Advantage
1----Anti-theft: cover and base frame integrate connection, hinge-type opening, sledgehammer hit not break it, completely anti-theft.
2----Load-bearing great: the toughness of ductile iron is fourfold that of ordinary cast iron, close to steel materials, suitable for all kinds of road use!
3----Corrosion resistent: Sewer internal environment complex, filled with various chemical substances, ductile iron does not suffer chemical corrosion, service life more than 30 years.
4---- Opens conveniently: light weight, single unarmed can be open, convenient downhole maintenance!
5----Superior safety performance: It often occurred underground explosion accident, fly up covers scarred passers-by ,
manhole covers integration connections will not depart from the ground.
And
1.Environmental protection:
With raw material non-toxicity, it will not influence to user.
2.Applications:
(1) Electric power pipeline well; post; telecommunication; communication pipeline well;
(2) Street lamp well; fire control well; all kinds of valve wells;
(3) City water; drainage pipeline well; heat supplied; gas well;
(4) Open ditch; it as well as can be made according to customers requirements.
3. Anti-theft:
Non-recycle, anti-theft naturally, the lock attachment can prevent tunnel products from losing, therefor city blackhole can be stopped totally.
