The staff uses a tool to rotate the rotating ring 9 so that the second threaded rod 5 and the first threaded rod 4 can move away from each other, and under the effect of thread self-locking, the lengths of the threaded sleeve 3, the first threaded rod 4, and the second threaded rod 5 are kept fixed, thereby realizing the total length adjustment of the threaded sleeve 3, the first threaded rod 4, and the second threaded rod 5, and then the distance between the outer support frame 1 and the inner support frame 2 is changed, thereby realizing the support of the pile bearing by the outer support frame 1.

[0028] In this embodiment, specifically: a slide groove 12 is opened on the base 11, and two groups of slide grooves 12 are set. A clamping plate 13 is slidably connected to the slide groove 12. A bidirectional screw 15 is rotatably connected to the base 11. The bidirectional screw 15 is threadedly connected to the clamping plate 13. The clamping plate 13 is symmetrically arranged in two groups, and the threads of the two groups of clamping plates 13 are set in opposite directions.

[0029] In this embodiment, specifically: a damping rod 20 is fixedly mounted on the support 18, the damping rod 20 is fixedly connected to the base 11, a guide telescopic rod 19 is provided between the support 18 and the base 11, an arc-shaped elastic plate 21 is provided between the support 18 and the base 11, a guide groove 23 is provided on the support 18, sliders 22 are fixedly connected at both ends of the arc-shaped elastic plate 21, the slider 22 is slidably connected inside the guide groove 23, when vibration occurs during construction at the construction site, the vibration of the base 11 causes the arc-shaped elastic plate 21 to deform, the slider 22 slides back and forth in the guide groove 23 to compensate for the deformation of the arc-shaped elastic plate 21 by displacement, and the vibration force is weakened, and at the same time, the reciprocating extension and retraction of the damping rod 20 weakens the energy of the vibration.

[0030] In this embodiment, specifically: the outer support frame 1 and the inner support frame 2 are both arranged in an arc shape, and the threaded sleeve 3, the first threaded rod 4, and the second threaded rod 5 are all arranged in multiple groups and are evenly distributed between the outer support frame 1 and the inner support frame 2.

[0031] In this embodiment, specifically: one end of the bidirectional screw 15 is fixedly connected to a rotating handle 17, and the staff uses a tool to rotate the rotating handle 17, and the rotating handle 17 causes the bidirectional screw 15 to rotate. Since the threads of the two sets of clamps 13 are set in opposite directions, the two sets of clamps 13 can be brought close to each other to clamp and fix the fixing seat 10, so that the outer support frame 1 and the inner support frame 2 can be fixed on the base 11.

[0032] In this embodiment, specifically: a rotating ring 9 is fixedly connected to the threaded sleeve 3 .

[0033] In this embodiment, specifically: a cushion block 16 is fixedly connected to the base 11 , and a plurality of cushion blocks 16 are provided and are evenly distributed on the base 11 .

[0034] In this embodiment, specifically: the bottoms of the outer support frame 1 and the inner support frame 2 are fixedly connected with a fixing seat 10 , and the fixing seat 10 is arranged between the clamping plates 13 .

[0035] In this embodiment, specifically: a layer of anti-slip pad 14 is provided on the inner side of the clamping plate 13 .

[0036] Working principle or structural principle: When excavating and reinforcing, first place the device at the place where reinforcement support is required, and then the staff rotates the rotating ring 9 with a tool so that the second threaded rod 5 and the first threaded rod 4 can move away from each other, and under the effect of thread self-locking, the lengths of the threaded sleeve 3, the first threaded rod 4, and the second threaded rod 5 are kept fixed, thereby realizing the total length adjustment of the threaded sleeve 3, the first threaded rod 4, and the second threaded rod 5, thereby changing the distance between the outer support frame 1 and the inner support frame 2, and realizing the support of the pile bearing by the outer support frame 1;

[0037] During installation, the base 11 is first placed on the support 18, and then the base 11 is fixed to the support 18 by bolts, so that the base 11 is supported under the elasticity of the arc-shaped elastic plate 21 and the damping rod 20. When vibration occurs during construction on the construction site, the vibration of the base 11 causes the arc-shaped elastic plate 21 to deform, and the slider 22 reciprocates in the guide groove 23 to compensate for the deformation of the arc-shaped elastic plate 21 and weaken the vibration force. At the same time, the reciprocating extension and contraction of the damping rod 20 weakens the vibration energy, thereby achieving shock absorption of the support device and ensuring the stability of the support.

[0038] During installation, the fixing seat 10 is placed between the clamps 13, and the staff uses a tool to rotate the rotating handle 17, which causes the bidirectional screw 15 to rotate. Since the threads of the two sets of clamps 13 are set in opposite directions, the two sets of clamps 13 can be brought close to each other to clamp and fix the fixing seat 10, so that the outer support frame 1 and the inner support frame 2 can be fixed on the base 11, thereby completing the splicing and installation of the device.
