For addressing the above problem, the utility model adopts following technical scheme:
The utility model is a kind of with four times centrifuges thin-wall reinforced concrete pole towers of tower, described shaft tower is followed successively by first section, second section, the 3rd section, the 4th section and the 5th section from the top to the bottom, the section with the section between the employing flange be connected, described every section shaft tower is the single-column thin wall centrifugal steel concrete pipe structure, the tower wall is a low-alloy carbon structure head tower wall, the thick centrifugal concrete layer of compound 35-45mm in the wall.
First section described in the utility model, second section and the 3rd section is provided with cross-arm, and described cross-arm is the suspending bars angle steel cross-arm of symmetry, is connected with bolt between cross-arm and the tower body.First section is provided with 3 road cross-arms, and second and the 3rd section is respectively arranged with 2 road cross-arms, shaft tower from the top and under first to fourth cross-arm be respectively 220Kv double circuit line cross-arm, below three cross-arms be 110Kv double circuit line cross-arm.
Each section described in the utility model junction is provided with the zigzag reinforced pipe, and on ring wall the multiple spot rivet welding is set evenly.
Described in the utility model with tower four times on same shaft tower, to set up two circuits, be the 200Kv circuit above, be the 110Kv circuit below.Described tower wall steel plate is thinner; Steel plate thickness is 6mm-14mm, the inner evenly compound layer concrete of steel plate, concrete thickness 35mm-45mm.
The utility model is with four times centrifuges thin-wall reinforced concrete pole towers of tower, and described with four times centrifuges thin-wall reinforced concrete pole towers employings of tower single-column thin wall centrifugal steel concrete pipe structure, cross-arm adopts suspending bars angle steel cross-arm.Main material adopts the low-alloy structural carbon steel, and the thick concrete of inner centrifugal 35-45mm has made full use of the tensile strength and the concrete crushing strength of steel, and the characteristic of the two is fully utilized.Overcome the shortcoming that steel pipe pole rigidity is poor, amount of deflection is big.Overcome the shortcoming of concrete shaft tower external crack simultaneously, combination property greatly improves.Concrete every performance indications have improved a new height, and the compressive strength of concrete in test and production all is controlled at more than the 45MPa.
The utility model body of rod amount of deflection is little, the rigidity height, and floor space is little, and bearing capacity is big and price is low.
The utility model is used for the power construction in narrow location, circuit corridor with four times centrifuges thin-wall reinforced concrete pole towers of tower, and construction is simple, convenient.
The utility model is rational in infrastructure, and selection is suitable.Can satisfactorily finish tasks such as setting up of electric power.The utility model enlarges the usage space with four times centrifuges thin-wall reinforced concrete pole towers of tower more, brings bigger convenience to power construction.
The utility model is little with four times centrifuges thin-wall reinforced concrete pole towers of tower amount of deflection, and rigidity is big, and floor space is little, and site operation is convenient and swift.Be applied to very narrow location, circuit corridor.Having reduced limitation, obtained user's favorable comment, is four times centrifuges thin-wall reinforced concrete pole towers of a kind of comparatively desirable same tower.
Application of the present utility model can be alleviated the trend of power tense, will produce immeasurable social benefit for the development of utilities such as all trades and professions.It is a kind of desirable novel product.Not only can obtain considerable economic, the more important thing is to have produced higher social benefit.
