Abstract

A multi-layer spiral blade self-drilling soil bolt and its construction method, comprising a front-end bolt body (1), and a front-end helical blade (4) is provided on the outer surface of the front-end bolt body (1) near the drill tip ‑1), a grout hole (5) is opened on the side wall of the front end anchor body (1) and near the front helical blade (4‑1), and the other end of the front end anchor body (1) passes through the threaded connection part ( 6) Connect with one end of the middle anchor rod body (2), the other end of the middle anchor rod body (2) is connected with one end of the extended anchor rod (8) through the connecting sleeve (7), the middle anchor rod body (2) Helical blades (4-2) are arranged on the outer surface of the invention. The structure of the invention is reasonable, and the blades have strong penetrating power in soft soil areas. The construction technology is safe and reliable, the contact area is increased, the anchoring force is enhanced, and the Improve the construction efficiency and construction quality, and ensure that it can more effectively improve the pullout resistance of the anchor rod in different soil layers.

Description

technical field [0001] The invention relates to an anchor rod and a construction method thereof, in particular to a multi-layer spiral blade self-drilling soil anchor rod and a construction method thereof, belonging to the technical field of drilling and anchoring. Background technique [0002] For buildings or structures buried in the basements of buildings with high groundwater levels, such as subways, underground shopping malls, civil air defense fortifications, large pools, and wave-dispelling pools at the bottom of dams, they must not only bear the weight of the structure, but also bear the impact caused by the high groundwater level. buoyancy on the bottom of the pit. When the buoyancy force is large enough to overcome the weight of the structure, floating, tilting or damage will occur, so the harmful vertical displacement caused by buoyancy must be effectively controlled in the structural design. [0003] At present, the anti-floating design is widely used in enginee...
