Method and equipment for reducing filling coefficient of cast-in-place pile in deep soft soil area
The invention relates to a method and equipment for reducing the filling coefficient of a cast-in-place pile in a deep soft soil area. The equipment comprises a pile hole located in a deep soft soil layer, and an annular hole is formed in the top of the pile hole; the reinforcement cage is positioned in the pile hole; the hook is positioned above the deep and thick soft soil layer; the water glass pouring assembly used for pouring water glass is located in the reinforcement cage and used for injecting the water glass when concrete grout is poured. The concrete pouring assembly is located in the reinforcement cage and used for pouring concrete grout into the pile hole; the protection assembly is located in the annular hole and used for preventing soil on the inner wall of the annular hole from collapsing and falling into the pile hole; the defects that in the prior art, the manufacturing process for wrapping a layer of iron sheet or an annular thermoplastic pipe on the periphery of a reinforcement cage is complex and high in cost, grout still continuously flows out of the pile bottom to the periphery of a hole, and exertion of side resistance of a soil layer around the pile is affected are overcome.
本发明涉及一种降低深厚软土地区中灌注桩充盈系数的方法及设备,包括位于深厚软土层内的桩孔,桩孔的顶部设有环形孔;位于桩孔内的钢筋笼;位于深厚软土层上方的挂钩;用于浇灌水玻璃的水玻璃浇灌组件位于钢筋笼内,用于在浇灌混凝土浆液时注入水玻璃;位于钢筋笼内的混凝土浇灌组件,用于向桩孔内浇灌混凝土浆液;位于环形孔内的防护组件,用于避免环形孔内壁的泥土塌方掉落至桩孔内;解决了现有技术中钢筋笼外围包裹一层铁皮或环状热塑管的制作工艺复杂且成本较高,浆液还是会从桩底不断流出至孔周,影响桩周土层侧阻力的发挥中的缺点。
