Construction method for vertical waterproof curtain of deep gravel pebble bed under fine-grained soil
The invention relates to a fine-grained soil underlying deep gravel pebble bed vertical waterproof curtain construction method which comprises the following steps: positioning the position of a waterproof curtain on the surface of a fine-grained soil layer, and constructing groove section guide walls on the two sides of the waterproof curtain; fine-grained soil of the fine-grained soil layer and gravel of the gravel layer are grabbed to the designed elevation from the position between the groove section guide walls on the two sides, so that a curtain groove section is formed, and slurry is injected synchronously; the grabbed fine-grained soil is crushed into muck; a mixture of muck, cement and water is stirred to form stirred cement-soil slurry, the stirred cement-soil slurry is poured from the bottom of the curtain groove section, and slurry is synchronously replaced; and the equal-thickness cement-soil wall waterproof curtain is formed through maintenance, a next groove section is constructed, and the groove section is closed on the plane. According to the method, the vertical waterproof curtain is implemented in the deep gravel pebble bed, and the maximum depth can reach 70 m; construction equipment is small, the requirement for the site is not high, muck can be utilized on site to manufacture cement soil slurry, wall protection slurry can be reutilized, the environment is protected, the manufacturing cost is saved, the process is simple, and operation is convenient.
本发明涉及一种细粒土下伏深厚砾卵石层竖向止水帷幕施工方法，包括如下在细粒土层表面定位出止水帷幕的位置，并施工止水帷幕两侧的槽段导墙；从两侧的槽段导墙之间抓出细粒土层的细粒土和砾卵石层的砾卵石至设计标高，以形成帷幕槽段，并同步注入泥浆；将抓出的细粒土破碎成渣土；将渣土、水泥和水的混合物搅拌形成搅拌水泥土浆，并从帷幕槽段底部灌入，并同步置换出泥浆；养护形成等厚水泥土墙止水帷幕，施工下一槽段，并使槽段在平面上闭合。本发明实现在深厚砾卵石层中实施竖向止水帷幕，最大深度可达到70m；施工设备较小，对场地要求不高，渣土可就地利用制造水泥土浆，护壁泥浆可二次利用，保护环境，节省造价，工艺简单，操作方便。
