The mounting means of pipe well internal riser is in the prior art:Standpipe erection sequence is from bottom to top by more composition standpipe Pipeline section carry out sequential concatenation, in this way, according to the length of single pipeline section, it is necessary to be respectively provided with pipe level fortune at every layer of building Defeated passage or interlayer set pipe level transport channel, each pipeline section are transported to pipe well, in this way, the vertical and horizontal fortune of pipeline section It is defeated often, there are the problem of standpipe low construction efficiency;Simultaneously as the pipeline section increased newly when docking every time is located at the company of completion The top of nozzle belt, the upper and lower pipeline section in welding position, which aligns, keeps verticality connection difficult to realize, simultaneously because welding position can be with Standpipe and be laid with the change of height and change, be located at small space or during by wall position running into welding position, also exist and stand The problem of pipe welding difficulty is big, welding quality is difficult to ensure that.
The content of the invention
It is directed in the prior art in pipe well internal riser installation process for set forth above, pipeline section transport difficulty is big, pipeline section Between dock the problem of centering difficulty is big, welding difficulty or welding efficiency are low, the present invention provides a kind of installation of pipe well standpipe to apply Work method, the transport number of pipeline section is few in this method, be easy to centering docking between pipeline section, welding region is fixed, easy to control weldering Connect quality and improve welding efficiency.
A kind of pipe well standpipe construction method of installation provided by the invention is solved the problems, such as by following technical essential:One kind pipe Well standpipe construction method of installation, the standpipe that this method is used to be formed by more pipeline section docking is vertically-mounted in pipe well, described vertical Pipe includes N root pipeline sections, and by top to the bottom of standpipe, N root pipeline sections be respectively pipeline section 1, pipeline section 2, pipeline section 3 ..., pipeline section N, this Method includes the following steps that order carries out:
S1, mounting hanger:Main hoist and secondary hoist are installed in pipe well;
S2, lifting pipeline section:Pipeline section 1 is lifted by crane by the bottom of pipe well by main hoist, and makes 1 bottom of pipeline section away from pipe well bottom Height number be more than pipeline section 2 length;
Pipeline section 2 is lifted by crane by the bottom of pipe well using secondary hoist, and makes the upper end tube nozzle of pipeline section 2 and the lower end pipe of pipeline section 1 Mouth butt welding;
The height of the standpipe section of connection has been completed using the lifting of main hoist, pipeline section is lifted using secondary hoist successively 3rd ..., pipeline section N, and each pipeline section is docked in the case of hanging with the bottom of upside standpipe section, it is sequentially completed in standpipe section Connect pipeline section 3 ..., pipeline section N;
In above procedure, pipeline section 3 ..., pipeline section N by pipe well bottom be sent into pipe well, under the lifting of secondary hoist according to Secondary installation, and before pipeline section N completes installation, other pipeline sections often complete docking of the pipeline section below standpipe section, that is, pass through The standpipe section of connection is once completed in the lifting of main hoist so that next pipeline section can under the lifting of secondary hoist with upside The standpipe section for completing connection is vacantly docked;
After pipeline section N completes connection, standpipe is obtained;
And when each pipeline section docks, the pipeline section of pipeline section and lower section above docking location is in vertical state;
S3, carry out fixation of the standpipe in pipe well.
Specifically, as those skilled in the art, according to the height of building and the length of single pipeline section, above N is Any positive integer more than or equal to 1.In the present solution, hanged first by main hoist equivalent to by the pipeline section of standpipe top It is empty to certain altitude, second pipeline section by top to bottom number number is then lifted by crane by secondary hoist, at this time due to being suspended in Height of the pipeline section lower end away from pipe well bottom is more than the length of second pipeline section on main hoist, in this way, second pipeline section and upper end When pipeline section splices, second pipeline section is hanging, in this way, ensureing that first pipeline section and second pipeline section are hanging very well, at this time, utilizes The gravity of each pipeline section, may be such that each pipeline section can keep preferable vertical posture, preferably right when carrying out butt welding, to obtain Interface glacing flatness;Then, after second pipeline section is completed to dock with upper end pipeline section, second pipeline section is also suspended in main hoist On, secondary hoist can lift the 3rd pipeline section, the 4th pipeline section ... by the bottom of piping shaft at this time, be docked at main hoist successively and lift Standpipe section bottom.
