[0017] See also Figure 1-Figure 2 The utility model provides a technical solution: a foundation pit retaining structure, including a panel 1, a side of the panel 1 away from the foundation pit is slidably connected with a fixed plate 11, and also includes a slide rod 13 and a nut 14, the slide rod 13 is horizontally fixedly installed on the side of the fixed plate 11 close to the panel 1, and a slide groove 12 is vertically opened on one side of the panel 1, and the number of the slide grooves 12 is two groups, and the two groups of slide grooves 12 are respectively opened on the front and rear sides of the panel 1, and the number of the slide rod 13 is two groups, and the two groups of slide rods 13 are slidably connected with the two groups of slide grooves 12 respectively.

[0018] In this technical solution, a sliding groove 12 vertically opened on the outer side of the enclosure 1 is slidably connected with a sliding rod 13 horizontally fixedly installed on one side of the fixed plate 11, so that the staff can adjust the connection position of the enclosure 1 and the fixed plate 11 according to the depth of the foundation pit.

[0019] In this embodiment, an external thread 15 is provided on the outer side of the slide rod 13 , and the nut 14 is threadedly connected to the slide rod 13 via the external thread 15 . The nut 14 is pressed against the outer side of the enclosure 1 , and the size of the nut 14 matches that of the slide groove 12 .

[0020] In this technical solution, the nut 14 on the outside of the sliding rod 13 is rotated and pressed against the outside of the enclosure 1, so that the fixed plate 11 on the outside of the enclosure 1 can be limited and fixed.

[0021] In this embodiment, a fixing hole 16 is formed through the upper surface of the fixing plate 11, and the fixing plate 11 is fixedly connected to the top of the foundation pit through a pin 17 passing through the fixing hole 16.
