Description
Technical field
The utility model relates to a kind of novel thermal power plant ribbing cooling tower.
Background technology
Cooling tower, as a kind of industrial circulating water cooling infrastructure, is one of important buildings or structures in thermal power plant. Cooling tower is typical towering shell structure, very responsive to wind load. Wind draws role and depends on to come properties of flow, ventilator geometry, ventilator outer surface roughness, ventilator surface features and the impact of contiguous buildings or structures on air-flow on cooling tower. In order to improve the effect of wind load to ventilator housing, the ventilator housing outer surface of being everlasting is along meridian to ribbing. The externally ribbed cooling tower of barrel is called rib tower; The cooling tower of not ribbing of barrel outer surface is called apleuria tower.
According to relevant specification of country, acting on Equivalent Wind Load standard value on cooling tower outer surface can be obtained by calculation of parameter such as fundamental wind pressure, wind pulse, average blast breadth coefficient and height variation coefficient of wind pressures, and wherein average blast breadth coefficient is for apleuria tower with there is rib tower to have bigger difference. About the blast distribution curve that has rib tower, in German Specification (VGB), provide the coefficient in blast distribution Fu Shi series expansion according to prototype tower measured result. Through the blast distribution curve that has rib tower and apleuria tower is contrasted, there is rib tower because surface roughness is larger, can greatly reduce the tower cylinder, pillar, the cyclic group internal force that are caused by blast, increase cooling tower structure reliability.
There are rib tower blast distribution curve and tower tube outer surface roughness value (hR/aR) relevant, high relevant with rib spacing with rib. Have rib tower rib cross section to be generally trapezoidal, domestic specification has been made regulation and suggestion, trapezoidal height h to its sizeRShould get 100mm～200mm, bottom width b should get 250mm, and hypotenuse gradient m should get 0.25.
When armored concrete hyperbola cooling tower cylinder Wall Construction, can adopt mould crawling process, boat scaffold to turn over mold technique or other technique according to actual conditions, barrel template adopts dead-shape compound steel mould, plank sheathing etc., and mounting cylinder wall form adopts the aligning methods such as total powerstation, laser collimator; In the time adopting plumb bob centering, should eliminate wind, vibration etc. to its position influence. In the time of cooling tower ribbing, rib template adopts profiled template, and profiled template quantities is larger than apleuria tower, wastes more. Rib is answered arrangement reinforcing bar, needs strictly to control the perpendicularity of rib in work progress, has therefore greatly increased workload.
In sum, apleuria tower is compared with there being rib tower, and the advantage of apleuria tower is: form work engineering amount is little, and speed of application is fast; Shortcoming is: the tower cylinder less stable that blast effect causes, tower cylinder construction costs is higher. There is the advantage of rib tower to be: can effectively reduce blast effect, increase tower cylinder stability, reduce construction costs; Shortcoming is: form work engineering amount is large, and profiled template waste is more, and the construction period is longer.
At present, domestic cooling tower great majority are apleuria tower, have rib tower quantity to account for smaller, due to problems such as barrel rib difficulty of construction are large, efficiency is low, have made rib tower in Practical Project, be difficult to give full play to its advantage.
