[0020] Figure 4 The schematic diagram of the channel side wall support device provided by the utility model in the actual application state. The channel side wall support device includes: two support plates 9, and also includes a long slot box 1, a main handle and two auxiliary handles are fixedly installed on the top of the long slot box 1, and the two auxiliary handles are respectively located on both sides of the main handle, and two sliders 2 are slidably installed in the long slot box 1, and a rectangular sleeve 4 is provided at the bottom of the two sliders 2, and a cross plate 5 is fixedly installed at the bottom of the two rectangular sleeves 4, and an oblique reinforcing rod is fixedly installed on the top of the cross plate 5, and the end of the oblique reinforcing rod away from the cross plate 5 is fixedly connected to the rectangular sleeve 4, and the two support plates 9 are respectively rotatably installed on the ends of the two cross plates 5 away from each other, and a plurality of anti-slip convex grooves are evenly spaced on the outer wall of the side of the two support plates 9 away from each other, and the bottom of the two cross plates 5 are both rotatably installed with a connecting shaft 6, and the two connecting shafts 6 are both rotatably sleeved with a rotating cylinder 7, and the two rotating cylinders 7 are both threadedly installed with a threaded rod 8, and specifically, a nut is fixedly installed in the rotating cylinder 7, and the threaded rod 8 penetrates the nut and is connected to the inner wall of the nut. The two ends of the two threaded rods 8 are screwed together, and the ends away from each other are rotatably connected to the two support plates 9 respectively. The same bidirectional screw rod 14 is rotatably installed on the inner walls of both sides of the long groove box 1. The bidirectional screw rod 14 passes through the two sliders 2 and is threadedly connected to the two sliders 2. The two sliders 2 are driven to move toward or away from each other by rotating the bidirectional screw rod 14, so that the distance between the two support plates 9 can be increased or decreased. Hexagonal heads 15 are fixedly installed at both ends of the bidirectional screw rod 14, which is convenient for using a wrench to screw the bidirectional screw rod 14. In order to ensure the stability of the support, a fixing rod 10 is fixedly installed on the outer walls of both sides of the two rectangular sleeves 4. A sleeve 11 is slidingly sleeved on the fixing rod 10, and a first locking screw is threadedly installed on the sleeve 11. The sleeve 11 and the fixing rod 10 are fixed by screwing the first locking screw. A pad 12 is fixedly installed on the bottom end of the sleeve 11, and four tamping nails 13 are movably installed on the pad 12.

[0021] In this embodiment, in order to facilitate the operator to use the hexagonal wrench to screw the bidirectional screw rod 14, a hexagonal groove is provided in the hexagonal head 15.

[0022] In this embodiment, in order to raise the height of the long groove box 1, rectangular rods 3 are fixedly installed at the bottom of the two sliders 2. The bottom ends of the two rectangular rods 3 extend into the two rectangular sleeves 4 respectively and are slidingly connected to the inner walls of the corresponding rectangular sleeves 4. A second locking screw is threadedly installed on the rectangular sleeves 4.

[0023] The working principle of the channel side wall support device provided by the utility model is as follows:

[0024] When in use, first adjust the distance between the two support plates 9 according to the width of the channel. When adjusting, use an open-end wrench or an Allen wrench to screw the bidirectional screw rod 14. The bidirectional screw rod 14 will drive the two sliders 2 to move closer to or away from each other during forward or reverse rotation. The two sliders 2 will respectively drive the corresponding rectangular sleeves 4, cross plates 5, support plates 9 and other components to move accordingly, so that the distance between the two support plates 9 can be roughly adjusted to an appropriate distance. Then, the inclination of the two support plates 9 can be adjusted according to the slope of the inner walls on both sides of the channel. When adjusting, rotate the rotating drum 7 clockwise or counterclockwise. During the rotation of the rotating drum 7, the threaded rod 8 will be driven to extend outward or retract inward. Driven by the threaded rod 8, the inclination angle of the support plate 9 can be changed. When the inclination angle of the support plate 9 is When the slope is consistent with the slope of the inner wall of the corresponding channel, the two support plates 9 are fitted with the corresponding inner wall of the channel by rotating the two-way screw rod 14, and then the four first locking screws are rotated counterclockwise in turn to release the fixation between the fixing rod 10 and the sleeve 11. Under the action of gravity, the four sleeves 11 will slide downward, and the four pads 12 will contact the bottom inner wall of the channel. Then, the tamping nails 13 are inserted into the round holes on the pads 12, and the tamping nails 13 are tamped into the soil with a hammer. Finally, the four first locking screws are tightened clockwise in turn. In this way, the entire channel side wall support device is reliably fixed. Under the support of the two support plates 9, the side wall of the channel can be well prevented from collapsing. At the same time, a "passageway" is formed between the two rectangular sleeves 4 to facilitate the passage of construction personnel.

[0025] In addition, after the channel side wall support device is fixed, the relevant user can also adjust the long groove box 1 upward to increase the height of the "channel" and further improve the convenience of construction workers to pass through. When adjusting, turn the two second locking screws counterclockwise in turn to release the fixation between the rectangular rod 3 and the rectangular sleeve 4, and then lift the long groove box 1 upward. After the height is raised to an appropriate level, tighten the two second locking screws clockwise in turn.
