Prefabricated abutment underwater water stopping method
The invention discloses an underwater water stopping method for prefabricated abutments. The underwater water stopping method comprises the following steps that S1, the prefabricated abutments are arranged on the two sides of a steel pipe cast-in-place pile; s2, an annular water stop tray is fixedly arranged below the bottom of the prefabricated abutment, and the annular water stop tray is coaxially arranged on the periphery of the steel pipe cast-in-place pile in a surrounding mode; s3, an annular rubber water stop belt is arranged in a gap between the bottom face of the prefabricated abutment and the top face of the annular water stop tray; s4, a piece of waterproof cloth is arranged on the top face of the annular water stop tray, the waterproof cloth is annularly arranged, one end of the waterproof cloth is connected to the annular water stop tray through an adhesive, and the other end of the waterproof cloth surrounds and is fixed to the annular tensioning and tightening device through the adhesive; and S5, the annular tensioning and tightening device is tightened, the annular tensioning and tightening device shrinks to be tightly attached to the steel pipe cast-in-place pile and makes close contact with the cast-in-place pile, water is isolated through the waterproof cloth, and water stopping of the vertical gap between the prefabricated abutment and the cast-in-place pile is achieved. The device has a safe and efficient water stopping effect.
本发明公开了一种预制墩台水下止水方法，包括以下步骤：S1、在钢管灌注桩两侧设置预制墩台；S2、在预制墩台底部下方固定设置环形止水托盘，所述环形止水托盘同轴环设于钢管灌注桩外周；S3、在预制墩台底面与环形止水托盘顶面的间隙中设置环形橡胶止水带；S4、在环形止水托盘顶面设置一道防水布，防水布呈环形设置，防水布一端通过胶黏剂连接在环形止水托盘上，防水布另一端通过胶黏剂环绕并固定在环形张拉收紧装置上；S5、收紧环形张拉收紧装置，使环形张拉收紧装置收缩紧贴钢管灌注桩，与灌注桩紧密接触，通过防水布将水隔离，实现预制墩台和灌注桩之间竖向间隙的止水。本发明具有安全、高效的止水效果。
