Pile end static pressure grouting pipe device of steel pipe pile and using method
The invention discloses a pile end static pressure grouting pipe device of a steel pipe pile and a using method. An adjustable core pipe grouting device is pressed into a required depth within a vertical projection range of a pipe wall of the steel pipe pile through static pressure; the adjustable core tube grouting device comprises a grouting floral tube core tube and a protective sleeve; a grouting opening is formed in the side wall of the grouting floral tube core tube, a conical guide head is arranged at the lower end of the grouting floral tube core tube, and the position connected with the conical guide head and the lower end of the protective sleeve are sealed; and a matched limiting structure is arranged between the upper end of the grouting floral tube core tube and the lower end of the protective sleeve, so that the protective sleeve is prevented from being separated from the upper end of the grouting floral tube core tube. When in use, the protective sleeve is pulled up, so that the core tube of the grouting floral tube is completely exposed, and grouting is carried out; and after grouting of the current depth is completed, the adjustable core pipe grouting device is pulled up again to the position above the grouting completion depth, and execution is repeated till all grouting is completed. The grouting pipe can be repeatedly used, and multiple times of grouting at any depth can be achieved.
本发明公开了钢管桩的桩端静压注浆管装置及使用方法，通过静压将活络芯管注浆装置压入钢管桩的管壁竖直方向投影范围内所需要的深度；活络芯管注浆装置包括注浆花管芯管和保护套管；注浆花管芯管的侧壁设有注浆口，下端设有锥形导向头，与锥形导向头连接的位置与保护套管的下端形成呈密封；注浆花管芯管的上端与保护套管的下端之间设有匹配的限位结构，防止保护套管从注浆花管芯管上端脱离。使用时，将保护套管拔起使注浆花管芯管完全露出并进行注浆；在完成当前深度注浆后，再次将活络芯管注浆装置拔起至完成注浆的深度的上方，并重复执行至完成所有注浆。本发明能够实现注浆管材的重复使用，实现任意深度的多次注浆。
