The purpose of the work is the substantiation and development of technical, technological and organizational solutions that will form the basis of technological support for restoring the operability of shallow sewage pipelines. To achieve the set goal, the following tasks must be solved: -the technical condition of sewage pipelines was analyzed based on the analysis of their service life, the dynamics of the ingress of wastewater from the pipeline into the soil and groundwater, based on the results of their technical survey; the existing systems for monitoring the state of sewage pipelines have been improved; -the factors that shorten the service life of sewage pipelines, affect their durability and reliability were investigated; corrosion processes were investigated; -constructive solutions of the new crypt part during the repair and restoration of sewage pipelines by the open method were developed; -using the finite element method, the bearing capacity of the newly created crypt part of sewer pipelines was calculated at different depths of their laying and loading; -organizational and technological solutions for the repair and restoration of sewage pipelines were developed with the support of the new crypt on the preserved tray part, using pneumatic and inventory formwork. Research methods. The methods of analysis and generalization were applied to substantiate the relevance, formulation of the purpose and objectives of the research. Statistical analysis is used to determine the technical condition of shallow sewage networks and the conditions for performing repair and restoration works. The calculation of structures for the restoration of the crypt using clinker bricks and a layer of reinforced concrete was performed using numerous methods implemented in software complexes based on the finite element method.
