The diameter of described pillar deep water section is less than the diameter of pillar shallow water section, and changeover portion is reducer union, and pillar shallow water section and pillar deep water section are connected as one by changeover portion.
The water sucking mouth of described pillar deep water section is provided with filter screen, and this filter screen adopts the form of structure of round steel right-angled intersection.
The inwall of described pillar is fixed with the chemical feed pipe of an anti-marine growth, this chemical feed pipe extends to bottom pillar from pillar top flange, and chemical feed pipe end is circulus, for even release medicine.
The upper end of described pillar shallow water section exceeds deck 500mm.
The below of described companion flange arranges uniform several bearing ribs, and bearing rib is connected with companion flange and pillar shallow water section respectively.
Beneficial effect of the present invention: the present invention is owing to adopting technique scheme, it is when fetching water, only need assigned address sea water pump pillar being extended to deep water, and the underwater penetration of sea water pump meets normal submergence, not only solve in existing water-supply method need the underwater penetration of sea water pump and pillar all to need to extend to sea level below 100m and run into the type selecting to sea water pump, installation, a later stage working service difficult problem; And because the function of pump pillar deep water section is only drainage, its inside need not arrange sea water pump, and diameter is less than shallow water section diameter, therefore, has saved a large amount of steel than latus rectum pillar; Achieve sea water pump conveniently to lift and keep in repair.
