Description
Technical field
The utility model relates to bridge foundation construction technologies, more particularly, to a kind of steel stack of resistance flood discharge torrent speed impact
Bridge infrastructure structure.
Background technique
In water during bridge foundation construction, logical two sides are generally drawn by the way of setting up steel trestle, form work waterborne
Industry channel, it is current for Material Transportation and construction equipment.Due to steel-pipe pile inserting piling simple process, structure stress is strong the advantages that
It is usually used in steel trestle infrastructure in water.If but in the construction of mining under reservoir region, riverbed washes away lower no weakness in reservoir spillway
Coating, surface layer are mostly gravel, cobble, under when being rock stratum condition, the infrastructure of trestle all uses inserting piling formula in water
The shortcomings that steel-pipe pile is that valid bonding length is short, is impacted vulnerable to flood discharge torrent speed in short-term, and steel trestle overall stability is caused to be deteriorated,
Unstability is in turn resulted in the negative consequences such as to collapse；And it is connected reinforced concrete drilling stake under steel-pipe pile and then needs to make in large area water
Industry, not only long construction period, and marine equipment and goods and materials investment are more, personnel's operation safety risk height.
Summary of the invention
That the purpose of this utility model is to provide a kind of speed of applications is fast, less investment, stability are good and to resist flood discharge anxious
The steel trestle infrastructure structure of flow velocity impact.
To achieve the above object, the utility model can take following technical proposals:
The steel trestle infrastructure structure described in the utility model for resisting the impact of flood discharge torrent speed, including bridge is indulged to interval
The steel-pipe pile of arrangement, the steel-pipe pile include the I fashioned iron tubular pole and II fashioned iron tubular pole of successively interlaced arrangement, the I fashioned iron tubular pole
Diameter be greater than II fashioned iron tubular pole diameter；The downward inserting piling of base opening of the I fashioned iron tubular pole extends in rock, is located in rock
I fashioned iron tubular pole in be perfused with anti-anchor concrete；The base opening inserting piling of the II fashioned iron tubular pole is to scar.
I fashioned iron tubular pole direction across bridge arranged for interval two is provided with hood type connection system between two I fashioned iron tubular poles；
II fashioned iron tubular pole direction across bridge arranged for interval three is provided with hood type connection system between adjacent two II fashioned iron tubular poles.
Perfusion depth >=5 meter of the anti-anchor concrete.
The diameter of the I fashioned iron tubular pole is 920mm, and the diameter of the II fashioned iron tubular pole is 426mm.
The base opening of the II fashioned iron tubular pole is provided with pile top.
The utility model has the advantage of quick constructions, and operating environment is good, and capital investment is few, the steel trestle lower part after construction
Base fixed can resist the impact of torrent speed water flow in short-term, and I fashioned iron tubular pole being relatively large in diameter is as strong stake, diameter lesser II
For fashioned iron tubular pole as weak stake, strong, weak stake arranged for interval had not only met the stress needs of trestle under prevailing state, but also can guarantee reservoir
The safety of flood discharge trestle at present；Guarantee that the infrastructure design of steel trestle is more reasonable, economical.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is Fig. 1 A-A to cutaway view Amplified image.
Fig. 3 is Fig. 1 B-B direction cutaway view Amplified image.
Specific embodiment
As shown in Figure 1, the steel trestle infrastructure structure described in the utility model for resisting the impact of flood discharge torrent speed, including
Along the vertical I fashioned iron tubular pole 1 that is relatively large in diameter and diameter lesser II fashioned iron tubular pole 2 of the bridge to successively interlaced arrangement, it is contemplated that safety
Factor, under normal circumstances, the diameter of I fashioned iron tubular pole 1 select 920mm, and the diameter of II fashioned iron tubular pole 2 selects 426mm, can make in this way
The vertical bearing capacity of bridge is by I, II fashioned iron tubular pole (strong and weak stake) shared, and the horizontal force that flow force generates is then by I fashioned iron
The strong stake of tubular pole 1() it undertakes.When construction, the base opening of I fashioned iron tubular pole 1 passes through the downward inserting piling of boulder bed 3 and extends at least five in rock 4
Meter, at least 5 meters of the perfusion depth of the anti-anti- anchor concrete 5 of anchor concrete 5(is perfused in the I fashioned iron tubular pole in rock)；Ⅱ
The base opening of fashioned iron tubular pole 2 is provided with pile top 6,6 inserting piling of pile top to scar；Due to being relatively large in diameter for I fashioned iron tubular pole 1, direction across bridge
Arranged for interval two, it is 1.1 that hood type connection is provided between two I fashioned iron tubular poles 1, as shown in Figure 2；II shape steel tube
2 diameters of stake are smaller, and direction across bridge needs arranged for interval three, and hood type company is again provided between adjacent two II fashioned iron tubular poles 2
Connecing is 2.1, as shown in Figure 3.
Construct steel trestle when, first by crawler crane erect-position in constructed bridge floor or on the bank beach using outstanding play to I type
Steel-pipe pile 1 and II fashioned iron tubular pole 2 carry out inserting piling, and the lesser II fashioned iron tubular pole 2 of diameter passes through boulder bed 3 by the pile top 6 of base opening
The top surface for reaching rock 4, it is fluted in the top opening setting of II fashioned iron tubular pole 2, for the insertion of distribution beam, distribution beam and trestle master
Beam is closely connected, and installing hood type connection between II fashioned iron tubular pole 2 of adjacent direction across bridge later is 2.1；I fashioned iron tubular pole, 1 base opening is inserted
It beats to behind the top surface of rock 4, first welds interim bracket to two sides along bridge, then put distribution beam and trestle girder is closely connected, later
Trestle girder top surface is laid with assembled steel floorings, but I fashioned iron tubular pole, 1 top side location is not laid with assembled steel floorings, when to
Assembled trestle girder is more than the I shape steel tube row of piles of the row away from greater than the assembled behind two holes, near the I fashioned iron tubular pole 1 of row
Percussive drill is set on steel bridge deck, using I fashioned iron tubular pole 1 do casing carry out hole milling and with proceeding to designed elevation in rock stratum 4, cut
Except interim bracket, above moves to designed elevation position and weld formal bracket with tubular pole again, adopted between distribution beam and trestle girder
Closely knit with steel plate pad, cutting I fashioned iron tubular pole, 1 top opening is concordant with trestle girder, fills inside I fashioned iron tubular pole, 1 lower end later
Anti- anchor concrete 5 forms anti-anchoring pile, and it is 1.1 that hood type connection is finally installed between adjacent I fashioned iron tubular pole 1 of direction across bridge, completes
All constructions.
