Sludge-Removing structure easy to remove bottom sludge piled to rainwater storage tank

摘要

In order to achieve the above object, the present invention is a sludge removal structure for removing the bottom sludge formed in the rainwater reservoir formed under the ridge ground surface extending to a certain height from the ground, where rainwater is collected, the bottom surface is It is formed in the form of the inclination angle of the omnidirectional, the lower portion of the inclined to collect the rainwater reservoir and the lower portion of the inclined to gather the sludge collecting and sludge collecting and collecting the sludge And a sludge discharge pipe for discharging the sludge out of the ground. Since the present invention separates and discharges the sludge collected through the sludge collecting port out of the rainwater storage tank, there is an effect that can remove the sludge without overall pollution of the water quality.
