Construction method of bridge drilling pile
The invention relates to a construction method of a bridge drilling pile. The method comprises the following steps that preparation is made for construction; measurement and paying-off are carried out, and a positioning rod is arranged in the center point of a pile position; a protective cylinder is embedded, and the bottom and periphery of the protective cylinder are filled with clay; slurry is prepared, wherein a slurry pond is manufactured for slurry preparation; drilling is performed; hole detection is carried out; hole cleaning is performed; a reinforcement cage is hoisted, wherein the reinforcement cage is hoisted immediately after hole cleaning; a guide pipe is hoisted, wherein the guide pipe is hoisted after the reinforcement cage is hoisted; concrete is poured; when the concrete is poured, the concrete has to be continuously poured, the pouring time cannot exceed the initial setting time of the first batch of concrete, and the guide pipe is slowly pulled up along with pouringof the concrete; a pile foundation is detected, wherein the integrity of the pile foundation is detected through instantaneous excitation time domain frequency domain analysis or ultrasonic detection.According to the construction method of the bridge drilling pile, the implementation level of the bridge drilling pile construction process can be effectively strengthened, the construction quality of the bridge drilling pile is effectively guaranteed, and the stability and safety of the bridge drilling pile are ensured.
本发明涉及桥梁钻孔桩的施工方法，包括以下步骤：施工准备；测量放线，在桩位的中心点打入定位杆；埋设护筒，护筒底部及周围夯填黏土；配置泥浆，制作泥浆池配置泥浆；钻孔；检孔；清孔；吊装钢筋笼，清孔结束后立即吊装钢筋笼；吊装导管，钢筋笼吊装完成后吊装导管；灌注混凝土，在灌注混凝土时，混凝土必须连续灌注，且灌注时间不能超出首批混凝土的初凝时间，导管随着混凝土的灌注缓慢拔起；桩基检测，对桩基的完整性采用瞬间激振时域频域分析法或超声波检测。本发明提供的桥梁钻孔桩的施工方法能切实加强桥梁钻孔桩施工工艺的实施水平，有效保证桥梁钻孔桩的施工质量，确保桥梁钻孔桩的稳定性和安全性。
