Without loss of generality, although the present embodiment is carried out when design parameter is related to as a example by regenerating the laying of waterpipe 2
Illustrate, however its do not constitute to the application sleeve pipe 1 in roughing-in method the scope of application limitation.It should be understood that
It is that the other forms pipeline in addition to waterpipe 2 is regenerated lays, it can also apply roughing-in in the sleeve pipe 1 of the application
Method.
The method of roughing-in is comprised the following steps in the sleeve pipe 1 of the present embodiment：
S1, the installation support member in sleeve pipe 1；
S2, the entrance point port installation waterwall 5 in described sleeve pipe 1, and set on the waterwall 5 of the entrance point port
Put the poling hole of pipeline；
S3, pipeline end install pipe plug after, the end of the pipeline is penetrated into described sleeve pipe 1 by the poling hole
It is interior, to block the poling hole；
S4, in described sleeve pipe 1 inject liquid with to enter described sleeve pipe 1 in pipeline apply buoyancy；
S5, the pipeline is pushed or pulled into described sleeve pipe 1；
S6, the liquid emitted in described sleeve pipe 1 so that pipeline falls on the support member and fixed.
In the method for the present embodiment, waterwall 5 is installed in the entrance point port of sleeve pipe 1 and gear is blocked in end using pipeline
Poling hole on waterwall 5 so that liquid can be injected in sleeve pipe 1 and applies buoyancy with to pipeline.After injection liquid, sleeve pipe is entered into
Pipeline in 1 is subject to buoyancy straight up, so that the active force needed during pipeline laying reduces, to reduce to applying
If the requirement of equipment and complex operation degree, the security and laying speed of construction are improved, and ensure pipeline laying in place.This
Outward, pipeline sleeve pipe 1 is driven after being installed in advance due to support member again, therefore can prevents support member from damaging deformation；Together
When, the frictional resistance that pipeline is subject under buoyancy reduces, such that it is able to the outer anti-corrosion of effective protective conduit.
Wherein, when after pipeline sleeve pipe 1 in floating or suspended state, namely liquid is applied to pipeline in sleeve pipe 1
Plus buoyancy not less than the interior conduit of sleeve pipe 1 gravity, now due to almost not rubbed between pipeline and support member, therefore
The outer anti-corrosion of pipeline can obtain optimal protection.
It should be noted that the present embodiment middle sleeve 1 and pipeline are two independent concepts, pipeline is including sleeve pipe 1
Only refer only to the pipe fitting being laid in sleeve pipe 1.
Wherein, in S1, the installation of support member can include：
Mounting platform 4 is set in sleeve pipe 1, and track is fixed on the mounting platform 4；
The support member is installed at interval in orbit.
Wherein, the concrete platform that mounting platform 4 can be formed using C20 concretings, and can be pre- by track
It is embedded in concrete platform.On this basis, support member is spaced apart along the length direction of track.Support member is preferably still
It is necessarily more typical steel bracket 3, so as to conveniently draw materials.Wherein, the size of steel bracket 3 is again according to the chi for treating roughing-in
Depending on very little so that the bearing-surface that steel bracket 3 is formed just matches with pipeline external surface.
Certainly, the mounting means and concrete structure of support member are not enumerated by the present embodiment and limited, as long as it can be supported
And the stabilization interior conduit of sleeve pipe 1.
It is noted that S1 can be carried out before S2, it is also possible to carry out after s 2, it might even be possible in the laggard of S3
OK.Likewise, the numbering before other steps does not constitute the limitation to the step execution sequence yet, the numbering in the present embodiment is
In order to avoid repeating the particular content of certain step, excessive explanation is hereinafter no longer done.
In S2, waterwall 5 can up be installed since the upper surface of mounting platform 4, refer to Fig. 2, wherein waterwall 5
In the top of mounting platform 4.Or, waterwall 5 can also be arranged on the outside of mounting platform 4 and since the inner surface of sleeve pipe 1
Install.Wherein, the height of waterwall 5 refers to Fig. 2, does not completely enclose the port of sleeve pipe 1 due to it, therefore installs gear
Sleeve pipe 1 can also be passed in and out after waterwall 5 carries out some basic constructions.
