Description

A foundation reinforcement device Technical Field

[0001] This utility model belongs to the field of foundation reinforcement technology, and specifically relates to a foundation reinforcement device. Background Technology

[0002] By drilling pile holes in the foundation, placing a steel cage, and pouring concrete, the foundation can be effectively reinforced. Currently, the steel cages used for foundation reinforcement are only made of vertical steel bars and horizontal steel rings tied together. Although the diameter of the pre-dug pile hole is larger than the diameter of the steel cage, with a 10-centimeter edge gap, during actual placement, due to tilting or local deformation during the lowering process, there is contact friction between the steel cage and the inner wall of the pile hole when the steel cage is placed into the pile hole, making it difficult to lower the steel cage smoothly. Summary of the Invention

[0003] Disadvantages. This utility model provides a foundation reinforcement device that can reduce the resistance encountered when lowering the vertical rods and horizontal rings of the steel cage, and can easily remove the outer barrier sleeve from the pile hole.

[0004] This utility model provides the following technical solution: a foundation reinforcement device, comprising a steel cage vertical rod and a steel cage horizontal ring, wherein an outer barrier sleeve is fitted on the outer side of the steel cage vertical rod, and a plurality of inner limiting sleeves are fixedly connected to the inner wall of the outer barrier sleeve, a bending adjustment ring is fixedly connected to the bottom end of the inner limiting sleeve, and a rigid limiting sleeve is fixedly connected to the bottom end of the bending adjustment ring, wherein detachable limiting ropes are inserted into the inner limiting sleeve, the bending adjustment ring, and the rigid limiting sleeve, and the ends of the plurality of detachable limiting ropes are fixedly connected.

[0005] The bottom end of the vertical rod of the steel cage is fixedly connected to an inclined guide rod, which is bent inward.

[0006] The outer wall of the outer barrier sleeve is fixedly connected with an outer lubricating pad, and the outer walls of the inner limiting sleeve, the bending adjustment ring, and the rigid limiting sleeve are fixedly connected with an inner lubricating pad.

[0007] The outer wall of the outer barrier sleeve is fixedly connected to a towing rope, which extends upwards.

[0008] Among them, several of the detachable limiting ropes are fixedly connected to the top of a disassembly traction rope, and the disassembly traction rope extends upward from the vertical rod of the steel cage.

[0009] The rigid limiting sleeve is hinged to the inner limiting sleeve through the bending adjustment ring, and the rigid limiting sleeve abuts against the horizontal ring of the bottommost steel cage.

[0010] The length of the rigid limiting sleeve is less than the length of the inclined guide rod.

[0011] The beneficial effects of this utility model are as follows: the outer barrier sleeve fitted on the outside of the vertical rod of the rebar cage can prevent the vertical rod and horizontal ring of the rebar cage from directly contacting the hole wall, thereby reducing the resistance encountered by the vertical rod and horizontal ring of the rebar cage when lowering. The outer barrier sleeve is limited by the bending adjustment ring and the rigid limiting sleeve in conjunction with the detachable limiting rope, which can prevent the outer barrier sleeve from falling off during the lowering of the vertical rod and horizontal ring of the rebar cage. Furthermore, the outer barrier sleeve can be separated from the vertical rod and horizontal ring of the rebar cage by removing the detachable limiting rope, so as to conveniently remove the outer barrier sleeve from the pile hole.

[0012] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

Detailed Implementation

[0018] Please refer to Figures 1-4. This utility model provides the following technical solution: a foundation reinforcement device, including a steel cage vertical rod 1 and a steel cage horizontal ring 11. An outer barrier sleeve 2 is sleeved on the outside of the steel cage vertical rod 1. Several inner limiting sleeves 21 are fixedly connected to the inner wall of the outer barrier sleeve 2. A bending adjustment ring 22 is fixedly connected to the bottom end of the inner limiting sleeve 21. A rigid limiting sleeve 23 is fixedly connected to the bottom end of the bending adjustment ring 22. A detachable limiting rope 3 is inserted into the inner limiting sleeve 21, the bending adjustment ring 22 and the rigid limiting sleeve 23. The ends of several detachable limiting ropes 3 are fixedly connected.

