The invention discloses an anchor pipe type cable-girder anchoring structure of a cable-stayed bridge concrete girder, and a positioning method thereof. The cable-girder anchoring structure comprisesan anchoring assembly and a stay cable connecting assembly, wherein the anchoring assembly comprises a cable guide pipe, an anchoring base plate, a web plate, a bottom plate and a stiffening rib, thestay cable connecting assembly comprises an anchoring ring and an anchoring cup, the cable-girder anchoring structure is buried in the concrete girder web plate, and the bottom of the cable-girder anchoring structure is flush with the concrete box girder bottom plate; the cable guide pipe is locally buried in the web and the top plate; a connecting rib and a spiral rib surround the stay cable guide pipe and are buried in the concrete box girder; and the stiffening rib is used for connecting the anchor base plate and the cable guide pipe, and the stay cable is anchored on the anchor base platethrough the anchor ring and the anchor cup. The structure can adapt to different transverse inclination angles of the stay cables, and the anchor base plate and the cable guide pipe adopt a fixed angle, so the manufacturing difficulty is reduced, accurate positioning can be achieved only according to the inclination angle of the cable guide pipe of a main tower during installation, construction ofthe stay cable is convenient, batch manufacturing can be achieved, the quality is guaranteed, construction is rapid, and stress is reliable.
本发明公开了斜拉桥混凝土主梁的锚管式索梁锚固结构及其定位方法，包括锚固组件、斜拉索连接组件，其中，锚固组件包括索导管、锚垫板、腹板、底板、加劲肋，斜拉索连接组件包括锚环、锚杯，所述索梁锚固结构埋于混凝土主梁腹板中，索梁锚固底部与混凝土箱梁底板平齐；索导管局部埋于腹板和顶板中；连接筋和螺旋筋环绕在斜拉索索导管上并埋设在混凝土箱梁内；加劲肋用于连接锚垫板和索导管，斜拉索通过锚环和锚杯锚固在锚垫板上。该结构能适应各斜拉索横向倾角的不同，锚垫板与索导管采用固定角度，降低制造难度，安装时只需根据主塔索导管倾斜角就可实现精准定位，使斜拉索的施工更加方便，可批量制造，保证质量、施工快捷、受力可靠。
