[0025] Example: Figure 1-5As shown, this utility model provides a stepped combined support device for deep foundation pits, including a bottom support component 1, a top support component 2 on the top of the bottom support component 1, a first connecting component 3 between the bottom support component 1 and the top support component 2, and a stabilizing rod 4 between the bottom support component 1 and the top support component 2. The bottom support component 1 and the top support component 2 are distributed in a stepped manner. In specific use, an appropriate number of top support components 2 can be selected according to the depth of the deep foundation pit, so that the bottom support component 1 and multiple top support components 2 are combined in a stepped manner, thereby enabling close-range support for sloping deep foundation pits and improving the support effect of deep foundation pits.

[0026] The bottom support component 1 includes multiple evenly distributed longitudinal support rods 11. Connecting crossbars 12 are provided between the longitudinal support rods 11. The longitudinal support rods 11 and the connecting crossbars 12 are vertically distributed. Supporting crossbars 13 are also provided between the longitudinal support rods 11. The longitudinal support rods 11 and the supporting crossbars 13 are vertically distributed, as are the connecting crossbars 12 and the supporting crossbars 13. Each supporting crossbar 13 has a support plate 14 at its end away from the longitudinal support rod 11, and a movable insert is provided on the support plate 14. With support rods 15, when in use, multiple support longitudinal rods 11 in the bottom support member 1 are inserted into the foundation of the deep foundation pit, and the support plate 14 is made to contact the side wall of the deep foundation pit. The support rods 15 are then inserted into the deep foundation pit. The deep foundation pit is supported by the support plate 14, support rods 15, support longitudinal rods 11, connecting cross rods 12, and support cross rods 13. Second connectors 5 are provided between the support longitudinal rods 11 and the connecting cross rods 12, and between the support longitudinal rods 11 and the support cross rods 13.

[0027] The second connecting member 5 includes a first connecting sleeve frame 51 and a second connecting sleeve frame 52. A connecting column 53 is fixedly installed between the first connecting sleeve frame 51 and the second connecting sleeve frame 52. The first connecting sleeve frame 51 and the second connecting sleeve frame 52 are vertically distributed. The supporting longitudinal rod 11 moves through the first connecting sleeve frame 51, and the connecting cross rod 12 moves through the second connecting sleeve frame 52. The opposite ends of the first connecting sleeve frame 51 and the second connecting sleeve frame 52 are threaded with first fixing bolts 54. The ends of the first fixing bolts 54 respectively contact the outer sides of the supporting longitudinal rod 11 and the connecting cross rod 12. The second connecting member 5 is used to combine and fix the supporting longitudinal rod 11 and the connecting cross rod 12, thereby facilitating the disassembly of the supporting longitudinal rod 11 and the connecting cross rod 12, and facilitating the selection of appropriate lengths of supporting longitudinal rod 11 and connecting cross rod 12 for combination and connection according to the support area.

[0028] The connection method of the supporting longitudinal rod 11 and the supporting transverse rod 13 is the same as that of the supporting longitudinal rod 11 and the connecting transverse rod 12. The supporting transverse rod 13 moves through the corresponding second connecting sleeve 52. The end of the first fixing bolt 54 contacts the outside of the supporting transverse rod 13. The second connector 5 is used to connect and fix the supporting longitudinal rod 11 and the connecting transverse rod 12, which facilitates the disassembly of the supporting longitudinal rod 11 and the supporting transverse rod 13, and facilitates the selection of a suitable length of supporting longitudinal rod 11 and supporting transverse rod 13 for combination connection according to the support area.

[0029] A fixing frame 141 is fixedly installed on the side of the support plate 14 near the support crossbar 13. The end of the support crossbar 13 away from the support longitudinal bar 11 is movably locked in the fixing frame 141. A second fixing bolt 142 is threaded on the top of the fixing frame 141. The end of the second fixing bolt 142 contacts the support crossbar 13 to lock and fix the support plate 14 and the support crossbar 13.

[0030] The structure of the top support 2 is the same as that of the bottom support 1. The structure of the first connector 3 is the same as that of the second connector 5. The bottom support 1 is movably inserted through the second connecting sleeve 52 in the first connector 3 via the support crossbar 13. The top support 2 is movably inserted through the first connecting sleeve 51 in the first connector 3 via the support longitudinal bar 11. The end of the first fixing bolt 54 in the first connector 3 is respectively in contact with the outer side of the support longitudinal bar 11 and the support crossbar 13. The first connector 3 is used to connect and fix the bottom support 1 and the top support 2 together, so that the bottom support 1 and the top support 2 are combined in a stepped manner.

[0031] The stabilizing rod 4 is inclined; the two ends of the stabilizing rod 4 are respectively connected to the connecting crossbar 12 in the bottom support 1 and the top support 2 by a third connecting member 6; the structure of the third connecting member 6 is the same as that of the second connecting member 5. The two ends of the stabilizing rod 4 movably pass through the first connecting sleeve frame 51 in the third connecting member 6, and the connecting crossbar 12 movably passes through the second connecting sleeve frame 52 in the third connecting member 6. The ends of the first fixing bolts 54 in the third connecting member 6 respectively contact the outer sides of the stabilizing rod 4 and the connecting crossbar 12. The third connecting member 6 is used to connect and fix the stabilizing rod 4 and the connecting crossbar 12 in the bottom support 1 and the top support 2. Due to the inclined setting of the stabilizing rod 4, the bottom support 1, the top support 2 and the stabilizing rod 4 form a triangular structure, which further increases the combined stability of the bottom support 1 and the top support 2, thereby improving the support stability and support effect of the bottom support 1 and the top support 2 for the deep foundation pit.

[0032] Working principle: When in use, select an appropriate number of top support components 2 according to the depth of the deep foundation pit, so that the bottom support component 1 and multiple top support components 2 are combined in a stepped manner.

[0033] Multiple support longitudinal rods 11 in the bottom support component 1 are inserted into the foundation of the deep foundation pit, and the support plate 14 is made to contact the side wall of the deep foundation pit. The support insert rod 15 is inserted into the deep foundation pit. The deep foundation pit is supported by the support plate 14, the support insert rod 15, the support longitudinal rod 11, the connecting horizontal rod 12, and the support horizontal rod 13.

[0034] The second connector 5 is used to connect and fix the supporting longitudinal rod 11 and the connecting horizontal rod 12, which facilitates the disassembly of the supporting longitudinal rod 11 and the connecting horizontal rod 12, and allows for the selection of appropriate lengths of supporting longitudinal rod 11 and connecting horizontal rod 12 for combination and connection according to the support area. The second connector 5 is also used to connect and fix the supporting longitudinal rod 11 and the connecting horizontal rod 12, which facilitates the disassembly of the supporting longitudinal rod 11 and the support horizontal rod 13, and allows for the selection of appropriate lengths of supporting longitudinal rod 11 and support horizontal rod 13 for combination and connection according to the support area, thereby improving the flexibility of deep foundation pit support.

[0035] Using the first connector 3, the bottom support 1 and the top support 2 are combined and fixed, so that the bottom support 1 and the top support 2 are combined in a stepped manner.

[0036] Then, the third connector 6 is used to connect and fix the stabilizing rod 4 and the connecting crossbar 12 in the bottom support 1 and the top support 2. Since the stabilizing rod 4 is inclined, the bottom support 1, the top support 2 and the stabilizing rod 4 form a triangular structure, which further increases the combined stability of the bottom support 1 and the top support 2, thereby improving the support stability and support effect of the bottom support 1 and the top support 2 for the deep foundation pit.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
