The invention provides a cover plate construction method for tooth-shaped curtain expansion pile supporting. The cover plate construction method comprises the following steps that S1, tooth-shaped curtain construction is conducted on the periphery of a foundation pit; s2, pile head muck and frost boiling solidified bodies of the tooth-shaped curtains are cleaned, and soil bodies between the tooth-shaped curtains are excavated after cleaning is completed; s3, after a soil body on the surface of the tooth-shaped curtain is cleaned, a pouring formwork corresponding to the cover plate is arranged above the tooth-shaped curtain; s4, reinforcing steel bars are bound in the formwork, and the reinforcing steel bars are connected with the tooth-shaped curtain; and S5, concrete pouring is conducted in the formwork, and after concrete is formed, the formwork is removed to form the cover plate. The concrete cover plate replaces and omits a top beam at the top of a traditional support pile, reinforced concrete materials and manufacturing cost are saved, the concrete cover plate located at the top of the tooth-shaped curtain is connected with the tooth-shaped curtain to form an overall working condition, and the overall working performance of the tooth-shaped curtain is improved.

本发明提供一种用于齿形帷幕扩体桩支护的盖板施工方法，包括以下步骤：步骤S1，在基坑外周进行齿形帷幕施工；步骤S2，对齿形帷幕的桩头渣土及翻浆固结体清理，清理完成后对齿形帷幕之间的土体进行开挖；步骤S3，清理齿形帷幕表面土体后，在齿形帷幕的上方设置对应盖板的浇注模板；步骤S4，在模板内进行钢筋绑扎，使钢筋与齿形帷幕进行连接；步骤S5，在模板内进行混凝土浇筑，待混凝土成型后拆除模板形成盖板。混凝土盖板替代并省去了传统支护桩顶部的冠梁，节省钢筋混凝土材料和造价，位于齿形帷幕顶部的混凝土盖板与齿形帷幕联系形成整体工作条件，增加了齿形帷幕的整体工作性能。
