(2), the funnel under the depositing dust pipe is winched to the installation site;
(3), conduit saddle is installed and is leaked seat, it is integrally welded to leak seat and conduit saddle;
(4), install and be responsible for: according to actual conditions, from inside outwards install; The depositing dust pipe is divided into some joints, and every joint length is 2-3m, and single-unit weight is no more than the electric block rated load weight, and the depositing dust pipe is put into assigned address from the hole for hoist lifting, welds between straightening then, the tube and tube;
(5), depositing dust pipe top perforate: the top perforate of depositing dust pipe is connected with airduct, airduct is winched to depositing dust pipe top, draw from the airduct center and to throw to the depositing dust pipe, then according to the perforate on the depositing dust pipe of airduct size, airduct and the welding of depositing dust pipe should be waited for that airduct is connected with top equipment and carry out after finishing again;
(6), depositing dust pipe bottom perforate: the bottom perforate of depositing dust pipe is welded with leaking seat, should be in advance with being responsible for and leaking the seat outside weldings, then according to the perforate of funnel size for preventing being responsible for distortion before the perforate, after perforate is finished, with jack funnel is sling, weld with leaking seat, and the inside and outside is filled weld seam;
(7), the stiffened panel on the depositing dust pipe is installed, agglomerating chamber's depositing dust pipe installs.
And, two electric blocks are installed on the described I-beam track.
Advantage of the present invention and beneficial effect are:
1, this agglomerating chamber depositing dust pipe construction method adopts service sleeve installation I-shaped beam orbit on the beams of concrete of agglomerating chamber's bottom surface corresponding above the depositing dust pipe, adorns an electric block at the I-beam track.With electric block lifting depositing dust pipe, saved large-scale hoisting machinery, rationally utilized installing space, reduced installation cost, reduced the potential safety hazard of construction, guaranteed the construction period of engineering.
2, this agglomerating chamber depositing dust pipe construction method can adopt two electric blocks are installed on the I-beam track, and the depositing dust pipe is installed in segmentation, shortens the engineering time, improves efficiency of construction, guarantees the construction continuity.
3, construction method of the present invention is simple, need not large-scale hoisting machinery, effectively shortened the depositing dust pipe set-up time, and improved efficiency of construction, reduced construction cost, improved construction quality, be a kind of safe and reliable agglomerating chamber's depositing dust pipe construction method.