It should be appreciated that the height of waterwall 5 herein, it can be set according to level value predetermined in sleeve pipe 1
Meter.Also, on the premise of meeting setting liquid level requirement, the height to waterwall 5 does not do other requirements.Certainly, waterwall 5
Specific constructive form and material it is unrestricted.
Additionally, the poling hole on the waterwall 5 of entrance point port, its position determines according to the position of laying of pipeline, to protect
Card pipeline is passed through after poling hole sleeve pipe 1, is nearly seated at the surface of support member.Also, in order to prevent pipeline from entering
Enter after sleeve pipe 1 and support member collides interference, the height in preferred pair poling hole is designed, with so that being entered by poling hole
The pipeline of sleeve pipe 1, its bottom surface is higher by certain position than the bearing-surface of support member.
To prevent leak between pipeline and poling hole, the collar 6 is preferably installed at poling hole, and in the collar 6
Sealing collar 7 is installed.Wherein, the collar 6 is preferably still necessarily steel collar 6 and is fixed in advance in the installation process of waterwall 5
In waterwall 5.Sealing collar 7 is fixedly mounted along the inner surface of the collar 6.
On this basis, in order to prevent pipeline uneven to the power that sealing collar 7 applies, preferably along the collar extension of the collar 6 week
To multiple locating parts are distributed with, the locating part can ensure that the collar 6, sealing collar 7 and pipeline are concentric all the time, so as to prevent pipeline inclined
, there are the phenomenons such as damage, leak to avoid sealing collar 7 in the unbalance stress of sealing collar 7 caused by heart play.For example, when pipeline is subject to
During the upward play of buoyancy, if the not locating part, then the active force that the top of sealing collar 7 is subject to is larger, now may
There are the phenomenons such as damage, leak on the top of sealing collar 7.Wherein, the quantity of locating part is unrestricted, and preferably but necessarily edge
The collar 6 circumferentially to be uniformly distributed.
In the present embodiment, locating part is preferably the fast pulley 8 being fixed on the waterwall 5.In the case of this kind, work as pipeline
It is rolling friction due to what is produced between pipeline and fast pulley 8 during extruding fast pulley 8, the frictional force is very small, such that it is able to keep away
Exempt from pipeline to be scraped off.
Further, in order to prevent pipeline for scratch, slurries generally are lubricated in pipeline outer wall brushing, to reduce sealing collar 7
With the frictional resistance of pipeline lateral wall, and the outer anti-corrosion of pipeline is protected by.Additionally, lubrication slurries also have Packed effect, can
Effectively to prevent water in sleeve pipe 1 from outflowing.
It is noted that waterwall 5 can also be set in the receiving terminal port of sleeve pipe 1, to prevent receiving terminal correspondence work
Make 11 internal water accumulations of hole, cause to need to inject more liquid when liquid level reaches setting height in sleeve pipe 1.Certainly, even if sleeve pipe 1 connects
Receiving end port is not provided with waterwall 5 and nor affects on laying for the present embodiment pipeline.
In S3, by blocking pipe end, it is ensured that during pipeline is advanced to receiving terminal, liquid will not be through pipeline
Outflow, and liquid provides certain buoyancy to pipeline in sleeve pipe 1, so that for pipeline laying provides a drying, the work of safety
Space.As for the pipe plug installed in the end of pipeline, its form is unrestricted, as long as closure can be realized to prevent water excessive
.It is for instance possible to use blind plate is used as the pipe plug, and the blind plate can be embedded in pipeline inside simultaneously and table in the pipeline
Face interference fit.Additionally, pipe plug can take out after last pipeline laying completion from the receiving terminal of sleeve pipe 1.
It is water preferably to the liquid injected in sleeve pipe 1 in S4.Wherein it is possible to by presetting level value, to ensure that liquid is high
When degree reaches default level value, the buoyancy that pipeline is subject to meets specified conditions.Certainly, injection liquid is different, its setting liquid level
It is different.
