The connector includes the pvc pipe at right angles arranged, the pvc pipe right angle has water outlet, the pvc pipe End is equipped with to silk.
Described extremely frigid zones downlead cable infiltration anti-freezing device has opening, the steel on the big steel ring There is the groove with the aperture position face of the big steel ring on silk screen.
The extremely frigid zones downlead cable infiltration anti-freezing device, the area of the water outlet is 2-3cm2
The extremely frigid zones downlead cable infiltration anti-freezing device, a diameter of 50-60cm of the big steel ring.
The extremely frigid zones downlead cable infiltration anti-freezing device, a diameter of 20-30cm of the drum rim.
The extremely frigid zones downlead cable infiltration anti-freezing device, between the big steel ring and the drum rim Vertical range is 40-50cm.
The extremely frigid zones downlead cable infiltration anti-freezing device, the length of the groove is 20cm.
A kind of construction method of extremely frigid zones downlead cable infiltration anti-freezing device, this method comprises the following steps:The dress It puts at gate framework, draw the zinc-plated sheath steel pipe of lower optical cable and introduces installs connector between the PVC sheath pipe of underground, and in water outlet The hole of a 50-60 ㎝ depth is dug in the lower section of mouth, and the seepage controllor of the present apparatus is put into hole, the pvc pipe right end of connector is placed on In the groove of seepage controllor, coarse sand and cobblestone are filled out in the inside, and so zinc-plated casing top of optical cable is seep water when in summer, water The outside of pvc pipe is just flowed to by water outlet, is seeped into underground.
Advantageous effect:
1. above the zinc-plated casing of the optical cable of the present invention when seeping water in summer, water just flows to the outside of pvc pipe, is seeped into underground, So as to play the effect of not ponding, prevent freezed in winter, prevent broken cable.
The present invention sets water outlet, and the area of water outlet is 2-3cm2, the water of infiltration can all be flowed out, prevented simultaneously Freezed in winter causes water outlet to block.
The configuration of the present invention is simple, it is economical and practical, it is easy to accomplish, protection can be played the role of to cable.
Groove on the steel wire that present invention is set is set, opening is set on big steel ring, pvc pipe can be risen when mounted It is easy for installation to the effect of fixed positioning.
