Modular concrete sliding mode paver with a width of 16 meters, used
for smooth and compact paving of tunnels
The truss-type bridge paver has extensive and significant
applications in the tunnel field, as shown specifically below:
Tunnel lining construction: It provides an efficient paving method
for the concrete lining of the tunnel inner wall, ensuring the
uniformity and stability of the lining, and improving the support
effect and waterproof performance of the tunnel.
Tunnel invert arch construction: It is used for the concrete paving
of the invert arch at the bottom of the tunnel to quickly form a
solid foundation structure and ensure the overall stability of the
tunnel.
In conclusion, with its characteristics of high efficiency,
accuracy, and adaptability to complex working conditions, the
truss-type bridge paver plays an important role in the construction
of the bridge and tunnel field, effectively promoting the smooth
progress and quality improvement of the project.
Features
(1) The modular assembly mode of the whole machine truss adopts a
split composite connection for the roller shaft, which is easy to
install and can expand the combination to different widths, making
it suitable for the use of bridge decks with different widths and
improving equipment utilization.
(2) This equipment uses a tire walking mechanism to directly walk
on the steel mesh of the bridge deck. If there are local
unevenness, the hydraulic cylinder is controlled by a
high-precision digital leveling instrument to adjust the elevation.
In the case where the guardrail has already been laid, suspended
structures can be used on both sides to support walking on the
guardrail;
(3) Two vibrating rollers with leveling and slurry lifting
functions, and the height and inclination angle of the rollers can
be adjusted up and down. At the same time, the shock-absorbing pad
handwheel can be adjusted arbitrarily to achieve the adjustment of
the transverse slope of the bridge deck.
(4) Equipped with a flushing system for easy daily maintenance.
(5)Provide lighting fixtures to address lighting issues during
nighttime and tunnel construction.
(6) The whole machine adopts high-frequency vibration pushing plate
to push the material, which can keep the concrete in a light and
flowing state, and the material level is uniform and consistent..
(7) Efficient compaction design effectively ensures the compactness
of concrete, and can also achieve certain ideal compaction and
leveling effects for low slump concrete.
(8) Using large-diameter high-speed rollers, it has a long wear
resistance life, flat transverse end faces, and good linear and
slurry lifting effects.
(9) High horsepower output easily maintains a high-speed and stable
paving state, which is conducive to ensuring construction quality
and improving construction efficiency.
