Abstract
The present invention relates to an integral hanging method and a special hanging device for a steel pipe concrete flexible rope arch bridge, wh belongs to the field of bridge construction. The integral hanging method for the steel pipe concrete flexible rope arch bridge uses a floating crane or caterpillar crane hanging hook to lift up the hanging device to hoist and transport the steel pipe concrete flexible rope arch bridge which is hung by the special hanging device and the integral hanging method, and a bearing way adopts the special hanging device of the integral hanging in a lower bearing type four-point hanging way; the special hanging device is composed of a hanging device main beam, a main hanging rope, a balance beam, a supporting beam and a small hanging rope, wherein the main beam of the special hanging device adopts a symmetric space truss structure. The integral hanging transportation and installation can be implemented in rivers or sea areas by using the special hanging device of the present invention, and the present invention has the advantages of good manufacturing and installing quality of the arch bridge, construction risk reduction and construction safety guarantee; furthermore, the present invention can be used for the integral erection and construction for steel pipe concrete flexible rope arch bridges of which the span exceeds hektometers.
Description
Technical field concrete filled steel tube of the present invention soft rope arch bridge integral hoisting method and special hanger belong to technical field of bridge construction, can be used for the erection construction of concrete-filled steel tubes arch bridge.
The soft rope arch bridge of the present concrete filled steel tube of background technology technology is widely used in the bridge construction, the steel pipe skeleton of the soft rope arch bridge of concrete filled steel tube is gently many compared with the bridge construction of steel concrete, but the integral erection of the soft rope arch bridge of concrete filled steel tube has sizable difficulty.For striding the footpath above the soft rope arch bridge of concrete filled steel tube more than hundred meters, the main erection method that adopts at present has three kinds both at home and abroad: the method that cable lifting cantilever is constructed; Rotation swivel construction method; Adopt the method for integral hoisting.Cable lifting cantilever job practices is that the bow member segmental hoisting is joined the two sections of a bridge, etc again.In the rotation swivel construction method, the vertical transfer method and the method for flatting turn all have application, and the method that vertical transfer is also arranged, flat turn and combine will be through processes such as closure and system conversions.More than two kinds of methods very big risk and difficulty are all arranged.In the environmental permission part, can adopt the method for integral hoisting.But the notion of integral hoisting at present is confined to the integral hoisting of monolithic arch rib basically, is not that complete arch bridge is striden in lifting one.And can only handling stride the less arch rib in footpath, be difficult to resolve the certainly soft rope arch bridge of concrete filled steel tube skeleton less difficult problem of relative rigidity when striding the footpath more greatly.
Summary of the invention the objective of the invention is to propose a kind of concrete filled steel tube soft rope arch bridge integral hoisting method and special hanger, and this is a kind of new job practices.Can solve the soft rope arch bridge of concrete filled steel tube skeleton less difficult problem of relative rigidity when striding the footpath more greatly.The soft rope arch bridge of concrete filled steel tube can be in factory building or place whole in advance the manufacturing, utilize special hanger of the present invention then, use large-tonnage derrick barge or crawler crane with the whole handling assembling of arch bridge,, guarantee the safety of erection construction with workmanship and the erection weight of guaranteeing bridge; Can be used for striding the footpath and surpass hundred meters the soft rope arch bridge of concrete filled steel tube integral erection construction.
The soft rope arch bridge of a kind of concrete filled steel tube of the technical solution used in the present invention integral hoisting method is by derrick barge or the caterpillar crane hook soft rope arch bridge of suspender lifting transportation concrete filled steel tube of slinging, and it is characterized in that: adopt the method lifting of special hanger and integral hoisting.Concrete implementation step is: will build operator's working platform 2 earlier, construction on working platform 2; Before lifting, earlier joist 3 is hung on the little hoist cable 4 in the steel pipe arch bridge arch rib outside, tangling otic placode 23 by Chain block 8 hangs on the other end of joist 3 on another little hoist cable 4 of inboard of steel pipe arch bridge arch rib, special hanger then hoists, make joist 3 and steel pipe arch bridge arch rib, it is the contact of arch bridge suspension centre, utilize the derrick barge suspension hook main hoist cable 6 of slinging, the main hoist cable 6 special hanger girder 5 of slinging, the two ends of girder 5 hang with 4 equalizer bars 7, be hung with two little hoist cables 4 under each equalizer bar, little hoist cable 4 joist 3 of will slinging, joist 3 will hold up the suspension centre of steel pipe arch bridge 1, start the lifting mechanism of derrick barge like this, the transportation installation in position of just the soft rope arch bridge of concrete filled steel tube integral body can being sling.
When steel pipe arch bridge by handling to the destination and after being installed on the bridge pier, must untie the connection of 3 pairs of arch bridges 1 of joist. the concrete practice is, the suspension hook of derrick barge descends a little, tangle by the otic placode 23 of Chain block 8 joist 3 of arch bridge inboard, pulling Chain block 8 makes the little hoist cable 4 that hangs on the arch rib inboard be in relaxed state, little hoist cable is taken, and then pull down and start to draw cucurbit 8,3 of joists are hung on the little hoist cable in the arch rib outside, Chain block 8 is taken again, finished the work that suspender and joist break away from arch bridge, special hanger can leave arch bridge, extension is plucked the joist end-of-job, and working platform 2 is promptly dismountable.
The special hanger of the soft rope arch bridge of a kind of concrete filled steel tube integral hoisting, form by suspender girder, main hoist cable, equalizer bar, joist, little hoist cable, it is characterized in that: the special hanger girder adopts the symmetrical expression space truss structure, and bearing mode adopts 4 lifting modes of lower support type;
Joist 3 is a welded construction, by joist body 17, arc plate 18, rubber arc plate 19, end casing 20, Shackle assembly 21, stiffener 22 and otic placode 23 are formed, joist body 17 is formed by three block plate assembly weldings, its cross section is the ingot shape, above with arc plate 18 welding, two ends are with end casing 20 welding, tilt to be welded with Shackle assembly 21 in joist body 17 outsides, make joist 3 hold up the arch bridge suspension centre to connect little hoist cable 4, otic placode 23 is used for the Chain block 8 rotation joist 3 of slinging, rubber arc plate 18 is bonded on the arc plate 17, rubber arc plate 18 will also be furnished with some for improving the stiffener 22 of strength and stiffness as the cushion pad of joist 3 with the steel pipe arch bridge 1 that is hung in the structure.
The invention has the beneficial effects as follows:, can guarantee the manufacturing and the assembly quality of arch bridge because the soft rope arch bridge of concrete filled steel tube is to assemble whole manufacturing of factory building or place.With special hanger integral lifting transportation and the soft rope arch bridge of concrete filled steel tube is installed, can guarantee to realize the safe construction that transports and install, solved because the less constructional difficulties of bringing of steel pipe arch bridge relative rigidity and the difficult problem of greater risk is arranged.Can be in the river or the marine site carry out the integral hoisting transportation and install, the manufacturing installation quality of arch bridge is good, can reduce construction risk, guarantees construction safety.
