Description

River course bank protection reinforced structure of adoption stock anchor integration Technical Field The invention relates to the technical field of slope reinforcement, in particular to a river slope protection reinforcement structure adopting anchor rods for anchoring integration. Background In river course treatment engineering, loose soil (such as silty clay, loose sand layer) side slope is because of shear strength is low, and structural stability is poor, and flood season is easily received rivers to wash and is initiated to slide, collapses, need to consolidate the promotion side slope bearing capacity through the stock. The current anchor rod reinforcement technology of the river slope in the soft soil generally adopts a step-by-step operation mode of drilling, hole cleaning, manual rod feeding and pressure grouting, and has a plurality of technical bottlenecks which are difficult to break through. Firstly, the hole wall lacks sufficient supporting force after the soft soil is drilled, collapse is easy to occur when the hole is cleared and the rod is conveyed, so that the anchor rod cannot be smoothly conveyed to a preset depth, even the anchor rod needs to be drilled again, the construction cost and the construction period are greatly increased, the hole wall is easily blocked by slurry although the slurry is used for protecting the wall in part of engineering, the slurry is difficult to be fully combined with the soil body during subsequent grouting, and the anchoring effect is weakened. Secondly, traditional stock mostly is smooth body of rod or simple screw structure, relies on grout and the cohesive force of soil body to realize the anchor after the grout, and the loose soil porosity is high, the soil body cementation nature is poor, and the grout easily runs off to peripheral soil body, forms local cavity, leads to stock and soil body seaming force not enough, and the resistance to plucking is often less than 150kN of design requirement, can't satisfy the long-term stable demand of side slope. Meanwhile, each working procedure of drilling, delivering the rod and grouting is disjointed, and cooperative operation cannot be formed, so that the efficiency is low, secondary hole wall collapse is easily caused by working procedure intervals, and the construction risk is increased.
