Early treatment should any problems timely detection and treatment, for the case of breakage of the cement pole, from the crack should occur, because the perspective of the development of early treatment to prevent or slow the development of the crack is very important. Overall, the crack can be repaired or replace the rod. Patch closure should follow the principles of weather resistance, high strength and long-lasting, epoxy after a reasonable formula to meet the requirements for a large area of ​​the crack, crack serious concrete poles can be segmented rod replacement or full replacement.
     1, fiberglass wrapped around the shaft when there are several methods of cracking or dense lines, local crisp crack, crack when weld crisp, use epoxy fiberglass parts to crack and split cakes wrapped. Before wrapping the original surface clean, crisp part knockout split and filled with cement. When wrapped in a layer of epoxy resin brush, including a layer of glass fiber fabric, each brush to be wrapped in a layer of air is discharged, the outermost layer of glass cloth epoxy To completely seal, can not have bubbles. Epoxy resins can not be too thin, the thickness of paint can not be guaranteed. Depending on the number of layers of glass fiber cloth wrapped shaft extent of the damage, are generally less than 3 layers. This method not only crack closed tight, and has increased the intensity of effect.
     2, when the epoxy squeeze wiping surround the shaft sealing method if only 1 to 2 cracks, or other fixtures shaft there can not be wrapped, can be modulated slightly viscous epoxy resin into plastic soft bag, through soft bag opening size and strength to grasp with both hands squeeze out the amount, moving the extrusion direction along the crack, plugging of the formation not too thick, block width is about three times the width of the crack.
    3, reinforced concrete piling method is generally the root site of the rod bending stress is relatively large, and close to the soil and moisture can form inside the water storage, freezing, is the site easy to crack, and crack development is relatively fast. If the next line of the beam cross hoop on the installation location by comparison, you can root around the rod to form protective cast reinforced concrete piles. Retaining pile thickness of 150 ~ 200 mm, the ground below about 0.5 m, height above the ground does not exceed 1.5 m, or affect the use of foot wear rod. .
    4, replace the rod segments law practice cement poles cracks generally occur locally, mostly related to paragraph 1 to 2 bar section, when large cracks around the rod segment, crack length, when the gap width or multiple crisp crack, the segment can be replacement.
    5, full bar replacement method when there exist different severity crack above the rod segment and 3 above, you can implement the whole rod replacement.
