Conclusions

  1. 1.

    Analytical and graphical relationships between the number of pipes, their diameter, the flow of asphaltic material that can be passed through them and their depth of the immersion were derived on the basis of theoretical and experimental studies on the technology of the underwater placement of an asphalt lining in repairing hydraulic structures.

  2. 2.

    The temperature-energy regime of the system encountered in placing an underwater asphaltic lining, which permits proper designation of pipe diameter as a function of the temperature of the asphaltic material and the water surrounding the delivery pipes, is studied.

  3. 3.

    For lining under water, it is recommended that an asphalt mastic or solutions be employed as the most transportable materials, which make it possible to (fill all available recesses and which do not delaminate during transportation and lining.
