Stay cable lower anchor head dehumidification structure
The invention discloses a stay cable lower anchor head dehumidification structure. The stay cable lower anchor head dehumidification structure comprises a fixed end anchorage device, an anchor bearingplate and a plurality of steel strands, the plurality of steel strands are arranged on the fixed end anchorage device; the fixed end anchorage device is positioned in the anchor bearing plate; one end of a cable conduit is hermetically connected with the anchor bearing plate; the other end is internally sealed through a sealing piece; the fixed end anchorage device and the steel strands are partially accommodated in a cable guide pipe; the steel strands penetrate through the sealing piece and extend out of the cable guide pipe; and an air pipe structure is pre-buried in the fixed end anchorage device and inputs dry air into the cable guide pipe. The dry air and original air in the cable guide pipe are mixed to flow; then, the air returns to the inner cavity of the outer protective cover from the pre-buried air pipe structure and a gap between the fixed end anchorage device and the cable guide pipe; by means of the design, the dry air enters from the air inlet of a lower anchor head and then is exhausted from the exhaust hole of the lower anchor head, the path through which the air passes is short, energy loss is relatively small, and the requirement for air supply equipment is low.
本发明公开了一种斜拉索下锚头除湿结构，包括固定端锚具、锚垫板及若干钢绞线，若干钢绞线安装于固定端锚具，固定端锚具位于锚垫板内，索导管一端与锚垫板密封连接，另一端通过密封件实现内部密封，固定端锚具及钢绞线部分收容于索导管，钢绞线穿过密封件从索导管伸出，风管结构预埋于固定端锚具并向索导管内输入干燥空气，干燥空气与索导管内原有空气混合流动，然后从预埋的风管结构和固定端锚具与索导管之间的间隙回到外保护罩内腔，降低内环境湿度，从而对固定端锚具和钢绞线裸露部分进行防腐保护，通过上述设计，干空气从下锚头进气口进入然后从下锚头排气孔排出，气体所经过的路程较短，能量损失相对较少，对送风设备的要求较低。
