Suspension bridge anchorage structure with anchor body embedded with diaphragm wall foundation and construction method
The suspension bridge anchorage structure comprises an underground diaphragm wall, a bottom plate, the anchor body, a cable and an anchoring system, a top beam is arranged at the top of the underground diaphragm wall, and the anchor body is arranged in the underground diaphragm wall; the bottom plate is step-shaped, is arranged in the middle of the diaphragm wall, and is in direct contact with an external soil body; the front side of the anchor body is provided with a front anchor chamber, the rear side of the anchor body is provided with a rear anchor chamber, the front end of the front anchor chamber is provided with a splay cable clamp, the rear anchor chamber is internally provided with a cable anchoring system, a cable is obliquely arranged in the diaphragm wall, and the cable penetrates through the anchor body after being dispersed by the splay cable clamp. According to the suspension bridge anchorage structure with the anchor body embedded with the foundation, the cable force of the cable acts on the position below the center of gravity of the anchorage through downward movement of the anchor body, the anchorage has the anticlockwise rotation trend, the step-shaped bottom plate is matched, the resistance effect of surrounding soil can be fully exerted, the stress characteristic of the anchorage can be remarkably improved, the size of the anchorage can be greatly reduced, and the service life of the anchorage is prolonged. Building materials are saved, the construction period is shortened, and energy conservation and environmental protection are achieved.
本发明公开了一种锚体与基础相嵌合的悬索桥锚碇结构，包括地连墙、底板、锚体、缆索及锚固系统，地连墙顶部设有冠梁，锚体设于地连墙内部；底板为台阶型，底板设置于地连墙中部，底板与外部土体直接接触；锚体前侧设有前锚室，后侧设有后锚室，前锚室前端设有散索夹，后锚室内设有缆索锚固系统，缆索斜置于地连墙内部，缆索经散索夹分散后，贯穿锚体。本发明锚体与基础相嵌合的悬索桥锚碇结构，通过锚体下移使得缆索缆力作用于锚碇重心下方，锚碇具有逆时针转动趋势，配合台阶型底板，可充分发挥周边土体抗力作用，显著改善锚碇的受力特性，可大幅减小锚碇尺寸，节约建筑材料和施工工期，更加节能环保。
