Abstract
The article is devoted to the experimental testing of clinker bricks for the expediency of its use in the restoration of sewage collectors. The article provides a review of publications in the field of improving the operational reliability of sewer collectors. It was determined that, depending on the emergency, it is advisable to use traditional methods of repairing collectors using materials that can withstand biogenic corrosion. The purpose of this work is to conduct experimental testing of samples of bricks, presented on the market of Ukraine, with a view to the expediency of their use in restoration works in the conditions of aggressive sewage environment. The following research results were obtained: analysis of the clinker brick market of Ukraine was carried out and samples were obtained for testing; experimental testing of selected samples of bricks in the conditions of their operation in an aggressive sewage environment.The characteristics of 18 specimens of bricks that were tested before and after being in the aggressive environment of one of the sewer collector mines were investigated. To investigate the effect of strength, density and water absorption of 18 samples of clinker brick on the resistance of the aggressive environments of the sewer mine were immersed in mine № 3 of the Main sewer collector for 90 days. The compressive strength of the samples was tested before immersion of the samples in the aggressive environment of the sewer collector and after 90 days of stay there. The results were obtained, according to which the list of samples of clinker bricks, which are capable of counteracting gas corrosion and are expedient for use in the restoration works of networks of drainage, were selected. From now on, the selection of the yoke, which is presented on the Ukrainian market, is the reason for the seams to help protect the design and construction of the crypt of the collection collector from other materials.