[0019] In this implementation plan: After the workers complete the weaving of the vertical rod 1 and horizontal ring 11 of the rebar cage, they pass multiple detachable limiting ropes 3 through multiple inner limiting sleeves 21. Then, they put the outer blocking sleeve 2 on the outside of the vertical rod 1 and horizontal ring 11 of the rebar cage. Next, they tie one end of several detachable limiting ropes 3 near the inclined guide rod 12 together, and tie the disassembly traction rope 31 to the multiple detachable limiting ropes 3 together. Then, by pulling the movable end of the detachable limiting ropes 3, they taut the multiple detachable limiting ropes 3 and tie the other end of the multiple detachable limiting ropes 3 together. The rigid limiting sleeve 23 bends inward under the action of the detachable limiting ropes 3. The position of the rigid limiting sleeve 23 is adjusted to fit with the lowest horizontal ring 11 of the rebar cage. Then, the device is vertically lowered into the pile hole. During the lowering process, the outer blocking sleeve 2 is used to guide the movement of the ropes. The barrier sleeve 2 prevents the vertical rod 1 and horizontal ring 11 of the steel cage from directly contacting the hole wall, thereby reducing the resistance encountered when the vertical rod 1 and horizontal ring 11 of the steel cage are lowered. The detachable limiting rope 3 can limit the rigid limiting sleeve 23. The rigid limiting sleeve 23 is in a bent state to limit the outer barrier sleeve 2, which can prevent the outer barrier sleeve 2 from falling off during the lowering of the vertical rod 1 and horizontal ring 11 of the steel cage. After the vertical rod 1 and horizontal ring 11 of the steel cage are installed, the workers spread out the upper end of the detachable limiting rope 3, and then pull the detachable limiting rope 3 out of the inner limiting sleeve 21 and take it out of the pile hole by pulling the traction rope 31. Then the workers pull the outer barrier sleeve 2 out of the pile hole. During the removal process, the workers operate above the pile hole the whole time, which is more convenient. Then the workers inject grout into the pile hole to reinforce the foundation.

[0020] An inclined guide rod 12 is fixedly connected to the bottom end of the vertical rod 1 of the steel cage. The inclined guide rod 12 is bent inward. The inclined guide rod 12 can play a guiding role, so as to avoid the bottom end of the steel cage directly hitting the hole wall and being unable to move down smoothly.

[0021] An outer lubrication pad 24 is fixedly connected to the outer wall of the outer barrier sleeve 2, and an inner lubrication pad 25 is fixedly connected to the outer wall of the inner limiting sleeve 21, the bending adjustment ring sleeve 22, and the rigid limiting sleeve 23. By setting the outer lubrication pad 24 and the inner lubrication pad 25, a lubrication function can be achieved. The outer lubrication pad 24 can reduce the resistance encountered when the vertical rod 1 and the horizontal ring 11 of the steel cage are lowered, and the inner lubrication pad 25 can reduce the frictional resistance between the outer barrier sleeve 2 and the steel cage when the outer barrier sleeve 2 is pulled out of the pile hole.

[0022] The outer wall of the outer barrier sleeve 2 is fixedly connected with a drag rope 26, which extends upward. By setting the drag rope 26, it is easy for external machines or personnel to drag the outer barrier sleeve 2, so as to conveniently remove the outer barrier sleeve 2 from the pile hole.

[0023] Several detachable limiting ropes 3 are fixedly connected to the top of a disassembly traction rope 31, and the disassembly traction rope 31 extends upward out of the steel cage vertical rod 1; by setting the disassembly traction rope 31, it is convenient for workers to pull out the detachable limiting rope 3 from the lower opening of the rigid limiting sleeve 23 above the pile hole.

[0024] The rigid limiting sleeve 23 is hinged to the inner limiting sleeve 21 via the bending adjustment ring 22. The rigid limiting sleeve 23 abuts against the bottommost horizontal ring 11 of the steel cage. The rigid limiting sleeve 23 is hinged to the inner limiting sleeve 21 via the bending adjustment ring 22. When it is necessary to limit the outer blocking sleeve 2, the rigid limiting sleeve 23 is in a horizontal state. When it is necessary to pull out the outer blocking sleeve 2, the rigid limiting sleeve 23 flips outward to release the limitation of the outer blocking sleeve 2.

[0025] The length of the rigid limiting sleeve 23 is less than the length of the inclined guide rod 12; the inclined guide rod 12 is longer to provide sufficient space for the flipping of the rigid limiting sleeve 23, so as to avoid the outer blocking sleeve 2 being unable to be removed due to the restriction of the flipping of the rigid limiting sleeve 23.

[0026] The working principle and usage process of this utility model are as follows: After the workers have completed the weaving of the vertical rod 1 and horizontal ring 11 of the rebar cage, multiple detachable limiting ropes 3 are passed through multiple inner limiting sleeves 21 respectively. Then, the outer blocking sleeve 2 is placed on the outside of the vertical rod 1 and horizontal ring 11 of the rebar cage. Next, one end of several detachable limiting ropes 3 near the inclined guide rod 12 is tied together, and the disassembly traction rope 31 is tied together with the multiple detachable limiting ropes 3. Then, by pulling the movable end of the detachable limiting ropes 3, the multiple detachable limiting ropes 3 are taut. The other ends of multiple detachable limiting ropes 3 are tied together. The rigid limiting sleeve 23 is bent inward under the action of the detachable limiting ropes 3. The position of the rigid limiting sleeve 23 is adjusted to fit with the bottom horizontal ring 11 of the steel cage. Then the device is vertically placed into the pile hole. After the steel cage vertical rod 1 and the steel cage horizontal ring 11 are installed, the workers spread out the upper end of the detachable limiting rope 3. Then, the detachable limiting rope 3 is pulled out from the inner limiting sleeve 21 by pulling the traction rope 31 and taken out from the pile hole. Then the workers pull out the outer blocking sleeve 2 from the pile hole.
