Abstract
The present invention relates to pipe installation method, particularly relate to the installation method of high vacant duct vertical section.A kind of high-altitude big-diameter pipeline vertical section pipe installation method, it comprises: step one, and support platform is built; Step 2, lifts the pipeline of described vertical section with truck crane, unclamp truck crane suspension hook after Pipe installing.The present invention can accelerate the duration of high-altitude Pipe installing, meets the requirement of owner to the duration.
Description
Technical field
The present invention relates to pipe installation method, particularly relate to the installation method of high vacant duct vertical section.
Background technology
Along with the high speed development of steel industry, the traditional industrial structure of each steel plant can not be met the need of market, the project reconstruction such as increasing steel industry is recombinated to self structure, technological transformation, enlarging.The interface method of the new and old pipeline of its high and medium Large Diameter Pipeline becomes the heavy difficult point of transformation project.In extra-thick slab casting machine project, the new and old pipeline of one-time dedusting pipeline carries out interface when installing: vertical pipe (φ 2620) the tube hub absolute altitude of one-time dedusting pipeline modification is from from+7.5m--+49.8m, and single pipe weighs 32.7t.Should install from bottom to top according to normal working procedure, and owner gives the time very section with construction party at present, the duration is very nervous, and existing installation method cannot meet nowadays urgent construction period.
Summary of the invention
The present invention is intended to address the aforementioned drawbacks, and provides a kind of high-altitude big-diameter pipeline vertical section pipe installation method.The present invention can accelerate the duration of high-altitude Pipe installing, meets the requirement of owner to the duration.
For solving the problem, must formulate a kind of rationally, effective method to lift this section of vertical pipe, the emphasis will considered before lifting is that pipeline will carry out support platform in a pre-installation, is drawn by girder and collapse after preventing from installing; Prevent pipeline hoisting point position unbalance stress from causing tube wall drawing crack when also will consider lifting pipeline simultaneously, must on the duct wall of welding hanger position, weld reinforcing sleeve and adopt T-shaped hanger.
A kind of high-altitude big-diameter pipeline vertical section pipe installation method, it comprises:
Step one, support platform is built;
Step 2, lifts the pipeline of described vertical section with truck crane, unclamp truck crane suspension hook after Pipe installing.
Described high-altitude big-diameter pipeline vertical section pipe installation method, described step one comprises: the structural steel beam of pipe support platform is welded stay pipe bearing, and bearing adopts channel-section steel to make diagonal brace, and platform adopts steel plate; On pipeline, weld stay pipe base support platform as pipeline support point, pipeline support platform adopts tube wall reinforcement form as support platform simultaneously; Often organize pipeline welding and be no less than three group platforms;
Described high-altitude big-diameter pipeline vertical section pipe installation method, described step 2 comprises: after Standing position of a crane is good, lifting vertical section pipeline, and pipeline butt is rear welded pipe line well, after counterpart, simultaneously crane can not loose hook for welded pipe line, etc. upper interface positioning welding complete after pipeline bottom is supported.The spiral welded pipe that supporting pipeline adopts.Prevent pipe walls support place unbalance stress from tube wall drawing crack being adopted in support platform position, pipe portion tube wall to thicken and strengthen intensity measure.Install supporting pipeline and adopt crane lifting supporting pipeline, pipeline should be welded on relevant position by welding cat ladder in advance with welding of support platform.
Described high-altitude big-diameter pipeline vertical section pipe installation method, in described step 2, stay pipe has welded the not loose hook of front whole process crane, and after strutting means completes, loose hook completes vertical section Pipe installing task.
Support platform has been welded by the present invention before lifting straight length, is first installed by stay pipe in hoisting process, and then loose truck crane suspension hook, otherwise the gravity of vertical tube will can not get supporting and the roof girder that crushes.So greatly accelerate the installation of pipeline, meet the requirement of owner to the duration.
Detailed description of the invention
A kind of high-altitude of the present invention big-diameter pipeline vertical section pipe installation method, it comprises:
Step one, support platform is built; The structural steel beam of pipe support platform is welded stay pipe bearing, and bearing adopts channel-section steel, and [16 make diagonal brace, and platform adopts the steel plate of 500mm*500mm*10mm; On pipeline, weld stay pipe base support platform as pipeline support point, pipeline support platform adopts tube wall reinforcement form as support platform simultaneously; Often organize pipeline welding and be no less than three group platforms.
Step 2, lifts the pipeline of described vertical section with truck crane, unclamp truck crane suspension hook after Pipe installing.After 200t Standing position of a crane is good, lifting vertical section pipeline ,+49.8m locate pipeline butt well after welded pipe line, after counterpart, crane can not loose hook simultaneously for welded pipe line, etc. upper interface positioning welding complete after pipeline bottom is supported.Supporting pipeline adopts the spiral welded pipe of φ 273*8.Prevent pipe walls support place unbalance stress from tube wall drawing crack being adopted in support platform position, pipe portion tube wall to thicken and strengthen intensity measure.Supporting pipeline being installed and adopting 25t crane lifting supporting pipeline, relevant position should be welded on by welding cat ladder in advance for convenience of supporting pipeline with welding of support platform.Stay pipe has welded the not loose hook of front whole process 200t crane.After strutting means completes, loose hook completes vertical section Pipe installing task.For further interface work provides fast interface to create good condition.
