Precast pile for enhancing side friction resistance and construction method thereof
The invention discloses a precast pile for enhancing side friction resistance and a construction method thereof. The precast pile comprises a pile body, wherein an inner cavity is formed in the center of the pile body; an inclined channel is connected with the inner cavity and extends to the surface of the pile body; a cylindrical pile nail is arranged in the inclined channel; and a closed structure is arranged at the port of the inclined channel. The construction method comprises the following steps of: 1, sinking the pile; and 2, grouting and pressurizing. The precast pile has the advantage of easiness in construction; the influence of the inclined channel and the pile nail arranged in the pile body on the strength of the pile body is reduced to the greatest extent; the connection between the pile body and the surrounding soil is enhanced, the side friction resistance of the pile body is effectively enhanced, the bearing capacity is improved, and the required pile length is reduced, so that the precast pile has good economic benefits; and the angle of the inclined channel in the pile body and the grouting pressure can be adjusted according to the engineering requirements and different soil layer conditions, and the precast pile can be used for pressure-resistant piles and uplift piles and has high adaptability and flexibility.
本发明公开了一种增强侧摩阻力的预制桩及其施工方法，该预制桩包括桩体，在所述桩体的中心设有内腔，斜向通道与所述内腔相连并延伸至所述桩体的表面，所述斜向通道内设有柱形桩钉，所述斜向通道的端口处设有封闭结构。该施工方法包括步骤一、沉桩；步骤二、注浆加压。本发明具有易于施工的优势；最大程度减小在桩体内设置斜向通道及桩钉对桩体强度的影响；加强了桩体与周围土体的连接，有效增强桩体的侧摩阻力，提高承载能力，减少所需要的桩长，从而具有较好的经济效益；桩体内斜向通道的角度以及注浆压力的设计可以根据工程需求以及不同土层条件进行调整，既可用于抗压桩也可用于抗拔桩，具有较强的适应性、灵活性。
