Vertical shaft 12 and tower 2 are entreated, theodolite 11 is equipped in the top center of Central Shaft 12, is surrounded by the top of Central Shaft 12
Four are shaken coil holder 10, and the top of theodolite 11 is equipped with center and hangs box 8, and center, which is hung, is equipped with gage 1 below box 8, the four of tower 2
It is set on peripheral wall there are four snatch block 1, is equipped with snatch block two on 12 direction of Central Shaft in the lower section of snatch block 1
4, center hangs box 8 and passes through snatch block 1 and snatch block 24 by drawstring 5, and the other end, which ties up to, to be shaken on coil holder 10, in center
Hanging between the construction formwork 13 at 2 top of box 8 and tower has gage 27.
Further, jack 3 in tune is additionally provided on drawstring 5, jack 3 is located at the top of snatch block 24 in tune.
Further, snatch block 1 is connected on the built-in fitting of 2 inner wall of tower.
A kind of application method of the measuring device for cooling tower tower radius, the method step are as follows: one, pass through longitude and latitude
Instrument is accurately located at the center of Central Shaft 12；Two, by adjusting the length of jack 3 in different tune, guarantee that box 8 is hung in center
It is placed exactly in the surface of theodolite 11；Three, the absolute altitude that box 8 is hung in center can be measured by gage 1；It four, can by gage 27
It measures center and hangs the distance between box 8 and construction formwork 13；Five, theoretical value and actual value can be calculated to obtain by Pythagorean theorem, i.e.,
It can compare, it is ensured that construction error is in critical field.
In the present embodiment, construction scale is 1 × 350MW Thermal generation unit, and it is naturally logical to be equipped with 1 6000m2 hyperbola
Cool water tower.The cooling tower is located at plant area, face, northeast, tower Center Building coordinate A=4045m, B=2169m, and ± 0.00m is equivalent to
Absolute elevation 559.70m.Cooling tower herringbone column diameter 650mm, plagioclase 8.747m, single column total 48 is to (96), main reinforcement lower end
Anchor into buttress 1.5m, upper end anchors into ring beam 2m, concrete parameters C40W8F150.Absolute altitude 7.80m in face in barrel air inlet, half
Diameter 44944mm, thickness 700mm；Annular bracket together with being respectively equipped at 8.34m with 11.55m absolute altitude, barrel is reinforced concrete
Native cast-in-place structural, concrete parameters C40W8F150；Absolute altitude 89.928m in face in throat, middle radius surface 25522mm, spout elevation
120.00m, diameter 55128mm, barrel maximum gauge 700mm, minimum 180mm.Herringbone column and buttress amount of concrete are about
281m3, the 1st ~ 4 board concrete amount of barrel about 941m3 respectively.
The measurement control work of cooling tower tower construction mainly has radius control, high process control and settlement observation, and climbs
Terraced dark bolt installation control.Corresponding measurement control point should be set before construction by specifications of surveys requirement, center control point is preferably located at
It has constructed on the Central Shaft top surface finished, has been convenient for barrel lower stage direct measuring tape Control Radius；Vertical control point may be provided in
On mounted vertical transport equipment pylon, it is convenient for upward measuring tape pilot measurement；Settlement observation control point should then be arranged in sedimentation and see
Near mark, consolidated with set-point ground, be not easy it is disturbed and convenient for being observed principle；Ladder dark bolt installation control point setting exists
