Method for measuring perpendicularity deviation of pile hole of slurry retaining wall rotary drilling cast-in-situ bored pile
The invention discloses a method for measuring the perpendicularity deviation of a pile hole of a slurry retaining wall rotary drilling cast-in-situ bored pile. The method comprises the following steps that a fixing piece, a thin line and a floating piece are provided, wherein the fixing piece comprises a fixing ring; the fixing piece is fixed to the first end, which is used for lowering, of a rotary drilling pile reinforcement cage, and the fixing ring is located in the center of the first end; the fine line is arranged in the fixing ring in a penetrating mode and penetrates through the rotary drilling pile reinforcement cage, and the free end of the thin line which is located in the rotary drilling pile reinforcement cage is connected with the floating piece; the rotary drilling pile reinforcement cage is put into the pile hole in the state that the first end faces downwards, and the free end of the thin line which is located outside the rotary drilling pile reinforcement cage is located outside the pile hole; slurry is poured into the pile hole till the pile hole reaches a preset position, the floating piece floats on the liquid level of the slurry, and the thin line is in a tensioned state; the distance between the floating piece and the center of the top of the pile hole is obtained; and the distance D and the length H of the pile hole are substituted into I=D/H so as to obtain the perpendicularity deviation I of the pile hole. According to the method, the measurement of the perpendicularity is simple and convenient.
本申请公开了一种测量泥浆护壁旋挖钻孔灌注桩桩孔垂直度偏差的方法，包括以下步骤：提供固定件、细线、漂浮件，固定件包括固定环。将固定件固定在旋挖桩钢筋笼的用于下放的第一端，并使得固定环位于第一端的中心处。将细线穿设在固定环中，并贯穿旋挖桩钢筋笼，且将位于旋挖桩钢筋笼中的细线的自由端与漂浮件连接。将旋挖桩钢筋笼以第一端向下的状态下放至桩孔中，并使得位于旋挖桩钢筋笼外的细线的自由端位于桩孔外。向桩孔中灌注泥浆直至达到预设位置，并使得漂浮件漂浮在泥浆的液面上，且细线为拉紧状态。获取漂浮件和桩孔的顶部中心处之间的距离。将距离D和桩孔的长度H代入I＝D/H，获得桩孔垂直度偏差I。本申请的方法使垂直度的测量更简便。
