Abstract

The invention relates to methods for repairing reinforced concrete pipes and may find application in the energy, ferrous and non-ferrous metallurgy, chemical and other industries when performing repair and construction works. The purpose of the invention is to reduce the complexity of repairing industrial chimneys. After you inspect the damaged lining sections as a result of the inspection of the pipe, they decide to disassemble them. For this purpose, a lifting platform is assembled in the pipe base, which is laid on the Rus intended for disassembly. Dismantling of the lining layer is from top to bottom. The battle of the brick is dumped into the flue, from where it is lifted up out and loaded into the vehicle. Relieving sections of the barrel from lining, cut down niches for attaching additional reinforcement to the vertical reinforcement of the barrel. After the reinforcement is weighed, the lining is laid with mats with a height of 1-1.5 m. The mated lining is incubated for 12 hours at a temperature of at least 15 ° C until the lining reaches at least 30% of the design strength and the material is laid on its outer side with low adhesion to concrete, for example roofing material, after which the gap formed between the barrel and the lining is filled with light keramsitobeton. fc / f fe

Description

The invention relates to methods for the repair of reinforced concrete pipes and may find application in the energy, ferrous and non-ferrous metallurgy, chemical and other industries when performing repair and construction works.

The purpose of the invention is to reduce the complexity and material consumption of the repair of industrial chimneys.

The above distinguishing features from the prior art are sufficient to carry out the invention. all cases covered by the requested scope of legal protection.

The possibility of carrying out the invention is confirmed by the following example.

After you inspect the damaged lining sections as a result of the inspection of the pipe, they decide to disassemble them. For this purpose, a lifting platform is assembled in the pipe base, the beams and the wood flooring of which are laid of the appropriate diameter depending on the diameter of the lining on the ruse intended for dismantling. Dismantling the destroyed layer of the lining is from top to bottom. The brick fight and the remnants of thermal insulation are discharged into the gas duct, from where they are lifted up through the hole in the gas duct and loaded into a wagon or dump truck. The sections of the trunk freed from the lining are cleaned of adhering particles of the dust /) and the niches are cut down to attach additional reinforcement to the ver00

Tikalnym fittings trunk. After weighed reinforcement, the lining is laid with mats with a height of 1-1.5 m. The laid lining is incubated for 12 hours at a temperature of at least 15 ° C until the lining reaches at least 30% of the design strength, and laid on its outside material with low adhesion to concrete, for example, roofing material, after which the gap formed between the barrel and the lining is filled with lightweight claydite-concrete of class B12.5, No. 8, with a combined mass in the dried state of 1200-1400 kg / m3.

These operations continue to be carried out until the laying of the entire area freed from the destroyed lining.

SUMMARY OF THE INVENTION A method for repairing chimneys, including removing a damaged lining, reinforcing a bearing barrel with a reinforced concrete cage, replacing the lining in the damage zone with laying it with russes, covering a tout, and so that the reinforcing cage is made from the inside of the bearing barrel by installing additional reinforcement on the inside of the trunk exposed to the exposed lining of the trunk with Russes, lay the lining with maintaining the masonry of each Rus to set at least 30% of its design strength, while closing t lining on its outer periphery a material with low adhesion to concrete, and then filled into a gap between the carrier and the barrel lining heat insulating lightweight structural concrete.
