Supporting construction method based on prestressed pipe pile
The invention relates to the technical field of building construction, in particular to a supporting construction method based on prestressed pipe piles. The construction method comprises the steps that the distance between supporting points of the prestressed pipe pile during supporting is determined according to shearing force; supporting is conducted through a static pressure method, and static pressure construction is adjusted by analyzing shearing force changes in real time; whether the prestressed pipe pile is reinforced or not is determined according to the shear force change; the prestressed pipe piles are reinforced according to the construction displacement of the reinforced single prestressed pipe pile; distance measurement is conducted on the constructed prestressed pipe piles, the manufactured crown beam steel bars are placed, and a half-grid crown beam steel bar structure is formed; after the top beam steel bars are placed, the top beam steel bars and the prestressed pipe piles are integrally poured, the foundation supporting construction efficiency and adaptability to various geologies are improved, the influence on the environment is small, the bearing capacity is high, the stability is high, and the follow-up maintenance and reinforcement cost is lower.
本发明涉及建筑施工技术领域，尤其涉及一种基于预应力管桩的支护施工方法。该施工方法包括：根据剪力确定支护时预应力管桩支点间的间距；通过静压法进行支护，实时分析剪力变化调整静压施工；根据剪力变化确定是否对预应力管桩进行加固；根据加固后的单个预应力管桩的施工位移对预应力管桩进行补强；对施工完成的预应力管桩进行间距测量，安放制作的冠梁钢筋，形成半格网冠梁钢筋结构；冠梁钢筋安放后对冠梁钢筋和预应力管桩进行整体浇筑，提高了地基支护施工效率以及针对各种地质的适应性，对环境造成的影响较小，承载力强稳定性高，后续维修和加固的成本更低。
