Building cast-in-situ bored pile foundation pile head breaking method
A building cast-in-situ bored pile foundation pile head breaking method comprises the following steps that a, before cast-in-situ bored pile construction, a pile casing door capable of being opened and closed is arranged on a pile foundation pile casing, and a filter screen is fixedly arranged on the inner side of the pile casing door; b, the site is leveled, the site elevation is consistent with the elevation of the over-grouting part of the top of the pile foundation, and the pile casing is embedded into the pile hole; c, after the pile hole is formed, a reinforcement cage is put in, the surface of the reinforcement of the over-poured part at the top of the pile foundation is coated with antirust paint, and a rubber pipe is arranged in a sleeving mode; d, a flow guide slurry groove is excavated in the pile casing door; e, the pile casing door is opened, and the concrete cement paste of the over-grouted part above the door bottom elevation flows out; and f, after the concrete of the pile body reaches the design strength, the concrete of the over-grouting part above the door bottom elevation is excavated, and meanwhile, the surface of the pile head is subjected to chiseling treatment. By the adoption of the method for breaking the pile head of the building cast-in-situ bored pile foundation, shaking generated by the lower pile body when the pile head is broken can be reduced, the process is simple, and time and labor are saved.
一种建筑钻孔灌注桩基础桩头破除方法，包括如下步骤：a、在钻孔灌注桩施工前，在桩基护筒上设置可开关的护筒门，在护筒门内侧固定设置过滤网；b、平整场地，场地标高与桩基顶部超灌部分标高一致，将护筒埋入桩孔位置；c、在桩孔成孔完成后，放入钢筋笼，桩基顶部超灌部分的钢筋表面涂刷防锈漆，并套入橡胶管；d、在护筒门处开挖导流浆槽；e、打开护筒门，门底标高以上的超灌部分混凝土水泥浆流出；f、待桩身混凝土达到设计强度后，将门底标高以上的超灌部分的混凝土挖除，并同时将桩头表面进行凿毛处理。采用本发明的一种建筑钻孔灌注桩基础桩头破除方法可以减少破除桩头时下部桩身产生的晃动，工序简单，省时省力。
