Method for controlling elevation of cage top of long spiral pressure grouting pile
The invention discloses a control method for cage top elevation of a long spiral press-grouting pile, which relates to the technical field of pile foundation construction and comprises the following steps of: fixedly taking a pile position, measuring and setting out through measuring equipment according to a preset measuring control point of a pile foundation, obtaining the pile position, and marking the pile position; hole forming is conducted, specifically, the long spiral drilling machine is moved to the position of the pile position, and drilling is conducted to the designed depth; concrete pouring is conducted, specifically, the concrete is conveyed to the hole bottom through a drill rod core pipe of the long spiral drilling machine till the concrete is poured to the elevation of a pile foundation platform; and the reinforcement cage is lowered, and the reinforcement cage connected with the measuring reinforcement is pressed into the concrete until the measuring reinforcement exceeds the elevation of the pile foundation platform to the preset height. According to the control method for the cage top elevation of the long spiral press-grouting pile, the measuring steel bars are connected to the steel reinforcement cage and exposed on the outer side of the concrete, the cage top elevation can be controlled by measuring the distance of the steel bars extending out of the pile foundation platform elevation, and the controllability of the cage top elevation of the steel reinforcement cage is improved.
本发明公开了一种长螺旋压灌桩笼顶标高的控制方法，涉及桩基础施工技术领域，包括步骤：定取桩位，根据桩基的预设测量控制点，通过测量设备进行测量放线，获取桩位，并对桩位进行标记；成孔，将长螺旋钻机移动至桩位的位置上，并钻孔至设计深度；混凝土浇筑，通过长螺旋钻机的钻杆芯管将混凝土送至孔底，直至将混凝土浇筑至桩基平台标高；下放钢筋笼，将连接有测量钢筋的钢筋笼，压入混凝土内，直至测量钢筋超出桩基平台标高至预设高度。本发明提供的长螺旋压灌桩笼顶标高的控制方法，通过在钢筋笼上连接测量钢筋，显露在混凝土的外侧，可通过测量钢筋伸出桩基平台标高的距离，实现对笼顶标高的控制，提高了钢筋笼笼顶标高的可控性。
