[0025] See also Figures 1 to 5 The utility model provides a technical solution: a detachable support structure for a deep foundation pit.

[0026] Embodiment 1:

[0027] The arc surface of the horizontal bracket 1 is sleeved with a mounting ring 2, and the arc surface of the mounting ring 2 is fixed with a vertical bracket 3. A storage groove 13 is provided inside the vertical bracket 3, and a notch 14 is provided at the end of the storage groove 13. A baffle 12 is provided on the surface of the notch 14, and a telescopic bracket 7 is fixed on the surface of the baffle 12. The telescopic bracket 7 can be adjusted to the required support replacement length to realize the cyclic use of the support, and the mounting ring 2 is fixed on the end surface of the telescopic bracket 7;

[0028] A positioning block 8 is fixed to the end surface of the screw 5, and a rotating wheel 9 is fixed to the surface of the positioning block 8. The rotation of the rotating wheel 9 will drive the screw 5 to rotate. Since the threaded hole 11 is opposite to the spiral of the screw 5, the rotation of the screw 5 will cause the connecting rod 10 to move. The connecting rod 10 is sleeved on the surface of the screw 5, and the threaded hole 11 is opened on the surface of the connecting rod 10. Connecting sleeves 6 are fixed to the two side ends of the connecting rod 10, and a fixing block 4 is sleeved on the surface of the positioning block 8. The side surface of the fixing block 4 is opened with an annular groove 16, and the arc surface of the inner wall of the annular groove 16 is opened with a through hole 15.

[0029] Embodiment 2:

[0030] On the basis of the first embodiment, in order to realize the detachable support, the connecting sleeve 6 is provided with multiple groups, and the multiple groups of connecting sleeves 6 are symmetrically distributed on the side surface of the connecting rod 10, and the telescopic bracket 7 is provided with multiple groups, and the multiple groups of telescopic brackets 7 are symmetrically distributed, and the telescopic bracket 7 corresponds to the connecting sleeve 6, and the telescopic bracket 7 is clamped in the connecting sleeve 6, and the two are fixedly connected. The connecting rod 10 is welded to the surface of the telescopic bracket 7 through the connecting sleeve 6, so the movement of the connecting rod 10 will drive the telescopic bracket 7 to move;

[0031] There are multiple groups of storage slots 13, which are symmetrically distributed inside the vertical bracket 3, and the telescopic bracket 7 corresponds to the storage slots 13, and the telescopic bracket 7 is clamped in the storage slots 13, and the two are movably connected;

[0032] The size of the baffle 12 is the same as that of the storage groove 13, the size of the notch 14 is the same as that of the telescopic bracket 7, and the size of the baffle 12 is larger than that of the telescopic bracket 7, and the baffle 12 corresponds to the storage groove 13, and the baffle 12 is stuck in the storage groove 13, so the baffle 12 will not fall out of the storage groove 13, and the telescopic bracket 7 will not fall out of the storage groove 13 completely;

[0033] The size of the positioning block 8 is the same as that of the through hole 15, and the size of the screw 5 is the same as that of the annular groove 16, but the size of the positioning block 8 is larger than that of the screw 5, and the positioning block 8 corresponds to the through hole 15, and the positioning block 8 is stuck in the through hole 15, and the two are movably connected, so the positioning block 8 will not fall out of the annular groove 16, and the screw 5 will not move horizontally.

[0034] In actual use, this structure can be recycled. When it is necessary to replace the support, the position between the vertical support 3 and the horizontal support 1 is adjusted by rotating the bolts on the mounting ring 2. When adjusted to the required position, the two are fixed by the combination of bolts and nuts, and the rotating wheel 9 is rotated. The rotation of the rotating wheel 9 will drive the screw 5 to rotate. Since the threaded hole 11 is opposite to the spiral of the screw 5, the rotation of the screw 5 will cause the connecting rod 10 to move. The connecting rod 10 is welded to the surface of the telescopic support 7 through the connecting sleeve 6, so the movement of the connecting rod 10 will drive the telescopic support 7 to move. When the telescopic support 7 moves to the position required for replacing the support, stop rotating the rotating wheel 9, thereby realizing the recycling of the support. This structure is simple and easy to operate. The support can be disassembled by the nut on the mounting ring 2, and the support can be adjusted to the required support for replacing the support by the nut on the mounting ring 2 and the rotating wheel 9, thereby realizing the recycling of the support, which is beneficial to improving its use effect.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
