Assigment of the initial technological parameters of grouting construction joints of concrete dams
Conclusions 1. Opening of a joint, measured at individual points or determined by calculation, does not reflect its real hydraulic passability. 2. To select the optimal technology of grouting a particular site, it is necessary to take into account its main hydraulic characteristics — the capacity of the joint and the tightness of the site, as well as the tightness of an autonomous injection system with valve outlets (when it is present), which should be determined during hydraulic testing by the standard method. 3. For a group of sites with the same size and design of the grouting systems and similar hydraulic characteristics, the grouting technology can be taken the same by the proposed method, refining it for sites with markedly different characteristics.
