Reinforced concrete precast pile construction method
The invention relates to the field of civil engineering, and particularly discloses a reinforced concrete precast pile construction method which comprises the following steps: a, leveling a site and positioning a power transmission device, b, constructing a uniform-section cement soil mixing pile, c, lifting a drill rod of a stirrer and stirring, d, constructing a variable-section mixing pile, and e, repeating the b, the c and the d to finish the construction of the variable-section mixing pile. F, sinking the reinforcement cage; g, pouring concrete; the expanded heads at the inner core pile end and the outer core pile end of the reinforced concrete precast pile act together, the pile end resistance is effectively improved, meanwhile, the radial reinforcement cage can enhance the mechanical property of the expanded heads and guarantee high strength, the expanded-base composite pile plays the advantages of the stiff composite pile and the expanded-base pile at the same time, the unit material strength utilization rate is increased, and the construction cost is reduced. The side friction resistance and the pile end resistance are exerted, the overall bearing capacity of a pile foundation is effectively improved, the construction cost is reduced, and meanwhile compared with a traditional wedge-shaped pile, the wedge-shaped composite pile on the upper section can increase the pile distance and reduce the construction cost.
本发明涉及土木工程领域，具体公开了一种钢筋混凝土预制桩施工方法，包括a、平整场地、动力传动装置定位：b、等截面水泥土搅拌桩施工：c、提升搅拌机钻杆、搅拌：d、变截面搅拌桩的施工：e、重复b、c、d完成变截面搅拌桩的施工；f、下沉钢筋笼；g、浇筑混凝土；本发明中钢筋混凝土预制桩内外芯桩端的扩大头共同作用，有效提高桩端阻力，同时放射状钢筋笼能够增强扩大头的力学性能并保证较高强，扩底复合桩同时发挥劲性复合桩和扩底桩的优点，提高单位材料强度利用率，侧摩阻力和桩端阻力的发挥，有效地提高桩基的整体承载力，降低工程造价，同时上段的楔形复合桩相比于传统楔形桩，能够提高桩间距，降低工程造价。
