Description
Technical field
The present invention relates to the realm of building construction, it is more particularly related to a kind of continuous
Beam Demolition Construction method.
Background technology
In the engineerings such as building, bridge, aviation and pipe-line, being commonly encountered a kind of beam has
Three or more supportings, referred to as continuous beam, continuous beam has intermediate support, so its deformation
It is generally smaller than single beam with internal force, thus using very wide in engineering structure.
Continuous beam is manufactured using armored concrete mostly, is usually used in manufacturing bridge, and under-clearance
Generally higher than 4m, stabilized structure, and continuity are good, in the construction for removing continuous beam very
Difficulty, traditional Demolition Construction method can not remove continuous beam safely.
The content of the invention
Problem to be solved by this invention is to provide a kind of continuous beam Demolition Construction method.
To achieve these goals, the technical scheme taken of the present invention is：A kind of continuous beam is removed
Construction method, it is characterised in that comprise the following steps：
(1) preparation of construction：Get out remove the plant equipment and instrument of continuous beam；
(2) bridge deck is removed：Bridge deck remove include bridge floor pitch remove, expansion joint dismounting,
Anti-collision wall is removed；
(3) bearing is locked：In bearing surrounding 20mm steel plate connects bearing upper and lower cover platess, weldering
Connect firmly, lock bearing；
(4) support is set up：Continuous beam removes support system by HR100 portal supports, regulation
Bar, in length and breadth intertie, horizontal reinforcing bar, bridging, adjustable frames and bracket, wood stupefied
Distribution beam is constituted；
(5) box beam is cut：Bridge is divided into recycle after some pieces and meets tonnage demand
Loop wheel machine lifting landing, the first longitudinally cutting transverse cuts again of main line continuous beam, ring road continuous beam is direct
Transverse cuts, box beam cutting is using the cutting of electronic rope saw cut system, in units of connection, main line
The left width of bridge and the cutting of right width widened section are carried out by order horizontal behind first longitudinal direction, the right width mark of main line bridge
Quasi- section and each ramp bridge only carry out transverse cuts；
(6) beam block is removed：After the completion of box beam segmentation cutting, lifted and cut from crawler crane
Beam block lands；
(7) bridge pier is removed：Remaining bridge pier part is cut using pick machine.
It is preferred that, the bridge floor pitch in the step (2) uses LXH1300D type pitch millings
Per 150m as a milling interval on machine milling, bridge floor, discarded pitch is transported by transport vehicle
Outside the venue.
It is preferred that, at step (2) the Bridge expansion joint first with sharp weapon along seam cut open it is flexible
The rubber strip of seam, middle shaped steel is cut off with oxyacetylene metal-cutting, and remaining residual fraction is removed in the lump with end floor beam.
It is preferred that, there is one of anti-collision wall on the outside of main line bridge in the step (2), ramp bridge has
Twice anti-collision wall, anti-collision wall is hung using rope saw cutting machine stripping and slicing and removed.
It is preferred that, in the step (5) in the rope cutting process of electronic rope saw, rope fortune
Protection is blocked with security protection before dynamic direction, and safety sign is set in certain area, is forbidden
Pedestrian enters construction operation region.
Beneficial effect：The continuous beam Demolition Construction method includes：1. preparation of construction；2. bridge floor
System removes；3. bearing is locked；4. support is set up；5. box beam is cut；6. beam block is removed；
7. bridge pier is removed.Employ and first remove the bridge floor facilities such as pitch, anti-collision wall, then proping is cut
Cut box beam, last hoisting beam block and cut bridge pier, ensured construction safety and efficiency, constructed
During set professional commanding, operating personnel submit onself to someone's direction personnel's instruction construction, it is ensured that safety.
Embodiment
The following detailed description of a kind of preferred embodiment of continuous beam Demolition Construction method of the invention.
A kind of continuous beam Demolition Construction method, it is characterised in that comprise the following steps：
(1) preparation of construction：Get out remove the plant equipment and instrument of continuous beam；
(2) bridge deck is removed：Bridge deck remove include bridge floor pitch remove, expansion joint dismounting,
Anti-collision wall is removed；
(3) bearing is locked：In bearing surrounding 20mm steel plate connects bearing upper and lower cover platess, weldering
Connect firmly, lock bearing；
(4) support is set up：Continuous beam removes support system by HR100 portal supports, regulation
Bar, in length and breadth intertie, horizontal reinforcing bar, bridging, adjustable frames and bracket, wood stupefied
Distribution beam is constituted；
(5) box beam is cut：Bridge is divided into recycle after some pieces and meets tonnage demand
Loop wheel machine lifting landing, the first longitudinally cutting transverse cuts again of main line continuous beam, ring road continuous beam is direct
Transverse cuts, box beam cutting is using the cutting of electronic rope saw cut system, in units of connection, main line
The left width of bridge and the cutting of right width widened section are carried out by order horizontal behind first longitudinal direction, the right width mark of main line bridge
Quasi- section and each ramp bridge only carry out transverse cuts；
(6) beam block is removed：After the completion of box beam segmentation cutting, lifted and cut from crawler crane
Beam block lands；
(7) bridge pier is removed：Remaining bridge pier part is cut using pick machine.
Bridge floor pitch is used on LXH1300D type pitch milling machine millings, bridge floor per 150m conducts
