Barrel assemblies is made up of four cylinders 1, and four cylinders 1 are parallel and in constituting rectangle, for as
Support structure, four cylinders 1 are all reinforced concrete structures.
Wherein, each cylinder 1 is hollow type, and inside top wall is both provided with ring bracket structure 6, ring
The bracket end face of circle bracket structure 6 arranges caulking gum packing ring;Ring bracket structure 6 is for placing correspondence
Cylinder top cover plate 2.Wherein, the race diameter of each cylinder 1 is 9.0m, wall thickness 0.25m, height are 6.5m,
The end face width 0.3m of ring bracket structure 6, away from barrel end face 0.5m, single cylinder 1 weight 125 tons.
Cylinder top cover plate assembly is made up of four cylinder top cover plates 2, and each cylinder top cover plate 2 is individually positioned in
On corresponding ring bracket structure 6, lay degree for labelling cylinder foundation trestle work structure.Wherein, often
Individual cylinder top cover plate 2 diameter 8.4m, edge thickness is 0.5m.
Circular abutment assembly is made up of four circular abutments 3, each circular abutment 3 fixing connection correspondence
Cylinder top cover plate 2 is integrally formed;Wherein, the side, top of each circular abutment 3 is both provided with bracket structure 7;
The bracket structure 7 of four circular abutment 3 sides is divided into two groups, and two bracket structure 7 opposition often organized are arranged,
It is used for placing crossbeam 4.The edge thickness of circular abutment 3 is 0.8m, and external diameter is 1.5m, wall thickness 0.3m, high
Degree 5.0m, the end face width 0.5m of side, the top bracket structure 7 of circular abutment 3, one group of cylinder top cover plate 2
With circular abutment 3 weight 108 tons.
Transverse beam assembly is made up of two crossbeams 4, and each crossbeam 4 is rigidly attached to two brackets of each group respectively
In structure 7.The high 1.5m of crossbeam 4, wide 1.5m, long 9.5m, single beam weighs 54 tons.
Floorings 5 fixed placement is on two crossbeams 4.The thick 1.0m of single floorings 5, wide 1.0m, long 14m,
Weigh 35 tons.
Preferably, in order to preferably fixing make crossbeam 4 and bracket structure 7 in being rigidly connected, cylinder foundation stack
Bridge construction also includes: the cast-in-place joint of crossbeam 8, is cast in crossbeam 4 and the junction of bracket structure 7, is used for solid
Determine crossbeam 4 and bracket structure 7.
Refer to Fig. 3 below, introduce the installation method of cylinder foundation trestle work structure:
Four cylinders 1 are hung on platform for lining 9 under water by S1 according to trestle spacing and trestle position.
Wherein, after the soft soil foundation of one piece of rectangular area is specifically made smooth process by platform for lining 9 under water,
The platform that place mat metalling and/or concrete slab are formed.
S2, lift four groups pre-with the circular abutment 3 of bracket structure 7 by cylinder top cover plate 2 and side, top
The plate part being formed integrally is correspondingly placed on the ring bracket structure 6 of four cylinder 1 inside top.
It addition, four groups of cylinder top cover plates 2 are welded on the ring bracket structure 6 of correspondence.
S3, lifts two crossbeams 4 and is placed on two groups of respective bracket structures of circular abutment 37, and will be every
Root crossbeam 4 and corresponding bracket structure 7 are rigidly connected process, to constitute two groups of structures.
S4, will connect with dismountable shaped steel 11 between two groups of structures, constitutes trestle bridge pier structure.
S5, inflates, so that trestle bridge pier structure is floating in four cylinders 1.
S6, hauls trestle bridge pier structure to infield, then pulls out the gas in four cylinders 1, make
Four cylinders 1 are lowered in soft soil foundation.
S7, adds ballast and makes four cylinders 1 sink, until the downside of cylinder top cover plate 2 and soft soil foundation connect
Touch.
S8, pours a layer concrete on two crossbeams 4 respectively, so that two with crossbeam 4 upper flat and reach
To identical height.
S9, lifting floorings 5 are shelved and are fixed between two crossbeams 4.
Illustrate underneath with concrete example.