In the present solution, being sent into pipe well by the bottom of pipe well due to each pipeline section completes docking and lifting etc., therefore entirely manage , not only can be naturally vertical by each pipeline section of gravity in well in the installation process of vertical duct, it can ensure standpipe connection Align and the position of verticality while standpipe welding is in the downside for being fixed on pipe well, the growth of length will not be spliced with standpipe And change the position of welding point, in this way, it is convenient specific welding region is set in pipe well with obtain preferable activity space into Row manual welding, automatic welding, it is ensured that welding quality and efficiency, such as carry out welding only at building second layer floor pipe well, Avoid significantly personnel's safe operation accident occur, at the same time, compared to the prior art, this programme equivalent to pipeline section splicing be by upper and It is lower and not the prior art from bottom to top, in this way, pipeline section lifting is to use " upside-down method of hull-section construction " sequence of construction, the horizontal transport of pipeline section The first floor of building is only arranged at, avoids the security risk of every layer of horizontal transport of pipeline section significantly so that pipeline section transportation safety, pipe Section vertical transport is only limitted in construction pipe well, and it is small that it influences face, it is ensured that safety, simultaneously as constructed using " upside-down method of hull-section construction ", it is secondary Distance of the hoist upper tube pars infrasegmentalis away from pipe well bottom can be infinitely small, and distance of the pipeline section away from pipe well bottom is slightly larger than on main hoist Length of pipe section to be connected, in this way, when falling accident occurs, compared to existing " upright method of hull section construction ", greatly reduce pipeline section or Standpipe section falls distance, even if dropping, its vertical range is also controllable to only be slightly over the length of a pipeline section, such as According to the height of the relation of existing pipeline section and building storey height, only building first floor, simultaneously as main hoist is whole Do not have to frequently with pipeline section depart from work progress, therefore the pipeline section on main hoist suspends reliability height in midair in itself, in this way, using we Method, will not cause harm of falling greatly very much.
To sum up, using this construction method, not only it is greatly improved standpipe construction quality, it is ensured that standpipe verticality is much smaller than 5L ‰, counterpart glacing flatness is welded between pipeline section within 1/100, whole process is not more than 10mm, while weld appearance is smooth, no overlap Etc. bad phenomenon;Meanwhile this programme is used to shorten pipe well internal riser construction period as 2/3rds of existing construction period.
Preferably, to ensure when each pipeline section docks, the pipeline section of pipeline section and lower section above docking location is in vertically State, may be configured as each pipeline section lifting using vertical lifting.
Further technical solution is:
To obtain preferable manual welding welding operating space or setting automatic welding device in pipe well specific location, to realize Pipeline section high quality, high efficiency docking, in step s 2, when docked with upper end pipeline section, docking location is respectively positioned on each pipeline section Same position in pipe well.
In step s 2, when whole pipeline section docking is not completed within a continuous work cycle, by operating main hoist, The lower end for having connected standpipe section is discharged to managed bottom and is supported, is lifted in next continuous work cycle by main hoist After having connected standpipe section, then carry out the docking of follow-up pipeline section.Using this programme, the continuous work cycle can be regarded as one day or One construction shift, such as constructed when finishing next on the same day, can discharge the lower end of the whole standpipe section to connecting to pipe Bottom, as on platform, main hoist is not subjected to standpipe section pulling force at first floor pipe well, standpipe section is attached on pipe well wall, nothing Personnel are needed to keep an eye on, it is ensured that pipe well internal riser section safety, in this scheme, the decentralization of standpipe section is apart from short, according to existing single pipeline section Length, release is high from level to level, i.e., this method is easy for construction, while its pull-up is continued to apply by second day by main hoist again Work, greatly improves the security in pipe well standpipe work progress.
