Abstract

The utility model relates to the field of tower reinforcement, in particular to a corrosion protection device for a power transmission line tower foundation. A tower is placed underground through concrete; a plurality of main ribs are arranged in the tower along the length direction of the tower; outer stirrups are arranged at the periphery of the main ribs at equal intervals to form a reinforcement cage; the part of the tower, which is buried underground, is welded with aluminum-magnesium alloy rings at equal intervals. A reinforcement protection effect for steel ribs is achieved through leading corrosion of large-activity alloy; because of the equal-interval arrangement, the uniformity in corrosion is guaranteed, the long-term problems of operation and maintenance are solved, the steel ribs are effectively protected from being corroded, and the improvement cost is low and the effect is obvious.

Description

A kind of pole and tower foundation anti-corrosive apparatus
Technical field
The utility model relates to shaft tower field of reinforcement, is especially a kind of power transmission sequence pole and tower foundation anti-corrosive apparatus.
Background technology
Power transmission sequence stimulates the menstrual flow often can be higher through groundwater table, and the area of heavy contamination, due to the impact of these severe external environment conditions, will certainly exist corrosion for being embedded in underground overhead line structures basis, is unfavorable for the safe operation of circuit.The anticorrosion common employing of traditional concrete foundation increases concrete label and increases the measures such as thickness of protection tier; so increased concrete consumption; correspondingly also increased the workload of construction; and cause steel bar stress to expose being corroded, certainly will having influence on the security of operation of power transmission sequence just in case be subject to outside destroy or construction wrong.
Summary of the invention
For the pole and tower foundation existing in prior art, easily corrode, the problems such as application life is short, the technical problems to be solved in the utility model is to provide a kind of too fast corrosion that prevents and treats power transmission sequence pole and tower foundation, the easy-operating power transmission sequence pole and tower foundation of structure construction anti-corrosive apparatus.
The utility model adopts following technical scheme:
A kind of line pole tower basis anti-corrosive apparatus, comprise shaft tower, shaft tower is placed in underground by concrete, shaft tower inside is provided with many main muscle along shaft tower length direction, the periphery spaced set of main muscle has outer stirrup to form reinforcing cage, the buried part of shaft tower, at reinforcing cage equal intervals welding of aluminum magnesium alloy ring.
Preferably, the buried part of shaft tower from top to bottom respectively at 1/6 place, 1/2 place, the 5/6 place almag ring that is welded.
Many main muscle surrounds square structure, and square structure is connected and is welded with interior stirrup between both sides, and almag boxing is connected on the periphery of main muscle.
Almag ring and every main muscle weld together.
In another scheme, many main muscle surround circular configuration, and almag boxing is connected on the interior week of main muscle.Almag ring can also played the effect of reinforcing before corroding completely.
The utlity model has following advantage and beneficial effect:
The utility model does not change traditional rod tower foundation construction technology; by the corrosion that takes the lead in of the large alloy of activity; play the effect of protection reinforcing bar; due to spaced set; the uniformity consistency that has guaranteed corrosion, has solved a difficult problem for long-term puzzlement operation maintenance, effectively protects reinforcing bar not to be corroded; and improved with low cost, effect is remarkable.
Accompanying drawing explanation
Fig. 1 is the structural representation that embodiment 1 the utility model is used state;
Fig. 2 is cross-sectional view of the present utility model in Fig. 1;
Fig. 3 is the structural representation that embodiment 2 the utility model are used state;
Fig. 4 is cross-sectional view of the present utility model in Fig. 3;
In figure, 1 is main muscle, and 2 is outer stirrup, and 3 is interior stirrup, and 4 is concrete, and 5 is almag ring.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in detail.
Embodiment 1
As illustrated in fig. 1 and 2, the utility model provides a kind of line pole tower basis anti-corrosive apparatus, shaft tower, shaft tower is placed in underground by concrete 4, shaft tower inside is provided with many main muscle 1 along shaft tower length direction, main muscle 1 surrounds square structure, the periphery spaced set of main muscle 1 has outer stirrup 2 to form reinforcing cage, outer stirrup 2 welds together with a plurality of main muscle 1, on the outer stirrup 2 of square structure, be connected and be welded with interior stirrup 3 between both sides, make more firmly (see figure 2) of structure, in the buried part of shaft tower, at reinforcing cage equal intervals welding of aluminum magnesium alloy ring 5.In the present embodiment, the buried part of shaft tower from top to bottom respectively at 1/6 place, 1/2 place, the 5/6 place almag ring that is welded, make the region that each almag ring is protected equate (see figure 1), thereby reach the consistent object of depletion rate.Almag ring 5 is welded on the periphery of main muscle.Almag ring 5 welds together with every main muscle 1, between each member, connects into electric path.Because the metal active of almag ring is than large many of iron and steel, there iing groundwater table higher, the area of heavy contamination, thus by forming the corrosion of the almag ring of path, protected the safety to reinforcing bar in shaft tower.
Embodiment 2
Be with the difference of embodiment 1, as shown in Figures 3 and 4, many main muscle surround circular configuration, and almag boxing is connected on the interior week of main muscle.Periphery spaced set has outer stirrup to form reinforcing cage, there is no interior stirrup.Before being corroded, almag ring plays the effect of reinforcing.
