Steel pipe pile and steel sheet pile combined pile sinking process and combined pile sinking device thereof
The invention relates to a steel pipe pile and steel sheet pile combined pile sinking process and a combined pile sinking device thereof, and belongs to the technical field of pile foundation construction. The steel pipe pile and steel sheet pile combined pile sinking technology comprises the following steps that S1, steel pipe piles and steel sheet piles are assembled to form a combined body of the steel pipe piles and the steel sheet piles; s2, according to the size of the assembly, the sizes of a first hydraulic clamp, a second hydraulic clamp and a third hydraulic clamp are set, and the three hydraulic clamps are installed on sliding rails of a vibratory hammer correspondingly; s3, the first hydraulic clamp and the second hydraulic clamp are arranged on the two sides of the top of the steel pipe pile in a clamped mode correspondingly, the third hydraulic clamp is arranged on the top of the steel sheet pile in a clamped mode, and the gravity center of the vibratory hammer and the gravity center of the combined body are located on the same vertical line; and S4, combined pile sinking is conducted. According to the combined pile sinking process, the steel pipe piles can be prevented from rotating in the soil body through resistance of the steel sheet piles, so that the lock catches of the steel sheet piles and the steel pipe piles are in lap joint according to designed positions, and deviation of actual construction positions is avoided.
本发明涉及一种钢管桩与钢板桩组合沉桩工艺及其组合沉桩装置，属于桩基础施工技术领域。该钢管桩与钢板桩组合沉桩工艺包括以下步骤：S1，将钢管桩与钢板桩进行组装，形成钢管桩与钢板桩的组合体；S2，根据组合体的尺寸，设置第一液压夹具、第二液压夹具、第三液压夹具的尺寸，并将三个液压夹具分别安装于振动锤的滑轨上；S3，将第一液压夹具、第二液压夹具分别夹设于钢管桩顶部的两侧，将第三液压夹具夹设于钢板桩的顶部，使振动锤的重心与组合体的重心位于同一垂线上；S4，进行组合沉桩。该组合沉桩工艺能够利用钢板桩的阻力避免钢管桩在土体中旋转，从而确保钢板桩的锁扣与钢管桩按照设计位置进行搭接，避免实际施工位置出现偏差。
