Description
Technical Field
The invention relates to an anchor rod, in particular to a lead hole implanted anti-floating rock anchor rod with a supporting disc and a construction method.
Background
In order to fully develop and utilize the underground space, functions of adopting an underground structure as a garage and the like are gradually increased. The square type building is large in building area, deep in foundation burial, relatively few in building layer number, and when the underground water level is high, the self weight of the structure is not enough to resist the buoyancy of underground water, so that the basement bottom plate is bulged and damaged, the beam column joint is cracked, the bottom plate is damaged and the like.
The general structure itself has several types of anti-floating measures: a counterweight method, an anti-floating pile and an anti-floating anchor rod. The counterweight method is to increase the self-weight of the structure and balance the buoyancy of underground water by increasing the thickness of the structure or increasing the weight in the interior, but the method increases the requirement on the bearing capacity of the foundation and is mostly uneconomical; the uplift pile is mainly stressed by the friction force between a pile body and a soil layer, the penetration depth of the pile body needs to be increased in order to improve the anti-floating performance of the uplift pile, the engineering quantity is increased, the cost is increased, and the pile body driving difficulty is higher if the bottom of the structure is mainly rock mass; the traditional anti-floating anchor rod is similar to the anti-floating pile principle, the impact of the driving depth on the anti-floating capacity is large, the construction period is long, and the construction progress of the whole project is affected. Compared with other anti-floating measures, the anti-floating anchor rod has the effect of balancing the buoyancy of underground water, can also play a role in reinforcing a foundation, and cannot cause integral anti-floating failure due to the damage of a small number of anchor rods, so that the anti-floating anchor rod is widely applied to engineering practice.
In conclusion, the anti-buoyancy force of the anchor rod is provided by the side friction force of the anchor rod, the side friction force is in direct proportion to the anchoring length of the anchor rod, but the overlong anchor rod causes material waste and increases the construction workload; because it is applied to the place with groundwater, under the effect of groundwater, the slip casting of long stock is difficult, and its slip casting quality is difficult to guarantee. In view of the above, it is desirable to provide a rock bolt with increased frictional resistance between the bolt and the anchoring body and the surrounding rock and soil mass.
