Mounting hole (20), by bottom plate (19) binding on blower foundation bottom reinforcement bars, the mounting ring template in the endoporus of bottom plate (1)
(10), ring moulds plate (10) is placed on the bottom reinforcement bars of blower foundation；
Three), positioning disk is installed：
Cross-arm (4), vertical load (5) are lain in a horizontal plane on the top of ring moulds plate (10), steel wire rope or shackle are hung on partition board (3)
On hook on hole (16) in, positioning disk (1) is hung at cross-arm (4), on vertical load (5), makes the center line and ring moulds of positioning disk (1)
The center line of plate (10) corresponds to consistent；
Four), support construction is installed：
It is corresponding that four foundation is flatly set to support 8 in orthogonal four orientation of ring moulds plate (10), by each bottom bracing (8) with
The bottom reinforcement bars banding fixed of blower foundation, by four vertical braces (6) be respectively perpendicular with corresponding cross-arm (4) or vertical load (5), bottom
Support (8) is mutually welded, and every group of two diagonal braces (7) are mutually welded two-by-two with corresponding cross-arm (4), vertical load (5), bottom bracing (8) across；
Five), guide pile, duct pipe are installed；
Each positioning seat is corresponded to and is mounted on bottom plate (19) in uniform way positioned at the outer circumference portion circle of position week of ring moulds plate (10), it is each fixed to make
The center line of position stake (12) mutually corresponds unanimously with the center line of the corresponding location hole (2) on positioning disk (1), by each base disk
(14) it is mutually fixed with fastening bolt (9) with the bottom plate (19) on blower foundation respectively, then, by each duct pipe (11) from top to bottom
Ground passes through location hole (2) and is inserted into the annular groove (15) on guide pile (12) periphery, completes the installation of each duct pipe (11), then into
The binding of sector-style machine basis upper reinforcement and the installation of exterior sheathing using the concrete of conventional method cast blower foundation, are treated
After the intensity of concrete reaches 70%, positioning disk (1) and ring moulds plate (10) are removed, by each positioning seat, duct pipe (11), cross-arm
(4), load (5), bottom bracing (8), vertical brace (6) diagonal brace (7) and bottom plate (19) are indulged.
