Description
Technical field
The present invention relates to a kind of supporting construction of the indirect dry cooling tower in thermal power plant, more particularly to one kind is suitable for super
The supporting construction for the indirect dry cooling tower with high air inlet that high air cooling heat radiator is radiated.
Background technology
Because 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, and these factors directly results in sky
The height more and more higher of cold heat sink.In thermal power plant, the Concrete Cooling Water Tower built is mainly by annular concrete
Basis, stub, X-shaped intersects post and tower forms, and the height of tower diameter and X-shaped intersection post determines the intake of cooling tower；
Post is intersected by annular concrete basis, stub, X-shaped and tower lower ring constitutes the supporting construction 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 construction of air inlet
X-shaped intersect the height of post and increase therewith, this just directly results in section increase that X-shaped intersects post, make the choke face of cooling tower
Product increase, has had influence on the intake of cooling tower and the thermal performance of air cooling system, and increase the construction costs of supporting construction.
The content of the invention
The invention provides a kind of supporting construction of high air inlet indirect dry cooling tower, solves and is hindered caused by high air inlet
Wind area increases and the technical problem of construction costs increase.
The present invention is that solve above technical problem by the following technical programs：
A kind of supporting construction of high air inlet indirect dry cooling tower, including annular concrete foundation base, in annular concrete foundation base
On be provided with equal intervals radian intersect post support pier（2）, respectively it is provided with left bank on each intersection post support pier and mixes
Native pillar and right bank concrete pillar are coagulated, 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；It is each to intersect post
Left bank concrete pillar on support pier intersects the adjacent right bank coagulation intersected on post support pier on the left of post support pier with this
Native pillar intersects a post support pier left side formed with lower-left crosspoint, each left bank concrete pillar intersected on post support pier with this
The adjacent right bank concrete pillar intersected on post support pier in side interval is formed with upper left crosspoint；It is each to intersect on post support pier
Right bank concrete pillar intersect the adjacent left bank concrete pillar shape intersected on post support pier on the right side of post support pier with this
Into there is bottom right crosspoint, each right bank concrete pillar intersected on post support pier intersects interval phase on the right side of post support pier with this
Left bank concrete pillar on neighbour's intersection post support pier is formed with upper right crosspoint；Adjacent intersection on the left of the intersection post support pier
Right bank concrete pillar on post support pier intersects with this and adjacent on the right side of post support pier intersect the left bank on post support pier and mix
Native pillar is coagulated formed with middle overcrossing point.
Each right bank concrete pillar intersected on post support pier is set at equal intervals, each left side intersected on post 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 construction costs, is reduced
The wind resistance area of tower.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
The present invention is described in detail below in conjunction with the accompanying drawings：
A kind of supporting construction of high air inlet indirect dry cooling tower, including annular concrete foundation base 1, in annular concrete foundation base
It is provided with equal intervals on 1 radian and intersects post support pier 2, being respectively provided with left bank on each intersection post support pier 2 mixes
Native pillar 3 and right bank concrete pillar 4 are coagulated, left bank concrete pillar 3 and right bank concrete pillar 4 are V-shaped settings
, tower annular girder 5 is provided between the top of left bank concrete pillar 3 and the top of right bank concrete pillar 4；Often
The individual left bank concrete pillar 3 intersected on post support pier 2 intersects adjacent on the left of post support pier 2 intersect on post support pier 8 with this
Right bank concrete pillar formed with lower-left crosspoint 6, each left bank concrete pillar 3 intersected on post support pier 2 with
The adjacent right bank concrete pillar intersected on post support pier 9 in the left side of intersection post support pier 2 interval is formed with upper left crosspoint
7；Each right bank concrete pillar 4 intersected on post support pier 2 intersects with this and adjacent on the right side of post support pier 2 intersects post support pier
Left bank concrete pillar on 10 is formed with bottom right crosspoint 11, each right bank concrete branch intersected on post support pier 2
Post 4 intersects the right side of post support pier 2 with this and is spaced the adjacent left bank concrete pillar intersected on post support pier 12 formed with upper right
Crosspoint 13；The adjacent right bank concrete pillar intersected on post support pier 8 intersects post branch with this on the left of the intersection post support pier
The left bank concrete pillar on the right side of pier on adjacent intersection post support pier 10 is supportted formed with middle overcrossing point 14.
Each right bank concrete pillar intersected on post support pier 2 is set at equal intervals, each to intersect on post support pier 2
Left bank concrete pillar is set at equal intervals.The air intake open height of double cross crutch cooling tower is up to 40 meters or so, with entering
The further raising in air port, an intersection point in X-shaped support column become 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 post Pin numbers.
Using finite element analysis software, the high air inlet dual crossing post 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 post.
