Bridge cast-in-place pile construction technology
The invention belongs to the field of bridge construction, and particularly discloses a bridge cast-in-place pile construction process which comprises the following specific steps: S1, preparing a precast pile; s2, preparation work; s3, drilling is conducted; s4, broaching is conducted; s5, hole cleaning; s6, precast pile installation; s7, pouring concrete; and S8, finishing the work. The bearing capacity of the cast-in-place pile is remarkably improved through the formed multiple bearing discs, the cast-in-place pile is suitable for various complex geological conditions, the construction efficiency is greatly improved by adopting the reinforced concrete precast pile, the overall quality strength of a pile body can be improved by matching the reinforced concrete precast pile with concrete to form the composite pile, and the construction cost is reduced. The problems of necking, segregation and even pile breakage of a pile body of the cast-in-place pile are effectively solved, the bottom concrete expansion head is formed after the concrete and the precast pile are solidified and connected to form the composite pile, the characteristic that the bearing capacity of a soil layer at the bottom of the pile is high is fully utilized, and the bearing capacity of the cast-in-place pile is greatly improved.
本发明属于桥梁施工领域，具体公开了一种桥梁灌注桩施工工艺，具体步骤如下：S1、预制桩制备；S2、准备工作；S3、钻孔；S4、扩孔；S5、清孔；S6、预制桩安装；S7、灌注混凝土；S8、结束工作；本发明通过形成的多个承力盘，显著提高灌注桩的承载力，并且适用于各种复杂地质条件，通过采用钢筋混凝土预制桩，大大提高施工效率，将钢筋混凝土预制桩与混凝土配合形成复合桩可以提高桩体的整体质量强度，有效解决灌注桩的桩身缩颈、离析，甚至断桩的问题，通过在混凝土与预制桩凝固连接形成复合桩后，形成底部混凝土扩大头，充分利用桩底土层承载力高的特点，大大提高灌注桩的承载力。
