Method for forming bored pile by pre-grouting cement mortar
The invention discloses a method for forming a bored pile by pre-grouting cement mortar, and belongs to the technical field of bored piles. The method for forming the bored pile by pre-grouting the cement mortar comprises the following steps of: step 1, performing concealing acceptance before pouring concrete; step 2, preparing the cement mortar with the required larger consistency and the concrete required for the pile body according to the designed pile diameter, the pore-forming actual hole expansion coefficient, and the thickness of the cement mortar to be pre-grouted; step 3, pouring thecement mortar and concrete in sequence; step 4, performing concrete curing. The method for forming the bored pile by pre-grouting the cement mortar uses the cement mortar poured first to meet the moisture absorption of the hole wall soil layer, which avoids the loss of the concrete moisture of the pile body, and effectively guarantees the quality of the pile.
本发明公开了一种钻孔灌注桩预灌水泥砂浆成桩方法，属于灌注桩技术领域。本发明的步骤为：步骤一：灌注混凝土前隐蔽验收；步骤二：根据设计桩径以及成孔实际扩孔系数，由拟预灌注水泥砂浆厚度，准备好所需稠度较大的水泥砂浆和桩身所需混凝土；步骤三：依次灌注水泥砂浆和混凝土；步骤四：混凝土养生。本发明以先灌注的水泥砂浆来满足孔壁土层对水分吸收，避免了桩身混凝土水分的损失，有效保证成桩质量。
