DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 As shown, a protective baffle for bored piles comprises a bottom cover 1, a plurality of fixed directional rollers 101 are fixedly connected on the bottom end of the bottom cover 1 to facilitate the movement of the device, a right cover 2 and a left cover 3 are movably connected on the left and right sides of the bottom cover 1 respectively, a fixed connecting rod is provided on the bottom ends of the bottom cover 1 and the right cover 2 and the left cover 3 and between the plurality of fixed directional rollers 101 to enable the device to be fixed at the hole opening of the bored pile, a handle 102 is fixedly connected on the outer side of the right cover 2 and the left cover 3, the right cover 2 and the left cover 3 can be manually pulled outward by the handle 102 to change the diameter of the baffle, and the handle 102 can also be used to carry and move the device.

[0020] An extension component 4 is provided inside the bottom cover 1 and movably connected with the right cover 2 and the left cover 3. The extension component 4 includes an extension plate 1 401, an extension plate 2 402, a first telescopic buckle 403, a second telescopic buckle 404, and an inner box 405. The right cover 2 and the left cover 3 are respectively connected to one end of the extension plate 1 401 and the extension plate 2 402, and the other end of the extension plate 1 401 and the extension plate 2 402 is connected to the inner box 405. The extension plate 1 401 and the extension plate 2 402 are of retractable design, and the diameter of the extension plate 1 401 and the extension plate 2 402 can be adjusted to match the bored piles of different diameters. The inner diameters of the right cover 2 and the left cover 3 are increased by means of the extension plate 1 401 and the extension plate 2 402, and the first telescopic buckle 403 and the second telescopic buckle 404 are connected on both sides of the extension plate 1 401 and the extension plate 2 402. At the same time, telescopic openings are opened on both sides of the bottom cover 1 and parallel to the first telescopic buckle 403 and the second telescopic buckle 404. There are two groups of telescopic openings, both of which can accommodate the first telescopic buckle 403 and the second telescopic buckle 404. The diameters of the extension plate 1 401 and the extension plate 2 402 can be adjusted by pressing the positions of the first telescopic buckle 403, the second telescopic buckle 404 and the telescopic openings from the outside.

[0021] The bottom cover 1 is fixedly connected with an inner box 405, and the right cover 2 and the left cover 3 are connected with an extension mechanism 5. There are multiple extension mechanisms 5, and the symmetrical design is more beautiful. The extension mechanism 5 includes a recycling groove 501, a coordination shaft 502, a protective strip 503, a reflective sheet 504, and a support frame 505. A coordination shaft 502 is connected to one side of the recycling groove 501, and a protective strip 503 is movably connected to the coordination shaft 502. The coordination shaft 502 can drive the protective strip 503 to rotate 90 degrees, so that the protective strip 503 extends upward, so that the baffle protection reminder mode is increased. A reflective sheet 504 is attached to the protective strip 503, and the reflective sheet 504 is attached to both sides of the protective strip 503. At the same time, because the bottom cover 1 forms a circular baffle with the right cover 2 and the left cover 3, so the length of the protective strip 503 is inconsistent, and the reflective sheet 504 changes according to the length of the protective strip 503. The reflective sheet 504 is convenient for improving the visibility of the baffle when it is used at night or in bad weather. A support frame 505 is connected to the side below the protective strip 503 and away from the coordination axis 502. The support frame 505 is a rebound design and can be propped up or laid flat to make the protective strip 503 more stable. The support frame 505 and both sides of the coordination axis 502 are against the protective strip 503, which makes the protective strip 503 more stable and can also prevent the support frame 505 from being blown down when used in bad weather.

[0022] To summarize, the use process of the device is as follows: first, the device is moved to the use position using the handle 102 or the fixed directional roller 101, and then the bottom cover 1, the right cover 2, and the left cover 3 are moved according to the size of the hole, by pulling the handles on one side of the right cover 2 and the left cover 3, and pressing the first telescopic buckle 403 and the second telescopic buckle 404, so that the first telescopic buckle 403 and the second telescopic buckle 404 are expanded and buckled in the telescopic opening, thereby expanding or reducing the internal diameter of the right cover 2 and the left cover 3, and then covering the hole of the artificially dug pile, and at the same time, using pressure to insert the fixed connecting rod into the soil to fix the device as a whole, and then manually pulling the protective strip 503 out of the recovery groove 501, so that the protective strip 503 is perpendicular to the recovery groove 501, and the support frame 505 on one side of the protective strip 503 is propped up, and finally the artificially dug pile can be protected.
