Description
Technical field
The invention belongs to Municipal Engineering Construction technical field, the construction party of beam is shipped more particularly to a kind of cross by railway
Method.
Background technique
With the continuous progress of Urbanization Progress, the existing highway communication in city has been unable to satisfy present situation transport need, therefore
It needs largely to reconstruct, enlarging, newly-built municipal highway traffic, but since existing railway route plan mostly, it is more early to build, railway is all
Side infrastructure construction is substantially perfect, this has resulted in the shape that new (changing) builds municipal highway route Yu existing railway crisscross traffic
Condition increases significantly.Past highway and railway intersection generally use level crossing, when train passes through above-mentioned level crossing, highway
Temporarily break off a friendship.But with the quickening of the railroad train speed of service and the increasing of freight volume, the existing peace of this level crossing
Full property difference and the drawbacks of influencing highway normal traffic, day by day show, therefore are gradually changed to intersection, on point across and undercrossing tunnel
Two ways makes highway and railway separate operation, substantially increases safety.In upper across mode work progress, new highway
Bridge is faced with that railway two sides town and country existing building is more, influences the current situation of Beam-transporting Vehicle, and due to Beam-transporting Vehicle category
It in overlength, transfinites, overweight vehicle, therefore existing urban and suburban roads is difficult to meet its passage condition.If the newly-built road Yun Liang detoured,
Removal need to be reorganized, cost is too high, and the duration not can guarantee；According to newly-built temporary road degree of lip-rounding formula, then it is unfavorable for traffic safety,
And construction cost is high, and long construction period not can guarantee the duration.
Summary of the invention
To solve the above-mentioned problems, the purpose of the present invention is to provide a kind of crossed by railway to ship the construction method of beam.
In order to achieve the above object, provided by the invention to cross that ship beam construction method include carrying out in order by railway
The following steps:
1) muti-piece plate steel platform is made, four corners reserve a towing pad respectively on steel platform surface and setting one rises
Drop formula universal wheel；
2) one layer of aggregate chips is first laid on the ground of two existing railway two sides in construction area, then on aggregate chips layer upper berth
If one layer of protection steel plate, to be protected to existing cable；
3) supporting module on the ground on protection steel plate and between two existing railways, and coagulation is poured in template
Soil and two interim side piers and a Temporary central pier is made, wherein pier top surface in side is interior in high outside and low outside faulting of slab ends shape
It is flushed at the top of side top surface and rail；It is flushed at the top of the top surface of Temporary central pier and rail；
4) fill two-ash broken stones slope on the outside ground of side pier, and be compacted with small rammer, with the road Yun Liang
Road drop-over；
5) one layer of lumps of wood, lumps of wood both ends difference are laid with along perpendicular to rail direction on two rail of every existing railway
It is placed on the inside top surface of interim side pier and the top surface outside left of Temporary central pier, then edge is parallel on the lumps of wood
Rail direction is laid with one layer of plank and forms lumps of wood boarding；
6) steel platform is supported using jack, adjusts lift universal wheel and stretches out idler wheel thereon under steel platform
End, then the wirerope on loading machine is fastened on towing pad and steel platform is drawn in lumps of wood boarding, then with very heavy
Topmast props up steel platform, adjusts lift universal wheel and makes inside idler wheel retraction steel platform thereon, and unloading jack keeps steel flat
Platform falls in lumps of wood boarding surface, and support pad is firm, successively draws muti-piece steel platform and continuous laying is in every existing railway
In lumps of wood boarding；The gap on two existing railways between steel platform is filled using sleeper pier later；
7) column inclined-plane steel support is laid in the outer top surface of each interim side pier, and by pre- on interim side pier
It buries bolt the support of inclined-plane steel and interim side pier are fixed together；The outside inclined downward in surface of inclined-plane steel support, at this time inclined-plane steel
The inside top of support is flushed with steel platform surface；
8) after the completion of above-mentioned construction, Beam-transporting Vehicle is flat by two-ash broken stones slope, the support of inclined-plane steel, steel from existing railway side
Platform is moved to the other side；
9) after every completion a batch fortune beam task, unscrew pre-embedded bolt first, remove the support of inclined-plane steel, withdraw from sleeper pier；Later
Steel platform is supported using jack, adjusts lift universal wheel and the idler wheel that makes thereon stretches out the lower end of steel platform, utilizes dress
Carrier aircraft is successively drawn muti-piece steel platform and is removed；Last manual demolition lumps of wood boarding, restores existing railway operation；
10) when needing to transport beam again, step 5)-step 9) is repeated, after the completion of all beams all transport, is removed interim
Side pier and Temporary central pier withdraw from protection steel plate, restore existing railway original state.
In step 1), the steel platform is made of steel plate panel, plurality of steel plates bottom plate and Duo Gen I-steel；Wherein steel
Plate face plate is rectangle structure, is horizontally disposed with；More I-steel spacing distances are arranged side by side, and upper end wing plate is welded on steel plate panel
