Construction method of concrete filled steel tube pile supporting structure
The invention relates to the field of foundation piles, in particular to a concrete filled steel tube pile supporting structure construction method which comprises the following steps: S1, construction preparation; s2, pile driving is conducted, specifically, a first pile is driven (or pressed) into the ground, and the first pile is pressed into the ground after the expanded head of the first pile faces downwards and the angle is adjusted through a pile pressing-in machine; s3, grouting is conducted, specifically, after construction of the first pile is completed, slurry is injected into a grouting hole of the first pile; s4, pressurization is conducted, specifically, after the grouting hole is filled with slurry, the upper end of the grouting hole of the first pile is blocked, continuous pressurization and grouting are conducted on the interior of the grouting hole, an expansion head is expanded through the slurry, and an inner cavity of a sealing plate is filled with the slurry; or a special rod piece is driven into or rotationally pressed into the expanding head to expand the expanding head, and the inner cavity of the sealing plate is filled with grouting. Slurry is injected into the grouting holes, the expanding head is expanded through the slurry or a special rod piece, the size of the lower end of the first pile is increased, the underground resistance of the first pile is increased, and then the overall bearing capacity is effectively improved.
本申请涉及一种钢管混凝土桩撑结构施工方法，涉及基础桩的领域，其包括以下步骤：S1，施工准备；S2，打桩，向地下打入(或压入)第一桩，通过压桩机将第一桩的扩大头朝下并调整好角度后压入地下；S3，灌浆，在第一桩施工完成后，向第一桩的注浆孔内注入浆料；S4，加压，在注浆孔内注满浆料后，对第一桩注浆孔的上端进行封堵，并向注浆孔内持续增压、注浆，通过浆料将扩大头撑开，使浆料注满封板内腔；或者采用专用杆件打入或旋转压入撑开扩大头，注浆填满封板内腔。本申请在注浆孔中注入浆料，通过浆料或者采用专用杆件撑开扩大头，使第一桩的下端体积增大，令第一桩在地下的阻力增大，进而有效提高整体的承载能力。
