Annular rib-shaped prestressed pipe pile combined type post-grouting device and construction method thereof
The invention relates to a ring-rib-shaped prestressed pipe pile combined type post-grouting device which comprises a ring-rib-shaped prestressed pipe pile body (1), a steel pile cap (2), a pile side closed type grouting device (3), a cast iron conical pile tip (4), a grouting outer pipe (5) and a grouting inner pipe (6). The pile side closed type grouting device (3) is provided with a hollow closed type grouting chamber (301) wrapped by a rubber capsule. The grouting outer pipe (5) is connected with a pile side transverse grouting pipe (501) through a spherical pressure cavity (502), and the side face of a permeable stone (504) wraps filling cotton to be embedded in an open type grout outlet (503). The mud jacking inner pipe (6) comprises a top pipe (601), a middle pipe (602) and a bottom pipe (603), and inflation air bags (605) are arranged on the upper portion and the lower portion of an inner pipe mud outlet (604) respectively. The method has the advantages that the grouting construction quality of the prestressed pipe pile is improved, the grouting area, the grouting pressure and the grouting amount are better controlled, and the bearing capacity of the prestressed pipe pile is improved.
本发明涉及一种环肋状预应力管桩组合式后压浆装置，包括环肋状预应力管桩桩身（1）、钢制桩帽（2）、桩侧闭式压浆装置（3）、铸铁质圆锥型桩尖（4）、压浆外管（5）和压浆内管（6），桩侧闭式压浆装置（3）设有橡胶胶囊包裹的中空闭式压浆室（301），压浆外管（5）通过球形压力腔（502）与桩侧横向压浆管（501）相连，透水石（504）侧面裹住填充棉嵌于开式出浆口（503）处；压浆内管（6）包括顶管（601）、中管（602）和底管（603），内管出浆口（604）的上下处分别设有充气膨胀气囊（605）。本发明的优点是提高预应力管桩压浆施工质量，更好地控制压浆区域、压浆压力及压浆量，提高预应力管桩承载能力。
