Concrete pile construction method suitable for underground multi-layer karst cave structure
The invention discloses a concrete pile construction method suitable for an underground multi-layer karst cave structure, and relates to karst cave concrete pile application. Comprising the following steps that a pile pit penetrating through a karst cave is excavated, a hexagonal-prism-shaped reinforcement cage is manufactured, a traction supporting frame is manufactured at the bottom of the hexagonal-prism-shaped reinforcement cage, a concrete support is manufactured at the bottom of the hexagonal-prism-shaped reinforcement cage, hemispherical spring steel bars are manufactured, the hemispherical spring steel bars are welded to the hexagonal-prism-shaped reinforcement cage, and a reinforcement cage sleeve with a hemispherical sleeve is manufactured; the elastic reinforcement cage is wrapped with a reinforcement cage sleeve, the reinforcement cage sleeve is sleeved with an installation cylinder, the elastic reinforcement cage sleeved with the installation cylinder is put into the installation pit, the installation cylinder is taken down to enable the hemispherical spring to expand and be clamped in the karst cave, and concrete is poured into the elastic reinforcement cage and dried and solidified to be formed; according to the invention, the plurality of hemispherical reinforcing steel bar springs bulge out, and the hemispherical reinforcing steel bar springs with the hemispherical wrapping cloth block the karst cave part in the pile pit, so that the phenomena of slurry leakage, hole collapse, hole shrinkage, pile hole deflection and the like are avoided during concrete pouring.
一种适用于地下多层溶洞结构的混凝土桩施工方法，涉及一种溶洞混凝土桩应用，包括以下步骤：开挖穿越溶洞的桩坑、制作六棱柱形钢筋笼、在六棱柱形钢筋笼底部制作牵拉支撑架、在六棱柱形钢筋笼底部制作混凝土支座、制作半球形弹簧钢筋、在六棱柱形钢筋笼上焊接半球形弹簧钢筋、制作带有半球形套的钢筋笼套、用钢筋笼套包裹弹性钢筋笼、在钢筋笼套外部套接安装筒、将套接有安装筒的弹性钢筋笼投入装坑内、取下安装筒使半球形弹簧膨胀卡在溶洞处、在弹性钢筋笼内部灌注混凝土并干固成型；本发明利用多个半球形钢筋弹簧膨出，带有半球形包裹布的半球形钢筋弹簧堵住了桩坑内溶洞部位，灌注混凝土时避免了漏浆、塌孔、缩径、桩孔偏斜等现象的出现。
