[0020] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0021] A combined foundation pit support structure, such as Figure 1 As shown in FIG. 3 , the folding plate 2 is mainly composed of an equipment base 1, a folding plate 2, a rotating hinge seat 3, a telescopic support rod 4, a clamping rod 5, a folding type fitting support structure, etc. One end of the folding plate 2 is hinged to one end of the equipment base 1. Preferably, the folding plate 2 is installed on the equipment base 1 through two rotating hinges 7 spaced apart on the left and right.

[0022] The foldable fitting support structure is mainly composed of a telescopic support rod 4, a clamping rod 5 and a telescopic fitting support assembly. The telescopic fitting support assembly is installed on the rear wall surface of the folding plate 2.

[0023] Two telescopic support rods 4 are arranged at intervals on the left and right, and one end of the telescopic support rod 4 is installed on the front wall of the folding plate 2 through respective rotating hinge seats 3. The clamping rod 5 is horizontally installed at the lower ends of the two telescopic support rods 4. A clamping groove 6 is provided on the upper wall of the equipment base 1 for the clamping rod 5 to be inserted and clamped during operation. During operation, the folding plate 2 is almost vertical to the equipment base 1, and the folding plate 2 is supported by the telescopic support rod 4.

[0024] Anti-skid teeth (not shown in the figure) are arranged on the lower wall of the equipment base 1. The equipment base 1 is used to support the equipment as a whole. At the same time, the anti-skid teeth arranged on the lower wall increase the friction with the ground to prevent the equipment from moving due to force during support.

[0025] A slot 8 for inserting and clamping the clamping rod 5 when folding is provided on one side wall of the equipment base 1 away from the rotating hinge 7. When folding, the telescopic support rod 4 is retracted, the folding plate 2 is folded downward, and the clamping rod 5 is inserted into the slot 8 and clamped.

[0026] The telescopic fitting support assembly is mainly composed of an adjustable telescopic rod 9, a support baffle 10 and a connecting plate 12.

[0027] All the support baffles 10 are arranged at intervals behind the folding plate 2, and each support baffle 10 is connected to the folding plate 2 by a corresponding adjustment telescopic rod 9. Two adjacent support baffles 10 are connected by a connecting plate 12. When adjacent support baffles 10 are pressed against the side walls of the foundation pit with different concave and convex surfaces to cause misalignment, the connecting plate 12 can still ensure that they are connected between the two adjacent support baffles 10. Several adjustment telescopic rods 9 are telescopically fixed by pins 13.

[0028] Preferably, combined with Figure 1 — Figure 5As shown, the width of the connecting plate 12 is greater than the spacing distance between two adjacent supporting baffles 10, a connecting groove 11 corresponding to the connecting plate 12 is provided on the supporting baffle 10, elastic tenons 12a are provided on the upper and lower end surfaces of the connecting plate 12, and long strip slide grooves 11a extending left and right for the elastic tenons 12a to be inserted into are provided on the upper and lower walls of the connecting groove 11.

[0029] The folding plate 2 is rotated and unfolded by rotating the hinge 7, and the telescopic support rod 4 is adjusted so that the clamping rod 5 at the lower end is inserted into the clamping groove 6 for support and fixation, and the telescopic fitting support assembly is adjusted to fit the foundation pit wall surface. By changing the telescopic length of the telescopic rod 9, the support baffle 10 installed thereon is adjusted forward and backward to be combined into the same angle shape as the foundation pit side wall. During adjustment, the connecting plate 12 is inserted into the long strip slide groove 11a extending left and right through the elastic tenon 12a. When the support baffle 10 is adjusted in position, the connecting plate 12 moves in the long strip slide groove 11a to ensure that both ends are stably connected to the support baffle 10. The connection plate 12 ensures the integrity of several support baffles 10, ensures the force effect during support, and further ensures the support safety.
