Description
Technical field
The present invention relates to electrical equipment technical field, especially a kind of high strength, composite bed electric pole prepare maintaining process.
Background technology
Concrete wire pole belongs to reinforced concrete structure.Concrete tensile strength is about 1/10th of compression strength.Concrete wire pole during load, be subject to the effect of tension in defeated, distribution line.The pulling force produced is throughout each position of concrete wire pole, and whole electric pole all belongs to tensile region.So concrete wire pole the whole body all needs to put into reinforcing bar, generally with round steel or screw-thread steel.Armored concrete can ftracture owing to creating tension in maintenance with during shrinking.If obtain meticulous maintenance, then both can prevent cracking, the qualification rate of product can have been improved again.Although present problem is complete in technological procedure well construction and maintenance aborning, product before dispatching from the factory through close inspection can be also all qualified, but in use still there will be crackle, and the degree of depth of crackle, width and length can be got over along with the increase of service life serious.Especially close in ground level less than about one meter this segment distance, the degree of crackle is more serious.What have has even been covered with a large amount of iron rust around crackle.
The area had, winter minimum temperature can reach subzero 30-40 degree sometimes, and day and night temperature can reach more than 15 DEG C.Under such weather conditions, because reinforcing bar is different with the rate of expanding with heat and contract with cold of cement, be easy to crack due to stress difference, the general undulate of crackle instead of rectilinear reason, then that the adhesion of these sands and stone surface is generally less than the adhesion of sand and stone inside owing to containing a large amount of sands and stone in concrete.Concrete is when stressed cracking, and crackle must appear at the surface of sand and stone, seldom appears at the centre of sand and stone, and naturally crackle also can be only waveform instead of rectilinear.In addition, the moisture infiltrated in crackle will freeze at night, turned to water again by day.In this change, because the volume of the volume ratio water of ice is large, so will make a volumetric work to external world when water becomes ice, often make a volumetric work, crackle will be broadened a bit, in the course of time, substantially reduces the service life of concrete wire pole.
