Structural reinforced steel stand column pile
The invention relates to a structural reinforced steel column pile. The structural reinforced steel column pile comprises a concrete column pile and a steel lattice, the lower end of the steel lattice is inserted into the concrete column pile to form a steel lattice anchoring section, a drill hole is formed in the center of the concrete column pile and extends from a pile top of the concrete column pile to the inside of the concrete column pile, the depth of the drill hole is larger than that of the anchoring section of the steel lattice, a steel pipe is fixedly arranged in the drill hole, and the upper end of the steel pipe is flush with the upper end of the steel lattice. According to the structural reinforced steel column pile, the steel pipe for reinforcement is additionally arranged on the concrete stand column pile, so that the structural strength of an original steel stand column pile is improved, the optimized steel stand column pile is obtained, powerful support is provided for a trestle plate, a safe and reliable unearthed route is provided for a large-scale operation vehicle to transport soil of a deep foundation pit, and the requirement of a new unearthed mode on the bearing capacity of the trestle plate is met.
本发明涉及一种结构补强的钢立柱桩，包括混凝土立柱桩和钢格构，所述钢格构下端插入所述混凝土立柱桩中，形成钢格构锚固段，所述混凝土立柱桩的中心设有钻孔，所述钻孔从混凝土立柱桩的桩顶开始向桩内延伸，且该钻孔的深度大于所述钢格构锚固段的深度，所述钻孔内部固定设有钢管，所述钢管的上端部与所述钢格构的上端部平齐。本发明通过在混凝土立柱桩增设一根用于补强的钢管，提高了原有的钢立柱桩结构强度，获得优化后的钢立柱桩，为栈桥板提供强有力的支撑，为大型作业车运输深基坑的泥土提供安全可靠的出土路线，满足新出土方式对于栈桥板承载力的需求。
