The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: the double-deck stretch-draw sleeve pipe of the ultra-fine long steel strand of a kind of large span preparation method may further comprise the steps:
One) double-deck at the construction field (site) stretch-draw sleeve design installation site under upper edge, ground span direction arrange a plurality of supports;
Two) all supports of levelling are in the same horizontal plane their Support Position, and the centre of support line under their marked go out to be positioned at double-deck stretch-draw sleeve design installation site;
Three) centre of support first outer tube of line layout and the spot welding that mark in advance in left end support upper edge are fixed; Penetrate in first outer tube managing in first then; And the right-hand member of pipe in first is stretched out outside the right-hand member of first outer tube; In the both ends of first outer tube, support ring flat-plate a, and interior pipe support ring flat-plate a is welded on first outer tube according to pipe in the design attitude embedding;
Four) continue to arrange second along centre of support line direction in pipe, manage in second and is supported on the support through cushion block, left end with first in the right-hand member counterpart of managing weld;
Then second outer tube sleeve managed in second, and the right-hand member of pipe in second is stretched out outside the right-hand member of second outer tube;
With the right-hand member counterpart spot welding of left end and first outer tube of second outer tube, adjust first outer tube and second outer tube, make their levels, and coincide with the centre of support line;
Then the left end of second outer tube and the right-hand member counterpart of first outer tube are welded, last in the right part of second outer tube is embedded in, the pipe supported ring flat-plate b, and accomplishes the welding of interior pipe support ring flat-plate b and second outer tube;
Five) repeating step four), up to the welding of accomplishing whole double-deck stretch-draw sleeve pipe;
Six) levelness and the straightness accuracy of whole double-deck stretch-draw sleeve pipe of measurement after confirming to meet design requirement, are accomplished anticorrosive coating.
Advantage and good effect that the present invention has are: adopt the whole group of field ground to, welding, corrosion-resistant processing and fabricating method, production location is over against the installation site of double-deck stretch-draw sleeve pipe, begins assembly unit from an end of double-deck stretch-draw sleeve pipe; Inner and outer pipe is installed synchronously; Be easy to guarantee construction quality, be easy to guarantee safe construction, for subsequent members integral hoisting, steel strand pass through and steel strand tension provides advantage; And construction cost is low; Short construction period, construction risk is low, remarkable in economical benefits.
