Problems solved by technology

[0002] For the demolition of the cross-line suspender arch bridge, the existing demolition methods (blasting demolition, mechanical chisel removal, beam body block cutting and hoisting demolition, etc.) not only take up a long construction time on the road (generally, the traffic time of each cross-line bridge is closed for 10 to 36 hours ), high safety risks, and will generate a large amount of dust, solid waste, vibration and noise pollution. Secondary crushing and waste transportation also require a large amount of equipment, consuming a large amount of oil, manpower and other resources

Abstract

The invention discloses an overall carrying dismantling method for an overline suspender arch bridge, which comprises the following steps of: firstly selecting a beam storage site with a proper size, reinforcing a suspender arch bridge, cutting a side span, performing hoisting and dismantling, then closing main line traffic under the bridge, carrying a support frame adaptive to the beam bottom clearance height by a vehicle set to run to the beam bottom, pre-jacking the suspender arch bridge by the vehicle set, and after the arch ring is cut, rapidly moving the whole suspender arch bridge out of the main road to the beam storage site to be broken and chiseled away. The method has the technical effect of quickly dismantling the overline suspender arch bridge, is small in traffic influence, low in construction risk, environmentally friendly, good in application prospect and capable of being widely applied to the technical field of bridge dismantling.

Description

technical field [0001] The invention relates to the technical field of bridge demolition. More specifically, the present invention relates to a method for dismantling the overall piggyback of a line-span suspender arch bridge. Background technique [0002] For the demolition of the cross-line suspender arch bridge, the existing demolition methods (blasting demolition, mechanical chisel removal, beam body block cutting and hoisting demolition, etc.) not only take up a long construction time on the road (generally, the traffic time of each cross-line bridge is closed for 10 to 36 hours ), high safety risks, and will generate a large amount of dust, solid waste, vibration and noise pollution. Secondary crushing and waste transportation also require a large amount of equipment, consuming a large amount of oil, manpower and other resources. [0003] How to quickly dismantle the cross-line suspension rod arch bridge and reduce the traffic impact caused by construction is a techni...
