Synchronous grouting structure for anchor rod and anchor disc of spiral anchor foundation
The invention discloses a spiral anchor foundation anchor rod and anchor disc simultaneous grouting structure, and belongs to the field of spiral anchors, the spiral anchor foundation anchor rod and anchor disc simultaneous grouting structure comprises a slurry storage barrel and an anchor rod, the outer wall of the anchor rod is provided with a plurality of groups of grouting holes, the outer wall of the anchor rod is fixedly connected with an anchor disc, and the anchor disc is fixedly connected with the slurry storage barrel. The upper side and the lower side of the anchor disc are fixedly connected with multiple sets of grouting pipes communicating with one another, the multiple sets of slurry supply holes communicate with the anchor disc grouting holes in the upper side and the lower side of the anchor disc correspondingly, side grouting is carried out through the grouting holes in the outer wall of the anchor rod, the compactness of soil on the side of the anchor rod is compacted, meanwhile, grouting is carried out through the slurry outlet holes in the end of the anchor rod, and the grouting efficiency is improved. The compactness of soil at the end of the anchor rod, the pile side resistance of the anchor rod and the pile end resistance of the anchor rod are improved, meanwhile, grouting is conducted through the grouting pipe on the anchor disc on the outer side of the anchor rod, the diameter of the anchor disc is larger than or equal to three times of the diameter of the anchor rod, and therefore the grouting radius is increased by three times or more through grouting on the outer side of the anchor disc, and the bearing performance of grouting on the side of the anchor rod is greatly improved.
本发明公开了一种螺旋锚基础锚杆和锚盘同时注浆结构，属于螺旋锚领域，一种螺旋锚基础锚杆和锚盘同时注浆结构，包括储浆桶和锚杆，所述锚杆外壁开设有多组注浆孔，所述锚杆外壁固定连接有锚盘，所述锚盘上下两侧固定连接有多组相互连通的注浆管，多组所述供浆孔分别与锚盘上下两侧的锚盘注浆孔相连通，通过锚杆外壁的注浆孔进行侧注浆，压实了锚杆侧土壤的密实度，同时通过锚杆端部出浆孔注浆，提高了锚杆端部土壤密实度和锚杆桩侧阻力和锚杆桩端阻力，同时通过锚杆外侧的锚盘上的注浆管进行注浆，锚盘的直径大于等于锚杆直径的3倍，因此锚盘外侧注浆使得注浆半径增大3倍及以上，大幅度提高了锚杆侧注浆的承载性能。
