The utility model provides a prevent weighing down threshold for water conservancy project overflow surface surface concrete construction is in the step edge of lower floor's step concrete with arranged the concrete lower floor's step concrete straight intersegmental at a distance from one section distance and prevented weighing down threshold, the cross section that threshold are prevented weighing down by the concrete is the rectangle, and threshold covered whole overflow surface layer along the axial runner is prevented weighing down by the concrete. The utility model provides a pair of a prevent weighing down threshold for water conservancy project overflow surface surface concrete construction through adopting above structure, realizes the nothing top mould construction of overflow surface concrete, prevents in the mould work progress is pushed up to the nothing that the overflow surface concrete from weighing down to the gliding, and overflow surface size and outward appearance have been guaranteed to t
