[0023] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Example 1: Please refer to Figures 1 to 6 This utility model provides a technical solution: a high-pressure spray device for dust prevention and reduction during the construction of a large-span deep foundation pit project, comprising: an installation plate 1, a lifting groove 2 on the side of the installation plate 1, a lifting plate 3 inside the lifting groove 2, a positioning plate 4 on the side of the lifting plate 3, a through hole on the side of the positioning plate 4, a positioning hook 5 inside the through hole, a traction rope 6 on the side of the positioning hook 5, a water pipe 7 at the bottom of the traction rope 6, an atomizing nozzle 8 on the side of the water pipe 7, a base plate 9 on the side of the installation plate 1, and a water pump 10 on the surface of the base plate 9; a first upright plate 11, a rotating rod 12 on the side of the first upright plate 11, an auxiliary plate 13 on the surface of the rotating rod 12, and a threaded pipe 14 on the end face of the auxiliary plate 13; a limiting plate 15, a second upright plate 16 on the surface of the limiting plate 15, a support rod 17 on the side of the second upright plate 16, and an adjusting plate 18 on the surface of the support rod 17.

[0025] First, fix the two sets of mounting plates 1, and then fix the traction rope 6 through the two sets of mounting plates 1, thereby fixing the water pipe 7 below the traction rope 6, so that the water pump 10 can be connected to the water pipe 7 through the water delivery pipe. With the cooperation of the mounting plates 1 and the traction rope 6, the water pipe 7 can be easily fixed on the foundation pit slope and muddy and bumpy terrain. Then, with the atomizing nozzles 8 set on the side of the water pipe 7, it is convenient to suppress dust in the air.

[0026] Example 2: Based on Example 1, a water pipe 7 is provided to facilitate dust suppression in the air. The output end of the water pump 10 is connected to the water pipe 7 via a water supply pipe, and the input end of the water pump 10 is connected to the water storage tank. Multiple sets of atomizing nozzles 8 are provided, and the multiple sets of atomizing nozzles 8 are arranged linearly at equal intervals on the surface of the water pipe 7. The lifting trough 2 is in the shape of a "T" plate. A positioning screw 19 is provided on the side of the lifting trough 2, and a positioning nut 20 is screwed onto the surface of the positioning screw 19. A positioning port 21 is opened on the side of the lifting plate 3, and the positioning screw 19 passes through the positioning port 21. The positioning plate 4 is fixedly connected to the side of the lifting plate 3.

[0027] In use, water is first pumped into the water pipe 7 by the water pump 10, and then sprayed out with water mist by the multiple sets of atomizing nozzles 8. The water mist sprayed by the atomizing nozzles 8 can easily suppress dust in the air. When it is necessary to adjust the height of the water pipe 7 for convenient use, the positioning nut 20 can be loosened to adjust the height of the lifting plate 3 in the lifting groove 2. After adjusting to the appropriate height, the positioning nut 20 is tightened to fix the lifting plate 3 after the height is adjusted. Then, the height adjustment of the water pipe 7 can be used to more easily suppress dust. The positioning hook 5 and the positioning plate 4 can also facilitate the disassembly of the water pipe 7.

[0028] Example 3: Based on Example 2, in order to facilitate the fixing of the mounting plate 1, a limiting plate 15 is set. The first upright plate 11 is fixedly connected to the side of the mounting plate 1. The auxiliary plate 13 is rotatably connected to the rotating rod 12. The threaded tube 14 is fixedly connected to the end face of the auxiliary plate 13. The adjusting plate 18 is rotatably connected to the support rod 17. The end face of the adjusting plate 18 is provided with a positioning bearing 22. The inner ring surface of the positioning bearing 22 is fixedly connected with a support screw 23. One end of the support screw 23 is screwed into the threaded tube 14. A positioning cone 24 is provided inside the limiting plate 15.

[0029] When the mounting plate 1 is fixed in use, the positioning cone 24 can be inserted into the ground to fix the limiting plate 15. Then, with the cooperation of the threaded tube 14 and the support screw 23, the side of the mounting plate 1 can be supported to increase the stability of the mounting plate 1. Then, with the cooperation of the positioning bearing 22, the support screw 23 can be rotated, which allows the support screw 23 to move within the threaded tube 14. This makes it easy to adjust the distance between the auxiliary plate 13 and the adjusting plate 18 to adapt to different uneven ground.
