Title:
METHOD FOR CONSTRUCTING NOVEL STARTER DAM SUITABLE FOR UPSTREAM TAILINGS POND
Document Type and Number:
WIPO Patent Application WO/2022/160713
Kind Code:
A1
Abstract:
Disclosed is a method for constructing a novel starter dam suitable for an upstream tailings pond, comprising: laying a starter dam body bottom anti-seepage layer; providing a starter dam upstream seepage drainage prism body (1) and a starter dam downstream seepage drainage prism body (1,) respectively on the upstream and downstream of the starter dam, and laying a starter dam seepage drainage mattress (2) on the starter dam body bottom anti-seepage layer, lower ends of vertical seepage drainage blind ditch pipe (3) being in communication with the starter dam seepage drainage mattress (2); pre-embedding inclined drainage blind ditches at positions where the starter dam contacts mountain bodies, and pre-embedding transverse blind ditches at positions where the starter dam contacts the mountain bodies; and building the starter dam layer by layer from bottom to top, and compacting same in a layered manner, and constructing an anti-seepage protective slope layer (5) on an upstream slope surface of the starter dam. The present invention has advantages of low construction cost, small amount of stones used, and good water-permeable effect. By designing a drainage facility inside a starter earth dam, the earth dam meets the requirement of a water-permeable dam.
