The invention discloses a
building construction rainfall drainage structure. The
building construction rainfall drainage structure comprises a drainage channel, wherein the upper end of the drainage channel is open, the inner bottom wall of the drainage channel is obliquely arranged downwards from left to right, a
water seepage net plate is fixedly connected to the upper end of the drainage channel in a sealed mode, two rows of circular
insertion blocks which are symmetrical about the
transverse axis of the
water seepage screen plate are fixedly embedded in the upper end of the
water seepage screen plate, a
water pumping rod is vertically and movably inserted in each circular
insertion block, the lower end of each
water pumping rod extends into the drainage channel, a water suction cavity is formed in each
water pumping rod, the lower end of each water suction cavity communicates with the drainage channel, a plurality of water inlets are formed in the
peripheral surface of the upper end of each water pumping rod, and fixed blocks are fixedly connected to the front and rear positions of the end, which is located in the drainage channel, of each water pumping rod. The
building construction rainfall drainage structure has the advantages that rainfall accumulated water of a construction site can be continuously and effectively drained, the structure adapts to different rainfall intensities and has the effects of
energy conservation and environment friendliness, and the
water level is prevented from rising.
