Description
Technical field
The invention belongs to a kind of pipe bridge construction methods of installation, and in particular to large span cross the river pipe bridge interior conduit means of transport and
Construction method.
Background technique
With the development of the society, the development in city, city integrated pipe network also gradually extends outwardly, when pipeline route is through crossing the river
Bank washes away the river that serious, Scour and Accretion is irregular, flow velocity is big, riverbed trench digging is difficult or some navigations are frequent and needs often to dredge
When road, system of laying is often maked somebody a mere figurehead using pipeline, i.e., sets large-span steel pipe bridge on river.Pipeline is laid in pipe bridge.
Pipe bridge construction often makes separate tenders with pipeline construction, carries out pipeline construction after pipe bridge construction is complete.Because of pipeline aerial crossing river distance,
Some reach hundred meters of long left and right.Integral hoisting needs the crane of very large-tonnage, and construction cost is high, and the feelings constructed in pipe bridge
Under condition, integral hoisting is not easily accomplished.It is pulled according to elevator, because pipeline is long, sliding friction is big along the line, generates to pontic very big
It impacts and is easy to destroy the external anti-corrosion layer of pipe.
Summary of the invention
The present invention is to solve the transport of background technique high and medium long range pipe bridge interior conduit, installation inconvenience, pipeline in transport
The problem of Wai Fang forum is easily damaged.
To solve the above problems, the present invention one is to provide one kind and can temporarily install, be finished dismountable transport device, second is that
The method of this device transport pipeline in pipe bridge is provided.
A kind of pipe bridge interior conduit transport device, it is made of transmission mechanism and fixed mechanism；Fixed mechanism includes support, card
Plate and connecting plate, snap-gauge is affixed with support, and snap-gauge is equipped with the card slot shape cooperated with the H profile steel wing plate shape of pipe bridge bottom,
Connecting plate connection is located at the snap-gauge of H profile steel two sides；Transmission mechanism includes column, roller bearing, rubber slab and coupling beam, and roller bearing is by round steel
Core pachydermia pipe composition, pachydermia pipe movable set is on round steel inner core, one layer of rubber slab of pachydermia pipe outer cladding；Two side axle of round steel inner core
End is connect with column, and column bottom is equipped with several bolts hole；Vertical affixed connection steel on the support, connection steel are equipped with several
Bolt hole, column with to connect steel bolt affixed；Coupling beam connection is located at the column of H profile steel two sides.
Preferably, strut length is less than the spacing of support of pipelines relative seat, after column is fixed on the support, at the top of column
Roller bearing be higher than support of pipelines.
The present apparatus cooperates hoist engine transport pipeline, reduces the frictional force along pipeline traction, ensures the external anti-corrosion layer of pipeline
It is not destroyed.
The construction method that pipeline transportation is carried out using above-mentioned pipe bridge interior conduit transport device, is followed the steps below:
1) the backed snap-gauge of two cuffs: being first stuck on the top flange plate of pipe bridge bottom H profile steel by the installation of device,
Its card slot and H profile steel top flange plate cooperate, and inner side edge is contacted with H profile steel web, and bottom edge is contacted with H profile steel lower flange；With
The snap-gauge of H profile steel two sides is connected and fixed by connecting plate and bolt；Transmission mechanism is installed, coupling beam is fixed on the support of H profile steel two sides
The column of two sides；
2) pipeline transportation: installing a set of transport device in upper each H profile steel along pipe bridge installation, all roller bearings constitute one
First root canal road, is then placed on the transport device of pipe bridge beginning position by supply line, places in pipe bridge terminal
Hoist engine gently pulls pipeline, and pipeline is made to pass through each transport device one by one, and the Forward gentle along supply line then connects second
Root, third root are in place to all pipeline transportations, and entire pipeline installs；
3) it removes device: after Pipe installing is complete, first removing the connection bolt and coupling beam of column and connection, it is then light with hand hammer
Striking column falls on column on support, falls back to pipeline on support of pipelines；It finally removes connecting plate and unlocks two snap-gauges, use is small
Hammer beats the end of snap-gauge, and fixed mechanism is removed.
Horizontal transporter structure disclosed by the invention is simple, and the waste material that construction site can be used is made, cost
It is low, and can Reusability, avoid the waste of material.This method is simple to operation, and construction cost is low, does not destroy pipeline configuration, peace
Quan Xinggao, working effect are high.
