The invention relates to a construction method for pouring dam foundation concrete in a zone with centralized water gushing. The technical problem to be solved by the invention is to provide the construction method for pouring the dam foundation concrete in the zone with the centralized water gushing, which has the advantages of low investment, simpleness in process and effectiveness, and aims atensuring the strength and quality of the foundation concrete. The technical scheme for solving the problem is as follows: leveling a foundation around a centralized water gushing point; covering a grouting box on the water gushing point; then connecting two steel pipes on the top part of the grouting box; pouring the dam foundation concrete, and simultaneously utilizing the steel pipes for water pumping till the final setting of the concrete; and finally utilizing the steel pipes to carrying out grouting treatment on the centralized water gushing point in the grouting box. The construction method is applicable to water conservancy and hydropower engineering.
