Pile tip grouting device and method for steel pipe pile for high-frequency vibration pile sinking
The invention discloses a pile end grouting device and method for a steel pipe pile for high-frequency vibration pile sinking, the device comprises a cylindrical body with a central through hole, the cylindrical body is provided with a mounting hole used for being connected with the steel pipe pile for high-frequency vibration pile sinking, the side wall of the cylindrical body is provided with a plurality of vertical grouting channels, and the vertical grouting channels are communicated with the central through hole. An inner thread used for being connected with a grouting pipe is arranged in the vertical grouting channel, an upper transverse grouting channel and a lower transverse grouting channel are arranged on the side wall of the cylindrical body from outside to inside, and ports, in the side wall of the cylindrical body, of the upper transverse grouting channel and the lower transverse grouting channel are a first grouting outlet and a second grouting outlet in the diameter direction. And a third grouting outlet is formed in one end, far away from the mounting hole, of the vertical grouting channel. After pile sinking, grouting can be conducted through the first grouting outlet, the second grouting outlet and the third grouting outlet at the same time or firstly through the first grouting outlet and then through the second grouting outlet and the third grouting outlet into soil around the pile end of the steel pipe pile, the soil density and the structural strength are improved, and the bearing capacity of a pile foundation is improved.
本发明公开一种用于高频振动沉桩的钢管桩的桩端注浆装置及方法，该装置包括具有中心通孔的柱状体，所述柱状体设置有用于与高频振动沉桩的钢管桩连接的安装孔，所述柱状体的侧壁上设置有多个竖向注浆通道，所述竖向注浆通道内设置有用于与注浆管连接的内螺纹，所述柱状体的侧壁由外向内设置有上下两个横向注浆通道，上下方的所述横向注浆通道在柱状体的侧壁上的端口为直径方向的第一注浆出口和第二注浆出口，所述竖向注浆通道远离所述安装孔的一端为第三注浆出口。本发明能够在沉桩后通过第一、二、三注浆出口同时或者先通过第一注浆出口，再通过第二、三注浆出口注入到钢管桩的桩端周围土体内改善土体密度及结构强度，提高桩基的承载力。
