Prestressed anchor cable tensioning bearing structure and construction method
The invention discloses a pre-stressed anchor cable tensioning bearing structure and a construction method. The pre-stressed anchor cable tensioning bearing structure comprises an anchor cable pile with an anchor cable body, a pressure-bearing stress steel body, an anchor head bearing body and a tensioning locking anchorage device. The anchor cable pile is fixedly embedded in a soil layer, and the anchor cable body to be tensioned upwards extends out of the base surface. The pressure-bearing and stress-bearing steel body is supported on the base surface, the lower end of the pressure-bearing and stress-bearing steel body extends into a soil layer to form a whole with the anchor cable pile, and the pressure-bearing and stress-bearing steel body and a cushion concrete layer poured on the base surface subsequently form a whole. The anchor head bearing body is arranged on the cushion layer concrete layer in a supported mode, the anchor cable body penetrates through the anchor head bearing body in the axial direction, then is tensioned and is tensioned and locked to the anchor head bearing body through the tensioning locking anchorage device, and the lower end of the anchor head bearing body and a waterproof protection concrete layer poured on the cushion layer concrete layer subsequently form a whole. According to the structure, drilling on the main body foundation structure is effectively avoided, and the anchor head bearing body cannot fracture the cushion layer concrete layer to affect the tensioning effect and the cushion layer structure when the anchor cable body is tensioned.
本发明公开了一种预应力锚索张拉承载结构及施工方法，包括：带锚索体的锚索桩、承压受力钢体、锚头承载体及张拉锁定锚具。锚索桩嵌固于土层中，待张拉的锚索体向上伸出基底面。承压受力钢体支撑于基底面上，且下端伸入土层内与锚索桩形成整体，并承压受力钢体还与后续浇筑于基底面上的垫层混凝土层形成整体。锚头承载体支设于垫层混凝土层上，锚索体沿轴向穿设锚头承载体后张拉并通过张拉锁定锚具张紧锁定于锚头承载体上，锚头承载体的下端还与后续浇筑于垫层混凝土层上的防水保护混凝土层形成整体。本发明结构，有效避免在主体基础结构上进行钻孔，并锚索体张拉时的锚头承载体不会将垫层混凝土层压裂而影响张拉效果以及垫层结构。
