Bare rock riverbed high-strength hard rock guide hole steel sheet pile and construction method
The invention relates to a bare rock riverbed high-strength hard rock guide hole steel sheet pile and a construction method. The construction method comprises the construction steps of a steel sheet pile guiding and positioning pile sinking technology, a perpendicularity dynamic adjustment integral type guide frame technology, a rotary drilling guide hole concrete pouring anchoring technology, a steel waling reversed-sequence installation technology, a steel casing guide hole accurate positioning technology, a symmetrical annular high-pressure water jetting auxiliary pile sinking technology and a steel sheet pile cofferdam leakage efficient plugging technology. The invention belongs to the field of bridge engineering construction, not only can improve steel sheet pile positioning accuracy, pile sinking construction efficiency, steel sheet pile bottom anchoring stability, steel enclosing purlin installation accuracy, steel sheet pile cofferdam plugging effect and the like, but also improves construction quality and efficiency, greatly improves on-site hard rock layer steel sheet pile construction efficiency, saves manpower and cost, and reduces construction cost. And good technical and economic benefits can be obtained when the method is applied to practical engineering.
本发明涉及裸岩河床高强硬岩引孔钢板桩及施工方法，施工步骤包括：钢板桩导向定位沉桩技术、垂直度动态调整整体式导向架技术、旋挖钻引孔灌注混凝土锚固技术、钢围囹逆序安装技术、钢护筒引孔精确定位技术、对称环向高压射水辅助沉桩技术、钢板桩围堰渗漏高效封堵技术。本发明属于桥梁工程施工领域，不但可以提高钢板桩定位准确性和沉桩施工效率、钢板桩底部锚固稳定性、钢围檩安装精确性、钢板桩围堰封堵效果等，同时提高了施工质量和效率，大大提高现场硬岩层钢板桩施工效率，节省人力和成本，应用于实际工程中可取得较好的技术经济效益。
