Specifically, large-span oblique crossing Frame Bridge undercrossing tunnel provided by the utility model exempts to resist traversing anchoring wire road strengthening construction
A kind of specific embodiment of technique is as follows.
Preparation of construction:
1, frame structure is contained prefabricated, maintenance and is completed, and intensity arrived design requirement；The pile foundation engineerings such as fender pile, support stake are
It completes；The construction of roadbed grouting and reinforcing finishes, through examining bearing capacity to meet the requirements.
2, optical cable, cable are manually verified, and complete move change or poling protection.Apparent safety nameplate is set.
Security protection has worked in place.
3, to rail conditions, gauge, pillow away from, vehicle flowrate, cargo dead-weight, busy idle etc. sufficiently investigated, route adds
Gu scheme and consolidation time it has been determined that and sufficiently linked up with railway department, reach an agreement.
4, track strengthening material, machinery, personnel are in place.Scene carried out safely, confide a technological secret.What track strengthening used
Compliance inspection is carried out after the materials arrivals such as stringer, crossbeam, disk button steel pipe frame, is checked and accepted, it is qualified through detection.
Wear lateral I-steel:
1, crossbeam 70 uses I45 (Type B) I-steel, arranges perpendicular to line direction, is divided between existing line concrete crosstie
0.6m, crossbeam 70 are inserted between existing pillow, and the insertion of crossbeam 70 is using " inserting a method every six " circular insertion.70 spacing frame structure of crossbeam with
It is interior (to insert 5 by 5-0-5 arrangement and stay a hole), it (inserts 2 by 2-0-2 arrangement other than frame structure and stays a hole).I-shaped steel joint uses two
Block 20mm thick steel plate is arranged that M20mm high-strength bolt connects, connector interlaced arrangement, and connector to be avoided to be located at track by clamping plate shape
Underface.
2,70 supporting point of crossbeam in frame structure: end in place is supported on the I-steel at the top of steel pipe support, and jacking end is supported on
Frame structure top surface, between supported with coaster and sheeting caps；Frame structure 70 supporting point of outer crossbeam: it is supported in two sides line protection dowel crown beam
On.
3, penetrating for work steel is divided to two groups from route both ends while being carried out, and is manually opened between existing pillow using " inserting a method every six "
Then slot is inserted into using crane, artificial assistance.Slot bottom is located at track lower outer, buries short sleeper, supports lateral I-steel,
It is separated between I-steel and track using bamboo slab rubber, and urgent with wooden wedge.I-steel is inserted into one, in time later ballast aggregate, smashes
Gu closely knit, can carry out next work steel penetrates construction." the short lumps of wood+angle steel " limiting device is installed on the outside of track.
Set up stringer I-steel:
To increase rigidity and stability, in two sides, road shoulder sets 2 road length stringers altogether, wherein the every Shu Junwei 2 in two sides road shoulder position
× HN900 × 300 × 16 × 28 section longitudinal beams composition.Every beam stringer center tap uses interlaced arrangement form, and work steel connector is adopted
It is arranged with two blocks of 32mm thick steel plates by clamping plate shape, the connection of M30mm high-strength bolt.Stringer is located on crossbeam 70, is hung using crane
Dress, the mode of hand fit are in place, and stringer is connect with crossbeam 70 with U-typed card, and stringer both ends and midfeather use sleeper pile
Support.
Route resists traversing:
1, route holds anti-shifting stake and crown beam to cancel in place, and replacing is disk button steel pipe frame and top I-steel.Route
70 one end of reinforcing crossmember rides over frame structure top surface, and one end rides on the I-steel at the top of steel pipe frame.Disk button steel pipe frame and top work
Word steel carries out diagonal brace reinforcing, plays the role of a support route.
2, stent base carries out concrete hardening.Bracket is set up, and 6 rows are laterally arranged in frame body, and longitudinal length is the same as track strengthening width
Unanimously, lateral, longitudinal pitch is 0.6 meter, is highly calculated downwards by lateral I-steel, and deducting I-steel height is frame body height
Degree, cloth is away from 1.2 meters.
3, cradle top first places 15 I-shapeds by root in frame body jacking by 0.6 meter of frame body horizontal spacing along jacking direction
Steel.45b I-steel is placed along line direction "-" type in 15 I-steel top surfaces, and front and back setting is two rows of, and high infraversion malposition is made into L-type.
4, after I-steel installs, the crossbeam 70 of track strengthening is fixed on crown beam.Lateral I-steel and crown beam work
Each crosspoint of word steel is respectively adopted two U-typed card connections and is fixed.It is inserted with plank in U-typed card top surface backing plate gap
Tightly.While jacking, there is special messenger to observe the straight situation of crown beam I-steel, the elastic situation of butt joint is checked
And reinforcing.It notes abnormalities, processing in time or pause jacking.
5,5 tons of chain blocks, 20 wirerope are used uniformly every 3 meters of setting anchor bar pull rings in frame structure top plate tail portion
Track strengthening system is tensed, unified command, special messenger commander in jacking, with jacking with tension route.Contain and cross to reduce frame structure
The frictional force of beam 70 places coaster 50 between crossbeam 70 and frame structure contain top plate.
Jacking is tried to examine:
Crossbeam 70, stringer install, and steel pipe support and top I-steel install, and 70 both ends of track strengthening crossbeam are
It is firm to support, and pull ring route tenses, and operator in place, after everything in readiness, carries out examination jacking.While jacking, group
Special messenger's whole process observes the straight situation of track and the straight situation of cradle top I-steel, and rear is commanded to add for individual cucurbits
It is fast or slow down tension speed.Putting the extreme direction before jacking individually when discovery route has dimpling metaboly, illustrates that this cucurbit is drawn
Tight speed is not able to satisfy route and resists traversing requirement, to accelerate speed tension.Whole process, special messenger commander, by adjusting individual hands
The tension speed of cucurbit is drawn to guarantee that route is straight.When discovery is regulated the speed, bending deformation without diminution trend, also be used in a hurry
Intercom notifies the pause jacking of jacking construction backstage, ascertains the reason, again jacking.When carrying out vehicle, jacking is fixed tentatively, road is kept away under worker
Vehicle, the lower support timber wedge of crossbeam 70 are urgent.Each top journey terminates, and will check transverse and longitudinal beam, holder part, it is ensured that do not have
Bending deformation, it is working properly.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