For example, to cause that buoyancy that pipeline is subject to is equal to the gravity of the pipeline in sleeve pipe 1, it is passed through in sleeve pipe 1
Be water, then according to Archimedes's formula ρWatergVRow=mg, can obtain VRow.Wherein, ρWaterIt is the density of water, VRowFor pipeline is every
One meter of corresponding displacement of volume of push-in, mg is one meter of weight of above-mentioned regeneration waterpipe 2, is regenerated with the steel of a diameter of 1200mm
As a example by waterpipe 2, its every meter weight is 0.667T.Further, according to VRowCan be obtaining setting level value.
Even if certainly it should be noted that the liquid being passed through in sleeve pipe 1, it is less than sleeve pipe to the buoyancy that pipeline applies
The gravity of the pipeline in 1, but as long as certain buoyancy can be applied to pipeline, then its effect is equivalent to reduction pipeline and is subject to
Frictional resistance, such that it is able to facilitate laying for pipeline.
When liquid is less than the gravity of the interior conduit of sleeve pipe 1 to the buoyancy that pipeline applies in sleeve pipe 1, in order to prevent pipeline
External anti-corrosion layer and support member are scraped damage when contacting, and can be selected after pipeline is installed in place in sleeve pipe 1, then give pipeline appearance
Face coats outer anti-corrosion.Certainly, in the prior art, the outer anti-corrosion of pipeline is typically all just to have been completed before pipeline laying.
With the propulsion of pipeline, if being not excluded for partially liq, then the liquid level in sleeve pipe 1 will change.This implementation
In example, in order that obtaining liquid level remains at setting height, preferably opened up for adjusting liquid in described sleeve pipe 1 on waterwall 5
The spout hole 9 of position, to cause that pipeline often advances certain distance, the liquid for just having respective volume overflows from sleeve pipe 1, it is ensured that liquid level
Remain at setting height.Obviously, spout hole 9 can both be opened on the waterwall 5 of entrance point port position in advance.Certainly
On the premise of receiving terminal port is provided with waterwall 5, it is also possible to which spout hole 9 is arranged on the waterwall of receiving terminal port position
On 5.
Wherein, the catch pit that the water of spilling can be entered first in working pit 11, then be evacuated to outside working pit 11 through water pump.
It should be noted that in order to keep liquid level, in addition to setting spout hole 9 on waterwall 5, it is also an option that in set
Spout hole 9 is set on pipe 1, or directly auxiliary is drawn water with suction pump.It is preferred that the setting of spout hole 9 can ensure that pipeline section enters
Suspended state or floating state are kept after described sleeve pipe 1.
In S5, during pipeline is pushed or pulled into sleeve pipe 1, it can use technology hand disclosed in any prior art
Section.Equally, the end of pipeline is passed through in poling hole threading 1 also based on same technological means in S3.
Wherein, when the interior conduit of sleeve pipe 1 includes many pipeline sections, the pipeline section that will be close to the receiving terminal is first gradually moved to institute
State in sleeve pipe 1, until the pipeline section only has afterbody and stays in outside described sleeve pipe 1, it is now that the pipeline section and another pipeline section is end to end.Its
In, for the pipeline section of steel, the connection between can carrying out pipeline section by the way of welding, and butt welding mouth position are carried out at anti-corrosion
Reason.
In S6, after the equal sleeve pipe 1 of pipeline, in order to ensure that pipeline is finally accurately arranged on support member, can be with
While liquid in exclusion sleeve 1, human assistance is adjusted to the position of pipeline.Obviously, under buoyancy, it is only necessary to
Manually can just realize being accurately positioned for pipeline on a small quantity.Certainly, in an ideal case, after liquid is discharged from sleeve pipe 1, pipeline meeting
Automatic accurate falls in support member, without manually adjusting.Wherein it is possible to emitted the water in sleeve pipe 1 using pump, when
Can also so cause that the water in sleeve pipe 1 flows out naturally by way of opening.
After S6, can select to disassemble waterwall 5.
