Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a rotary drilling pile support structure. Background Technology

[0002] In the construction of high-rise buildings, the foundation construction is a crucial step for the protection and safety of the building. There are many methods for constructing foundation piles, among which rotary drilling rigs are widely used due to their mechanized operation, requiring fewer workers and saving significant labor costs. After the rotary drilling pile hole is dug, a support structure is needed to prevent the inner wall of the hole from collapsing. A search revealed that patent CN219690545U discloses a rotary drilling pile support structure. This structure includes an inner ring, with a connecting plate fixedly connected to one end of the arc-shaped outer wall of the inner ring. A top collar is fixedly connected to the other end of the connecting plate, and a bottom collar is fixedly connected to the end of the connecting plate away from the inner ring. A connector is fixedly installed on the lower surface of the bottom collar, and a pressure-resistant component is provided at the end of the connecting plate away from the inner ring.

[0003] However, in actual use, the applicant found that the length of the rotary drilling pile support structure is positively correlated with the depth of the rotary drilling pile hole. When the rotary drilling pile hole is deeper, the length of the corresponding rotary drilling pile support structure is also longer, which makes it inconvenient for personnel to transport and move the rotary drilling pile support structure. In view of this, we propose a rotary drilling pile support structure. Utility Model Content

[0021] A rotary drilling pile support structure includes a rotary drilling pile support cylinder 1, which includes an anti-collapse support inner cylinder 11. Support ring plates 12 are fixedly connected to the outer wall of the anti-collapse support inner cylinder 11, and several layers of support ring plates 12 are arranged at equal intervals on the outer wall of the anti-collapse support inner cylinder 11. Reinforcing brackets 13 are fixedly connected between adjacent support ring plates 12, and several reinforcing brackets 13 are fixed in a circular array between adjacent support ring plates 12. The reinforcing brackets 13 are X-shaped. The arrangement of the reinforcing brackets 13 is used to connect the several layers of support ring plates 12 on the outer wall of the anti-collapse support inner cylinder 11 together, making the structure of the upper and lower layers of support ring plates 12 more stable. This can further improve the deformation resistance of the inner cylinder 11 of the anti-collapse support, and better support the inner wall of the rotary drilling hole. The top and bottom of the reinforcing bracket 13 are fixedly connected to two adjacent support ring plates 12 respectively. By setting several layers of support ring plates 12 on the outer wall of the inner cylinder 11 of the anti-collapse support, the structure of the inner cylinder 11 of the anti-collapse support can be strengthened. By fixing the reinforcing bracket 13 between two adjacent layers of support ring plates 12, several layers of support ring plates 12 can be connected together, making the structure of the upper and lower layers of support ring plates 12 more stable. This can further improve the deformation resistance of the inner cylinder 11 of the anti-collapse support, and thus better support the inner wall of the rotary drilling hole against collapse.

[0022] The top of the anti-collapse support inner cylinder 11 is fixedly connected to an upper connecting ring plate 14, and the bottom of the anti-collapse support inner cylinder 11 is fixedly connected to a lower connecting ring plate 15.
