The slope protection device for the water conservancy project relates to the technical field of slope protection and comprises a slope body, an intercepting
ditch is formed in the top end of the slope body, a filtering
assembly is embedded in the intercepting
ditch, a plurality of drainage chutes are fixedly connected to the outer surface of the slope body, and baffles are fixedly connected between the drainage chutes; the top end of the slope body is provided with an intercepting
ditch, the top end of the slope body is provided with a filtering
assembly, the filtering
assembly comprises a front-end
water storage tank, a connecting tank, a rear-end
water storage tank, a groove hole, a
butt joint pipe, a bottom plate, a hanging rod, a cover plate and a drainage hole, and the top end of the slope body is provided with the intercepting ditch and the filtering assembly composed of the front-end
water storage tank, the connecting tank and the rear-end
water storage tank is embedded; by means of the structure, the amount of
silt flowing into the lower portion of the slope body is greatly reduced, when it rains, rainwater and the
silt brought by the slope top enter the water
storage area, the rainwater and the
silt can be deposited on the bottom plate under the action of gravity to be accumulated, most of the silt is filtered out, water and
soil loss caused by rainwater washing is effectively prevented, and the good protection effect on the slope body is achieved.