Element precast: reinforced concrete cylinder 1, cylinder top cover plate 2 and circular abutment 3, crossbeam 4, bridge floor
Plate 5 is first the most prefabricated at land precasting yard.
Wherein, cylinder top cover plate 2 and circular abutment 3 are prefabricated integral.
Platform for lining 9 is built under water: in waters, harbour 10 forward position, by wide 24m, the rectangular area of long 28m
Weak soil sea bottom surface suitably dredge and make smooth process, the metalling that place mat 0.5 to 1.0m is thick, metalling top
Lay the thick concrete slab of 0.5m after face is smooth, form platform for lining 9 under water.When high-tide level, it is ensured that
The depth of water on platform for lining is no less than 4.5m.
Cylinder foundation trestle work structure sea is assembled, by following process by prefabricated cylinder 1, cylinder top cover plate 2,
Circular abutment 3, crossbeam 4 carry out assembly:
1) 4 prefabricated cylinders 1 are hung on platform for lining 9 under water according to trestle spacing and trestle position,
As shown in Figure 4 and Figure 5,4 prefabricated cylinders 1 are parallel to each other and constitute rectangle.It addition, 4 prefabricated
Cylinder 1 between spacing can be different, such as, side cylinder 1 center distance is 11m, opposite side circle
Cylinder 1 center distance is 15m;
2) 4 groups of cylinder top cover plates 2 and circular abutment 3 prefabricated all-in-one-piece cover plate structure as shown in Figure 6, are lifted
Part is positioned on 4 ring bracket structures 6, by the mode of pre-buried steel Member Welding by cylinder 1 and cylinder top
Cover plate 2 connects;
3) as it is shown in fig. 7,2 crossbeams 4 of lifting are positioned over 2 groups of arranged side by side two circular abutment 3 tops
On bracket structure 7, top and the crossbeam 4 of circular abutment 3 are made connection and processed, constitutes 2 groups of structures;
4) as illustrated in figs. 8-9, one will be connected into dismountable auxiliary shaped steel 11 between 2 groups of structures
Individual entirety, constitutes cylinder foundation trestle work structure, and its overall weight is about 1100 tons.
Cylinder foundation trestle work structure sea transportation by driving: when the depth of water on platform for lining is more than 4.5m as the tide rises, to
Inflation in 4 cylinders 1 of cylinder foundation trestle work structure, makes structure float, and haul is to infield.Such as figure
Shown in 10, arrow represents the direction of haul.
Cylinder foundation trestle work structure sinks to installing: cylinder foundation trestle work structure, after infield positions, is released
Gas in cylinder 1, cylinder 1 is lowered in foundation soil by deadweight, and as shown in figure 11, what arrow represented is
The direction of venting.When venting, exitting generally by air valve, air valve bottom has pipeline to pass cylinder
Lamina tecti 2 connects with cylinder 1 internal cavity, opens air valve and just can release the air in cylinder 1.Then, then
Adding ballast to make cylinder 1 sink down into cylinder top cover plate 2 downside to contact with mud face, seabed, cylinder foundation trestle is tied
Structure sinking installation puts in place.As shown in figure 12, the cylinder foundation trestle work structure of position it is mounted to.
Floorings 5 are installed: on the crossbeam 4 of cylinder foundation trestle work structure, pour one layer of blinding concrete,
Make crossbeam 4 upper flat, and make crossbeam 4 end face of all installations reach identical elevation, lift bridge afterwards
Panel 5 is shelved and is fixed on adjacent two crossbeam 4.The floorings 5 of 9 pieces of wide 1.0m are placed side by side,
Form the wide bridge floor of 9.0m.
So build trestle, floorings 5 end face away from mud face, seabed height at more than 8.3m, bridge floor width 9.0m.
By one or more embodiment of the present invention, the invention have the advantages that or advantage:
The installation method of a kind of cylinder foundation trestle work structure that the present invention provides, the fortune of cylinder foundation trestle work structure
The defeated transport barge that need not, in-site installation need not argosy and hangs, and marine on-site installation work amount is few, construction
Little by Lidar Equation, efficiency of construction and quality are high, and integrated construction expense is low.
