-4 The utility model provides a kind of technical solutions: a steel sheet pile support equipment in river water conservancy project, including two groups of sliding rods 1:

[0023] Two groups of sliding rods 1 are installed with installation strip 5 at one end away from each other, and two groups of installation strips 5 are installed with steel plate 8 at one end away from each other.

[0024] Two groups of sliding rods 1 are provided with two groups of limiting rods 2 on one side close to each other, and two groups of limiting rods 2 are oppositely inserted in the inside of sliding rod 1, by inserting limiting rod 2 in the inside of sliding rod 1, the moving range of sliding rod 1 can be effectively limited, prevent its excessive movement or deviate from predetermined track, to increase the stability and reliability of entire structure.

[0025] Fixed bolt 3 is installed on the left side of the upper end of right side sliding rod 1, and fixed block 4 is sleeved with fixed bolt 3 at lower end by screw structure, and a plurality of threaded holes matched with it are evenly provided in the right end of left side sliding rod 1, by adjusting the distance between two groups of sliding rods 1, then fixed bolt 3 is inserted into suitable position threaded hole, and fixed block 4 is installed outside fixed bolt 3 by screw structure, to strengthen the fixing effect of sliding rod 1.

[0026] The two groups of installation bars 5 are provided with installation bolts 6 at the upper and lower ends, and the distal ends of the two groups of sliding rods 1 are provided with matching threaded grooves on the upper and lower sides. By inserting the installation bolts 6 at the upper and lower ends of the installation bars 5 and matching them with the threaded grooves on the sliding rods 1, the connection between the installation bars 5 and the sliding rods 1 can be ensured to be more firm, thereby increasing the stability of the entire structure.

[0027] The two groups of installation bars 5 are provided with multiple groups of reinforcing frames 7, and the reinforcing frames 7 are provided in an X-shaped structure. The X-shaped reinforcing frames 7 can effectively disperse the stress acting on the steel plates 8, reduce the case of excessive stress on a single point, thereby protecting the steel plates 8 from being easily deformed or damaged. The X-shaped structure has good bending resistance and can significantly improve the ability of the entire support structure to resist bending, especially when subjected to lateral pressure. This structure can provide stronger support.

[0028] The distal sides of the two groups of steel plates 8 are uniformly provided with multiple groups of trapezoidal protrusions 9, and the interiors of the two groups of steel plates 8 are provided with reinforcing ribs 10. The design of the trapezoidal protrusions 9 can effectively disperse the stress acting on the steel plates 8, reduce the case of excessive stress on a single point, thereby protecting the steel plates 8 from being easily deformed or damaged. The reinforcing ribs 10 not only enhance the structural strength but also help to disperse wear, thereby prolonging the service life of the steel plate 8 pile support equipment. Due to the reinforcing effect of the trapezoidal protrusions 9 and the reinforcing ribs 10, local damage caused by stress concentration is reduced, thereby reducing the frequency and cost of daily maintenance.

[0029] The distal sides of the two groups of installation bars 5 are oppositely provided with six groups of positioning pieces 11, and the six groups of positioning pieces 11 are installed on the outer sides of the reinforcing ribs 10 through positioning bolts 12. The positioning pieces 11 are fixed on the outer sides of the reinforcing ribs 10 through the positioning bolts 12, ensuring the relative position between the installation bars 5 and the steel plates 8 to be accurate, thereby improving the stability of the entire support structure. Under the action of water flow impact or other external forces, the positioning pieces 11 and the positioning bolts 12 can effectively prevent the installation bars 5 and the steel plates 8 from being displaced, maintaining the integrity of the structure.
