Cable-stayed bridge beam end cable guide pipe adjusting and positioning device and construction method
The invention discloses a cable-stayed bridge end cable guide pipe adjusting and positioning device, a stay cable is arranged in a cable guide pipe in a penetrating mode, one end of the stay cable is arranged on a C-shaped head of a front fulcrum hanging basket through a tensioning rod and a tensioning assembly, and the adjusting and positioning device comprises a positioning assembly and an adjusting assembly arranged on a suspended pouring support. The suspended pouring support is welded and fixed to the front end of the front fulcrum hanging basket, an anchor bearing plate is arranged at the lower end of the cable guide pipe, and the positioning assembly is arranged below the anchor bearing plate and supported by a bottom basket of the front fulcrum hanging basket. Meanwhile, the invention further discloses a construction method for adjusting and positioning the cable-stayed bridge end cable guide pipe. According to the adjustment assembly, the design offset distance, the mileage and the elevation of the observation point of the cable conduit are independently adjusted, so that the adjustment amplitude is controllable, and meanwhile, the adjustment efficiency of the beam end cable conduit is improved; the adjusting assembly and the positioning assembly are relatively independent, the part, invading the concrete main beam body structure, of the adjusting and positioning device is reduced, and therefore construction interference of the concrete main beam body structure of the adjusting and positioning device is reduced.
本发明公开了一种斜拉桥梁端索导管调校定位装置，所述索导管内穿设有斜拉索，所述斜拉索的一端通过张拉杆和张拉组件设置在前支点挂篮的“C”形头上，所述调校定位装置包括定位组件和设置在悬浇支架上的调校组件，所述悬浇支架焊接固定在前支点挂篮前端，所述索导管的下端设置有锚垫板，所述定位组件设置在锚垫板下方且被前支点挂篮底篮支撑；同时还公开了一种斜拉桥梁端索导管调校定位的施工方法。本申请的调校组件针对索导管观测点的设计偏距、里程和高程单独调校，使得调校幅度可控，同时提高了梁端索导管的调校效率；调校组件与定位组件相对独立，减少调校定位装置侵入混凝土主梁主体结构的部分，从而降低调校定位装置混凝土主梁主体结构施工干扰。
