[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0024] like Figures 1-5 As shown, this utility model is a foundation pit support structure based on the TRD method, including a first side plate 1, of which there are two. Each side plate 1 has a connecting plate 2 on both sides. The side of the connecting plate 2 away from the first side plate 1 is movably connected to a second side plate 3. The second side plate 3 is movably connected to the connecting plate 2, so that the second side plate 3 can rotate around the connecting plate 2, thereby facilitating the storage of the foundation pit support structure. The first side plate 1 and the second side plate 3 are fixedly connected to each other by connecting members 4. The connecting members 4 can provide stable support between the first side plate 1 and the second side plate 3 respectively. The connecting member 4 includes a U-shaped seat 5, a movable rod 6, a cavity 7, a connecting rod 8, a limiting plate 9, a threaded rod 10, and a connecting pipe 11.

[0025] The U-shaped seat 5 is located on a first side plate 1 and two second side plates 3 on one side of the first side plate 1. The U-shaped seat 5 is movably connected to the movable rod 6 by a pin. The movable rod 6 has a cavity 7 on the side away from the U-shaped seat 5. A connecting rod 8 is inserted into the cavity 7. The connecting rod 8 is movably connected to the movable rod 6, so that the connecting rod 8 can extend and retract inside the movable rod 6. By adjusting the degree of communication between the connecting rod 8 and the movable rod 6, the entire connecting piece 4 can be adjusted, which makes it easier to assemble the connecting piece 4. The side of the connecting rod 8 away from the cavity 7 is fixedly connected to the limiting plate 9. A connecting tube 11 is sleeved on the side of the connecting rod 8 near the limiting plate 9. The connecting tube 11 is movably connected to the connecting rod 8. The first side plate 1 and the second side plate 3 are provided with threaded rods 10 that match the connecting tube 11. The connecting tube 11 can be fixedly connected to the threaded rod 10. Through the interaction between the threaded rod 10 and the connecting tube 11, the connecting piece 4 can support the two first side plates 1 and the second side plates 3.

[0026] The inner wall of the connecting pipe 11 is provided with internal threads matched with the threaded rod 10, and the internal threads of the inner wall of the connecting pipe 11 enable the staff to rotate the connecting pipe 11 when assembling the connecting piece 4, so that the connecting piece 4 is more convenient to install and disassemble through the threaded connection between the connecting pipe 11 and the threaded rod 10.
