I-4, pipeline is lifted on this carriage gets final product.
Because the present invention has adopted above technological scheme, can guarantee the required precision of engineering, can avoid the danger of high-lift operation again.Simultaneously, because piping erection under the bridge tripe, is overlooked at all and be cannot see, thereby can improve the city look and feel in city, to meet the requirement of current city construction.
Present device has following effect when using:
1, because the objective condition of construction does not possess lifting head-room clearance (only 250mm), therefore can not use hanging device to construct, so adopt pipeline vertical-lift platform to carry out vertical-lift.Require the axis that the center of lifting platform must the align with tube design centre, utilize oil hydraulic pump that steel pipe is promoted to setting height(from bottom) under the bridge base plate then.
2, because lifting platform can only be fixed on the point, therefore also can only solve steel pipe height problem in transit, and the skyborne level transportation of steel pipe waits to solve.For this reason, supporting fortune pipe dolly and installation and maintenance dolly have been designed.Fortune pipe dolly has 2, and stride with end bay at main bridge center respectively 1.Because main bridge center is striden with the end bay structure entirely different, so the fortune pipe dolly of end bay can only be transported to steel pipe the intersection that stride at end bay and center, thereby main bridge center is striden a fortune pipe dolly also need be installed, on this dolly pulley is housed, available traction method is drawn to main span fortune pipe dolly to the steel pipe on the end bay fortune pipe dolly and gets on, and then is transported to the mounting points of main span.2 fortune pipe dollies are installed on the light rail, promote with manpower.And main span has 1 suspension type maintenance dolly in addition, is suspended on its roller in the notch of 2 channel-section steels, and channel-section steel then is laid in below the suspension rod, and the insurance limit stoper is housed, and guaranteeing the reliable and secure of dolly, also can not degenerate in the river even trolley idler wheels is overstepped the limit.Its purposes is maintained also device effect except the external pipeline maintenance from now on of pipe laying.
3, because bridge tube is consistent with the gradient of bridge, ascents and descents is also arranged, so must be controlled to the gradient of pipeline.Utilize the screw thread of the suspension rod lower end of sprung parts to regulate, can make the design grade of pipeline obtain guaranteeing comparatively accurately.

Describe method of construction of the present invention in detail for an embodiment below.
The river crossing bridge pipe of 790 meters of one total lengths for example is installed, and wherein main bridge center is striden 230 meters, each 280 meters of two end bays.Main bridge center is striden and is passed through certain waters main stem, dried up about 15 meters.Diameter is that the tap water cross under of 900mm (DN900) is this bridge conveyance system.According to the pipeline absolute altitude that designing institute provides, the only surplus 250mm of spacing of back pipeline end face and bridge base plate is installed, therefore do not possess the lifting head-room clearance.Wide because of the waters, wind-force is big, and hanging operation is greatly dangerous.The objective condition of construction is quite abominable.
According to method of the present invention, main bridge center is striden 230 meters in the centre, and the employing locking hood type soars under the bridge tripe that is suspended on highway bridge; Other two end bays are to pass bridge pier for each 280 meters, are installed in the culvert hole of the original box structure of highway bridge, then adopt the suspension type fixed installation.
At first carry out pipeline and carry out the assembly unit welding: earlier pipeline vertical-lift platform is positioned over limit spanning one side; Be positioned under the bridge tripe tubing position below use the steel plate passage that the bridge main body structure is laid a belt track, place two fortune pipe dollies under the spanning of limit respectively and on the track of main spanning lower steel plate passage; Be positioned in main spanning and lay a pair of chute under the bridge floor of tubing position, the installation and maintenance dolly is hung in the chute under the main spanning; With crane steel pipe is hung on the pipeline vertical-lift platform, and the axis of controlling plumbing fixtures design centre must aim at the steel pipe set-point at lifting platform center, utilize oil hydraulic pump the setting height(from bottom) of steel pipe jacking to the bridge base plate; By the pulley on the fortune pipe dolly and cucurbit with on the lifting platform on the fortune pipe dolly of jacking under to the steel pipe traction of setting height(from bottom) to the limit spanning; With fortune pipe dolly pipeline is transported to assembly unit soldering point (cooperating referring to Fig. 4), utilize the chain hois on the maintenance dolly again, pipeline on the fortune pipe dolly is sling (cooperating referring to Fig. 5), withdraw from fortune pipe dolly, adjust the pipe height to designed elevation, match with the port in last pipe joint road, promptly carry out the assembly unit welding.For guaranteeing welding quality, require the method for inspection that adopts dye penetrant inspection and radiographic inspection to combine.
Adopt suspension rod to hang (cooperation) with carriage in involutory pipeline 8, make the conduit bracket of main spanning become locking hood type referring to Fig. 7.Because main spanning is different fully with the crossstructure of limit spanning, the limit spanning is installed in the culvert hole of box structure, and main spanning does not have the culvert hole of box structure, so adopt anchor ear to fix.But both have a common ground, all are to utilize giving on the bridge deck 7 to box out for 71 (cooperating referring to Fig. 6).For example stride per 2 meters one grade is provided with giving of 2 φ 30mm and boxes out at main bridge center.Utilization is given and being boxed out, and penetrates the suspension rod of φ 23 * 1560, and there is the M22 screw thread at suspension rod two.Suspension rod needs through preservative treatment, before bridge floor is not built, insert to give by bridge floor and box out, with the metal mat of the contacting point cushioning 100 * 100 * 10 of bridge deck.The screw via hole that the carriage two ends are held by conduit bracket in the bottom surface of steel pipe is connected with suspension rod.
Again steel pipe is carried out preservative treatment.The internal and external anti-corrosive of every joint steel pipe is all handled on the ground in advance, lifting splicing then, and just interface internal and external anti-corrosive partly needs to carry out after the assembly unit welding.Anticorrosion because caliber very big (DN900) in wherein, can be directly by the workmen pierce in the pipe gunite with in the complete driving fit of interior anticorrosive coat of processing, must not leave the slit; Outer anticorrosion construction personnel can stand on the maintenance dolly and finish, and brushing epoxy chlorine tincture rubberbase paint is to prolong the life-span of steel pipe.
