Description

Technical Field

[0001] The present application relates to the technical field of anchor rods, and in particular to an anti-floating anchor rod. Background Art

[0002] Anti-floating anchor is a kind of anti-floating measure for underground structure of construction project, which is related to the height and change of groundwater level. It is opposite to the force direction of compression pile. Anti-floating anchor is different from general foundation pile and has its own unique performance. The biggest difference between it and general foundation pile is that foundation pile is usually compression pile, and the pile body bears the pressure of building load. The force is transmitted from the top of the pile to the bottom of the pile, and the force of the pile body changes with the change of building load; while anti-floating pile is pull-out pile body that bears tensile force. The force of ordinary anti-floating pile is also transmitted from the top of the pile to the bottom of the pile, and the force of the pile body changes with the change of groundwater level, but the force mechanism of the two is just opposite. Anti-floating anchor is to drill holes in the foundation rock by down-the-hole drilling rig, and connect the foundation of structure or construction with the foundation rock layer as a whole by setting anti-floating anchor as part of the foundation or superstructure, so that the foundation can effectively resist the buoyancy of groundwater.

[0003] The existing patent (publication number: CN217651776U) discloses an anti-floating anchor rod, including a high-pressure grouting body and an anchor plate, wherein the high-pressure grouting body is connected to the anchor plate, a plurality of anchor bars are arranged inside the high-pressure grouting body, and the plurality of anchor bars are connected to the anchor plate, and a grouting pipe is also arranged inside the high-pressure grouting body.

[0004] The above-mentioned comparative document points out that the anchor rod diameter of the utility model can be greatly increased under the premise of using less grouting material, and according to the actual use verification, the anti-buoyancy of the anchor rod can be greatly increased, which greatly increases the anti-buoyancy; the high-pressure grouting body in the anchor rod structure is transformed from a tensile state to a compressive state, and no cracks will be generated; when the anchor rod structure does not use prestress, groundwater will not enter the rod body, thereby avoiding corrosion of the internal anchor bars. However, since the anchor rod length and depth of the device are fixed, once the design and installation are completed, it is difficult to make on-site adjustments. Such a design may limit the device in some occasions where the groundwater level changes greatly or in application scenarios that require dynamic adjustment according to actual conditions. Different geological conditions may have different requirements for the length and depth of the anchor rod. For example, between soft soil layers and hard rock layers, anchor rods of different lengths may be required to achieve the best anti-buoyancy effect. The fixed length design may limit this adaptability. Utility Model Content
