Pile feeding construction method for tubular pile with closed pile core
The invention relates to the technical field of tubular piles, and discloses a pile core closed tubular pile conveying construction method, which comprises the following construction steps that (1) a tubular pile is constructed downwards in a soil layer, and a pile core is arranged in the tubular pile; the bottom of the tubular pile is embedded into a soil body, and the top of the tubular pile is exposed above the ground; (2) a pile plug device is embedded in the upper portion of the pile core, the pile plug device seals the pile core, and an interval section is arranged between the pile plug device and the top of the tubular pile; (3) a pile feeder is installed at the top of the pipe pile, the pile feeder drives the pipe pile downwards till the top of the pipe pile is embedded into a set position in the soil body, an empty pile section is formed above the pipe pile, and the empty pile section upwards penetrates to the ground; and (4) the pile feeder is dismantled, the empty pile section is filled with backfill soil, a backfill section is formed, and the backfill section abuts against the pile stopper from top to bottom. In this way, the pile core is sealed through the pile plug device, and the situation that after the pile feeder is detached, the pile core is filled with soil or cement paste, and consequently a reinforcement cage and core filling concrete cannot be constructed in the later period is avoided.
本发明涉及管桩的技术领域，公开了桩芯封闭的管桩送桩施工方法，包括以下施工步骤：1)、在土层中朝下施工管桩，管桩的内部具有桩芯；管桩的底部嵌入在土体中，管桩的顶部显露在地面的上方；2)、在桩芯的上部中嵌入桩塞器，桩塞器将桩芯封闭，桩塞器与管桩的顶部之间具有间隔段；3)、在管桩的顶部安装送桩器，送桩器将管桩朝下驱动，直至管桩的顶部嵌入在土体中的设定位置，管桩的上方形成有空桩段，空桩段朝上贯穿至地面；4)、拆除送桩器，利用回填土回填空桩段，形成回填段，回填段自上而下抵压在桩塞器上。这样，通过桩塞器将桩芯封闭，避免在送桩器拆出以后，桩芯被泥土或水泥浆填塞，导致后期钢筋笼及填芯混凝土无法施工。
