Post-grouting construction method for pile bottom of cast-in-place pile
The invention relates to the field of building construction, in particular to a cast-in-place pile bottom post-grouting construction method which comprises the following steps: A, cast-in-place pile hole-forming construction; b, mounting a cast-in-place pile reinforcement cage and a grouting guide pipe; c, pouring concrete into the cast-in-place pile; d, splitting with clear water; and E, grouting. According to the post-grouting construction method for the pile bottom of the cast-in-place pile, before formal grouting construction is carried out, high-pressure clear water is injected into the grouting guide pipe, the high-pressure clear water is used for splitting the soil layer at the pile bottom of the cast-in-place pile, a pulse-shaped grouting channel is formed, and then concrete grout can be easily diffused to a set range along the formed grouting channel during grouting construction; and the forming quality of the vein-like network calculus body is ensured.
本发明涉及建筑施工领域，特别是涉及一种灌注桩桩底后注浆施工方法，包括下述步骤：A、灌注桩成孔施工；B、灌注桩钢筋笼安装及注浆导管安装；C、灌注桩混凝土浇筑；D、清水劈裂；E、注浆。本发明所述的一种灌注桩桩底后注浆施工方法，在正式进行注浆施工之前，往注浆导管注入高压清水，利用高压清水劈裂灌注桩桩底土层，形成脉状的注浆通道，进而在注浆施工时混凝土浆液沿成型的注浆通道能够容易的扩散至设定范围，确保了脉状网络结石体的成型质量。
