Description
Technical field
The present invention relates to bridge-collision-avoidance wall construction technique fields, and in particular to a kind of bridge-collision-avoidance wall Safety operation platform.
Background technology
Nowadays, urban congestion phenomenon is more and more prominent, to alleviate urban traffic pressure, ensures that citizen go on a journey safely, overhead
Bridge comes into being.Accident occurs for vehicle derailing road in order to prevent, and bridge both sides need that anti-collision wall is arranged.Anti-collision wall is bridge
Pith, as the safety guarantee structure of bridge both sides, most of anti-collision walls use reinforced concrete earth forming, belong to permanent
Property structure.The work progress of anti-collision wall is complicated, needs first to install external mold steel plate, internal model steel plate and bed die steel plate, to make external mold
Steel plate, internal model steel plate and bed die steel plate form a die cavity, and then the packing material in the die cavity, finally disassembles external mold steel again
Plate, internal model steel plate and bed die steel plate.Anti-collision wall construction difficulty is larger, especially when anti-collision wall lateral surface dismantles external mold steel plate, needs
The external mold steel plate transport disassembled to be got off by crane, but often construction site is limited in science of bridge building, field of constructing
Nearby wagon flow and stream of people's dealing are frequent on ground, and it is difficult normal operation to make big machinery.And if bridge floor is higher from the ground or in water
On face, crane operation receives the limitation of bigger, and construction is extremely difficult.
