Grouting the joints of the Krasnoyarsk hydroelectric-station dam
Conclusions The constructional decision adopted for preparation of the placed concrete for the dam and for rendering it monolithic made it possible to carry out properly-timed grouting of the structure.The insufficient opening of individual joints led to additional expenditure on their grouting.In order to produce an optimum opening of a joint it is expedient to stipulate the distance between joints as not less than 13 to 15 m.The progressive variation of the temperature of placed concrete does not fully reflect the nature of the joint opening. In order to obtain more complete data on opening of the joint, it is necessary to install telemetered joint gages in those zones of the structure which are characterically representative of the concrete placement and cooling procedures.The working pressure in the joint during the grouting period should be specified according to the deformations permissible.
