Description

Technical Field

[0001] This utility model relates to the technical field of anti-buoyancy anchor bolt devices, and in particular to an anti-buoyancy anchor bolt device for raft foundations. Background Technology

[0002] The anti-buoyancy anchor device for raft foundations is a structural measure used to prevent the raft foundation from floating due to the buoyancy of groundwater. It fixes the raft foundation to a deeper and more stable soil or rock layer by installing anchors under or around the foundation. The anchors are usually made of high-strength steel and require drilling and grouting during installation to ensure anchoring force. This device effectively improves the stability and safety of the structure and is particularly suitable for areas with high groundwater levels.

[0003] In existing technologies, anti-buoyancy anchors typically have grouting pipes installed inside. These pipes are inserted into the borehole along with the anchors for easy grouting. However, improper operation during the insertion of the anchors can lead to tilting of the anchors, affecting construction quality. Furthermore, the frequent friction of the grouting pipes against the borehole wall can cause damage to the pipes. Therefore, an anti-buoyancy anchor device for raft foundations is proposed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-buoyancy anchor device for raft foundations, which solves the problem mentioned in the background art that when inserting the anti-buoyancy anchor into the borehole, improper operation may not only cause the anti-buoyancy anchor to tilt, affecting the construction quality, but also cause the grouting pipe to frequently rub against the inner wall of the borehole, which may lead to the risk of grouting pipe breakage.
