Specific embodiment
Referring to Fig. 1-2, the utility model relates to a kind of dehumidifying of dry air stayed structure, it includes air inlet pipe 1 and goes out
Tracheae 4.
The air inlet pipe 1 is filled in upper anchorage is arranged gas outlet 2 at anchor face 5, and 1 air outlet 3 of air inlet pipe is close under cable body
Anchorage fills 5 position of anchor face, i.e. the top setting gas outlet 2 of air inlet pipe 1 is to dry Cable using 1 part dry air of air inlet pipe
Body top, and the dry air of air inlet pipe air outlet 3 then dries the part cable body close to lower anchorage position.
The escape pipe 4 and air inlet pipe 1 be not in cable body on same steel wire axis.
In said structure, cable body is made of 84 steel wires, is substituted cable body steel wire using 2 ~ 25 air inlet pipe 1 and is distributed in
The cable body cross section region Shang Ge；Preferably, 1 quantity of air inlet pipe is 2；It can be by cable body cross section week according to cable body specification and length
Region quantity is divided on direction is not less than 1；Preferably, 2 regions up and down are divided into the circumferential direction of cable body cross section；According to rope
