Drainage method for bank slope dam section of gravity dam
The invention discloses a drainage method for a bank slope dam section of a gravity dam, which comprises the following steps of: pre-burying drainage steel pipes in a dam body of the bank slope dam section, and obliquely arranging the drainage steel pipes; after a dam body of a bank slope dam section is constructed to a certain height below a dam crest, holes are drilled at intervals along the central axis of the plane of a drainage steel pipe, the centers of the holes are all located on the central axis of the plane of the drainage steel pipe, a permeable pipe is placed in a lower drainage hole, and a cap is additionally arranged on the top of an upper drainage hole; and after the upper drainage hole is packaged, the dam body is poured to the designed elevation. According to the method, traditional galleries are replaced with buried pipes, smooth drainage of seepage water of the bank slope dam section is achieved, the drainage layout problem of a small bank slope dam body is solved, only drilling and burying of drainage steel pipes are needed, the dead weight of the dam body is basically not reduced, and stability and safety of the dam body are facilitated; moreover, the upper drainage holes can adopt a post-drilling mode, so that the influence on dam body construction is reduced, and the total construction period of the dam body is shortened.
本发明公开了一种重力坝岸坡坝段的排水方法，其是在岸坡坝段的坝体内预埋排水钢管，排水钢管倾斜布设；将岸坡坝段的坝体施工至坝顶下方一定高度后，沿排水钢管的平面中轴线间隔钻孔，孔的中心均位于排水钢管的平面中轴线上，向下排水孔内放置一个透水管，并在上排水孔的顶部加装盖帽；待上排水孔封装完成后，将坝体浇筑至设计高程。本发明通过埋管代替了传统的廊道，实现了岸坡坝段渗透水的顺畅排水，解决了小体型岸坡段坝体的排水布设难题，且本发明只需钻孔和埋设排水钢管，基本不减小坝体自重，有利于坝体稳定安全；再者，本发明的上排水孔可采用后钻孔方式，减少对坝体施工的影响，缩短坝体总工期。
