Description
Technical field
The present invention relates to a kind of supporting structure of the indirect dry cooling tower in thermal power plant, more particularly to one kind is suitable for super
The supporting structure for the indirect dry cooling tower with high air inlet that high air cooling heat radiator radiates.
Background technology
Since natural conditions restriction and Urbanization Construction are accelerated, the construction soil for Plant project tends to be nervous,
It is required that cooling system occupation of land in thermal power plant is less and less, and generating set is increasing, these factors directly results in sky
The height of cold heat sink is higher and higher.In thermal power plant, the Concrete Cooling Water Tower built is mainly by annular concrete
Basis, stub, X-shaped intersects column and tower forms, and the height of tower diameter and X-shaped intersection column determines the intake of cooling tower；
Column is intersected by annular concrete basis, stub, X-shaped and tower lower ring constitutes the supporting structure of indirect dry cooling tower, in the branch
The outer ring of support structure is disposed with air cooling heat radiator, with increasing for air cooling heat radiator, it is desirable to as in the supporting structure of air inlet
X-shaped intersect the height of column and increase therewith, this just directly results in section increase that X-shaped intersects column, make the choke face of cooling tower
Product increase, has influenced the intake of cooling tower and the thermal performance of air cooling system, and increase the project cost of supporting structure.
The content of the invention
The present invention provides a kind of supporting structure of high air inlet indirect dry cooling tower, solves resistance caused by high air inlet
Wind area increases and the technical problem of project cost increase.
The present invention is to solve above technical problem by the following technical programs：
A kind of supporting structure of high air inlet indirect dry cooling tower, including annular concrete foundation base, in annular concrete base
It is provided with equal intervals on plinth seat radian and intersects column support pier（2）, "Left"-deviationist is respectively provided with each intersection column support pier
Oblique concrete pillar and right bank concrete pillar, left bank concrete pillar and right bank concrete pillar are V-shaped settings
, tower annular girder is provided between the top of left bank concrete pillar and the top of right bank concrete pillar；Each
The left bank concrete pillar intersected on column support pier intersects the adjacent Right deviation intersected on column support pier on the left of column support pier with this
Oblique concrete pillar intersects column branch formed with lower-left crosspoint, each left bank concrete pillar intersected on column support pier with this
The adjacent right bank concrete pillar intersected on column support pier in interval on the left of pier is supportted formed with upper left crosspoint；It is each to intersect column branch
Right bank concrete pillar on support pier intersects the adjacent left bank concrete intersected on column support pier on the right side of column support pier with this
Pillar intersects on the right side of column support pier formed with bottom right crosspoint, each right bank concrete pillar intersected on column support pier with this
The left bank concrete pillar on adjacent intersection column support pier is spaced formed with upper right crosspoint；Phase on the left of the intersection column support pier
The right bank concrete pillar that neighbour is intersected on column support pier intersects the adjacent left side intersected on column support pier on the right side of column support pier with this
Concrete pillar is tilted formed with middle overcrossing point.
Each right bank concrete pillar intersected on column support pier is set at equal intervals, each left side intersected on column support pier
Concrete pillar is tilted to set at equal intervals.
Each undercrossing point is provided in same level, and each overcrossing point is provided in another same level
's.
The present invention reduces the computational length of support column by the way that an intersection point in X-shaped support column is changed into two intersection points,
In the case where meeting the requirement of specification slenderness ratio and axial compression ratio, the area of section of support column is reduced, reduces project cost, is reduced
The wind resistance area of tower.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
Embodiment
The present invention is described in detail below in conjunction with the accompanying drawings：
A kind of supporting structure of high air inlet indirect dry cooling tower, including annular concrete foundation base 1, in annular concrete base
It is provided with equal intervals on plinth seat 1 radian and intersects column support pier 2, "Left"-deviationist is respectively provided with each intersection column support pier 2
Oblique concrete pillar 3 and right bank concrete pillar 4, left bank concrete pillar 3 are V-shaped with right bank concrete pillar 4
Set, tower annular girder is provided between the top of left bank concrete pillar 3 and the top of right bank concrete pillar 4
5；Each left bank concrete pillar 3 intersected on column support pier 2 intersects with this and adjacent on the left of column support pier 2 intersects column support pier
Right bank concrete pillar on 8 is formed with lower-left crosspoint 6, each left bank concrete pillar 3 intersected on column support pier 2
Intersect the adjacent right bank concrete pillar intersected on column support pier 9 in the left side of column support pier 2 interval with this formed with upper left to intersect
Point 7；Each right bank concrete pillar 4 intersected on column support pier 2 intersects the adjacent column that intersects in the right side of column support pier 2 with this and supports
Left bank concrete pillar on pier 10 is formed with bottom right crosspoint 11, each right bank concrete intersected on column support pier 2
Pillar 4 intersects the right side of column support pier 2 with this and is spaced the adjacent left bank concrete pillar intersected on column support pier 12 formed with the right side
Overcrossing point 13；The adjacent right bank concrete pillar intersected on column support pier 8 intersects column with this on the left of the intersection column support pier
The adjacent left bank concrete pillar intersected on column support pier 10 is formed with middle overcrossing point 14 on the right side of support pier.
Each right bank concrete pillar intersected on column support pier 2 is set at equal intervals, each to intersect on column support pier 2
Left bank concrete pillar is set at equal intervals.The inlet air open height of double cross crutch cooling tower up to 40 meters or so, with into
Air port further improves, and in X-shaped support column a intersection point becomes two or more intersection point.
Double cross crutch forms a plane with mast axis overcrossing point, i.e. all overcrossing points of double cross crutch are at one
In plane, the intersecting angle of two planes where adjacent two crosspoint depends on the diameter of air cooling tower and intersects column Pin numbers.
Using finite element analysis software, the high air inlet dual crossing column indirect cool tower of ultra-large type is carried out structure overall static(al),
Kinematic analysis and the lower cooling tower nonlinear overall stability analysis of fluctuating wind effect, and carried out pair with single cross crutch cooling tower
Than, the results showed that dual crossing column dimension section is smaller, and cost is lower, and demonstrates to high air inlet ultra-large type indirect cool tower using double
It is feasible to intersect column.
