Cohesive soil initial dam structure for upstream type tailing pond
The invention discloses a cohesive soil initial dam structure for an upstream type tailing pond. The cohesive soil initial dam structure is characterized in that an initial dam body bottom impermeable layer is laid at the bottom of an initial dam body first, an initial dam upstream seepage drainage arris (1) and an initial dam downstream seepage drainage arris (1') are respectively arranged on the upstream and downstream of an initial dam, an initial dam seepage drainage mattress (2) is laid on the initial dam body bottom impermeable layer, and the lower ends of vertical seepage drainage blind drain pipes (3) communicate with the initial dam seepage drainage mattress (2); an inclined drainage blind drain is pre-buried in the contact position of the initial dam and a mountain, and a transverse blind drain is pre-buried in the contact position of the initial dam and the mountain; and the initial dam is built layer by layer from bottom to top and is compacted layer by layer, and an impermeable slope protection layer (5) is constructed on the upstream slope surface of the initial dam. According to the cohesive soil initial dam structure, the inclined drainage blind drain, the transverse blind drain, the initial dam upstream seepage drainage arris, the initial dam downstream seepage drainage arris, the vertical seepage drainage blind drain pipes and the initial dam seepage drainage mattresses jointly form a combined drainage system, so that the seepage line of the dam body can be effectively reduced.
本发明公开了一种用于上游式尾矿库的粘性土初期坝结构，先铺在初期坝体底铺设初期坝体底部防渗层，在初期坝上、下游分别设置初期坝上游排渗棱体(1)、初期坝下游排渗棱体(1，)，在初期坝体底部防渗层上铺设初期坝排渗褥垫(2)，竖向排渗盲沟管(3)的下端与初期坝排渗褥垫(2)连通；在初期坝与山体接触部位预埋斜向排水盲沟，在初期坝与山体接触部位预埋横向盲沟；自下而上逐层堆筑初期坝，并分层压实，在初期坝上游坡面上施工防渗护坡层(5)。本发明之斜向排水盲沟、横向盲沟、初期坝上游排渗棱体、初期坝下游排渗棱体、竖向排渗盲沟管与初期坝排渗褥垫共同构成组合式排渗系统，可以有效降低坝体浸润线。
