Вulgakov I. Developing the organizational and technical solutions for increasing durability of tunnel sewage collectors

Object: The process of repair and restoration of sewage tunnel collector; aim: scientific rationale and development of technical, technological and organizational solutions that increased operational durability of sewage tunnel collector; Methods: Bibliographic search of field observations, laboratory tests, finite element method; novelty: investigated the main reasons leading to the destruction of sewage tunnel collector and marked the stages of execution of the repair work; searched efficient building materials, structures and technologies, which in its properties and solutions provide strength, corrosion resistance and water resistance of structures that are used to restore the sewer tunnel collectors; Results: Using the finite element method simulations performed general construction work of a collector array with the ground, using the model selected recovery options reservoirs with characteristics of load-bearing capacity.
