The noise barrier
project consists of 4 pieces located in the city of Hong Kong along the streets of Tai Po Tai Wo Road e Gascoigne road.
A cantilevered
barrier of 170 metres long and 6 metres height, a vertical barrier of 140
metres long and a variable wide from 23 to 20 metres, a vertical barrier 70
metres long and 4,5 metres height and a semi-full-cantilivered noise barrier of
500 metres long and 6 metres height. The
space frame structure of the noise barrier has been constructed from hot-dip
galvanized 50 mm tubes for the main structure and 30 mm tubes for the secondary
structure. The entire structure is covered with translucent polycarbonate
panels, with a different range of apertures, each one with a dimensions of 3 m
x 0.65m. The panels change color with the daylight and react to the impulse of
the shaft located at the intersection of every panel. During the day, the new
noise barriers forms an harmonious unity with the surrounding landscape. They also integrate an innovative green system. The design is developed
incorporating the natural growth characteristics of the grass. What makes the
design unique is that the construction itself, as a sound barrier is a living,
green unit. Light and shadow on the white panels
establish a suggestive relationship with the surrounding landscape. After sunset, the
artificial light illuminates the architectural body from inside, turning the
shapes into a illuminated sculptures.
HIGH TECH BLADE RICCIO
The focal point of
the whole system is the blade named RICCIO
It?s an innovative technological system that transform the air movement in energy and
then, thanks to a generator, in electricity. The blade dimensions are: a
= 1 cm; b = 1 cm; l = 40 cm; Weight = 150gr
During the vehicle
transit close by the noise barrier it produces a pressure wave with a kinetic
energy and potential. This energy is transferred to the blade orthogonally to
the wave front. Then the blade stimulated by the wave, begin swinging in
analogy to a damped harmonic oscillator.
Considering the
kinetic energy E = *m*?2A2 = *m*K/m*A2 =
*(a*b3)/(4h3)*?*A2, the blade
dimensions (a, b, l), the material (?) and
the extent of the first oscillation, the energy produced by the blade(per second) is: E ? 1 Joule or W
? 1 Watt.
The electricity produced will be stored by appropriate capacitors. The
electricity will be used to manage the noise barriers and to provide clean
energy for the districts.
