Sealing anchor cable of waterproof early warning system in inhaul cable anchoring zone and manufacturing and installing method of sealing anchor cable
A sealing anchor cable of a waterproof early warning system in an inhaul cable anchoring zone comprises an inhaul cable body, an anchor, a pre-buried pipe, a protective cover and a waterproof cover, wherein the inhaul cable body is anchored on an anchor bearing plate through the anchor; the protective cover is located at the anchor end, and the waterproof cover is located at the other end of the pre-buried pipe of the inhaul cable body. A gas injection valve I is arranged on the protective cover at the anchor end, a gas injection valve II is installed at the end, far away from the anchor end, of the pre-buried pipe, and the pre-buried pipe is filled with inert gas enabling the anchor to be isolated from oxygen and moisture. An outlet of the gas injection valve I and an outlet of the gas injection valve II are both connected with a pressure early warning system composed of a pressure sensor, a data acquisition instrument, a central processor and a data transmitter. When gas pressure in the pre-buried pipe is lower than a certain pressure value, an early warning signal is provided and transmitted to bridge maintenance institutions or persons through mobile data. A pressure difference isolation device can be arranged in the pre-buried pipe of the sealing anchor cable. The sealing anchor cable can carry out corrosion-resistant protection on the anchor, can achieve monitoring early warning of waterproofness in the pre-buried pipe, and it is guaranteed that the service life of the anchor structure and the service life of a bridge body structure are the same.
