DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1: Refer to the attached instructions Figure 1-4 , a foundation pit retaining structure of the utility model includes a column 1, see Figure 2 , a channel steel sheet pile 2 is provided on one side of the column 1, and a first support plate 3 and a first support member 4 are provided on one side of the channel steel sheet pile 2, see Figure 3, a first threaded rod 5 is fixedly connected to one side of the first support member 4, and the first threaded rod 5 is connected to the inside of the first support plate 3 by a thread. A slot 6 is provided on one side of the first support plate 3 and the first support member 4. A supporting inner rod 7 is inserted into the slot 6 of the first support member 4. The outer wall of the supporting inner rod 7 is slidably connected to the supporting outer sleeve 8. A placement groove 9 is provided inside the supporting inner rod 7. A gasket 10 (a plurality of gaskets 10 of different thicknesses are provided) is inserted into the placement groove 9. The gasket 10 is provided on one side of the supporting outer sleeve 8;

[0022] The outer wall of the first support member 4 is rotatably connected to the top rod 11, and the outer wall of the top rod 11 is provided with a connecting member 12. The interior of the connecting member 12 is slidably connected to a fixed plate 13, and the fixed plate 13 is provided on one side of the top rod 11. One side of the fixed plate 13 is rotatably connected to a second threaded rod 14, and the second threaded rod 14 is connected to the interior of the connecting member 12 through threads. One end of the second threaded rod 14 is fixedly connected to a connecting head 15, and a second support member 16 is fixedly installed on one side of the connecting member 12. One side of the second support member 16 is connected to a second support plate 17 through threads (the length of the first support plate 3 and the second support plate 17 needs to be adjusted according to the size of the foundation pit enclosure). The second support member 16 and the second support plate 17 are provided on one side of the channel steel sheet pile 2.

[0023] It should be noted that, when the staff needs to enclose the foundation pit, they first fix the four columns 1 at the four corners of the foundation pit, and then fix the channel steel sheet piles 2 plugged together inside the foundation pit, and set the first support member 4, the first support plate 3, the second support member 16, and the second support plate 17 to form an enclosure inside the channel steel sheet pile 2. After that, the staff can insert the support inner rod 7 and the support outer sleeve 8 into the two slots 6 corresponding to the first support member 4, and insert a suitable gasket 10 into the placement slot 9 of the support inner rod 7 until the support outer sleeve 8, the support The support rod formed by the inner support rod 7 and the gasket 10 stops after the length is the same as the distance between the two corresponding first support members 4. At this time, the inner support rod 7 and the outer support sleeve 8 will support and fix the channel steel sheet piles 2 on both sides of the interior of the foundation pit, preventing the channel steel sheet piles 2 from being displaced, resulting in problems with the enclosure of the foundation pit, causing the displacement of the foundation pit and affecting the subsequent construction of the staff. It is convenient for the staff to support and fix the enclosure of steel sheet piles 2 of different sizes, and the staff does not need to make support rods of appropriate length according to the size of the enclosure of the channel steel sheet piles 2, thereby improving the staff's use experience;

[0024] Furthermore, when the staff needs to support and fix the channel steel sheet piles 2 on the other two sides of the foundation pit, the top rod 11 can be rotated into the connecting piece 12 on the second support piece 16, and then the crowbar (not shown) can be inserted into the inside of the connecting head 15, and the connecting head 15 can be rotated by the crowbar to make the connecting head 15 drive the second threaded rod 14 to rotate, and then the second threaded rod 14 can slide along the inside of the connecting piece 12 and push the fixing plate 13 to move in the direction of the top rod 11, so that the fixing plate 13 pushes and limits the top rod 11 that rotates into the inside of the connecting piece 12, and allows the top rod 11 to press on one side of the second support piece 16 to support and fix the second support piece 16, so as to achieve the effect of quickly supporting and fixing the other two sides of the foundation pit, making it convenient for the staff to enclose the foundation pit and prevent the foundation pit from being displaced, which affects the subsequent construction of the staff.
