Abstract
The invention discloses a composite layer telegraph pole manufacturing and maintaining process which includes the following steps: A. first manufacturing a common steel bar cement hollow rod body, and then pouring epoxy resin in the hollow rod body; B. moving an obtained product into a high pressure operation chamber, pouring a cement layer on an epoxy resin pouring layer in a full covering mode to enable the epoxy resin pouring layer to be located in the high pressure closed space between the cement layer and the hollow rod body; C. conducting drilling operation on the cement layer at the top end or the bottom end of a telegraph pole in a circle area and communicating the inside of the hollow rod body and the external atmosphere. The telegraph pole has the advantage of natural maintaining. When the hollow rod body is cracked due to winter low temperature and day and night temperature difference change, the epoxy resin pouring layer on the outside of the hollow rod body permeates cracks naturally and slowly. Especially when the temperature rises in the summer, the epoxy resin completely permeates the cracks to repair the rod body, and the natural maintaining effect that the hollow rod body is cracked in winter and repaired in summer is achieved.
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 when load, be subject to the effect of tension in defeated, distribution line.The pulling force producing spreads all over 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 people's reinforcing bar, generally with round steel or screw-thread steel.Armored concrete can ftracture owing to having produced tension in maintenance with during shrinking.If obtain meticulous maintenance, both can prevent cracking, can improve again the qualification rate of product.Although present problem is aborning completely according to technological procedure well construction and maintenance, product can be also all qualified through strict inspection before dispatching from the factory, but in use still there will be crackle, and the degree of depth of crackle, width and length can get over along with the increase of service life seriously.Especially approaching ground level below approximately one meter in 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.
In the area having, 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 the rate of expanding with heat and contract with cold of reinforcing bar and cement is different, be easy to because stress difference cracks, the general undulate of crackle instead of rectilinear reason, be owing to containing a large amount of sands and stone in concrete, the adhesion on these sands and stone surface is generally less than the adhesion of sand and stone inside.Concrete is in the time of stressed cracking, and crackle must appear at the surface of sand and stone, seldom appears at the centre of sand and stone, and naturally and understandably crackle can be only also waveform instead of rectilinear.In addition, the moisture infiltrating in crackle will freeze at night, turned to again by day water.In this variation, because the volume of the volume ratio water of ice is large, thus when becoming ice, water will make to external world one time volumetric work, volumetric work of every work, and crackle will be broadened a bit, in the course of time, has greatly shortened the service life of concrete wire pole.
