The invention relates to an anti-seepage and reinforcement construction method for a dam, which is characterized in that two or more rows of mutually engaged concrete-filled steel tube mixing composite piles are arranged at the top of the dam, and the two rows of concrete-filled steel tube mixing composite piles are connected and fixed by arranging a reinforced concrete top beam at the top to form an anti-seepage and reinforcement structure; two rows of concrete-filled steel tube mixing composite piles arranged in parallel are arranged at the landslide position of a dam, and the two rows of concrete-filled steel tube mixing composite piles are connected and fixed by arranging a reinforced concrete top beam at the top to form a gate-type anti-sliding row pile structure; when the concrete-filled steel tube mixing composite pile is constructed, the steel tube is rotated to sink, the mixing head arranged at the bottom of the steel tube cuts a soil body, and cement paste is sprayed to the mixing head through the grouting steel tube synchronously, so that a mixing pile is formed. The method has the advantages that the characteristics of a rigid pile and a flexible pile are combined, the reinforcing effect can be effectively improved under the condition that the economical efficiency is guaranteed, meanwhile, construction is easy, machines and tools are short, small and flexible, and construction is fast.
本发明涉及一种堤坝防渗、加固施工方法，在堤坝的坝顶位置设置两排或两排以上相互咬合的钢管混凝土搅拌复合桩，两排钢管混凝土搅拌复合桩之间通过顶部设置钢筋混凝土冠梁连接固定构成防渗加固结构；在堤坝的滑坡位置设置两排平行设置的钢管混凝土搅拌复合桩，两排钢管混凝土搅拌复合桩之间通过在顶部设置钢筋混凝土冠梁连接固定构成门式抗滑排桩结构；钢管混凝土搅拌复合桩施工时，将钢管旋转下沉，令钢管底部设置的搅拌头切割土体并同步通过注浆钢管向搅拌头喷注水泥浆从而形成搅拌桩。本发明的优点是：结合了刚性桩和柔性桩的特点，可以在保证经济性的情况下，有效的提高加固效果，同时其施工简单、机具矮小灵活、施工快。
