Prestressed anchoring structure for reinforcing side slope retaining wall and construction method of prestressed anchoring structure
The invention belongs to the technical field of retaining wall supporting structures, and particularly relates to an anchoring structure for reinforcing a side slope retaining wall, which comprises a plurality of anchor rods arranged at intervals, and each anchor rod comprises a plurality of sections of rod bodies with external threads; the anchor rod is provided with an anchoring section and a free section capable of axially stretching after being prestressed, a drill bit is arranged at one end of the anchoring section, and the other end of the anchoring section is connected to the free section. A slurry outlet hole is formed in the drill bit; the length of the free section is set to at least penetrate through the slip crack surface, and the periphery of the free section is sleeved with a heat-shrinkable sleeve; a gap is formed between the heat-shrinkable sleeve and the outer wall of the free section, and a lubricant is arranged in the gap; the end, close to the anchoring section, of the heat-shrinkable sleeve is connected to the junction of the free section and the anchoring section in a sealed mode. A latticed column made of concrete is arranged on the foundation of the side slope retaining wall, and the free section of the anchor rod penetrates through the slip crack face and is connected to the latticed column. Therefore, the problems that an existing slope retaining wall reinforcing structure is limited in application range, and the reinforcing effect is difficult to guarantee are solved.
本发明属于挡土墙支护结构技术领域，具体涉及一种边坡挡土墙加固用锚固结构，包括多根间隔设置的锚杆，锚杆包括多段具有外螺纹的杆体；锚杆具有锚固段和在受预应力后能够轴向拉长的自由段，锚固段的一端设有钻头，另一端连接于自由段；钻头上设有出浆孔；自由段的长度设置为至少穿过滑裂面，且自由段的外周套设有热缩套管；热缩套管与自由段的外壁之间设有间隙，且间隙中设有润滑剂；热缩套管靠近锚固段的一端密封地连接于自由段和锚固段的交界处；边坡挡土墙的基础上设有由混凝土制成的格构柱，锚杆的自由段穿过滑裂面并连接于格构柱。由此，解决了当前对边坡挡土墙的加固结构适用范围有限、且难以保证加固效果的问题。
