The invention discloses a tensioning and locking structure of a pre-stressed anchor cable and a construction method. Two groups of anchor cables with different free section lengths are arranged in one anchoring body; the anchor cables with the same free section length in two adjacent anchoring bodies are locked on the same anchorage device; the anchor cable is locked on a enclosure pile wall from the two sides through a wedge-shaped base plate and the anchorage device, and a waist beam is not arranged; the cable body arranged in one anchoring body is a pressure stress dispersion type anchor cable or a tensile stress dispersion type anchor cable; the anchoring body is a solidified soil body or a cement mortar body; the diameter of the anchoring body is larger than 120 mm and smaller than 1200 mm. The enclosure pile wall is of a pile wall structure formed by connecting enclosure row piles and top beams, or is of an underground diaphragm wall structure. The tensioning and locking structure has the advantages that deformation is effectively controlled, safe and reliable social benefits are achieved, meanwhile, the manufacturing cost of foundation pit supporting engineering can be reduced, and high economic value is achieved.
本发明公开了一种预应力锚索的张拉锁定结构与施工方法，所述的一根锚固体内设置二组不同自由段长度的锚索；相邻二根锚固体内相同自由段长度的锚索锁定在同一个锚具上；锚索从两侧通过楔形垫板和锚具锁定在围护桩墙上，不设腰梁；一根锚固体内设置的索体是压应力分散型锚索或拉应力分散型锚索；锚固体是固化土体或水泥砂浆体；锚固体的直径大于120mm，小于1200mm；围护桩墙是由围护排桩并设置冠梁连接成桩墙结构，或者为地下连续墙结构。该专利具有效控制变形和安全可靠的社会效益，同时能降低基坑支护工程的造价，具有较高的经济价值。