The steel that the above method is applied to a diameter of 1200mm is regenerated into when laying of waterpipe 2：First of all for being easy to apply
Work, can cut into every 6m by the pipeline section of factory calibration length 12m；Secondly, for above-mentioned recycled water pipeline section, by support member
It is set to 2.5m；Thirdly, in pipeline section laid processes, when the recycled water pipeline section of the 6m has a quarter sleeve pipe 1,
Now start the water filling toward in sleeve pipe 1；Also, when recycled water pipeline section only 1m stay in sleeve pipe 1 it is outer when, by follow-up recycled water pipeline section
Welded with current recycled water pipeline section.
In order to further facilitate pipeline laying, the present embodiment provides a kind of pipeline work platform 10, refers to Fig. 3.From Fig. 3
In it can be seen that, the pipeline work platform 10 be arranged on the entrance point port of sleeve pipe 1 outside, so as to facilitate laying for subsequent pipeline.
Fig. 4 and Fig. 5 is referred to, the pipeline work platform 10 of the present embodiment lays for the interior conduit of sleeve pipe 1, including support
Platform and in the support platform and along setting track be distributed multiple directive wheels to 14；The directive wheel is wrapped to 14
Include the wheel shaft being fixed in the support platform, and a pair of directive wheels on the wheel shaft；The directive wheel is in circle
Mesa-shaped and small head end is oppositely arranged.
The pipeline work platform 10, by directive wheel to 14 support pipelines, so as to when pipeline is moved along setting track
Directive wheel is rolled to 14 directive wheel with the propulsion of pipeline, effectively prevent sliding friction and the outer corrosion-resistant of pipe surface is damaged
It is bad.Further, since directive wheel is oppositely arranged in round table-like and small head end, so that multiple directive wheels can form the recessed of pipeline to 14
Receiving space is fallen into, effectively to prevent pipeline from rolling skew, and ensures that pipeline is moved along setting track.
Wherein, setting track can determine according to the relative position of pipeline work platform 10 and sleeve pipe 1.To regenerate waterpipe
As a example by 2 lay, if pipeline work platform 10 is located at the entrance point port of sleeve pipe 1, and support platform height and sleeve pipe 1
The height correspondence of interior steel bracket 3, then now set the straight path that track is just directed to steel bracket 3.
Additionally, above-mentioned " the small head end of directive wheel " is directed to for round table-like directive wheel, wherein round table-like directive wheel includes
Two bottom surfaces, one end is small head end where the smaller bottom surface of directive wheel, and larger bottom surface is on one point stub end.
In order that the pipeline that directive wheel is adapted to different tube diameters to 14 is obtained, a pair of directive wheels preferably on wheel shaft, therebetween
Away from can adjust.That is, directive wheel can be slided and fixed along wheel shaft.For example, wheel can be directed to by collar being limited to
Some ad-hoc location of wheel shaft.Specifically, after directive wheel slides into ad-hoc location along wheel shaft, axially the two of directive wheel
End is respectively mounted collar, and the collar is locked on wheel shaft, such that it is able to prevent directive wheel from further sliding.When need adjust directive wheel
During position on wheel shaft, then the collar is unloaded.Certainly, in addition to using collar, can also be realized by other structures
Fixation of the directive wheel on wheel shaft.
Wherein, when pipeline work platform 10 is used to lay the larger pipeline of caliber, between can now increasing directive wheel
Away from ensureing that pipeline can reliably be arranged on directive wheel on 14, and stabilization is moved along setting track.Work as pipeline work
When platform 10 is used to lay caliber less pipeline, the now corresponding spacing for reducing directive wheel, to avoid pipeline directly and wheel
Axle comes in contact.
When pipeline its caliber for needing to lay is larger, if the spacing now between directive wheel is too big, may cause
Pipeline is directly contacted with wheel shaft.In view of this, in the present embodiment, the first BOGEY WHEEL is preferably installed on wheel shaft.First load-bearing
Wheel is located between directive wheel described in a pair, so as to can prevent wheel shaft abrasion pipeline whenever.Wherein, first BOGEY WHEEL
