Well-sweep, member most key arched more bridge pole one
of,,, adaptability concern bridge the security and use
durability normallies of structure its dependability.
OVM construct and offer one a kind of new research and
well-sweep that improves mosts , pole's guy cable anchor
solid department and technological solutionses to engineering
design by company, In order to solving for many years
domestic.
Hanger
rod, tie rod is arched bridge most valve key of one of
the structural member, its dependable, freeze thaw durability,
adaptability relate to to bridge structure of safety and
normal praxis.
OVM syndicate direction engineering design and construction
tender a kind latest research and betterment of hanger
rod, tie rod back stay anchor solid body system and technique
solution, with settle polypeptide in the last years concerning
said system amid of many subject.
...........................................................................................
OVM basic schemes and propose, OVM's the new achievements
in research mosts of company who company offer, Its outstanding
characteristic is:
1)It is safe, reliable to offer one, resist tired performance
and antiseptic performance well, Easy OVMLZM well-sweep
system and reliable constructing OVMXG steel that help
entangle department of line pole system that constructs.
2)Most new well-sweep system adopt new-type PES( FD) low
all antiseptic to ask for body, new-type waterproof structureses
and lean towards ball that put entangle device multiple
new technology, new structures stresseses, Solve and ask
for short times fracture, underpart enter sheath and short
well-sweeps meet out of shape problem water HDPE body
from whole, Improve the security and durability of the
well-sweep effectively.
3)Newest its short well-sweep scheme of system of well-sweep
can adapt to tying vertical displacement in the bridge
floor , Reduce short well-sweeps because bridge floor
vertical additional strengths raise the security of the
structure.
4)Solid departments that one a kind of most new-type steels
entangle department of line pole system department of
OVMXG pole anchor, it adopt antiseptic structures all
and prevent and ask for body new technology who stress
fracture, Form a complete set the careless system of anchor
with high reliable anchor careless performance under the
low stress state. However, at traditional parallel department
of steel wire poles easy installations have good antiseptic
performances department of OVMXG pole anchor solid departments.
According to the reality of the project, Liuzhou OVM company
can also be according to the needs of actual project,
Carry on the special well-sweep, designed and form a complete
set by the pole system.
For guaranteeing the safe handling and benefit daily maintainings
of bridge, OVM use OVM technology and at company of OVM
installation to complete set by company( or be guided
and be installed) well-sweep, it offer well-sweep of it
is pole systematic maintaining and cured and propose.
OVM
syndicate tender of basic scheme and submittal, is OVM
syndicate of latest research fruit, its sailing over of
characteristics is:
1) tender a kind safety, firm, have good antienzyme fatigue
performance sum rot proof performance, easy to construction
of OVMLZM hanger rod system sum firm, construction amenity
of OVMXG steel stranded wire tie rod system.
2) latest of hanger rod system adoption new model PES(
FD) low stress whole rot proof cord corpus , new model
flood control structure sum can be partial to pendulum
of ball lay apparatus iso - several new techniques, new
structure, from the intake workinteger settle cord corpus
HDPE jacket short time shake, down terminal inflexion
sum short hanger rod adaptation strain of subject, availably
stilted hanger rod of safety and freeze thaw durability.
3) latest of hanger rod system its short hanger rod scheme
able adaptation let up short hanger rod because of bridge
face longitudinal direction displacement generate of addition
towing force because of bridge face system longitudinal
direction displacement, from, stilted structure of safety.
4) OVMXG tie rod anchor solid body system is a kind latest
model steel stranded wire tie rod system, its adoption
whole rot proof structure and keep cord from corpus stress
shake of new techniques, amalgamation kit have under lowly
the stress the status higher - firm anchor 固 performance
of anchor 固 system.Thereupon, OVMXG tie rod anchor solid
body system ratio tradition of parallel expanded metal
lathing tie rod more easy installation sum have better
rot proof performance.
According to engineering of physical truth, 柳 state OVM
syndicate may also with according to practice engineering
of requirement, steer special hanger rod, tie rod system
design and kit.
For ensuring bridge of safety praxis sum easy to day -
to - day of maintenance, OVM syndicate will vs complete
set praxis OVM technique amalgamation from OVM syndicate
installation( or instruct installation) of hanger rod,
tie rod system tender hanger rod, tie rod system of maintenance
sum curing submittal.
