Construction method for basement large-rock-block self-draining ground

The invention discloses a construction method for basement large-rock-block self-draining ground. The method includes the steps of 1, cleaning a base layer; 2, finding a high standard and a horizontal line; 3, prefabricating drainage concrete blocks; 4, laying rock blocks; 5, laying non-woven fabrics; 6, arranging templates; 7, leveling cement mortar; 8, pouring fine-stone concrete. On the basis of structural water prevention, the method uses the large rock blocks to enable to form all direction extending multi-layer-space drainage pathway, and the drainage ability is strong; the method takes drainage as the principal thing, greatly improves the waterproof ability of the structure, is convenient to maintain, and saves the cost. 本发明公开了种地下室大块石自排水地面施工方法，包括以下步骤：步骤，基层清理；步骤二，找准标高、弹水平线；步骤三，预制排水混凝土块；步骤四，铺设块石；步骤五，铺设无纺布；步骤六，模板支设；步骤七，水泥砂浆整平；步骤八，细石混凝土浇筑。本发明在结构防水的基础上，采用大块石使板底形成四通八达的多层空间排水通路，排水能力强；采用以排为主的思路，极大的提高了结构的防水能力，维护方便，节省费用。
