In recent years, the rapid development
of highway, railway, urban light rail and subway etc,
has brought great conveniences to people's traveling,
but at the same time noise pollutions caused by the advanced
transportation has become a prominent social problem.
So the sound barriers have become the most effective and
feasible solution to this problem. The sound barrier is
a kind of facility to be installed between the sound source
and the recipient of sound to significantly weaken the
transmission of the sound wave, which can effectively
reduce the impact of the sound on the areas of the sound
recipients. This facility is thus called sound barrier.
Sound barriers are mainly applied for noise reduction
and insulation in the civil transportation systems including
express highway, elevated highway, urban light rail, subway
and railway etc; it may also be used to reduce the noises
in enterprise which have stricter requirement for noises
or in places where large-size cooling equipments are running.
The sound barrier is mainly composed of foundation,column
and barrier plate. The foundation is the structure to
support the load of the sound barrier, which may be separately
designed or designed to be fixed on the auxiliary structures
of the road during the road design (such as shockproof
wall and Based on the Sound Barrier bearing capacity of
the main structure, it can also be designed in separate
road design, road design together with ancillary facilities
(such as anti-wall and hard road shoulder); the column
is the main component subject to the load of the barrier;
the bottom flange of the column shall be firmly connected
with the foundation through embedded bolts, steel bars
and welding to meet the requirement for the strength of
the whole sound barrier; the sound barrier vertical plates
are the most important parts for noise reduction by sound
barrier; the barrier plates may be fixed in the column
by special high-strength springs, bolts, and angle bars
to form the sound barrier. The design, type and materials
of the sound barrier plate will have the direct effect
on the sound insulation efficiency, appearance, service
life, anti-corrosive performance, safety and reliability
of the whole sound barrier.
The research, design, manufacturing and installation of
the sound barriers of our company have taken full account
of design issues of the sound barrier under particular
requirements including the wind load along the elevated
road, express highway, urban light rail, inter-city rail,subway
and railway, crashes of the vehicles, all-weather outdoor
corrosion resistance, acid resistance and alkali resistance
etc. Featuring exquisite and beautiful shape, fine fabrication
process, easy transportation and installation,low cost
and long service life, the product is particularly suitable
for reduction of noises in railways, highways, urban transport,
urban light rail and subway etc, which is the best and
ideal facility for noise reduction in the modern cities
and highways; the product also is the beautiful scenery
in the cities.
The sound barriers designed and produced by our company
cover almost all types of products in the sound barrier
industry with full range of verities. The heights of the
sound barriers are normally between 1m - 10m with various
types and sizes, which may be fabricated and processed
based on the requirement of customers. The average noise
reduction efficiency in the area that the sound barrier
can have effect may reach 10-15dB (A) (63HZ - 4000HZ,
1/3 octave) and the maximum reduction of noise may reach
up to 25dB (A) or more. |
