Pile side post-grouting cast-in-place pile structure
The invention relates to a pile side post-grouting cast-in-place pile structure which comprises annular grouting pipes, longitudinal slurry conveying pipes, longitudinal main reinforcements and spiral stirrups, a cast-in-place pile reinforcement cage is composed of the longitudinal main reinforcements and the spiral stirrups, the multiple longitudinal slurry conveying pipes are arranged in the cast-in-place pile reinforcement cage and used for replacing the longitudinal main reinforcements, the multiple annular grouting pipes are arranged, and the multiple annular grouting pipes are arranged in the cast-in-place pile reinforcement cage and used for replacing the longitudinal main reinforcements. The longitudinal slurry conveying pipe is used for replacing part of the spiral stirrups, the longitudinal slurry conveying pipe is communicated with the annular grouting pipe, grouting is carried out from bottom to top through a hole in the upper portion of the longitudinal slurry conveying pipe, and therefore annular grouting bodies are formed and distributed on the periphery of the cast-in-place pile body. The side friction resistance of the cast-in-place pile can be greatly improved, and meanwhile the cast-in-place pile has the beneficial effects of being safe, convenient and environmentally friendly.
本发明涉及一种桩侧后注浆灌注桩结构，包括环形注浆管、纵向输浆管、纵向主筋、螺旋箍筋，所述纵向主筋和螺旋箍筋组成灌注桩钢筋笼，所述灌注桩钢筋笼中设有多根纵向输浆管，用于替代纵向主筋，并设置多个环形注浆管，用于代替部分螺旋箍筋，所述纵向输浆管与环形注浆管相连通，通过纵向输浆管上部的孔洞自下往上进行压浆，从而形成环形注浆体分布于灌注桩桩体周边。本发明能极大提高灌注桩的侧摩阻力，同时具有安全性、便利性、绿色环保的特点。
