Construction device and construction method for super-large-diameter cement soil tubular pile
The invention provides a super-large-diameter cement soil tubular pile construction device which comprises a tower, a lifting device is arranged on the tower and comprises a lifting rod and a clamping wheel for fixing the lifting rod, the bottom of the lifting rod is fixedly connected with a power head, the power head is connected with a power source, the lower portion of the power head is fixedly connected with a drilling barrel, and a plurality of stirring blades are arranged on the outer wall of the drilling barrel. A tubular pile cement paste conveying pipe and a bottom sealing cement paste conveying pipe in the vertical direction are arranged on the outer side and the inner side of the drilling barrel correspondingly, and the top of the tubular pile cement paste conveying pipe and the top of the bottom sealing cement paste conveying pipe are connected with two high-pressure slurry pumps through two-channel rotating joints correspondingly. A tubular pile nozzle and a bottom sealing nozzle are arranged at the lower ends of the tubular pile cement paste conveying pipe and the bottom sealing cement paste conveying pipe correspondingly, and drilling teeth are arranged at the bottom of the drilling barrel. The invention further provides a construction method of the super-large-diameter cement-soil tubular pile, high pressure and stirring are integrated, construction of the super-large-diameter tubular pile with the cement-soil tubular pile diameter being 1-2 m can be met, cement consumption is reduced, and construction efficiency is improved.
本发明提供了一种超大直径水泥土筒桩施工装置，包括塔架，塔架上设有提升装置，提升装置包括升降杆和固定升降杆的夹紧轮，升降杆的底部固定连接动力头，动力头与电源相连，动力头的下方固定连接钻筒，钻筒外壁设有若干搅拌叶片，钻筒外侧和内侧分别设有垂直方向的筒桩水泥浆输送管和封底水泥浆输送管，筒桩水泥浆输送管和封底水泥浆输送管的顶部通过双通道旋转接头分别与两台高压泥浆泵相连，筒桩水泥浆输送管和封底水泥浆输送管的下端分别设有筒桩喷嘴和封底喷嘴，钻筒的底部设有钻齿。本发明还提供一种超大直径水泥土筒桩施工方法，集高压和搅拌于一体，可以满足水泥土筒桩直径1~2m超大直径的筒桩的施工，降低水泥的消耗，提高施工效率。
