Abstract

The invention discloses large-span overhead pipeline sliding installation technology which comprises an overhead pipeline truss. The technology is characterized by comprising the following installation steps: a) making a new bracket and a temporary bracket; b) providing multiple sections of pipelines; c) installing a horizontal pipeline spanning over a factory protection river and an over-railway section; and d) installing vertical sections of pipelines on the two sides of the horizontal pipeline. By the large-span overhead pipeline sliding installation method disclosed by the invention, pipelines can be hoisted in place successfully when the pipelines cannot be hoisted in place conventionally by a crane due to the restriction of a narrow field and other objective conditions, the construction safety and installation quality are guaranteed, and the installation construction expenses is reduced greatly.

Description

The long span over head slide installation method

Technical field

The present invention relates to a kind of long span over head slide installation method.

Background technique

Water pipe or tracheal tube are buried under the ground usually.These pipelines are embedded in about 6 meters to 12 meters degree of depth place traditionally.Yet, water pipe or tracheal tube can't be embedded in the location usually.For example, water pipe or tracheal tube can not be embedded in the zone of having imbedded many pipelines under the river,, perhaps pipeline be embedded under the busy traffic route, under the railway.

Baosteel shoal area mating power main engineering comprises in one and presses nitrogen pipeline, caliber D426 * 9, pressure 0.7MPa.The whole construction pipeline is very long, and it is very big to Weiyi Road railway division piping erection difficulty of construction that wherein nitrogen pipeline is crossed over latitude ten one road Hu Chang rivers.In both sides, Hu Chang river a support is arranged respectively, 29 meters of set spacings (being original support truss), 9.2 meters of pipe end absolute altitudes, 35.8 meters of cross a river pipeline section total lengths, the heavily about 3.5t of pipeline section.This segment pipe centre distance latitude ten one tunnel about 39 meters, distance is far away, and crosses over original piping lane, the construction and installation difficulty.Latitude ten one road Hu Chang rivers are between Weiyi Road, complete is Department of Transportation's railway, have 12 railroad tracks herein, train running is very frequent, if this segment pipe is constructed routinely and need be taken the production railway for a long time, and railway idle time can't satisfy the construction needs far away, crane can't enter the scene and carry out lifting operation.

Therefore known directly exists above-mentioned all inconvenience and problem with crane with the pipeline lifting method.

Summary of the invention

Purpose of the present invention, be to propose a kind of because of the place narrow or other objective condition difficulties can not be directly with the long span over head slide installation method of crane lifting pipeline.

For achieving the above object, technical solution of the present invention is:

A kind of long span over head slippage mounting technique comprises an aerial pipeline truss, it is characterized in that comprising following installation steps:

A) make new support and falsework

Several new supports of welding production, falsework and an interim portal frame on described aerial pipeline truss, described new support, falsework and interim portal frame are formed a support system, so that the slippage on described support system of described pipeline; Wherein new support and falsework comprise one " door " glyph framework, two stent strut lower ends of described " door " glyph framework are welded on described aerial pipeline truss both sides, and being the miter angle direction with a support diagonal brace and stent strut is welded on the described aerial pipeline truss, the top of the set cap of described " door " glyph framework is provided with the rubber roll mounting, in described rubber roll mounting, be provided with rubber roll, and described rubber roll mounting both sides are provided with the high baffle plate of 200mm, to prevent that pipeline from coming off in slipping, described rubber roll mounting apical side height exceeds about 50mm than described " door " glyph framework height simultaneously, can remove falsework in described pipeline slippage back in place thus, roller, and corresponding conduit saddle is installed; Described falsework is interspersed to be arranged between the newly-built support, forms the about 5m of each set spacing;

B) provide the plurality of sections pipeline

At the described pipeline preceding brushing paint of putting on the shelf, reduce the damage to paint during slippage, to broken parts touch-up paint in addition, described pipeline lifts into about 20 meters one section at installation on ground after finishing as far as possible, heavily about 2 tons of every segment pipe, and at an end of described pipeline welding hanger;

C) horizontal pipe of striding the Hu Chang river and striding the railway division is installed

Lift respectively with 120 tons of mobile cranes and 80 tons of mobile cranes and to stride railway and cross a river segment pipe, after pipeline being sling with crane, pipeline is in place inward, and send inward as much as possible, pipeline is ridden on the roller of newly-built and falsework, then wire rope is fastened on the pipeline hanger, use the zipper calabash movement pipeline, this moment, crane followed up as much as possible, until loose hook; Continue slippage and reserve the position of second section pipe, and then second section pipe of hoisting slide, second section is continued inward slippage to spot welding after fixing with first section group, carries out the 3rd section, the 4th section pipe slippage successively and installs, until finishing;

D) the vertical segment pipe of the described horizontal pipe of installation both sides

With described interim portal frame, be equipped with the 3t zipper calabash the vertical segment pipe in both sides is installed, hang the pipeline hanger, cut described vertical pipeline according to the figure paper length with the top zipper calabash, use zipper calabash temporary fixed then, treat the two ends pipeline in place after again welding fix.

After adopting technique scheme, long span over head slide installation method of the present invention has the following advantages:

1, can can't directly utilize routinely under the crane lifting situation in place the smooth hoisted in position of pipeline in and other objective condition restrictions narrow because of the place;

2, guarantee construction safety and installation quality;

3, significantly reduce the installation expense.
