Detailed description of the invention
As shown in Figure 1, 2, a kind of Existing Railway Line long-span beam is maked somebody a mere figurehead system, comprises and is symmetricly set on up-downgoing railwayFour groups of tension piles 1 in line outside and be subject to piling 2, cantilever beam 3, cross bearer 4, distribution beam 5, longeron 6 and stub 7, are arranged by piling 2Apart from 7 meters, up-downgoing railway line center outside, tension pile 1 is arranged on apart from 11 meters, outside, up-downgoing railway line center; Every groupTension pile 1 and be subject to piling 2 tops that one cantilever beam 3 is set, sets up a cross bearer on the cantilever beam 3 of the up-downgoing railway line left and right sides4, cantilever beam 3 arranges rubber blanket with cross bearer bearing place, on downline axis direction two cross bearers 4, sets up longeron 6, described onUnder descending railway line, respectively set up two longerons 6, longeron 6 arranges distribution beam 5 with cross bearer 4 crossover sites, distribution beam 5 and longeron 6Between rubber support is set, described stub 7 is arranged on the below at cross bearer 4 middle parts, stable for ensureing stake position, the stake end of stub 7Be set to tubaeform.
Be subject to 1 top of piling 2 and tension pile to be provided with the fulcrum stake reinforcing bar 8 of fan-shaped layout, described fulcrum stake reinforcing bar 8 stretches into outstandingIn arm beam 3.
Specific construction step of the present utility model and points for attention:
1. tension pile and be subject to pressing pile construction
As shown in Figure 1, 2, arrange four groups of supporting piles at 7m outside uplink and downlink track circuit center, 11m place. Every group byTwo pile compositions, far-end is tension pile 1, plays uplift effect; Near-end is for being subject to piling 2, and the stake end is positioned at supporting course, plays resistance to compression and doesWith. Tension pile 1 and be subject to piling 2 all to adopt small-sized diving drill machine boring to ensure Business Line safety and stability, prevents from affecting traffic safety;Tension pile 1 is 1.25m with being subject to piling 2 diameters, because of geological condition complexity, needs to increase mud balance, ensures that pile lining is stable, lower reinforcing barBefore cage, need hole clearly, after lower complete steel reinforcement cage, need to guarantee that steel reinforcement cage stretches to cantilever beam effective length; Concrete perfusion needs the clear stake end floatingSlag and casting concrete face higher than stake at the bottom of design altitude.
2. Cantilever Beam Construction
As shown in Figure 3, it is long that fulcrum stake reinforcing bar 8 stretches into the interior 1m of cantilever beam 3, fulcrum stake reinforcing bar 8 fan-shaped layouts, tension pile 1 HeBe subject to piling 2 pile bodies to stretch into the interior 15cm of cantilever beam 3, make stake and the abundant combination of cantilever beam 3. Cantilever beam 3 assembling reinforcements, note cantilever portionDivide principal rod on top. Cantilever beam 3 adopts C35 concrete, and top pre-buried cross bearer group stopping means, adopts pre-buried Φ15cmPVC pipe degree of depth 50cm, is wearing large horizontal stroke, after 4 rear insertion channel-section steels, in filling concrete pipe, carries out spacing to circuit.
3. large cross beam
Cross bearer 4 adopts just beam of 24mD type, wears quantity and determines according to the stressed fulcrum quantity in top, and prop up and brings large horizontal stroke out into the open at a placeBeam quantity is 2, and prop up and bring cross bearer quantity out into the open at two places is 4. Before circuit built on stilts rear cross bearer 4 liftings temporarily, on cantilever beam 34800 × 300 × 37mm size rubber bearing is placed at cross bearer bearing place, and the effect one of rubber blanket is insulation, stops ruddinessBand; The 2nd, fulcrum provides buffering. After artificial shoveling finishes, utilize hoist engine (excavator) crane to coordinate and wear cross bearer, wornAfter finishing, cross bearer is bundled into entirety, top has distribution beam to connect.
4. cross bearer middle part stub construction
During Business Line is gone slowly, utilize train interval, carry out manual digging pile construction, survey crew is according to track phase in advanceCorresponding stake position is put out in contraposition, and stake footpath is 1.5m, and stake is long is 2m, and it act as and ensures that cross bearer 4 is stable, reduces mid span moment,Ensure that circuit amount of deflection meets Business Line requirement. At the bottom of 7 of stubs, be set to tubaeformly, ensure that stake position is stable, utilize train interval to digStake, the elevation discrepancy in elevation at the bottom of need guarantee height of pile top and track, guarantees the satisfied cross bearer requirement that wears.
5. the making of distribution beam and installation
Distribution beam is made: as shown in Figure 4,5, 6, adopt the laterally welding side by side of 4 32a I-steel, and at its top and the end6mm steel plate welds respectively in portion, and four jiaos of reserved four diameter 14mm holes, for being connected with cross bearer.
The mounting arrangements of distribution beam: as shown in Figure 7,8, after cross bearer installs, distribution beam is lifted to longeron bearingPlace, position and absolute altitude calibration, utilize four bolts that distribution beam and cross bearer are connected to entirety, also strengthens the whole of cross bearer simultaneouslyBody stability, makes it stressed, power transmission is even. In addition, because setting up distribution beam, the absolute altitude of cross bearer can effectively be reduced, therebyIncrease the Business Line flange of rail to cross bearer and risen poorly, in large cross beam, strengthened safety operation space, improved and worn large horizontal strokeSafety beam coefficient.
6. interim built on stilts beam construction
As shown in Figure 9, before cross bearer 4 is installed, first utilize track blockade point temporarily built on stilts to circuit. Specific construction stepRapid: the long stub of two 2m of constructing respectively in cross bearer 4 both sides, set-point along line direction, as interim built on stilts fulcrum stake 16,Interim built on stilts fulcrum stake 16 adopts manually digging hole deposited reinforced concrete pile. Treat that pile concrete reaches design strength, and check markHigh errorless after, after its intensity reaches requirement pile strength, utilize and block point and wear needle beam 15, after wearing needle beam 15 and completingDirectly just beam is placed temporarily in lifting thereon, and just beam and track sleeper interlocking are fixed and arrange after stopping means temporarily, completeCircuit is temporarily built on stilts, manually cuts the earth afterwards along cross bearer 4 axis directions, forms cross bearer installing hole, is convenient to the peace of cross bearer 4Dress.
7. needle beam and longeron construction
Longeron 6 adopts just beam of 24mD type, before longeron 6 liftings, first should adjust pillow distance. Adjust reinforcing by the spacing of 670mmSleeper pitch in scope, and unnecessary sleeper is extracted out. In the sleeper pitch of adjusting, remove part ballast aggregate and penetrate littleCrossbeam, adopts angle steel S7 location, location needle beam. And at needle beam and the rail contact-making surface pad rubber cushion that insulate well, prevent from causing signalShort circuit, last first-class rail fastening. Before longeron 6 liftings, first place rubber support 9 at distribution beam 5 fulcrum places, top. Longeron 6Lifting needs to utilize " skylight point " construction, and the front application contact net of constructing has a power failure and coordinates, and can start longeron 6 and lift after confirmation power failure.Longeron is installed and is adopted artificial truck crane or the railcar of coordinating to carry out. After longeron hoisted in position, connecting plate, bracket and oblique are installed respectivelyOther connected systems such as bar. Fulcrum place buries longeron anti-creep in advance underground, anti-traversing stopping means, and during ensureing to make somebody a mere figurehead, just beam is steady for D typeFixed.
